流塑状地质钻孔灌注桩技术在取水泵站中的应用

Application of Bored Pile Technology in Pumping Station under Flowing-plastic Geological Conditions

摘要:

传统桩基施工方法存在高成本、质量安全隐患大、能源消耗多等问题,为此,以大桥水厂源水工程取水泵站工程为例,提出了一种复杂高含水量流塑状淤泥地质钻孔灌注桩施工技术。该技术采用了优化的泥浆配制方法和具备储浆功能的泥浆循环系统,同时提出了钻孔护筒导向装置以解决垂直度问题,旨在提升施工的可控性和安全性,确保工程质量。

Abstract:

Traditional pile foundation construction methods have problems such as high cost, high risk in quality and safety, and high energy consumption. Therefore, take the water intake pumping station project of Daqiao Water Plant Source Water Project as an example, a bored pile construction technology is proposed for complex high-water-content flowing-plastic silt geological conditions. This technology adopts an optimized mud preparation method and a mud circulation system with a mud storage function. At the same time, a bored pile casing guiding device is proposed to solve the verticality problem. Aims to improve the controllability and safety of construction and ensure the project quality.
