Wind power tower pile foundation used in self weight collapsing loess site and construction method
The invention belongs to the technical field of foundations, and particularly relates to a wind power tower pile foundation used in a self weight collapsing loess site and a construction method. The wind power tower pile foundation is composed of foundation piles, a motor set tower foundation platform, a first layer of backfill, a dark apron, a second layer of backfill and an earth surface overbarden layer, wherein the foundation piles are arranged below a foundation pit with a stair-stepping side slope, the motor set tower foundation platform is arranged on the upper surface of a foundation pit bottom, and the first layer of backfill, the dark apron, the second layer of backfill and the earth surface overbarden layer are sequentially arranged around the motor set tower foundation platformfrom bottom to top. According to the wind power tower pile foundation used in the self weight collapsing loess site and the construction method, multichannel waterproof protection is carried out on the foundation within a large range, the possibility of foundation flooding is reduced, resource consumption is reduced, and the investment in the wind power tower foundation is reduced. By means of multichannel waterproofing, the collapse factor is eliminated, and safety and economy are realized. The wind power tower pile foundation restores the earth surface and protects the environment. Local materials are used, the materials are made full use of, and resources are saved.
本发明属于地基基础技术领域，尤其涉及一种自重湿陷性黄土场地风电塔架桩基础及施工方法。本发明通过设置在边坡为阶梯状的基坑下的基桩、设置在基坑底上表面的电机组塔架基础承台、从下至上依次设置在风电机组塔架基础承台四周的第一层回填土、暗散水、第二层回填土和地表覆土层构成。本发明在较大范围内对基础进行多道防水保护，降低了地基浸水可能，减少资源耗费，降低风电塔架地基基础投资。本发明通过多道防水，消除湿陷因素，安全经济。本发明恢复了地表，保护了环境。本发明就地取材，充分利用材料，节约资源。
