Railway T-beam erecting construction method based on continuous beam laying reloading points

Abstract

The invention discloses a railway T-beam erecting construction method based on continuous beam laying reloading points. A construction bridge comprises a front bridge section, a middle bridge section and a rear bridge section. The method comprises a first step of laying reloading points, and laying temporary reloading devices on the middle bridge section, a second step of loading beams on a beam transporting vehicle in a beam field; a third step of utilizing the beam transporting vehicle to transport the beams, and transporting T-beams to be erected to the reloading points; a fourth step of inversely loading the beams at the position of a continuous beam, and enabling the T-beams to be erected to be inversely loaded on a maneuvering beam-transporting flatcar; a fifth step of utilizing the maneuvering beam-transporting flatcar to transport the beams, and transporting the T-beams to be erected to be transported forwards to the position of a bridge erecting machine to feed the beams; a sixth step of utilizing the bridge erecting machine to erect the beams, and a seventh step of repeating the fourth step to the sixth step many times, and finishing the erecting process of all T-beams in the rear bridge section. The railway T-beam erecting construction method is simple in construction steps, simple and convenient to operate, low in input cost, quick in erecting speed and safe and reliable in the erecting process and can solve the problems that in an existing erecting method for inversely loading the T-beams at a bridgehead, the beam erecting progress is reduced, the working efficiency is low, the construction cost is high, and required construction devices and construction workers are too many, and the like.

Description

technical field [0001] The invention relates to a T-shaped beam erection construction method, in particular to a railway T-shaped beam erection construction method based on the arrangement of replacement points for continuous beams. Background technique [0002] During the construction of railway laying, bridge erecting machines, locomotives, flatbed cars and other supporting large equipment are usually used for laying. The span of the erected T-beam (referring to the beam with T-shaped cross-section) is generally 32 meters, and the weight of each T-beam is about 160T. In actual erection, a special beam truck is generally used for transportation. The frame base is generally set close to the existing line. At present, the railway lines under construction are characterized by a large number of bridges, and the length of the bridges accounts for a large percentage of the total length of the line. Among them, there are more and more new railways spanning existing railways, hig...
