Drilling rig spud before what kind of work you want to (1) drilling rig spud before checking various machinery equipment in good condition, how to sell 100 drilling rig, mud adequacy of preparation, water and electricity pipes is smooth, in order to ensure normal. (2) before the official first start drilling mud pumps, making it idle for some time, to be a certain amount of slurry input port, the official drilling. (3) Start drilling footage speed control, to be drilled to the lower casing 1m, then at normal speed drilling. (4) drilling operations carried out continuously without interruption. Reason to stop drilling in the opening stamped shield, Shangzhi 100 drilling rig, and the proposed tunnel drill to prevent burying drilling, while maintaining a high degree of surface mud hole and mud weight, viscosity to meet the requirements. Drilling rig is now more common. Engineering drill rig is often slippery. Drilling rig drill slipping below the reasons we have to learn more about the next. One reason, it will enhance the muck out the reversal after the main volume, when drilling in the mud or on the water bucket to mention how much money 100 drilling rig, as mud or water have a certain resistance, this resistance will drill hopper muck produce a downward force, due to the drilling tube is tapered drill bucket, auger drilling footage of excessive lead to internal fighting muck squeeze dense enough, the master volume to a rapid, leading to infighting slag Soil fall out! So not every fight is not closed bottom sediment can fall out ... Two reasons, skidding fall at this time of the muck that has lost its integrity compacted soils, so after the second drill, 100 type drilling rig manufacturers, sharp teeth directly into the muck bucket bottom surface drill direct pressure on muck, rotary drilling with drill bucket, put the fall in the muck and the gap is completely uneven compaction, when muck can not be compressed, flat bottom is muck hold, fighting tooth is rotated to repeatedly draw in a long trench. At this three-layer, the first layer is rotated repeatedly drill bucket, the second layer is not only falling muck: sandwich, the third layer is not cutting through the compacted soils, since the drill bucket in line with the diameter of the hole, drilling rotation of the lever nor the resistance → No reaction → → no added pressure friction-free, bottom sediment and falling in the water or mud lubricated, then slipping phenomenon.
