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热心网友 时间:2024-03-22 15:38
Rotten Nian ditch reservoir in January, in 1972, in 1973, started building was completed in the same year, irrigation canal supporting benefit. The project is main by DAMS, spillway, of water facilities. The dam for homogeneous volumetric; The left shoulder, YuDaBa spillway set to open type without gate control is slot spillway; Located in left water facilities for the dam abutment shaft, through HanGuan type. Rotten Nian ditch reservoir built in special historical period, after 30 years of long-term operation, engineering serious aging, disease serious, July 2008, after the dam safety appraisal evaluation for three dam. Engineering mainly exist: flood fighting ability is insufficient; Dam downstream sliding stability of dam slope safety coefficient is less than standard requirement; Infiltration, including the abutment leakage dam; Termites drug-infested; Spillway sidewall not lining, spillway export no energy measures; Contain the water leakage of horizontal piping disease. According to relevant regulations, the requirement of the specifications, aiming at the main engineering reflects, combined with lousy Nian disease problem the engineering practice in gully reservoir reinforcement design base, including flood regulating checking and flood control review, DAMS/spillway/water facilities structure calculation, regulation design and review, seismic seepage calculation. The key problem to design the call comprehensively stated.
