Overpass outer wall facility overhauling method

Abstract

The invention belongs to the technical field of highway maintenance construction, and particularly relates to an overpass outer wall facility overhauling method. The method comprises the following steps that equipment enters a field, and an overhauling support is conveyed to a starting point of a road section to be overhauled; the equipment is assembled, a movable track and a hanging mechanism areassembled together, a traction rope is arranged in place, and a scaling ladder is rotated to the side back onto a pulley; overhauling is performed; the equipment is disassembled. According to the principle, a section of movable track is introduced on the basis of an existing walking type scaling ladder, the pulley and the movable track are high in matching degree, the walking resistance can be lowered to the maximum extent, meanwhile, a traction driving mechanism is convenient to arrange, a person on the scaling ladder can independently control the scaling ladder to walk, the labor cost is lowered, and the construction efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of road maintenance and construction, and in particular relates to a method for overhauling facilities on the outer wall of a viaduct. Background technique [0002] With the continuous improvement of people's living standards, the number of cars is also increasing, and the traditional ground transportation can no longer meet people's daily traffic needs. Therefore, in recent years, many large and medium-sized cities are vigorously developing the construction of viaduct roads, followed by Increasingly heavy viaduct maintenance work. One of the difficulties in the maintenance of viaducts lies in the maintenance of the external wall facilities of the bridge deck, such as the maintenance of wall lamps, drainage pipes and other facilities, as well as the maintenance of bridge deck joints. In the prior art, when maintaining the above-mentioned facilities, generally a specially customized aerial ladder is stuck on...

AI Technical Summary

Problems solved by technology

The defect of this construction method is that most of the aerial ladders in the prior art can only be relatively fixed with the guardrail of the viaduct, that is to say, the construction personnel need to return to the bridge deck every time they complete the maintenance of a facility, and after readjusting the position of the aerial ladder Going down to the ladder again for construction, this kind of work efficiency is extremely low

In addition, although there are some aerial ladders with walking wheels in the prior art, this kind of aerial ladder requires other construction workers to push and pull on the bridge deck to realize the walking action, and the coordination between the aerial ladder and the guardrail is poor, not only walking is laborious , and it is difficult to ensure that the ladder and the guardrail are reliably fixed during the maintenance and construction process
