Embodiment Construction

[0016] The present invention will be further illustrated below in conjunction with the accompanying drawings and specific embodiments. This embodiment is implemented on the premise of the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0017] like figure 1 As shown, a construction method for rapid maintenance and replacement of modular expansion joints includes the following steps:

[0018] 1) Construction preparation: prepare all required mechanical equipment, and implement traffic closure at the construction site where expansion joints will be replaced;

[0019] 2) Concrete removal: first use professional mechanical equipment to chisel off the original loose surface concrete at the construction site, and use special powerful cleaning equipment to remove debris when chiseling to the hard layer of concrete; On the si...

Abstract

The invention discloses a modular-type telescopic seam fast repairing and replacing construction method. The modular-type telescopic seam fast repairing and replacing construction method comprises the step of construction preparing, specifically, needed mechanical equipment is well prepared, and traffic closing is conducted on the construction site of replacing telescopic seams. According to the modular-type telescopic seam fast repairing and replacing construction method, a scientific maintenance program is worked out through professional technical service, appropriate measures are achieved, and the repairing quality is ensured; through professional seamless butt joint construction, the operation time of each process is compressed to the utmost extent, and especially the time of cleaning waste seams by using special equipment; damaged telescopic seams are replaced with a new type telescopic seam product; and 3h fast hard concrete is used, and the maintenance time is shortened.

Description

technical field [0001] The invention relates to installation, maintenance and replacement of road expansion joints, in particular to a construction method for rapid maintenance and replacement of modular expansion joints. Background technique [0002] During the operation of the bridge, the expansion device is the key component to bear the load. Under the repeated action of the rolling load of the vehicle, it is very easy to cause damage, which seriously threatens the safety of driving. Once the telescopic device is damaged, it needs to be repaired as soon as possible to ensure driving safety. However, it will be very dangerous and troublesome to carry out the operation without completely interrupting the traffic. It is very important to formulate, how to analyze the cause in detail according to the damage form of the expansion joint, prescribe the right medicine, and formulate a scientific and reasonable maintenance plan to avoid repairing and repairing again; on the other ...
