Prefabricated diaphragm wall and construction method thereof
According to the prefabricated underground diaphragm wall and the construction method thereof, the prefabricated part units are prefabricated in a factory, splicing of the prefabricated part units in the horizontal direction is completed through UHPC on the construction site, horizontal connecting joints are plugged in the mode that high-performance concrete is poured and connected with second cavities, the seepage path is prolonged, and the seepage efficiency is improved. Therefore, the connecting component units form a whole, and the anti-seepage performance of the prefabricated diaphragm wall is ensured. In order to facilitate transportation and hoisting, the single diaphragm wall is split in the horizontal direction and the vertical direction, the minimum component units are produced in a prefabricated component factory and then spliced on site, and the first cavities and the second cavities are formed in the prefabricated components, so that the prefabricated components are convenient to transport and hoist. The sectional area can be reduced by pouring concrete in the cavity on site, so that the weight and the size of the component unit are controlled, and the size precision, the pouring quality and the use performance of the underground diaphragm wall can be improved.
本发明提供了一种预制地连墙及其施工方法，本发明的预制构件单元工厂预制，在施工现场使用UHPC完成预制构件单元的水平方向的拼装，水平连接节点采用高性能混凝土浇筑连接第二空腔的方式封堵，延长了渗流路径，从而使连接构件单元形成整体，确保了预制地连墙的抗渗性能。本发明的构件为方便运输和吊装，将单幅地连墙在水平和竖直两个方向进行拆分，在预制构件工厂生产最小构件单元后在现场拼装，并且通过在预制构件内设置第一空腔和第二空腔，可以通过现场在空腔内浇筑混凝土的方式减小截面面积，从而控制构件单元的重量和尺寸，可以提升地下连续墙的尺寸精度、浇筑质量和使用性能。
