Long spiral bored doing the job belongs to non-soil compaction pile areas, with long spiral auger drilling machine in a pile located at the place of cutting soil, clods are cut with the drill cuttings rotation, along with spiral blade drill rise automatically out of the hole, drilled to a depth after pneumatic high-pressure injection pump design, slightly lift the drill pipe, using concrete pump, concrete along the high-strength hose, drill core tube into the hole in the side lift irrigation side until openings or design of pile top elevation above 0.5m, then steel cage into the hole, hydrostatic and vibrators, the steel cage to a predetermined position [1]. It features an electric high-pressure injection pump, vibration, low noise, not disturbing, drilling speed, no slurry pollution, low cost, simple equipment, easy construction, good pile quality and easy control, strong adaptability to formation and, if necessary, adjust the pressure, the pile diameter in the range of 300-600 adjustable drilling depth is generally 18m, 24m, currently up to 30m [2] 1 rig safety rules, before the rig into the room, you must acceptance Specifications and carefully check the support situation room, equipment room specifications meet the construction requirements, support reliable high-pressure injection pump, cap tightly. 2, before the rig into the room, you must carefully check the engine room and roof support conditions and the situation near the roadway, roof overhang refuse to pick the next time with Changgan tools and real top pick, if roadway deformation, supporting material deterioration , shed legs broken and must be replaced in advance, to strengthen support. 3, the rig operator before operating the rig to rig to integrity and security checks, find faults or safety hazards promptly notify the maintenance man maintenance treatment. To rig maintenance man in charge of each working day to check the integrity of the rig, identify problems in time. 4, rig workers must be familiar with the business operations, certificates, prohibited the use of high-speed, in order to avoid some of the man-made catastrophes. 5, tools, accessories and other items should not be placed on the rig Mine high pressure injection pump, 6, during construction, the driller must be certified, not free to leave the rig, construction workers must wear clothing line with national standards for protective overalls, must be worn neat and cuffs, skirts, trousers fastened to avoid involvement belt clothes and other rotating parts hurt. 7, when operating the rig roughnecks, must stand before the operation panel, left hand on the stop button at the right hand operation, so that "Three Views", "two", "one time", that is, to see the operating handle vibration, feed pressure and footage speed, see pump pressure gauge and backwater situation, look at the situation belts and faucet fittings; listen to the sound operation of the machine, listening to the sound hole vibration; abnormal timely stop drilling process. Light high-pressure injection pump, high-pressure injection pump Beichen, Tianjin high-pressure pump to find the cohesive strength Jet rig provided by the Tianjin-strong high-pressure pump Limited. Tianjin-strong high-pressure pump Co., Ltd. (www.tjjuqiang.com) strong, credible, in Tianjin's piling machinery industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead-strong Jet rig into the brilliant and you work for a better future!
