Quick consolidation sand-free direct discharge type vacuum preloading method
The invention discloses a rapid consolidation sand-free direct discharge type vacuum preloading method. The method comprises the steps that surface cleaning treatment is conducted on the original ground within the range of a foundation to be treated; laying a layer of soil engineering layer woven cloth on the surface subjected to surface cleaning treatment; a plurality of anti-clogging drainage plates are arranged in the foundation to be treated; a deep well type downcast pipe is arranged between the anti-clogging drainage plates, and the upper end of the deep well type downcast pipe is communicated with the vacuum filter pipe through a pipeline; the upper end of the anti-clogging drainage plate is seamlessly and directly connected with the vacuum branch pipe through a hand-shaped joint; a vacuum pipe network composed of the vacuum branch pipes is connected with the vacuum main pipe; a sealing film is laid in the range of the foundation to be treated; the water-gas separation equipment is connected with a vacuum main pipe for vacuumizing and draining water; unloading is conducted; vacuum transmission is deeper, consolidation response radius and vacuum degree distribution are more uniform, and energy conservation and environmental protection are achieved; besides the anti-clogging plastic drainage plate for dewatering, the deep well type dewatering pipe is arranged for dewatering, so that the dewatering depth is deeper, the construction period is greatly shortened, and the problem that the bearing capacity of a traditional process is insufficient is solved.
一种快速固结无沙直排式真空预压法，包括：对待处理地基范围内原地面进行清表处理；在清表处理后的表面，铺设一层土工层编织布；在待处理地基内，打设多个防淤堵排水板；在防淤堵排水板之间设置深层井式降水管,深层井式降水管上端通过管道与真空滤管连通；防淤堵排水板上端与真空支管通过手型接头无缝直连；将真空支管组成的真空管网连接真空主管；在待处理地基范围内铺设密封膜；通过水气分离设备连接真空主管抽真空排水；卸载；具备真空传递更深，固结响应半径，真空度分布更均匀，节能、环保；除防淤堵塑料排水板降水外，还通过设置深层井式降水管处理降水，降水深度更深，工期大大缩短，解决传统工艺承载力不够的问题。
