Abstract

The invention relates to a trajectory control system and method for steel pipe curved jacking. The trajectory control system for steel pipe curved jacking comprises a pipe-jacking machine head, a rectifying oil cylinder unit, a first intermediate jacking station, a second intermediate jacking station and a plurality of hinged pipes. The rectifying oil cylinder unit is arranged on the cross section of the rear section of the pipe-jacking machine head, and is used for adjusting the posture of the pipe-jacking machine head. The first intermediate jacking station and the second intermediate jacking station are arranged at the front end and the middle end of a curved section pipe joint respectively and are used for adjusting the curved radian of the curved section pipe joint. The curved section pipe joint comprises a plurality of steel pipe joints, and the hinged pipes are arranged between the adjacent steel pipe joints and are used for adjusting the curved radian of the curved section pipe joint in an auxiliary mode. According to the trajectory control system and method for steel pipe curved jacking, the hinged pipes are arranged between the adjacent steel pipe joints to reduce the rigidity of steel pipe jacking, the multiple sets of rectifying systems of the pipe-jacking machine head, the intermediate jacking stations and the hinged pipes are used for controlling the steel pipe curved jacking trajectory, and the jacked axis is made to keep the stable curvature radius.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a trajectory control system and a control method for curved steel pipe jacking. Background technique [0002] With the development of urban economy and the expansion of city scale, there are more and more constructions of various municipal projects such as subways, cross-river tunnels, and sewage pipelines. As a non-excavation construction method for laying underground pipelines, the pipe jacking construction method has little impact on the surrounding environment and relatively low cost, so it has been widely used. In the process of pipe jacking construction, with the help of jacking force from oil cylinders or jacks, etc., the roadheader is passed from the working well through the soil layer along the line and enters the receiving well. At the same time, the subsequent pipelines are connected and buried in sequence The pipeline connecting the two wells is in t...
