Manual hole digging pile hole bottom gushing water drainage structure and in-hole concrete pouring method
The invention discloses a manual hole digging pile hole bottom gushing water drainage structure and an in-hole concrete pouring method. The manual hole digging pile hole bottom gushing water drainage structure comprises a drainage hole and a drainage pipe, wherein the drainage hole is formed in the pile hole bottom gushing position, a filtering hole is formed in the lower portion of the drainage pipe, an opening is formed in the upper portion of the drainage pipe, the lower part of the drain pipe is inserted into the drain hole, the filter hole is immersed into the drain hole, and the pile hole bottom water gushing position is located in the drainage hole. The method for pouring the concrete in the pile hole of the manual hole digging pile comprises the steps of drain hole digging, drain pipe inserting, coarse sand filling, drain hole sealing and concrete pouring. According to the method, the drainage holes and the drainage pipes are formed in the hole bottom water gushing positions, water in the drainage holes can enter the drainage pipes through the filtering holes, then gushing water is drained out of the pile holes through the drainage pipes, and the situation that when concrete is poured into the pile holes, the water gushing water in the pile holes causes the water-cement ratio of concrete to be increased, and the strength of the concrete is affected is avoided.
本发明公开一种人工挖孔桩孔底涌水排水结构及孔内混凝土浇筑方法，人工挖孔桩孔底涌水排水结构包括排水孔和排水管，所述排水孔设置在桩孔底部涌水位置，所述排水管下部开设滤孔，所述排水管上部设置有开口；所述排水管下部插入至排水孔内，所述滤孔浸没至排水孔内；所述桩孔底涌水位置位于排水孔内。人工挖孔桩桩孔孔内混凝土浇筑方法包括排水孔开挖、排水管安插、粗砂填充、排水孔密封、混凝土浇筑步骤。本发明通过在孔底涌水位置设置排水孔，设置排水管，通过滤孔可以使得排水孔内的水进入到排水管内，进而通过排水管将涌水排出桩孔外部，避免桩孔内浇筑混凝土时桩孔内涌水导致混凝土的水灰比增大影响混凝土的强度。
