REINFORCED SOIL WALL CONSTRUCTION METHOD
To provide a reinforced soil wall construction method capable of suppressing construction cost and days while securing a wall face material safety.SOLUTION: A reinforced soil wall construction method constructs a retaining wall comprising a wall face material at a front face side of a natural ground 20 and reinforces the natural ground 20 by the retaining wall. The wall face material is constituted of a geocell including a plurality of substantially belt-like belt members 5 and a restraining portion 7 restraining a filler. The method comprises: a first step of vertically laminating the plurality of geocells at the front face side of the natural ground 20 to form a first wall portion 3; and a second step of connecting the plurality of geocells in a longitudinal direction from a rear face of the first wall portion 3 toward the natural ground 20 to form a second wall portion 4. In the second step, the filler 12 is thrown into a non-connection part of the belt members 5 of a part of the geocells constituting the second wall portion 4. A separation width of the non-connection part of the belt members 5 of the remaining geocells constituting the second wall portion 4 is adjusted to be a specific width, into which the filler 12 is thrown, then a rear end portion of the geocells are made to be in contact with a front face 23 of the natural ground 20, to be supported in a vertical direction.SELECTED DRAWING: Figure 4
【課題】壁面材の安定性を確保しつつ施工費や施工日数を抑制することができる補強土壁工法を提供する。【解決手段】地山２０よりも前面側に壁面材からなる擁壁を構築し、該擁壁により地山２０を補強する補強土壁工法であって、前記壁面材は、複数の略帯状をなす帯部材５と充填材を拘束する拘束部７を有するジオセルで構成され、地山２０よりも前面側に複数のジオセルを上下に積層して第１壁部３を形成する第１工程と、第１壁部３の後面から地山２０に向け複数のジオセルを前後に連設して第２壁部４を形成する第２工程とを備え、前記第２工程において、第２壁部４を構成する一部のジオセルの帯部材５同士の非接合部位に充填材１２を投入するとともに、第２壁部４を構成する残りのジオセルの帯部材５同士の非接合部位の離間幅を特定幅に調整して充填材１２を投入した後、ジオセルの後端部を地山２０の前面２３に当接させることで鉛直方向に支持させる。【選択図】図４
