Strip wall type underground diaphragm wall composite anchorage foundation and construction method thereof
According to the strip wall type underground diaphragm wall composite anchorage foundation and the construction method thereof, loads are transmitted to surrounding soil through a shaft type underground diaphragm wall, a lining, a main body and the strip wall type underground diaphragm wall, the bottom of the strip wall type underground diaphragm wall enters a bearing stratum, and the beneficial bearing contribution of the strip wall type underground diaphragm wall is fully exerted; the advantage that the large side area of the strip wall type diaphragm wall provides side resistance can be utilized, the safety coefficient of horizontal cable force can be very high, it is not needed to excavate deeply to construct a large body to increase the self weight to improve the horizontal bearing capacity, and the size and the self weight of the whole anchorage are reduced; the arch effect self-stabilization effect of the shaft type underground diaphragm wall is fully utilized, under the arch effect self-stabilization effect of the shaft type underground diaphragm wall, the burial depth of the shaft type underground diaphragm wall only needs to meet the safety and stability requirements of main body foundation pit construction, the burial depth of the shaft type underground diaphragm wall does not need to be embedded into a rock stratum and does not need to be large, the excavation depth is greatly reduced, and the construction risk is reduced. The engineering cost is saved, and the problems of foundation pit supporting safety and anchorage foundation construction are effectively solved.
本发明涉及一种条壁式地下连续墙复合锚碇基础及其施工方法，通过井筒式地连墙、内衬、主体和条壁式地连墙传递荷载至周围土体，条壁式地连墙底部进入持力层，充分发挥了条壁式地连墙的有利承载贡献，能够利用条壁式地连墙较大侧面积提供侧阻力优势，水平缆力的安全系数就会很高，不需要开挖较深以施工较大的主体增加自重来提高水平承载力，减小整个锚碇体积和自重；还充分利用了井筒式地连墙的拱效应自稳作用，在井筒式地连墙的拱效应自稳作用下，井筒式地连墙的埋深仅需满足主体基坑施工安全稳定要求，井筒式地连墙的埋深不需嵌入岩层及较大埋深，这极大减少开挖深度和降低施工风险，节省工程造价，有效解决了基坑支护安全和锚碇基础施工难题。
