Embodiment 1
[0020] Please refer to Figure 1-2 , The flood control facilities used include setting up a pump 1, constructing a ditch 2 and a closed pipeline 3 connected to the pump 1 and ditch 2, constructing a flood control dyke 4, installing a water level monitoring device 5 on the flood control dam 4, and setting up a water level monitoring device The alarm device 6 matched with the device 5, and the controller 7 connected to the pump 1; for the prevention and control of waterlogging in mountainous or basin cities: For mountain water sources confluenced from the surrounding mountains in mountainous areas or basins or other forms of urban waterlogging, Scientifically construct multiple ditches 2 on the mountainside, and use the siphon principle to guide the mountain water to the drainage system in the urban area or downstream of the urban area through the ditch 2 and closed pipeline 3. At the same time, choose suitable places to build flood control dams 4 to block the floods from entering ...
Embodiment 2
[0022] Please refer to Figure 1-3 , The flood control facilities used include setting up a pump 1, constructing a ditch 2 and a closed pipeline 3 connected to the pump 1 and ditch 2, constructing a flood control dyke 4, installing a water level monitoring device 5 on the flood control dam 4, and setting up a water level monitoring device The alarm device 6 matched with the device 5, and the controller 7 connected to the pump 1; for the prevention of waterlogging in plain cities: first build permanent reinforced concrete flood control dams 4 around the city. For the precipitation water source in the city, pass The precipitation of buildings can account for at least 30% of the precipitation in the urban area. It can be directly discharged to the outside of the urban flood control embankment 4 or downstream of the urban area through the closed pipeline 3. For the water source that directly falls to the ground without passing through the building, according to the topography: Set ...
