Embodiment

[0036] refer to figure 1, is a device for pipeline jacking construction disclosed by the present invention, including a jack 5, a jacking iron 6, a support rod 1 and a jacking head 7. Wherein, the jack 5 and the top iron 6 are arranged in the originating shaft 8, and the jack 5 offsets the pipe joint 10 through the top iron 6, and pushes the pipe joint 10 to the receiving shaft 9. The hollow support rod 1 is located in the pipeline of the curved section, and is used to maintain the extension track of the pipeline and make it difficult to deform. The jacking machine head 7 is arranged at the front end of the pipeline and offsets against the first pipe joint 10 .

[0037] refer to figure 1 , the end of the support rod 1 facing the origin shaft 8 is located in the straight pipe section 10, and the axis of the support rod 1 coincides with the pipe section 10, and the other parts of the support rod 1 are located in the three-section pipe corresponding to the curved pipe. Section...

Abstract

The invention relates to the technical field of pipeline construction, in particular to a device for pipeline jacking construction, which includes a support rod arranged in a pipe joint, and the support rod is arranged along the axial direction of a pipe joint in a straight section to support There are several groups of hydraulic cylinders on the rod, and a traction rope is connected to the support rod. The hydraulic cylinders of each group are arranged along the length direction of the support rod. There are at least three hydraulic cylinders in each group. Arranged vertically, the axis of the hydraulic cylinder points to the axis of the support rod, and the end of the traction rope facing away from the support rod is connected in the originating shaft. The invention has the effect of sharing the lateral component force suffered by the pipe joint in the curved section, so that the pipe joint can extend forward as smoothly as possible, and the pipe joint is not easy to be greatly deformed.

Description

technical field [0001] The invention relates to the technical field of pipeline construction, in particular to a device for pipeline jacking construction. Background technique [0002] During the construction of municipal or industrial pipeline projects, it is often necessary to lay many pipes of different diameters, including water pipes, sewage pipes, rainwater pipes, underground passages, gas pipes and heat pipes. The traditional method of digging trenches and burying pipes has many disadvantages, such as affecting traffic, destroying road surfaces, destroying surface vegetation, affecting normal commercial activities and daily life of residents, and bringing a lot of earthworks, etc. [0003] In order to overcome the above defects, pipe jacking construction as a trenchless construction method has gradually emerged and has been widely used in developed areas. The principle of the pipe jacking method is to use the thrust of the main jacking cylinder, the pipe room, the re...
