High vacuum compaction soft foundation treatment method
The invention discloses a high vacuum compaction soft foundation treatment method. The method comprises the steps that step one, a vacuum tube is inserted into a soil body in a construction area, theupper end of the vacuum tube is connected to vacuumizing equipment through a hose, and the vacuumizing equipment is started to vacuumize to generate negative pressure on the soil body; and step two, tamping equipment is used for tamping the soil body with suitable energy in the construction area to generate positive pressure on pore water of the soil body, so that water drainage of the soil body is accelerated, wherein the vacuum tube is provided with drainage holes in the entire thickness range of soft soil to be treated, and filter cloth covers the length range of the drainage holes. Due tothe fact that the drainage holes are formed in the entire depth area of the treated soil body, of the used vacuum tube, the effective distance of pressure difference drainage is the shortest, under the simultaneous action of vacuumizing and tamping, the drainage effect is better, the common quality problem that ''spring soil'' is liable to form in an original construction method is overcome, construction costs and the construction period are significantly reduced, and the construction quality is reliable.
本发明公开了一种高真空击密软地基处理方法，包括：步骤一、在施工区域的土体中插入真空管，真空管的上端用软管连接至抽真空设备，启动抽真空设备抽真空，对土体产生负压；步骤二、使用夯击设备在施工区域内对土体进行适能量夯击，以对土体的孔隙水产生正压，从而加速土体中水的排出；其中，所述真空管在需处理软土的整个厚度范围内都开设有排水孔，并在开设排水孔的长度范围内包覆滤布。由于所使用的真空管是在被处理土体的全部深度区域内开设排水孔，使得压力差排水的有效距离最短，在抽真空及夯击的同步作用下，排水效果更好，克服了原工法易形成“弹簧土”的质量通病，施工成本和施工周期都显著降低，并且施工质量可靠。
