Collapsible loess site wind power tower extended foundation and construction method
The invention belongs to the technical field of foundations, and particularly relates to a collapsible loess site wind power tower extended foundation and a construction method. The collapsible loesssite wind power tower extended foundation is composed of a composite foundation cushion layer, a wind power unit tower foundation, first backfill, hidden bulk water, second backfill and an earth surface overburden layer, wherein the composite foundation cushion layer is arranged on the upper surface of a foundation pit bottom of a foundation pit, the wind power unit tower foundation is connected to the composite foundation cushion layer, and the first backfill, the hidden bulk water, the second backfill and the earth surface overburden layer are sequentially arranged around the wind power unittower foundation from bottom to top. The foundation is subjected to multiple layers of waterproof protection within a large range, the water soaking possibility of the foundation is reduced, the resource consumption is reduced, and the investment of the wind power tower foundation is reduced. By means of the multiple layers of waterproof protection, the collapse factor is eliminated, and the collapsible loess site wind power tower extended foundation is safe and economical. The earth surface is restored, and the environment is protected. Local materials are used, the materials are fully utilized, and resources are saved. An original loess structure is damaged by compaction piles triangularly arranged at the foundation pit bottom, the collapse of the foundation is eliminated or partially eliminated, and the bearing force of the foundation is improved.
本发明属于地基基础技术领域，尤其涉及一种湿陷性黄土场地风电塔架扩展基础及施工方法。本发明通过设置在基坑的基坑底上表面的复合地基垫层、连接在复合地基垫层上的风电机组塔架基础、从下至上依次设置在风电机组塔架基础四周的第一次回填土、暗散水、第二次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。本发明通过呈三角形布置于基坑底的挤密桩破坏黄土原有结构，消除或部分消除地基的湿陷性，提高了地基承载力。
