Recently, heavy rainfall occurs frequently in Beijing. Rainwater pouring, slope seepage and abnormal sedimentation often happen to deep foundation pit engineering during the flood season. To effectively improve the flood control and response capacity of on-going constructions over the district, Dongcheng Housing and Urban Construction Committee organized three consecutive flood control emergency drills respectively on the construction sites of Tongzhou “2 Stations and 1 Commercial Street” Government-Subsidized Housing Units A4 Project, West Hall Project and Rongkun Pension Center Project. The drill contents include water pumping, seepage spot filling by sandbags, real-time observation of sedimentation data and medical aid. The drills examined the implementation of flood response plan of our committee and the responsiveness of dealing with accidents in construction fields. We have every reason to believe that we could do a good job in flood control and emergencies.
