Welded seam repaired mouth protecting sheet for direction drilling crossing and jacking pipe penetrating and positioning tool thereof

Abstract

The invention provides a welded seam repaired mouth protecting sheet for direction drilling crossing and jacking pipe penetrating and a positioning tool thereof. The welded seam repaired mouth protecting sheet comprises a plurality of protecting sheets, wherein the protecting sheets are fixedly attached to the periphery of a welded seam of a joint of an inner pipe and are uniformly distributed along the extending direction of the welded seam; the length direction of the protecting sheets is perpendicular to the welded seam; the protecting sheets are symmetrical relative to the surface where the welded seam is located; the bottom surfaces of the protecting sheets are arc-shaped surfaces; and the radian of the arc-shaped surfaces is matched with the radian of the outer wall of the inner pipe. According to the welded seam repaired mouth protecting sheet for direction drilling crossing and jacking pipe penetrating and the positioning tool thereof, the waiting time after the pipe penetrating welding is reduced, and the speed of pipe penetrating operation is improved; and the protecting sheets are positioned through the positioning tool, so that the uniformity of the mounting positions of the protecting sheets is ensured, the stress uniformity of each protecting sheet is improved, and the service life of each protecting sheet is prolonged.

Description

technical field

[0001] The invention belongs to the technical field of pipeline engineering, and in particular relates to a welding joint protection sheet for directional drilling and pipe jacking. Background technique

[0002] In the field of pipeline engineering, with the prolongation of the service life, the walls of some large pipelines will collapse or deform to varying degrees, resulting in the accumulation of impurities, affecting the smoothness of pipeline transportation, and even causing damage to the pipeline due to continuous deformation, resulting in transported goods Leakage affects the safety of pipeline transportation. In order to strengthen the pipeline and prevent it from continuing to deform, it is often used to reinforce the pipeline by means of internal pipe penetration. Since the pipeline is penetrated in the existing pipeline, for the convenience of pipe penetration, now In the existing technology, the inner pipe required for pipe penetration needs to b...
