Description

Technical Field

[0001] The utility model belongs to the technical field of rainwater collection, and in particular relates to a sponge city rainwater collection structure. Background Art

[0002] In southern cities with heavy rainfall, there are many rainwater collection structures, such as permeable pavements, which collect the rainwater that seeps through.

[0003] However, traditional permeable pavements mostly use polyurethane-based permeable pavements, permeable concrete, permeable porous asphalt, permeable bricks and gravel roads.

[0004] This type of permeable pavement has a decent rainwater penetration effect when it rains lightly. However, once it rains heavily or even rainstorms, the rainwater will surge in a short period of time. The permeable pavement cannot penetrate the rainwater quickly enough to drain the accumulated water, thus causing rainwater flooding. Summary of the invention

[0005] The purpose of the utility model is to provide a sponge city rainwater collection structure to address the problems existing in the prior art, and to solve the problem that when heavy rain occurs in a short period of time on the existing permeable pavement, rainwater is not collected quickly enough and infiltration is slow, which easily leads to waterlogging.

[0006] To achieve the above purpose, the utility model adopts the following technical solution: a sponge city rainwater collection structure, including a water collection layer laid on the bottom layer, hollow side embankments arranged on both sides of the water collection layer, an aggregate layer and a permeable pavement layer laid on the water collection layer from bottom to top; wherein,

[0007] The water collecting layer comprises a plurality of plate frames connected in series, the inner bottom wall of the plate frame is integrally formed with a middle support seat in contact with the inner top wall of the plate frame, the top wall of the plate frame is provided with a plurality of water inlets vertically penetrating the top wall of the plate frame, and both sides of the plate frame are fixedly installed with butt pipes extending to the inside of the hollow side dike;

[0008] A drainage pipe is arranged on one side of the hollow side embankment away from the butt pipe, a flooding port is arranged on the oblique side surface of the hollow side embankment facing the water collection layer, and a water delivery pipe is arranged at the other end of the drainage pipe.

[0009] When it rains, if the amount of rain is not large, the rainwater will directly pass through the permeable pavement layer and the aggregate layer and then penetrate into the lowest water collection layer, and then enter the hollow side embankments on both sides through the docking pipes, and the rainwater will be collected by water pipes. When facing heavy rain or heavy rain, the rainwater that cannot penetrate into the permeable pavement layer in time will enter the hollow side embankment through the flooding port before overflowing the hollow side embankment, and then be collected, thereby greatly improving the speed of rainwater collection, that is, it can effectively collect rainwater while effectively avoiding road waterlogging.

[0010] Optionally, the length of the middle support seat is equal to the length of the plate frame, and the middle support seat is located in the middle of the plate frame.

[0011] The middle support seat effectively provides support force to the plate frame, reducing the possibility of the middle of the plate frame breaking due to heavy pressure.

[0012] Optionally, the number of the butt joints on both sides of the plate frame is not less than 2, and the butt joints are attached to the inner bottom wall of the plate frame.

[0013] The butt-joint pipe is attached to the inner bottom wall of the plate frame, and can drain the accumulated water in the plate frame as much as possible.

[0014] Optionally, the length of the hollow side embankment is equal to the length of the plate frame, and the slope of the hollow side embankment is located higher than the top surface of the permeable pavement layer.

[0015] The slope is higher than the top surface of the permeable pavement layer, which can effectively prevent sand and gravel on the road surface from entering the hollow side embankment through the flooding port at the upper end of the slope.

[0016] Optionally, a docking port is provided on a side of the hollow side embankment facing the plate frame, and the docking tube passes through the docking port.

[0017] The opened docking ports correspond to the docking pipes, making it easier for workers to splice the hollow side dike with the water collection layer during installation.

[0018] Optionally, the flooding outlet is composed of an outer outlet and an inner outlet in sequence from the outside of the hollow side dike to the inside of the hollow side dike, the width of the outer outlet is greater than the width of the inner outlet, the lengths of the outer outlet and the inner outlet are equal, and an intercepting mesh plate is embedded in the outer outlet.

[0019] The flooding outlet formed by the outer opening and the inner opening can make it easier to install the interception net plate, and the interception net plate can effectively intercept the garbage floating on the water surface.

[0020] Optionally, a mesh mat is laid between the water-collecting layer and the aggregate layer.

[0021] The mesh pad can effectively prevent aggregates in the aggregate layer from entering the water collection layer through the water inlet, and can also prevent the aggregates from blocking the water inlet.

[0022] Optionally, the permeable pavement layer is paved with a plurality of permeable bricks, the permeable bricks are evenly provided with permeable holes vertically penetrating the permeable bricks, and the permeable bricks are evenly and integrally formed with a plurality of partitions on both sides along the length direction.

[0023] The permeable bricks with permeable holes can penetrate rainwater more quickly. At the same time, the added partitions can leave gaps between the permeable bricks, assisting the permeable holes to quickly penetrate rainwater into the aggregate layer below.

[0024] Compared with the prior art, the beneficial effects of the utility model are:

[0025] 1. When the rainfall is not heavy, rainwater will directly penetrate into the water collection layer at the bottom through the permeable pavement layer and the aggregate layer, and then enter the hollow side dikes on both sides through the butt joint pipes. The rainwater is collected by the water pipes. The permeable pavement layer and the aggregate layer can effectively filter the rainwater. When facing heavy rain or heavy rain, the rainwater that cannot be penetrated by the permeable pavement layer in time will enter the hollow side dike through the flooding port before overflowing the hollow side dike, and then be collected, thereby greatly improving the speed of rainwater collection, that is, it can effectively collect rainwater and effectively avoid road 1. The situation of road waterlogging; 2. The middle support seat effectively provides support for the plate frame, improves the load-bearing capacity of the middle part of the plate frame, and then improves the service life of the road; 3.

[0036] The following will be combined with the drawings in the utility model to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as "middle", "upper", "lower", "left", "right", "inside" and "outside" are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0038] like Figure 1 —4, the specific scheme of the embodiment is as follows: a sponge city rainwater collection structure, including a water collection layer 1 laid on the bottom layer, hollow side embankments 2 arranged on both sides of the water collection layer 1, an aggregate layer 4 and a permeable pavement layer 5 laid on the water collection layer 1 from bottom to top.

[0039] It should be noted here that the sponge city rainwater collection structure involved in this application is mainly used on sidewalks or non-motorized vehicle roads.

[0040] The water collecting layer 1 comprises a plurality of plate frames 11 connected in series, the inner bottom wall of the plate frame 11 is integrally formed with a middle support seat 12 in contact with the inner top wall of the plate frame 11, the top wall of the plate frame 11 is provided with a plurality of water inlets 13 vertically penetrating the top wall of the plate frame 11, and both sides of the plate frame 11 are fixedly installed with butt pipes 14 extending to the inside of the hollow side dike 2;

[0041] A drainage pipe 22 is provided on one side of the hollow side dike 2 away from the butt joint 14 , a flooding port 23 is provided on the oblique side of the hollow side dike 2 facing the water collection layer 1 , and a water delivery pipe 7 is provided at the other end of the drainage pipe 22 .

[0042] like Figure 1As shown, when the rainfall is not large, the rainwater will directly pass through the permeable pavement layer 5 and the aggregate layer 4 and then penetrate into the water-collecting layer 1 at the bottom, and then enter the hollow side embankments 2 on both sides through the connecting pipe 14, and then be collected by the water pipe 7, wherein the permeable pavement layer 5 and the aggregate layer 4 can effectively filter the rainwater. When facing heavy rain or heavy rain, the rainwater that cannot penetrate the permeable pavement layer 5 in time will enter the hollow side embankment 2 through the flooding port 23 before overflowing the hollow side embankment 2, and then be collected, thereby greatly improving the rainwater collection speed, that is, it can effectively collect rainwater while effectively avoiding road waterlogging.

[0043] In this embodiment, the length of the middle support seat 12 is equal to that of the plate frame 11, and the middle support seat 12 is located in the middle of the plate frame 11. The middle support seat 12 effectively provides support force to the plate frame 11, reducing the possibility of the middle of the plate frame 11 being broken due to heavy pressure.

[0044] Among them, the number of the butt joints 14 on both sides of the plate frame 11 is not less than 2, and the specific number is determined according to the length of the plate frame 11. Generally, the distance between two butt joints 14 does not exceed 1.5 meters, and the butt joints 14 are close to the inner bottom wall of the plate frame 11.

[0045] The butt joint 14 is close to the inner bottom wall of the plate frame 11 and can drain the accumulated water in the plate frame 11 as much as possible.

[0046] In this embodiment, the length of the hollow side embankment 2 is equal to the length of the plate frame 11 , and the inclined surface of the hollow side embankment 2 is located at a position higher than the top surface of the permeable pavement layer 5 .

[0047] The inclined surface is higher than the top surface of the permeable pavement layer 5 , which can effectively prevent sand and gravel on the pavement from entering the hollow side embankment 2 through the flooding port 23 at the upper end of the inclined surface.

[0048] See also Figure 3 A butt joint 21 is provided on one side of the hollow side embankment 2 facing the plate frame 11, and the butt joint pipe 14 passes through the butt joint 21. The butt joint 21 corresponds to the butt joint pipe 14, so that it is easier for workers to splice the hollow side embankment 2 with the water collection layer 11 during installation.

[0049] The flooding port 23 is composed of an outer port and an inner port from the outside of the hollow side dike 2 to the inside of the hollow side dike 2 in sequence. The width of the outer port is greater than the width of the inner port, and the length of the outer port is equal to that of the inner port. An interception mesh plate 6 is embedded in the outer port.

[0050] The flooding port 23 formed by the outer port and the inner port can more conveniently install the interception net plate 6, and the interception net plate 6 can effectively intercept the garbage floating on the water surface.

[0051] It should be noted that in order to prevent the aggregates in the aggregate layer 4 from entering the water collection layer 1 through the water inlet 13 and to prevent the aggregates from blocking the water inlet 13, a mesh mat 3 is laid between the water collection layer 1 and the aggregate layer 4.

[0052] See also Figure 1 or Figure 4 The permeable pavement layer 5 is paved with a plurality of permeable bricks 51, on which permeable holes 52 vertically penetrating the permeable bricks 51 are evenly opened, and a plurality of partitions 53 are evenly integrally formed on both sides of the permeable bricks 51 along the length direction.

[0053] The permeable bricks 51 with the permeable holes 52 are more quickly penetrated by rainwater. Meanwhile, the added partitions 53 can leave gaps between the permeable bricks 51 to assist the permeable holes 52 in quickly penetrating rainwater into the aggregate layer 4 below.

[0054] The working principle of the above embodiment is: when the rainfall is not large, the rainwater will directly pass through the permeable pavement layer 5 and the aggregate layer 4 and then penetrate into the water-collecting layer 1 at the bottom, and then enter the hollow side embankments 2 on both sides through the docking pipe 14, and the rainwater will be collected by the water pipe 7. When facing heavy rain or heavy rain, the rainwater that cannot penetrate the permeable pavement layer 5 in time will enter the hollow side embankment 2 through the flooding port 23 before overflowing the hollow side embankment 2, and then be collected.

[0055] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
