Arrangement method for town road

Abstract

The invention provides a town road layout method for the road field, and utilizes the method to improve part establishment of the road, characterized in that, the rain is deposited in the rain underground tube arranged on the sideway or between the roadside trees, while the rain grate is changed on the kerbstone wall, and the kerbstone is provided with a channel wall. Under the road stratum is presupposed with a underground line skid bar, and the rain sedimentation basin is laid using the double face water seepage brick. The roadbed lay of the roadway is in a concave shape to enhance the durability and the security of the roadway, enlarge the effective through capacity, and use the rain water to irrigate the crop and the flower, which has the marked advantages of small invest, high efficiency etc, and is applicable in the generalization for the urban-rural road.

Description

technical field [0001] The invention belongs to the technical field of roads, and relates to a town road layout method, and also relates to the improvement of some road facilities by using the method. Background technique [0002] Urban roads are responsible for the heavy flow of people and vehicles, and are the arteries of cities. At present, the layout format of urban roads is generally: public facilities such as driveways, sidewalks, and bus stops. An isolation zone (isolation marking line, or fence, or flower and grass green belt) is set in the middle of the driveway, and The rainwater sedimentation tank, and the rainwater underground pipeline directly connected with the rainwater sedimentation tank, the rainwater grate is installed on the water inlet of the rainwater sedimentation tank, the sewage underground pipeline is also installed under the roadbed of the driveway, and the sidewalk tree belt (or Fence separation belt); in the existing urban road layout, the curb i...

AI Technical Summary

Problems solved by technology

[0003] Since the rainwater sedimentation tank and the rainwater underground pipeline are installed on the driveway, not only the effective traffic area of ​​the road is reduced, but also because the municipal department often clears the sedimentation tank, people, tools, and vehicles occupy the driveway to hinder traffic, and the rainwater grate It is easy to be damaged by being rolled over, and there are occasional fall accidents, and all the rainwater is discharged along the pipeline and cannot be used; because the sewage underground pipeline is dug under the driveway, it affects the firmness of the subgrade layer, and the driveway is prone to collapse; the sidewalk Although the guardrail on the side serves to isolate people and vehicles, it is expensive and prone to light pollution; since the curbs are low and level with the sidewalk, vehicles are easy to drive onto the sidewalk without guardrails, bringing safety hazards to the sidewalk and pedestrians ; Because the road base of the driveway is slightly convex on the plane, and the road surface is slope-shaped, the thickness of the pavement layer is basically the same (even the middle part is thin and the sides are thick), which does not meet the driving rules of heavy vehicles, light vehicles, and non-motor vehicles. In addition, in order to cross the road, various pipelines in the city often excavate the road horizontally, digging and filling, which not only hinders traffic during construction, but also destroys the integrity and firmness of the road
