Foundation treatment method for cast-in-place box culvert on soft soil foundation
The foundation treatment method for the cast-in-place box culvert on the soft soil foundation comprises the following steps that prefabricated reinforced concrete square piles are sunk, and the prefabricated reinforced concrete square piles penetrate through a soft soil layer to reach a hard rock layer; and the foundation pit is excavated below the design position of the connecting beam, and a sand cushion layer is laid. Concrete of the prefabricated reinforced concrete square pile above the designed pile top is chiseled away, and the anchoring steel bars are reserved. And a first plain concrete cushion layer is poured, connecting beam steel bars are bound, and concrete is poured. And a graded broken stone base layer is laid between the connecting beams, and vibration rolling is conducted on the graded broken stone base layer. And a layer of woven geotextile is laid on the graded broken stone base layer. A graded broken stone surface layer is laid on the woven geotechnical cloth, and the graded broken stone surface layer is subjected to vibration rolling. And a second plain concrete cushion layer is poured on the graded broken stone surface layer, and foundation treatment of the cast-in-place box culvert on the soft soil foundation is completed. According to the foundation treatment method, the problem of soft soil roadbed stability during box culvert construction is solved, and the bearing capacity and stability of the foundation are improved.
本申请公开了一种软土地基上现浇箱涵的地基处理方法，包括以下步骤：沉入预制钢筋混凝土方桩，预制钢筋混凝土方桩穿过软弱土层达到坚硬岩层。开挖基坑至连系梁设计位置下方，铺设砂垫层。将设计桩顶以上的预制钢筋混凝土方桩的混凝土进行凿除，锚固钢筋进行保留。浇筑第一素混凝土垫层，绑扎连系梁钢筋并浇筑混凝土。在连系梁之间铺设级配碎石基层，对级配碎石基层进行振动碾压。在级配碎石基层上铺设一层有纺土工布。在有纺土工布上铺设级配碎石面层，对级配碎石面层进行振动碾压。在级配碎石面层上浇筑第二素混凝土垫层，完成软土地基上现浇箱涵的地基处理。本申请的地基处理方法解决了箱涵施工时软土路基稳定问题，提高了地基的承载力和稳定性。
