摘　　要：琴台美术馆外形独特,需要在屋面形成“梯田”流淌的奇妙景观,因此导致屋面汇水分区繁杂。屋面雨水的径流组织和排放需要与其造型紧密契合,除了最大限度地减少采用雨水系统管道快速外排外,还需要结合海绵城市建设目标要求,优化屋顶海绵设施选型,减少快排的雨水径流总量。为了确保屋面雨水排放安全,防止美术馆藏品在储藏、陈列过程中受到水渍影响,在兼顾室内空间布置丰富多样的条件下,采用北侧大屋面导水沟集中汇水、设置虹吸雨水沉箱排水,南侧大屋面导水沟分区汇水、重力自流排水,实现了屋面雨水排水的生态与安全完美组合。The unique shape of Qintai art gallery requires the wonderful landscape of"Terraced fields"flowing on the roof,which leads to the complicated roof catchment areas.The runoff organization and discharge of roof rainwater need to be in close agreement with its shape.In addition to minimizing the use of rainwater system pipes for rapid external discharge,it also needs to be com-bined with the requirements of sponge construction objectives,optimizing the selection of roof sponge facilities to reduce the total amount of rainwater runoff.In order to ensure the safety of roof rainwater discharge,to prevent the collection of art gallery from being affected by water stains in the course of storage and display,and taking into account the conditions of rich and varied indoor space layout,the large roof on the north side adopts the centralized catchment of the gully and sets the siphon rainwater caisson to drain,while the large roof on the south side adopts the catchment of the gully and gravity to drain,the ecological and safe combination of roof rainwater drainage is realized.
