A Calculation Method for Flood Control and Drainage of Lake and River Sluice Pump System in Plain Lake Area

Abstract

The invention discloses a calculation method for flood control and drainage of a lake and river sluice pump system in a plain lake area. Process; use the basic equation of unsteady flow in open channels with lateral inflow to calculate the lower water level of the first sluice, the upper water level of the last sluice, the water level in front of the pumping station, and the water level of the river channel measuring point in the two-stage series sluice group; establish different flow regimes of the sluices The gate outflow model below is used to calculate the discharge capacity of the sluice; the flow calculation model of the flood diversion area is established to calculate the flood diversion flow; the drainage model of the pumping station is established to calculate the drainage capacity of the pumping station. The invention can effectively solve the model of the state result of the flood control and drainage system from the known conditions and specify the scheduling strategy; and propose the operation opinions of large-scale drainage pumping station scheduling and main lake control according to the computer simulation results of the flood control and drainage system state.

Description

Technical field [0001] The present invention relates to the technical field of water resources and the environment, particularly, to a lake area Lake Sluice Flood Control Routing Method pump system. Background technique [0002] Department of rivers and lakes in South my country Lake alluvial plain, flat terrain, fertile land, abundant rainfall, dense river network, numerous lakes, is an important agricultural and sideline production base. However, due mostly below ground elevation outside Hong Jiang water level, flood protection dyke security depends. Concentrated rainfall and flood, flood Lakes by sustained high water levels outside the river backwater, difficulty gravity drainage, easy to form collapse flood disasters. After treatment, most of the lake has formed Lake River Regulating District (including flood storage lakes and equipment storage area, etc.), drainage, drainage sluices and pumping stations (including Pumping Station and within Pumping Station) and other works c...

Problems solved by technology

So far, most domestic and foreign studies on the optimal scheduling of flood control systems in plain lake areas and urban river and lake sluice pump group drainage systems have focused on construction planning or project demonstration. For the optimization of large drainage systems composed of flood control and drainage facilities in plain lake areas Few studies have been done on drainage scheduling and operation
