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 organ-ization 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.
