Embodiment 1

[0037] A first inspection well 102 and a second inspection well 115 are respectively arranged between the first rain sedimentation tank 100 and the rainwater storage tank 114 and the ground, so as to facilitate the detection of silt in the tank. The sludge in the sewage discharge tank 110 and the initial sedimentation sludge collection tank 103 is collectively collected by the sewage pump.

[0038] A drainage pump 116 is installed at the bottom of the rainwater storage tank 114, and the drainage pump is connected to a drainage pipe 117, and the upper end of the drainage pipe stretches out from the rainwater storage tank 114 top.

Embodiment 2

[0040] Rainwater enters the initial rain sedimentation tank 100 from the water inlet pipe 101. The initial rain sedimentation tank 100 is a reinforced concrete tank. The initial rain sedimentation tank 100 is equipped with a first rain sedimentation sludge collection tank 103. The first rain precipitation sedimentation tank 103 is surrounded by an upper width. The bottom is narrow, and the rainwater pollutants accumulate at the bottom of the pool after being deposited at the bottom of the pool. The initial rain sediment collection tank is surrounded by 111 silica sand permeable bricks. Filtration and sedimentation are carried out simultaneously. Once the pump 108 is discharged, the rainwater can deposit large particles and large silt after entering the initial sedimentation mud pool 103.

[0041] Rainwater enters rear end sedimentation inclined pipe 107 afterwards, and sedimentation inclined pipe 107 is installed on the mounting bracket 106, and the sealing steel plate is arran...

Abstract

The invention provides a buried silica-sand rainwater regulation and storage system which comprises a first rain sedimentation pond and a rainwater storage pond, wherein the first rain sedimentation pond and the rainwater storage pond are mounted side by side under the ground; a horizontally-extending water outlet pipe is mounted at the upper part of the first rain sedimentation pond; and the freeend of the water outlet pipe is connected with a water inlet positioned at the upper part of the rainwater storage pond. According to the buried silica-sand rainwater regulation and storage system, silica-sand water permeable bricks are utilized, so that the filtration process and the sedimentation process can be performed simultaneously; the sedimentation pond is of an inverted-cone structure ofwhich the upper part is large and the lower part is small, and a narrow space is formed at the pond bottom, so that the concentration of solid particles can be facilitated; and after being concentrated together, the solid particles are discharged from the sedimentation pond through sewage pumps, so that the long-time sedimentation of sludge and the solid particles at the pond bottom can be prevented, and the situation of pond pollution and bacteria breeding can be reduced.

Description

technical field [0001] The invention relates to the field of rainwater collection, in particular to an underground silica sand rainwater regulation and storage system. Background technique [0002] Rainwater is natural and non-polluting fresh water. If it is collected, it will be used in many places. Collecting rainwater is a particularly energy-saving and environmentally friendly measure. [0003] There are some storage devices for rainwater in the prior art, but after storage, no subsequent treatment will be performed. In addition, in the prior art, there is no timely discharge method for the silt and sand flowing back into the pool. Contents of the invention [0004] The invention proposes an underground silica sand rainwater regulation and storage system, which solves the problems in the prior art. [0005] Technical scheme of the present invention is realized like this: [0006] The buried silica sand rainwater regulation and storage system includes two primary rai...
