| titleOfInvention | A kind of detection front end water, gas bleeder |
| abstract | The invention discloses a kind of detection front end water, gas bleeder, it is made up of front end of releasing, gutter, seal washer and connecting portion; Front end of releasing is the cone be made up of elasticity steel, and its inner hollow, has four dewatering orifices; Dewatering orifice becomes the angle of 30 ~ 50 ° with the vertical center line of front end of releasing, and dewatering orifice is run through inside and outside front end of releasing; Connecting portion is used for connection and releases front end and equipment, and the inside of connecting portion is the retaining groove of funneling; Seal washer is rubber washer, is releasing between front end and connecting portion; Gutter is fixed and through connecting portion.When carrying out height of the water conductive fracture zone detection, when detected rock stratum be aquifer or gas-bearing formation time, press water in boring or gas are discharged by the present invention, reduce the pressure of water, gas in boring, thus effectively avoid due to hydraulic pressure in boring or air pressure too high and cause pressurized water-air to pour in working space, can guarantee that detecting devices normally works, and also ensure that the precision of detection like this. |
