Wet jointed shaped steel mold prefabricated assembled prestressed reinforced concrete pavement

Abstract

The utility model belongs to concrete pavement technical field, specifically is a kind of wet jointed shaped steel mould prefabricated assembly type prestressed reinforced concrete pavement, including bottom base, the bottom base is located at the top side of roadbed, and prefabricated pavement slab and wet joint structure are provided on the sliding layer;The method and structure of quick slab hoisting can be carried out by self-researching hook, make construction more convenient, and maintenance time is short after construction, maintenance method is simple, traffic is recovered fast, has good economic benefit on-site use popularization nature is very high;In order to ensure that concrete long plate occurs shrinkage crack before prestress is applied, tension control stress should be converted according to the size of tension force based on the calibration result of jack, tension control stress x75%, is the ultimate tensile strength of prestressed reinforcement;Fine sand polyethylene sliding layer is arranged in sliding layer, plays certain cushioning effect while reducing pavement friction resistance, can effectively reduce the generation of pavement disease, improve pavement durability.
