Abstract

The utility model relates to a construction method for using tools to instal a rubber waterstop for a bridge expansion joint, which relates to a construction method for installing the rubber waterstopof the bridge expansion joint by the tool. It is mainly invented to solve the problem that the sealing quality of waterstop and weathering steel will be affected by the installation of waterstop at present. Firstly, the residual concrete of expansion joint is cleaned up with flat shovel. Break the plastic adhesive tape on the weathering steel mold cavity with a bending shovel; Clean the foam strip in the mold cavity at the seam of the plate with forward and backward shovels. The rubber belt is laid on the plate seam and the weathering steel, and then the rubber belt is inserted into the plateseam by manual embedding method. Insert the rubber belt against the collision wall into the weathering steel mold cavity, and insert the waterproof rubber belt between the collision wall and the track bed board into the steel mold cavity with a flat shovel; Use flat shovel to insert the waterproof rubber belt at the plate seam into the mold cavity of the profile steel so that the bottom of the rubber belt enters into the mold cavity completely. Use a lever shovel to completely insert the rubber belt into the weathering steel cavity. The construction method for using tools to instal a rubber waterstop for the bridge expansion joint has the advantages of good sealing water stopping effect.

Description

Technical field: [0001] The invention relates to a construction method for installing a bridge expansion joint rubber waterstop by using tools. Background technique: [0002] In high-speed railway bridge engineering, expansion joints composed of weathering steel and rubber waterstops are usually set between simply supported beams, which are used for simply supported beam expansion and water stop. During the construction and installation of expansion joints, the weathering steel is usually pre-embedded first, and then the rubber waterstop is installed, and the rubber waterstop is generally installed by machine stretching. This method will cause damage to the waterstop and affect the rubber waterstop. The sealing quality of the hose and the weathering steel caused water seepage at the beam end. Invention content: [0003] The technical problem to be solved by the present invention is to provide a construction method that can fully embed the rubber waterstop into the weather...
