【正文】 he reservoir benefit not only the crash can39。不奮斗就是每天都很容易，可一年一年越來越難。 (4) construction technology is simple, less working procedure, is advantageous for the mechanized rapidly the construction. SpillwaySpillway is drainage buildings for an outlet excess floods, prevent flood accident, therefore spillway is actually a security door, spillway layout according to its position, can be divided into the riverbed spillway spillway or Banks of the river. Riverbed spillway was built using the original bed the putation of flood, it is not only the water retaining structure, and drainage structures. The spillway, set the spillway in the Banks of the river. Small reservoir dam generally for earth and rockfill dam, dam body are not allowed to flood, so many type spillway with the Banks of the river. Banks of the river type spillway can be divided by different forms of water flow into the spillway is spillway and side slot spillway trough, the spillway is trough applied most widely.Small reservoir spillway is groove is of type opening open that is monly, and most have no brake control (not set brake or candy). This kind of spillway has simple structure, convenient construction, the advantages of smooth flow, its position is: channel of flood dam (control), drain tank (steep slope section), stilling basin (energy dissipation section), tailrace, etc. Water facilitiesWater facilities is water building, is the throat reservoir project, is a leading reservoir irrigation canal system engineering, is a reservoir irrigation, water supply, power generation benefits of the key. It consists of imported valve, drain the culvert and export of energy dissipation facilities of three parts: the main function of water facilities are designed to supply water to the water unit.(1) import gate: the import of small reservoirs gate has lie tube, cylinder piston suspension rotation type and bulkhead gate several f
