Construction method of diaphragm wall of underground facility
The invention discloses a construction method of a diaphragm wall of an underground facility. According to the technical scheme, the construction method comprises the following steps: constructing diaphragm walls on the two sides of the far end of a cable trench; forming a trench below the cable trench, and constructing diaphragm walls on the two sides of the cable trench; underpinning undergroundfacilities and excavating auxiliary foundation pits; manufacturing and installing a local prefabricated guiding wall, installing a segmented reinforcement cage positioning device and manufacturing and installing a reinforcement cage guiding device; conveying the segmented reinforcement cage positioning device to the position above the guiding device, lowering a segmented reinforcement cage; and erecting a diaphragm wall formwork, and pouring concrete. The segmented reinforcement cage is transported, so that convenience is provided for installation of the reinforcement cage; and the strength and rigidity of the diaphragm wall after construction can be guaranteed.
本发明公开了一种地下设施下地连墙施工方法，其技术方案为：包括：施工电缆沟远端两侧地连墙；成槽电缆沟以下沟槽，施工电缆沟两侧地连墙；托换地下设施，开挖辅助基坑；制作并安装局部预制导墙，安装分节钢筋笼就位装置，制作并安装钢筋笼导正装置；分节钢筋笼经就位装置运输至导正装置上方，下放分节钢筋笼；支设地连墙模板，并浇筑混凝土。本发明通过运输分节钢筋笼，为钢筋笼安装提供了便利；能够保证施工后地下连续墙的强度及刚度。
