Maintenance and Reinforcement Method of Expressway Expansion Joint

Abstract

The invention discloses an expressway expansion joint maintenance and reinforcement method which comprises the following steps: shooting an image of a damaged position of an expansion joint, and inputting the image and related parameters of the expansion joint into an analysis module; enabling the analysis module to callscorresponding maintenance parameters from a pre-stored maintenance parametercontrast data set by utilizing an analysis result after analysis; manufacturing a new expansion joint device according to the maintenance parameters; manufacturing a new fixed connection beam according to the maintenance parameters; dismounting the damaged expansion joint according to the maintenance parameters; fixing the fixedly-connected beams to the side walls of the mounting groove through anchor rods anchored to the two side walls of the mounting groove, and spraying the side walls and the bottom face of the mounting groove with concrete mortar; placing the expansion joint device in themounting groove and connecting the expansion joint device with the fixedly-connected beams; welding the connecting beam to the expansion joint supporting cross beam; and opening the traffic after thecover plate is repaired. The damage degree of the expansion joint is accurately judged according to the surface damage degree of the expansion joint, and the damaged expansion joint is replaced by theexpansion joint device manufactured in advance, so that the traffic influence is small, and the maintenance is convenient and fast.

Description

technical field [0001] The invention relates to the technical field of expansion joint construction, in particular to a maintenance and reinforcement method for expressway expansion joints. Background technique [0002] Expressway expansion joints are specially reserved structures during the construction of expressways, mainly to prevent factors such as temperature changes from affecting the safety of expressways. It is required that the expansion joints can freely expand and contract in two directions parallel to and perpendicular to the axis of the expressway, and are firm and reliable. The vehicles should run smoothly, without jumping and noise, and should be able to prevent rainwater, garbage and soil from infiltrating and blocking; installation, inspection, It is easy and convenient to maintain and remove dirt. With the development of my country's expressway business and the rapid growth of traffic volume, the expansion joints built in the early stage have gradually su...

Problems solved by technology

However, there is currently no technical standard for the repair or reinforcement of expansion joints, and it is difficult to guarantee the construction quality. Diseases reappear in a short period of time after replacement and repair.

At the same time, when the expansion joint is repaired and reinforced, it is often necessary to block the traffic. The existing maintenance and reinforcement method needs to remove the expansion joint first, and then prepare related tools and replacement parts, and then repair and strengthen the expansion joint. The traffic time is long, which has a great impact on the driving of normal vehicles
