Groyne Layout For Muzhati Hydropower Station Water Diversion Impact Analysis

Because groins own characteristics,so that the river remediation process is often used as a retaining use of the building.Its main role is to protect the shore and raise the water level upstream partial guarantee upstream water diversion,while it is in improving waterways,maintaining riverbed stability and ecological protection of water resources play a significant role.The actual project,the construction of some often Groin Groin or group,to meet the requirements of water diversion channels.Because the river mouth movements and diversion channels to select different location,the construction of groins forms also differ.Thus,to explore the surrounding water Groin Groin parameters and status,to determine the arrangement of the groins,so that not only has the main hydraulics scientific value,while the groins of practical application also has practical significance.The experimental physics simulation,a typical Xinjiang river diversion system for analysis.For this water diversion project,the testing process is the main verification groin after the construction of water and sediment test trials.Experimental verification of the groins three major layout programs,all programs are aimed to ensure the water diversion channel and dam security and stability.The first scenario,due to the relatively short groins and farther away from the water inlet,backwater effect is not obvious.The second option is to improve on the basis of the first scenario,based on the groyne arranged in position only 10 m away from the intake at this time backwater effect comparison with the first program has improved,but because of the relatively groins short,there is no mainstream of the river to intercept,leading to the water near the intake affected.Water quantity can not fully meet the requirements of the power generation.Sedimentation phenomenon also exists under such programs.The third program to improve the program for the first two issues that arise,and ultimately determine the dam is 120 m long,and on the pick 30 °.At this water diversion dam safety and stability can simultaneously meet the requirements,in the vicinity of the mouth water and sediment silt dam despite appear,but compared with the previous two programs,neighborhood stability Batou has increased,the amount of water there guaranteed.Under such programs simultaneously,you can have more than the amount of water diversion system for flushing.Through this demonstration,after the river changed to some extent in favor of water,for siltation problems should build appropriate facilities in sediment diversion dam near the mouth or regular dredging.
