Select the rotary drilling rig drill hole has a certain stiffness in the drilling rig when drilling or other operations, no moving and shaking, drilling installation shall comply with the manufacturer's standards. The construction can be equipped with short spiral drill, rotary bucket, core drill rigs Tai'an, core rotary drill bits, and other specifications. Construction, according to the following provisions choose a different auger drill bit depending on the soil and geological conditions: short spiral drill for clayey soil above the water table, silt, filling, medium dense than sand weathered rock. Spiral turret, using Slurry Wall for the clayey soil above the water table, silt, sand, fill, gravel soil and weathered rock. Core auger for gravel soil, moderate hardness of rock and weathered rock. Core drill for rock and weathered rock cracks. Bit specification by the user according to the actual construction of the purchase option. How rotary drilling rig rotary drilling rig rope to select before choosing the slope rope rig, rotary drilling rigs must understand the types and characteristics of the rope. Such models can not be determined for the use of the type of wire rope, ensure construction when it is safe. Then the rotary drilling rig rope to choose how to proceed? One end of the wire rope used in rotary drilling rig with wedge fixed to the winch drum and the other end is fixed to the upper end of the drill pipe mention introducer. In the power drill head driven rotary drilling construction process, include references to the lower end of the rotation together with the drill pipe, and the upper end is not rotating, rotating drill pipe stress minimized. General purpose rope will rotate along the cord when subjected to torsional loads, so the rope itself becomes loose. If you select the anti-rotation non-rotating wire rope, wire rope for improving the life, safety of staff and equipment to increase productivity will receive a significant effect. Due to the current domestic and foreign rotary drilling rigs are not installed movable pulley rig, so the rope line pull bigger. This should be equipped with good flexibility, good abrasion resistance, anti-rotation and anti-extrusion properties of a good rope. Especially for multi-layer winding front winch drum, twist recommend using the same rope, in order to avoid the femoral produce prints.
