In recent years, sponge cities are widely popularized by the nation as a new generation of rain flood management concept. With the continuous development of national economy and technology, the proportion of various buildings in cities is gradually increased, and a large amount of runoff formed by hard roofs of the buildings in rainfall is one of the main causes of urban waterlogging. Rainwater disconnection generally refers to the diversion of rainwater to rainwater retention facilities, such as a sunken green, rainwater garden, etc., by cutting off runoff drainage channels by some means or configuration. Rainwater entering the rainwater storage facility enters soil to supplement underground water through natural infiltration, and rainwater exceeding the storage capacity enters a site rainwater pipe network through an overflow port formed in the rainwater storage facility, so that runoff reduction and emission delay are achieved.
The common building roof rainwater disconnection design is generally to directly disconnect the stand pipe to the rainwater accumulation facility above the ground, the rainwater pipe is exposed on the ground to influence external landscape, meanwhile, if the building layer height is high, the potential energy of rainwater flowing to the ground through the rainwater pipe is too large, under the condition of no buffering energy dissipation, large impact force is formed on plants in the rainwater accumulation facility, the rainwater is easily washed away for a long time to cause the plants to grow badly and even die, the rainwater accumulation facility is not favorable for exerting the best ecological function, and the cost for replacing the rainwater accumulation facility plants is increased.
