Line reinforced structure in culvert jacking process under complex existing railway line
The invention discloses a line reinforced structure in the culvert jacking process under a complex existing railway line. The line reinforced structure comprises anti-transverse piles, roadbed protection piles and line-to-line supporting piles which are arranged and distributed in sequence from the culvert in-place side to the culvert prefabricated side, the anti-transverse piles are arranged on the positions opposite to the jacking direction, the roadbed protection piles are arranged on the outer side of a roadbed, the supporting piles are arranged between the lines, a steel beam shaped like a Chinese character 'gong' is arranged on the tops of the anti-transverse piles, the roadbed protection piles and the line-to-line supporting piles, a supporting system used for reinforcing rails is arranged on the steel beam shaped like the Chinese character 'gong', and left side overhead rails, right side overhead rails, middle overhead rails and longitudinal steel beams which are each shaped like a Chinese character 'gong' are arranged on all lines in a matched and parallel mode to keep the stability of the lines; in addition, the roadbed is reinforced in the mode of grouting the roadbed, and operation safety of the existing railway line in the jacking process is guaranteed.
