Abstract
The invention discloses a kind of welding manner of buried pipeline, follow these steps to carry out：Working face is dug out above buried pipeline and the pipeline welded neatly docks, it extracts to form an aperture at the top of any pipeline for carrying out welding position, weld clip passes through the aperture on pipeline, into inside pipeline, the welding of pipeline lower half is carried out in insides of pipes, after the completion of the welding of lower half, remainder is welded on the outside of pipeline, so that inner side and outer side solder joint combines, the welding of entire pipeline is completed in the aperture on welded pipe line top.The welding of buried pipeline can be rapidly completed in the present invention, have and weld easy to operate, welding efficiency height, high-quality technical effect.
Description
Technical field
The invention belongs to pipeline welding fields, and in particular to a kind of welding manner of buried pipeline.
Background technique
For buried pipeline due to being embedded in subsurface for a long time, local environment is moister, so that pipeline rots to break down, therefore,
Need to repair welding.Traditional welding manner is, such as Fig. 1, firstly, the welding that needs repairing buried pipeline 1 it is upper
A biggish working face is dug out on lower soil layer 2, working face is divided into working face 4 and lower working face 5, to facilitate staff sharp
Weld the crack 3 of buried pipeline with weld clip, when welding need to neatly dock the pipeline of welding, bending welding rod, finally, in pipeline
Outer side bottom surface start to weld, in order to preferably weld, it is sometimes desirable to mirror is placed below in pipeline, pass through observation mirror
The welding of duct bottom is carried out, such welding manner is inconvenient, and welding efficiency is low and welding quality is not high.
Summary of the invention
In view of the above-mentioned problems, the technical problem to be solved in the present invention is to provide a kind of buried pipeline welding manner, welding
Technical effect that is easy to operate, having welding efficiency high, high-quality.
To achieve the above object, the present invention uses following technical scheme：
A kind of buried pipeline welding manner, includes the following steps：
Step 1：Working face is dug out above buried pipeline and neatly docks the pipeline of welding；
Step 2：It extracts to form an aperture at the top of any pipeline for carrying out welding position；
Step 3：Weld clip is by the aperture on pipeline, into inside pipeline, carries out the welding of pipeline lower half in insides of pipes；
Step 4：After the completion of the welding of lower half, remainder is welded on the outside of pipeline, so that inner side and outer side solder joint phase
In conjunction with；
Step 5：Aperture at the top of welded pipe line, completes the welding of entire pipeline.
The buried pipe is common Coiling Welded Pipe.
The present invention provides a kind of welding manner of buried pipeline, by improving and creating on the basis of prior welding mode
Newly, an aperture for being conducive to welding is opened using in pipeline top surface, so that not only having facilitated the welding of pipeline, but also facilitates and welding
In the process to the observation of pipeline, the efficiency and welding quality of pipeline welding are improved.
Detailed description of the invention
Fig. 1 is traditional underground pipe welding manner schematic diagram.
Fig. 2 is underground pipe welding manner schematic diagram after improving.
1. underground pipe, 2. soil layers, 3. cracks, working face on 4., 5. lower working faces, 6. apertures.
Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to embodiments, to the present invention
It is described in further detail.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and unlimited
The fixed present invention.
A kind of buried pipeline welding manner, includes the following steps：
Step 1：Working face is dug out above buried pipeline and neatly docks the pipeline of welding
Step 2：It extracts to form an aperture at the top of any pipeline for carrying out welding position；
Step 3：Weld clip is by the aperture on pipeline, into inside pipeline, carries out the welding of pipeline lower half in insides of pipes；
Step 4：After the completion of the welding of lower half, remainder is welded on the outside of pipeline, so that inner side and outer side solder joint phase
In conjunction with；
Step 5：Aperture at the top of welded pipe line, completes the welding of entire pipeline；
The buried pipe is common Coiling Welded Pipe.
Such as Fig. 2, a kind of underground pipe 1 digs out a upper working face 4 on soil layer 2, then will when carrying out pipeline maintenance
The pipeline of welding neatly docks, and is carrying out extracting to form an aperture 6 at the top of welded pipe line, enter in pipeline convenient for welding fixture
Portion's fracture 3 is welded, the first welding to 1 insides of pipes lower half of underground pipe when welding, after the completion of the welding of lower half, in pipe
Remainder is welded on the outside of road, so that inner side and outer side solder joint combines, finally, the aperture at the top of welded pipe line,
Complete the welding of entire pipeline.
Using the above scheme, the welding of buried pipeline can be comparatively fast completed, has and welds easy to operate, welding efficiency
Height, high-quality technical effect.
Technology hand scheme disclosed in this invention is not limited only to technical solution disclosed in above embodiment, further include by
Technical solution composed by the above any combination of technical features.It should be pointed out that coming for those skilled in the art
It says, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also considered as this
The protection scope of invention.
