Problems solved by technology

[0005] In order to make up for the deficiencies of the existing technology, due to the lack of rigorous construction methods in the groove connection of adjacent pipes, there will be differences in the processing of grooves, butt joints of adjacent pipes, and the installation of rubber seals and clamps in the later stage. The degree of problem will lead to a certain degree of water seepage at the joint of the pipeline when the pipeline is used for work in the later stage, which will affect the normal use of the problem. A construction method for pipeline groove connection proposed by the present invention

Embodiment approach

[0058] As an embodiment of the present invention, the inside of the bottom support plate 45 is provided with a movable groove 451 corresponding to the connecting rod 48, and a spring 452 is fixedly connected to the bottom of the movable groove 451; the connecting rod 48 is movably connected to the Inside the active slot 451.

[0059] Specifically, when the top support plate 41 and the bottom support plate 45 are driven away by the cylinder 46, the connecting rod 48 at the bottom of the top support plate 41 will move in the movable groove 451 inside the bottom support plate 45, and at the same time be positioned on the bottom support plate 45. The inner spring 452 will no longer be squeezed by the connecting rod 48, and when the connecting rod 48 returns to the inside of the bottom support plate 45, the connecting rod 48 will squeeze the spring 452 and make the spring 452 generate elastic potential energy.

[0060] As an embodiment of the present invention, the limit seat 47 is...

Abstract

The invention belongs to the technical field of pipeline groove connection, and particularly relates to a construction method for pipeline groove connection, which comprises the following steps: S1, pipe stabilizing preparation work before pipeline groove connection; s2, firstly, a support and a bracket for fixing the steel pipe are installed at the designated position; s3, a groove is machined in the end of the steel pipe with the specified length size through a channeling machine; s4, two adjacent groups of steel pipes are in butt joint through rubber sealing rings and are fixed through hoops and bolts; s5, after the adjacent steel pipes are connected through the grooves, fixing buttresses are built at the bottoms of the steel pipes for fixing; the construction method for pipeline groove connection is systematically and strictly formulated through the steps S1 to S5, so that when groove connection is conducted on pipelines, rigorous construction can be conducted according to the construction method, and the phenomenon that due to imperfection of many details, pipeline connection is not tight, the sealing performance is poor, and water seepage is caused in later use is avoided.

Description

technical field [0001] The invention belongs to the technical field of pipeline groove connection, in particular to a construction method for pipeline groove connection. Background technique [0002] Pipelines are an essential component in areas such as water supply and drainage, fire protection, and wind circulation. [0003] At present, the method of pipe groove connection mainly means that after the pipe joint is machined into an annular groove by a special rolling groove machine, a rubber sealing ring is put on the end of the adjacent steel pipe, and the split type clamp is used. Quick connection. [0004] In the prior art, due to the lack of rigorous construction methods when grooved to adjacent pipelines, there will be various problems in the processing of grooves, butt joints of adjacent pipelines, and the installation of rubber seals and clamps in the later stage. , leading to a certain degree of water seepage at the joint of the pipeline when the pipeline is used ...
