Description
Technical Field
The invention relates to the technical field of long-distance pipeline construction engineering, in particular to a method for searching a pipe cleaner by two-multiplication.
Background
As is well known, in recent years, import natural gas pipelines in China are continuously opened, national backbone pipe networks are basically formed, partial regional natural gas pipeline networks are gradually improved, unconventional natural gas pipelines are developed vigorously, and a gas supply pattern of 'west gas east transportation, north gas south and south, sea gas landing and near external supply' is formed, so that related work of interconnection and intercommunication is comprehensively developed, and long-distance pipeline construction becomes an important link in the development links of China.
The long-distance pipeline construction process comprises the following steps: measuring and paying off → cleaning of construction operation belt, building construction pavement → transportation of anti-corrosion pipe → processing groove → pipe redistribution → pipe orifice preparation, pipe orifice assembly → pipeline assembly welding → welded junction inspection → heat shrinkable sleeve (belt) opening repair → pipe ditch excavation → pipeline discharging → pipe orifice assembly, pipeline welding → welded junction inspection → pipe cleaning, diameter measurement, pressure test, pipe cleaning → pipe ditch → landform recovery.
At present, the link of cleaning and measuring the diameter in the construction engineering of the long-distance pipeline is the most painful for people, and is also a link of discolouring which is worried by the constructors of the long-distance pipeline, the trouble is that the ball is blocked in the link, the ball-searching link after the ball is blocked is a difficult, complex link of looking at the face and combining and transporting the qi. The traditional ball finding mode is that a tracker is used for finding, the receiving distance of the tracker is 3.6m, but the receiving distance is even less than 2m (due to the influence of the surrounding environment) through an actual test, an operator needs to stop at a distance of about 1.5m, and judges whether a pig is at the position by observing whether a pointer of the tracker rotates, the pipeline through ball length is about 20km generally, and the long through ball pipeline length can reach 35km, so that the efficiency of the traditional ball finding mode is extremely low. The landform on the long transmission pipeline line is not a Ma plain, other complex landforms such as a pond, a river, a highway, a protective tree and the like are arranged on the line, and when the pipeline passes through the places, a traversing means such as a top pipe and a horizontal directional drill is needed, so that the buried depth of the pipeline is far more than 2 meters, the buried depth of the pipeline in some places is more than 5 meters, and the tracker is in a failure state, so that the situation that the position of a pipe cleaner is not found as long as the tracker is used for walking once is caused, the pipeline needs to be walked once again or other more complex measures are caused, and certain use limitation is realized.
