Section steel-concrete combined underground continuous wall structure and construction method thereof
The invention discloses a section steel-concrete combined underground continuous wall structure and a construction method thereof. The section steel-concrete combined underground continuous wall structure consists of a reinforced concrete underground continuous wall with reserved holes, section steel and grouting solidification retainers. A construction method of a basement based on a combined underground continuous wall comprises the following steps of placing a precast concrete underground continuous wall on site; inserting the section steel into the reserved holes; carrying out grouting ingaps for filling; carrying out basement construction; and after the completion of the basement construction, pulling out the section steel for recovery, and grouting for filling. According to the section steel-concrete combined underground continuous wall structure, the underground continuous wall is prefabricated, the section steel is inserted into the reserved holes after the underground continuous wall is placed at a proper position, the section steel is recovered after the completion of the basement construction, a concrete part is continually used as a permanent structure together with abasement outer wall or used as the basement outer wall after grouting treatment, and no rigid barriers exist under the basement after recovery of the section steel, so that resources are saved, and conditions are reserved for subsequent development of deep underground space.
本发明公开了型钢与混凝土组合式地下连续墙结构及其施工方法，该型钢与混凝土组合式地下连续墙由带预留孔洞的钢筋混凝土地下连续墙、型钢、注浆凝固护圈三部分组成。基于该组合式地下连续墙的地下室施工步骤如下：现场下放预制混凝土地下连续墙、在预留孔洞内插入型钢，间隙注浆填充，地下室施工，地下室施工完成后拔除回收型钢并注浆填充。本发明的地下连续墙采用预制式，地连墙安放到位后在其预留空洞内插入型钢，在地下室结构施工完成后，将型钢进行回收，混凝土部分灌浆处理后继续与地下室外墙一起或兼做地下室外墙作为永久结构使用，地下室以下在型钢回收后就没有任何刚性的障碍物，既节约了资源，又为后续深部地下空间开发预留了条件。
