Construction method of a suspended protective scaffolding

Abstract

The invention relates to the field of railway construction, in particular to a construction method for a hanging type protective scaffolding. The construction method comprises the following steps that A a design and a calculation are conducted; B an over-crossing beam plate is erected; C spare parts of the protective scaffolding are assembled; D the protective scaffolding is assembled; E the protective scaffolding is put in a place; F the over-crossing beam plate is constructed; and G the protective scaffolding is dismounted. According to the construction method, the span of the protective scaffolding is reduced, the facility cost is saved, damage to a railway subgrade does not occur, the protective scaffolding can be quickly dragged in position and separated, and the disturbing effect on railway operation is little.

Description

technical field [0001] The invention relates to the field of railway construction, in particular to a construction method for a suspended protective scaffold. Background technique [0002] With the continuous development of traffic engineering, there are more and more existing railway constructions on the upper span. When the upper span bridge structure is prefabricated and assembled, the beam and slab erection is usually carried out by blocking the railway or using the window time of the railway. The erection is usually completed on the upper span. A protective scaffolding is set up under the cross-railway. Under the protection of the protective scaffolding, constructions such as the joints of the upper-span railway beams and slabs and anti-collision guardrails are carried out. The protective scaffolding is mainly set up to prevent tools and small materials from falling during bridge deck construction. . [0003] In actual construction, the method that is often used is to ...

Problems solved by technology

[0003] In actual construction, the method that is often used is to set up columns at the foot of the slope on both sides and erect the scaffolding. However, when the span of the scaffolding is large and the height is high, it is easy to cause safety problems; The method of setting up the column foundation on the subgrade slope and erecting the scaffolding must excavate the subgrade slope, which has a certain impact on driving safety, and in the process of erecting and dismantling the scaffolding, it is necessary to use the window time of the railway many times or block it. It will cause a lot of interference to the railway operation, and the impact will last for a long time.
