Tooth-shaped curtain double-row precast pile enclosure structure and construction method
The invention relates to a tooth-shaped curtain double-row precast pile enclosure structure and a construction method.The tooth-shaped curtain double-row 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 fixed to the tops of the strip-shaped curtain wall and the tooth-shaped curtain walls, and the strip-shaped curtain wall is a continuous vertical enclosure wall; the invention further relates to a construction method. The tooth-shaped curtain wall supporting structure has the beneficial effects that the tooth-shaped curtain wall has the restraining effect on the soil body in the slip crack surface, and the soil between the tooth-shaped curtain walls and the whole wall body form the effect similar to a gravity type enclosure structure, so that the supporting system has an obvious load reducing effect, the soil pressure on the supporting structure can be greatly reduced, the supporting depth can be obviously increased, and the supporting effect is improved. Or the supporting requirement can be met without arranging a supporting component, excavation in the pit and underground structure construction are facilitated without the inner support, and the situation that underground obstacles are generated outside the pit due to the red line limitation of a construction site can be avoided without the pre-stressed anchor rod.
本发明涉及一种齿形帷幕双排预制桩围护结构及施工方法，其中，包括条形帷幕墙、多个齿形帷幕墙、多个前排预制桩、后排预制桩以及固定在条形帷幕墙和齿形帷幕墙顶部的压顶板，所述条形帷幕墙为一道连续的竖向围护墙；还涉及施工方法。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，以及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，或无需设置支撑构件即可满足支护要求，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。
