Problems solved by technology

[0003] Since piezometers are mostly drop-in type, after long-term work, some instruments may not be able to be used normally due to insulation degradation, and what is more, they will be scrapped directly due to leakage.

Embodiment Construction

[0017] The design will be further described below in conjunction with the accompanying drawings.

[0018] like figure 1 As shown, the chord piezometer package of the present invention is first subjected to core mounting. The core body includes a pressure sensing element 1, a steel string 3, a main body 4, an excitation coil 5, an upper end 6 and a cable 8; specifically, the following steps are included:

[0019] 11) Take out all the parts of the string piezometer, clean the parts, remove the surface oil, and dry them;

[0020] 12) Check the steel string 3 and confirm that there is no defect, and check the insulation of the cable 8;

[0021] 13) Connect one end of the steel string (3) to the pressure sensing element (1) through the insert (7); pass the other end of the steel string (3) through the main body (4);

[0022] 14) The main body is generally a cylinder, and two circular holes are arranged on the side of the main body at 180 degrees relative to each other. Place the...

Abstract

The invention discloses a vibrating wire piezometer encapsulating method. The method comprises the steps of (1) installing a core body of a vibrating wire piezometer, (2) conducting glue injection encapsulation on the core body, (3) conducting pressure testing on encapsulated assembly parts, and (4) installing shell parts. The method facilitates the maintenance of the instrument, enables problems to be found out conveniently, and enables the quality of the instrument to be improved.

Description

technical field [0001] The design relates to a string-type piezometer packaging method, which belongs to the technical field of water conservancy, and in particular relates to the technology for monitoring seepage water pressure of geotechnical engineering and other concrete buildings. Background technique [0002] The vibrating wire piezometer is used to monitor the seepage water pressure of geotechnical engineering and other concrete buildings. It is suitable for long-term buried in hydraulic buildings or other buildings and their foundations, or installed in piezometer tubes to measure structures Internal and foundation seepage water pressure, and at the same time measure the temperature of the buried point. It can also be used to measure the water level of the reservoir or the groundwater level of the slope. [0003] Since piezometers are mostly drop-in type, after long-term work, some instruments may not be able to be used normally due to insulation degradation, and wh...
