In-situ cold-recycling construction process and quality control platform for cement-stabilized base layer

Abstract

The invention provides an in-situ cold-recycling construction process and quality control platform for a cement-stabilized base layer, relates to the technical field of road engineering, and solves the problems that vibration type transposition of disintegrating slag cannot be realized during crushing, and the crushing efficiency is influenced; and uniform feeding of an additive cannot be realized while crushing is carried out through structural improvement. The in-situ cold-recycling construction process and quality control platform for the cement-stabilized base layer comprises a box body. A placing structure is installed in the box body, an extrusion structure is further installed in the box body, and a driving structure is welded to the extrusion structure. Bulges B are welded on a placing seat in a rectangular array shape, and the bulges B are in elastic contact with the head end of a poke rod; and the bulge B and the poke rod jointly form a vibration structure of the placing seat so that when the placing seat moves up and down under the extrusion of the bulge A, the vibration transposition of the disintegrating slag in the placing seat can be realized through the bulges B and the poke rod, and the extrusion crushing efficiency is further improved.

Description

technical field [0001] The invention belongs to the technical field of road engineering, and more specifically relates to an in-situ cold regeneration construction technique and a quality control platform for a cement stabilized base. Background technique [0002] Semi-rigid base pavement has high strength and bearing capacity, and its later strength is high and has the characteristics of increasing with age. Therefore, semi-rigid base pavement has become one of the most important pavement structure types of high-grade highways in my country. At this stage There are a large number of old roads in our country that need to be repaired every year. The traditional grass-roots maintenance method is to stabilize the grass-roots materials with old road cement, and then reuse them after crushing. [0003] Based on the above, the existing in-situ cold regeneration construction technology and quality control platform for cement-stabilized bases still have the following defects: [000...

AI Technical Summary

Problems solved by technology

[0006] In order to solve the above-mentioned technical problems, the present invention provides an in-situ cold regeneration construction technology and quality control platform for cement stabilized base to solve the problem that the existing device cannot realize the vibrating transposition of the slag at the same time when crushing, thereby affecting the Crushing efficiency; moreover, the structure of the existing device is poor, and it is impossible to realize the uniform feeding of additives while crushing through structural improvement
