Q: What kind of pile driver, rotary drilling machine can drill under medium weathering rock layer?: The Xugong power head, wylong machinery mechanical lock rod rotary drilling rig Yuchai engine and can be weathered rock and sediment layer in the layer below, backfill soil drilling construction

Q: say no money, the machine is more expensive, but still busy every day do not win, do not know is true or false?: Certainly money ah, now people are selfish, just want to make money, Matlock machine good, I also encountered such a thing.

Q: How does a cement pile driver work?: That's the gravity of the object itself

Q: What are the types of pile drivers? What are the characteristics of each?: According to the hole forming process: the diesel hammer is immersed in the hole, the spiral drilling hole, and the Luoyang shovel holeIn accordance with the general classification of hole forming and compaction type: diesel hammer hole clamping hammer tamping hole; diesel hammer tamping; spiral drilling tamping (DDC); Luoyang shovel hole tamping and spiral drilling concrete pile (CFG). And what you say, pipe pile and fish, hammer, strong rammer are also belong to composite foundation. Among them, the pipe pile is divided into static pressure pile (suitable for static pressure machine into the ground) and diesel hammer pipe pile (diesel hammer directly into the ground).Several of the above are mainly to eliminate collapsibility and increase the composite bearing capacity, which belong to composite foundation. The main load of single pile is the cast-in-place concrete pile with rotary drilling holes.The above is the classification of the process, and how many layers are suitable for the construction.

Q: What is the starting current for a 55 kW pile driver? What's the big leakage switch, please?: 55KW motor, rated current of about 110A.If it is started directly, the starting current is about 450A---800A.You can choose 150A with leakage protection circuit breaker.

Q: Bridge pile driver is a stone below, how to do?: The dynamic test, if the load is small if it scored well, only the impact of iron into the stone

Q: CFG pile 22 meters deep, please tell me how many piles are required to flow out at the side of the slope. How about the 360 degree rotation of the pile driver?: General 50-80, the best drill pipe can be connected, but the construction capacity of pile driver is limited, generally there are more than 20 meters, more than thirty meters, high rack will be able to play deeper.

Q: What's the profit of a pile driver for a day at the site?: Because, after all, the pile driver is not only a few years, the choice of good quality in the early may not be cost-effective, but after taking into account, or suggest that you buy a little bit of the machine. After all, if the driver problem that you every two or three days, the work is not good for.

Q: What's the use of a pile driver?: See what you have needs for foundation piling piling machine, as well as for piling machine polishing V pile, as well as for highway guardrail guardrail installation pile piling machine, and a spiral piling machine. The foundation of the piling machine are large, the appearance looks a bit like a machine modification, it is actually the crawler chassis, and digging machine, guardrail piling machine is much also, now what are the loading type, vehicle type. There are many kinds of piling machines, such as the machines in Chengdu, what type 260, the loading type, the all-in-one, and so on.

Q: What are the parts of a pile driver?: The hammer into the exhaust valve reversing by manual control, can also be installed in the side with the hammer and hammer lifting flange lever automatic control, impact stroke two ways can adjust the hammer. Three diesel hammer body is made of cylinder and piston, similar to the working principle and the single cylinder two stroke diesel engine into the cylinder combustion under high temperature and high pressure atomized diesel combustion chamber by injection pressure generated by the detonation driven hammer working. According to the structural form of diesel hammer rod and cylinder type separation. The guide rod type diesel hammer is pressed on the pile cap with a plunger as a hammer seat, and the cylinder is used as a hammer head to move up and down along the two guide rods. When in operation, the pile hanging in place pile frame in Longmen, then put the diesel hammer at the top of the pile, the hook will lift down the cylinder, and the cylinder sleeve off hook to the whereabouts of the piston, the cylinder will be closed in the air compression cylinder rocker pin until the pressure continues to fall outside the cylinder pushing hammer on the base of the fuel pump, fuel pump will be injected into the cylinder oil mist, oil mist meet high temperature gas burning immediately above, blasting, explosive shock down pile., to push the cylinder to cylinder to rise, fall along the guide rod, and the beginning of the second impact cycle. The cylinder type diesel hammer takes the cylinder as the hammer seat and directly uses the lengthened cylinder to guide the inner wall.
