Spring the river is containing the rich hydro-electric resources， valley section suits in the construction hydro-junction， the hydro-junction main goal is prevents floods the electricity This article unifies opens the valley terrain geology characteristic， the hydrology characteristic， has carried on the preliminary design to its hydro- The main content opens the valley hydro-junction including the spring river the basic document， the main building design， the key position scheme of arrangement， ground processing as well as the construction leads dams the current and so on the In had considered under each kind of factor， the choice second grade - second grade took this key project the dam spool thread， in the dam choice， carries on the good and bad points comparison after each kind of dam， unifies this project the local characteristic， chose the concrete entity gravity dam to take this hydro-junction the Adjusts Hong to calculate uses the quite universal semigraphical method， after has compared three accents Hong plan had determined an appropriate plan， its design flood level is 3 meters， the examination flood level 1 meters， the definite top of dam elevation is 9 This key position main building by keeps off the water building， the drainage building， the electricity generation building， blows off the building to be Passes the charging after to calculate (gravity dam is stable and stress computational procedure) and the stress and stably compares the nucleus， obtains the non- overfall dam the economical section plane， the top of dam width 5 meters， the height 9 meters; The drainage building uses the table hole overflow the way， the top of dam curve uses the practical WES curve， disappears can the way adopt selects class disappearing energy; The workshop dam section including three flow conditions and installment field sections， after the workshop uses the dam the type; Uses the deep hole achievement to blow off the building， the hole figure selects does not have presses in the dam the Finally constructs the conduction current to select two issues of two section of conduction current methods， an issue by ties the narrow river bed to release the class， two issues release the class by the conduction current bottom hole， opened the valley hydro-junction to the spring river to produce a quite complete design
The spring river contains abundant water power resources， among them， ZHANG GU3 DUAN4 suiteds for to fix to set up the water conservancy vital point， the main purpose of the water conservancy vital point is a flood control to generate This text combines a valley form geology characteristics， the hydrology characteristic， as to it's the water conservancy vital point carried on the first step The main contents includes the spring river ZHANG GU3 the basic data， main building design， vital point of the water conservancy vital point arranges the project， the foundation processing and constructions to lead to cut to flow Considered various factor under， the choice B － B conduct and actions originally the dam stalk line of the vital point engineering， choice in the dam type， to various dam type after carrying on the merit and shortcoming comparison， combine the local characteristics of this engineering， choose the concrete entity gravity dam conduct and actions originally the dam type of the water conservancy vital Adjust the 洪 calculation adoption more widespread half illustrated manual table method， at compare three adjust the project of 洪 after made sure a fit project， get it designs the flood as 3 meters， the flood a 1 meters of the school pit， make sure that a high distance of dam is 9 Main building of this vital point from block the building of water， leak water the building， generate electricity the building and put the empty building to Pass machine-readable( the gravity dam stability and should dint calculation procedure) and should to compare with pit， the dint and stabilities are after， getting to overflow the economic section of flow the dam not，5 meters of a breadth of dam， high 9 meters;Leak water the building adoption watch bore overflows the way for flow， a curve of dam adopts the practical curve of WES， eliminating the ability method to adopt to pick to flow to eliminate the ability;The factory premises dam segment includes a segment of three machines and an installs a segment， the factory premises adoption dam is behind type;Adoption deep bore conduct and actions put the empty building， the bore figure choose and use and did not press the dam inside The end construction leads to flow to choose to use two expect the two pieces to lead to flow the method， on expect from tie the narrow river bed to leak to flow， two expect from lead to flow the bottom bore to leak to flow， to the spring river ZHANG GU3 the water conservancy vital point give a the design project that compares the
