[0034] Example

[0035] Please refer to Figure 1-Figure 3 This embodiment provides a construction process for pulling a PE pipe in an engineering pipeline, including:

[0036] The front end of the PE pipe 2 to be pulled is sealed with the sealing pulling head 3 and then placed in the engineering pipeline 1. Specifically, the front end 10-20 meters of the PE pipe 2 to be pulled is placed in the engineering pipeline 1. The rear end of the PE pipe 2 to be pulled is clamped to the inner wall of the engineering pipeline 1 through a limiting mechanism to prevent the PE pipe 2 from deviating relative to the engineering pipeline 1 when pulling the PE pipe 2;

[0037] A traction rope 4 is passed through the engineering pipeline 1, one end of which is located outside the engineering pipeline 1 and connected to a power mechanism, which includes a power locomotive. The other end of the traction rope 4 is located inside the engineering pipeline 1 and connected to a sealed traction head 3;

[0038] Inject liquid 5 into the engineering pipeline 1. The liquid 5 in this embodiment includes water, mud, etc., so that the PE pipe 2 to be pulled floats in the liquid 5.

[0039] The power mechanism is started, and the traction rope 4 is pulled by the power mechanism, so that the PE pipe 2 floating on the liquid 5 is pulled forward by the traction rope 4 to complete the traction.

[0040] The sealing traction head 3 of this embodiment is partially embedded in the front end of the PE pipe 2 to be pulled to achieve sealing. The sealing traction head 3 passes through the PE pipe 2 and is threadedly connected with the sealing traction head 3 to achieve fixation.

[0041] When the PE pipe 2 is actually pulled, the buoyancy of the liquid is used to suspend or float the front end of the PE pipe in the liquid of the engineering pipeline. The front end of the PE pipe is sealed with a sealing traction head and pulled forward by a traction rope, which reduces the processes of track installation and guide wheel fixing, making the construction more convenient. The rear section of the PE pipe is fixed outside and fixed in position by a limiting mechanism to prevent deviation, so as to facilitate the connection of a new PE pipe at the rear end of the PE pipe.

[0042] like Figure 1-Figure 3 As shown, in some embodiments of the present invention, the limiting mechanism includes a limiting clamp ring 7 and a plurality of telescopic components arranged at intervals along the outer wall of the limiting clamp ring 7 in the circumferential direction. The limiting clamp ring 7 is located inside the engineering pipeline 1, and the telescopic components abut against the inner wall of the engineering pipeline 1, and the PE pipe 2 slides through the limiting clamp ring 7. The telescopic component includes a base 8 fixed to the outer wall of the limiting clamp ring 7 and a fixed sleeve 9 fixed to the base 8, and the fixed sleeve 9 is threadedly connected with a screw 10; one end of the screw 10 is located in the fixed sleeve 9, and the other end of the screw 10 is located outside the fixed sleeve 9 and is provided with a pad 11, and the pad 11 abuts against the inner wall of the engineering pipeline 1.

[0043] The present invention provides a limiting clamp ring 7 and a telescopic assembly, and the inner diameter of the limiting clamp ring 7 is slightly larger than the outer diameter of the PE pipe 2, so that the PE pipe 2 can pass through the limiting clamp ring 7 and slide, and the limiting clamp ring 7 can limit the PE pipe 2 to prevent the PE pipe 2 from deviating relative to the engineering pipeline 1 when the PE pipe 2 is pulled. When installing the limiting mechanism, each screw rod 10 can be rotated according to the actual interval, and the position of the pad 11 at the end of the screw rod 10 can be adjusted by sliding the screw rod 10 relative to the fixed sleeve 9, so that the pad 11 is tightly against the inner wall of the engineering pipeline 1, so that the limiting mechanism is conveniently fixed to the inner wall of the engineering pipeline 1.

It is obvious to those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and the present application can be implemented in other specific forms without departing from the spirit or basic features of the present application.

[0045] Therefore, no matter from which point of view, the embodiments should be regarded as illustrative and non-restrictive, and the scope of the present application is limited by the appended claims rather than the above description, and it is intended that all changes that fall within the meaning and scope of the equivalent elements of the claims are included in the present application.
