Fabricated concrete pavement provided with tenons and construction method

Abstract

A concrete layer of the fabricated concrete pavement is formed by splicing a plurality of prefabricated concrete slabs, pull rods are arranged on the long edges of one sides of the prefabricated concrete slabs, first grooves matched with the pull rods are formed in the long edges of the other sides of the prefabricated concrete slabs, dowel bars are arranged on the short edges of one sides of the prefabricated concrete slabs, and second grooves matched with the dowel bars are formed in the short edges of the other sides of the prefabricated concrete slabs. The pull rods and the dowel bars are embedded into the first grooves and the second grooves of the adjacent prefabricated concrete slabs correspondingly so that the adjacent prefabricated concrete slabs can be assembled. A plurality of tenons are longitudinally arranged at intervals at the bottom of the precast concrete slab, matched mounting grooves are formed in the positions, corresponding to the tenons, of the pavement structure base layer, and the tenons of the precast concrete slab are embedded and locked in the mounting grooves of the pavement structure base layer; and joint filling treatment is carried out on joints between the assembled precast concrete slabs. The common cement concrete plate and the reinforced cement concrete plate can be prefabricated in a factory and assembled on site, the construction speed is high, and the construction period can be greatly shortened.

Description

technical field [0001] The invention relates to the technical field of road engineering, in particular to an assembled concrete pavement. Background technique [0002] Cast-in-situ is the main construction method of cement concrete pavement at present, but its construction and maintenance period is too long, which is not conducive to speeding up the construction progress and ensuring the timeliness of opening to traffic. Prefabricated concrete pavement can effectively solve this problem while ensuring strength. In recent years, my country has vigorously developed prefabricated concrete buildings in line with the development concept of "innovation, coordination, green, openness, and sharing" and in accordance with the requirements of "applicability, economy, safety, greenness, and beauty". There is still a lack of research and promotion in one direction. [0003] At present, the only design ideas for prefabricated concrete pavement mainly include the following: (1) The edge o...
