Description

Technical Field

[0001] This utility model relates to the field of permeable pavement technology, specifically to an ecological permeable concrete pavement. Background Technology

[0002] Permeable pavement, also known as ecological permeable pavement, permeable concrete, or no-fines concrete, is made by uniformly mixing aggregates, binders, additives, cement, and water, and then spreading it into a road surface. It is compatible with the natural environment, reduces the burden on the earth and the ecological environment, and realizes the recyclable use of non-renewable resources. It has good functionality and can create a mild, comfortable, and convenient living environment for human beings.

[0003] In response, Chinese patent application number CN202220538553.2 discloses a permeable pavement drainage structure, which includes a pavement body and a drainage ditch disposed on one side of the pavement body. The pavement body includes, from bottom to top, a subgrade layer, a cement-stabilized layer, a permeable concrete layer, and a permeable pavement layer. The permeable concrete layer contains several drainage pipes, each with several water inlets evenly distributed on it. The end of each drainage pipe near the drainage ditch is inclined downwards and extends into the drainage ditch. Several guide pipes are provided along the length of each drainage pipe, all extending vertically with their tips extending into the permeable pavement layer. A sealing plate and a control mechanism for controlling the opening and closing of the sealing plate are provided at the opening of the drainage pipe at the end located in the drainage ditch. This application enhances the drainage capacity of the permeable pavement.

[0004] The floor can guide rainwater into the drainage ditch by installing drainage pipes. However, because there are inlets on the drainage pipes, rainwater inside the drainage pipes will also flow to the outside through the inlets during normal use, resulting in waste of rainwater.

[0005] Therefore, in order to solve the above problems, an ecological permeable concrete pavement is proposed. Utility Model Content

[0006] The purpose of this utility model is to provide an ecological permeable concrete pavement to solve the problem mentioned in the background art where the existing pavement can guide rainwater into the drainage ditch by setting up drainage pipes, but because the drainage pipes have inlets, the water in the drainage pipes will also flow to the outside through the inlets during normal use, causing a waste of water resources.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an ecological permeable concrete pavement, comprising: a subgrade layer, a permeable concrete layer laid on the top surface of the subgrade layer, a permeable pavement layer laid on the top surface of the permeable concrete layer, a drainage ditch provided on the left side of the subgrade layer, and a manhole cover laid on the top surface of the drainage ditch.

[0008] The permeable concrete layer is equipped with a drainage structure, which includes a drainage pipe laid inside the permeable concrete layer. The drainage pipe has a movable cavity at its bottom end and a drainage outlet on its bottom surface. A cylindrical groove is formed at the left end of the movable cavity. A connecting cylinder is integrally formed at the bottom of the left end of the drainage pipe. A movable sleeve is fitted on the outer side of the bottom end of the connecting cylinder. A float ball is fixedly connected to the bottom end of the movable sleeve. A ball bearing assembly is installed inside the connecting cylinder. A water baffle is slidably installed inside the movable cavity. A through hole is formed on the surface of the water baffle. A top column is integrally formed at the left end of the water baffle. A spring is fixedly connected to the right end of the water baffle.

[0009] Preferably, the drain pipe is installed at an angle, and the left end of the drain pipe is connected to the inside of the drainage ditch.

[0010] Preferably, the top surface of the drain pipe is equipped with a guide plate for collecting rainwater, and the drain outlet is offset from the through hole.

[0011] Preferably, the top surface of the movable sleeve contacts the bottom end of the ball assembly, and the left end of the top post contacts the upper end of the ball assembly.

[0012] Preferably, the top post is located inside the cylindrical groove.

[0013] Preferably, one end of the spring is fixedly connected to the inner wall of the movable cavity.

[0014] Compared with the prior art, the beneficial effects of this utility model are: by setting a movable baffle, the position between the through hole and the drain outlet can be adjusted when moving, so as to improve the functionality of the drain pipe, ensure the drainage pipe's guiding effect on rainwater, and reduce rainwater waste.

[0015] This invention features a drainage structure that allows collected rainwater to flow downwards into a drain pipe. The rainwater then flows into the inner side of the drainage ditch. At this point, the baffle plate, under the action of a spring, is positioned at the left end of the movable cavity, and the drain outlet and through hole are offset. Therefore, all the rainwater in the drain pipe can flow into the drainage ditch without leakage, ensuring efficient rainwater collection. When there is a large amount of rainwater flowing in the drainage ditch, the rainwater provides buoyancy to the float, causing the movable sleeve to move upwards on the outside of the connecting cylinder. The movable sleeve pushes the ball assembly, which moves within the connecting cylinder, pushing the top column in the cylindrical groove. The through hole, under the action of the top column, moves to the right within the movable cavity, aligning the drain outlet and through hole. The interiors of the drain pipe, drain outlet, and through hole are now connected. At this point, the water flowing in the drain pipe can flow downwards through the drain outlet and through hole, reducing the amount of water injected into the drainage ditch and preventing overflow due to excessive water, which could cause road flooding and affect pedestrian experience.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0022] Please see Figures 1-4 One embodiment provided by this utility model:

[0023] The subgrade layer 1, permeable concrete layer 11, permeable pavement layer 12, drainage ditch 13, manhole cover 14 and drainage pipe 21 used in this application are products that can be directly purchased on the market. Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be described in detail here.

[0024] An ecological permeable concrete pavement includes: a soil layer 1, a permeable concrete layer 11 laid on the top surface of the soil layer 1, a permeable pavement layer 12 laid on the top surface of the permeable concrete layer 11, a drainage ditch 13 provided on the left side of the soil layer 1, and a manhole cover 14 laid on the top surface of the drainage ditch 13.

[0025] A drainage structure 2 is installed inside the permeable concrete layer 11. The drainage structure 2 includes a drainage pipe 21, which is laid inside the permeable concrete layer 11. A movable cavity 22 is opened inside the bottom end of the drainage pipe 21, and a drainage outlet 23 is opened on the bottom surface of the drainage pipe 21. A cylindrical groove 24 is opened at the left end of the movable cavity 22. A connecting cylinder 25 is integrally formed at the bottom of the left end of the drainage pipe 21. A movable sleeve 26 is fitted on the outside of the bottom end of the connecting cylinder 25, and a float ball 27 is fixedly connected to the bottom end of the movable sleeve 26. A ball bearing assembly 28 is installed on the inner side of the connecting cylinder 25, and a baffle plate 29 is slidably installed on the inner side of the movable cavity 22. A through hole 210 is opened on the surface of the baffle plate 29. A top post 211 is integrally formed on the left end of the baffle plate 29, and a spring 212 is fixedly connected to the right end of the baffle plate 29. The baffle plate 29 is movable. When moving, the position between the through hole 210 and the drain outlet 23 can be adjusted to improve the functionality of the drain pipe 21, ensure the guiding effect of the drain pipe 21 on rainwater, and reduce the waste of rainwater.

[0026] Furthermore, the drain pipe 21 is installed at an angle, and the left end of the drain pipe 21 is connected to the inside of the drainage ditch 13. Rainwater can flow in one direction in the drain pipe 21 so as to transport the rainwater into the drainage ditch 13.

[0027] Furthermore, a guide plate for collecting rainwater is installed on the top surface of the drain pipe 21, and the drain outlet 23 is offset from the through hole 210. During normal use, rainwater in the drain pipe 21 will not leak out through the drain outlet 23 and the through hole 210.

[0028] Furthermore, the top surface of the movable sleeve 26 contacts the bottom end of the ball assembly 28, and the left end of the top post 211 contacts the upper end of the ball assembly 28. The movement of the movable sleeve 26 can push the ball assembly 28 upward, so as to push the top post 211 through the ball assembly 28, causing the baffle plate 29 to move within the movable cavity 22.

[0029] Furthermore, the top post 211 is located inside the cylindrical groove 24, and the ball assembly 28 can move within the cylindrical groove 24 to move in a regular manner in order to push the top post 211.

[0030] Furthermore, one end of the spring 212 is fixedly connected to the inner wall of the movable cavity 22. The spring 212 provides power to the baffle plate 29 located at the left end of the movable cavity 22, so that the drain outlet 23 is offset from the through hole 210, ensuring the experience of daily use.

[0031] Working principle: When in use, the collected rainwater can enter the drain pipe 21 downwards. The rainwater flows into the inside of the drain ditch 13 along the drain pipe 21. At this time, the baffle plate 29 is located at the left end of the movable cavity 22 under the action of the spring 212, and the drain outlet 23 is offset from the through hole 210. Therefore, all the rainwater in the drain pipe 21 can flow into the drain ditch 13 without leakage, which can ensure the rainwater collection efficiency.

[0032] When there is a lot of rainwater flowing in the drainage ditch 13, the rainwater will give the float 27 buoyancy, causing the movable sleeve 26 to move upward outside the connecting cylinder 25. The movable sleeve 26 will push the ball assembly 28, which will move inside the connecting cylinder 25. This will push the top column 211 in the cylindrical groove 24. Under the action of the top column 211, the through hole 210 will move to the right in the movable cavity 22, so that the drain outlet 23 and the through hole 210 are aligned. The interiors of the drain pipe 21, the drain outlet 23 and the through hole 210 are connected. At this time, the water flowing in the drain pipe 21 can flow downward through the drain outlet 23 and the through hole 210 to reduce the amount of water injected into the drainage ditch 13 and prevent the drainage ditch 13 from overflowing due to excessive water, which would cause water accumulation on the road and affect the experience of pedestrians.

[0033] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
