Abstract

The invention discloses a system and a method for drainage consolidation for a soft soil foundation. The system comprises plastic drainage plates, siphons, plate shoes, a heaped load, a water collection well and a water suction pump, wherein side ditches are excavated in the soft soil foundation and to be below an underground water level; the plastic drainage plates are inserted in the side ditches and arranged in a quincunx shape; one plate shoe made from the same material as each plastic drainage plate is installed at one end inserted in the soft soil foundation, of the plastic drainage plate; a water inlet port of one siphon is inserted in each plastic drainage plate, and a water outlet port of the siphon stretches into the water collection well located in the vicinity of the soft soil foundation; the side ditches are filled with soil; and the heaped load is placed on the surface of the soft soil foundation. The water suction pump is started to suck water, so that a water level in the water collection well is lowered, and the drainage consolidation for the soft soil foundation is promoted.

Description

technical field [0001] The invention belongs to the field of geotechnical engineering, in particular to a system and method for treating soft ground. Background technique [0002] The southeast coastal area of ​​our country has always been a place of prosperity, and a large number of people have gathered in this area. With the continuous influx of people, the problem of originally scarce land resources has become more and more tense. In order to adapt to the continuous development of economic construction in the southeast coastal zone, buildings had to be built on soft soil foundations. Due to the low shear strength, high water content, poor water permeability and certain rheological properties of the soft soil foundation, it is necessary to deal with it accordingly when building infrastructure on its upper part. Among all the soft soil foundation treatment methods, the drainage consolidation method is more commonly used, while the traditional drainage consolidation method ...
