Drainage construction method for soft soil texture deep foundation pit
The invention relates to a drainage construction method for a soft soil texture deep foundation pit. The drainage construction method comprises the following steps that S1, foundation pit supporting pile arranging work is completed; s2, arranging a drainage open trench; s3, earth excavation of the soft soil stratum; s4, a gravel layer is laid on the bottom of the foundation pit; s5, a drainage blind pipe main pipe and a drainage blind pipe branch pipe are pre-buried in the gravel layer; s6, water collecting pits are formed in the four corners of the gravel layer, drainage main pipes are pre-buried around the gravel layer, the drainage main pipes are connected nearby the drainage blind pipe main pipes, the drainage main pipes are connected into the water collecting pits, and the drainage main pipes are provided with gradients and slope direction water collecting pits; and S7, a drainage pump is arranged in the water collection pit. Water in the soft soil stratum can be separated out to the gravel layer after a certain time, the gravel layer is high in water permeability, the water in the gravel layer is organized and efficiently discharged into the drainage main pipe through a sponge drainage system formed by the drainage blind pipe main pipe and the drainage blind pipe branch pipes, and then the water is converged to a water collection pit. And finally, the water is lifted to the open drain through the drainage pump to realize drainage.
本发明涉及一种用于软土地质深基坑的排水施工方法，包括以下步骤：S1：完成基坑支护排桩工作；S2：设置排水明沟；S3：软土地质层土方开挖；S4：基坑底部上铺设砾石层；S5：砾石层中预埋排水盲管主管与排水盲管支管；S6：在砾石层的四个角设置集水坑，砾石层的四周预埋排水主管，排水盲管主管就近接入排水主管，排水主管接入集水坑，且排水主管设置有坡度，坡向集水坑；S7：在集水坑内设置排水泵。软土地质层的水在一定时间后会析出至砾石层，而砾石层透水性强，再通过排水盲管主管与排水盲管支管形成的海绵排水系统有组织、高效率地将砾石层的水排放至排水主管内，继而汇流至集水坑，最终通过排水泵将水提升至排水明沟实现排水。
