【Abstract】There are frequent disasters in the downtown of Tianjin. It is proposed to use engineering and non-engineering methods to mitigate urban shackles. As for engineering measures, we should accelerate the construction of “sponge city” and “ecological rehabilitation and patchwork urbanism” to transform the open space from small, medium, and large scale, build urban water storage and seepage space to contain the drainage from the source, and slow down urban runoff. We should construct a perfect drainage pipe network and delimit reasonable drainage zones, improve urban drainage standards and set up one-way drainage outlets, build river gates and drainage pumping stations, and achieve rapid drainage during heavy rainfall. With respect to non-engineering measures, we should use big data and Internet technologies to build urban waterlogging prediction and service platforms, increase the forecast level of urban water accumulation points and the level of public participation, and realize the participation of all people in the city during heavy rainfall. The management also quickly controls the inflowing water points. Finally, we should rely on the construction of smart cities, strengthen the construction of a comprehensive disaster prevention platform and construct an emergency disaster prevention platform in the city by the intelligent control of various drainage facilities and departments. At the same time, we should enhance the exchange of data among different departments and draft the emergency strategies timely. In these ways, we can finally mitigate the waterlogging in the city.
