Technology for treating deep soft soil foundation through vacuum preloading of low-permeability solidified soil composite film
The invention relates to the technical field of soft soil foundation treatment, and particularly discloses a technology for treating a deep soft soil foundation through vacuum preloading of a low-permeability solidified soil composite film. Then sequentially carrying out the operations of plastic film vacuum prepressing, first-layer solidified soil loading, second-layer plastic vacuum film laying, second-layer solidified soil loading and site sealing; high-vacuum preloading in the whole soft foundation treatment process is achieved, the solidified soil and plastic film composite film sealing technology is adopted, after stacking loading is conducted on the film, the vacuum under the film is stabilized to be 85 kpa or above, and the problem that the vacuum degree is sharply attenuated after stacking loading is conducted through a traditional vacuum degree technology is solved; by the adoption of the vacuum preloading technology, the total load can reach 120 kpa or above, and compared with a traditional vacuum preloading technology with the same stacking height, the total preloading load of the vacuum preloading technology is larger by 20% or above.
本发明涉及软弱土地基处理技术领域，具体公开了低渗透性固化土复合膜真空预压处理深厚软土地基技术，在实施时，首先布设真空系统，然后依次进行塑料膜真空预压、首层固化土加载、铺设第二层塑料真空膜、第二层固化土加载以及场地密封的操作；本发明实现了软基处理全程高真空预压，采用固化土、塑料膜复合膜密封技术，在膜上堆载后，膜下真空稳定在85kpa以上，克服了传统真空度技术在堆载后真空度急剧衰减的难题；实现了大超载预压，采用本技术总荷载可达到120kpa以上，同堆载高度相当的传统真空预压技术相比，其总预压荷载要大20％以上。
