Construction technology of underground diaphragm wall serving as underground core tube permanent structure
The invention relates to a construction technology for an underground diaphragm wall serving as an underground core tube permanent structure, and belongs to the field of underground diaphragm wall construction technologies. The method comprises the steps that S1, according to the design construction position of a core tube structure wall, four sections of L-shaped pit slots in a rectangular frame shape are excavated through excavating equipment; s2, L-shaped reinforcement cages are prefabricated, and the four reinforcement cages can be spliced into a rectangular barrel matched with the pit slots; s3, reinforcement cages are hoisted and placed in the pit slot, the reinforcement cages are installed at the four corners of the pit slot, and a post-cast strip is reserved between every two adjacent reinforcement cages; s4, concrete is poured into the pit slot and located at the position of the reinforcement cage, four L-shaped underground diaphragm walls are formed, and a connecting piece is arranged at the end of each underground diaphragm wall; s5, a top beam and a top plate are arranged at the top of the diaphragm wall; and S6, after the foundation earth is excavated, the underground diaphragm wall is connected with the horizontal ribs of the post-cast strip through the connecting pieces, and concrete is poured at the post-cast strip. The method has the effect of shortening the construction period.
本申请涉及一种地下连续墙兼做地下核心筒永久结构的施工工艺，属于地下连续墙施工技术的领域。其包括S1：根据核心筒结构墙体的设计施工位置，通过挖掘设备开挖呈矩形框的四段L型坑槽；S2：预制呈L形的钢筋笼，四个钢筋笼可拼接为与坑槽相适配的矩形筒体；S3：将钢筋笼吊装放置于坑槽中，坑槽四角处均安装有钢筋笼，相邻钢筋笼之间预留后浇带；S4：向坑槽中且位于钢筋笼处浇筑混凝土，形成四幅L形地连墙，在每幅地连墙的端部均设置有连接件；S5：在地连墙顶部设置冠梁以及顶板；S6：待地基土方开挖后，将地连墙通过连接件与后浇带的水平筋相连接，并在后浇带处浇筑混凝土。本申请具有缩短施工周期的效果。
