    Core drilling skills
    Core drilling rig is widely used in geological survey and geophysical exploration; Road and bridge construction survey; Structural quality inspection of geotechnical blasting holes, grouting holes and concrete works, drilling construction of agricultural water wells, etc. The core drilling rig is mainly composed of power, reducer, water pump, clutch and gearbox, vertical shaft box, winch and drilling tower. The most important thing to operate the core drill is experience and skills. During the construction process, when the drill pipe bit is lowered into the hole, the operation control is completely judged by the experience of the manipulator. How to cut the drilling tools of the core drill during construction is invisible, but the stress of the drilling tools in the hole will be fed back to the equipment outside the hole. For example: load and vibration, so the operator can judge the situation in the hole by observing the changes of equipment outside the hole, so as to change the operation control. The two most commonly used methods for operating core drilling rig are listening to the sound and watching the drilling rate

    Pre drilling inspection


    1. Check whether the oil level, coolant and hydraulic oil of the drilling rig are sufficient.
    2. Check whether the connecting screws of each part of the drilling machine are fastened.
    3. The oil mist shall be added in time according to the use condition (it is forbidden to use the secondary polluted oil).
    4. Check whether the left and right chains work hard at the same time and adjust them consistently
