Problems solved by technology

The rainwater outlets of point-of-use drainage grates have the following defects and deficiencies: 1. Since the rainwater outlets are usually located on the side of the street and road close to the curb, rainwater can only pass through the grate holes on the side away from the curb. The grate holes on one side are used to collect rainwater, but the grate holes on the side near the curb do not pass through the rainwater. It can be seen that the grate that is too wide not only wastes the raw materials needed to make the grate, but also affects the drainage effect
2. Increasing the width of the grate will inevitably reduce the compressive strength of the grate. Heavy and large buses must drive close to the curb and repeatedly enter and exit the station, which will inevitably exert a huge impact on the grate covering the rainwater outlet. Pressure can easily cause damage to the grate, affecting driving safety and smooth roads. If you want to increase the compressive strength of the grate, you can only increase the thickness, which will cause waste of raw materials
3. Due to the relatively short grate of the point drainage rainwater outlet, the leaves, branches and other sundries on the road will easily block all the grate holes after the rainwater enters the area where the grate is located, resulting in poor drainage

Embodiment 1

[0015] Such as figure 1 The linear narrow gully grate shown has a cuboid frame structure, and the inside of the cuboid frame has grid-shaped grate holes 1. The width of the grate is 170 mm, the length is 680 mm, and the ratio of width to length is 0.25. The upper surface of the grate is provided with a raised "back" pattern 2.

[0016] The water collection performance test was carried out on the aforementioned grate (narrow grate) and the 680×380 mm grate (wide grate). The test results are as follows:

[0017] Grating specification(mm)

[0018] In the aforementioned test experiments, the length of the grates was 680 mm. Since the water flow often can only pass through the grate holes on the side away from the curb, as the width of the grate increases, the water-passing width increases, but it cannot be compared with the grate. The width of the grate increases in the same proportion, and the water passing area does not expand significantly; at the same time, because ...

Embodiment 2

[0020] Such as figure 2 The linear narrow gully grate shown has a cuboid frame structure, and the inside of the cuboid frame has grid-shaped grate holes 1. The width of the grate is 300 mm, the length is 800 mm, and the ratio of width to length is 0.375. The upper surface of the grate is provided with a raised "back" pattern 2.

[0021] The water collection performance test was carried out on the aforementioned grate (narrow grate) and the 600×400 mm grate (wide grate). The test results are as follows:

[0022] Grating specification(mm)

[0023] In the aforementioned test experiments, the surface area of ​​the grates is 0.24 square meters. Since the water flow can only pass through the grate holes on the side away from the curb, the water flow can flow through the entire surface area of ​​the narrow grate, but not the entire surface area of ​​the wide grate. . Although the water passing width of the wide grate is greater than that of the narrow grate, because the ...

Embodiment 3

[0025] Such as image 3 The linear narrow gully grate shown has a cuboid frame structure, and the inside of the cuboid frame has grid-like grate holes 1, the width of which is 272 mm, the length is 680 mm, and the ratio of width to length is 0.4, the grate The upper surface is provided with a raised "back" pattern 2.

[0026] The water collection performance test was carried out on the aforementioned grate (narrow grate) and the 680×430 mm grate (wide grate). The test results are as follows:

[0027] Grating specification(mm)

[0028] In the above-mentioned test experiments, the length of the grates was 680 mm. Since the water flow can only pass through the grate holes on the side away from the curb, as the width of the grate increases, the water passing area does not increase significantly; The depth of the water flow is shallow, resulting in a smaller flow of the wide grate. It can be seen from the above experiments that the linear narrow grate can improve the ef...

Abstract

The invention discloses a linear narrow grate gutter inlet grating, the ratio of width and length thereof is 0.25-0.4. The size of gutter inlet grating is optimized, the width of the grating is reduced appropriately and the length of the grating is increased, thus forming the linear narrow grate gutter inlet grating. By utilizing the grating to collect rainwater, rainwater almost can flow the whole grate holes, thus improving water collecting efficiency and speed; and meanwhile the compression strength of the grating is improved, and raw material is saved.

Description

technical field [0001] The invention relates to a water supply and drainage facility, in particular to a road drainage facility. Background technique [0002] At present, the size of ordinary gully grates used on streets and roads is 680×380 mm (680 mm in length and 380 mm in width), and there are also gully grates with dimensions of 680×430 mm and 600×400 mm. ; Because the ratio of the width and length of these grates is greater than 0.5, and the shape of the upper and lower surfaces is close to a square, they are usually called point drainage grates. The rainwater outlets of point-of-use drainage grates have the following defects and deficiencies: 1. Since the rainwater outlets are usually located on the side of the street and road close to the curb, rainwater can only pass through the grate holes on the side away from the curb. The grate holes on one side serve to collect rainwater, but the grate holes on the side near the curb do not pass through the rainwater. It can b...
