Description
Technical field
The present invention relates to a kind of boring with the defogging method boring geology imager.
Background technology
Hole with boring geology imager for the various structure structures in observation boring directly perceived, in execute-in-place process, because borehole temperature is high and add water for cooling, in boring formation initial stage hole, water smoke is larger, cannot effectively be eliminated in the existing defogging method short time, cause survey meter imaging effect not good, effectively available technical data can not be provided for production practices.
And for the water smoke in boring, mainly there is several processing method: 1. air chimney directly presses wind to clear up; 2. wait for and dissipating voluntarily; 3. artificial treatment.But said method has the following disadvantages:
(1), in said method, air chimney directly presses wind to clear up water smoke in boring, and because air pipeline diameter is much smaller than bore diameter, air-flow can not evenly shed, and air turbulence in hole, water smoke not easily sheds.
(2) in said method, to wait in hole that water smoke required time of dissipating voluntarily is long, the water smoke rate that sheds is not high, seriously reduces operating efficiency, and passes boring collapse hole phenomenon in time and increase, and causes imaging probe cannot detect in boring.
(3), in said method, manually adopt sponge, paper scrap etc. to wrap up bar head and put in hole, absorb water smoke in boring, labour intensity is large, and efficiency is low.
For solving the problem, the water smoke around reduction imaging probe, on the impact of its imaging effect, improves the environment for use of survey meter, and spy proposes a kind of drill hole geologic with the defogging method boring imager.
Summary of the invention
For the problems referred to above, the invention provides a kind of boring with the defogging method boring geology imager, effectively remove the impurity such as water smoke, dust, ensure that the effect of imaging.
In order to solve the problem, technical scheme provided by the invention is:
Hole with the defogging method boring geology imager, comprise the following steps:
(1) be provided with some ventholes, the axis oblique of this venthole and described imaging probe tube wall in boring with on the imaging probe tube wall boring geology imager, angle is 5-30 to spend;
(2) utilize air duct by described venthole and underground ventilating pipeline communication, and gas flow optimized valve is installed on air duct, close described gas flow optimized valve;
(3) boring is pushed in boring with the imaging probe boring geology imager;
(4) open described gas flow optimized valve, in described air duct, pass into gases at high pressure, water smoke, dust around described venthole ejection high pressure draught removing imaging probe.
Preferably, imaging probe comprises tempering transparent glass tube, and the airflow direction in described venthole blows to described tempering transparent glass tube.
Preferably, holing is connected with imaging probe signal by cable with the main frame boring geology imager, and described air duct one end and described underground ventilating pipeline communication, mid portion is placed in described cable, and the other end is communicated with described venthole.
The mid portion of air duct is placed in cable, well by aerating system together with imaging system compatibility, also avoid causing unnecessary interference because additionally increasing air duct to imaging job; Install, use all convenient.
Preferably, on described cable, cover has distribution of air flow ring, and this distribution of air flow ring is placed in imaging probe, and described air duct is communicated with described venthole by described distribution of air flow ring; Be convenient to installation, ventilation, use.
Preferably, described air duct is also provided with air gauge, according to the water smoke situation in boring, utilizes described gas flow optimized valve to adjust the size of blast.
Preferably, the angle of the axis oblique of described venthole and described imaging probe tube wall is 15 degree.
Preferably, the quantity of described venthole is 8, and the circumference along described imaging probe tube wall is uniformly distributed.
Compared with prior art, beneficial effect of the present invention is:
Defogging method of the present invention not only overcomes that single water filling wash boring effect is undesirable, cost is high, easily generate the shortcoming of water smoke in hole, and have the advantage of note gases at high pressure wash boring concurrently, and easy defogging method is combined with imaging system, enhance the compliance of whole detection system to environment; And the operation of detection system, not by the restriction of demist time, at utmost avoids collapse hole dangerous; The visual field blooming occurred in detection process can be solved, improve detection precision, have broad prospects in bore detecting fields such as underground coal mine geological prospecting hole, gas extraction hole, leting speeper hole, grouting and reinforcing holes.
