Background
The sponge city is a new generation city rain and flood management concept, and the city can be like a sponge and has good elasticity in the aspects of adapting to environmental changes, coping with natural disasters caused by rainwater and the like. Specifically, water is absorbed, stored, permeated and purified during raining, and the stored water is released and utilized when needed, so that the free migration of rainwater in cities is realized.
In sponge cities, rainwater pumping stations and regulation reservoirs are indispensable. The rainfall can be effectively collected, so that the effects of regulating and accumulating, preventing flood and reducing peak can be achieved in the whole area, and the rainfall can be discharged to a sewage plant for deep treatment and recycling. The following detailed description is given respectively.
The main function of the rainwater pump station is to lift the rainwater in the area with lower topography or the area where the drainage system can not drain by means of the self-flowing of the topography, so as to ensure that the rainwater can be normally drained and prevent the occurrence of ponding and flooding. The pump device is arranged in the pump room, after rainwater enters the pump room, the water is lifted to a certain height through the action of the pump and then is discharged into a rainwater pipe network or directly discharged into a receiving water body.
The main function of the regulating reservoir is to regulate the discharge of rainwater. Under the condition of large rainwater, the drainage amount of the rainwater can exceed the bearing capacity of a downstream drainage pipe network or a receiving water body, and the rainwater can be temporarily stored in a regulating and accumulating pond and then slowly drained, so that downstream flooding caused by overlarge rainwater drainage amount is avoided. In addition, the water flow speed of the regulating and accumulating pond can be slowed down, so that pollutants have the opportunity to settle, and a certain water quality improvement effect is achieved.
In general, the rainwater pumping station and the regulating reservoir are built together, so that the functional advantages of the rainwater pumping station and the regulating reservoir can be combined, and more efficient and stable rainwater discharge can be realized, and the advantages are included in particular.
(1) And (3) overall management: the construction can realize the integral management and operation and maintenance of facilities, improve the operation efficiency and reduce the complexity of management and maintenance.
(2) Optimizing space utilization: through integrated design, space can be utilized better, area is reduced, and construction cost is reduced.
(3) The drainage efficiency is improved: under the condition of large rainfall, the rainwater pump station can lift rainwater to the regulation pond, and the rainwater pump station slowly discharges through the regulation pond, reduces the impact of rainwater on a downstream drainage system, and improves overall drainage efficiency.
(4) The risk of flooding is reduced: after the pump station lifts the accumulated water, the regulating and accumulating water tank can temporarily store rainwater, delay discharge and help to relieve urban flooding under the condition of heavy rainfall.
(5) Water quality improvement: the regulating and accumulating water tank can buffer rainwater and simultaneously can reduce the speed of water flow, so that pollutants in the rainwater have more precipitation opportunities, and the discharged water quality is improved.
(6) The energy consumption is saved: under the condition that a pump station and a regulating reservoir are integrated, the running state of the pump can be reasonably regulated through intelligent management, such as rainfall prediction, water level control and the like, and energy is saved.
In the process of combining a rainwater pump station and a regulating water tank, the equipment layout and the water pipeline arrangement need to be considered in view of the working principle and the operation efficiency of facilities. One common water line arrangement is where rainwater is pumped from a pool of a rainwater pump station to a storage tank by a lift pump, wherein the water outlet pipeline is typically directly connected to the storage tank above the highest water level by a side wall. However, since the water hammer phenomenon occurring when the pump is stopped is not controlled, the bottom of the regulating reservoir is severely eroded and worn.
In order to solve the above technical problems, there is a need in the related art for a water outlet pipe for a rainwater pump station and a storage tank.
