广州科技教育城海绵城市建设工程管理实践与探讨

Practice of Sponge City Construction Project Management in Guangzhou Science and Technology Education City and Its Discussion

海绵城市建设工程管理核心是制定工程管理制度,协调多学科交叉、多部门协同,保证工程质量。总结了广州科技教育城(简称“科教城”)海绵城市工程管理经验,并对相关技术问题进行了探讨。根据“科教城”低容积率、高绿化率的自然特性,因地制宜地确定了工程建设管控重点。采用以学校景观湖体作为核心海绵设施的雨水收集、储存、处理、利用的多目标有机融合模式,建立了房建组团的工程示范模板。充分利用自然地形坡度,以校区路面作为泄洪渠道,可满足50年一遇防山洪标准。提出了优先采用复合渗透地面的做法,来解决透水面层因堵塞而逐渐失效的痛点,并建立了对不同透水铺装的量化评价方法。

The core of sponge city construction project management is to formulate a project management system,coordinate multi-disciplinary and multi-departmental collaboration,and ensure project quality.This paper summarized the sponge city construction engineering management experience of Guangzhou Science and Technology Education City(referred to as Science and Education City),and discussed the relevant technical problems.According to the natural characteristics of the low floor area ratio and high greening rate of Science and Education City,the key points of project construction management were determined according to local conditions.The project demonstration template of housing construction cluster was established by adopting the multi-objective integration mode of rainwater collection,storage,treatment and utilization with the school landscape lake as the core sponge facility.The natural terrain slope was fully utilized and the road surface of the campus was used as flood discharge channels to meet the 50-year flood prevention standard.The compound permeable surface was proposed to solve the problem of gradual failure of permeable surface due to blockage,and the quantitative evaluation method for different permeable pavement was established.
