Description
Technical field
The invention belongs to PE pipe tracing line detection technique fields, and in particular to a kind of extraction of buried PE pipe inside tracing line
Wiring construction and its mode of connection.
Background technique
PE pipeline is since its is easy for construction, project cost ratio steel pipe low (DN300 or less), there is no corrosion leakages to ask
Topic pollutes the advantages that small to conveying substance, is widely used in the buried fuel gas transmission pipe network construction in city in recent years.PE pipeline
Although having many good qualities, low intensity is its maximum weakness, in previous urban construction construction, due to the accurate location of pipeline
It is not fully aware of, dug that disconnected, to dig the phenomenon that leaking very common by construction machinery, and gas explosion accident resulting from also Shi Youfa
It is raw；Further, since the application of trenchless technology, produces various types of deep-buried pipelines, this has just more deepened to detect pipeline
Difficulty.
At present when buried PE gas pipeline embedment underground, in order to not have to excavate the position of Detection location PE pipeline later and bury
It is deep, according to " Code for design of city gas engineering " GB50028-2006 and " engineering construction of city gas transmission & distribution and acceptance specification "
CJJ33-2005 requirement, needs to be laid with a plain conductor together in company with buried PE pipeline --- i.e. tracing line.Tracing line is gold
Belong to a kind of metal wire of the silk after preservative treatment by weaving at energy conduction, is generally used for embedded deeper occasion, is close to
Tubing laying, by one of tracing line connect pulse signal can on the ground telemetering to signal, it may be determined that the space bit of pipeline
It sets and depth and trend.Tracing line is laid in outside pipeline under normal circumstances, but (the orientation when non-excavating construction lays PE pipeline
Drilling for Pipeline Crossing), the tracing line outside pipeline can be in most cases pulled off, and can not be used further to apply signal detection pipeline
Position and buried depth, and lose tracing line effect.In the prior art, the extraction of buried PE pipeline interior metal tracing line, mainly
Crossover sub is moulded using the steel of pipeline, the position for not designing steel modeling crossover sub can't draw metal tracing line, cause
There is phenomena such as breakpoint, imperfect in buried PE pipeline tracing line, carrys out problem to subsequent pipeline detection and positioning belt.
Application No. is in the Chinese patent of " CN201520856229.5 ", disclose it is entitled " tracer and have should
The utility model patent of the line device of tracer ", wherein the tracer includes: protection pipe and at least one tracing line
Component, each tracing line component include the first tracing line and the second tracing line, the first end of the first tracing line and the second tracing line
First end be connected, the second end of the second end of the first tracing line and the second tracing line is free end, when needing detection pipe
When line, the free end of tracing line component is connect into transmitter, since transmitter and tracing line component form closed circuit, transmitter hair
It penetrates signal and flows through tracing line component return transmitter, but tracing line is very thin, generally only 1.5-2.5 mm2, in the mistake of laying
As long as slightly having some brickbats, tile, land waste in journey, tracing line can all be broken, the shortcomings that tracer be once
After phenomena such as breakpoint, imperfect occurs in tracing line, the accurate location that pipeline is determined by tracing line follow-up mechanism will be unable to.And go out
After existing buried PE pipeline tracing line is pulled off, for the needs of later Detection location, it is also necessary to wear a gold again inside pipeline
Belong to tracing line.In this case, how the tracing line inside pipeline draws for applying detectable signal, and can not cause combustion gas
Pipe leakage becomes urgent problem, this brings certain difficulty to the detection work of tracing line.Therefore it is urgent to provide
Tracing line draws electric wire connecting junction to solve the above problems inside a kind of simply and effectively buried PE pipe.
