Vacuum preloading soft soil foundation reinforcing device of buoyant raft type cushion layer and method of vacuum preloading soft soil foundation reinforcing device
The invention relates to a vacuum preloading soft soil foundation reinforcing device of a buoyant raft type cushion layer and a method thereof.The reinforcing device comprises a sealing wall built on the periphery of a soft soil foundation in a surrounding mode, the soft soil foundation in the sealing wall is covered with the buoyant raft type cushion layer, and a drainage plate is arranged below the buoyant raft type cushion layer; the drainage plate is vertically inserted into the soft soil foundation, the upper end of the drainage plate penetrates into the buoyant raft type cushion layer, the buoyant raft type cushion layer is covered with a vacuum sealing film, the buoyant raft type cushion layer is externally connected with a vacuum loading system, and the vacuum loading system is used for generating vacuum negative pressure in the buoyant raft type cushion layer so that water of the soft soil foundation can be sucked and drained through the drainage plate. The reinforcing device can conduct construction operation on common soft soil foundations, ultra-soft soil foundations and suspended sludge foundations, a large number of sand cushion layers do not need to be stacked in the construction process, reinforcing can be completed without repeated treatment, a large number of sand resources are saved, the pre-pressing effect is good, the construction period is short, the efficiency is high, the floating raft type cushion layers can be repeatedly used, and the construction cost is reduced. And the environment is not damaged or polluted, so that the construction cost is reduced, and the environment is effectively protected.
本发明涉及一种浮筏式垫层的真空预压软土地基加固装置及其方法，加固装置包括围筑于软土地基四周的密封墙，密封墙内软土地基上覆盖有浮筏式垫层，浮筏式垫层下方设有排水板，排水板竖向插入于软土地基且上端穿进浮筏式垫层内，浮筏式垫层上覆盖有真空密封膜，浮筏式垫层外接有真空加载系统，真空加载系统用于在浮筏式垫层内产生真空负压，以通过排水板吸排软土地基的水。本加固装置能在一般的软土地基、超软弱土地基以及悬浮淤泥地基进行施工作业，施工过程无需堆压大量的砂垫层，无需多次处理即可完成加固，节约大量的砂资源，预压效果好，施工周期短效率高，且浮筏式垫层可重复使用，不会破坏或污染环境，既降低了施工成本，又有效保护了环境。
