Abstract

The invention discloses a bailey piece detachable steel trestle construction method. The method includes the steps of a, trestle upright pile foundation construction, b, first-layer earth excavation,c, elevation pilot testing and steel tube upright treatment, d, profile steel girder installation, e, bailey piece installation and fixing, f, secondary beam installation, g, vehicle traveling bridgedeck slab installation, h, anti-skid reinforcing rod and protective barrier welding, i, trial run conduction, acceptance check and use, j, second-layer earth excavation, k, next-layer trestle repeatedinstallation, l, horizontal pull rod and diagonal bracing installation, m, second trail run conduction, acceptance check and use, and n, maintenance and detachment. By the adoption of the construction method, assembly and disassembly are convenient, and assembly and disassembly efficiency is improved; and meanwhile, the recycling rate is increased, waste is reduced, and the manufacturing cost isreduced.

Description

technical field [0001] The invention relates to the field of construction, in particular to a construction method for a detachable steel trestle bridge with Bailey sheets. Background technique [0002] With the development of buildings towards deep, high, difficult and multi-directional, more and more deep foundation pit problems in basement construction affect the construction site, especially in the earthwork excavation stage. How to speed up the progress of deep foundation pit earthwork construction is a key construction problem. [0003] The construction period of earthwork excavation generally accounts for 1 / 3 of the construction period of the underground construction stage. Improving the efficiency of earthwork excavation and reducing the construction time of earthwork are favorable conditions for reducing the cost of underground construction. In order to improve the efficiency of excavation, temporary trestles are routinely designed as excavation channels in deep foun...
