刚性桩复合地基联合围封墙在泵站中的应用

Application of Rigid Pile Composite Foundation Combined with Cement Mixing Pile Sealing Wall in Pumping Station Project

摘要:

本文根据济宁市引黄泵站工程的特点及实际情况,提出了预制管桩(PHC)和水泥搅拌桩相结合的地基处理方案,预制管桩(PHC)主要是提高地基承载力和减少地基沉降,解决承载力不足和沉降过大问题;水泥搅拌桩围封墙,用来提高地基的抗振动液化能力,该技术可为同类水利工程设计提供方案参考和思路借鉴。

Abstract:

According to the characteristics and actual situation of Yellow River pumping station project in Jining, a foundation treatment scheme combining precast pipe pile (PHC) and cement mixing pile is proposed in this paper. The precast pipe pile (PHC) is mainly to improve the bearing capacity of the foundation and reduce the settlement of the foundation, so as to solve the problem of insufficient bearing capacity and excessive settlement. Cement mixing pile enclosing wall is used to improve the anti-vibration liquefaction ability of foundation. The technology of this project can provide scheme reference and idea reference for similar water project design.
