Deep multistage dynamic foundation pit precipitation system and precipitation method thereof
The invention discloses a deep multistage dynamic foundation pit precipitation system and a precipitation method of the deep multistage dynamic foundation pit precipitation system, and relates to thetechnical field of civil engineering construction. The deep multistage dynamic foundation pit precipitation system is characterized in that the deep multistage dynamic foundation pit precipitation system comprises a foundation pit, a sedimentation tank, a booster pump, an annular drainage main pipe, a water delivery main pipe, a precipitation pipe well, a light well point, a well point pump, an annular drainage branch pipe, a water tank and a desiccation pipe well, wherein the foundation pit is provided with steps. The precipitation pipe well is connected with the annular drainage main pipe through a first branch pipe to form a one-stage pipe well precipitation system. The water tank is connected with the annular drainage main pipe through a second branch pipe to form a secondary light well point precipitation system. The desiccation pipe well and the booster pump form a three-stage pipe well desiccation system. According to the precipitation system, an open deep multistage precipitation mode is formed by a primary precipitation system and a secondary precipitation system, the pipe well pumping lift can be reduced, and drainage flow is greatly increased. Due to the combination withthe three-stage pipe well desiccation system, the drainage efficiency is improved, and the water-free operation of the foundation pit is ensured. A drainage and desiccation system has little interference on engineering construction, is low in engineering cost and has strong applicability.
本发明公开了一种深层多级动态的基坑降水系统及其降水方法，涉及土建施工技术领域，其技术方案要点是：包括设有台阶的基坑、沉淀池、增压泵、环形排水总管、输水总管、降水管井、轻型井点、井点泵、环形排水分管、水箱和疏干管井；降水管井通过第一支管与环形排水总管连接，构成一级管井降水系统；水箱通过第二支管与环形排水总管连接，构成二级轻型井点降水系统；疏干管井与增压泵构成三级管井疏干系统。该降水系统由一级降水体系和二级降水体系构成敞开式深层多级降水模式，能降低管井泵送扬程，极大提高排水流量，并结合三级管井疏干系统，提升排水效率，保证基坑无水作业；该排水及疏干系统对工程施工干扰少，工程造价低，具有较强的适用性。
