Underpass railway frame box culvert jacking construction device and construction method thereof

Abstract

The invention discloses an underpass railway frame box culvert jacking construction device and a construction method thereof. The underpass railway frame box culvert jacking construction device comprises a simple shield tunneling machine, base beams, bearing beams and cantilever beams, wherein the simple shield tunneling machine is arranged at the front end of the interior of a frame box culvert,the base beams are arranged at the top of the frame box culvert in rows, the bearing beams are arranged at the top of the frame box culvert in rows and behind the base beams, and the cantilever beamsare sleeved with the base beams in a sliding mode; and through grooves extending in the length direction of the base beams are formed in the top of the base beams, steel sleepers in sliding fit with the through grooves are arranged at the tops of the front ends of the cantilever beams, and the cantilever beams can be driven by a driving oil cylinder to extend out of the front end of the frame boxculvert so that the steel sleepers can be inserted below a steel rail to cantilever the steel rail. According to the underpass railway frame box culvert jacking construction device and the construction method thereof, integrated construction requirements of jacking while line overhead are met, so that the jacking construction process can be effectively simplified, the operation on a line and the influence on traveling are reduced, the safe operation of a railway can be ensured, and the advantages of high mechanical construction degree, short construction period and low construction cost can beachieved.

Description

technical field [0001] The invention belongs to the technical field of jacking construction of a frame box culvert passing under a railway line, and in particular relates to a jacking construction device and a construction method of a frame box culvert passing under a railway line. Background technique [0002] With the rapid development of urban construction and roads, the existing railways often need to be rebuilt or some engineering facilities need to be built, and the frame bridges and culverts are passed under the existing railways, and jacking construction technology is often used. The existing construction method of jacking the box culvert under the railway must be divided into two steps, that is, the line is elevated first, and then the jacking is excavated. The overhead beam of the line is a special construction beam. There must be supporting piles at both ends of the overhead beam. The supporting piles are very close to the line and can only be artificially dug pil...

AI Technical Summary

Problems solved by technology

The existing jacking construction technology and construction technology have the following disadvantages: 1. Manual excavation of piles near the line, overhead line, overhead demolition, and overhead fulcrum conversion are cumbersome constructions, which have a great impact on the line and pose high risks to driving safety and personal safety ; 2. Long construction period and high project cost
