Problems solved by technology

[0002] During the construction of Jinzhai Hydropower Station, a large amount of construction materials and equipment need to be transported. Since the existing road cannot meet the requirements of use, a temporary construction road needs to be built
The road used for temporary construction is cement pavement or asphalt pavement. This kind of road construction generally requires road base construction first, and then pavement hardening layer construction. There are many construction procedures and the time required for construction is also long; , there will inevitably be clods falling on the road surface, the traditional asphalt and concrete pavement is easily damaged, and the maintenance is troublesome
At the same time, a large amount of dust will remain on the road surface, and a large amount of dust will be generated when construction vehicles pass by, requiring frequent watering operations by sprinklers, which increases road maintenance costs
Therefore, the existing technology has the problems of long construction period, easily damaged roads, troublesome maintenance and high maintenance cost

Abstract

The invention discloses a dust prevention curing process for a temporary construction load. The dust prevention curing process comprises the following steps: step 1, curing construction of the road: A, laying and curing a lower layer road foundation; B, laying and curing an upper layer road foundation; C, sealing the upper layer road foundation and the lower layer road foundation after curing for more than 10 hours to obtain the cured road; and step 2, performing dust prevention curing construction on the cured road: spraying a dust depressor solution onto the surface of the cured road according to the proportion of 1.0-1.5 L / m[2]. According to the dust prevention curing process for the temporary construction load, the road construction period is shortened, the road damage rate is reduced, the road maintenance is facilitated, the maintenance cost is reduced, and regreening and recultivation after the road is abandoned in the later period are facilitated.

Description

technical field [0001] The invention relates to a road construction process, in particular to a dustproof and solidification process for temporary construction roads. Background technique [0002] During the construction of Jinzhai Hydropower Station, a large amount of construction materials and equipment need to be transported. Since the existing road cannot meet the requirements of use, a temporary construction road needs to be built. The road used for temporary construction is cement pavement or asphalt pavement. This kind of road construction generally requires road base construction first, and then pavement hardening layer construction. There are many construction procedures and the time required for construction is also long; , It is inevitable that there will be clods falling on the road surface. The traditional asphalt and concrete pavement is easy to damage and troublesome to maintain. At the same time, a large amount of dust will remain on the road, and a large am...
