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.
