Do you need a hydraulic piling hammer?

What is a hydraulic piling hammer? Hydraulic piling hammer is a piling machine that uses the power of the excavator, its own weight and pile weight to drive piles into the ground.

Then how does a hydraulic piling hammer work?

The working principle of the hydraulic piling hammer mainly relies on its unique hydraulic system and mechanical structure. The following are the main steps in the work of a hydraulic piling hammer:

- Lifting the hammer core: The hydraulic piling hammer first lifts the hammer core to the predetermined striking height through its internal hydraulic cylinder drive device. During this process, the power generated by the hydraulic cylinder causes the hammer core to overcome gravity and move upward.

- Energy storage: When the hammer core is lifted to a predetermined height, the hydraulic system will store energy. During this process, the pressure in the hydraulic system increases and is ready to be released to provide the impact force when the hammer core falls.

- Release the hammer core: After the energy storage is completed, the control system will release the mechanism that locks the hammer core, allowing the hammer core to fall freely. Due to the weight of the hammer core and the previously stored energy, it impacts the pile head at a high speed.

- Piling: After the hammer core impacts the pile head, the pile body is driven into the ground through the transfer of kinetic energy. During this process, the soil is compressed and consolidated, forming a stable base structure.

- Repeat cycle: The hydraulic piling hammer will continue to repeat the above steps until the pile reaches the predetermined depth and position.

What kinds of piles can use the hydraulic pile hammer?

Hydraulic piling hammers are suitable for a wide variety of pile types, including but not limited to prefabricated piles, cement round piles, cement square piles, cement sheet piles, steel sheet piles, H-shaped piles and steel pipe piles. Each of these pile types has its own characteristics and application scenarios.

For example, prefabricated reinforced concrete piles are most widely used in construction foundation projects, including industrial plants, high-rise buildings, and large bridges.

While steel pipe piles are mainly used in large factories, high-rise buildings, Infrastructure construction for deepwater terminals and offshore wind power projects is under way.

The application scenarios of steel sheet piles are very wide, covering almost all areas that require foundation engineering or temporary support, including subgrade reinforcement in road engineering, slope protection, tunnel excavation and foundation reinforcement of bridge piers. Steel frame structures such as pier foundations, river beds, lakes, and beaches in bridge projects. Reinforcement and support structures for buildings and facilities such as port terminals, shipyards, bridges, and ship-breaking platforms, and protection measures for locks, port terminals, and river channels in water conservancy projects. Slope reinforcement in tunnels and subway projects, solidification of seabed substrate and foundation construction in reclamation projects, etc.

H-shaped piles can be used in foundation support, underground excavation, bridge support and other fields in construction projects. River, lake and marine engineering. And under complex geological conditions, including soft soil areas or hard soil or rock formations.

Our hydraulic piling hammers are mainly divided into two types.

One is the S-series conventional type, where the clamp clamps the pile from the top for operation. The advantage of this type is that it has better stability and accuracy, and can drive the pile deeper.

The other type is the side clamp type. The clamp clamps the pile from the side for operation. It is more flexible and convenient. It is not limited by the length of the pile and can be constructed in height-limited spaces.

How do you know you need a excavator hydraulic pile hammer or a rotary drilling rig?

The selection of excavator hydraulic piling hammer and rotary drilling rig mainly depends on the specific needs of the project, geological conditions, construction environment, work efficiency and other factors.

Hydraulic piling hammers are suitable for use in a variety of soil conditions and perform particularly well in hard soil, rock or other difficult-to-penetrate geological formations. It can drive piles into the ground quickly and accurately through strong impact force, and is suitable for bridges, buildings, docks and other scenarios that require a large number of pile foundation projects. In addition, the hydraulic piling hammer has high construction efficiency, relatively small noise and vibration, and has less impact on the surrounding environment.

Rotary drilling rigs are more suitable for soft soil and clay strata. Their working principle is to cut and discharge the soil through rotation, thereby forming pile holes. Rotary drilling rigs can be equipped with different drill bits to adapt to different geological conditions. It has high drilling speed and accuracy, and causes less damage to the surrounding environment.

When choosing a hydraulic piling hammer or rotary drilling rig, you need to consider the following factors:

- Geological conditions: including soil type, groundwater level, rock hardness, etc. Hard soil or rock formations are better suited to a hydraulic piling hammer, while softer soil or clay formations are better suited to a rotary excavator.

- Construction environment: Consider the size of the construction site, the complexity of the terrain, and whether the surrounding environment is sensitive. Sites with limited space or complex terrain may be better suited to a rotary excavator because of its greater flexibility in movement and positioning.

- Construction efficiency: According to the requirements of the construction period and construction tasks, equipment with higher work efficiency is selected. Hydraulic piling hammers have higher construction efficiency in hard geological conditions, while rotary excavators drill faster in soft strata.

- Cost factors: comprehensively consider the purchase cost, transportation cost, maintenance cost and usage cost of the equipment. On the premise of ensuring that the project requirements are met, economical and reasonable equipment is selected.
