construction method developed rapidly in China recently. Rotary drilling rig construction has many characteristics such as high efficiency, low noise, environmental protection, high hole forming quality and high degree of mechanization. Rotary drilling rig is the executor of this construction method. Whether foreign products or domestic equipment, the structural form and working principle are similar, but the construction strata are very different, The specific technical requirements for construction are different, so only by selecting different bits to meet the above requirements, scientifically selecting bits and reasonably using bits can enrich the construction technology of rotary drilling rig and broaden the construction field of rotary drilling rig to a certain extent. There are many factors affecting the selection of rotary drilling bits, which can be summarized in three aspects: formation conditions; Drilling rig function; Specific requirements for hole depth, hole diameter, ballast thickness, wall protection measures, etc. 1. At present, the classification of common rotary drilling bits includes screw bit, rotary bucket, barrel coring bit, bottom expanding bit, impact bit, impact grab cone bit and hydraulic grab. The following is a brief introduction one by one. 1. 1 spiral drill bit (1) cone: double headed double screw, suitable for hard bedrock. Double headed single screw, suitable for weathered bedrock, pebble, frozen soil, etc. The above bits are equipped with various picks, and many types of bits can be derived through the changes of tooth shape, pitch and spiral rise angle. (2) Straight screw bit: A. bucket tooth straight screw, double head double screw, suitable for small-diameter gravel layer with poor cementation in sandy soil; Double headed single screw, suitable for sandy soil and soil layer; Single head single screw, suitable for large diameter pebbles with poor cementation, cohesive soil and hard mastic. b. Pick straight screw: there are double screw, three screw and four screw, which is suitable for hard bedrock or gravel. 1. 2. Rotary drilling bucket can be divided into pick drilling bucket and bucket tooth drilling bucket according to the installed teeth; According to the number of bottom plates, it can be divided into double-layer bottom bucket and single-layer bottom bucket; It can be divided into double door bucket and single door bucket according to the number of doors opened; According to the taper of the barrel, it can be divided into conical barrel drilling bucket and straight barrel drilling bucket; According to the shape of the low plate, it can be divided into pot bottom drilling bucket and flat bottom drilling bucket. The above structural forms are combined with each other, coupled with the change of whether there is a vent and door opening mechanism, dozens of rotary drilling buckets can be combined. Generally speaking, the double bottom drilling bucket is applicable to a wide range of strata, the single bottom drilling bucket is only applicable to the soil layer with strong viscosity, the double door drilling bucket is applicable to a wide range of strata, and the single door drilling bucket is only used for large-diameter pebbles and hard
