A construction method for pavement water stabilization layer and ancillary works

Abstract

The invention discloses a construction method for a road surface water stabilizing layer and an ancillary project. The construction method comprises the steps that a road trough is checked and accepted, specifically, the road trough of a to-be-constructed road section is subjected to checking and accepting; drainage construction is performed, specifically, a transverse water drainage pipe is buried, and a longitudinal gutterway is arranged; cushion construction is performed, specifically, a cushion is paved to form a bed course; road shoulders and central separating area construction is performed, specifically, slip form construction is performed on both side edges and the center of a road surface to form a shoulder strip foundation and a central separating area canalization retaining wall; the construction of earth up, greening and separation of the water stability layer is performed, specifically, the road shoulders are subjected to earth up and greening and the water stability layeris subjected to paving according to the separation of the shoulder strip foundation; anti-collision guardrail construction is performed, specifically, a New Jersey barrier is installed on a upper base layer; and surface layer construction is performed, specifically, the road surface is subjected to paving of an asphalt surface layer. According to the construction method for the road surface waterstabilizing layer and the ancillary project, a working surface of the water stability layer is not polluted, the construction image is good, the construction is compact, traffic control can be performed reliably, and the construction efficiency is high.

Description

technical field [0001] The invention relates to a road construction method, in particular to a construction method for a road surface water stability layer and ancillary works. Background technique [0002] The traditional pavement construction process is to install curb stones, earthen shoulders and greening after the construction of the water stabilization layer, and finally carry out the construction of the asphalt surface layer. This construction method has the following problems: [0003] 1. In the process of cultivating curbs and soil shoulders after the upper base is completed, cross-construction will be carried out on the upper base. Although the construction site will take a series of anti-pollution management measures for the upper base, the pollution still cannot be eliminated, and the final impact will be Sealing effect. [0004] 2. After the water stabilization layer is completed, curbstones and other auxiliary structures are produced. The production period is ...

Problems solved by technology

[0003] 1. In the process of cultivating curbs and soil shoulders after the upper base is completed, cross-construction will be carried out on the upper base. Although the construction site will take a series of anti-pollution management measures for the upper base, the pollution still cannot be eliminated, and the final impact will be Sealing Bonding Effect

[0004] 2. After the water stabilization layer is completed, curbstones and other auxiliary structures are produced. The production period is long and the site area is large. After the production is completed, the installation and construction are carried out. The construction pressure of the installation and construction is relatively high, and generally requires human sea tactics The cost of rushing to work is high, and the image of the construction site is poor; after the construction and installation of the subsidiary structures, the earthing and greening are carried out, and then the construction of the asphalt surface layer is carried out. The construction interval from the completion of the upper base layer to the asphalt surface layer is too long, and the construction is not compact

[0005] 3. During the construction process, the construction road surface looks flat and barrier-free, which makes traffic control difficult. Vehicles often pass through the middle and enter the closed health care area. Even if signs are added, it is difficult to stop

[0006] 4. It is difficult to manage the civilized construction scene during water stabilization construction, the site is chaotic, and the image is poor. There is often a saying that "the image can only be produced after the asphalt layer is applied"

[0007] 5. The construction process of artificial formwork at the edge of the water stabilization is slow, the workload of the transition is large, and the efficiency is low
