Product Description

Product Description

 

operating principle

Hydraulic impact pile hammer: It completes the pile driving work of pile foundations by utilizing the impact force of high-pressure oil. The hydraulic oil is pressurized by a hydraulic pump and then transported to the hydraulic cylinder of the hammer head. The piston is pushed to drive the hammer head to quickly rise to a certain height, and then suddenly released. Under the action of gravity and the pressure of hydraulic oil, the hammer head accelerates and falls, generating a huge impact force on the top of the pile and gradually driving the pile into the ground.

Hydraulic vibratory pile hammer: The pile body is gradually pushed into the foundation through vibration force. It is equipped with an eccentric shaft or eccentric block inside. Driven by a hydraulic motor to rotate at high speed, it generates high-frequency vibration. The vibration is transmitted to the pile body, causing changes in the soil structure around the pile, reducing the strength. The soil around the pile body is liquefied, reducing the frictional resistance between the pile side and the soil. Then, combined with the downward pressure of the excavator, the vibration sinking and pulling hammer and the self-weight of the pile body, the pile is sunk into the soil.

Hydraulic static pile hammer: It uses high-pressure oil to push the pile body and complete the pile sinking work of the pile foundation by static force. Relying on the stable pressure provided by the hydraulic system, the pile is slowly pressed into the ground. It is suitable for some special working conditions with high requirements for vibration and noise in the surrounding environment.

Types and applicable geological environments

Conventional hydraulic pile hammer: It has a large amplitude and is suitable for construction in cohesive soil. In cohesive soil, a larger amplitude can better overcome the resistance of the soil and allow the pile body to sink smoothly.

High-frequency pile hammer: Suitable for sandy soil. High-frequency vibration can rearrange sandy soil particles and reduce the friction of the soil on the pile, facilitating the driving of the pile.

Non-resonance pile hammer: Usually also a high-frequency type. It is suitable for areas with strict restrictions on vibration, such as urban centers, near hospitals, schools, etc. When constructing in these places, the non-resonance pile hammer can effectively reduce the impact on surrounding buildings and the environment.

application area

Basic engineering construction: In the foundation engineering of buildings such as houses and bridges, it is often used to drive pile foundations to provide stable foundation support for buildings.

Oil field and port engineering: In oil field and port construction, it is used for piling and fixing of pile foundations to ensure the stability of facilities such as oil well platforms and docks.

Bridge construction: It plays a key role in bridge construction and is used for the foundation support of piers and abutments to ensure the structural safety of bridges.

Municipal engineering: It can be used for basic construction of municipal projects such as urban roads, drainage pipelines, and underground comprehensive pipe galleries. For example, steel sheet piles and steel pipe piles are driven for foundation pit support.

 

Our Advantages

 

Good environmental protection performance: Compared with traditional pile hammers such as diesel hammers, hydraulic pile hammers have low noise, no pollution, and low vibration. They meet modern environmental protection requirements and are especially suitable for use in areas with high environmental requirements such as urban construction.

Excellent dynamic characteristics: It has high striking energy and precise striking control. It can accurately adjust the striking force and frequency according to different pile types and geological conditions to ensure the quality and efficiency of pile driving.

Strong controllability: Through the control of the hydraulic system, actions such as the ascent, descent, and stop of the pile driving hammer can be conveniently realized. Moreover, the striking energy and frequency can be precisely adjusted to adapt to various complex construction conditions. Douyin Encyclopedia.

High energy transfer efficiency: The energy transfer efficiency of hydraulic pile hammers can reach 70% to 95%. Compared with other types of pile hammers, it has less energy loss and can transfer power to the pile body more effectively, improving pile driving efficiency.

Wide range of applications: It can drive or pull piles of various materials and shapes, such as steel piles, cement piles, rail piles, iron plates, H-shaped plates, drainage pipes, etc., and is suitable for various geological conditions and construction environments.
