1. a kind of use can position the vacuum prepressing ground foundation treatment method of water-permeable pipe, it is characterised in that comprise the steps of:

  • 1) smooth location, carries out temporary drain.2) sand bedding course paves, it is ensured that its flatness, paving thickness, packing reaches design requirement.3) position is set with what theodolite etc. made water-permeable pipe in fixed reinforcing scope, plugging can position water-permeable pipe to settingMeter height.4) lay vacuum tube and carry out its overlap joint work with water-permeable pipe, lay one layer of geotextiles, be slightly larger than its laying scopeStabilization zone scope, excavates sealing ditch.5) lay second half sand bedding course and lay diaphragm seal, by film surrounding along sealing ditch inwall embedment sealing ditch, use clay backfillingIt is closely knit and pour water.6) vacuum main is connected sealing with vavuum pump by going out membrane device.7) start vavuum pump to vacuumize, the water and air in the soil body under diaphragm seal is extracted out, persistently vacuumize until unloading.8) recovery can position water-permeable pipe and treat that next time uses after engineering terminates.
