Description

1. Technical field: [0001] The invention and the water blocking curtain at the entrance of the basement can prevent ground rainwater from pouring into the basement. 2. Background technology: [0002] At present, during the period of typhoon prevention and flood control, the measures taken to prevent rainwater backflow in the basement of the unit are mainly sandbags. When rainwater backflow occurs, a lot of manpower and sandbags need to be invested to block the rainwater from backflow into the basement. When the rain stops, some Sandbags may be damaged during transportation, and sand and stones may leak out, which will affect the environment and cause waste of resources. 3. Contents of the invention: [0003] In order to overcome the disadvantages of using sandbags for typhoon and flood control, the invention is easy to use, reduces manpower, material resources, and storage space, and is made of simple materials. It uses steel wire ropes, expansion hooks, and tension spring...
