Construction method and structure for deep foundation pit inner support plate type quick support replacement
The invention discloses a construction method and structure for deep foundation pit inner support plate type quick support replacement. According to the construction method, when a basement structureis constructed, supporting concrete plates are additionally arranged between a basement outer wall and vertical enclosing structure steel supporting piles, and inner supports are replaced by the supporting concrete plates to prevent a deep foundation pit from collapsing. Therefore, the support replacement and removal work can be completed when the basement structure is constructed; due to the factthat the support replacement structure is lower one layer than the inner supports, the construction of the upper basement structure can be carried out after the dismantling of the inner supports is completed, the risk of leakage caused by secondary pouring of reserved holes in the basement outer wall can be avoided, the construction quality of the whole basement structure is effectively improved,the construction progress is accelerated, manpower and material resources are saved, the construction difficulty is small, and the safety is high.
本发明公开了一种深基坑内支撑板式快速换撑的施工方法及结构，本发明是在地下室结构施工时，在地下室外墙与竖向围护结构型钢支护桩之间增设换撑砼板的施工方法，由换撑砼板替代内支撑防止深基坑出现塌陷。因此可以在地下室结构施工的同时完成换撑拆除工作，因换撑结构比内支撑低一层，可完成内支撑拆除以后再进行上部地下室结构的施工，可避免地下室外壁内支撑预留的孔洞二次浇注产生渗漏的风险，有效提高了整个地下室结构的施工质量，加快了施工进度，节省了人力、物力投入，施工难度小且安全性高。
