城市商业、公寓、酒店项目更新改造给排水设计

Water Supply and Drainage Design for Renovation of Urban Commercial, Apartment and Hotel Projects

针对城市更新改造中的商业升级改造、高端公寓改造、星级酒店改造项目的特点,有针对性地提出改造建议。对于地库连通扩建改造项目,充分考虑开挖对重力雨污水排水管道坡度的影响,提供多个路由重新规划、安装提升装置等方案建议。考虑到公寓生活热水改造热水循环的特殊性,利用支管电伴热技术,不但解决了大户型支管循环热水机械水表计量误差问题,而且显著改善了节能节水和使用效果。借鉴国外养老社区生活热水防烫伤要求,在高端养老项目中设置恒温混水阀,并针对噪声高标准要求和可利用机房面积有限的实际情况,采用管网叠压式供水满足日后使用需求。

In view of the characteristics of commercial upgrading and renovation,luxury apartment renovation and star‑rated hotel renovation projects in urban renewal and renovation,some suggestions according to local conditions are put forward.For basement connectivity expansion project,the impact of excavation on stormwater and sewage gravity drainage pipe is fully considered,and routes re‑schedule and lifting device setup are suggested.For domestic hot water recycling retrofit in apartment,the electric heat tracing of branch pipe not only solves the mechanical water meter tolerance issue,but also improves the energy saving and use effect significantly.According to global anti‑scalding requirement in continuing care retirement community,the thermostatic mixing valves are set in luxury retirement community project.In view of the high living noise control standard and the limited available room area,water supply devices with superimposing pipe pressure is adopted to meet the water consumption requirement.
