Description

Technical Field

[0001] This utility model relates to the field of road engineering drainage technology, and in particular to a road drainage structure. Background Technology

[0002] Road drainage systems are one of the core supporting facilities in road engineering. Their drainage efficiency and stability directly affect the service life of roads, traffic safety, and the driving experience in rainy weather. However, current mainstream road drainage structures mostly rely on linear drainage ditches along the road surface. These ditches have a single drainage path and lack a tiered drainage design. In extreme weather conditions such as short-duration heavy rainfall, surface runoff quickly accumulates, easily causing drainage ditch blockages and a significant decrease in drainage efficiency. This can lead to problems such as road surface flooding and urban waterlogging. Furthermore, existing structures do not adequately address infiltration within the road structural layers. Most permeable pavements rely solely on the permeable layer's own pores for infiltration, lacking dedicated infiltration collection and drainage components. This results in infiltrated water accumulating between the subgrade and the permeable layer, easily eroding the base structure and reducing the subgrade's bearing capacity. Therefore, we propose a new road drainage structure. Utility Model Content

[0016] In this embodiment, C30 concrete is first mixed in advance, then evenly laid to form the base layer 11 and cured. A placement chamber is reserved during the pouring of the base layer 11, and the pressure balance pipe 5 is embedded inside the chamber. The space between the pipe and the placement chamber is filled and fixed with polyurethane foam. After the base layer 11 is cured, a cement-based penetrating crystalline interface agent is evenly applied to the top surface of the base layer 11. After the interface agent is surface dry, the geomembrane 12 is laid, with the laying direction consistent with the road length direction. The overlapping edges of adjacent membrane sheets are hot-melt welded, and then pressurized with air pressure. According to the method of inspection, the edge of the geomembrane 12 is fixed to the side of the base layer 11 with expansion bolts. Then, a porous ceramsite concrete permeable layer 13 is laid on the top surface of the geomembrane 12. The permeable layer 13 is constructed in two layers. After each layer is laid, it is lightly vibrated with a plate vibrator to avoid breaking the ceramsite. After compacting the voids, it is cured.

A set of adjustable drainage valves 234 located below connects the chamber 231 to the main drainage pipe network 3. Then, the filter screen 2 is installed. The inner wall of the corresponding drainage trough 21 is fixedly assembled by welding. At this time, the liquid level sensor 233 is fixedly assembled inside the silo 231, and the flow sensor is installed at the input end of the adjustable drainage valve 234. It is connected by a flange, with the sensor probe facing the direction of water flow. The controller 6 is fixed in the concrete distribution box on the side of the base layer 11. Then, the controller 6 is connected to the controller power supply, the liquid level sensor 233 is calibrated, and the water level warning value is set. After debugging, the cable joint is wrapped with waterproof tape, and the distribution box is filled with sealant for moisture prevention. Finally, the road surface is inspected and accepted to complete the construction of this drainage structure.
