Foundation pit supporting structure close to subway and subarea construction method
The invention discloses a foundation pit supporting structure close to a subway and a subarea construction method. The foundation pit supporting structure comprises a foundation pit area. The foundation pit area comprises an area A, an area B and an area C. The area A is a deep pit area away from the subway. The area B is a deep pit area close to a subway station. The area C is a deep pit area close to a subway tunnel. The area A, the area B and the area C each internally comprise a foundation pit external vertical enclosure system and a foundation pit internal horizontal supporting system. Different inter foundation pit separation wall systems are arranged between the area A and the area B and between the area B and the area C. The method mainly comprises the construction steps that the foundation pit area is divided, the foundation pit external vertical enclosure system is constructed, the foundation pit internal horizontal supporting system is constructed, a foundation pit is excavated, and different subarea inter foundation pit separation wall systems are constructed. Subarea construction is carried out in the area A, the area B and the area C sequentially through the five steps. The foundation pit supporting structure has the effect of reducing the possibility that when foundation pit construction is carried out close to the subway, foundation close to the subway is influenced.
本发明公开了一种临近地铁的基坑支护结构及分区施工方法，该基坑支护结构包括基坑区域基坑区域包括A区域、B区域和C区域，A区域为远离地铁深坑区域、B区域为靠近地铁车站深坑区域、C区域为靠近地铁隧道深坑区域，A区域、B区域和C区域内均包括基坑外部竖向围护体系、基坑内部水平支撑体系，且A区域和B区域、B区域和C区域之间均设有不同基坑间分隔墙体系，施工步骤主要包括划分基坑区域、基坑外部竖向围护体系施工、基坑内部水平支撑体系施工、开挖基坑、不同分区基坑间分隔墙体系施工，通过这五个步骤依次对A区域、B区域和C区域进行分区加工。本发明具有减少对临近地铁进行基坑施工时对地铁附近的地基造成影响的可能的效果。
