Original Title: Popular Science of Equipment-Types and Working Principles of Pile Drivers (Hot Spots) Good evening, everyone. Recently, there was a piece of news saying that the Shenzhen subway tunnel was pierce gearbox is vertically vibrated up and down through the high-speed rotation of the eccentric wheel, thereby achievinilty soil and other soil layers, and is widely used in the construction of cast-in-place piles, diaphragm walls, foundation reinforcement and other foundations. The rated power of the rotary drilling rig is generally 125 ~ 450kW, the power output torque is 120 ~ 400kN · m,dth hammer bit, the maximum hole diameter can reach 1.5 ~ 4 m, and the maximum hole depth is 60 ~ 90 m. It can meet the requiremon feature of these equipments is that the degree of automation is getting higher and higher, and some functions are realized. The application of iGPS technology on these drilling rigs realizes the automatic positioning of boom,Tapered Rock Bit, saves the time of field marking and positioning, improves the operation efficiency, and enables operatorsction pile has been widely used in soft soil foundation treatment because of its simple equipment, convenient operation, dth rock bit ,down the hole bit, lration, and the concrete is vibrated and compacted to the elevation. As a large pile driver, the vibrating immersed tube gravel pile driver has several types, such as walking tube type, walking type and crawler type, and its power is commonly known as 60, 75, 90, 110, 120 and even 150 types. The model shall be selected according to the pile diameter, pile length and geological conditions required by the design. Vibratory sinking tube gravel compaction pile has been widely used in soft soil foundation treatment because of its simple equipment, convenient operation, low cost,dhd drill bit, fast construction and no pollution. Finally, let's put a few videos of pile driver construction, which is more straightforward: END Source: Baidu Library Push Return to Sohu to see more Responsible Editor:. wt-dthtools.com
