Underground open storage tank

Abstract

The invention discloses an underground open-type storage pond which comprises a pond body. One end of the pond body is provided with a water inlet box culvert in a communicated mode, and the other end of the pond body is provided with a water outlet box culvert in a communicated mode. The pond body is divided into a rainwater pump water accumulation area and a storage area. The rainwater pump water accumulation area is located above the storage area. A rainwater pump and sewage pumps are arranged in the pond body. The rainwater pump is arranged at the end close to the water outlet box culvert. The sewage pumps are arranged on the two sides of the end close to the water inlet box culvert. A water flow inlet groove is formed in the inner bottom face of the pond body. The water flow inlet groove tilts from the rainwater pump to the sewage pumps in a descending mode. Sewage and sediments inside the pond body are discharged outwards through the sewage pumps. According to the underground open-type storage pond, the initial rainwater can be dammed, original running management overhaul workloads of a rainwater pump station are not increased, and the pond bottom pollutant sedimentation degree and decontamination operating difficulty are effectively lowered further.

Description

technical field [0001] The invention relates to the technical field of underground sewage discharge process design, in particular to an underground open storage tank. Background technique [0002] At present, the management unit is very troubled by the management and operation of the storage tanks that have been built. The storage tanks of several pumping stations that are in operation have not been maintained so far. During the flood season, the storage tanks are often full of water and cannot be used anymore. Intercept initial rainwater. At present, most of the storage tanks under construction are underground closed storage tanks, and the main disadvantages are as follows: [0003] 1. There are many equipments, and the maintenance management is difficult; [0004] 2. The underground space is seriously polluted, and maintenance personnel cannot go down to check and repair the storage tanks that are already in operation; [0005] 3. The water quality of combined system is...

AI Technical Summary

Problems solved by technology

[0003] 1. There are many equipments, and the maintenance management is difficult;

[0004] 2. The underground space is seriously polluted, and maintenance personnel cannot go down to check and repair the storage tanks that are already in operation;

[0005] 3. The water quality of combined system is complicated. Although the automatic flushing water system can be used for the sludge at the bottom of the storage tank, auxiliary manual cleaning is still required
