Embodiment shall fall within the protection scope of the present invention.
The defect of conventional pipeline instrument is not caused by instrument and equipment itself, is a kind of at the beginning of the appearance of conventional pipeline Detection Techniques
Good Detection Techniques, its success have benefited from the current situation of society: backward in economy to make the pipeline closely bound up with city not
It is very intensively, laying depth is shallower.But with the rapid development of society, pipeline is more and more intensive, and laying depth is deeper and deeper, pipe
Line detecting devices constantly closely follows the step of technology development, constantly releases new model, by simulative display (Lei Di PN) to number
It shows (Lei Di 400 is commonly called as RD-II type), the power of transmitter is also increasing (10W of RD8000), and frequency is also by original normal
8K, 33K, 65K develop to both direction: high frequency 83K, 131K, 200K etc. are even with height；Low frequency 640,512 etc. is even more
It is low.Popular says to measure pipeline data information, sets about nothing more than in terms of two: first is that increasing power, but the method is bound to
It causes noise to increase, influences the accuracy of data；Second is that increasing frequency, but with the increase of frequency, signal is decayed quickly, environment
Interference increases；Reduce frequency, signal is very slow with decaying, but echo signal is difficult to distinguish, and detection accuracy decline is equally difficult to obtain
Accurate pipeline data.
Currently, the geophysical prospecting methods such as geological radar, magnetic method, gyroscope check means as the supplement of pipe and cable detector.
1) the shortcomings that geologic radar detection pipeline
(1) geological radar (Ground-Penetrating-Radar, abbreviation GPR) method is applied to during difficult pipeline reconnoitres
Premise physical property condition is that relative dielectric constant ε r for needing exploration targets pipeline and periphery medium, propagation velocity of electromagnetic wave v exist
Different, and the bigger radar signal of difference is more obvious.
(2) according to above theory it can be appreciated that for different exploration targets bodies, in different geological conditions and not
Under same Geophysical background, it is necessary first to consider to use different antennas, and pass through field test and determine the suitable day of selection
Line can just obtain best effect of reconnoitring in this way, but the selection of antenna is difficult to solve.
(3) if the depth of objective body exceeds ground penetrating radar investigation depth 50%, geological radar method effect
It is bad.
(4) objective body geometric shape (size and whereabouts) must be as clear as possible, the geometric shape of objective body include length,
Width, height, the size of objective body determine the resolution ratio that ground penetrating radar may have, and are related to the choosing of center of antenna frequency
With.If objective body is nonequiaxial shape, needs to make clear its trend, tendency and inclination angle, be related to the laying of survey line.
Above-mentioned 4 points summarize disadvantage of the geological radar in conventional pipeline detection substantially, but these disadvantages are in ultra-deep pipeline
Detection (being greater than 6 meters) is especially prominent.
2) the shortcomings that magnetic method detects
Magnetic method mainly seeks pipeline location using the magnetic contrast of ferromagnetic material in metallic conduit and surrounding medium, lacks
Point is mainly by the following aspects:
(1) pipeline is generally embedded in city, everywhere ferromagnetic material, is removed outside fixed ferromagnetic material, electricity
Solenoid line, automobile passed through at random even bicycle etc. all can carry out serious magnetic disturbance to surveying tape.
(2) currently without the mature magnetometer dedicated for detection metallic conduit.
(3) means for suppressing magnetic disturbance lack.
(4) software that Yao Kaifa detects dedicated for magnetic method, so that detection result visualizes, process is more intuitive, and work people
Member is easy to debate knowledge target pipeline.
Above-mentioned 4 points summarize disadvantage of the magnetic method in conventional pipeline detection substantially, but these disadvantages are in ultra-deep pipeline detection
In available part solve, can be applied to during ultra-deep pipeline visits with the development of technology, obtain reliable data.
3) disadvantage of the gyroscope in pipeline detection
Gyroscope is introduction of foreign technology recent years, maximum the disadvantage is that needing although detection pipeline precision is higher
It puts in a skylight on pipeline and (cuts off the water, stops the supple of gas or steam), gyroscope is placed in pipeline, by manual control, is walked in pipeline, according to
Property of gyroscope obtains the attribute data (plan-position, laying depth) of pipeline, and implementation condition is harsh, it is big to influence, and cost is high.
