Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] Such as figure 1 As shown, the steel pipe jacking device includes a relay ring 1 and an oil cylinder 2.

[0021] A group of oil cylinders 2 is installed on the relay ring 1 , and each oil cylinder 2 forms an inclination angle with the radial centerline of the relay ring 1 . The inclination is 5°. The two groups of oil cylinders are arranged symmetrically with 10 and 10 respectively. Two oil cylinder annular pipelines are respectively connected with 10 oil cylinders 2 . The machine head can be rotated left and right, the correcting torque is rated at 240t·m, and the maximum is 300t·m.

[0022] The other structures and water-tight seal processing of the relay room are the same as the combined relay room. The post-processing is the same as the general relay room.

[0023] The anti-twist working principle of the present invention:

Abstract

The invention relates to a torsion correction device of a steel push pipe, which comprises a relaying ring and oil cylinders, wherein two groups of oil cylinders are installed on the relaying ring, and each oil cylinder and the radial center line of the relaying ring form an inclination angle. The inclination angle is 5 degrees; the two groups of oil cylinders are symmetrically arranged at interval of 10 oil cylinders, each 10 oil cylinders is connected with an annular pipeline of the oil cylinders, and the deviation correction moment of the respective left rotating heads and the respective right rotating heads of the two groups of oil cylinders is 240-300 tons*meter. The device can solve the technical problem existing in the torsion correction of the single-side pressurization counterweight and has the characteristics of convenient and practical construction and good effect.

Description

technical field [0001] The invention relates to pipe jacking equipment for building construction, in particular to a steel pipe jacking twist correction device for correcting the twisting of pipe jacking. Background technique [0002] Due to factors such as pipe jacking passing through different soil layers along the line, pipe jacking correction, uneven equipment layout on both sides of the pipe, and uneven layout of the main pusher jack on the rear seat, the pipe will be twisted to varying degrees during propulsion, which directly affects the smooth progress of pipe jacking and seriously will cause the pipe to twist and deform. [0003] Part of the jacking pipe twisted more than 60°; the pipe was deformed, the trunk was twisted and damaged, and it was difficult to walk inside the pipe. In order to effectively prevent the twisting of the pipeline and effectively correct the twisting, twist indicator needles are set on the tool tube and the relay ring before jacking. Equip...
