One pump-multi well deep foundation pit tube well synchronous pumping and drainage drawdown device
Disclosed is a one pump-multi well deep foundation pit tube well synchronous pumping and drainage drawdown device. One submerged pump can be used for efficiently and synchronously pumping and draining water of a well group, the number of submerged pumps used is reduced, the distribution of wires and layout of a water drainage pipeline are simplified, the water pumping efficiency of the submerged pump is improved, and energy consumption of synchronous water pumping and drainage of tube wells of the deep foundation pit is reduced. According to the technical scheme, the submerged pump is arranged in a main well. A secondary well water taking pipe with a check valve at the bottom is arranged in a secondary well. A water collecting container is connected with the upper end of the secondary well water taking pipe. A siphon water outlet pipe with a water sealing component at the bottom extends into the secondary well. A siphon condition forming pipe is connected with the water collecting container through a valve. The upper end of the siphon water outlet pipe is also connected with the water collecting container. In this way, water pumped by the submerged pump is injected into the water collecting container through the valve, the water collecting container, the secondary well water taking pipe and the siphon water outlet pipe can exhaust air in the pipes, and a siphon passage is formed between the main well and the secondary well, so that the submerged pump synchronously pumps water of the whole well group.
