Obtaining architectural technical performance certification from a third-party organization! Method using square precast concrete column piles.
The "Q Pile (SRP Method / SRP Raft Method)" is a ground reinforcement method that utilizes square precast RC column materials as ground reinforcement materials. Due to the simple shape of the square precast RC column materials, manufacturing costs are low, and everything is compact, making handling easy, which results in overall low costs. By simply installing them, the bearing capacity at the head can be easily measured, and the bearing capacity of all piles installed on-site can be determined. The small-diameter piles are installed using a press-in method, resulting in low noise and low vibration. 【Features】 ○ Reliability → Obtained building technology performance certification from a third-party organization ○ Space-saving → Materials are delivered by small trucks (2t to 4t), and the delivery vehicle quickly transforms into construction machinery ○ High quality → Achieved high quality through thorough inspection ○ Installation using a dedicated driving machine or a truck-mounted pile driver For more details, please contact us or download the catalog.
