Construction method for adhering fiber cloth with underwater impregnated glue

Abstract

The invention relates to a construction method for adhering fiber cloth with underwater impregnated glue. The construction method comprises the following steps of washing impurities on a base surface; using a rope for distinguishing the grinding range, removing marine organisms and a loose layer, grinding off edges and corners and the concrete surface, and repairing till smoothness is achieved; cutting the fiber cloth according to the size, and preparing two layers of plastic films; uniformly mixing the glue A and the glue B; coating a plastic film with the impregnating glue, covering the impregnating glue with fiber cloth, coating the fiber cloth with a layer of impregnating glue, slicking, covering the fiber cloth with a second layer of plastic film, wrapping the fiber cloth into a small roll, and immediately putting the roll into water for later use; and driving a constructor to the pasting position to tear off the plastic film, placing one end of the fiber cloth right and slowly rolling towards the other end along the rope, scraping and pressing through a scraping plate in the filament direction, and tearing off the outer-layer plastic film one day after the fiber cloth is pasted. According to the construction method, the problems that according to an existing construction method, the accuracy of the carbon cloth pasting position is difficult to guarantee, the construction time is short, and the base plane reinforcing effect is easily affected can be effectively solved.

Description

technical field

[0001] The invention relates to the technical field of impregnating glue, in particular to a construction method for sticking fiber cloth with underwater impregnating glue. Background technique

[0002] Underwater carbon fiber impregnating glue is used for the repair and reinforcement of underwater concrete. The construction method is generally to spread the carbon cloth on the double-layer plastic film, and repeatedly roll the impregnating glue with a scraper along the fiber direction of the carbon cloth until it penetrates into the concrete. Carbon cloth, to ensure that the adhesive layer on one side of the carbon cloth is thicker, spread the other layer of the double-layer film on the carbon cloth, and then wrap the carbon cloth into small rolls according to the direction of the carbon filaments, and dive to the pasting position during construction Unfold the rolled carbon cloth, tear off the film with a slightly thicker adhesive layer, paste the carbon cl...
