Installation method of metro depot assembly type concrete track bridge

Abstract

An installation method of a metro depot assembly type concrete track bridge comprises the steps of installing and fixing embedded parts; producing the assembly type concrete track bridge; connecting the assembly type concrete track bridge with an embedded part in a ground structure; laying rails; and filling track cement. The installation method of the metro depot assembly type concrete track bridge has the main advantages that the installation speed is high, and the construction period is shortened; labor force and turnover material investment can be reduced, and the construction cost is low; the mounting precision is high, and the track laying requirement is met; factorization processing and maintenance are adopted, the durability of the concrete is guaranteed, the concrete is firm and durable, and the service life can be prolonged; the appearance effect is good; noise, dust and wet operation are avoided, and the civilized construction degree is high.

Description

technical field [0001] The invention relates to the field of construction, and mainly relates to a method for installing a prefabricated concrete track bridge in a subway depot. Background technique [0002] With the rapid development of my country's rail transit industry, rail transit has become the main means of transportation to ease national travel. In order to ensure the safe and reliable operation of high-speed rail EMUs and urban subways and light rails, it is necessary to establish supporting locomotives and vehicle maintenance yards. At present, the existing steel column rail bridges have high manufacturing costs, and are difficult to maintain in the later period. After long-term use, the rail bridge pillars appear rusted, which affects the safety of maintenance trains; the construction of cast-in-place concrete rail bridges has difficulties in formwork construction, rough appearance, and large volume. On-site construction quality is unstable, construction speed is...

AI Technical Summary

Problems solved by technology

At present, the existing steel column track bridge has high manufacturing cost, and it is difficult to maintain in the later period. After long-term use, the track bridge pillars are corroded, which affects the safety of maintenance trains; the construction of cast-in-place concrete track bridge has difficulties in formwork construction, rough appearance, and large volume. On-site construction quality is unstable, construction speed is slow, labor intensity is high, etc.
