Large-area soft foundation reinforcement pile body quick-drainage method
The invention provides a large-area soft foundation reinforcement pile body quick-drainage method, and belongs to the technical field of foundation treatment. According to the large-area soft foundation reinforcement pile body quick-drainage method, a light well point pipe is mainly used for reducing the water content of soil around a pile body, and when quick drainage is achieved at the buried depth of the light well point pipe, the hyperstatic pore water pressure generated by vibration of the soil is quickly released; and the quick-drainage pile body is vacuumized, certain negative pressureis generated on the soil around the pile body, under the action of the negative pressure, the mucky soil around the pile body shrinks towards the pile body, thus the consolidation degree of the soil is enhanced, and under the action of the multiple effects, the physical and mechanical indexes such as the porosity, the water content and the compression modulus of the soil can be changed.
本发明提供了一种大面积软弱地基加固桩体速排方法，属于地基处理技术领域。本发明中，轻型井点管的主要作用是降低桩体周边土体含水量，在轻型井点管入土深度实现快速排水的同时，快速释放土体因振动而产生的超静孔隙水压力；通过速排桩体抽真空，对桩体周边土体产生一定的负压，使桩体周边淤泥质土在负压作用下，向桩体收缩，从而增强了土体的固结度，在上述多重效果作用下，土体的物理力学指标如孔隙比、含水率、压缩模量都可以得到改变。
