diversion dam
1.This paper presents with stress the application of reinforced concrete with steel fibre meshes( FOC) to hysraulic structures including aqueduct, gate, small diversion dam and light quay wall, calculation of strength of nomal and diagonal sections of T-beam and also calculation of bearing capacity of sheet.
5.The construction scheme is briefly introduced herein, and furthermore, the diversion structures, the composite scheme consisting of open caisson group adopted to treat the overburden of the foundation for the Stage 2 longitudinal concrete cofferdam and the diversion method of bottom outlet combined with the dam gap used for the Stage 2 diversion are described as well.
7.In this layout,the water-retaining and water-releasing structure i.e.the concrete arch dam,is arranged on the river bed,and the underground power house on the left bank and the water diversion tunnel on the right bank. The artificial aggregate system and the high concrete mixing system are arranged at the gentle Dingjia col on the right bank,downstream form the dam.
10.Abstract: Navigation and hydropower project at Feng Dongzi in Qujiang River is a comprehensive utilization hydro-junction of navigation combining with water power.Water intake for hydro-power station is located at the unfavorable convex bank in the bending river.In connection with the results of model test,this paper studies the different moving characteristics of water and silt in the reach of dam region before and after the project is built.The reasonableness of plane layout for water intake and fail-water channel is shown,and the influence on sand prevention during water diversion for reservoir sedimentation is discussed.It is put forward to project measures of improving conditions of sand prevention during water diversion for hydroplant intake,and synthetic system of sand prevention for intercepting sand,leading sand,and draining sand is adopted.Better effects for sediment control are gained.The recommended schemes have been adopted by design department.
