Construction method for improving bearing capacity of complex stratum foundation
The invention discloses a construction method for improving the bearing capacity of a complex stratum foundation, which adopts a screw pile and lime soil compaction piles to jointly reinforce a foundation with staggered soft and hard soil layers, and specifically comprises the following steps of: arranging a plurality of lime soil compaction piles outside a screw pile by taking the screw pile as a center in a surrounding manner; a plurality of lime soil compaction piles are connected together through screw pile caps and screw piles to jointly form a composite foundation, a plurality of lime soil compaction piles, the screw pile in the center and the screw pile caps jointly form a foundation unit, a plurality of foundation units are distributed in a matrix mode, a double-layer cushion layer is constructed on the upper portions of the foundation units to form a foundation, and the double-layer cushion layer is arranged on the lower portion of the foundation unit. Therefore, the upper load is borne. The technical problem that pile forming is difficult in the complex stratum of soft and hard staggered distribution of the ground surface soil layer is solved, the pile forming efficiency can be improved, namely, the construction efficiency is improved, and the requirements of safety, economy, environmental protection, applicability and the like are met.
本发明公开了一种提高复杂地层地基承载力的施工方法，采用螺杆桩结合灰土挤密桩共同对软硬土层交错分布的地基进行加固处理，具体为：多根灰土挤密桩以一根螺杆桩为中心围设于螺杆桩外，多根灰土挤密桩通过螺杆桩桩帽与螺杆桩连接在一起共同组合成复合地基，多根灰土挤密桩、中心的螺杆桩以及螺杆桩桩帽共同组成为一个地基单元，多个地基单元呈矩阵分布，多个地基单元上方施作双层垫层形成为地基，以承受上部荷载。本发明解决了地表土层软硬交错分布这一复杂地层中成桩困难的技术难题，且能够提高成桩效率即提高施工工效，满足安全、经济、环保、适用性等要求。
