Low-water-level precipitation vacuum and surcharge united preloading reinforcement deep soft foundation method and system
The invention discloses a low-water-level inverted siphon precipitation vacuum and surcharge united preloading reinforcement deep soft foundation system. The low-water-level inverted siphon precipitation vacuum and surcharge united preloading reinforcement deep soft foundation system comprises a soft soil foundation, a surcharge, plastic drainage boards, water absorption pipelines, precipitation wells, a filter cloth, a sand bed, a sealing film, a vacuum pump, a water drawing pit, a water drawing box and a centrifugal pump. According to the low-water-level inverted siphon precipitation, vacuumand surcharge united preloading reinforcement deep soft foundation system disclosed by the invention, a low-water-level inverted siphon precipitation vacuum and surcharge united preloading reinforcement deep soft foundation method is adopted, a low-water-level design idea of the vacuum water drawing box is provided, an idea of inverted siphon is combined to enable the zero point of the water level of the system to move downwards, so that the underground water level of the reinforcement site is effectively reduced; the inverted siphon effect is formed between the precipitation wells and the water drawing box, so that the underground water level of the site is reduced by the system, and vacuum pressure of lied soft soil can also be substantially increased; the ground stabilization to the deep soft soil is greatly improved by the processing method, duration can be shortened, and construction maintenance cost is reduced; and the method is simple in technology, and convenient to implement,and can be used for practical engineering.
本发明公开了一种低位倒虹吸降水真空联合堆载预压加固深厚软基系统，包括软土地基、堆载、塑料排水板、吸水管道、降水井、滤布、砂垫层、密封膜、真空泵、汲水坑、汲水箱、离心泵。采用低位倒虹吸降水真空联合堆载预压加固深厚软基的方法，提出了真空汲水箱的低水位设计思路，结合倒虹吸的理念，将系统水位零点下移，以有效降低加固场地地下水位。在降水井和汲水箱之间形成倒虹吸效应，不仅系统降低场地的地下水位，还能大幅度提升下卧软土的真空压力。该处理方法对深厚软土的地基加固有着较大的改进，可以缩短工期，降低施工维护成本。且该方法工艺简单，实施方便，可用于实际工程。
