Introduction:The project includes two small designs for extreme weather in the city, namely a skybridge with water absorption function for heavy rain and a building with vacuum function for sandstorm.

The starting point of the design is that extreme weather has occurred frequently in recent years, and news of casualties and social property losses has emerged in an endless stream: 2021 Henan On July 20, 2021, a heavy rainstorm occurred in Zhengzhou, causing 292 deaths and 47 missing. The typical incident is Metro Line 5 was trapped; Beijing was hit by a strong sandstorm in March 2021, PM10 concentrations increased significantly, and visibility was less than one kilometer in most areas.

Henan Zhengzhou Line 5 7.20 Incident, the design site is the subway Shakou Road Station, the problem to be solved is the urban rainstorm and rainwater backflow, the design concept is urban sponge, and the design form comes from tree roots. In March 2021, the Mongolian plateau sandstorm event, the design site is Beijing Bell and Drum Tower Square, the problem to be solved is sandstorm, the design concept is urban vacuum cleaner, and the design form comes from pipes.

The above-ground space designed for the Zhengzhou Line 5 event is an overpass connecting the residential buildings and the entrances and exits of the two subway stations. It has functions of traffic, sky park and water storage, and the underground space has functions of water absorber and summer humidifier. The above-ground and underground spaces designed for the sandstorm event mainly focus on popular science and entertainment functions.

Two conceptual experimental designs can provide reference solutions for urban extreme weather.
