Foreign productsJoint development and production of rotary drilling rig mainly Bauer (BAUER), and force (SOILMEC), (IMT), Matt imgai (MAIT), Casa Grant, (CASAGRANDE), DELMAG, MGAF, Haier and Hitachi, Ingersoll Rand, Bohai - Sumitomo company. The main products are shown in table 1.
Types of rotary drilling rigThe principle of choosing a rotary drilling rig is to meet the current major engineering requirements of users and to take into account the possible engineering requirements in the future. Rotary drilling rig according to the torque, engine power, hole diameter, hole depth and the quality of the drilling machine can be divided into 3 types: Small - hole diameter 0.5-1m, drilling depth of about 40m, the quality of 40t; medium - 0.8-1.8m hole diameter, hole depth of about 60m, the quality of 65t; large - diameter drilling machine 1-2.5m the drilling depth, 80m.
Rotary drilling rig is suitable for sand and clay, silty soil layer construction, bored pile, continuous wall, foundation reinforcement has been widely used in various foundation foundation construction, mainly for municipal, road bridges, industrial and civil buildings and other infrastructure construction. The rated power of rotary drilling machine is generally 125-450kW, power output torque is 120-400kNm, the maximum diameter of the hole can reach 1.5-3m, the maximum hole depth is 60-90m, which can meet the requirements of various large-scale infrastructure construction.
