Detailed Description

As shown in fig. 1-4, a road drainage structure of the present invention specifically comprises: the road surface 10 is provided with a groove 12, and the bottom of the groove 12 is communicated with a sewer pipe 11. The groove 12 is provided with a hard shoulder 20, and the top of the hard shoulder 20 is provided with a blind groove 23 extending downwards. The inside of the hard shoulder 20 is also provided with a water inlet pipe 21 and a water outlet pipe 22. One end of the water inlet pipe 21 is communicated with the blind groove 23, and the other end is communicated with the side surface of the isolation pier 20. One end of the water outlet pipe 22 is communicated with the blind groove 23, and the other end is communicated with the bottom surface of the isolation pier 20. The end of the water outlet pipe 22 at the bottom of the isolation pier 20 is matched with the sewer pipe 11, and the end of the water inlet pipe 21 at the side of the isolation pier 20 is as high as the road surface 10. A detachable garbage collector 30 is also arranged in the blind groove 23.

The garbage collector 30 includes a head 31 and a net body connected below the head 31. The mesh number of the water inlet side 33 of the net body close to the water inlet pipe 21 is smaller than that of the water outlet side 34 far away from the water inlet pipe 21, and the bottom of the net body is closed. The upper end of the blind groove 23 is provided with a concave platform for supporting the head 31, and the net body extends downwards to the bottom of the blind groove 23.

The bottom of the net body is provided with a balancing weight. The balancing weight can be a metal block or a stone block.

The head 31 is provided with an inwardly recessed groove 32. The isolation pier 20 and the garbage collector 30 can be more attractive integrally after being matched, and maintenance personnel can conveniently and quickly pull out the garbage collector 30.

The mesh number of the water inlet side 33 of the net body is 1/3 of the mesh number of the water outlet side 34. For example, the outlet side 34 has 24 meshes and the inlet side 33 has 8 meshes. The garbage collector is mainly used for blocking/collecting common pavement garbage such as paper towels, leaves and the like.

A highway drainage structures theory of operation as follows: when raining and the like occur, accumulated water is generated on the road surface, and the accumulated water flows into the water inlet pipe 21, is screened by the net body and then flows into the sewer pipe 11 through the water outlet pipe 22, so that effective drainage is realized. After small garbage such as leaves, cigarette ends and the like enters the water inlet pipe 21 along with the water flow, the small garbage can penetrate through the water inlet side 33 and is blocked by the water outlet side 34, so that the sewer pipe 11 is prevented from being blocked. When regular maintenance is required, maintenance personnel can complete the maintenance operation by lifting the whole garbage collector 30 through the groove 32 and then putting a new garbage collector 30 into the blind groove 23 again, which is very quick.

It is to be noted in particular that although the water inlet pipe 21 is provided with an opening only on one of the sides of the hard shoulder 20, it does not represent that water can only be removed from one side of the hard shoulder 20. It is clear to the road construction technicians that no watertight connection is made between each of the piers 20, so that water will automatically pass through the gaps between the piers 20 and flow freely on both sides of the piers 20. Therefore, the conditions of rain and the like can be ensured, and the water can be drained effectively.

Various other modifications and changes may be made by those skilled in the art based on the above-described technical solutions and concepts, and all such modifications and changes are intended to fall within the scope of the claims.
