Single-penetrating rigid pile composite foundation and construction method thereof
The invention provides a single-piercing rigid pile composite foundation and a construction method thereof, the pile bottom ends of rigid piles of the single-piercing rigid pile composite foundation are arranged on bedrock, a mattress layer is arranged at the top ends of the piles, and a bidirectional geogrid is arranged in the middle of the mattress layer. Aiming at the stratum conditions that the soil layer depth is small, the rock-soil boundary fluctuates greatly, and the compressibility of the lower soil layer relative to the upper soil layer is high, the problems that the bearing capacity of a covering layer foundation is insufficient, the excavation volume of a thick covering layer foundation is large, the dam body pouring amount is large, the slope is high, the occupied area is large, construction is difficult, and the construction period is long can be effectively solved. While the effect of the composite foundation is achieved, construction is easy and convenient, practicability is high, and large-area application and popularization can be achieved.
本发明提供一种单刺入刚性桩复合地基及其施工方法，单刺入刚性桩复合地基的刚性桩的桩底端置于基岩，桩顶端布设褥垫层，双向土工格栅布置于褥垫层的中部。本发明针对土层深度小、岩土分界线起伏较大且下部土层相对上部土层压缩性较高的地层条件，可以有效解决覆盖层基础承载力不足、厚覆盖层基础开挖量大、坝体浇筑量大、高边坡、占地较多、施工困难、施工工期长的问题。本发明在保证发挥复合地基的作用的同时，施工简便，实用性强，可大面积推广应用。
