Construction method applied to drainage consolidation of soft soil foundation by using natural gravitational potential energy
The invention belongs to the technical field of geotechnical engineering soft soil foundation treatment, and particularly relates to a construction method applied to drainage consolidation of soft soil area construction industrial and civil buildings, environmental engineering and the like. According to the method, holes are vertically formed in the soft soil, the natural gravitational potential energy is fully utilized to generate pressure difference in the radial direction of underground deep soil pore water inside and outside a longitudinal water filter pipe with slender holes, the pore water and the like in the soft soil are released and are enriched and discharged out of the ground in the water filter pipe, and the phase change of the transverse underground soil is completed; and forenvironmental engineering projects, under the action of natural gravitational potential energy, solid-liquid separation of polluted soil is completed. According to the method, the pile holes are vertically generated and are tamped into single discrete piles through discrete materials, then the discrete piles forming a group form a pile group effect, soil bodies between the piles are compacted again, pile and soil jointly stressed discrete pile groups are formed, upper structure loads are borne jointly, the composite foundation with the good consolidation effect is formed, and the method is suitable for large-area and deep soft soil foundation treatment engineering and environment solid-liquid separation engineering.
本发明所属岩土工程软土地基处理技术领域，特别涉及应用于软土地区修筑工业与民用建筑和环境工程等实施排水固结的工法，具体涉及先在软土内竖向造孔，充分利用自然重力势能在纵向带细长孔的滤水管内外造成地下深层土体孔隙水径向产生压力差，把软土内孔隙水等释放出来，在滤水管内富集，排出地面，横向地下土体相变完成；对于环境工程类项目，在自然重力势能作用下，污染土体固液分离实施完结；竖向产生桩孔用散体材料夯击制成单体散体桩，再组成群体的散体桩形成群桩效应，桩间土体再次被挤密，形成桩土共同受力散体群桩，共同承担上部结构荷载，形成固结效果较好的复合地基的施工工法，适用于大面积和深厚软土地基处理工程和环境固液分离工程。
