Cement slab scene granulation regeneration construction process

Abstract

The invention relates to a cement slab scene granulation regeneration construction process. The process comprises the following specific steps: (1) pre-crushing: a cement slab is crushed by a pickaxe machine; (2) watering by a watering cart: before the granulation crushing is performed, the watering cart is used for watering the crushed cement slab to reduce the dust; (3) cement blocks are granulated by a PTH granulator; (4) a pavement is locally mixed by a regenerator; (5) the pavement is leveled by a floor leveler; (6) the pavement is compacted by a road roller; and (7) the pavement is maintained. The process can locally finish deep crushing of old cement concrete without needing complex tools and material transporting flows of traditional construction modes; the cement slab can be added with cement to form a mixture after the granulation to prevent the weak effect of conventional stone crushing; the process realizes once solution, and is a green low-carbon process; the renewedly stabilized mixture has the characteristic of cement stabilized macadam; and a traditional cement slab pavement can be changed to a conventional cement stabilized macadam base pavement so as to bring convenience for subsequent pavement maintenance.

Description

technical field [0001] The invention relates to a road construction method, in particular to an aspect of regeneration of old cement board pavement, which is used for on-site regeneration and utilization of the old cement board pavement. Background technique [0002] With the development of my country's highway construction and the increase in traffic volume, more and more cement slab roads have entered the maintenance period and need to be rebuilt. There are three ways to deal with the traditional cement board damage to the pavement: [0003] 1) Completely remove the old pavement and discard it. This method is a more thorough solution to deal with the old cement board pavement, but this treatment method will not only cause adverse effects on the environment, but also the old cement board pavement itself has a certain material strength. If it can be recycled, it can bring economic benefits, save resources and avoid waste. [0004] 2) Cement concrete pavement crushing techn...

Problems solved by technology

Its advantage is that it can effectively use the crushed cement board material, and the particle size of the crushed cement board material can be adjusted according to requirements, but because it needs to be transported back and forth by vehicles, it will increase the fuel cost and pollute the environment
