High-speed rail bridge deck waterproof and protective layer construction technology
Author:
In the construction of the waterproof and protective layer of the high-speed rail bridge deck, the problem of narrow space construction is encountered, and the efficiency and quality are improved through mechanization, aiming at the problem of only 2.1 meters of narrow space in the middle of the bridge deck of the Xiongshang high-speed rail and the slope of the four sides in the middle of the drain hole, the conventional large-scale machinery cannot be used, so it needs to be solved by miniaturized, modular and intelligent equipment.
The waterproof protective layer process of high-speed rail bridge deck is a series of mechanized construction through base surface treatment, polyurethane primer, waterproof membrane pavement, concrete protective layer paving and leveling, surface treatment and cutting expansion joints after initial setting, and intelligent health preservation.
It solves the problem of multi-process collaborative construction in ultra-narrow space, provides a continuous and optimized process for the construction of waterproof protective layer on the bridge deck of high-speed rail, and provides an advanced, intelligent and standardized construction scheme for the waterproof and protective layer pavement of high-speed rail.
