Grouping and air-pairing installation method for corridor

Abstract

The invention discloses a grouping and air-pairing installation method for a corridor, and relates to a high-altitude installation method of a steel structure. The grouping and air-pairing installation method comprises the installation steps: carrying out detailed composition on the terrain of a site and the positions of surrounding buildings, and determining main factors restricting the lifting of the corridor; determining the type and the position of a tower crane; dividing the lower layer of the M-2 corridor into two sections for installation; carrying out corridor pairing; assembling parts of the corridor. The grouping and air-pairing installation method disclosed by the invention has the advantages that in a construction area, the operating radius of the tower crane is large, the use is flexible, the long-term use can be achieved, the steel-structure construction is carried out in the areas with narrow construction sites and disadvantage for working of large lifting equipment, and convenience is brought for grouped splicing of the large steel structure. The grouping and air-pairing installation method disclosed by the invention also has the advantages that the problem that long-term matching and construction of the lifting equipment are needed due to the limitation to the construction site can be effectively solved, the use is flexible, and the use expense of the large lifting equipment is reduced; multiple constructions can be matched for optimizing other construction projects during the use period, so that the efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of high-altitude steel structure installation, and in particular provides an aerial group installation method for corridors, which is suitable for the situation where the construction site is limited and various factors restrict large-scale hoisting equipment from being able to perform its functions. Background technique [0002] Domestic mature and relatively simple steel structure installation process: [0003] 1. Corridor grouping air docking process: This process is to split the corridor into several groups of small corridors from the ground, each group is hoisted independently and assembled in the air. [0004] The advantages of this process: safety, less use of large hoisting machinery, fast assembly speed, guaranteed quality, can be used in small construction sites, high flexibility, and get rid of the changing constraints on site. [0005] Disadvantages: Before the final removal of the hoisting equi...

AI Technical Summary

Problems solved by technology

[0005] Disadvantages: Before the final removal of the hoisting equipment, it may cause occupational impact on adjacent buildings, and the steel structure will be assembled more times in the later stage, and the construction period will be long

Disadvantages are: large-scale hoisting equipment entry and exit fees and rental costs are high, and large-scale hoisting equipment needs to prepare a spacious construction site for on-site assembly
