Description
【発明の詳細な説明】
この発明は地中連続壁の施工法に関するもので、その目
的は地下水の影響を受けることなく容易にしかも完全な
地中壁を構築することができる施工法を提供することに
ある。[Detailed Description of the Invention] This invention relates to a construction method for an underground continuous wall, and its purpose is to provide a construction method that can easily and completely construct an underground wall without being affected by groundwater. There is a particular thing.
一般に地中に連続壁を施工する場合には施工位置を所定
深さまで掘削し、配筋をおこない、コンクリートを充填
して構築されるが、しばしかコンクリートが地下水に流
水して強度上問題があった。Generally, when constructing a continuous wall underground, the construction site is excavated to a predetermined depth, reinforcement is placed, and then filled with concrete. Ta.
この発明は、前記従来の問題点に対処するために提案さ
れたものである。This invention has been proposed to address the above-mentioned conventional problems.
以下図示する実施例により説明すると、掘削孔内に垂直
に配設された縦筋１の外側に格子状鉄筋網２を添接する
。To describe the embodiment shown below, a lattice-like reinforcing bar network 2 is attached to the outside of a vertical bar 1 vertically disposed in an excavated hole.
そして更にこの鉄筋網２の外側を被覆するように、比較
曲目の粗い透水性布よりなるシート３を取付ける。Further, a sheet 3 made of a water-permeable cloth with a relatively coarse curve is attached so as to cover the outside of the reinforcing bar net 2.
次いでシート３内に浸透してくる地下水等の水を汲み上
げ、しかる後シート３内にコンクリートを打設する。Next, water such as groundwater that has permeated into the sheet 3 is pumped up, and then concrete is poured into the sheet 3.
この際シート３は透水性布からなるので、シート３内に
土砂が侵入するのを防止できる。At this time, since the sheet 3 is made of water-permeable cloth, it is possible to prevent dirt from entering the sheet 3.
以上のような操作を順次繰り返し、所定の長さ連続壁を
構築するものである。The above operations are repeated in sequence to construct a continuous wall of a predetermined length.
この発明は以上の構成からなり、シートは透水性の商よ
りなるので、打設されたコンクリートが流出することな
く、僅かにその水分が外部に浸透し、掘削孔壁にシート
が密着することにより、孔壁の崩落を防止しながら施工
することができる。This invention has the above-mentioned structure, and since the sheet is made of water-permeable material, the poured concrete does not flow out, but a slight amount of water permeates to the outside, and the sheet adheres to the wall of the excavation hole. , construction can be carried out while preventing the hole wall from collapsing.
またシート内には地下水等の水が浸透してくるが、スラ
イムは入ってこないので、水を汲み上げることによりス
ライムの影響を受けずに完全にドライな状態でコンクリ
ート打設を行なうことができ、また水を汲み上げること
なく水中コンクリート打設も可能である。In addition, although water such as groundwater permeates into the sheet, slime does not enter the sheet, so by pumping up the water, concrete can be placed in a completely dry state without being affected by slime. It is also possible to place concrete underwater without pumping up water.
そして水を汲み上げる際にシートは掘削孔壁の土庄を受
けるが、鉄筋網、および縦筋によって補強されているの
で、土庄に充分耐えうる。When pumping up water, the sheet is exposed to the soil of the borehole wall, but since it is reinforced with a reinforcing bar net and vertical bars, it can withstand the soil.
