Road double-layer drainage structure

Abstract

The utility model provides a road double-layer drainage structure. The road drainage structure solves the technical problems that a common road drainage structure usually adopts a single-layer ditch type, the use effect in a southern rainy area is not good, and the drainage capacity can be greatly influenced once a ditch is blocked. The road double-layer drainage structure comprises a shell body, a water inlet is formed in the top of the shell body, a U-shaped guide groove piece is installed below the water inlet to serve as a first drainage area, U-shaped grooves are formed in the two sides of the U-shaped guide groove piece to serve as second drainage areas, extending parts are arranged on the two sides of the U-shaped guide groove piece, and the upper portions of the extending parts are connected with the shell body through a plurality of first supporting columns. The bottom of the U-shaped groove is connected below the extending part through a plurality of second supporting columns. On the basis of an original single-layer drainage structure, a layer of drainage structure is additionally arranged, the larger drainage requirement can be met, and meanwhile the influence of ditch blockage on the drainage capacity is reduced.

Description

Technical Field

[0001] The utility model belongs to the technical field of construction and relates to a double-layer drainage structure for a road. Background Art

[0002] As an important traffic channel, the drainage capacity of the road is particularly important in the rainy season, which is related to whether the road can be passed. The general road drainage structure usually adopts a single-layer ditch type, which is not very effective in the rainy areas in the south, and once the ditch is blocked, it will greatly affect the drainage capacity. Therefore, it is necessary to design a double-layer road drainage structure. Summary of the invention

[0003] The utility model aims to solve the above problems in the prior art and proposes a double-layer drainage structure for roads.

[0004] The purpose of the utility model can be achieved through the following technical solutions: a double-layer road drainage structure, including an outer shell body, characterized in that a water inlet is arranged on the top of the outer shell body, a U-shaped guide groove member is installed below the water inlet as a first drainage area, U-shaped grooves are arranged on both sides of the U-shaped guide groove member as a second drainage area, and extensions are arranged on both sides of the U-shaped guide groove member, the upper part of the extension is connected to the outer shell body through a plurality of support columns 1, and the lower part of the extension is connected to the bottom of the U-shaped groove through a plurality of support columns 2.

[0005] The working principle of the utility model is as follows: after the drainage structure is installed at a designated position, water enters the first drainage area through the water inlet and is discharged through the U-shaped guide groove part, thereby meeting general drainage needs; when the amount of water is large, the water will overflow the U-shaped guide groove part, and the overflowed water will flow into the second drainage area through the extensions on both sides of the U-shaped guide groove part and be discharged through the U-shaped groove.

[0006] The support column 1 and the support column 2 are alternately arranged at upper and lower positions.

[0007] The above structure is adopted to increase the overall stability and supporting capacity.

[0008] A filter screen is installed at the water inlet.

[0009] The above structure is adopted to reduce the amount of debris entering the drainage structure.

[0010] The size of the U-shaped guide groove member is larger than the size of the water inlet, and the gap between the extension portion and the top of the shell body is set to 20-30 mm.

[0011] The above structure can prevent large objects from falling into the second drainage area without affecting drainage.

[0012] The bottom of the U-shaped guide groove is fixedly connected to the shell body.

[0013] The above structure is adopted to increase the overall stability.

[0014] Compared with the prior art, the double-layer drainage structure of the road has the following advantages: on the basis of the original single-layer drainage structure, the utility model adds a layer of drainage structure, which can meet greater drainage needs while reducing the impact of ditch blockage on drainage capacity.

[0019] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0020] like Figure 1-3 As shown, the double-layer drainage structure of the road includes an outer shell body 1, a water inlet is arranged on the top of the outer shell body 1, a U-shaped guide groove member 2 is installed below the water inlet as the first drainage area, U-shaped grooves 3 are arranged on both sides of the U-shaped guide groove member 2 as the second drainage area, and extension parts are arranged on both sides of the U-shaped guide groove member 2, the upper part of the extension part is connected to the outer shell body 1 through a plurality of support columns 1 4, and the lower part of the extension part is connected to the bottom of the U-shaped groove 3 through a plurality of support columns 2 5.

[0021] In the utility model, the shell body 1 is made of stone, and a metal layer is arranged inside the shell body 1.

[0022] In the utility model, the U-shaped guide groove member 2, the support column 1 4 and the support column 2 5 are made of the same material as the inner metal layer of the shell body 1 .

[0023] The metal layer structure is adopted to ensure high strength and corrosion resistance.

[0024] The support column 1 4 and the support column 2 5 are arranged alternately in upper and lower positions.
