【文章內(nèi)容簡介】 s dam, etc. My county on small reservoirs are earth and rockfill dam is a kind of local material dam, which is posed of earth, stone, or the generation by rolling into a water retaining structure, the dam type is widely used in water conservancy project. In our county, 140 small reservoirs, all for earthrock DAMS. At present this kind of dam type is the main reason of the wide scope of application: (1) dam materials can use local materials。 (2) is able to adapt to the foundation deformation。 (3) simple structure, reliable operation, easy to maintenance heightening or expanding。 (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
