Engineering construction method of underground protective structure
The invention discloses an engineering construction method of an underground protective structure. The engineering construction method of the underground protective structure comprises the following steps of: S1, constructing continuous walls on a construction site, wherein the continuous walls comprise a first continuous wall and a second continuous wall which are arranged at intervals; S2, manufacturing at least two steel open caissons arranged at intervals at designated positions between the two surfaces of the continuous walls, excavating soil in the steel open caissons and between the steel open caissons to enable the steel open caissons to sink to a designed depth, making a hollow part between the steel open caissons form a first space, and making a hollow part in the steel open caissons form a second space; S3, constructing a first main body structure in the first space between the steel open caissons; S4, dismantling the steel open caissons and constructing a second main body structure in the second space; and S5, repeating the steps until all main body structures are constructed. The underground protective structure built by the method is good in integrity. Extra construction investment such as purlins, lattice columns and the like is not needed, the formed construction space is large, and the method is particularly suitable for slender foundation pit supports such assubways, underpass tunnels, and pipe galleries.
本发明公开了一种地下防护结构的工程施工方法，包括如下步骤：S1、在施工现场进行连续墙的施工，连续墙包括间隔设置的第一连续墙和第二连续墙；S2、在两面连续墙之间的指定位置制作形成至少两个间隔设置的钢沉井，进行钢沉井内及钢沉井间挖土，使钢沉井下沉至设计深度，钢沉井间的挖空部分形成第一空间，钢沉井内的挖空部分形成第二空间；S3、在钢沉井间的第一空间内进行第一主体结构施工；S4、将钢沉井拆除并在第二空间内进行第二主体结构施工；S5、重复上述步骤直至全部主体结构施工完毕。本发明方法建造的地下防护结构整体性好。无需围檩、格构柱等额外的施工投入，形成的施工空间大，尤其适用于细长型基坑支撑，如地铁、下穿隧道、管廊等。
