Embodiment 1

[0038] Such as figure 1 and 2 As shown, a municipal road structure includes a road body 1, and the road body 1 includes a road base 2, a gravel layer 3, an anti-filter geotextile 4, a coarse sand layer 5, and a permeable concrete layer 6 sequentially laid from bottom to top.

[0039]The road base 2 is the foundation of the pavement, which is a geotechnical structure formed by excavation or filling. In this embodiment, the road base 2 is the original soil road bed left after the foundation pit was dug for the original road. Two urban sewer pipes 7 are buried in the road base 2. The urban sewer pipes 7 are made of cement. The urban sewer pipes 7 are arranged along the extension direction of the road. The urban sewer pipes 7 are connected to the urban drainage system. The engineering facility system of urban sewage and rainwater. The urban drainage system is usually composed of several drainage pipes and sewage treatment plants buried under the road surface. Each urban sewer pip...

Embodiment 2

[0051] A construction method for a municipal road structure. The construction method for a municipal road structure provided in this embodiment is applied to a municipal road structure in Embodiment 1. The specific steps of the construction method of the municipal road structure are as follows:

[0052] S1: Excavate the foundation pit, excavate the road base 2 to bury the urban sewer pipe 7 in the road base 2, connect the urban sewer pipe 7 to the urban drainage system, and install a number of prefabricated reservoirs 13 in the city On the sewer pipe 7;

[0053] In this embodiment, the foundation pit dug out is used for paving roads, and the subgrade 2 is the undisturbed soil subgrade that remains after the foundation pit is dug, and the trench for placing the urban sewer pipe 7 is excavated on the subgrade 2. The urban sewer pipe 7 in the trench is connected to the urban drainage system, and then several prefabricated reservoirs 13 are respectively installed at the water inl...

Abstract

The invention discloses a municipal road structure and a construction method thereof. The municipal road structure includes a road body, the road body includes a roadbed layer, a gravel layer, a coarse sand layer and a permeable concrete layer which are successively laid from bottom to top, the permeable concrete layer includes a roadway, two drains arranged on both sides of the roadway and two sidewalks arranged on both sides of the two drains, the road body is internally embedded with a plurality of reservoirs, the reservoirs communicate with urban sewer lines buried in the roadbed layer, water leading pipes allowing the reservoirs and the drains to communicate are arranged between the reservoirs and the drains correspondingly, and the reservoirs are internally provided with control mechanisms for controlling communication or partition between the reservoirs and the urban sewer lines correspondingly. According to key points of the technical scheme, rainwater can not only be diffused downwards and discharged through the structure of the road body, but also be discharged through drainage structures such as the drains, the water leading pipes, the reservoirs and the urban sewer lines, the drainage performance is good, and accumulated water is not prone to forming on the road surface.

Description

technical field [0001] The invention relates to the technical field of municipal engineering, in particular to a municipal road structure and a construction method thereof. Background technique [0002] With the acceleration of the urbanization process, the level of each city is also improving, the road is becoming more and more modern, and the drainage function of the road is more and more valued by people. The drainage of the road reflects the level of the planning and design of the entire municipal road. , so it is becoming more and more important to ensure the smooth drainage of urban roads. [0003] The Chinese patent with the existing authorized notification number CN206438357U discloses a road structure, including a hard road base, a cushion layer, a sub-base, a cement sand base, a cement sand upper base, an asphalt layer and an anti-skid base laid sequentially from bottom to top. Wear-resistant layer, the road structure improves the anti-slip and wear-resistant perf...
