Description

Technical Field

[0001] The present application relates to the field of pavement drainage technology, and in particular to a drainage curbstone and a pavement drainage structure. Background Art

[0002] The pavement drainage structure is a structure that drains rainwater on the road surface into the municipal drainage network during rainfall. The combination of a rainwater well and a rain grate is a common pavement drainage structure. Usually, a rainwater well connected to the municipal drainage network is excavated on one side of the road, and the inner wall of the rainwater well is reinforced and waterproofed with cement. Then, a rain grate is installed above the rainwater well so that when it rains, rainwater can enter the rainwater well through the rain grate and eventually flow into the municipal drainage network. During rainfall, rainwater is prone to carry some road garbage and easily clog the rain grate, resulting in a reduction in the water flow of the rain grate or directly causing the rain grate to be blocked, affecting the drainage of the road surface, making it easy for a large amount of water to accumulate on the road surface. Utility Model Content

[0003] In order to solve the problem that the drainage efficiency of the road surface drainage structure is affected by the blockage of the rain grate on the road surface, the present application provides a drainage curbstone and a road surface drainage structure.

[0004] To achieve the above objectives, in a first aspect, the present application provides a drainage curbstone, which adopts the following technical solution:

[0005] A drainage curbstone comprises a curbstone body, wherein the curbstone body has a drainage chamber, wherein the drainage chamber has a chamber opening formed on the outer side of the curbstone body, and the chamber opening has a water inlet area located on the upper side of the road and a drainage area for connecting with a rainwater well under a rain grate.

[0006] By adopting the above technical solution, after the above drainage curbstone is installed on one side of the road, a portion of the cavity opening of the drainage curbstone is located above the road surface, and a portion is located below the road surface and connected to the rainwater well, so that when it rains, rainwater can enter the rainwater well through the drainage cavity of the drainage curbstone, thereby alleviating the rainwater drainage pressure on the road surface when the rain grate is blocked by leaves and other debris, which helps to improve the drainage efficiency of the road drainage structure.

[0007] Preferably, the curb body is provided with a drainage slope at the bottom of the drainage chamber, and the drainage slope is arranged to be inclined downward in a direction close to the opening of the chamber.

[0008] By adopting the above technical solution, rainwater is discharged into the rainwater well through the drainage slope after entering the drainage chamber. The drainage slope can guide the rainwater, thereby helping the rainwater to be discharged into the rainwater well more quickly.

[0009] Preferably, the acute angle formed by the drainage slope and the horizontal plane is 30° to 60°.

[0010] By adopting the above technical solution, the drainage slope has an ideal guiding effect on rainwater within the above inclination.

[0011] Preferably, the curb body is provided with a drainage plane at the bottom of the drainage chamber.

[0012] Preferably, the chamber opening is rectangular or semicircular.

[0013] Preferably, the depth of the drainage chamber is 50-100 mm.

[0014] By adopting the above technical solution, the depth of the drainage chamber affects the drainage capacity of the drainage curbstone. When the drainage chamber is within the depth range of 50 to 100 mm, it has a relatively ideal drainage capacity and can ensure that the curbstone body has a relatively ideal structural strength.

[0015] In a second aspect, the present application provides a road drainage structure, which adopts the following technical solution:

[0016] A road drainage structure includes a rainwater well opened on one side of the road, a rain grate installed above the rainwater well, and a drainage curbstone arranged at the edge of the road and located on one side of the rain grate. The rainwater well is provided with a drainage outlet connected to a municipal drainage network, and the drainage curbstone is the above-mentioned drainage curbstone.

[0017] By adopting the above technical solution, when it rains, rainwater can enter the rainwater well through the rain grate, and can also enter the rainwater well through the drainage chamber of the drainage curb, thereby improving the drainage efficiency of the road drainage structure and avoiding the problem of large amount of water on the road when the rain grate is blocked by debris such as fallen leaves.

[0018] Preferably, the rainwater well is further provided with a grille basket located obliquely below the drainage curbstone and used to receive rainwater discharged from the drainage curbstone into the rainwater well, and the drain outlet is located below the grille basket.

[0019] By adopting the above technical solution, after rainwater enters the rainwater well through the drainage chamber of the drainage curbstone, it will flow directly into the grille basket. The fallen leaves and other debris originally in the rainwater will be filtered in the grille, thereby reducing the fallen leaves and other debris entering the municipal drainage network through the drain outlet.

[0020] Preferably, the rainwater well is provided with a support rail which is horizontally perpendicular to the drainage curbstone and is used to support the grille basket, and the grille basket is slidably mounted on the support rail along the length direction of the support rail.

[0021] By adopting the above technical solution, the grille basket can slide horizontally along the supporting slide rail. When cleaning is required, the grille basket can be slid from the side close to the drainage curb to the side away from the drainage curb, thereby facilitating the cleaning of debris in the grille basket.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] A drainage curbstone is provided with a drainage chamber so that rainwater can flow into a rainwater well through the drainage chamber, thereby alleviating the rainwater drainage pressure on the road surface when the rain grate is blocked by leaves and other debris, and helping to improve the drainage efficiency of the road surface drainage structure;

[0024] The drainage curbstone is provided with a drainage slope on the bottom surface of the drainage chamber, so as to guide the rainwater entering the drainage chamber, thereby increasing the speed of the rainwater in the drainage chamber, and helping to improve the drainage efficiency of the rainwater discharged into the rainwater well through the drainage curbstone;

[0025] A road drainage structure is provided. By arranging the drainage curbstone on one side of a rain grate, rainwater can enter the rainwater well through the rain grate when it rains, and can also enter the rainwater well through the drainage cavity of the drainage curbstone, thereby improving the drainage efficiency of the road drainage structure.
