The Pre-bored precast concrete pile technology is to solve the shortcomings of existing precast pile construction, such as the difficulty of squeezing the soil and penetrating the interlayer, and improve the compressive, uplift and horizontal bearing capacity of the precast pile in the soft soil foundation, combined with the bored pile With the advantages of precast piles, a non-squeezing soil implanted high-bearing precast pile construction technology was developed.

Ningbo Zhongchun Hi-Tech Co., Ltd. (hereinafter referred to as "Zhongchun Hi-Tech") was founded in 1984. For more than 30 years, we have been loyal to our original intentions, focusing on the research and development and production of cement products, committed to providing high-quality integrated solutions for cement products for modern urban construction, and creating a green, safe and beautiful life foundation for people. Zhongchun Hi-Tech's business scope covers precast piles, subway segments and other fields. It has five production bases in Shanghai, Yuyao, Ningbo, Taizhou and Wenzhou, ranking third in the domestic precast pile industry.

At the 2020 China Concrete Exhibition, Zhongchun Hi-tech demonstrated the Pre-bored precast concrete pile technology. The Pre-bored precast concrete pile uses a low-noise drilling machine to form holes (Pre-bored) and embedding method to complete the pile foundation technology of prefabricated piles (pile planting). The master of modern pile foundation technology.
