[0023] The present invention is described in further detail below:
[0024] A wear-resistant, crack-resistant and hardened ground construction method, comprising the following steps in sequence:
[0025] 1) Surface treatment of the base layer: Wet and clean the floor by sprinkling water, first grind the surface of the base layer into a rough surface with a scraper, and then evenly apply a layer of cement slurry mixed with 801 glue for sweeping treatment. The 801 glue is Zhongnan brand, Originated in Shanghai, the weight ratio of 801 glue to cement slurry is 1:2.
[0026] 2) Die support for sub-silo: Set up glass strip compartments, the direction of the die is consistent, not criss-cross, and the width of the die in the sub-silo should be 4m ~ 6m strip interval.
[0027] 3) Pouring polypropylene fiber concrete floor with a thickness of 50mm: pour it according to the compartment, use steel rollers to roll and flatten it repeatedly, use a vacuum water absorption device to remove...
