Construction method of profile steel cement soil stirring wall and enclosure structure
The invention belongs to the technical field of foundation pit engineering construction, and discloses a construction method of a profile steel cement soil stirring wall and an enclosure structure. The construction method of the section steel cement soil stirring wall comprises the steps that multiple sets of holes are drilled in the ground in the first horizontal direction, cement paste is sprayed, and each set comprises multiple holes sequentially arranged in the second horizontal direction; mounting a guide frame in the hole; the multiple pieces of first section steel are mutually connected in the second horizontal direction to form section steel sections; controlling the section steel sections on the first layer to be inserted into the guide frame, and descending the section steel sections to a preset position to be fixed with the guide frame; connecting the profile steel sections of the second layer with the profile steel sections of the first layer, and continuing to lower the profile steel sections of the first layer and the second layer; by parity of reasoning, the multiple layers of profile steel sections are inserted into one set of holes at the same time; and multiple layers of profile steel sections are inserted into the multiple groups of holes according to the steps. According to the depth of a foundation pit, multiple pieces of first section steel can be combined, so that the section steel cement soil stirring walls with different depths and different thicknesses are obtained.
本发明属于基坑工程施工技术领域，公开了一种型钢水泥土搅拌墙的施工方法及围护结构。型钢水泥土搅拌墙的施工方法包括：在地面沿第一水平方向钻设多组孔洞并喷射水泥浆，每组中包括多个沿第二水平方向依次排列的孔洞；在孔洞安装导向架；将多个第一型钢材沿第二水平方向相互连接构成型钢节；再控制第一层的型钢节插入导向架，并将其下降至预设位置与导向架固定；将第二层的型钢节与第一层的型钢节连接，继续下放第一层的型钢节和第二层的型钢节；以此类推将多层型钢节同时插放至一组孔洞内；按照上述步骤在多组孔洞内均插放多层型钢节。本发明可根据基坑深度，将多个第一型钢材进行组合，以得到不同深度以及不同厚度的型钢水泥土搅拌墙。
