Technical Information

Technical parameters

Representative project reference: Xiaowen Lane Foundation Pit Project in Haishu District, Ningbo. The project had a total building area of approximately 33,700 m². The retaining system used bored cast-in-situ piles, while the pit-in-pit secondary enclosure used high-pressure jet grouting piles. Passive zone soil reinforcement was carried out using high-power biaxial bidirectional cement mixing piles combined with high-pressure jet grouting piles.
The bored cast-in-situ piles had diameters of Φ600–Φ950 and lengths of approximately 19.0–36.5 m. Cement mixing piles had a diameter of Φ700@500 and lengths of approximately 2.5–16 m. High-pressure jet grouting piles were used for secondary enclosure and reinforcement works.

技术参数

代表性工程：宁波海曙区孝闻巷基坑工程。项目总建筑面积约33,700 m²，围护桩采用钻孔灌注桩，坑中坑二次围护采用高压旋喷桩，坑内被动区土体加固采用大功率双轴双向水泥搅拌桩与高压旋喷桩结合。
钻孔灌注桩桩径为Φ600–Φ950，桩长约19.0–36.5 m；水泥搅拌桩桩径为Φ700@500，桩长约2.5–16 m；高压旋喷桩用于二次围护及加固工程。
