Abstract

The invention relates to a frame box culvert jacking structure of an underpass railway, and relates to the technical field of box culvert jacking construction.The frame box culvert jacking structure comprises a plurality of box culvert pieces, a first jacking mechanism and a second jacking mechanism, the box culvert pieces abut against one another in the horizontal direction, the first jacking mechanism comprises a plurality of hydraulic jacking pieces, and the hydraulic jacking pieces are arranged on the ground; the hydraulic jacking parts are arranged at equal intervals in the horizontal direction, the length directions of the hydraulic jacking parts are parallel, the hydraulic jacking parts are used for stretching out and drawing back and pushing the box culvert parts, and the second jacking mechanism is arranged on the ground and used for pushing the box culvert parts to move in the horizontal direction. The moving directions of the box culvert pieces pushed by the first jacking mechanism and the second jacking mechanism are perpendicular to each other. The box culvert jacking device has the effect that the occupied space of box culvert jacking construction is small.

Description

technical field [0001] The present application relates to the technical field of box culvert jacking construction, and in particular, to a box culvert jacking structure and a construction method for a lower railroad. Background technique [0002] Box culvert jacking technology is used in the construction of railways and other areas. For the bottom end of the railway, the railway is not easy to be damaged and dismantled. It is necessary to dig a channel under the railway to connect the space on both sides of the railway. Box culvert jacking can be used. Technology is complete. [0003] The relevant box culvert jacking structure includes a box culvert and a jacking mechanism. The box culvert is formed by pouring concrete on a steel cage. The box culvert is a concrete structure with a channel in the middle. The jacking mechanism includes multiple hydraulic cylinders. The cylinder is set horizontally, and the cylinder body of the hydraulic cylinder is fixed on the ground. The c...
