Soft soil consolidation processing method by utilizing hard hollow tubes with pores reserved on side walls

2013 
The invention relates to a processing method for drainage consolidation of soft soil foundations. The processing method includes that geotextile with water permeability is wrapped outside hard hollow tubes with pores reserved on side walls, the hard hollow tubes are beaten into saturated soft soil, the tops of the hard hollow tubes are connected with a negative pressure system formed by sealing flexible tubes and a vacuum pump, negative pressure is formed in the hard hollow tubes through start-up of the vacuum pump, pore water in the soft soil flows into the hard hollow tubes through the pores on the side walls of the hard hollow tubes and then is extracted to be drained to a ground collecting system, the geotextile wrapped outside the tubes has a function of preventing soil particles from entering the tubes, and the pore water in the soft soil is drained by the system to speed up consolidation of the soft soil. By the processing method, the problem of negative pressure loss of plastic drainage plates is solved, sealing films and sand mats are not needed to be arranged on the top of the soft soil foundations, drainage effect is good, and construction period is shortened; and the hard hollow tubes can be reused, so that cost and pollution are reduced.
