A kind of prefabricated concrete bridge deck pavement method

Abstract

The invention discloses a method for paving a prefabricated concrete bridge deck. The paving device includes a support column, the upper surface of the support column is fixedly connected with the bottom layer of the bridge deck, and the upper surface of the bottom layer of the bridge deck is provided with an insertion groove. The inner wall of the plug-in slot is slidably connected with a plug-in board, the lower surface of the plug-in board is fixedly connected with a slide bar, the upper surface of the plug-in board is fixedly connected with a pavement board, and the side of the pavement board is fixed A first clamping board is connected, a second clamping board is fixedly connected to the front of the paving board, and an asphalt layer is fixedly connected to the upper surface of the paving board. The prefabricated concrete bridge deck pavement device of the prefabricated short T girder is provided with support columns, the bottom layer of the bridge deck, a plug slot, a plug board, a sliding strip, a pavement board, a first clamping board, a second clamping board, asphalt Layer, drainage groove, connection layer, surface layer and gravel layer, so as to make the prefabricated concrete bridge deck of the prefabricated short T-beam easy to repair and replace in the later stage.

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.
