Description

Technical Field

[0001] The utility model relates to the technical field of road drainage, in particular to a road drainage structure that can avoid being blocked by sediment. Background Art

[0002] Conventional municipal roads drain water through rainwater grates and drains, but when it rains, rainwater will carry a lot of sediment into the drain through the rainwater grates, slowly causing a lot of sediment to accumulate in the drain, reducing the drainage effect. Utility Model Content

[0003] The utility model provides a road drainage structure for solving the above technical deficiencies and preventing silt blockage, which can reduce silt accumulation in the drainage channel.

[0004] The utility model discloses a road drainage structure for avoiding clogging by mud and sand, comprising a drainage channel, wherein a rainwater grate is arranged on the upper side of the drainage channel, the bottom of the drainage channel is arranged in a V-shaped structure, guide plates inclined downward are symmetrically arranged on the upper parts of the side walls on both sides of the drainage channel, a gap is left between the ends of the two guide plates that are close to each other, and the lower part of the gap corresponds to the lowest point of the V-shaped structure at the bottom of the drainage channel.

[0005] The principle of the above scheme is that rainwater carrying silt enters the drain through the rainwater grate, is gathered together through the guidance of the guide plate, and flows down from the gap between the two guide plates. Since the bottom of the drain is set to a V-shaped structure, the silt in the rainwater will rely on its own gravity to gather to the lowest point of the V-shaped structure during the process of rainwater carrying silt being discharged at the bottom of the drain. However, since the lowest point of the V-shaped structure at the bottom of the drain corresponds to the gap directly below, the silt gathered at the lowest point of the V-shaped structure will be impacted by the continuously falling rainwater again and mixed evenly with it, so that the rainwater can always carry the silt and flow away in the drain, reducing the accumulation of silt in the drain.

[0006] Preferably, the width of the gap is 10 cm.

[0007] In order to facilitate the installation of the guide plate, a bent portion is provided upward at the end of the guide plate close to the side wall of the drain channel, a through hole is provided on the bent portion, and mounting holes are provided at positions corresponding to the through holes on the side wall of the drain channel. The bent portion and the side wall of the drain channel are fixed through the through holes, the mounting holes and the expansion bolts.

[0008] In order to facilitate the collection of larger impurities such as leaves, a filter frame is arranged directly below the gap between the two guide plates. The width of the filter frame is smaller than the width of the gap. The filter frame is connected to the rainwater grate through a connecting rod. The rainwater flowing from the gap is first filtered through the filter frame to intercept larger impurities such as leaves. When there are many impurities in the filter frame, lift the rainwater grate upwards and take out the filter frame for cleaning.

[0009] The road drainage structure obtained by the utility model avoids silt blockage, and its beneficial effect is that by setting the bottom of the drainage channel into a V-shaped structure, the silt in the rainwater is gathered to the lowest point of the V-shaped structure, and through the guiding effect of the guide plate, the silt gathered at the lowest point of the V-shaped structure will be impacted by the continuously falling rainwater again and mixed evenly with it, so that the rainwater can always carry the silt to flow away in the drainage channel, thereby reducing the accumulation of silt in the drainage channel.

[0010] Figure 1 This is a schematic diagram of the structure of Example 1 of the utility model. DETAILED DESCRIPTION

[0011] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0012] Embodiment 1:

[0013] like Figure 1 As shown, the utility model discloses a road drainage structure for avoiding silt blockage, comprising a drainage channel 1, a rainwater grate 4 is arranged on the upper side of the drainage channel 1, the bottom of the drainage channel 1 is arranged in a V-shaped structure 2, and guide plates 3 inclined downward are symmetrically arranged on the upper parts of the side walls on both sides of the drainage channel 1, and a gap is left between the ends of the two guide plates 3 that are close to each other, the width of the gap is 10 cm, and the lowest point of the V-shaped structure 2 at the bottom of the drainage channel 1 corresponds to the bottom of the drainage channel 1.

[0014] The principle of the above scheme is that rainwater carrying silt enters the drain 1 through the rainwater grate 4, is gathered together through the guidance of the guide plate 3, and flows down from the gap between the two guide plates 3. Since the bottom of the drain 1 is set as a V-shaped structure 2, the silt in the rainwater will rely on its own gravity to gather to the lowest point of the V-shaped structure 2 during the process of rainwater carrying silt being discharged from the bottom of the drain 1. However, since the lowest point of the V-shaped structure 2 at the bottom of the drain 1 corresponds to the gap directly below, the silt gathered at the lowest point of the V-shaped structure 2 will be impacted by the continuously falling rainwater again and mixed evenly with it, so that the rainwater can always carry the silt and flow away in the drain 1, reducing the accumulation of silt in the drain 1.

[0015] In order to facilitate the installation of the guide plate 3, a bent portion is provided upward at the end of the guide plate 3 close to the side wall of the drain channel 1, a through hole is provided on the bent portion, and a mounting hole is provided at a position corresponding to the through hole on the side wall of the drain channel 1. The bent portion and the side wall of the drain channel 1 are fixed by means of the through hole, the mounting hole and the expansion bolt 7.

[0016] In order to facilitate the collection of larger impurities such as leaves, a filter frame 6 is arranged directly below the gap between the two guide plates 3. The width of the filter frame 6 is smaller than the width of the gap. The filter frame 6 is connected to the rainwater grate 4 through a connecting rod 5. The rainwater flowing down from the gap is first filtered through the filter frame 6 to intercept larger impurities such as leaves. When there are many impurities in the filter frame 6, the rainwater grate 4 is lifted up and the filter frame 6 can be taken out for cleaning.
