A method for in-situ overhead installation of auxiliary brackets for integral ballast bed reinforcement

Abstract

The invention discloses a method of using an auxiliary support to mount an integrated ballast bed reinforcement in situ in an overhead manner. The method of using the auxiliary support to mount the integrated ballast bed reinforcement in situ in an overhead manner comprises the steps of making tripods of two expansion joints and matched members; fixing top channel steel and inserting galvanized steel pipes into the tripods; placing longitudinal reinforcements, sleeving a hoop and binding the longitudinal reinforcements as required; inserting side reinforcements and bottom longitudinal reinforcements into the hoop and binding the side reinforcements and the bottom longitudinal reinforcements as required; pulling manual hoists at a constant speed to integrally lift the reinforcements; and putting the whole integrated ballast bed reinforcement into a foundation groove. According to the method of using the auxiliary support to mount the integrated ballast bed reinforcement in situ in an overhead manner, as the operation surface of the track foundation reinforcement project is transferred from the interior of a track foundation pit to a position right above the foundation pit by using members such as the special tripods, the galvanized steel pipes, the reinforcements, the channel steel and hooked reinforcements, the distances between the reinforcements can be preferably controlled,the binding of the reinforcements are more convenient and faster, the quality of the track reinforcement project is integrally improved, the integrated ballast bed reinforcement binding working spaceis increased, the construction period is reduced, the labor is saved, and the the construction of the integrated ballast bed reinforcement project can be rapidly finished.

Description

technical field [0001] The invention relates to the technical field of railway track concrete structure reinforcement engineering construction, in particular to a method for installing an auxiliary bracket in situ overhead for the reinforcement of an integral ballast bed. Background technique [0002] There are 1 purge line, static adjustment line, scheduled repair line, temporary repair line, turning wheel line, and test run line in the subway depot, 13 parking train inspection lines, and 2 weekly and monthly inspection lines, a total of 21 lines. There are many lines, and the integral ballast bed foundation pit is narrow. The existing construction technology is to bind the integral ballast bed steel bars in situ at the bottom of the foundation pit. [0003] The in-situ reinforcement binding of the overall ballast bed reinforcement at the bottom of the foundation pit is affected by the narrow working space. It is difficult to hoop the main reinforcement and bind the reinfor...

Problems solved by technology

[0003] The in-situ reinforcement binding of the overall ballast bed reinforcement at the bottom of the foundation pit is affected by the narrow working space. It is difficult to hoop the main reinforcement and bind the reinforcement, which is not conducive to the flow operation, and it is extremely difficult to ensure the quality.
