Drum core drill

At present, there are two common: tube cutter drill (for medium hard rock and gravel), core drill bits tube (for hard rock and large boulders). In barrel coring drill bit in two categories, and with and without coring device to take points of core devices, depending on the difficulty of coring. Because cone core drill is mainly used for hard rock drilling and drill the ring area, if the conditions can also pass on part in the installation of reverse circulation core drill bit to improve drilling efficiency. 4, belled pile diameter drill bit does not increase without increasing deep foundation piles, in order to improve the bearing capacity of single pile, the design department is often achieved through the pedestal pile, rotary drilling rig construction is expanding bottom without any changes can be construction just choose belled drill can be. Belled drill used to mechanically based, such drills are relatively simple to use and maintain, there is the open and under the open, the opening of the four-link mechanism is generally used for soil, strong winds, weathered even hard rock formations. Due to non-circulation drilling Rotary core drills bits, completion of expansion after the end of the barrel with slag slag can be.

The function of core drill bit

The rotary core drill bitsing rig features to choose if the auger core drill bits bit has to do a continuous function, can be equipped with hydraulic grab or continuous milling wheel construction. If the secondary rope winch with automatic release function, optional percussion core drill bits bit and core drill bits large diameter core drill bits  GRABBING pebbles or boulders. If equipped with gas chambers and faucets can be gas-liquid core drill bits. If equipped with dual power head or rub into the casing pipe core drill bit machine can be, which is to solve the flow of sand, crushed gravel, silt layer effective construction method.according to the choice of a number of other factors core drill bits if Shen ballast thickness requirements more stringent or belled during core drill bitsing, the need to fight with dedicated clean ballast. When core drill bits into the sleeves, a small gap between the core drill bits and the casing, in order to prevent and reduce the core drilling bits casing hanging touch suction effect, matching the core drill bits should have vent, with the core drill bits bit with a guide, opening and closing device as close to the center of the core drill bits, one of the best machine hand. You can also solve this problem through the use of special combination core drill bits.
