Background
In recent years, the initial rainwater pollution of urban branch system pipelines and the rain overflow pollution of combined system pipelines are increasingly serious, so that serious damage is brought to urban water environment, and even a part of river and lake water systems generate obvious black and odorous phenomena. Therefore, many cities choose to build regulation and storage facilities for controlling the pollution of entering the river in rainy days and assisting the drainage system in upgrading. However, water is incompressible, and to store a certain volume of polluted water under control, an effective storage space with a corresponding volume must be provided, which causes the construction of storage facilities to occupy considerable underground and above-ground space. In urban areas, particularly central urban areas with dense population and buildings, land resources are very tight, land acquisition cost is very high, and site selection of storage and regulation facilities becomes one of the main problems affecting the ground of engineering implementation.
Under the background, the main engineering regulation and storage pool of the regulation and storage facility is built below the river channel according to local conditions to become an innovative technical choice, so that the land area on the ground which is not only nervous can be saved, the river bottom space which is usually idle can be effectively utilized, and the method has great popularization and application potential. However, at present, the engineering exploration and application of building the regulation and storage pond at the river bottom at home and abroad are still rare, and the main reason is that the regulation and storage pond built at the river bottom causes inconvenience in personnel entering and exiting, and great difficulty is brought to manual or mechanical dredging and maintenance. Therefore, it is very necessary to research an anti-silting and maintenance-less land-saving type storage facility.
Disclosure of Invention
The invention aims to provide a siltation-prevention land-saving type storage facility, which solves the problems of difficult desilting and the like caused by arranging a storage pond at the bottom of a river for land saving and provides powerful support for the effective utilization of urban underground space, the adoption of the storage facility to promote water environment treatment and the like.
In order to achieve the purpose, the technical scheme of the invention is as follows: the utility model provides a prevent silting up land-saving type regulation facility, mainly includes regulation pond and subsidiary facility, and the regulation pond sets up in the river bottom, and make full use of river bottom space saves the land to adopt and prevent silting up runway type design, the lower part sets up prevents silting up self-cleaning runner. When water flows in and out, particles such as silt entering the regulation and storage tank keep a higher flow speed in the silt-prevention self-cleaning flow channel, so that sedimentation and sedimentation are not easy to occur. When emptying, particulate matters such as silt entering the regulation and storage tank flow into the water outlet pump room along the water flow, are lifted by the water pump and conveyed to the sewage treatment facility through the water outlet pipeline for treatment, so that the workload of manual cleaning and maintenance of the regulation and storage tank is reduced, the defect that the regulation and storage tank is arranged under water to clean inconveniently is overcome, and multiple effects of land conservation, silt prevention and energy conservation are realized.
Furthermore, the auxiliary facilities are arranged in the ground space of the river bank and comprise a water inlet gate well, a grid room, a water inlet pipeline, a water outlet pump room and a comprehensive functional body, wherein the comprehensive functional body is formed by vertically layering and intensively arranging a power transformation and distribution facility, a ventilation and deodorization facility, a management room and the like.
Furthermore, the anti-silting self-cleaning flow channel arranged at the lower part of the storage tank adopts a rotary reciprocating type, so that smooth water flow can be ensured, and a certain self-cleaning flow rate (more than or equal to 0.75m/s) can be achieved; the width of the flow channel is generally 1-3m, 2 flow channels form a group, a short partition wall is arranged in the middle for division, and the height of the short partition wall (H5-H6) is generally 1.0-3.5 m; and structural partition walls are arranged on two sides of the flow channels and connected with the top and the bottom of the storage regulation pool.

Furthermore, the river bottom regulation and storage tank can be synchronously constructed with river channel revetment engineering, landscape greening engineering, black and odorous river channel treatment engineering, dredging engineering and the like, so that the construction influence can be reduced, and repeated construction in the same area can be avoided.
The operation mode of the regulation and storage facility is as follows: after rainfall begins, sewage to be regulated and stored is connected into the grating room through the inlet gate well, and enters the regulation and storage tank through the inlet pipeline after being pretreated by the grating and the like. When the inlet water reaches the designed highest water level of the regulation and storage tank, the inlet gate is closed, and the inlet water is stopped. After rainfall, the regulated and stored rain sewage is lifted by the water outlet pump room, is connected into a sewage pipeline through the water outlet pipeline and is finally conveyed to a sewage facility for treatment. During the period of water inlet and water discharge of the storage tank, the flow velocity of water flow at the lower part of the flow channel can be kept to be high due to the existence of the self-cleaning flow channel, and silt is brought into a pump pit of the water outlet pump room, so that silt particles are prevented from being deposited in the storage tank. The sediment in the pump pit can be lifted and discharged by a water pump, and a cover plate at the upper part of the pump room can be opened to manually clear and draw when necessary. The regulation pool is mainly in a self-cleaning operation mode, and a small amount of residual sediments at the bottom of the regulation pool can be washed again when the second rain water enters. In addition, if necessary, a water return pipe can be arranged in the water outlet pump room, and the emptying water of the storage tank is returned, so that the storage tank is further flushed.
