Q:How did the pile of clay work after the pile driver finished?

Classification according to the setting effect of pilesNon compaction pile: such as drilling (punching or digging) pile and bored after the first and then into the precast pile, due to removal of holes in the soil in the process of setting up, the soil around the pile is not to be excluded, and may move to the pile hole, the soil shear strength decreased, pile side friction decreases.Partially squeezed soil pile: impact bored pile, H steel pile, open steel pipe pile and open prestressed concrete pipe pile, etc.. In the process of pile setting, the soil around the pile is slightly squeezed out, but the strength and deformation of soil have little change.Pile: solid precast pile and lower pile, piles and closed cast-in-place pile in hammer and vibration during the penetration will be located at the position of pile soil mass out, the serious disturbance of the soil structure, soil strength and deformation properties influence.Classification according to the formation method of pilesDriven pile: the use of machinery will be prefabricated concrete piles, stakes, steel sheet pile into the soil layer, the soil compaction, so as to achieve the purpose of strengthening the foundation.Bored pile: the underwater concrete is used to form an end bearing pile or a friction pile, so as to reinforce the foundation.

Q:Advantages and disadvantages of pile driving methods

Here are some of the advantages and disadvantages of the above methods:Hammer method:The method is simple in construction, small in investment and convenient in construction, and has been widely used before.But there is a cut that doesn't go around. It's too noisy and doesn't work in hard soil or soft soil. It's being phased out.Static pile:Use the static pressure to press the pile into the ground, no vibration and no noise during construction. Applicable to weak soil and adjacent to the construction of structures that are afraid of vibration.But when there is a sandwich of medium thick sand with thickness greater than 2m, it is not suitable to use the static pressed pile. And there is soil squeezing effect.Vibration method:The vibration hammer is lifted to the top of the pile, pile head is connected with the vibration box pile cap or hydraulic pile clamping device for clamping, the exciting force generated by the vibration hammer pile to soil vibration, friction force between soil particles is greatly reduced, the pile under the action of self weight and mechanical force into the soil.The vibrating pile driving equipment has the advantages of simple structure, convenient operation and high efficiency. Suitable for heavy steel sheet pile, steel pipe pile and the length within the 15m slender reinforced concrete precast pile in the sand in the highest efficiency, poor little clay.

Q:How do you pile it?According to different pile, talk about some details

The diameter ranged from 300-600.Cast-in-place pile is a kind of civil engineering and construction of various types of pile foundation. It is the use of hammer piling equipment or vibratory piling equipment, with reinforced concrete pile tip (or plate boots) or with a valve type steel pipe into the soil pile shoe (steel pipe diameter and pile design should be the same size), caused by the pile hole, and then put into the steel skeleton and concrete pouring, then pull out the casing, using vibration extubation of concrete compaction, forming pile is needed.

Q:How many hours will it take for the 200 piles and the 1 pile drivers?

200 piles of 1 piling machine is generally need 19 day time is finished, also need 152 hours to complete.

Q:What is the maximum CPU of a pile driver? What about the performance of graphics will be piling machine CPU?

The official use of Bulldozer as the core code shows the unmatched performance of the CPU series.The bulldozer is the United States AMD company to re design of the CPU architecture, officially launched in October 2011, have a fever for high-end user, with DDR3-1866MHz native memory support, XOP instruction set, the modular design and a number of new features, fully replace the phenom processor of II series.

Q:How much is the hydraulic pile driver?

Between 16-40, 000. Different manufacturers. Different tonnage difference big ah, soft land dozen20 tons will be enoughI hope my answer is useful to you, if satisfied, please take ~!

Q:The pile driving team has many years of piling experience, to undertake the construction of large and small piles, includingKongguanzhu

To consider how the site can take back the unearthed excavation method is ABC pile test done to dig a long tight schedule but also increase the test equipment such as AC two AC after completion of the test sequence can also do a ramp to the middle of the excavation

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:What is the power of the pile driver?

Hello, there are many kinds of power in the pile driver. How big do you need?.

Q:The impact of drilling pile driver how much money

See how big you want to play, I want to hit a big pile on your point
