Abstract

The invention provides an expressway expansion joint maintenance and reinforcement method, and relates to the technical field of expressway maintenance and protection. The expressway expansion joint maintenance and reinforcement method includes the following steps: taking traffic dispersion measures, preparing maintenance devices and maintenance special tools, and removing water-stopping belts; demounting broken intermediate beams; demounting broken structures in expansion joint boxes; polishing and repairing supporting cross beams; cleaning, repairing and reinforcing the expansion joint boxes; manufacturing fixing trays of lower supports to be installed; assembling expansion joint box structures; mounting the intermediate beams; mounting the water-stopping belts; and cleaning a construction site, and opening to traffic. The method occupies part of lanes in a maintenance and construction process, will not stop traffic, can ensure the construction traffic safety at a high degree, can fasten the expansion joint cross beams by using intermediate beam lifters to perform excessive compression on upper supports of the cross beams in the expansion joint boxes, can use horizontal adjustment plates to fasten and level the expansion joints, can ensure flatness of the intermediate beams after installation is completed, and can allow the maintained expansion joints to posses durability andgood appearances, is low in maintenance difficulty, is fast and reliable, and is significant in social benefit.

Description

technical field [0001] The invention relates to the technical field of expressway maintenance and protection, in particular to a maintenance and reinforcement method for expressway expansion joints. Background technique [0002] Expansion joints of highway bridges are deliberately reserved structures during the construction of highway bridges, mainly to prevent factors such as temperature changes from affecting the safety of highway bridges. It is required that the expansion joints can freely expand and contract in two directions parallel to and perpendicular to the bridge axis, and are firm and reliable. The vehicles should run smoothly without sudden jumps and noises; they should be able to prevent rainwater and garbage from infiltrating and blocking; installation, inspection, and maintenance , Elimination of dirt should be simple and convenient. With the development of my country's expressway business and the rapid growth of traffic volume, the expansion joints construct...
