Steel sheet pile in China more and more practical, so driven steel sheet pile driver development, then we come to the following popular steel sheet pile knowledge. Piling machine is the use of impact force will pile into the formation of pile of machinery. The main types of piling machine are hammer piling machine, hammer piling machine, diesel hammer piling machine, hydraulic vibration hammer piling machine and other four categories, the following we come to detailed description of the type of steel sheet pile driver introduction and shortcoming analysis:
1.Hammer piling machine, pile hammer is a steel weight, by the hoist with a hook to lift, decoupling along the guide frame free fall and piling.
Advantages and shortcomings analysis: drop hammer type piling machine suitable for playing a variety of piles, simple structure, easy to use, the impact of large, free to adjust the pitch, the deficit is slow hammer speed, low efficiency.
2.Steam hammer piling machine, pile hammer by the hammer and hammer seat composition to steam or compressed air as the driving force, a steam hammer and double dynamic steam hammer two single-hammer to the plunger or cylinder as a hammer, steam-driven hammer up, and then let it along the hammer seat guide piles and piling.
When the pile into the formation of vibration, can reduce the friction resistance, piling effect, two-way differential force hammer, the hammer weight is light, the effective impact to the weight can be impact increased, better performance.
The change of the steam hammer into the steam valve can be controlled, but also by the hammer side and with the hammer up and down the flange control lever automatic control, two ways can adjust the impact of the hammer stroke.
Advantages and shortcomings analysis: single pneumatic hammer type is also suitable for playing a variety of piles, simple structure, short distance, equipment and pile head is not easy to break, piling speed and impact than the hammer, high efficiency. Hort type,suitable for playing a variety of piles, easy to slant pile; use of compressed air, can under underwater piling; the impact of many times, the impact of large, high efficiency, piling without piling, but the equipment bulky, moving more difficult.
3. Diesel hammer piling machine, the main body is composed of cylinder and plunger, and its working principle and single-cylinder two-stroke diesel engine similar to the use of injection into the cylinder combustion chamber of the atomized diesel fuel by high pressure after the explosion caused by a strong pressure head work.
