My county most of reservoir adopts screw drum hoist plate gate crane flat, reservoir management in particular, familiar with and keep import valve drawings and relevant technical data, to utilize the normal operation and maintenance.(2) water culvert: small reservoirs of water culvert is usually called 剅 tube, because buried under the dam foundation, in the earth dam and dam under the culvert (hole). Its role is: to meet the needs of the department of water, to supply water to the water downstream of the reservoir, also can assist flood when necessary. The basic requirement is to use flexible, safe and reliable and dam body is good. The characteristics of the reservoir Of the reservoir water level and capacityCapacity of the reservoir water level and is a symbol of working condition of the reservoir39。 Pesticides。 Dam 1 Basic knowledge of the reservoir1 .1Reservoir and the main building Reservoir flood control standardAccording to the ministry of water resources, the department of energy39。s two main characteristic level reflects the degree of reservoir filling up with rain, generally expressed in altitude, the unit is meters, meters, such as water level, said with average sea level as a datum, Qingdao yellow sea water meters on the datum plane, also known as the yellow sea refers to when a water reservoir can water storage volume size (volume), usually with cubic water level and capacity of the unit is different, but the corresponding relationship between them have each other, a reservoir water level is corresponding to a corresponding capacity. General said the reservoir characteristics of water level and capacity. Water area of curveAs the change of water level, the surface area of the reservoir is also different, different water for different surface area. Water level, the corresponding relationship between the size of the available curve, called water
