Construction site foundation piling machines use powerful diesel engines, are fully hydraulic-driven, capable of 360-degree rotation, lifting, and have extremely low noise during operation, minimal vibration, and are widely used. Due to the very fast drilling speed, construction efficiency is also high, and construction site foundation piling machines are gradually replacing drills by overcoming the disadvantages of electric drilling machines. At the bottom of the construction site foundation piling machine, there is a bucket drill bit with a bottom valve, rotating the bucket drill bit can break the rock and soil below, and directly fill the soil into the drill bit. How do I lower the soil? The drilling rig lifting device and telescopic drill rod unload the soil after lifting the drill bit. To reach the design depth, soil must be continuously extracted and unloaded. Of course, for different rock layers, the process we use will vary. We usually use dry water or clear water drilling technology on sticky rock layers with mud wall protection process. Although the hole formation speed of the construction site foundation piling machine is very fast, in the past, most of China's railways, highways, and some bridges used drilling cycles and impact drilling, but the results showed very low production efficiency. Using construction site foundation piling machines, therefore, the bottom of the hole has almost no sediment, and also ensures the quality of the project.

More importantly, the construction site foundation piling machines developed and produced by Shandong Hengwang Group not only ensure the cleanliness of construction sites but also reduce costs.
