Problems solved by technology

[0003] In this way of construction, the main body of the frame interchange and the retaining wall at the entrance and exit are two independent parts of the structure, which are constructed step by step. The length of the main structure is controlled according to the width of the railway shoulder. The overhead period of the line is long; during the construction of the splayed wall, it is necessary to carry out overhead protection for the railway subgrade, which has a large safety risk and is not conducive to the safety of railway operation; Completed under the overhead state of the railway, it will greatly interfere with the operation of the railway

Abstract

The invention relates to a railway integral jacking frame interchange system and a construction method thereof. In the jacking construction of an underpass interchange, the two sides of a construction frame interchange need to be constructed with an entrance and exit soil retaining splayed wall which is of an independent two-part structure, the step-by-step construction period is long, and the interference to the operation of a railway is large. The system comprises a frame body, the cross section of the frame body is rectangular, the two sides of the frame body are frame entrance and exit reinforced concrete triangular sections, a triangular steel shed frame is arranged on an inclined face, a beam top steel plate is arranged at the top of the triangular steel shed frame, and the beam top steel plate and the top of the frame body form the same sliding face. The entrance and exit reinforced concrete triangular section and the frame structure are integrally prefabricated, the stress performance is good, secondary pouring of an entrance and exit splayed wall is avoided, the frame entrance and exit reinforced concrete triangular section and the frame structure are jacked in place at a time, the construction period is short, safety is high, and good application and popularization value is achieved.

Description

technical field [0001] The invention relates to the technical field of railway jacking frame overpass construction, in particular to a railway integral jacking frame overpass system and a construction method thereof. Background technique [0002] Jacking construction is a common construction method for underpassing interchanges. Traditional railway jacking frame interchanges generally prefabricate a rectangular frame in the work pit on one side of the railway. Under the condition of removing the overhead railway line, construct the retaining walls on both sides of the frame interchange. After the prefabrication of the eight-shaped wall is completed, remove the overhead system of the railway line and resume the operation of the railway line. The entire jacking frame interchange project is completed. [0003] In this way of construction, the main body of the frame interchange and the retaining wall at the entrance and exit are two independent parts of the structure, which are ...
