Tooth-shaped curtain herringbone precast pile enclosure structure and construction method
The invention relates to a tooth-shaped curtain herringbone precast pile enclosure structure and a construction method.The tooth-shaped curtain herringbone precast pile enclosure structure comprises a strip-shaped curtain wall, a plurality of tooth-shaped curtain walls, a plurality of front-row precast piles, a plurality of rear-row precast piles and a coping plate, and the tops of the rear-row precast piles are located in the middles of the upper ends of the tooth-shaped curtain walls; the bottoms of the rear-row precast piles are located on the rear portion of the lower end of the tooth-shaped curtain wall, and the strip-shaped curtain wall is a continuous vertical enclosure wall. The tooth-shaped curtain wall supporting structure has the beneficial effects that the tooth-shaped curtain wall has the restraining effect on a soil body in a slip crack face, soil between the tooth-shaped curtain walls and the whole wall body form the effect similar to a gravity type enclosure structure, the supporting system has the obvious load reducing effect, the soil pressure on the supporting structure can be greatly reduced, and therefore the supporting depth can be obviously increased, and the supporting effect is improved. No inner support is beneficial to excavation in a pit and underground structure construction, and no pre-stressed anchor rod can avoid red line limitation of a construction site and underground obstacles outside the pit.
本发明涉及一种齿形帷幕人字形预制桩围护结构及施工方法，其中，齿形帷幕人字形预制桩围护结构包括条形帷幕墙、多个齿形帷幕墙、多个前排预制桩、后排预制桩以及压顶板，后排预制桩的顶部位于齿形帷幕墙上端的中部，后排预制桩的底部位于齿形帷幕墙下端的后部，条形帷幕墙为一道连续的竖向围护墙。本发明的有益效果：齿形帷幕墙对滑裂面内土体的约束作用，齿形帷幕墙之间的土与整个墙体形成类似重力式围护结构的效果，使得支护体系具有明显的减载效应，可大幅度降低支护结构上的土压力，因此，可明显增加支护深度，无内支撑有利于坑内开挖及地下结构施工，无预应力锚杆则可以避免施工场地红线限制，在坑外产生地下障碍物。
