Abstract

The invention provides a construction method for cast-in-place of a continuous beam at a turnout junction for a passenger transport line in a seawall area by a false work method. The construction method comprises the steps of processing a foundation, erecting a bracket, pressing the bracket in advance, mounting a support base, mounting a template, processing and mounting reinforcing steel bars, distributing corrugated pipes, casting concrete, constructing prestress, grouting a pipeline and sealing anchor. According to the construction method, the false work is applied to the construction of the continuous beam at the turnout junction of the passenger transport line engineering in the seawall area along the coast, the work procedures of bracket construction and prestress construction are innovated according to the geological conditions and self characteristics of the continuous beam, and by the proving of the practice, the construction of the continuous beam for the passenger transport line in the seawall along the coast achieves good effects, and the acceptance standard of the passenger transport line is met.

Description

technical field

[0001] The invention relates to the field of bridge construction for railway passenger dedicated lines, in particular to a construction method for continuous beams of turnouts for passenger dedicated lines in coastal seawall areas. Background technique

[0002] With the rapid development of my country's economy and society, the construction of railway bridges in various regions of the country is also developing rapidly. With the increase of capital flow, technology flow, people flow, service flow and space expansion, the passenger transport volume will increase significantly, and fast , comfortable and safe service. These are the advantages of dedicated passenger lines, and the rapid development of rapid rail transit between cities.

[0003] At present, my country's railway continuous beam construction technology is relatively complete, but there is no mature construction method for continuous beam construction of passenger dedicated lines in coastal seawall ...
