深圳大运村给水设计抗高负荷冲击问题探讨

Discussion on High-load Impact Resistance in Water Supply Design of Buildings in Shenzhen Universiade Village

第26届大学生运动会的运动员村选择在深圳信息职业技术学院迁址新建的5栋高层学生宿舍,原设计每居室住3～4人,并有独立的卫生间。大运会期间,计划每居室住2～3人,给水设计需满足最多为13 000名运动员的用水需求,同时还要经受运动会开闭幕结束时的瞬间给水高负荷冲击。为此,围绕《建筑给水排水设计规范》(2009年版)出版前、出版中、出版后的不同思路的启迪,分析了分散型、密集型给水设计流量的关系,确定运动员村采用百分数法计算给水设计流量,并根据工程实际情况确定综合b值取6%,据此做出的设计经受住了大运会试验运营和实际运营的考验。

The athlete village of the 26th Universiade was five high-rise student dormitories of Shenzhen Institute of Information Technology. In the original design, each room accommodated 3 to 4 persons and had a separate bathroom. During the Universiade, each room was planned to accommodate 2 to 3 persons, and the water supply design would meet the water demands of at most 13 000 athletes, while resisting the instantaneous water supply impact load at the end of opening and closing ceremonies of the Universiade. Around the inspiration from different ideas before, during and after publication, pub- lishing, after the publication of Code for Design of Building Water Supply and Drainage （2009 revision）, the relationship of design flow between decentralized and centralized building water supply modes was an- alyzed. The water supply design flow was calculated by percentage, and the b value of 6% was deter- mined according to the actual situation. The design withstood the test of trial operation and actual opera- tion of the Universiade.
