Preparation method of prefabricated asphalt concrete surface layer coil and coiling equipment thereof

Abstract

The invention discloses a preparation method of a prefabricated asphalt concrete surface layer coil. The preparation method includes the steps of step 1, surface layer aggregate pretreatment; step 2,surface layer aggregate sorting and storage; step 3, surface layer raw material preparation; step 4, surface layer curling; and step 5, fixed-distance cutting. The invention further provides coiling equipment for preparing the prefabricated asphalt concrete surface layer coil. Compared with the prior art, the preparation method of the prefabricated asphalt concrete surface layer coil has the beneficial effects that a pre-pressing mechanism composed of a rolling shaft, a connecting rod and a shovel plate is additionally arranged at the front end of a curling device, and when materials are poured on a conveying belt, and a baffle is used for limiting the materials, so that the materials are prevented from collapsing from the baffle; when the materials make contact with the shovel plate connected with the front end of a fixing base, the shovel plate shovels out the materials exceeding the height forwards, so that the materials are prevented from being too thick; and a rolling shaft installed at the lower end of the fixing base is used for being matched with the materials to pre-press the materials, so that the materials are pressed to a certain degree, and a curling mechanism at the rear end can conveniently process and separate the materials.

Description

technical field [0001] The invention relates to the technical field of road surface construction, in particular to a method for preparing a prefabricated asphalt concrete surface course roll, and at the same time, the invention also relates to a curling device for a prefabricated asphalt concrete surface course roll. Background technique [0002] Traditional pavement construction technology requires on-site mixing, paving, rolling and other processes. It requires the cooperation of various construction teams and long-term traffic control. Compared with life and travel, the use of prefabricated pavement greatly reduces the harm to the natural environment and the requirements for the traffic environment. Compared with prefabricated cement pavement, prefabricated asphalt concrete pavement has the advantages of less maintenance requirements, comfortable driving and low noise. [0003] At present, pavement construction usually mixes, paves, and rolls asphalt mixture on the constr...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a preparation method of prefabricated asphalt concrete surface course and its curling equipment, adding the curling equipment composed of cutting assembly, conveyor belt, pre-pressing mechanism, curling mechanism and bracket, which can prefabricate asphalt concrete surface course The advantage of being able to reduce the maintenance period in the later period is that it solves the problem that in the existing technology, on-site maintenance takes a certain amount of time, and debris is likely to affect the road surface formation during the maintenance process.
