为改善水库防淤营运功能，以加速水库治理及维持水库营运寿命，将台湾南部之曾文水库永久河道放水道控制闸门由何本阀（Howell-Bunger valve）更换为射流闸门，除新设3条隧道分别提供施工维护及通气需求外，配合射流闸门闸室空间需求，将原何本阀闸室往上方扩建，并设置双轨电动吊车，解决何本阀因排砂磨损与空气量不足及后续设备维修更新运输等问题，于台洪期间优先开启射流闸门之设施，排除异重流或浑水潭高浓度泥砂，减少水库淤积与提高水库排砂效益，以提升水库营运操作之安全。

For improving reservoir desilting operating functions to accelerate reservoir management and the maintained reservoir operating life,so that using jet flow gate to replace existing Howell-Bunger valve in Tsengwen Reservoir Perma-nent River Outlet (T.R.P.R.O.)at southern of Taiwan.Except building three new article tunnels respectively pro-vides construction maintenance and the ventilation needs outside,tie Jet gate room space needs,the original valve gate room will expansion upwards,and set double-track wire rope hoists to settlement what Howell-Bunger valve due to row sand wear and air volume insufficient,and the follow-up equipment maintenance update and transport problem.To en-hance reservoir operation safety,it will priority open jet flow gate facility during typhoon and flood period,excluding density current or muddy lake high concentrations of silt and reduce siltation and improve the efficiency of reservoir desil-ting.
