Pile hole retaining wall construction method suitable for bridge road construction
The invention provides a pile hole retaining wall construction method suitable for bridge road construction, which comprises the following steps: leveling a site, paying off and determining the position of a pile hole, digging drainage ditches around the ground of the hole, timely removing surface water around the pile hole, draining and ventilating, accurately lofting the position of the pile hole, correcting the hole wall and mounting a retaining wall template. The position of the center of the pile hole is corrected, the roundness defined by the formwork is corrected, the position for pouring concrete needs to be reserved at the top of the formwork, a wall protection formwork is poured, watering maintenance is conducted, and after the formwork is removed, according to different geological conditions of the pile hole excavation environment, next-section water drainage, air supply and earth cutting circulation construction is conducted till the pile hole reaches the preset depth. Compared with a traditional construction scheme, according to the technical scheme, the design is optimized according to the situation that much underground water exists in the soil in the construction process, the underground water in the soil can be effectively discharged, surface water is pretreated, normal construction operation is prevented from being disturbed by the surface water, the construction efficiency of pile holes is improved, and the construction period is shortened on the premise that safety is guaranteed.
本发明提供了一种适用于桥梁道路施工的桩孔护壁施工方法，包括以下步骤：平整场地，放线并确定好桩孔位置，孔口地面四周挖好排水沟，及时排除桩孔周围的地表水，排水通风，精确放样桩孔位置，修正孔壁，安装护壁模板，矫正桩孔中心的位置，并矫正模板围成的圆度，模板顶部应留出浇筑混凝土的位置，浇筑护壁模板并浇水养护，拆除模板后，针对桩孔挖掘环境的不同地质条件，进而进行下节排水送风挖土循环施工，直至桩孔达到预定深度。相较于传统施工方案，本技术方案在施工过程中针对土壤中地下水较多的情形优化设计，可有效排出土壤中的地下水，并对地表水进行预处理，避免其干扰到正常的施工作业，提升桩孔的施工效率，确保安全的前提下缩短工期。
