Commonly used piling machinery has the following types: The mechanical hand can pull the pile, the noise and vibration are large, the vibration hammer can pull the steel pile, the noise and vibration are large, the static pressure pile driver can low noise, low vibration, and the pile can be pulled, which can only be applied to the characteristics of all kinds of pile driving methods in the linear section.

Commonly used piling machinery has the following types:

The mechanical hand can pull the pile, the noise and vibration are large, the vibration hammer can pull the steel pile, the noise and vibration are large, the static pressure pile driver can low noise, low vibration, and the pile can be pulled, which can only be applied to the characteristics of all kinds of pile driving methods in the linear section.

At present, steel sheet piles are driven by vibration method and static pressure method, and the vibration hammer is divided into two kinds, one is the vibration hammer installed on the excavator, that is, the manipulator, the manipulator can move the steel sheet piles by itself, without the assistance of the crane; The other vibratory hammer is assisted by a crawler crane. Static pile machine is a new technology, developed by Japan, widely used in foreign countries, because of its high construction costs, it is not widely used in China, but it has many advantages: low vibration, low noise, high precision, small operation surface. The static pile press is generally driven by hydraulic pressure, and the reaction force is obtained from one or more sheets of steel piles that were previously sunk.

Auxiliary construction method According to relevant engineering experience, the efficiency of steel sheet pile sinking in the soil layer with the foundation bearing capacity ≥150KPa is low, and it is easy to damage the pile, so auxiliary construction methods such as: water flushing method, pre-drilling method, and blasting method are needed. Water flushing method is conducive to pile sinking by setting jet port at the bottom of the pile and loosening the soil by jet, but a large amount of water may cause side effects, which should be paid attention to in use. Pre-drilling method Reducing the resistance of soil mass is beneficial to pile sinking, but the aperture should be controlled. The blasting method first puts the explosive into the drill hole and then covers the soil to ignite, forming a V-shaped trench, which is rarely used in practice.

Steel sheet pile is a widely used supporting material, with energy-saving, efficient, environmental protection, green and other characteristics, Larsen steel sheet pile suppliers, mainly reflected in the steel sheet pile high strength, light weight, good waterproof performance; Strong durability, long service life; Strong interchangeability, reusable; The environmental protection effect is remarkable, in the construction can greatly reduce the amount of soil and the use of concrete, pull larsen steel sheet pile, effectively protect the land resources; It has a strong function of disaster relief, especially in flood control, collapse, collapse, sand flow rescue and disaster relief, the effect is particularly fast; The construction is simple, the construction period is shortened, and the construction cost is less. Safe and reliable. It is its unique function that is favored by the market. Larsen steel sheet pile has good water retention and can cope with the general situation. And the traditional water curtain is poured with concrete, not suitable for steel sheet pile. In addition, if it is not possible, you can coat the expansion ji at the lock, so far there is no big project example in the onshore trough steel sheet pile sealing, there are foreign countries, Larsen steel sheet pile rental price, the domestic only stays in the theoretical stage.
