Construction method of suspended scaffolding operating platform for maintenance and repair of active bridges

Abstract

The invention relates to a construction method for an active service bridge maintenance suspension type scaffold operation platform. The construction method mainly comprises the steps of construction preparing, steel wire rope and suspension rod mounting, operation platform assembling, operation platform hoisting, platform plate laying, sliding rail and electric operation ladder mounting, protective frame mounting, box beam bottom plate repairing, maintenance operation platform lifting, box beam web and top plate maintaining, and equipment dismantling according to the inverted mounting order after qualifying of acceptance. Steel wire ropes and adjustable suspension rods are adopted to suspend the maintenance operation platform, so that platform overall lifting is achieved by extending and retracting of the adjustable suspension rods while the stability of the platform is strengthened, the influence on water surface navigation is reduced, and good technical and economic benefits are achieved.

Description

Technical field [0001] The invention relates to a construction method of a suspended scaffold operating platform for the maintenance and repair of an active bridge, which belongs to the field of bridge engineering and is suitable for the maintenance and repair construction of an active bridge. Background technique [0002] In recent years, the development of my country's highway transportation construction is obvious to all. The high-speed development of highways also brings follow-up operational problems. With the increase of traffic volume, especially the continuous increase of heavy-duty vehicles, as well as some problems in maintenance and management, a series of damage and diseases have appeared in the early construction of highway and bridge structures in my country. Some diseases have even seriously affected the structure. Safety and durability. In order to ensure the safety and quality of the engineering structure, it is necessary to strengthen the maintenance and managem...

AI Technical Summary

Problems solved by technology

[0003] At present, the maintenance and repair of old bridges usually use suspended scaffolding construction platforms. The suspended scaffolding construction platforms usually use steel wire ropes (or chain hoists) installed on the anti-collision walls on both sides of the bridge to suspend the steel truss platform, and then install it on the platform. Setting up maintenance scaffolding for maintenance work, this process has low construction cost, and the platform is relatively simple to erect, but the safety is low, the steel wire rope is easy to shake, resulting in poor platform stability, and it affects the navigation time for a long time, and the movement of the construction platform is only It can be carried out by water, and the rental cost of the boat is very high, which greatly increases the construction cost
