Abstract: One of the major objectives of the reservoir project is to provide domestic and industrial water for Shiqiao Town, Zhawang Town and Zhawang Lingang industrial area of Ganyu County as well as considering the regional flood control and the farmland irrigation. The reservoir is in the water related environment for a long time, subjecting to the action of highwater head, the dam body is seriously damaged. It is of great significance to understand the seepage state inside the dam structure. Therefore, it is particularly important to monitor the seepage stability of reservoir by using the pressure measuring pipe. The pressure measuring pipe is an old and common seepage monitoring instrument, which depends on the height of the water column in the pipe to indicate the magnitude of the osmotic pressure. It can be used to monitor the seepage line, osmotic pressure, groundwater level and the seepage around the dam. This instrument is widely used in the water conservancy, petroleum, chemical industry, construction machinery manufacturing, coal mining and other industries. This paper describes the buried and sensitivity test of the pressure measuring pipe, observes the water level of the pressure measuring pipe, and judges the safety of the reservoir by analyzing the wetting line.
