[Technical background of the invention and its problems]

Beacon lights are buried in airport runways, taxiways, etc. with their floodlight windows exposed above the road surface, and the electric wires that illuminate these beacon lights are buried underground.

However, over the years, it has become necessary to raise these road surfaces for reinforcement, etc., but conventional construction methods involve burying the old marker lights and burying new marker lights on the raised road surface. Ta. However, this method not only required the procurement of new marker lights, but also required the installation of new electric wires near the new marker lights, which required a large amount of expense.

[Purpose of the invention]

An object of the present invention is to provide a construction method for reusing embedded marker lights during road surface raising work.

[Summary of the invention]

A protective device having a mounting part located on the top surface corresponding to the center of the base is attached to the base of a marker light buried in the road surface to close the opening, and then the road surface is raised. Then, a pilot hole is dug in the raised road surface and the mounting part of the protective equipment is exposed in this hole.
Next, attach the pilot shaft to the mounting part, mark the position of the embedded hole corresponding to the base on the road surface using this axis as a reference, then dig the embedded hole according to the marking, and remove the exposed base. This is a construction method that reuses the old base and electric wires by removing the protective equipment from the lamp and attaching the light body.

[Embodiments of the invention]

The details of the present invention will be explained with reference to the drawings. First, the condition of the road surface will be outlined using FIG. 1 is a road surface such as a runway or a taxiway, 2 is a marker light buried in the road surface 1, and 3, 3 is an electric wire buried in the road surface 1 and connected to the marker light 2.

Note that 49 is an O-ring provided on the main body 41.

Then, as shown in FIG. 6, a new road surface 51 is formed by raising the surface of the road surface 1 using a paving material 5, such as asphalt, and the base body 21 with the protective equipment 4 attached thereto, along with the electric wires 3, It is buried under the road surface 51 after being raised.

Next, as shown in FIGS. 7 and 8, a pilot hole 6 is dug in the raised road surface 51, and when a part of the protective cover 47 of the protective equipment 4 is exposed, it is crushed and the pilot plate 46 is removed. expose. Then, when two or three signs 45, 45 are visible, dig in the direction in which they converge to expose the fixture 48.

Therefore, as shown in Figures 9 and 10,
The mounting tool 48 is removed, and the pilot shaft 7 is screwed into the mounting portion 44 and fixed instead. This pilot shaft 7 is a round bar long enough to reach the surface of the road surface 51 after being raised, and has a screw carved into its tip.
When attached, it stands up almost vertically from the protector 4. Therefore, a template 8 is attached to this pilot shaft 7. As shown in the figure, this template 8 has a mounting hole 81 in the center of the metal disc through which the pilot shaft 7 is closely inserted. Same diameter as insertion hole 11)
A plurality of arcuate slits 82, 82...
The edges of this slit 82 form a painted line 83. The template 8 is then placed on the road surface 51 with the pilot shaft 7 as the center as shown in the figure. So, for example, Lutzker spray can 84
When a lacquer is applied to the slits 82, 82, .

Therefore, as shown in FIG. 12, the pilot shaft 7 is removed and the embedded hole 9 is dug along the mark 85 to expose the protector 4 and the base 21. At this time, if the mounting portion 44 is a threaded hole, a bolt may be attached to prevent the asphalt piece from entering the hole.

Therefore, as shown in FIG. 13, the protector 4 is removed, and the adjustment ring 22 and lamp body 24 are attached to the base 21 with the fixing tool 23 via the spacer 25. In this case, the adjustment ring 22 and the lamp body 24 may be old ones that can be reused as they are, or only new ones can be used.

As described above, in the method of this embodiment, the road surface 1 is raised after the protective equipment 4 is attached to the existing light body 21 and the opening is closed, so that the paving material 5 does not enter into the light body 21. There is no risk of damage, even if it is pressed by rollers during construction, and there is no problem in reusing it. Further, since the base 21 may be embedded, the raising work is easy and the finish is good. Furthermore, when excavating after the raising work, the direction in which the fixture 48 is located can be easily determined by simply digging a small pilot hole 6, so the fixture 48 can be easily excavated by simply digging a little further. Furthermore, the mounting part 4
A pilot shaft 7 is attached to 4, and the range of the embedded hole 9 to be dug is indicated using this shaft 7 as a reference.
The position and size of the embedding hole 9 can be specified accurately, construction work can be carried out without waste, and the finish can be accurate and neat. In this construction, at least the base 21 and the electric wires 3, 3 can be used as they are, so the cost and construction schedule can be significantly reduced, and the finished product is good. Then, by this method, the diameter of the new embedding hole 9 is set to the diameter of the base + 20 mm.
Can be opened concentrically within

Next, another example of the main body 41 of the protective equipment 4 is shown in the 14th example.
and Fig. 15. This product has no recesses on the top surface, has arrows indicating the direction of light projection and wiring on the smooth top surface, and is directly attached to the top surface by layering the pilot plate and protective cover (neither of which are shown). A tool 48, such as a bolt, is screwed into the mounting portion 44 to fix it. The mounting portion 44 is located at a position corresponding to the center of the base and has a mounting hole 42 around the periphery, which is the same as in the previous embodiment. In addition, a screw hole for removal is provided around the periphery and a protective bolt is attached.

Note that the protective equipment 4 may be provided directly with a mark indicating the location direction of the attachment part on the main body.In short, it is attached to the base and its opening is closed, and the top face corresponding to the center of the base is attached. It is sufficient if a mounting part is provided at the position.
The attachment portion is not limited to a screw hole, but may be a bolt or a wedge hole, and in this case, the attachment tool or the pilot shaft may be formed into a screw hole or wedge corresponding to the attachment portion. Additionally, the template may have a painted line around its periphery, as long as it can be marked to indicate how to drill a hole at a predetermined distance from the pilot shaft. You may attach a postcard.
