Double-layer continuous paving construction process for road construction

Abstract

The invention belongs to the technical field of road construction, and particularly relates to a double-layer continuous laying construction process for road construction. A paver adopted in the construction process comprises a fixing frame, a first rolling wheel, a second rolling wheel, a feeding rod, a control box and a lengthening unit; the lengthening unit comprises a first air cylinder, a push plate, a second air cylinder and a plurality of annular screw rods; and the multiple annular screw rods are arranged in the control box in the direction parallel to the feeding rod, and the annularscrew rods at the two ends make contact with the side wall of the control box and the side wall of the push plate correspondingly. The working range of the feeding rod is extended through cooperationof the fixing frame, the first rolling wheel, the second rolling wheel, the feeding rod, the control box and the lengthening unit, and the cement macadam mixture paved by the annular screw rod is rolled by the first rolling wheel and the second rolling wheel, so that the flatness of the cement macadam mixture on a roadbed is guaranteed, and the overall use effect of the paver is further enhanced.

Description

technical field [0001] The invention belongs to the technical field of road construction, in particular to a double-layer continuous paving construction technology for road construction. Background technique [0002] The entire section of the expressway crosses other traffic lines in the form of three-dimensional intersections, and connects with other important highway lines at appropriate locations; when the lines pass through large cities, they usually pass around the city. Tunnel forms are connected; the planar alignment of expressways is mostly circular curves plus transitional curves, and attention is paid to the three-dimensional alignment design in horizontal, vertical, and horizontal three-dimensional spaces. The road surface is mostly made of hard materials with high polishing value (such as improved asphalt) to reduce the phenomenon of slippery and water jetting on the road surface. Curb strips are sometimes paved with a different color material than the road surf...

Problems solved by technology

[0004] In order to make up for the deficiencies of the existing technology, to solve the damage phenomena such as potholes, ruts, and peeling during the use of the road, and in the paving process of the road, when the road width is from small to large, the paver is paving When paving, it is necessary to stop running every time a section of working distance is passed, and the working range of the paver is expanded, which seriously affects the working efficiency of paving. This invention proposes a double-layer continuous paving construction technology for road construction.
