More Information
Summary:The invention relates to a construction method of a civil air defense building engineering reverse construction method meeting a thick water-containing sand layer, which comprises the following steps: firstly, paying off and positioning, then constructing a support pile, pouring an underground diaphragm wall around a building as an enclosure wall of a foundation pit support structure, drilling according to a pile position, and then lowering a first reinforcement cage; and in the process of lowering the first reinforcement cage, a prefabricated connecting piece is installed on the first reinforcement cage, then concrete is poured to form a supporting pile, and ring beam construction and floor slab construction are conducted in sequence. The connecting structure has the effect of improving the connecting strength of the structural beam and the supporting piles. 本申请涉及一种人防建筑工程逆作法遇厚层含水沙层施工方法，首先进行放线定位，接着进行支撑桩施工，沿建筑物周围浇注地下连续墙，作为基坑支护结构的围护墙，并根据桩位进行钻孔，然后下放第一钢筋笼，下放第一钢筋笼的过程中在第一钢筋笼上安装预制连接件，之后浇筑混凝土以形成支撑桩，依次进行环梁施工和楼板施工。本申请具
