In this embodiment, the overall configuration of the disposal site 142 is the same as that of the disposal site 10 of the first embodiment, but an adhesive tape 144 as an adhesive member is disposed between the fixture 140 and the waterproof sheet 18. This is different from the first embodiment. The adhesive tape 144 has a long shape similar to the fixture 140, has a length substantially the same as the fixture 140, and a width substantially the same as or narrower than the fixture 140. In this embodiment, since the waterproof sheet 18 is fused to the fixture 140 by the adhesive tape 144, the fixture 140 does not need to be made of a thermoplastic resin (of course, even if it is made of a thermoplastic resin). no problem).

  Thus, by using the adhesive tape 144 disposed between the fixture 140 and the waterproof sheet 18, it is not necessary to use, for example, a thermoplastic resin or a heat-meltable resin as the fixture 140. The width expands.

  In any embodiment of the present invention, a fixture is disposed on the vertical surface 16B, and the waterproof sheet 18 is firmly attached using the vertical surface 16B. For this reason, compared with the structure which attached the waterproof sheet 18 using only the top end surface 16A of the concrete layer 16, the load which acts on the waterproof sheet 18 can be disperse | distributed.

  For example, in Comparative Example 1 shown in FIG. 13A, anchor bolts 162 are driven into the top end surface 16A of the concrete layer 16 and the waterproof sheet 18 is attached via the flat bar 164. Further, in Comparative Example 2 shown in FIG. 13 (B), a concave portion 166 is formed on the top end surface 16A of the concrete layer 16, and a waterproof sheet 18 is partially disposed in the concave portion 166 near the upper end to fix the concrete from above. The waterproof sheet 18 is attached by embedding in the work 168.

  On the other hand, in each embodiment of this invention, the load which acts on the waterproof sheet 18 can be disperse | distributed by the support by the vertical surface 16B. In the example shown in FIG. 1 and FIG. 12, the waterproof sheet 18 is also attached to the top end face 16A of the concrete layer 16, but it can be omitted and supported only on the vertical face 16B. Moreover, even when the structure for fixing the waterproof sheet 18 on the top end surface 16A is used in the same manner as in Comparative Example 1 and Comparative Example 2, the structure for fixing on the top end surface 16A can be a simple configuration. For example, when the structure shown in FIG. 13A is employed, it is possible to reduce the thickness of the flat bar 164 and reduce the diameter of the anchor bolt 162. When the structure shown in FIG. 13B is employed, the size of the concrete fixing work 168 can be reduced.

The present invention will be described in more detail with reference to examples. The present invention is not limited to the following examples.
In this example, in the wall waterproof structure of the first embodiment, a shear test was performed under the following conditions in order to confirm the fusion strength between the fixture 20 and the waterproof sheet 18.
The material of the fixture 20: LDPE
Material of waterproof sheet 18: LDPE
Test method: JIS K 6850 compliant (Tensile speed: 50 mm / min)
Fixing width: 4cm, 5cm

表１において、「遮水材料特性の目安」とは、社団法人 全国都市清掃会議より発刊された「廃棄物最終処分場整備の計画・設計要領」に示されている、遮水材料の融着部強度特性の目安である。この「廃棄物最終処分場整備の計画・設計要領」は、廃棄物最終処分場の建設に係る自治体職員、コンサルタント、建設企業、遮水材料メーカー等に活用され、最終処分場建設に役立てられているものである。 The test results are shown in Table 1.

In Table 1, “Guidelines for water-blocking material characteristics” refers to the fusion of water-blocking materials shown in “Guidelines for Planning and Design of Final Waste Disposal Sites” published by the National Urban Cleanup Council. This is a guide for strength characteristics. This “Guidelines for Planning and Design of Final Waste Disposal Sites” is used by local government officials, consultants, construction companies, water shielding material manufacturers, etc. for construction of final waste disposal sites, and is used to construct final disposal sites. It is what.

As can be seen from Table 1, when the obtained test data is compared with “Guidelines for water shielding material properties”, the values are much higher than the standard values.
The actual strength can be obtained by multiplying the shear strength by the fixing width, and the strength value is preferably approximately 690 N or more. This value is not reached when the fixing width is 4 cm, but exceeds this value when the fixing width is 5 cm. Therefore, the fixing width is preferably 5 cm or more. Of course, this fixing width does not exceed the width of the fixture 20.
