Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of highway drainage system, specifically relates to a highway side slope shoulder drainage system. BACKGROUND

[0002] At present, the highway road boundary surface drainage engineering is generally composed of a pavement drainage system and a roadbed drainage system. The pavement drainage system drains central median rainwater and pavement rainwater and sewage into the roadbed drainage system, and then the roadbed drainage system drains the water out of the highway road boundary and into the natural water system.

[0003] The pavement drainage system is composed of a central median drainage pipe, a blind ditch, an ultra-high drainage ditch, a pavement transverse slope (or ultra-high) and a shoulder water retaining belt. The roadbed drainage system is composed of a side ditch, a drainage ditch, a water intercepting ditch, a platform drainage ditch and a torrent chute. The pavement drainage system collects central median rainwater and pavement rainwater and sewage, and then drains the water into the side ditch and the drainage ditch. The water intercepting ditch, the platform drainage ditch and the torrent chute collect side slope rainwater and then drain the water into the side ditch and the drainage ditch.

[0004] The side ditch and the drainage ditch drain rainwater and sewage by gravity flow, that is, the bottom of the side ditch and the drainage ditch needs to be set as a longitudinal slope along a certain direction, and the rainwater and sewage flow along the longitudinal slope. The side ditch of the excavation section is mostly arranged in parallel with the soil shoulder, and the longitudinal slope of the bottom of the side ditch is basically consistent with the longitudinal slope of the pavement. The side ditch water finally flows into the drainage ditch of the embankment section. If no intervention is made, the elevation of the bottom of the drainage ditch is set to adapt to the original terrain, but the original terrain is mostly undulating, which causes the elevation of the bottom of the drainage ditch to also be undulating. Therefore, under normal circumstances, in order to prevent the drainage ditch from being waterlogged, the elevation of the bottom of the drainage ditch needs to be adjusted appropriately when the roadbed drainage is designed, so that the longitudinal slope of the bottom of the drainage ditch is set along a certain direction, and until the lowest point of the elevation of the bottom of the drainage ditch of the section is connected to the adjacent water system such as a natural water channel, a river or a pond, a complete drainage system is formed.

[0005] However, in engineering practice, the traditional roadbed and pavement drainage system mainly composed of side ditches and drainage ditches has many shortcomings:

[0006] (1) It is heavily dependent on the terrain and the natural water system on the ground. The side ditch and the drainage ditch use gravity flow, and the water flows along the longitudinal slope of the bottom. This makes the elevation of the bottom of the drainage ditch heavily affected by the terrain. Although the elevation of the bottom can be artificially adjusted to be lowered or raised to form a one-way longitudinal slope towards the water outlet for drainage, the longitudinal slope of the bottom cannot be adjusted indefinitely, and it should be greater than or equal to 0.3% in general and greater than or equal to 0.1% in difficult cases. Therefore, the design of the drainage ditch often cannot conform to the terrain and the topography, and more lateral water outlets, more line-outlet drainage ditches or more lateral drainage culverts need to be added to connect the roadbed drainage system to the natural water system on the ground and improve the drainage design.

[0007] (2) Occupies more land. The size of the drainage ditch is generally not less than 60cm*60cm, and cast-in-situ plain concrete or prefabrication is adopted, and the wall thickness is greater than or equal to 20cm, therefore, the land width occupied by the drainage ditch is greater than or equal to 100cm, and more land needs to be occupied especially when facilities such as water diversion ditches are added.

[0008] (3) Higher project cost. The size of the drainage ditch is generally not less than 60cm*60cm, and cast-in-situ plain concrete or prefabrication is adopted, and the plain concrete consumption per meter of the drainage ditch is greater than or equal to 0.44m 3 In addition, water diversion ditches, transverse drainage culverts and the like need to be added, and the engineering scale is large.

[0009] The above-mentioned traditional roadbed and pavement drainage system is seriously dependent on the terrain, occupies more land and has a higher cost, and the design difficulty is large. When the drainage design is performed, if the elevation of the ditch bottom of the side ditch and the drainage ditch is artificially adjusted, the longitudinal slope of the ditch bottom is generally small, the drainage efficiency is low, and it is not conducive to rapidly draining the rainwater and sewage on the pavement. Moreover, the addition of facilities such as water diversion ditches and culverts outside the line for auxiliary drainage has a large influence on the natural water system. In order to solve the above-mentioned problems, a road slope soil shoulder drainage system is provided. Content of the utility model
