A construction method for transporting beams through railway transition

Abstract

The invention relates to a construction method of beam transportation through the transiting of a railway. The construction method comprises the following steps of prefabricating a steel platform; paving protecting steel plates; casting a concrete temporary abutment wall; subsequently connecting beam transportation roads on two sides; paving a square timber wood panel structure; emplacing the traction of the steel platform; paving sleeper piers in gaps of the platform, and placing bevel steel shores at two ends; enabling a beam transportation vehicle to pass through the steel platform; disassembling the steel platform; disassembling the sleeper and the bevel steel shores; disassembling the square timber board; disassembling the concrete temporary abutment wall; disassembling the protectingsteel plates; restoring lines and the like. According to the construction method of the beam transportation through the transiting of the railway disclosed by the invention, the difficult problem that during the construction of a city bridge, a beam transportation vehicle can safely and quickly pass through a conventional railway when the influence of the operation of the conventional railway isreduced. The construction method disclosed by the invention adopts a series of technical measures, so that the safety of tracks of the conventional railway and relative facilities in the whole construction process is guaranteed; the transportation safety of the beam transportation vehicle is guaranteed; the construction risk is reduced; the investment cost is saved; and the beam transportation efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of municipal engineering construction, and in particular relates to a construction method for transferring beams by railway. Background technique [0002] With the continuous development of urbanization, the existing urban road traffic can no longer meet the current traffic needs, so a lot of reconstruction, expansion, and new urban road traffic are needed. The construction of facilities has been basically perfected, which has resulted in a large increase in the cross-traffic conditions of new (reconstructed) urban highway lines and existing railways. In the past, the intersections of roads and railways usually used level crossings. When the trains passed through the above-mentioned level crossings, the roads were temporarily cut off. However, with the acceleration of the speed of railway trains and the increase of transportation volume, the poor safety of such level crossings and the drawbacks that affect ...

AI Technical Summary

Problems solved by technology

In the construction process of the upper-span method, the newly-built highway bridge faces the situation that there are many urban and rural buildings on both sides of the railway, which affects the passage of beam-carrying vehicles. Urban and rural roads are difficult to meet their traffic conditions

If the bypassed Yunliang Road is built, the demolition needs to be reorganized, the cost is too high, and the construction period cannot be guaranteed; if a new temporary crossing is used, it is not conducive to driving safety, and the construction cost is high, and the construction period is long, so the construction period cannot be guaranteed
