Abstract
The invention discloses an impacting-resistant and abrasion-resistant concrete prefabricated road. The impacting-resistant and abrasion-resistant concrete prefabricated road comprises four prefabricated boards. Holes where steel strands are contained are formed in the two sides of the prefabricated boards respectively. The adjacent prefabricated boards are connected through the steel strands. The diameter of the steel strands is 14.50 mm. Or holes where the steel strands are contained are formed in the four sides of the prefabricated boards, and the adjacent prefabricated boards are connected through the steel strands. The four prefabricated boards form a road surface unit through the corresponding steel strands and steel connecting board bands on the outer sides of the prefabricated boards. Connecting key structures are further installed between the adjacent prefabricated boards. Each connecting key structure comprises a shearing-resisting convex key and a shearing-resisting concave key which are matched. The prefabricated boards are made of cement, coal ash, sand, water, nylon fibers, barium nitrate, calcium lignosulphonate, silicon carbide powder, sepiolite powder, alumina silicate fibers and gypsum.
Description
technical field [0001] The invention relates to an impact-resistant and wear-resistant concrete pre-installed road. Background technique [0002] my country's economy is currently in a period of rapid development. A large number of roads of various grades are built every year, and a large part of them are concrete roads. At present, the domestic concrete road mainly adopts the construction technology of cast-in-place concrete, which requires construction processes such as on-site support of formwork, binding of steel bars, concrete pouring, and concrete curing. The main disadvantages of the cast-in-place concrete production process are as follows: [0003] The production efficiency is low, a lot of human resources are consumed, and the construction period is long. The on-site construction mainly adopts manual work, and the product quality is not easy to guarantee. The environmental pollution is large, and the on-site concrete pouring produces noise, sewage, waste and othe...
