Vacuum preloading construction method for coastal soft foundation treatment
The invention relates to a vacuum preloading construction method for coastal soft foundation treatment, and belongs to the technical field of soft foundation construction. According to the construction method, the slurry mixing piles serve as the sealing wall, the construction procedures of bottom layer medium-coarse sand backfilling, geotechnical cloth and RNG geogrid laying, drainage plate driving and inserting, second layer medium-coarse sand backfilling, vacuum pipeline embedding, medium-fine sand backfilling and geotechnical cloth and sealing film laying are conducted, vacuum preloading is conducted firstly after construction, and then the vacuum degree continues to be improved. The built sealing wall is good in sealing effect, high in strength and high in condensation speed, a good vacuumizing condition is provided for vacuum degree control of a vacuum preloading area, and the soft soil foundation can reach the designed bearing capacity more quickly through the construction method.
本发明涉及沿海软弱地基处理的真空堆载预压施工方法，属于软弱地基施工技术领域，本发明以泥浆搅拌桩作为密封墙、并通过回填底层中粗砂、铺设土工布、RNG土工格栅、打插排水板、回填第二层中粗砂、埋设真空管路、回填中细砂、铺设土工布和密封膜的施工工序，并在施工后先进行真空预压，然后在继续提高真空度的施工方法，所构筑的密封墙不仅密封效果好，且强度高，凝结速度快，并为真空堆载预压区的真空度控制提供了良好的抽真空条件，且本发明的施工方法能使软土地基更快地达到设计承载力。
