Hoisting system used for overall transportation of Bailey bridge and construction method of hoisting system

Abstract

The invention belongs to the field of overall hoisting of bailey bridges, and particularly relates to a hoisting system used for overall transportation of a Bailey bridge and a construction method ofthe hoisting system. The hoisting system mainly comprises a bracing structure, a diagonal bracing structure, a reinforcement structure, hoisting components and a hoisting device. The bracing structurecomprises at least two bracing steel parts and is horizontally mounted on a long-side truss of the Bailey bridge. The diagonal bracing structure comprises diagonal bracing steel parts and is obliquely arranged and mounted between the bracing steel parts and the long-side truss of the Bailey bridge in a bridging manner. The hoisting components are mounted at the two ends of the bracing steel partsin pair. A hoisting device comprises a lifting hook, steel wire ropes and head mast equipment. The reinforcement structure mainly comprises A-shaped steel plates, B-shaped steel plates, C-shaped steel plates, fixed components and stiffened plates. The hoisting system can be repeated; the defect that in the overall hoisting process of existing Bailey bridges, only Bailey bridges small in erectionheight and span and light in mass can be hoisted is overcome; and the defects that stability is insufficient, the danger coefficients are large, and hoisting work cannot be repeated are overcome.

Description

technical field [0001] The invention belongs to the field of integral hoisting of Bailey Bridge, in particular to a hoisting system and construction method for the overall transportation of Bailey Bridge. Background technique [0002] The Baishiyao hub ship lock project includes the construction of the second-line ship lock and the reconstruction of the first-line ship lock. The section size of the main corridor of the second-line ship lock lock wall is 3.5m*4.8m (width*height), and the total length of the 10 sections of the standard lock chamber is 16.8*10*2=336m , the section size of the main corridor section of the lock wall of the first-line ship lock is 3.0m*4.0m (width*height), and the total length of 6 sections of the standard lock chamber section is 16.8*6*2=201.6m. Among them, the ground connection wall of the longitudinal cofferdam of the second-line ship lock of the Baishiyao hub ship lock project passes through the maintenance gate of the old Baishiyao ship lock ...

AI Technical Summary

Problems solved by technology

[0003] During the construction process, the 36m section of the Bailey Bridge needs to be moved away from the 36m section of the Bailey Bridge several times during the hoisting of the steel cage of the S12 section. For the overall hoisting operation of the Bailey Bridge with a small span, steel wire ropes are generally used to tie the trusses to the overall hoisting of the Bailey Bridge. No mature hoisting device has been found; therefore, at this stage, the overall hoisting of the Bailey Bridge only works It can hoist and erect the Bailey bridge with low height, small span and light weight, and the overall stability of the Bailey bridge is not easy to guarantee during the hoisting process, and the risk factor is relatively large, so repeated hoisting work cannot be carried out. The existing The hoisting operation cannot guarantee a high-safety and high-efficiency construction process, which is not conducive to the development of the Bailey bridge application field
