Soft soil foundation riprap silt squeezing structure and construction method
The invention relates to the field of soft soil foundation construction, in particular to a soft soil foundation riprap silt squeezing structure and a construction method.The soft soil foundation riprap silt squeezing structure is arranged at a foundation pit excavated on the soft soil foundation surface, the riprap silt squeezing structure comprises a backfill stone layer located in the foundation pit, the backfill stone layer sinks to the bottom of the foundation pit, and a plurality of independent stone piles are arranged in the backfill stone layer; a waterproof shape fixing cover for preventing water and stabilizing the shape of the stone pile is arranged on the outer side of the stone pile; a gravel inverted filter layer is further arranged on the top of the backfill stone layer, and the upper surface of the gravel inverted filter layer is flush with the ground surface of the soft soil foundation. According to the soft soil foundation pit, the stone heap and the waterproof consolidation layer are utilized, erosion of underground water to the filling in the soft soil foundation pit is weakened, and the effect of improving the stability of the bearing capacity of the soft soil foundation filling is achieved.
本申请涉及软土基施工的领域，尤其是涉及一种软土基抛石挤淤结构及施工方法，其设置于软土基地表挖设的基坑处，所述抛石挤淤结构包括位于基坑内的回填石料层，回填石料层沉于基坑底部，回填石料层内有多个单独的石料堆，石料堆外侧设置有用于防水及稳固石料堆形状的防水固形罩；所述回填石料层顶部还设置有碎石反滤层，碎石反滤层上表面与软土基的地表面齐平。本申请中，利用石料堆和防水固结层，减弱了地下水对软土基基坑内填筑物的冲蚀，达到提高了软土基填筑物承载力的稳定性的效果。
