PRC prestressed pipe pile anchor cable deep foundation pit supporting system and construction method thereof
The invention relates to the technical field of foundation pit supporting construction, and particularly discloses a PRC prestressed pipe pile anchor cable deep foundation pit supporting system and a construction method thereof.The supporting system comprises PRC prestressed pipe piles which are arranged along the side of a foundation pit at intervals to form row piles, water stop stirring piles are arranged on the outer sides of the pipe piles, and every two adjacent stirring piles are arranged in a crossed mode; two pre-stressed anchor cables are arranged on the upper portion of the foundation pit and comprise the first anchor cable locked on the top beam and the second anchor cable locked on the waist beam, the top beam is connected to the top of the PRC pre-stressed pipe pile, the waist beam is arranged on the upper portion of the middle of the PRC pipe pile, and the first anchor cable and the second anchor cable are arranged on the upper portion of the middle of the PRC pipe pile. The supporting system solves the problem that an existing supporting structure cannot completely resist the pressure of soil around the foundation pit, meanwhile, underground water in the soil body on the outer side of the foundation pit can be prevented from seeping into the foundation pit, large supporting anchoring force is formed on the upper portion and the lower portion of the foundation pit through the supporting system, and the good supporting effect is achieved.
本发明涉及基坑支护施工技术领域，具体公开了一种PRC预应力管桩锚索深基坑支护体系及其施工方法，该支护体系采用包括沿基坑边侧间隔布置形成排桩的PRC预应力管桩，管桩外侧设置有止水搅拌桩，相邻两根搅拌桩之间相交设置，从而形成止水搅拌桩帷幕，在基坑上部设置有两道预应力锚索，包括锁定在冠梁上的第一道锚索和锁定在腰梁上的第二道锚索，冠梁连接在PRC预应力管桩顶部，腰梁布置在PRC管桩中部靠上的部位，该支护体系解决了现有支护结构无法完全抵抗基坑四周土压力的问题，同时能避免基坑外侧土体中的地下水向基坑内渗流，该支护体系使对基坑上部和下部形成较大支护锚固力，具有较好的支护效果。
