Description

a rainwater drainage system

technical field

The utility model relates to the technical field of municipal drainage, in particular to a rainwater drainage system.

Background technique

The urban drainage system is an engineering facility system that treats and discharges urban sewage and rainwater, and is an integral part of urban public facilities. Urban drainage system planning is an integral part of urban overall planning. Among them, the rainwater drainage system is one of the important components of the municipal sewage drainage system.

Authorization announcement number CN201850628U, authorization announcement date is that the Chinese patent of June 01, 2011 discloses urban rainwater sewage discharge system, comprises rainwater sewage pipeline, inspection well, and pipeline and inspection well are connected with sedimentation tank. In heavy rain weather, rainwater sewage enters the sedimentation tank through the rainwater sewage pipe for sedimentation, and the large particles in the rainwater sewage are deposited in the sedimentation tank, so that the final rainwater sewage pipe is not easy to block.

The disadvantage of the existing technology is that under the heavy rain in southern my country, the flow of rainwater on the road is very large. The existing rainwater drainage system mainly drains water through each inspection well corresponding to a wellhead, so that the drainage speed of the inspection well for rainwater is very limited. , when the total amount of rainwater is large, the accumulation speed of rainwater on the road surface will be greater than the speed of these wellheads passing through the rainwater, and the accumulation of rainwater on the road surface will occur. At the same time, the rainwater in the well body is drained through the drainage pipe (rainwater sewage pipe). When the rainwater is large, there is also the problem that the rainwater accumulation speed in the well body is faster than the discharge speed of the drainage pipe, causing the well body to be filled with rainwater, resulting in rainwater on the road surface build up.

Utility model content

The purpose of this utility model is to provide a rainwater drainage system, which solves the problem of slow rainwater discharge in the existing rainwater drainage system, and has the advantages of increasing the discharge speed of rainwater on the road through the permeable ground layer and the diversion channel, and the rainwater well Part of the structure is also made of permeable materials, which improves the efficiency of the municipal rainwater drainage system for the treatment of road water.

The above-mentioned technical purpose of the utility model is achieved through the following technical solutions:

A rainwater drainage system, including a permeable ground layer paved with permeable concrete or permeable bricks, a plurality of diversion channels arranged under the permeable ground layer, and a plurality of rainwater wells connected to the diversion channels, and each rainwater well is connected to a Multiple aqueducts, rainwater wells are connected with drainage pipes, and the drainage pipes are connected with rainwater post-treatment systems. The bottom of the rainwater wells is the bottom of the permeable well made of permeable concrete or permeable bricks.

With the above-mentioned structure, the permeable pavement layer is set so that when there is water accumulation on the road surface, the accumulated water can pass through the permeable pavement and enter the land or the water diversion channel under the permeable pavement at any time. The total flow of rainwater is small, the road surface is not easy to accumulate water, and the rainwater discharge on the road surface is timely and fast. The setting of the diversion channel enables part of the rainwater permeated from the permeable pavement to be diverted into the rainwater well through the diversion channel. The collected rainwater is processed through the conventional rainwater treatment mechanism to realize the effective use and reasonable discharge of rainwater. At the same time, the rainwater under the permeable pavement will not be too much, and the damage to the land caused by excessive rainwater will be reduced. Using multiple diversion channels to connect the rainwater wells is equivalent to increasing the area of the water inlet of the rainwater wells, so that the rainwater wells can receive more rainwater in the same period of time. The bottom surface of the rainwater well is provided with the bottom layer of the permeable well, which is close to and drains part of the rainwater in the permeable well through the drainage pipe, and part of the rainwater in the well is drained through the bottom layer of the permeable well. Make the rainwater in the rainwater well leave the rainwater well faster, and play the role of replenishing groundwater at the same time.

It is further preferred that the permeable layer above the aqueduct is a permeable cover composed of a plurality of independent permeable bricks, the permeable cover and the permeable ground layer are detachably connected, and the permeable cover is provided with at least one dredging through hole that runs through the permeable cover, The dredging through hole communicates the diversion channel with the space above the permeable ground layer.

With the above structure and the arrangement of the permeable cover, it is convenient for the user to maintain the aqueduct. When the user needs to maintain and repair the aqueduct, he only needs to remove the permeable cover. And the permeable cover is provided with a plurality of dredging through holes, when the rainwater flow is large, the rainwater can enter the water diversion channel through the dredging through holes, increasing the rate of rainwater passing through the permeable ground layer. It prevents rainwater from accumulating on the road surface.

It is further preferred that: the permeable ground layer near the permeable cover is provided with a support block for supporting the permeable cover corresponding to the permeable cover, and a side wall of the permeable cover close to the permeable ground layer is provided with a clamping block protruding toward the permeable ground layer, and the permeable ground layer The corresponding clamping block is provided with a clamping groove, and the clamping block is set in cooperation with the clamping groove; when the clamping block is located in the clamping groove and the permeable cover is pressed against the part of the permeable ground layer provided with the clamping groove, the permeable cover is far away from the There is a movable gap between one end of the clamping block and the part of the permeable ground layer far away from the clamping block; a locking block matching the movable gap is provided in the movable gap, and when the locking block is completely located in the movable gap, the permeable cover is provided with a clamping block One end of the water-permeable ground layer is in close contact with the part provided with the clamping groove, so that the clamping block is not easy to leave the clamping groove.

With the above structure, the joint action of the supporting block, the clamping block, the clamping groove and the locking block limits the position of the permeable cover on the permeable road surface. When installing the permeable cover, you only need to place the permeable cover on the support block, and insert the clamping block into the clamping groove. At this time, there is a gap between the permeable cover and the permeable ground layer. Use the locking block to connect the permeable ground layer and The gap between the permeable cover and the filling can make the permeable cover be limited on the ground. At this time, the permeable cover can only move along the axis of the clamping groove. When all the permeable covers are installed, the permeable covers will abut against each other, so that the permeable cover is also limited on the axis of the clamping groove, that is, the permeable cover completely restricted. The water permeable cover of this structure is easy to disassemble, only need take out the locking block, can take out a separate water permeable cover, it is convenient for the user to repair the separate water permeable cover and maintain the aqueduct below the water permeable cover.

It is further preferred that: the part of the side wall of the aqueduct close to the ground is a diversion layer made of permeable concrete or permeable bricks.

With the above-mentioned structure, the part near the bottom of the aqueduct is made of permeable material. When the water surface in the aqueduct is located near the ground, it means that the water flow in the aqueduct is large and the flow rate is large. When it enters the rainwater well, this part of the rainwater It is not easy to be discharged in time. Through the setting of the diversion layer, the rainwater whose liquid level is located in the upper half of the aqueduct can be discharged directly from the aqueduct, reducing the amount of rainwater that needs to be discharged from the rainwater well and speeding up the rainwater entering the rainwater canal The fast discharge speed makes the rainwater in the rainwater well not easy to accumulate.

It is further preferred that: the middle and upper part of the rainwater well is connected with a plurality of diversion pipes, and the diversion pipes connect the interior of the rainwater well with the rainwater post-treatment system or other municipal drainage systems; all the diversion pipes make the water flow in the diversion pipe only toward the direction away from the rainwater One-way valve for flow in the well direction.

With the above structure and the setting of the diversion pipe, there is more rainwater in the rainwater well. At this time, the speed of rainwater leaving the rainwater well is slower than the speed of new rainwater entering the rainwater well. At this time, the rainwater that cannot be discharged in time can leave the rainwater through the diversion pipe. The rainwater is transferred to the post-treatment device of the rainwater drainage system or other municipal drainage systems through the diversion pipe, reducing the pressure of the municipal rainwater drainage system and speeding up the treatment and discharge of rainwater. The setting of the one-way valve makes it difficult for the water flow in the shunt pipe to flow back into the rainwater well, which reduces the pollution of the water in the rainwater well by the wastewater in other municipal drainage systems.

It is further preferred that: the top of the rainwater well is provided with a drainage layer made of water-permeable material on the side wall.

With the above-mentioned structure and the setting of the drainage layer, when the liquid level in the rainwater well rises to a high level, it means that the drainage rate of the rainwater well at this time cannot completely discharge the newly entered rainwater. , the water in the rainwater well that cannot be discharged by the shunt pipe, drain pipe, and bottom of the permeable well leaves the rainwater well through the drainage layer, so that the rainwater in the rainwater well can be discharged in time, so that the rainwater well can play its drainage function normally and smoothly . And the drainage layer is set above the rainwater well so that when the amount of rainwater in the rainwater well is not large, most of the water flow is discharged in a normal way, and the drainage layer only plays a role when the amount of rainwater in the rainwater well is large, ensuring that the rainwater is kept safe when the amount of rainwater is small. Normal handling and normal discharge.

In summary, the utility model has the following beneficial effects: the rainwater on the road surface can infiltrate into the permeable road surface in a timely manner through the permeable road surface and the water diversion canal, part of the rainwater enters the land, and part of the rainwater enters the water diversion canal. The rainwater is drained into the rainwater well and discharged through the drainage channels in the rainwater well and the bottom of the permeable well. Channels for draining rainwater into stormwater wells have been added. It prevents rainwater from accumulating on the bottom. The setting of the diversion layer enables part of the rainwater to be directly discharged into the soil layer through the diversion layer when the water flow in the aqueduct is large, which accelerates the speed of the rainwater drainage system to discharge rainwater. The distributing pipe is arranged so that when rainwater accumulates in the rainwater well, part of the rainwater can leave the rainwater well through the diverging pipe, which increases the speed at which the rainwater well discharges rainwater. The setting of the support block, the clamping groove, the clamping block, and the locking block realizes the limit of the permeable cover through the clamping structure, making the permeable cover easy to disassemble, making the replacement and repair of the permeable cover and the maintenance of the aqueduct convenient. The setting of the drainage layer makes it possible for the rainwater to leave the interior of the rainwater well through the drainage layer when the amount of water in the rainwater well is large, increasing the channels for the drainage of rainwater in the rainwater well, making it difficult for the rainwater to accumulate in the rainwater well, and increasing the discharge of rainwater from the rainwater well speed.

The surface of the permeable cover 7 has a plurality of dredging through holes 8, and the dredging through holes 8 communicate the aqueduct 2 with the space above the permeable cover 7.

Referring to Figure 2 and Figure 3, the permeable ground layer 1 is located at the permeable cover 7 and is provided with a support block 9 for supporting the permeable cover 7, and the permeable cover 7 is provided with a clamping block protruding toward the permeable ground layer 1 near the side wall of the permeable ground layer 10. The corresponding clamping block 10 on the permeable ground layer 1 is provided with a clamping groove 11 that cooperates with the clamping block 10 . The water-permeable ground layer 1 is pressed against, and at this time, there is a gap between the water-permeable cover 7 and the part of the water-permeable ground layer 1 away from the engagement groove 11 . The gap between the permeable cover 7 and the permeable ground layer 1 is filled with locking blocks 12 . The locking block 12 and the permeable cover 7, and the locking block 12 and the permeable ground layer 1 are tightly pressed. At this time, the permeable cover 7 and the permeable ground layer 1, and the permeable cover 7 and the locking block 12 are also tightly pressed, so that the permeable cover 7 is limited on the permeable ground layer 1.

Referring to FIG. 1 , one end of the aqueduct 2 communicates with the middle and upper part of the rainwater well 3 , and the part of the aqueduct 2 close to the rainwater well 3 is lower than the part of the aqueduct 2 away from the rainwater well 3 . Each rainwater well 3 is connected with a plurality of diversion channels 2 . Part of the side wall of the aqueduct 2 near the bottom is a diversion layer 13 made of permeable concrete.

Referring to Fig. 1, the bottom of the rainwater well 3 is a permeable well bottom 6 laid with permeable concrete or permeable bricks.

Use process:

During heavy rain, rainwater falls on the ground, and part of the rainwater permeates the permeable ground layer 1 and enters the land 16 below the permeable ground layer 1 to dredge the rainwater on the ground and replenish groundwater at the same time. Part of the rainwater penetrates the permeable ground layer 1 and the permeable cover 7 and then enters the aqueduct 2 below the permeable cover 7 . Part of the rainwater enters the water diversion channel 2 through the dredging through hole 8 on the permeable cover 7 .

The water flow entering the aqueduct 2 enters the rainwater well 3 along the aqueduct 2 . When the rainwater flow rate is so large that the liquid level of the water flow in the aqueduct 2 is at the diversion layer 13 , the rainwater at the diversion layer 13 will penetrate the diversion layer 13 and enter the surrounding land 16 . Part of the water flow in the aqueduct 2 is directly discharged into the land 16 .

After the rainwater entered the rainwater well 3, part of the rainwater infiltrated into the land 16 through the bottom 6 of the permeable well. Part of the rainwater leaves the rainwater well 3 through the drainage pipe 4, and enters the post-processing device (not shown in the figure) to effectively treat the rainwater, and use or discharge the rainwater.

When the speed of entering rainwater in the rainwater well 3 is faster than the speed of rainwater discharge, the rainwater in the rainwater well 3 will gradually rise. The water flow that cannot be discharged in time by the rainwater well 3 itself is discharged to the post-treatment device or other municipal drainage systems (not shown in the figure) through the diversion pipe 5 . Use other municipal sewer systems to share the current pressure on the stormwater drainage system. Ensure that rainwater on the road surface can be drained in time.

When the water surface in the rainwater well 3 rises to the drainage layer 15, this part of the water flow penetrates the drainage layer 15 and enters the land 16, and this part of the diversion pipe 5, the drainage pipe 4, and the bottom layer of the permeable well 6 cannot be discharged in time. The water flow is drained into the land 16 . The above is the rainwater discharge process of the rainwater discharge system recorded in the utility model.
