Abstract
The present invention is a soft soil treatment method. Given soil profiles of site subsections investigated by using handy augers, coefficient of permeability and water contents of each soil stratum, rely on soil information-based control, install vacuum pipes, impart vacuum effort, uninstall partial vacuum pipes and impart vacuum-compaction efforts. Densify the site by dynamic or vibration compactions, with varied energies each cycle, to further save time and cost, eliminate the differential settlements and rubber soils, and guarantee construction quality.
Claims6
An information-based high vacuum densification method for fast treatment of soft soil, characterizing in that the method comprising the following steps:
- Step 1, divide the site into several subsections, use handy augers to investigate the soil profiles of subsections, estimate the expected settlements of subsections;
- Step 2, install water-tight systems around the site and block the seepage of ambient groundwater;
- Step 3, install vacuum pipes in subsections, vacuum pipes are installed with layered matrix form, and connected to the ground horizontal pipes and vacuum systems, pizometers are placed in each soil stratum, dynamic trials are conducted to probe the ramming energies, measure the pore water pressure dissipation of each stratum and determine the vacuum pipe spacing;
- Step 4, impart several cycles of high vacuum and inter-moderated compactions (vacuum-compaction) in subsections.
