The maintenance of the highway is more and more emphasized, the early damage water of the highway is the first 'sourcer', the drainage design relates to the service life and the use cost of the highway, and in order to prevent the water accumulation in the center of the highway surface in rain, the highway is generally set into a structure with a high middle and two low sides, so that the water in the center of the highway flows to the two sides of the highway, and finally the water accumulation on the highway surface is drained away through the drainage structures on the side slopes on the two sides of the highway.
At present, the drainage modes of the side slopes on two sides of the road surface of the expressway comprise two types, namely centralized drainage and distributed drainage:
(1) the distributed drainage is that no water retaining facility is arranged outside the highway, and rainwater naturally flows to the side slope after falling to the road surface and flows to the side ditch through the side slope to be drained away; the distributed drainage has the advantages of rapid drainage, no water accumulation on the road surface, contribution to driving safety and small damage of rainwater to the road surface; however, the mode is easy to cause secondary scouring to the surface of the side slope, and particularly the subgrade is seriously damaged by silt and expanded land areas;
(2) the centralized drainage is that the outer side of the highway is provided with a water blocking belt or a curb, the water blocking belt is provided with dustpan openings at intervals, the lower parts of the dustpan openings are connected with a rapid trough, and the rapid trough is connected with a side ditch. After the rainwater falls to the road surface, the rainwater is concentrated along the water blocking belt at the dustpan opening and then flows to the side ditch through the rapid trough to be discharged; the centralized drainage has the advantages of avoiding scouring of the surface of the side slope and being beneficial to protecting the roadbed; however, due to the fact that the highway pavement is not flat or the longitudinal slope changes, the accumulated water on the pavement between the water blocking belt and the two dustpan openings is prone to being drained and difficult to drain.
In the prior art, reference is made to a Chinese patent document with an authorization publication number of CN202898940U, which discloses a multifunctional dense-hole type highway side slope drainage structure used on two sides of a highway, and the highway side slope drainage structure comprises water blocking belts arranged on two sides of a road, wherein a drainage pipe buried in a side slope is arranged on each water blocking belt, the upper end of each drainage pipe penetrates through each water blocking belt, the lower end of each drainage pipe inclines downwards and is connected with a side ditch, a valve is arranged at the lower end of each drainage pipe, and a water seepage hole is arranged on the side wall of each drainage; the utility model discloses have the advantage of centralized drainage and distributed drainage concurrently, the shortcoming of two kinds of current drainage methods has been overcome, guarantee promptly that the ability of falling water can fully drain away, can not ponding on making road pavement, can not erode the side slope again, highway has been protected, highway's life has been prolonged, can irrigate the greening plant on the side slope through the cooperation in valve and infiltration hole again, the very big potential safety hazard of watering formula watering existence has been avoided, the traffic accident that will use a large amount of watering cars to water to the side slope plant when also having avoided dry season.
The multifunctional dense-hole highway side slope drainage structure permeates water in the water pipe into the side slope through the water seepage holes, so that the plant roots on the side slope are irrigated. However, when the rainfall is less, a small amount of rainwater can be rapidly drained by the drain pipe when entering the drain pipe, so that the water in the drain pipe does not permeate into the side slope and flows into the drain ditch to be drained away.
