Problems solved by technology

Resin materials have the same strength as the original bridge deck pavement, but after construction, they often need a long maintenance time, which is not suitable for the maintenance needs of rapid opening
In addition, after the pit repair, there are four construction joints between the filling material and the original bridge deck pavement. If the waterproof treatment measures are not proper, rainwater will seep down to the steel bridge deck along the construction joints, causing the filling material to break and Corrosion of steel bridge deck

Abstract

The invention relates to a steel bridge deck pavement pit slot disease repairing structure and repairing method, through a cold mixing repairing process, resin is sprayed on the bottom and the side wall of a pit slot to form a resin bonding layer, and an asphalt fiber paste is pasted on the resin bonding layer at the side part to form a load impact buffer layer; and then a resin concrete layer, aresin water blocking layer, a pit anti-cracking layer and a resin wearing layer are successively configured on the bottom resin bonding layer; according to the bridge deck pavement patching structure,the strength of a patching area can be improved, the traffic closing time can be shortened, rapid patching of the pit groove can be guaranteed, and rainwater infiltration can be isolated after construction.

Description

technical field [0001] The invention belongs to the field of bridge deck pavement, and in particular relates to a steel bridge deck pavement pit defect repair structure and a repair method. Background technique [0002] At present, due to its good strength and light weight, steel decks are more and more frequently used in bridge construction. Bridge deck pavement, as the direct functional layer of the steel bridge deck serving vehicle loads, is prone to cracks and other defects under the combined effects of loads and environmental factors. If the disease is not repaired in time, the crack disease will further develop, forming serious diseases such as potholes. The occurrence of pothole disease will affect the maneuverability of the vehicle during driving, cause the vehicle to change the driving direction, and affect driving safety. [0003] At present, the commonly used pothole repair materials can be divided into two categories: asphalt materials and resin materials. Amo...
