As a preferred technical scheme of the utility model, the drainage guide pipe is made of concrete, the height of the drainage guide pipe is the same as that of the isolation layer, a large amount of accumulated water on the road surface can be directly discharged into the drainage channel from the drainage guide pipe, and the road is prevented from being soaked by the accumulated water.

As a preferred technical scheme of the utility model, the isolation layer is made of non-woven filament geotextile, and is repeatedly laid in multiple layers, so that rainwater permeating from the roadbed layer is filtered, and the roadbed layer is isolated from a lower side soil layer, thereby ensuring the stability of the whole structure and increasing the bearing capacity.

As a preferred technical scheme of the utility model, the isolation guide plate is provided with the drainage groove, the drainage groove opening is connected with the drainage groove, and water permeating from the isolation layer flows into the drainage groove through the drainage groove, so that the rainwater is prevented from further descending, and the immersion of a basement soil layer is reduced.

As a preferred technical scheme of the utility model, the drainage channel is in a three-section trapezoid shape, the uppermost layer of the drainage channel is provided with a drainage port which is connected with the drainage groove on the guide plate, and the drainage effect is improved by multi-section drainage, so that accumulated water is reduced.

Compared with the prior art, the utility model has the beneficial effects that: the isolating layer and the drainage plate are arranged to separate the roadbed layer from the lower substrate layer, so that the overall structure of the roadbed layer and the substrate layer is ensured, and the bearing capacity of the pavement is enhanced together with the support rod; the accumulated water on the road surface and the accumulated water permeating into a mud layer are led out through the drainage ditch and the guide plate, the base layer of the roadbed is prevented from collapsing, and the service life is prolonged.

Detailed Description

Example 1

As shown in fig. 1 to 3, a concrete pavement is arranged above the roadbed 1, the inner side of the drainage ditch 8, the inner side and the lower side of the isolation guide plate 7 are both a basement soil layer, and the support columns 5 penetrate into the bottom of the basement soil layer. When large precipitation occurs, a large amount of rainwater can flow into the drainage channel 8 from a rainwater wellhead of the concrete pavement through the pavement sewer port 3 and the sewer guide pipe 4, so that the accumulation of a large amount of rainwater on the pavement is avoided. Due to the fact that ditch drainage is adopted, pipeline blockage is avoided, and the condition of accumulated water on the road surface is relieved.

As a preferred technical scheme of the utility model, when rainwater seeps downwards from the concrete pavement and continues to flow downwards through the roadbed layer 1, the isolation layer 6 can better isolate the roadbed layer 1 from the lower substrate soil layer in a humid environment, so that the relative structural integrity of the roadbed layer 1 and the lower substrate soil layer is ensured, and the bearing capacity of the roadbed layer is increased. Meanwhile, the rainwater permeating down can flow to the drainage ditches 8 at the two ends through the diversion trenches on the isolation diversion plates 7, so that the accumulated water is prevented from being remained in the basement soil layer for a long time, the contact surface of the basement soil layer and the roadbed layer 1 deforms and collapses, the pavement collapses, and the service life of the highway is influenced.

As a preferred technical scheme of the utility model, the number of the segments of the drainage ditch 8 is adjusted according to the conditions of mountains on two sides and a basement soil layer, and meanwhile, a layer of concrete is paved on the surface of the drainage ditch, so that the impact capacity of the drainage ditch 8 is increased, and the phenomenon that a large amount of rainwater falls in and is impacted for a long time to cause unsmooth drainage and cause water accumulation on part of road sections is avoided.

The roadbed 1 is a cutting filled with natural pictures and stones; the drainage ditch 8 is formed by excavation and communicated to a river or a pipeline with lower topography; the side ditch baffle 9 is changed for the concrete shape of artificial construction according to the actual condition of the road or the mountain.

Components not described in detail herein are prior art.

Although the present invention has been described in detail with reference to the specific embodiments, the present invention is not limited to the above embodiments, and various changes and modifications without inventive changes may be made within the knowledge of those skilled in the art without departing from the spirit of the present invention.
