Description

  The present invention relates to a lamp installation method and a lamp installation structure, and in particular, includes a lower base and an upper base, for example, a lamp that forms a light emitting part such as a guide light for a runway on a road surface, and a roadbed part. The present invention relates to a lamp installation method and a lamp installation structure for embedding and installing in a pavement composed of a pavement.

  For example, on the runway of an airport, various aviation lights such as various guide lights, runway distance lights, runway center line lights, runway lights, approach angle indicator lights, installation zone lights, taxiway lights, taxiway center line lights, stop line lights, etc. A lamp used as a lamp is embedded in a pavement of a runway composed of a roadbed part and a pavement part, thereby forming a light emission part on the road surface, for example, various kinds for guiding an airplane at night It emits light (see, for example, Patent Document 1 and Patent Document 2). Such lamps need to be accurately mounted at a predetermined installation position so that the exact position of the taxiway can be clearly shown, for example, and support a heavy load from an airplane, for example, integrated with the roadbed and pavement. It is necessary to fix it as firmly as possible. In addition, the lamps are embedded and installed as foreign materials using metal materials and synthetic resin materials that are different from these asphalt materials in the upper layer roadbed by bituminous stabilization materials (asphalt stabilization materials) and pavements by asphalt mixtures. Therefore, in order to prevent a defective portion such as a crack from occurring in the pavement around the lamp, it is necessary to install it in the pavement in a state integrated with the surrounding pavement.

  For this reason, according to the conventional technology, as a method of installing the lamp, for example, “Aircraft Lighting / Electrical Equipment Common Specification, 1999” (1999) published by the Institute of Electrical Engineering, Japan In June, the standard specification is defined, and for example, the following method as shown in FIG. 7 is adopted.

  That is, for example, after constructing an upper layer roadbed with a bituminous stabilization material (asphalt stabilization material) above the lower layer roadbed with cement stabilization material (lower layer roadbeds (1), (2)), the lower base of the lamp Measure the installation position and conduit pipe position, remove the upper base roadbed of the lower base installation position by removing the core by circular boring, and cut the upper pipe base of the conduit pipe position with a concrete cutter and remove it. Thus, a pipe laying groove having a rectangular cross section is formed. After that, it is supported by the lower roadbed at the installation position of the cored lamp, and the lower base is installed to determine the installation, and the conduit is installed along the piping installation groove. And while filling resin around the installed lower base, the pipe laying groove is backfilled with goose asphalt, and the upper roadbed removed by performing core removal or cutting is restored.

In addition, the base layer of the pavement (base layers (1), (2)) is constructed using the aggregated asphalt concrete, covering the lower base of the installed lamp, above the restored upper layer roadbed. The surface layer is constructed using dense grained asphalt concrete. After construction of the pavement part, the pavement part directly above the lower base is cored by, for example, circular boring to form a lamp installation hole, and the upper base of the lamp is installed in this lamp installation hole. The lamp unit is embedded and fixed to the pavement by being joined and integrated with the base and filling the gap between the lamp installation hole and the lamp unit with resin. Finally, wiring is performed inside the conduit, and a lamp as a light emitting part is attached to the lower base of the lamp to complete the construction for installing the lamp.

  However, in the above conventional lamp installation method, after constructing the upper layer roadbed with asphalt stabilizing treatment material, the installation position of the lamp is cored by circular boring and the upper layer roadbed is removed, or the conduit pipe position is changed. Cutting with a concrete cutter, removing the upper layer base of the cut part and forming a pipe laying groove with a rectangular cross-section of considerable size is required, and the lower base of the lamp and the conduit are After installation, it requires work to restore the removed upper roadbed, so it is a time-consuming work, especially when many lamps are installed on the runway in a large area. And the construction cost will increase.

  Therefore, as an alternative to such a conventional lamp installation method, it is possible to establish an installation method that is excellent in workability and that can obtain the same positional accuracy and fixed state as the conventional lamp installation method. It was desired. In particular, in the conventional lamp installation method, after the upper layer roadbed is constructed, core removal and cutting are performed to remove the predetermined part of the upper layer roadbed, the lower base and the conduit are installed, and then the upper layer roadbed is restored again. The pavement will be constructed after waiting for it. For this reason, it is necessary to stop the construction for a long time until the upper roadbed is restored, and the construction from the upper roadbed using Alphalt material to the construction of the pavement is followed as a series of civil engineering work. Therefore, it was difficult to carry out continuously, so efficient construction was not performed.

  The present invention has been made by paying attention to such a conventional problem, and while accurately shortening the construction period and reducing the construction cost, the lamp and the conduit connected to the lamp are accurately fixed inside the pavement. A lamp installation method that can be installed in an installed state and can be installed efficiently while performing the construction of upper roadbed and pavement using alfalto material continuously as a series of civil engineering works in a chasing manner And it aims at providing a lighting installation structure.

  The present invention consists of a lower base and an upper base, embedded in a pavement comprising a roadbed part including a lower roadbed by a cement-stabilized material and an upper layer roadbed by an asphalt-stabilized material, and a pavement part by an asphalt mixture. In the lamp installation method for installing a lamp forming a light emitting part on a road surface on the pavement, the lower part is formed via a base plate integrally joined to a bottom part of the lower base after the formation of the lower layer roadbed. A base is installed on the upper surface of the lower roadbed, and the lower base is fixed to the lower roadbed by inserting and anchoring the anchor member into the lower roadbed via the anchor hole provided in the protruding portion of the base plate. Connecting to the lower base and piping a conduit to the upper surface of the lower roadbed, and placing a predetermined interval in the piping direction on both sides of the conduit. The anchor member is inserted into the lower roadbed to solidify, the step of positioning the conduit, the step of constructing the upper roadbed above the lower roadbed, the upper baseboard covering the lower base A step of constructing the pavement portion above, a core installation of the pavement portion directly above the lower base to form a lamp installation hole, and an arrangement of the upper base in the lamp installation hole And achieving the above object by providing a lamp installation method comprising the step of joining and integrating with the lower base, and then filling the gap between the lamp installation hole and the lamp. It is.

  And according to the lamp installation method of the present invention, when piping the conduit, a piping groove is formed on the upper surface of the lower roadbed along the piping position, and the substantially lower half of the conduit having a circular cross section is provided. It is preferable to pipe the conduit so that the portion is embedded in the pipe groove.

  Further, according to the lamp installation method of the present invention, in the step of fixing the lower base to the lower layer roadbed and the step of positioning the conduit, the insertion hole is formed in advance at the insertion position of the anchor member of the lower layer roadbed. It is preferable that the anchor member is inserted into the lower layer roadbed through the insertion hole.

  Furthermore, according to the lamp installation method of the present invention, it is preferable to inject a filling and solidifying material into the insertion hole before inserting the anchor member toward the insertion hole.

  Further, the present invention is a lamp installation structure in which a lamp composed of a lower base and an upper base is embedded in a pavement by the lamp installation method, and is integrally joined to the bottom of the lower base. The lower base is installed on the upper surface of the lower layer roadbed by the cement stabilizing treatment material through the base plate, and the anchor member is inserted into the lower layer roadbed through the anchor hole provided in the overhanging portion of the base plate and solidified. Thus, the lower base is fixed to the lower base, and the conduit is connected to the lower base and is piped on the upper surface of the lower base, and on both sides of the conduit, the piping direction The anchor pipe is inserted into the lower layer roadbed and fixed at a predetermined interval, so that the conduit is positioned on the upper surface of the lower layer roadbed. An upper layer roadbed made of a bottom stabilization material is laid above the lower layer roadbed, a pavement is formed above the upper layer roadbed and the lower base, and the pavement in the portion directly above the lower base is cored. A lamp constructed by installing the upper base in a hole installation hole in which an opening is formed and joining and integrating with the lower base, and filling a gap between the lamp and the pavement. By providing an installation structure, the above object is achieved.

  According to the lamp installation method or lamp installation structure of the present invention, the lamp and the conduit connected to the lamp are embedded in the pavement with high accuracy while shortening the construction period and reducing the construction cost. In addition to being able to be installed, it is possible to efficiently construct the upper layer roadbed and pavement using alfalto material while continuously performing the chasing method as a series of civil engineering work.

  The lamp installation method and the lamp installation structure according to a preferred embodiment of the present invention shown in FIGS. 1 and 2 are, for example, a large number of lamps 10 used as guide lights on a pavement 11 constituting a runway of an airfield. In order to maintain the desired position accuracy and stable fixed state, it is possible to embed and install efficiently while shortening the construction period and reducing the construction cost compared with the installation method defined in the conventional standard specifications. It was developed as a method and structure.

  That is, the lamp installation method of the present embodiment includes the lower base 12 and the upper base 13, and the lower roadbeds 14a and 14b made of cement-stabilized material and the upper roadbed 15 made of asphalt-stabilized material (bitumen stable treated material). As a method for installing on the pavement 11 a lamp 10 that is embedded in a pavement 11 composed of a roadbed part 16 including a pavement part 19 made of an asphalt mixture and forms a light emitting part by a lamp 21 on a road surface 20. It has been adopted.

And the lamp installation method of this embodiment includes the following processes [a]-[e].
[A] After the formation of the lower roadbeds 14a and 14b, the lower base 12 is installed on the upper surface of the lower roadbed 14b via the base plate 22 integrally joined to the bottom of the lower base 12 and provided on the protruding portion of the base plate 22 A step of fixing the lower base 12 to the lower roadbed 14b by inserting the first anchor member 24 into the lower roadbed 14b through the anchor hole 23 and solidifying it,
[B] The lower pipe 12 is connected to the lower base 12 to pipe the conduit 25 on the upper surface of the lower layer roadbed 14b, and the second anchor member 26 is placed on both sides of the conduit 25 at a predetermined interval in the pipe direction. The step of positioning the conduit 25 by inserting into 14b and solidifying,
[C] The process of constructing the upper layer roadbed 15 above the lower layer roadbed 14b,
[D] a process of covering the lower base 12 and constructing the pavement 19 above the upper roadbed 15;
[E] The pavement 19 in the portion directly above the lower base 12 is cored to form a lamp installation hole 27, and the upper base 13 is disposed in the lamp installation hole 27 and joined to the lower base 12. The step of integrating and then filling the gap 28 between the lamp installation hole 27 and the lamp 10.

  According to the installation method of the present embodiment, prior to the step of fixing the lower base 12 of the lamp 10 of [a] to the lower roadbed 14b, as shown in FIG. By the same construction method, the road bed leveling work, the lower roadbed work of the lower layer 14a, and the lower roadbed work of the upper layer 14b are constructed. That is, in the roadbed leveling work, for example, by rolling and rolling sandy soil with a predetermined thickness in a plurality of layers, the roadbed is formed by sufficiently compacting so as to obtain a desired support strength. .

  In addition, the lower layer subbase 14a is composed of a granular subbase or a cement-stabilized subbase, and, for example, performs leveling with a motor grader and performs compaction rolling with a load roller as in the conventional method. And a predetermined thickness designed in advance is formed. Further, the upper lower layer roadbed 14b is composed of a crushed stone stable treatment roadbed, and, similarly to the lower layer lower roadbed 14a, for example, leveling with a motor grader and compaction rolling with a load roller are performed in advance. The predetermined thickness is formed. Note that the upper lower layer roadbed 14b becomes a base layer of the lower base 12 of the lamp 10, and the lower base 12 and the conduit 25 are directly placed on the completed road surface of the lower layer base 14b. It is extremely important to ensure the flatness. Therefore, it is desirable to perform the leveling work of the upper lower layer roadbed 14b using an asphalt finisher, a spreader, or the like.

  According to the present embodiment, in the step of fixing the lower base 12 of the lamp 10 of [a] to the lower layer roadbed 14b, first, the lower base 12 is installed on the completed road surface of the lower layer roadbed 14b by, for example, coordinate surveying. Specify location. Next, for example, the base plate 22 has a shape that coincides with a rectangular base plate 22 having a size of about 200 to 300 mm, for example, which is integrally joined to a cylindrical lower base 12 having an outer diameter of about 200 to 300 mm. As a ruler member for forming the insertion hole 29 in advance, for example, a plastic temporary placement plate (not shown) having an anchor hole matching the anchor hole 23 formed at the four corners and having a thickness of about 10 mm is used. Temporarily placed at the installation position of the lower base 12 measured on the lower layer roadbed 14b. Then, the insertion hole 29 is previously formed at the insertion position of the first anchor member 24 into the lower layer roadbed 14b by drilling, for example, using a φ22 mm hammer drill from the anchor hole of the temporary placing plate toward the lower layer roadbed 14b. A perforation is formed (see FIG. 3).

  When the insertion hole 29 is formed in the lower layer roadbed 14b, the temporary placing plate is removed, and as shown in FIG. 3, the base plate 22 is attached to the anchor base hole at the installation position of the lower base 12 measured on the completed road surface of the lower layer roadbed 14b. 23 is accurately positioned and installed in a state of being aligned with the insertion hole 29. Further, for example, the first anchor member 24 made of a dog nail having a diameter of about 13 to 16 mm and a length of about 250 to 350 mm is inserted into the insertion hole 29 through the anchor hole 23 until the head portion 24a is in close contact with the base plate 22, and is solidified. As a result, the lower base 12 is fixed to the lower layer roadbed 14b.

  Here, prior to inserting the first anchor member 24 into the lower layer roadbed 14b, an insertion hole 29 is formed in advance, so that the first anchor member 24 is attached to the tip of the breaker, for example, and driven into the lower layer roadbed 14b. Compared to the case, the first anchor member 24 can be inserted into the lower roadbed 14b with high accuracy while effectively avoiding the displacement of the base plate 22 from the installation position due to vibration of the breaker or the like. Prior to inserting the first anchor member 24, for example, a cement paste mainly composed of special cement is poured into the insertion hole 29 as a filling solidifying material 30 for rooting up to, for example, about 50% of the hole depth. It is preferable. As a result, when the first anchor member 24 is inserted into the insertion hole 29, the filling solidified material 30 is solidified in a state where the gap between them is filled, thereby firmly solidifying the first anchor member 24. Thus, it is possible to more effectively avoid the displacement of the lower base 12 when the upper roadbed 15 and the pavement 19 described later are constructed.

  As the filling and solidifying material 30 for solidifying the first anchor member 24, for example, a non-shrink mortar, an acrylic resin mortar, a non-shrink grout material, and an epoxy resin are used in addition to the cement paste mainly composed of the above-mentioned special cement. Various known filling and solidifying materials for fixing bolts such as a two-component grout material as a main component can be used. Further, when the lower base 12 is fixed to the lower layer roadbed 14b, the base plate 22 is set on the completed road surface while the anchor hole 23 is aligned with the insertion hole 29, and the first anchor member 24 is floated once. After the insertion into the insertion hole 29, it is preferable to confirm the positions of the lower base 12 and the base plate 22 again, and then insert the first anchor member 24 into the filling solidified material 30 and fix it. Further, when unevenness remains on the completed road surface of the lower layer roadbed 14b on which the base plate 22 is installed, the lower layer roadbed is formed so as to have a flat surface using dry sand or the like so as not to generate a gap therebetween. The height of the upper surface of 14b is adjusted suitably.

  In the step of connecting the lower pipe 12 to the lower base 12 and positioning the electric pipe 25 on the upper surface of the lower layer roadbed 14b, the piping of the electric pipe 25 is first performed on the completed road surface of the lower layer roadbed 14b by, for example, coordinate surveying. Specify location. Next, as shown in FIG. 1, a conduit 25 having an inner diameter of, for example, about 25 to 50 mm is piped on the upper surface of the lower layer roadbed 14b along the measured piping position, and as shown in FIG. The conduit 25 is positioned by inserting the second anchor member 26 into the lower roadbed 14b and solidifying it on both sides of the conduit 25 using the band-type fixing bracket 31. The conduit 25 is joined to the lower base 12 via a known flexible joint, a Victorian joint, or the like.

  Here, in this embodiment, when piping the conduit 25, the piping groove 32 is formed on the upper surface of the lower layer roadbed 14b along the piping position, and the substantially lower half portion of the conduit 25 having a circular cross section is formed in the piping groove. It is preferable to pipe the conduit 25 so as to be embedded in 32. As a result, when the upper roadbed 15 and the pavement 19 described later are constructed, even if a construction vehicle such as a work vehicle or asphalt finisher passes over the conduit 25, the displacement from the piping position is more effective. It is possible to prevent the occurrence of cracks in the upper roadbed 15 and the pavement 19 more effectively.

  In order to perform piping so that the substantially lower half of the conduit 25 is embedded in the piping groove 32, for example, immediately after finishing construction of the lower roadbed 14b which is a cement stabilization layer, the piping position is measured and marked on the completed road surface. At the same time, the cement-stabilized material at the marking position is gently scraped with a small back fore with a rigid claw attached to the tip of the bucket. After that, a groove forming machine capable of forming a groove having a semicircular cross-sectional shape is formed, or a dummy tube corresponding to the tube diameter of the conduit 25 is laid along the piping position, and a dummy is formed. By rolling the tube from above and removing the dummy tube, the pipe groove 32 having a semicircular cross section is formed in a concave shape. Then, the conduit 25 is laid in the formed piping groove 32, and the upper portion and the periphery thereof are tightened to remove the irregularities around the tube and the bottom surface, and stabilize the lower roadbed 14b in the portion where the conduit 25 is laid. When these operations are completed, a bitumen emulsion (asphalt emulsion) is applied in an amount of 0.8 to 1.0 L / m @ 2 for the purpose of drying the lower roadbed 14b, which is a cement-stabilized layer, and preventing inundation of rainwater. Disperse with.

  When the conduit 25 is piped on the upper surface of the lower layer roadbed 14b, the second anchor member 26 and the band-type fixing bracket 31 are used, for example, on both sides of the conduit 25 with a pitch in the piping direction of about 2 to 4 m. The conduit 25 is positioned and fixed by inserting the second anchor member 26 into the lower roadbed 14b. Also in the positioning operation of the conduit 25, the insertion hole 33 is formed in advance at the insertion position of the second anchor member 26 by drilling with a hammer drill of φ22 mm, for example, toward the lower roadbed 14b. Then, similarly to the case of the first anchor member 24, for example, cement paste mainly composed of special cement is poured into the formed insertion hole 33 as a filling solidified material 34 to about 50% of the hole depth. Thereafter, the anchor hole 35 of the band-type fixing bracket 31 is aligned with the insertion hole 33, and the anchor hole 35 is moved until the head 26a is in close contact with the base portion 31a of the band-type fixing bracket 31. Then, the electric pipe 25 is positioned and fixed at the piping position of the lower layer roadbed 14b by being inserted into the insertion hole 33 and solidified.

  In addition, as a method of positioning the conduit 25 by the second anchor member 26, a method of pressing and fixing the conduit 25 by the second anchor member 26 inserted into the lower layer roadbed 14b via the band-type fixing bracket 31 is used. In addition, the second anchor member 26 is processed into a shape including a portion for pressing the conduit 25 such as a U-shape or a G-shape, and the conduit 25 is directly pressed from above by the second anchor member 26. Thus, a fixing method or the like can be employed.

  In the above-mentioned step [c] of constructing the upper layer roadbed 15 above the lower layer roadbed 14b, the asphalt stabilization treatment material is leveled by, for example, a motor grader and tightened by a load roller by the same method as conventional asphalt pavement. The upper layer roadbed 15 is formed with a predetermined thickness while preliminarily rolling and compacting so as to embed the lower base 12 and the electric conduit 25 installed on the upper surface of the lower layer roadbed 14b.

  The upper roadbed 15 around the lower base 12 needs to be compacted more carefully and carefully. For example, it is sufficiently compacted using a Vibro plate of about 100 to 150 kg. Further, in the connection portion between the lower base 12 and the conduit 25, a gap is easily formed between the lower base 14b below the conduit 25 (see FIG. 1), causing cracks, and paving. 11 is affected, so that the gap portion is preferably filled with a heated asphalt mixture and sufficiently compacted. Furthermore, in the present embodiment, the conduit 25 embedded in the upper layer roadbed 15 has a substantially lower half portion embedded in the piping groove 32, and only a substantially upper half portion is formed without generating a gap below both sides of the circular cross section. Projecting above the lower roadbed 14b (see FIG. 4), the upper layer roadbed 15 around the conduit 25 is sufficiently compacted to effectively avoid the occurrence of cracks and a decrease in durability. It becomes possible to do.

  In the step of covering the lower base 12 of the above [d] and constructing the pavement 19 above the upper roadbed 15, the asphalt mixture sufficiently heated and mixed immediately before pavement, for example, by the same method as conventional asphalt pavement, By spreading with an asphalt finisher and compacting with high compaction energy using a tire roller or a tamper, two upper and lower base layers 17a, 17b made of a grain-graded asphalt concrete and a surface layer 18 made of a dense-graded asphalt concrete Is formed to cover the upper portion of the lower base 12 with a predetermined thickness designed in advance.

  Here, when the pavement 19 is formed, a wooden board is preferably attached to the upper surface of the lower base 12 as the base protection plate 36 (see FIG. 5). The base protection plate 36 can effectively prevent the lower base 12 from being damaged during the construction of the pavement 19. Moreover, when the base protection plate 36 is made of a wooden plate, the cutting edge of the boring cutter is lowered to the lower base 12 when the preceding boring 37 or the circular boring 38 for forming the lamp installation hole 27 is performed as described later. It is possible to easily detect that the upper end portion of the drill has been reached without damaging the cutting edge, and when the boring by the boring cutter is performed with a position offset from directly above the lower base 12, It is possible to easily detect a misalignment.

  In the step [e], a lamp installation hole 27 is formed in the pavement 19 and the upper base 13 is disposed, and in the process of joining and integrating with the lower base 12, it is the same as the method according to the conventional standard specification. By this method, the upper base 13 of the lamp 10 is integrated with the lower base 12 and is fixedly installed in the lamp setting hole 27. That is, at the stage where the upper layer roadbed 15 and the base layers 17a and 17b and the surface layer 18 of the pavement 11 are completed, the lower base 12 is located (the center point of the lower base 12) and surveyed. As shown in FIG. 1, pilot boring is performed by, for example, preceding boring 37 using a core boring machine having a bore diameter of 10 cm. Since the boring operation by the preceding boring 37 is intended to perform the circular boring 38 correctly, there is no deviation between the center point of the lower base 12 and the cutting edge center point of the preceding boring 37 obtained by surveying. Do carefully. Then, when the preceding boring 37 is completed, for example, the main boring with the circular boring 38 is performed using a cutting edge having a shape matching the lower base 12, and the lamp installation hole 27 is formed to a depth reaching the lower base 12. .

  When the lamp installation hole 27 is formed by the circular boring 38, the height from the base protection plate 36 installed on the upper surface of the lower base 12 to the road surface 20 is accurately measured, and the center point of the lower base 12 is measured. Is accurately measured, and the gradient of the upper surface of the lower base 12 is accurately measured. Moreover, as shown in FIG. 1, the taper gym 39 manufactured according to the measurement result is suitably attached to the upper surface of the lower base 12 from which the base protection plate 36 is removed. After that, for example, oil stains and the like adhering to the upper surface of the taper gym 39 and the lower surface of the upper base 13 are carefully wiped with a waste cloth and the like, and a primer is applied. A sealing material is applied to the adhesive surface with the adhesive 13. Then, the lower base 12 and the upper base 13 are integrally fixed by firmly tightening the connection bolt with a predetermined torque.

  When the upper base 13 is joined and integrated with the lower base 12, a primer is applied to the outer peripheral surfaces of the upper base 13 and the taper gym 39 installed in the lamp installation hole 27, and these outer peripheral surfaces and the lamp are installed. For example, an epoxy resin is filled and solidified in the gap 28 between the inner periphery of the hole 27 and the gap 28 is filled. In addition, when filling the epoxy resin, in order to prevent the road surface 20 from being soiled or to prevent the resin from entering the upper base 13, a masking tape is attached around the filling portion for protection.

  Further, for example, after the gap 28 around the lamp 10 is stuffed, the conduit 25 is cleaned in the tube and the cable is wired inside the conduit 25. Here, in-pipe cleaning, for example, as shown in FIG. 6, a cleaning body 40 having a size equivalent to a plug / reset inserted into the conduit 25 and protected by a waste cloth is attached to a pilot cable 41, This is performed by operating the cable 41 to reciprocate the cleaning body 40 in the pipe. The pilot cable 41 for cleaning is inserted from the lower base 12 side. In addition, the work of wiring the cable inside the conduit 25 is performed by inserting the cable from the lower base 12 side, so that the plug and the receptacle will not come off even if tension is applied to the wired cable due to some influence. As described above, an extra length (clearance) is provided in the vicinity of the lower base 12 and the connection portion.

  After wiring the cable to the conduit 25, finally, a lamp 21 as a light emitting unit is installed at the upper end of the upper base 13. When installing the lamp 21, check that the gasket on the lamp 21 side is attached, and connect the P3-A plug to the P3-C receptacle in the upper base 13, for example, and connect the connection bolt with the specified torque. Tighten and fix.

  And according to this embodiment, as shown in FIG. 1, the lower base 12 is attached to the bottom of the lower base 12 via the base plate 22 integrally joined by the lamp installation method including the steps as described above. By installing the first anchor member 24 on the lower roadbed 14b through the anchor hole 23 provided in the overhanging portion of the base plate 22 and solidifying the lower baseboard 14b with the cement stabilizing treatment material, The platform 12 is fixed to the lower roadbed 14b, connected to the lower base 12 and the conduit 25 is piped on the upper surface of the lower roadbed 14b, and at a predetermined interval in the piping direction on both sides of the conduit 25. In this case, the second anchor member 26 is inserted into the lower roadbed 14b and solidified, whereby the conduit 25 is positioned on the upper surface of the lower roadbed 14b. An upper layer roadbed 15 made of asphalt stabilizing material is laid and laid above the lower layer roadbed 14b, and a pavement 19 is formed above the upper layer roadbed 15 and the lower base 12, and the pavement 19 directly above the lower base 12 is formed. The upper base 13 is installed in the lamp installation hole 27 formed by opening the core and joined to the lower base 12, and the gap 18 between the lamp 10 and the pavement 11 is filled. The lamp installation structure comprised by this will be provided.

  Moreover, according to the lamp installation method and lamp installation structure of the present embodiment, the lamp 10 and the conduit 25 connected to the lamp 10 are accurately placed inside the pavement 11 while shortening the construction period and reducing the construction cost. It is possible to embed and install in a well-fixed state, and to efficiently construct the upper roadbed 15 and the pavement 19 using the alfalt material as a series of civil engineering work in a continuous manner. .

  That is, according to the present embodiment, the lower base 12 is fixed to the upper surface of the lower roadbed 14b via the base plate 22 by inserting and solidifying the first anchor member 24 into the lower roadbed 12b made of a cement stabilizing treatment material. At the same time, the second anchor member 24 is inserted on both sides of the electric pipe 25 so that the electric pipe 25 is positioned, so that the installation position and the piping position are firmly held, and the upper roadbed 15 It is possible to embed and install the lower base 12 and the electric conduit 25 in the state of being accurately fixed inside the pavement 11 without causing a large positional shift during construction of the pavement 19.

  In addition, since the lower base 12 and the conduit 25 can be installed prior to the construction of the upper layer roadbed 15 after the formation of the lower layer roadbed 12b, the upper layer roadbed 15 formed of the asphalt stabilizing material is formed. Therefore, there is no need to perform operations such as core removal or cutting of the upper layer roadbed 15 or restoration of the upper layer roadbed from which the upper layer roadbed 15 has been removed, which makes it possible to simplify the construction and significantly reduce the construction period and construction cost.

  Furthermore, since the pavement portions 17a, 17b, and 18 can be subsequently constructed after the upper layer roadbed 15 is constructed, a series of works from the construction of the upper layer roadbed 15 using the alfalt material to the construction of the pavement portion 19 are performed. As a civil engineering work, the chasing method can be continuously performed, and the lamp 10 can be embedded and installed in the pavement 11 more efficiently.

  In addition, as a result of performing various test constructions, the inventor can easily obtain the installation accuracy equivalent to the lamp installation method defined in the conventional standard specification according to the lamp installation method of the present invention, It was confirmed that it was possible to obtain a stable burial installation state, and that the construction yield and construction cost could be effectively reduced by greatly reducing the construction yield.

  The present invention is not limited to the above embodiment, and various modifications can be made. For example, when piping a conduit tube, a conduit groove is formed on the upper surface of the lower layer roadbed along the piping position, and the conduit tube is piped so that a substantially lower half portion of the conduit tube having a circular cross section is embedded in the conduit groove. There is no necessity. Further, in the step of fixing the lower base to the lower layer roadbed or the step of positioning the conduit, it is not always necessary to form the insertion hole in advance in the insertion position of the anchor member of the lower layer roadbed.
