Precast concrete bridge deck pavement method

Abstract

The invention discloses a precast concrete bridge deck pavement method. A pavement device comprises supporting columns; the upper surfaces of the supporting columns are fixedly connected with a bridgefloor bottom layer; inserting grooves are formed in the upper surface of the bridge floor bottom layer; the inner wall of each inserting groove is connected with an inserting plate in a sliding manner; sliding strips are fixedly connected to the lower surfaces of the inserting plates; paving plates are fixedly connected to the upper surfaces of the inserting plates; first clamping plates are fixedly connected to the side faces of the paving plates; second clamping plates are fixedly connected to the front surfaces of the paving plates; and an asphalt layer is fixedly connected to the upper surfaces of the paving plates. According to the precast concrete bridge deck pavement device of an assembly type short T-shaped beam, the supporting columns, the bridge floor bottom layer, the insertinggrooves, the inserting plates, the sliding strips, the paving plates, the first clamping plates, the second clamping plates, the asphalt layer, water drainage grooves, connecting layers, surface layer and gravel layers are adopted, so that the precast concrete bridge floor of the assembly type short T-shaped beam can be convenient to repair and replace in a later period.

Description

technical field [0001] The invention relates to the technical field of building bridge decks, in particular to a prefabricated concrete bridge deck paving method. Background technique [0002] As the protective layer of the bridge and the surface layer to withstand the rolling of the wheels, the bridge deck pavement is laid on the top of the main girder. At present, the country is vigorously promoting prefabricated buildings, but in the field of concrete bridges, the research on prefabricated structures is mainly concentrated on the main girder and substructure, and there is less research on bridge deck pavement, and the cast-in-place method is still used today. Sometimes in the manufacture of fabricated short T-beams, some designers often pour the pavement directly on the main beam, that is, to make the flange plate thicker, so as to save the construction period. [0003] However, there are serious shortcomings in pouring the pavement directly on the main beam. Once the pa...

Problems solved by technology

[0003] However, there are serious shortcomings in the method of directly pouring the pavement on the main beam. Once the pavement layer is broken or damaged, it is not convenient for later repair and replacement because it is integrated with the main beam.
