Abstract

The invention relates to the field of oil and gas pipelines, and discloses a sealing tool and an assembly method for grouting repair of deep-buried tunnels to solve the technical problem that there is no repair tool for repairing small-scale damage to pipe joints in the prior art. The sealing tool includes: an annular sealing basic steel ring, which is connected by six arcs of the same diameter, and the six arcs of the same diameter include: the first arc of the same diameter with the longest length and the second arc of the same diameter with the shortest length Arc, each arc with the same diameter includes: steel plate body, two sealing grooves arranged on both radial sides of the steel plate body, connecting plates arranged on both sides of the transverse interface of the steel plate body and perpendicular to the splitting bevel corresponding to the same-diameter arc The inflatable sealing ring is placed in the two sealing grooves; the rubber pad is set between the connecting plates of two adjacent circular arcs of the same diameter among the six circular arcs of the same diameter, wherein the rubber pad and the corresponding connecting plate are connected by bolts fixed. The technical effect of repairing small-scale damage to pipelines by using the sealing tool is achieved.

Description

technical field [0001] The invention relates to the field of oil and gas pipelines, in particular to a sealing tool and an assembly method for grouting repair of deep buried tunnels. Background technique [0002] In oil and gas pipeline projects (such as: water supply and drainage projects, shield tunneling and pipe jacking projects), some pipelines or tunnels with relatively large depths often meet the requirements of the construction socket type and withstand sufficient water pressure. At the same time, they must also be able to To overcome certain water and soil pressure and formation deformation torsion. Due to the complex stratum with many uncertainties, coupled with the comprehensive effect of earth pressure and water pressure, there will be small-scale damage to pipe joints, water seepage, and even the possibility of water and sand gushing. A repair tool for small-scale damage to pipe joints. Contents of the invention [0003] The invention provides a sealing tool...
