Description

Technical Field

[0001] This utility model relates to the field of permeable concrete technology, specifically a permeable concrete structure with rainwater collection function. Background Technology

[0002] Permeable concrete pavement is a permeable road material with a certain porosity, which can achieve drainage, noise reduction and water infiltration effects. It can improve surface circulation, facilitate traffic safety, protect the ecological environment and solve the negative impacts of large-scale modern urban construction.

[0003] Most existing concrete pavements do not have rainwater collection capabilities, which means that rainwater cannot be drained in time during heavy rain. At the same time, it cannot be collected and utilized, which leads to the waste of water resources in some dry climates. To address this, we propose a permeable concrete structure with rainwater collection capabilities to solve the problems mentioned in the background. Utility Model Content

[0004] The purpose of this invention is to provide a permeable concrete structure with rainwater harvesting function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a permeable concrete structure with rainwater collection function, comprising a road base layer, a water storage tank, a permeable concrete layer, and a pavement layer arranged sequentially from bottom to top. The top of the road base layer is also provided with two roadside layers. The roadside layers are in close contact with the water storage tank, the permeable concrete layer, and the pavement layer. Water pipes are connected to both sides of the water storage tank. The top of the water storage tank has a plurality of first infiltration holes arranged in a matrix. The interior of the roadside layers has a first water passage cavity and a second water passage cavity respectively arranged from top to bottom. The second water passage cavity is connected to the permeable concrete layer by a plurality of second infiltration holes. A plurality of filter elements are installed equidistantly on opposite sides of the two roadside layers and at positions corresponding to the first water passage cavity.

[0006] The filter element includes a cylinder with a threaded portion on its outer surface. A filter cylinder and an annular plate are fixedly connected to the left and right ends of the cylinder, respectively, and a filter screen is fixedly connected to the inner side of the annular plate.

[0007] Furthermore, an inner threaded sleeve that is adapted to the circular hole wall at the corresponding threaded position of the roadside layer is fixedly connected, and a plurality of seepage channels are connected between the first water passage cavity and the second water passage cavity.

[0008] Furthermore, several reinforcing steel frames are equidistantly installed on the top of the inner wall of the water storage tank, and both ends of the reinforcing steel frames are fixedly connected to the side of the inner wall of the water storage tank.

[0009] Furthermore, a number of reinforcing struts are equidistantly installed at the bottom of the reinforcing steel frame, and the bottom ends of the reinforcing struts are fixedly connected to the bottom of the inner wall of the water storage tank.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] In the event of heavy rain, rainwater can permeate through the filter into the first water passage chamber, flow through the infiltration channel to the second water passage chamber, and then seep into the permeable concrete layer through the second infiltration hole. Finally, it enters the water storage tank through the first infiltration hole for collection. The water pipe can be connected to roadside greening equipment for plant irrigation or can be connected to groundwater, thus avoiding waste. This permeable concrete structure with rainwater collection function is reasonably designed. In the event of heavy rain, it can effectively drain rainwater and collect and utilize it. During the collection process, it can simultaneously prevent the inflow of debris, thus ensuring the cleanliness of the rainwater and avoiding water waste. Moreover, the overall concrete structure has high strength and long service life, and has good performance. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4 A permeable concrete structure with rainwater harvesting function includes, from bottom to top, a road base layer 1, a water storage tank 2, a permeable concrete layer 3, and a pavement layer 4. Two roadside layers 5 are also provided on top of the road base layer 1. The roadside layers 5 are in close contact with the water storage tank 2, the permeable concrete layer 3, and the pavement layer 4. Water pipes 6 are connected to both sides of the water storage tank 2. Electrically controlled valves are installed on the water pipes 6, which can be connected to roadside greening equipment for plant irrigation or channeled into groundwater to avoid waste. Several first infiltration holes 7 are arranged in a matrix on the top of the water storage tank 2, allowing water to seep from the permeable concrete... Rainwater seeping from the soil layer 3 can flow into the water storage tank 2 through the first infiltration hole 7. The roadside layer 5 has a first water passage cavity 8 and a second water passage cavity 9 respectively from top to bottom. The second water passage cavity 9 is connected to the permeable concrete layer 3 by several second infiltration holes 10. Rainwater entering the second water passage cavity 9 can enter the permeable concrete layer 3 through the second infiltration holes 10 for infiltration. Several filter elements 11 are installed at equal intervals on opposite sides of the two roadside layers 5 and corresponding to the positions of the first water passage cavity 8. The filter elements 11 can filter out large particles of debris mixed in the rainwater, thereby ensuring the cleanliness of the collected rainwater.

[0019] Specifically, the filter element 11 includes a cylinder 1101, the outer surface of the cylinder 1101 is provided with a threaded portion 1102, the left and right ends of the cylinder 1101 are respectively fixedly connected to a filter cylinder 1103 and an annular plate 1104, and the inner side of the annular plate 1104 is fixedly connected to a filter screen 1105.

[0020] Specifically, an inner threaded sleeve 12 is fixedly connected to the wall of the round hole corresponding to the threaded part 1102 of the roadside layer 5. The inner threaded sleeve 12 can be used in conjunction with the threaded part 1102 to install and remove the filter element 11. When a filter element 11 is damaged, it can be disassembled for repair or replacement in time. Several seepage channels 13 are connected between the first water passage chamber 8 and the second water passage chamber 9.

[0021] Specifically, several reinforcing steel frames 14 are installed at equal intervals on the top of the inner wall of the water storage tank 2. Both ends of the reinforcing steel frames 14 are fixedly connected to the side of the inner wall of the water storage tank 2. The reinforcing steel frames 14 can form an effective support for the top of the water storage tank 2, thereby improving the overall strength of the permeable concrete layer 3 and the road surface layer 4.

[0022] Specifically, several reinforcing struts 15 are installed at equal intervals at the bottom of the reinforcing steel frame 14. The bottom end of the reinforcing strut 15 is fixedly connected to the bottom of the inner wall of the water storage tank 2. Similarly, the reinforcing struts 15 can effectively support the reinforcing steel frame 14 and further improve the support strength.

[0023] This permeable concrete structure with rainwater harvesting function is reasonably designed. In the event of heavy rain, it can effectively drain rainwater and collect and utilize it. During the collection process, it can simultaneously prevent the inflow of debris, thereby ensuring the cleanliness of the rainwater and avoiding the waste of water resources. In addition, the overall concrete structure has high strength, long service life, and good performance.

[0024] Working principle: In case of heavy rain, rainwater can permeate through the filter element 11 into the first water passage chamber 8, and then flow through the infiltration channel 13 to the second water passage chamber 9. It then seeps into the permeable concrete layer 3 through the second infiltration hole 10, and finally enters the water storage tank 2 through the first infiltration hole 7 for collection. The water pipe 6 can be connected to the roadside greening equipment for plant irrigation, or it can be connected to the groundwater to avoid waste.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
