Semi-prefabricated underground diaphragm wall structure and construction method thereof
The invention discloses a semi-prefabricated underground diaphragm wall structure and a construction method thereof, and relates to the technical field of underground enclosure structures, the semi-prefabricated underground diaphragm wall structure comprises a plurality of diaphragm wall units which are sequentially connected, a groove is formed in the ground in the vertical direction, guide walls are arranged at the upper ends of the two opposite side walls of the groove, and the plurality of diaphragm wall units are sequentially arranged in the length direction of the groove; each continuous wall unit comprises a prefabricated wall body arranged at the bottom of the groove, a steel bar frame arranged on the outer side of the prefabricated wall body, a steel bar cage arranged at the upper end of the steel bar frame and a concrete layer filled in the groove, and the steel bar frame and the steel bar cage are wrapped in the concrete layer; the steel bar frame comprises a hanging plate and two rows of steel meshes arranged at the lower end of the hanging plate, the steel meshes cover gaps between the adjacent prefabricated wall bodies, clamping grooves are formed in the lower ends of the two opposite sides of the prefabricated wall bodies in the length direction of the prefabricated wall bodies, and the clamping grooves between the adjacent prefabricated wall bodies are communicated. The prefabricated wall has the effect that the water seepage possibility of the gap between the adjacent prefabricated walls can be effectively reduced.
本发明公开一种半预制地下连续墙结构及其施工方法，涉及地下围护结构的技术领域，包括若干依次相连的连续墙单元，在地面上沿竖直方向开设有凹槽，凹槽相对两侧壁上端均设置有导墙，若干连续墙单元均沿凹槽长度方向依次设置，连续墙单元均包括设置在凹槽底部的预制墙体、设置在预制墙体外侧的钢筋架、设置在钢筋架上端的钢筋笼以及填充于凹槽的混凝土层，钢筋架、钢筋笼包覆于混凝土层内；钢筋架包括吊板以及分别设置在吊板下端的两排钢网片，钢网片遮盖相邻预制墙体之间缝隙，预制墙体相对两侧下端均沿预制墙体长度方向开设卡槽，相邻预制墙体之间卡槽连通。本申请具有可有效降低相邻预制墙体之间缝隙渗水可能的效果。
