Detailed ways

As shown in Figures 1-4, a municipal road drainage structure includes a curb stone 1. The curb stone 1 is arranged between the road surface 7 and the green belt 8. The curb stone 1 is provided with a water guide groove 2 in the middle. A first water inlet 3 is provided on the side facing the road surface 7, one end of the first water inlet 3 is connected to the water guide 2, and the other end is located above the road surface 7;

A drain pipe 5 is provided in the ground below the curb stone 1 , and a first water outlet 4 communicated with the drain pipe 5 is provided at the bottom of the water guide 2 .

In a preferred solution, the drainage pipe 5 adopts a tubular structure with one end open, and the open end of the drainage pipe 5 is the second water outlet 13, the second water outlet 13 is communicated with the sewer 6, and the second water outlet 13 is provided with a positioning The lug plate 15 is provided with a connecting rod 14 on the positioning lug plate 15 , and a mesh plate 16 is disposed on one end of the connecting rod 14 away from the second water outlet 13 .

In a preferred solution, the size of the mesh plate 16 is the same as the internal size of the drain pipe 5 .

In a preferred solution, the green belt 8 includes a base layer 11 at the bottom, a gravel layer 10 is arranged above the base layer 11, and a soil layer 9 is arranged above the gravel layer 10;

The base layer 11 is a plate-like structure composed of a first combination block 111 and a second combination block 112, wherein the first combination block 111 adopts a plate-shaped structure with a right-angled trapezoid cross-section, and the second combination block 112 adopts a rectangular cross-section. The plate-like structure of the second combination block 112 is arranged with the oblique waist of the right-angled trapezoid facing upward and the straight waist facing downward, the second combination block 112 is fixedly arranged on the upper bottom of the first combination block 111, and the second combination block There are also vertical water permeable holes 12 .

In a preferred solution, two second water inlets 501 are provided on the top surface of the drainage pipe 5 , and the two second water inlets 501 are respectively arranged in alignment with the first water outlet 4 and the permeable hole 12 .

The new drainage principle is as follows:

When it rains, the rainwater near the sewer 6 flows into the sewer 6 through the rain grate along the road, while the rainwater in the area between two adjacent sewers 6 passes through the first water inlet 3 and enters the guide in the curb 1. In the water tank 2, when it flows to the position close to the sewer 6, it passes through the first water outlet 4 under the water guide tank 2 and then enters the drain pipe 5 and finally discharges into the sewer 6, effectively avoiding the section of the road surface 7 where the sewer 6 is not provided. stagnant water inside;

The accumulated water in the green belt 8 passes through the gravel layer 10 and flows along the base layer 11 to the permeable hole 12 and falls into the drainage pipe 5 , so as to achieve the purpose of discharging the accumulated water in the green belt 8 .

When the drainage pipe 5 needs to be dredged and dredged, the rainwater grate is opened and the connecting rod 14 is manually pulled, so that the mesh plate 16 drives the silt garbage into the sewer 6 .

By adopting the above structure, the drainage of each area of the road surface is realized through the water guiding groove inside the curb stone, which avoids the generation of water accumulation on the road surface area between the two sewers; realizes the discharge from the greening to the accumulated water, and avoids the pollution caused by the green belt. Rainwater diffuses into the stratum, causing the subgrade of the stratum to become soft; after long-term drainage by the drainage pipe, the accumulated garbage and silt can be quickly discharged through the mesh plate, realizing the purpose of quickly clearing the drainage pipe between the green belt and the sewer.
