Summary

Hydraulicstatic pile-pressing driver has already been widely applied in the precastpile construction of building foundation, bridge foundation,airport foundation,roadbed of railroads and trackless roads,because it can drive piles with rapid, no noise pollution ,no exhaust gaspollution and no mud pollution. Nowadays,many cities provide that it only allowed static pile-pressing driver to implement the pile foundation construction in the downtown,Hydraulicstatic pile-pressing driveris in process of replacement others traditional side-piling mechanism.

 

Since the beginning of 1990 year, the ZYB series hydraulic static pile-pressing driverwith 7 patents was succeeded in production by the Hydraulic Machine and Control Technology Research Institute of CSU which supports Changhe with its technology)。Today,ZYB series hydraulic static pile-pressing driverhas developed into the 13th generation “M” model, which can meet with the request of piling force from 80 to 1500 ton, the pile diameter is range from 300-1000mm,the square pile is range from 150-1000mm.Corresponding, the single pile loading ability reaches to 40~750 ton and is in the lead of international technology.

 

Main Performance

  1. It is the fastest pile-pressing driver in China and has a record of 1700m piling one day.

  2. It is the only pile-pressing driver in China which supporting cylinder is independent from supporting legs,consequently the supporting cylinder rod doesn’t need to endure horizontal force.

  3. It is the only pile-pressing driver in China whichdriving forces are directly transferred to the clamping jaw instead of clamping cylinder,so the service life of its clamping cylinder is increased more than several times .

  4.  It is the only pile-pressing driver in China which makes pile keep automatically parallel  with guiding rail and which four guiding rails are welded as a body in order to keep the four guiding rails parallel forever.

  5. It is the only pile-pressing driver in China which uses big oil-sucking-up pipe for oil sucking up and oil cooling.

  6. It is the only pile-pressing driver in China which uses alloy steel in body for large tonnage machine.

  7. It is the only pile-pressing driver in China which has a patent of accelerated pile-driving system .

  8. Optimal structure design according to theory of fatigue strength ensures the fatigue life longer than 15 years.

  9. Compared with other hydraulic static pile-pressing driver in China,the contact area between clamping jaw and pile increases over 1 time,The jaw-clamping pressure drop over 50% which can prevent pile from being damaged by clamping jaw for too much jaw-clamping pressure .

  10.  Compared with other hydraulic static pile-pressing driver in China,Changhe has reasonable special design of the clamping and pile-driving cylinder. Clamping cylinder effective working area is increased over 20% which ensures pile clamping reliable.

  11. Counterweight beam is on the outer side of the supporting leg cylinder,compared with counterweight beam inside of the supporting leg cylinder, the place for counterweight increase 40% and the max force born by body reduce 20%.

  12. ZYB series hydraulic static pile-pressing driver using pressure compensation type automatic variable pump  realizes constant power output, so there no working overflow power loss

  13. Special hydraulic pipeline and cooling system makes pile-pressing driver can work normally in any temperature.

  14. The close oil injecting and filtrating system makes oil injecting and filtering very convenient and be free from pollution.

  15. Compared with other hydraulic static pile-pressing driver in China,its rotary platform is about one meter longer,this can increase the steady of machine when the short-feet support the body.

  16. The structure of net-shaped rib in long feet and short feet guarantee that there are at least two rib in feet confront the pile head when feet stepped on Φ400 pile head ,the penetration-resisting ability is improved by about 40%.

  17. the crane of pile-pressing driver can hoist its long feet and short feet.

  18. Compared with others side piling mechanism, ZYB’s side piling system and body is a whole,this structure arises its strength and rigidity by 30%~50%

  19. Compared with other hydraulic static pile-pressing driver in China, the distance between ZYB’s side piling center and the nearest supporting leg reduces  by at least 50%。Under the same counterweight condition,ZYB side pile driving ability raises by at least 20%.

  20. Oil pump station is positioned within working range of crane. Compare with the oil pumps station positioned under operation cabin,the maintaining service time for oil pump station is reduce 80%

  21. Compared with bifid ball head gland and connection by bolt and tapped hole in ball head base used in other hydraulic static pile-pressing driver in China,ZYB use integral ball head gland and connection by bolt and nut。Firstly,it can avoid ball head jump from the ball head gland;Secondly,it can avoid  the damage of ball head’s tapped hole in ball head base, it needs spend 300 times cost to replace ball head base.

  22. compared with the whole Walking trolley with the axles and trolley carrier welded as a whole used in other hydraulic static pile-pressing driver in China,ZYB’s axles is movable from trolley carrier. If the axles is damaged,it need to only replace axles,rather than to spend 10 times cost to replace the whole trolley.

  23. Compared with others hydraulic static pile-pressing driver in China, 680 model and 800 model of ZYB’s pile-pressing driver is equipped 20 ton crane,the capacity of crane increase by 20%.

     

Patented Technology

1. The patented pile-clamping mechanism with function of clamping jaw automatic aligning and swing, make the position of clamping jaw adapt to different size and position of piles by itself, minimize damage to the piles. The pile-driving force is directly transfer to clamping jaw from the clamping box, in order to keep the pile clamping cylinder from being damaged by the pile-driving force.

    

2. The patented long-feet-moving mechanism directly driven by double carts prevents the lifting mechanism from easily being damaged by enduring double horizontal force.

 

 3. The patented cantilever articulatingmechanism has the rigidity and strength 30% higher than traditional plug-in cantilever, making the machine more stable to operate and more convenient to transport.

 

4. The patented lifting mechanism with protective sleeve(machine above 420t) or upside down(machine below 360t) prevents piston-rods of cylinders from enduring horizontal forces and consequently brings them longer operating life.

 

5. The patented multi-grad control of pile driving velocity doubles the piling speed..

 

6. The patented auto-replacement mechanism of traverse and rotary motion automatically keeps the rails of the short feet being parallel all the time and protects the machine from being damaged.

7. The patented pile-clamping mechanism with clamping cylinder axial driving and replacement of radial spring, makes 8 clamping jaw structure come true and more reliable. Every two basic tubular jaws drive one square jaw with a replacement of radial spring, aiming at clamping the square pile. The pile-driving force is directly transfer to clamping jaw from the clamping box, in order to keep the pile clamping cylinder from being damaged by the pile-driving force.

Q:What are the characteristics of hydraulic static piling compared with traditional pile driver?
The pile is pressed by its own weight. Besides the weight of the pile, the weight of the pile should be installed with a total weight of more than 600 tons to the thousand tons.There is a large power hydraulic pump station with maximum power of more than 300 kW at run time.The pressure prefabricated pipe pile is clamped by hydraulic cylinder and pressed down by segment. The noise and vibration are smaller, and the bearing capacity can be known.Pile with hook.
Q:Where do I learn to build a pile driver?
Test piling permit can be trained by way of evidence, I have worked over these special operations personnel, piling a lot of points, see you want to learn that, 1. diesel hammer pile, 2. static pressure pile,.3 punching pile, 4. rotary pile,.5 drilling brick, and so on.
Q:What does "driving pile" mean based on dynamic compaction?
The dynamic compaction method can improve the strength of the foundation soil, reduce the compressibility, collapsibility and improve the ability of anti liquefaction and elimination of soil, suitable for processing the gravel soil, sand, silt, clay, and miscellaneous fill soil foundation, is often used for treatment of liquefiable sand soil and collapsible loess the foundation.
Q:Is this machine a pile driver?
A static pile driver that presses the cylinder into the ground with the machine! Foundation reinforcement!
Q:How to safely operate a pile driver?
Code of practice for safety operation of pile drivers(1) all kinds of pile operators should be trained and tested, and obtain special operation personnel operation certificate, with operation permit operation.(2) the pile shall be vertical and the pile forward shall not exceed 5 degrees, and the back shall not exceed 18 degrees.(3) the angle between the steel wire rope and the guide rod shall not be greater than 30 degrees, and the lifting stake shall be operated according to the operation rules of the lifting operation. It is strictly prohibited to tilt or tilt when lifting precast piles.(4) the hammer of the wire rope should be slightly relaxed after instrumentation, to prevent the hammer lay wire rope, tug, hammer head hook should be locked.(5) diesel hammer pile machine, hoist hammer, hanging pile must use the winch ratchet insurance. Start piling hammer should be opened before the mechanical lock, the hammer claw retracts, starting out before starting the hook, prevent the hammer hanging from the pile top pile accident.
Q:Piling of percussive drilling
7, the drilling process control should be rigorous, but also do not have to worry about failure, a reasonable choice of treatment methods, generally can be solved, the common, foot blade perforation, hole collapse, partial hole, cross hole, drilling, drilling, drilling buried crane, well preventive measures are generally not in advance, very important duty responsibility. 8, the remaining holes, steel cage decentralization, concrete pouring, sealing and other are more conventional, do not write more. But the bottom of the hole, sediment, sediment, etc. must be recycled clean, otherwise it will be buried in the later works of greater risk. When the concrete is poured, the bottom concrete under the impact of residue inclusion in steel or bond caused by defects in the pile in concrete, on the upper structure of the load transfer to the bottom of the pile, the structure will definitely should produce uneven settlement for residue.
Q:Why do some people need to dig the foundation and pile it up to dig a hole?
how to do?You say the digging and then piling, probably because the pile is the need for technology, such as filling piles, you do not dig, you can not do, or that you have obstacles on the surface, to dig into the original soil piling, so good control piling quality
Q:Pile driver, pile, cylinder, oil seal installed, there is no positive and negative
Yes, no, you can take pictures before changing the seal, then change the seal.
Q:Is there a pile driver in it?
However, the piling machine is not stable, but also a team together. And we're going out of town, this month, ten days.
Q:I can drive an excavator and a hammer, but I want to learn how to drive a pile driver. How long will it take to learn?
Look at yourself, you work hard, not hard, notAskHow long can you learn?Chasing the answerLonger, it is harder to hit the column than the excavator and the crusherNo, very soon
