Reinforcement treatment method for soft soil foundation
The invention discloses a reinforcement treatment method for a soft soil foundation. The reinforcement treatment method for the soft soil foundation comprises the following steps that a plurality of vertical dewatering wells are constructed in the soft soil foundation; a plurality of floral pipes are arranged between the two dewatering wells, and transverse drainage and gas injection channels are formed in the soft soil foundation through the floral pipes; gas is injected into the dewatering wells and enters the floral pipes through the dewatering wells, and surrounding soil is punched through holes of the floral pipes to form water seepage channels flowing to the floral pipes; underground water is collected to the dewatering wells through the floral pipes under the action of the dead weight of the soil on the upper parts of the floral pipes, accumulated water in the dewatering wells is pumped out, and consolidation settlement of the soft soil foundation is completed. According to the reinforcement treatment method for the soft soil foundation, the problems that the earthwork volume needed by conventional preloading is large, and the secondary transfer cost is high are solved, the water seepage channels in the depth direction are formed through the floral pipes, the distribution of the water seepage channels in the soft soil foundation is wider, and the treatment period is greatly shortened.
本发明公开了一种软土地基的加固处理方法，包括以下步骤：在软土地基中施工多个竖向的降水井；在两个所述降水井之间布置若干花管，通过所述花管在软土地基内部形成横向排水、注气通道；向所述降水井内部注入气体，气体经过所述降水井进入各所述花管，通过所述花管的开孔冲切周围土体，形成流向花管的渗水通道；在花管上部土体自重的作用下，地下水经所述花管汇集至所述降水井，抽出各所述降水井内的积水，软土地基完成固结沉降。本发明避免了常规堆载预压所需土方量大、二次转运费用高的问题，而且通过花管形成沿深度方向的渗水通道，渗水通道在软土地基内部的分布更广，大大缩短处理工期。
