【従来技術】[Prior art]

従来、建築又は土木工事において、擁壁を構築する際に、擁壁の裏面に砂利や 砕石等により透水層を形成し、擁壁の裏面の排水を効果的に行なえるようにする ことが義務づけられている。 Conventionally, when building a retaining wall in construction or civil engineering, it has been obligatory to form a permeable layer on the back side of the retaining wall with gravel or crushed stone so that the back side of the retaining wall can be effectively drained. Has been.

【0003】 しかし、近年、良質な石材の枯渇や運搬費用の高騰等により、砂利や砕石を大 量に入手するのが困難となっている。 そのため、砂利や砕石に代えて、合成樹脂材料や不織布その他の材料よりなる 人工の透水マットを擁壁の裏面の透水層として用いることが研究され、すでに一 定の基準を満たすものについては使用が許可される状況となっている。However, in recent years, it has become difficult to obtain a large amount of gravel and crushed stone due to depletion of high-quality stone materials and soaring transportation costs. Therefore, instead of gravel or crushed stone, research has been conducted to use an artificial water-permeable mat made of synthetic resin material, non-woven fabric, or other material as the water-permeable layer on the back surface of the retaining wall. It is in a situation where it is permitted.

【考案が解決しようとする課題】[Problems to be solved by the device]

しかし、上述のような透水マットを擁壁の裏面に取付ける具体的な手段につい ては未だ十分な研究がなされておらず、単にくぎ止めするか、接着剤により接着 する程度のことしか考えられていないのが現状である。 However, sufficient research has not yet been conducted on the specific means of attaching the above-mentioned water-permeable mat to the back surface of the retaining wall, and it has only been considered that it is simply nailed or bonded with an adhesive. The current situation is that there are none.

【0005】 本考案は、こような点に鑑み、擁壁への透水マットの取付け作業を、熟練を要 することなく、迅速かつ確実に行なうことができ、しかも修正作業を簡単に行な うことができるようした擁壁への透水マットの取付け構造を提供することを目的 としている。In view of the above points, the present invention can quickly and surely perform the work of attaching the water-permeable mat to the retaining wall without requiring skill, and can easily perform the correction work. The purpose of the present invention is to provide a mounting structure for a water-permeable mat to a retaining wall that is capable of doing so.

The water-permeable mat (A) may have any constitution other than at least one surface material, but in this embodiment, a large number of convex short cylinder-shaped convex portions (13) and a short cylinder with a bottom are provided on both front and back surfaces. The concave-convex sheet (15) made of a synthetic resin material, in which a large number of concave portions (14) are arranged alternately in both vertical and horizontal directions, is used as the base material, and the bonding piece (12) is attached as a surface material on one side It is as worn. (15a) is a water passage hole formed in the top surface (or the bottom surface of the concave portion (14)) of the appropriate convex portion (13) of the uneven sheet (15).

【0013】 しかし、透水マット(A)を、図4に示すように、基材である凹凸シート(15)の 表裏両面に、接合片(12)を表面材として貼着したものとしたり、図5に示すよう に、基材として、複数の網板(16)を重ね合わせたものを用い、その周囲を接合片 (12)により、その接合面(12a)が外側を向くようにして被包するとともに、それ らの適所をピン(17)又はワイヤ等をもって止着したものとしたり、図示は省略し たが、基材を合成樹脂製の波板又は不織布等としてもよい。However, as shown in FIG. 4, the water-permeable mat (A) may be obtained by attaching the joining pieces (12) as surface materials to both the front and back surfaces of the uneven sheet (15) which is a base material. As shown in Fig. 5, a plurality of mesh plates (16) are used as a base material, and the periphery thereof is covered with a bonding piece (12) so that the bonding surface (12a) faces outward. In addition, the appropriate places thereof may be fixed with pins (17) or wires, or the base material may be a corrugated sheet or a non-woven fabric made of synthetic resin, although not shown.

【0014】 このようにして形成した透水マット(A)の接合面(2)を上述のようにして擁壁 (3)の裏面に予め固着しておいた接合片(9)の接合面(9a)に押し付けると、両接 合面(9a)(12a)の線材(8)(11)同士が互いに噛合し、透水マット(A)は迅速にか つ確実に擁壁(3)に取付けられる。The joint surface (2) of the water-permeable mat (A) thus formed is fixed to the rear surface of the retaining wall (3) in advance as described above. ), The wire rods (8) and (11) of the contact surfaces (9a) and (12a) are meshed with each other, and the water permeable mat (A) is quickly and surely attached to the retaining wall (3).

【0015】 また、透水マット(A)の取付け位置を誤ったり、又は修正したい場合には、透 水マット(A)を少し強い力で擁壁(3)から引き剥がすことができ、また正規の位 置に簡単に再接着させることもできる。When the mounting position of the water permeable mat (A) is wrong or it is desired to correct it, the water permeable mat (A) can be peeled off from the retaining wall (3) with a little strong force, and a regular It can also be easily reattached to the position.

【0016】 透水マット(A)を擁壁(3)に取付けた後、高地盤(1)側の土砂を埋め戻せば、 擁壁工事は完了し、擁壁(3)の裏面と高地盤(1)側の土砂との間、特に凹凸シー ト(15)の擁壁(3)側の面の凸部間に、上下、左右及び前後方向の通水路(図示略) が形成され、そこを通った地中水は、水抜孔(4)より排水される。After mounting the water-permeable mat (A) on the retaining wall (3), if the soil on the high ground (1) side is backfilled, the retaining wall construction is completed, and the back surface of the retaining wall (3) and the high ground ( Water channels (not shown) are formed in the vertical, horizontal, and front-back directions between the soil on the 1) side, especially between the convex portions of the surface of the uneven sheet (15) on the retaining wall (3) side. The underground water that has passed through is drained from the drain hole (4).

【考案の効果】[Effect of the device]

本考案によると、次のような効果を奏することができる。 (a) 擁壁の裏面に予め固着しておいた面ファスナの一方の接合片に、透水マッ トを軽く押しつけるだけで、透水マットを、熟練を要することなく、迅速かつ確 実に擁壁に取付けることができる。 (b) 万一、透水マットの取付け位置を誤った場合には、透水マットを少し強い 力で引き剥がし、再度位置を変えて簡単に取付け直すことができる。すなわち修 正作業が簡単である。 (c) 両接合片が互いに接合した状態で接合面に沿う方向に若干のずれを許容で きるので、透水マットの局部に掛った応力を分散させることができ、全体として 大きな剥離強度を得ることができる。すなわち、局部から剥れるおそれが少ない 。 According to the present invention, the following effects can be achieved. (a) The permeable mat can be attached to the retaining wall quickly and accurately without requiring any skill by simply pressing the permeable mat against one joint piece of the hook-and-loop fastener that has been fixed in advance on the back surface of the retaining wall. be able to. (b) If the permeable mat is installed in the wrong position, the permeable mat can be peeled off with a little strong force, repositioned, and easily installed again. That is, the repair work is easy. (c) Since both the joining pieces can allow a slight deviation in the direction along the joining surface in the state where they are joined to each other, the stress applied to the local part of the water-permeable mat can be dispersed, and a large peel strength can be obtained as a whole. You can In other words, there is little risk of peeling from the local area.
