Black Ditch Reservoir Dam in January 1972 to start construction,completed in 1973,the same year,canal facilities,irrigation benefit.Works mainly by the dam,spillway,drainage facilities
Composition.Dam is a homogeneous earth dam; the left bank of the spillway at the dam shoulders,for the open-free spillway gate control is; drainage facilities located across the dam at the left abutment,
Culvert for the type of shaft.Black Ditch Reservoir Dam was built in a special historical period,after 30 years of long-term operation,engineering aging and disease seriously,in July 2008
Identified through the assessment of dam safety for the three dams.The works mainly exist:lack of flood control capacity; dam downstream slope stability safety factor against sliding is less than specification requirements; dam
Body Sanjin,dam dam leakage; termites cause serious harm; spillway wall is not lined,no export of energy dissipation measures spillway; drainage culvert horizontal pipe leakage and other diseases.In accordance with the
Associated procedures,specification requirements,as reflected in major projects for disease problems,combined with bad communication Reservoir Dam reinforcement to carry out engineering design,including flood
Checking,reviewing flood control,dam / spillway / drainage facilities,remediation design and structural calculations,seepage,seismic review and so on.Were the key issues of design called
