Research on Collaborative Design of Utility Tunnels and Water Supply and Drainage Systems in Xiongan New Area

摘要:

雄安新区作为国家级战略新区，其地下基础设施的高标准建设对打造绿色智慧城市标杆至关重要。聚焦于新区重点片区综合管廊与供排水管线协同设计中的关键技术难题，旨在解决传统经验式入廊决策依据不足、有限舱室内多管线排布冲突、综合管廊标准化低及多权属协同运维困难等核心问题。研究构建了融合技术-经济-运维三维度的综合评价体系，实现了给水、再生水、热力等管线入廊的量化决策。设计阶段，通过数学模型和BIM技术实现舱室断面与管线排布的精细化优化，并形成模块化、标准化技术体系。运维层面，构建了基于智慧化平台的“统一运营、专业维护”协同机制。工程应用实践表明，该体系有效缩短建设周期约33%，将给水管网漏损率降至5%以内，显著提升了城市基础设施的系统韧性与运维效率，为新建城区提供了可推广的实践范例。

Abstract:

As a national strategic new area, the high-standard construction of underground infrastructure in Xiongan New Area is crucial for building a benchmark for a green and smart city. Focusing on the key technical challenges in the collaborative design of utility tunnels and water supply and drainage pipelines in key areas of the New Area, aiming at addressing the insufficiency of traditional empirical decision-making basis for entering utility tunnel, the conflicts in the layout of multiple pipelines within limited cabin space, the low standardization of utility tunnel and the difficulties in collaborative operation and maintenance among multiple ownership units, a comprehensive evaluation system integrating three dimensions of technology, economy and operation / maintenance is studied and established to achieve the quantitative decision for the pipelines of water supply, reclaimed water and heating power into utility tunnel. During the design stage, the refined optimization of the cabin cross-section and pipeline layout is achieved through mathematical models and BIM technology, leading to the formation of a modular and standardized technology system. At the operation and maintenance level, a collaborative mechanism of “unified operation, specialized maintenance” based on an intelligent platform is established. The engineering application practice shows that this system effectively shortens the construction period by approximately 33% and reduces the water pipeline leakage rate to less than 5%, significantly enhancing the system resilience and operation/maintenance efficiency of urban infrastructure, which provides a replicable practical example for the construction of new urban areas.
