Description
Technical field
The utility model belongs to buried PE pipes tracing line detection technique field, and in particular to spike inside a kind of buried PE pipes
The leading-out wiring structure of line.
Background technology
PE pipelines are low with steel pipe due to its easy construction, construction costs ratio（Below DN300）, in the absence of corrosion leakage ask
Inscribe, to conveying the advantages of Substances Pollution is small, be widely used in recent years in the buried fuel gas transmission pipe network construction in city.PE pipelines
Although having many good qualities, low intensity is its maximum weakness, in conventional urban construction construction, due to the accurate location of pipeline
It is not fully aware of, phenomenon that is disconnected, digging leakage is dug by construction machinery very common, and the gas explosion accident thereby resulted in also when have hair
It is raw；Further, since the application of trenchless technology, generates various types of deep-buried pipelines, this has just more deepened to detect pipeline
Difficulty.
At present during buried PE gas pipelines embedment underground, in order to later without excavating the position of Detection location PE pipelines and burying
It is deep, according to《Code for design of city gas engineering》The Hes of GB50028-2006《The engineering construction of city gas transmission ＆ distribution and acceptance specification》
CJJ33-2005 requirements, it is necessary to lay a plain conductor together in company with buried PE pipelines --- i.e. tracing line.Tracing line is gold
Belong to silk after preservative treatment by weaving into a kind of metal wire that can be conductive, be generally used for embedded deeper occasion, be close to
Tubing is laid, by one of tracing line connect pulse signal just can on the ground remote measurement to signal, it may be determined that the space bit of pipeline
Put and depth and trend.Generally tracing line is laid in outside pipeline, but when non-excavating construction lays PE pipelines（Orientation
Drilling for Pipeline Crossing）, the tracing line outside pipeline can in most cases be pulled off, it is impossible to 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 pipelines interior metal tracing line, mainly
Crossover sub is moulded using the steel of pipeline, metal tracing line can't be drawn by not designing the position of steel modeling crossover sub, be caused
There is breakpoint in buried PE pipelines tracing line, the phenomenon such as imperfect, and problem is carried out to pipeline detection below and positioning belt.
In the Chinese patent of Application No. " CN201520856229.5 ", entitled " tracer and with this is disclosed
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 includes 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 first tracing line and the second end of the second tracing line are free end, when needing detection pipe
During line, the free end of tracing line component is connect into emitter, due to emitter and tracing line component formation closed-loop path, emitter hair
Penetrate signal and flow through tracing line component return emitter, but tracing line is very thin, typically only 1.5-2.5 mm2, in the mistake of laying
As long as somewhat having some brickbats, tile, land waste in journey, tracing line can all be broken, the shortcoming of the tracer be once
There is breakpoint in tracing line, after the phenomenon such as imperfect, will be unable to determine the accurate location of pipeline by tracing line follow-up mechanism.And go out
After existing buried PE pipelines tracing line is pulled off, for later Detection location the need for, in addition it is also necessary to wear a gold again inside pipeline
Belong to tracing line.In this case, how the tracing line inside pipeline is drawn for applying detectable signal, and combustion gas can not be caused again
