JP 2003-171922 A

  By the way, according to the revetment structure of the above-mentioned patent document 1, since a plurality of revetment members are individually provided, at the time of construction work of the revetment, by filling the inner space of each bag-like body, respectively, Each of the revetment members needs to be individually molded. Therefore, the construction work of the revetment may be extremely complicated.

  In addition, there is a connecting material between the revetment members adjacent to each other on the slope, and each portion of the shore corresponding to each connecting material is not sufficiently covered. There is a risk of scouring in a short period of time due to waves. Therefore, the above-mentioned Patent Document 1 is not always satisfactory in obtaining a preferable revetment that keeps the shore in a predetermined shape for a long time.

  Therefore, it is conceivable that the covering material is composed of a solidified soil that covers the entire slope, but since such a solidified soil generally has fluidity, the slope is steep. Even so, the revetment constructed with the solidified soil tends to have a gentle gradient due to the flow of the solidified soil due to its own weight. As a result, an unnecessarily large amount of the solidified soil used for the construction of the revetment is required, and accordingly, the construction work of the revetment becomes extremely complicated, and a large amount of cement is used for the solidified soil. The construction cost becomes expensive.

The present invention has been made by paying attention to the above-described circumstances, and an object of the present invention is to make it easy to construct a revetment and to provide a preferable revetment that can keep the shore in a predetermined shape over a long period of time. Ru der be obtained way.

The invention of claim 1 is a revetment construction method for covering an inclined slope 2 on the shore 1 with a covering material 3,
The covering material 3 has a plurality of revetment sheets 4 provided in the horizontal direction A along the slope 2, and these revetment sheets 4 face each other in a direction B perpendicular to the slope 2, and The lower edges 6 in the inclined direction C along the surface 2 are coupled to each other, and the lower sheets 7 and 8 are provided, and the upper and lower sheets 7 and 8 that are adjacent in the horizontal direction A are opposed to each other. The edge portions 18 and 18 are connected to each other, and provided with a reinforcing belt 10 that is fixed to the opposite edge portions 18 and 18 and reinforces the upper and lower sheets 7 and 8. A plurality of hooking belts 14 projecting upward from the respective upper edge portions 13 of the sheets 7 and 8 are provided, and a pair of upper and lower support pipes 26 are fixed to the shore 1 and extended in the horizontal direction A in the vertical direction B. , 26 to each of the above-mentioned retaining belts 14 Allowed, communicated with each other an interior space 19 of each shore protection sheet 4,
And between the pair of upper and lower support pipes 26 and 26, on the in the inclined direction C, through the opening 25 between each of the upper edges 13, 13 of the lower sheet 7,8, outside of the seawall sheet 4 To filling the internal space 19 with the filler 20 .

  In this section, the reference numerals appended to the above terms are not intended to limit the technical scope of the present invention to the contents of the “Examples” section described later.

Effect according to the present invention, Ru der as follows.

Invention of Claim 1 is the construction method of the revetment which coat | covers the inclined slope in a shore with a coating | covering material,
The covering material has a plurality of revetment sheets provided in a horizontal direction along the slope, and these revetment sheets face each other in a direction perpendicular to the slope, and in an inclined direction along the slope. The lower edges of the upper and lower sheets are connected to each other and connected to each other in the horizontal direction, and the opposite edges of the lower sheet are connected to each other, and are fixed to the opposite edges. A reinforcing belt for reinforcing the upper and lower sheets is provided, and a plurality of hooking belts protruding upward from the respective upper edge portions of the upper and lower sheets in the inclined direction are provided, fixed to the shore, and The hooking belts are hooked on a pair of upper and lower support pipes in the vertical direction extending in the horizontal direction, and the internal spaces of the bank protection sheets are communicated with each other.
And between the upper and lower pair of support pipes, on the in the inclined direction, through an opening between the upper edge of the lower sheet, are filled with a filler to the internal space from the outside of the seawall sheet The

For this reason, since the revetment sheets of the covering material are connected to each other and their internal spaces communicate with each other, the fillers filled in the internal spaces are integrated with each other. Therefore, it is not necessary to individually fill and form the filler for each revetment sheet at the time of revetment construction work, and the revetment construction work can be facilitated accordingly.

Further, as described above, the revetment sheets of the covering material are coupled to each other, the internal spaces of these revetment sheets communicate with each other, and the internal space is filled with the filler and integrated with each other, The slope is covered more entirely by the covering material. Therefore, it is more reliably prevented that the shore is eroded or scoured by waves, and a more preferable revetment is obtained.

In addition, when filling the interior space of each revetment sheet laid on the slope, it is only necessary to fill the filler through the opening. The space naturally flows down (including drops) by its own weight, and is filled over a wide area in these internal spaces. Therefore, since the filling work of each internal space can be facilitated, the construction work of the revetment can be facilitated.

  The best mode for carrying out the present invention is as follows in order to realize the purpose of making the revetment construction work easy and obtaining sufficient revetment for the revetment structure of the present invention. It is like this.

  That is, a covering material is provided that extends along the sloped slope on the shore and covers the slope. This covering material has a revetment sheet provided in a plurality in the horizontal direction along the slope. Each of these revetment sheets faces each other in a direction perpendicular to the slope, and has a lower sheet in which lower edge portions in an inclined direction along the slope are integrally coupled to each other. The opposite edge portions of the upper and lower sheets adjacent to each other in the horizontal direction are connected to each other, and the revetment sheets are connected to each other, and the internal spaces of the revetment sheets are communicated with each other, The space is filled with a filler containing a solidifying material such as cement.

  In order to explain the present invention in more detail, an embodiment thereof will be described with reference to the accompanying drawings.

  The figure shows a revetment structure. In the figure, reference numeral 1 is a shore where a revetment is to be constructed, and 2 is an inclined slope on this shore 1.

  A covering material 3 extending along the slope 2 and covering the slope 2 is provided. The covering material 3 has a revetment sheet 4 having a high strength and excellent weather resistance and water resistance provided in the horizontal direction A along the slope 2.

  The revetment sheets 4 face each other in the direction B perpendicular to the slope 2 and have water permeability in which the lower edge portions 6 in the inclined direction C along the slope 2 are integrally coupled to each other. The upper and lower sheets 7 and 8 and the upper and lower sheets 7 and 8 in the horizontal direction A are fixed to the respective edge portions 9 and midway of the upper and lower sheets 7 and 8 by welding or stitching. The upper and lower sheets 7 and 8 in the vertical direction B so as to prevent the respective parts of the upper and lower sheets 7 and 8 from separating from each other by a predetermined dimension or more. A plurality of connecting bodies 11 made of rope to be connected to each other, and a plurality of hooking belts 14 protruding upward from the upper edge portions 13 of the upper and lower sheets 7 and 8 in the inclined direction C. Yes.

  The upper and lower sheets 7 and 8 are formed by folding a long sheet in the middle in the longitudinal direction, and substantially U-shaped along the inclined direction C as viewed from the line of sight along the horizontal direction A. The upper and lower sheets 7 and 8 as a whole extend in the inclined direction C as a whole.

  Each reinforcing belt 10 is provided over substantially the entire length of the upper and lower sheets 7 and 8. Further, holes 16 are formed in the reinforcing belt 10 at substantially equal pitches along the longitudinal direction thereof. Each connecting body 11 is inserted through the hole 16 and firmly connects the upper and lower sheets 7 and 8 so as to embrace the portions of the reinforcing belts 10 fixed to the lower sheets 7 and 8. Further, the base portion of each of the hooking belts 14 is firmly fixed to the fixing portion between the upper and lower sheets 7 and 8 and the reinforcing belt 10.

  The opposite edge portions 18 and 18 of the upper and lower sheets 7 and 8 that are adjacent in the horizontal direction A are overlapped with each other in the vertical direction B and connected by welding, stitching, or the like. The spaces 19 are communicated with each other. Each of the opposing edge portions 18 corresponds to the end edge portion 9. Each internal space 19 is filled with a filler 20. The filler 20 is, for example, a mixture of clay 22 and cement 23, and the filler 20 is in a paste form when filling the internal space 19, but is then solidified by the action of the cement 23. .

  Between the upper edge portions 13 and 13 of the upper and lower sheets 7 and 8 in the inclined direction C, an opening 25 is formed to communicate the inner space 19 with the inside and outside of the revetment sheet 4. 25, the filler 20 can be filled into the internal space 19 from the outside of the revetment sheet 4. The opening 25 is formed over substantially the entire revetment sheet 4 in the horizontal direction A.

  Next, the construction method of the revetment will be described.

  When building a revetment by the above method, first, a revetment sheet 4 is laid on the slope 2 of the shore 1. In this case, the upper and lower sheets 7, 8 are placed on the slope 2. May be laid while being sequentially joined in the horizontal direction A, or those previously joined at the factory may be laid on the slope 2.

  Next, a support pipe 26 extending in the horizontal direction A is installed in the upper region above the slope 2 and fixed to the shore 1. And the said revetment sheet | seat 4 is prevented from sliding down the inclination direction C along the slope 2 by latching the said retaining belt 14 on the said support pipe 26. FIG.

  Next, the clay 22 and the cement 23 are sucked by the fluid pump 27 and mixed to form the filler 20, while the filler 20 is passed through the opening 25 by the pump 27 and inside the revetment sheet 4. The space 19 is filled. In this case, the connecting body 11 prevents the upper and lower sheets 7 and 8 from separating more than a predetermined amount due to the pressure of the filler 20. A covering material 3 is laid on the slope 2 and the slope 2 is covered with the covering 3. When the filler 20 is solidified by the action of the cement 23, the revetment construction work is completed.

  According to the said structure, the coating | covering material 3 has the revetment sheet 4 provided with two or more by the horizontal direction A along the said slope 2, and each of these revetment sheets 4 mutually faces in the perpendicular direction B with respect to the said slope 2 In addition, the lower edge portions 6 in the inclined direction C along the slope 2 are coupled to each other, and the lower sheets 7 and 8 are provided, and the upper and lower sheets 7 and 8 that are adjacent in the horizontal direction A are respectively provided. The opposing edge portions 18 and 18 are connected to each other so that the internal spaces 19 of the revetment sheets 4 communicate with each other, and the internal spaces 19 are filled with a filler 20.

  For this reason, since the revetment sheets 4 of the covering material 3 are connected to each other and the internal spaces 19 communicate with each other, the fillers 20 filled in the internal spaces 19 are integrated with each other. The Therefore, it is not necessary to individually fill and form the filler 20 for each of the revetment sheets 4 during construction of the revetment, and accordingly, the revetment construction work can be facilitated.

  Further, as described above, the revetment sheets 4 of the covering material 3 are coupled to each other, the internal spaces 19 of the revetment sheets 4 communicate with each other, and the internal spaces 19 are filled with the filler 20 to be integrated with each other. Therefore, the slope 2 is more entirely covered with the covering material 3. Therefore, the shore 1 being eroded or scoured by waves can be more reliably prevented by the covering material 3, and a more preferable revetment can be obtained.

  In particular, if a material having water barrier properties such as mixed soil obtained by mixing cement with clay and the like is used for the filler 20 described above, a water barrier can be constructed. In this way, it is possible to construct a landfill revetment for a waste disposal site where both more preferable revetment and water shielding are strongly required.

  Further, as described above, the connecting body 11 for connecting the respective parts of the upper and lower sheets 7 and 8 to each other so as to prevent the respective parts of the upper and lower sheets 7 and 8 from separating from each other by a predetermined size or more. I have.

  For this reason, since the maximum capacity of the internal space 19 of each revetment sheet 4 of the said covering material 3 is determined to some extent by the said coupling body 11, when the filler 20 is filled into the internal space 19 of each said revetment sheet 4 Even if the filler 20 has fluidity, the filling amount of the filler 20 into the internal space 19 is limited to correspond to the maximum capacity.

  Therefore, it is prevented that the filler 20 in the covering material 3 is unnecessarily large in quantity, and the amount of the filler 20 is suppressed to an appropriate amount that can be planned. It becomes easier and the construction cost is lower.

  Further, as described above, the opposed edge portions 18 and 18 coupled to each other are overlapped with each other in the vertical direction B.

  For this reason, it is prevented that a clearance gap arises between the opposing edge parts 18 and 18 of the upper sheet | seat 7 and 8 which adjoin each other in the said horizontal direction A, respectively. Therefore, when the inner space 19 of each revetment sheet 4 is filled with the filler 20, it is prevented that a part of the filler 20 leaks from between the opposing edge portions 18, 18. Therefore, construction work of the above revetment will be easier.

  Moreover, since the opposing edge portions 18 are overlapped with each other as described above, the coupling between the opposing edge portions 18 can be strengthened, and a more preferable bank protection is obtained accordingly.

  In addition, as described above, an opening 25 is formed between the upper edge portions 13 and 13 of the upper and lower sheets 7 and 8 in the inclination direction C, and the opening 25 is passed through from the outside of the revetment sheet 4. The internal space 19 can be filled with the filler 20.

  For this reason, when filling the filler 20 into the internal space 19 of each revetment sheet 4 laid on the slope 2, it is only necessary to fill the filler 20 through the opening 25. In this way, The filler 20 naturally flows down in the internal spaces 19 by its own weight, and is filled over a wide area in the internal spaces 19. Therefore, since the filling work of the filler 20 into each internal space 19 can be easily performed, the construction work of the revetment can be easily performed.

  Further, as described above, the opening 25 is formed over substantially the entire revetment sheet 4 in the horizontal direction A.

  For this reason, the filling of the filling material 20 into each internal space 19 through the opening 25 can be performed at each part in the horizontal direction A of the revetment sheet 4, and thus the filling material 20 into the respective internal space 19 can be filled. Since there is no restriction on the filling position, the degree of freedom in filling the inner space 19 with the filling material 20 is improved, and in this respect also, the construction work of the revetment structure becomes easier.

  In addition, although the above is based on the illustrated example, the revetment sheet 4 may be formed by mutually fixing the lower edge portions 6 and 6 of the lower sheets 7 and 8 to each other and forming the revetment sheet 4. It may be. Further, the connecting body 11 may be a belt, a wire, a chain, a wire, or the like. The filler 20 may contain pebbles, sand, sludge and the like.

It is a partial perspective view of a seawall structure. It is a partially broken side sectional view of the revetment structure. FIG. 3 is a cross-sectional view taken along line 3-3 in FIG. 1. FIG. 4 is a sectional view taken along line 4-4 in FIG. 3.
