EARTH RETAINER WALL AND CONSTRUCTION METHOD OF EARTH RETAINER WALL BY BERLINOISE METHOD
PROBLEM TO BE SOLVED: To provide an earth retainer wall which can be constructed more simply and sufficiently exert water barrier efficiency when a ground water level at an earth retainer construction field is a level higher than an excavation bottom, and a construction method of the earth retainer wall by berlinoise method.SOLUTION: There is provided an earth retainer wall applied to ground having an aquifer 3 surrounded by water impermeable layers 4 at both upper and lower sides, which comprises a series of soldier spiles 12 established in a line on the ground and wall bodies 20 formed between adjacent soldier spiles. Each wall body comprises lateral spiles 22 established between the soldier spiles in a manner where they expose to a digging part formed on the front side of the wall body and a back layer 24 formed on the backside of the lateral spiles and the ground in a situation where it contacts to the backside. The back layer is formed at a site contacting to at least the aquifer. At the site, a water barrier wall part 26 is formed by mixing back soil with a water barrier material. The water barrier wall part covers approximately the entire dug surface of the aquifer.SELECTED DRAWING: Figure 1
【課題】山留め工事の現場の地下水位が根切り底より高いレベルにあるときに、より簡易に構築できかつ遮水性能を十分に発揮できる山留め壁及び親杭横矢板工法による山留め壁の構築方法を提供する。【解決手段】上下両側の不透水層４で挟まれた帯水層３を含む地盤に適用される山留め壁であって、上記地盤中に一列に建て込まれた一連の親杭１２と、隣り合う親杭同士の間に形成される壁体２０とを具備する。各壁体は、それら親杭の間に、前記壁体の表面側に形成される掘削部に露出するように架設させた横矢板２２と、上記横矢板の裏面に密接させた状態で当該裏面と地盤とに形成された裏込め層２４とを有している。この裏込め層は、少なくとも帯水層に接する箇所に形成されており、当該箇所において、裏込め土に遮水材料を混入させてなる遮水壁部２６としており、この遮水壁部が帯水層の被掘削面の略全体を覆う。【選択図】図１
