Abstract

The invention provides an expansion joint waterproof structure for bridge engineering construction, relates to the technical field of bridge engineering, and solves the problems that auxiliary fixation with a bridge body and elastic looseness prevention of fixing bolts cannot be realized while expansion is met, and multiple waterproofing and contraction buffering cannot be realized through structural improvement. The expansion joint waterproof structure for bridge engineering construction comprises a bridge bodies; the number of the bridge bodies is two, the two bridge bodies are rotationally connected through a connecting plate, and a waterproof plate and a baffle are installed between the two bridge bodies. Grooves A are symmetrically punched in the waterproof plate, and the grooves A match clamping grooves. The grooves A are connected with the clamping grooves in a clamped mode, and the grooves A and the clamping grooves jointly form an auxiliary connecting structure and an auxiliary water blocking structure of the two bridge bodies and the waterproof plate.

Description

technical field

[0001] The invention belongs to the technical field of bridge engineering, and more specifically relates to a waterproof structure for expansion joints in bridge engineering construction. Background technique

[0002] At present, bridge expansion joints refer to the intervals set between the ends of two bridge decks, between the ends of bridge decks and abutments, or at the hinge positions of bridges. The thermal expansion and contraction between the abutment and the abutment meet the deformation requirements of the bridge deck.

[0003] For example, the application number: CN202010774189.5, the present invention provides a waterproof structure for expansion joints in traffic bridge engineering construction, including bridges and expansion joints distributed on the bridge. The bridges on the opposite side of the two asphalt pouring layers are horizontally and longitudinally overlapped with fixed base plates. In the present invention, the fixing effect is ac...
