Description

TECHNICAL FIELD

[0001] The utility model relates to the field of pipe jacking and deviation rectification treatment device, concretely relates to a soft weak stratum pipe jacking and deviation rectification treatment device. BACKGROUND

[0002] With the rapid development of urban rail transit in China, the traffic network is dense, shallow buried projects increase, and construction safety risks increase, and the pipe curtain method is widely used because it can effectively reduce the influence on the surrounding environment in high-risk source sections. The core process of the pipe curtain method is pipe jacking construction. Because the cost of a shield machine is relatively high, the traditional pipe jacking machine is still used in many pipe jacking projects at present. However, the traditional pipe jacking construction has some shortcomings. First, the jacking force required for pipe jacking is provided by the pipe jacking machine, which can easily cause the pipe jacking machine to malfunction due to excessive jacking force. Second, in non-homogeneous soil layers, the pipe jacking is easy to deviate from the existing axis, and it is difficult to rectify, which brings inconvenience and hidden dangers to subsequent projects.

[0003] The existing soft weak stratum pipe jacking and deviation rectification treatment device uses a hydraulic jack to pull back the deviated pipe in order to install the pipe in the right direction. Although the above method can achieve the effect of pulling back and rectifying the pipe, it needs to use a pulling back plate to fix and pull one end of the pipe when the device is used for a long time. When the steel cable is used to pull the pipe, the steel cable is easy to shift on the pulling back plate, which causes the stress on the left and right ends of the pipe to be different, and thus causes the pipe to tilt during pulling back, affecting the subsequent secondary operation of the pipe. In the process of directly pushing the pulling back plate by the hydraulic jack, the pulling back plate directly contacts the ground, which wastes a certain amount of pushing force and produces a lot of noise. In addition, the device has a large overall volume and is not convenient to carry to the construction site at any time. UTILITY MODEL CONTENTS

[0022] (Three) beneficial effects

[0023] Compared with the prior art, the utility model has the following beneficial effects:

[0024] To address the issue of existing pipe jacking pullback and correction devices in soft soil formations, hydraulic jacks are used to pull back misaligned pipes for proper installation. While this method effectively pulls back and corrects pipe misalignment, long-term use requires a pullback plate to secure one end of the pipe. When using steel cables to pull the pipe, the cables are prone to shifting on the pullback plate, leading to uneven stress on the left and right ends of the pipe. This can cause the pipe to tilt during pullback, affecting subsequent secondary operations. Furthermore, when using hydraulic jacks to directly push the pullback plate, the plate directly contacts the ground, resulting in a certain amount of thrust. The previous design addressed the issues of waste, excessive noise, and bulky size, making it inconvenient to carry to the construction site. This invention addresses these problems by designing upper and lower limit slots. When using ropes, these slots on the pull-back plate limit the steel cable, effectively preventing displacement and ensuring smooth pipe pull-back. Furthermore, the self-locking caster wheel design allows for piston-driven movement of the pull-back plate, reducing noise and friction on the ground, thus improving efficiency. The screw and locking nut design also allow for easy disassembly and storage. Attached Figure Description
