With the evolution of the times, the era of traditional piling has laid the foundation. Currently, even residential buildings are typically two-story structures, which has quietly heated up the market for diesel foundation pile drivers. Where the pile depth of the original plain pile drivers was about 10 meters, the current small rotary drilling rigs reach depths close to 30 meters. When many customers purchase pile drivers for house foundations, they are confused about whether they are buying a pile driver or a small rotary drilling rig. Hengwang Group spends tens of thousands of yuan, but purchasing a small rotary drilling rig is still cost-effective. For project construction, the pile depth can easily reach about 20 meters. If you opt for a small pile driver, you will be surprised at the basic structure of high-rise buildings. Diesel foundation pile drivers include small wheeled rotary excavation drills or small crawler-type rotary excavation drills.
