Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, embodiments of the present invention will be further described below with reference to the accompanying drawings.

Please refer to fig. 1 to 3, an embodiment of the present invention provides a rainwater storage system, including inspection shaft 1 and upstream rainwater pipe network, be equipped with overflow wall 2 in the inspection shaft 1, so that inspection shaft 1 forms the interior space of the shape of falling the U, 2 both sides of overflow wall are water storage chamber 11 and drainage chamber 12 respectively, water storage chamber 11 through upstream inlet tube 3 with upstream rainwater pipe network intercommunication, overflow wall top elevation is above the pipe top elevation of upstream rainwater pipe network, drainage chamber 12 and low reaches drain pipe 4 intercommunication. The overflow wall 2 is provided with a water passing port 21 in a penetrating manner, the water passing port 21 is positioned above the bottom wall of the water storage cavity 11 so that a deposition groove 11a is formed at the bottom of the water storage cavity 11, and the water passing section area of the upstream water inlet pipe 3 is larger than that of the water passing section area at the water passing port 21; the water passing port 21 is correspondingly provided with a filtering structure for filtering the substances flowing through the water passing port 21.

When the rainfall is large, the water level rises to the water passing port 21, fallen leaves and sundries can be intercepted by the filtering structure, and as the water passing cross-sectional area of the water passing port 21 is smaller than that of a rainwater pipe, specifically, the water passing cross-sectional area of the water passing port 21 is 1/10-1/8 of that of the upstream rainwater pipe, the water level continues to rise to the top of the overflow wall, and rainwater and floating objects on the water level flow over the overflow wall 2 and freely fall and are discharged to the downstream rainwater pipe at high speed. After the peak flow of the municipal pipe network is passed, when the rainwater level drops below the top of the overflow wall, because the height of the top of the overflow wall is higher than the height of the pipe bottom of the upstream rainwater pipe network, the water storage cavity 11 of the inspection well 1 and the upstream rainwater pipe network can be used as a part of volume for regulating and storing rainwater, and the rainwater slowly flows into the downstream water outlet pipe through the water passing port 21, so that the drainage pressure of the municipal rainwater pipe network is reduced when the peak flow is passed. Meanwhile, impurities filtered by the filtering structure can be deposited in the deposition groove 11a, so that the water passing opening 21 is prevented from being blocked.

In this embodiment, the top of the overflow wall is flush with the top of the upstream rainwater pipe network, so that the rainwater storage volume is increased, and the volume of the upstream rainwater pipe network is fully utilized. In order to facilitate the drainage of rainwater and fine impurities in the inspection well 1, the pipe bottom of the upstream water inlet pipe 3 and the pipe bottom of the downstream water inlet pipe are flush with the bottom wall of the drainage cavity 12, and the bottom wall of the water storage cavity 11 is positioned below the bottom wall of the drainage cavity 12. The inspection well 1 is provided with a falling prevention plate 5 and a manhole maintenance cover plate 6 at the well mouth, and the falling can be prevented after the manhole maintenance cover plate 6 is damaged.

Further, clearance box 7 opening up and with settling basin 11a looks adaptation, clearance box 7 demountable installation in settling basin 11a, sedimentation such as filterable debris, heavy mud in the rainwater is in clearance box 7, and the workman will clear up box 7 and take out, can clear up debris, heavy mud etc. in the cross well. One side of the cleaning box 7 close to the water passing port 21 is connected with a first filter screen 71 opposite to the water passing port 21, and a second filter screen is arranged at the water passing port 21 to form the filtering structure. Through corresponding being provided with filtration at water passing opening 21, can effectively filter, avoid debris such as debris, earth to get into drainage chamber 12. The cleaning box 7 is connected with a vertical connecting rod 72, the connecting rod 72 extends to the wellhead of the well body, a worker can take out the cleaning box 7 conveniently by moving the connecting rod 72, and the first filter screen 71 is fixedly connected with the connecting rod 72. Debris, soil and other residues in the early stage rainwater can be removed by lifting the cleaning box 7, and the pollution to rivers and the Han dynasties caused by the debris and the soil can be reduced.

The connecting rod 72 interval is equipped with a plurality ofly, and is adjacent be connected with horizontal stiffener 73 between the connecting rod 72, and the deposit has back such as debris, heavy mud in the clearance box 7, and the pressure grow that the clearance box 7 received through being connected with stiffener 73, can strengthen the intensity of connecting rod 72, through being equipped with a plurality of connecting rods 72, connecting rod 72 top is connected with handle 74 to supply the workman to hold, be convenient for take out clearance box 7.

In the leaf falling season, sanitation workers clean road sundries, partial leaves and sundries can fall into a rainwater inlet, at the early stage of rain or in the rainstorm season, when rainwater accumulated water and drainage of the road are not smooth, the rainwater flows to mix with impurity sundries to enter the inspection well 1, the water level rises to the water passing opening 21 along with the increase of rainfall, and the fallen leaves and the sundries can be intercepted by the filtering structure. Because the water passing section area of the water passing opening 21 is smaller than that of the rainwater pipe, the water level continues to rise to the top of the overflow wall, rainwater and floating objects on the water surface flow over the overflow wall 2, and the free falling bodies fall at high speed to discharge fine suspended matters to the downstream rainwater pipe. After the peak flow of the municipal pipe network is over, when the rainwater level drops below the top of the overflow wall, the rainwater slowly flows into the downstream water outlet pipe through the water passing port 21, the water storage cavity 11 of the inspection well 1 and the upstream rainwater pipe network can be used as a part of volume for regulating and storing the rainwater, and the drainage pressure of the municipal rainwater pipe network is reduced when the peak flow is over. When the workers clean the box, the manual maintenance cover plate is opened, the cleaning box 7 is lifted up by lifting the handle 74 on the connecting rod 72, and sundries and sludge in the cleaning box 7 are cleaned.

Generally, the rainwater pipe network pipe diameter on upper reaches is very big, and the volume is very big, the utility model discloses a set up overflow wall 2 in inspection shaft 1, make the rainwater pipe network volume on the water storage chamber 11 of overflow wall 2 and upper reaches as the regulation volume to reduce the rainwater regulation volume, can not set up the rainwater regulation pond even, do not need electric control, be difficult for becoming invalid, reduce artifical maintenance cost, rainwater retaining pond volume construction cost, handle and maintenance cost. Debris, soil and other residues in the early stage rainwater can be removed by lifting the cleaning box 7, and the pollution to rivers and the Han dynasties caused by the debris and the soil can be reduced.
