Integrated Underground Space Engineering Services

• Project planning links engineering constraints with specific construction methods and equipment rather than using a single standardized process.
• Early-stage evaluation focuses on geology, groundwater, adjacent structures, utilities, access, schedule and risk-control objectives.
• During construction, technical support can be combined with monitoring feedback, method adjustment and interface management.

Selected Applications

• Bilibili New Generation Industrial Park N5, Shanghai: The foundation pit covers approximately 19,900 m² with a perimeter of about 680 m and an excavation depth of roughly 22.1-22.9 m. Seven different construction methods were involved, requiring coordinated deployment of multiple processes within an ultra-deep excavation project.
• Fuzhou Railway Station Transfer Passage: A 109.5 m large-section rectangular pipe-jacking passage crossed composite ground near operating rail transit and major municipal utilities, requiring coordinated ground treatment, settlement control and specialized jacking operations.

• 项目策划将工程约束与具体施工工法、设备配置相结合，而非采用单一标准化流程。
• 前期评估重点考虑地质、地下水、邻近结构、地下管线、设备通行、工期及风险控制目标。
• 施工阶段可结合监测反馈开展工法调整、技术支持及施工接口管理。

代表性应用

• 上海哔哩哔哩新世代产业园 N5 地块： 基坑开挖面积约 1.99 万平方米，周长约 680 米，开挖深度约 22.1-22.9 米，属于超深基坑。施工涉及 7 种不同工艺，需要在同一项目中协调多工艺实施。
• 福州火车站换乘通道： 109.5 米大断面矩形顶管通道穿越复合地层，并邻近运营轨道交通和重要市政管线，需要统筹地基加固、沉降控制和专用顶管施工。
