Prestress assembly type underground diaphragm wall and construction method thereof
The invention discloses a prestress assembly type underground diaphragm wall which comprises unit walls I and unit walls II which are alternately connected to form an annular structure or a polygonal structure in a surrounding manner, the adjacent ends of the unit walls I and the unit walls II are paired with each other to form closed cavities, and concrete is poured into the closed cavities so that the unit walls I and the unit walls II can be connected and fixed; the unit walls I and the unit walls II are each of a box type structure internally provided with a cavity, and reinforcement cage structures are embedded in the box type structures; and each reinforcement cage structure comprises steel bars I transversely arranged on the transverse portion of the corresponding box type structure, steel bars II vertically arranged on the transverse portion and the longitudinal portion of the corresponding box type structure, tie bars used for hooping parts of the steel bars II in the transverse portion and stirrups I used for hooping the steel bars II at the corresponding positions of the vertical portion. By means of the arrangement, the underground diaphragm wall is good in water resistance property, construction is simple, and connection is reliable.
本发明公开了一种预应力装配式地下连续墙，包括交替相连以围覆形成环状结构或多边形结构的单元墙Ⅰ和单元墙Ⅱ，单元墙Ⅰ和单元墙Ⅱ的相邻端相互配对形成封闭腔,通过在封闭腔内浇筑混凝土以将单元墙Ⅰ和单元墙Ⅱ连接固定，单元墙Ⅰ和单元墙Ⅱ采用内设有空腔的箱型结构，箱型结构内埋有钢筋笼结构，钢筋笼结构包括横向排列于箱型结构的横向部的钢筋Ⅰ、竖向排列于箱型结构的横向部和纵向部的钢筋Ⅱ、用于箍紧横向部内的部分钢筋Ⅱ的拉筋和用于箍紧竖向部对应位置的钢筋Ⅱ的箍筋Ⅰ，通过上述设置，该地下连续墙防水性能好，施工简单，连接可靠。
