Problems solved by technology

[0002] The existence of water has an important impact on geotechnical engineering. In geotechnical engineering, in order to prevent natural disasters such as landslides and ensure the safety of the dam, it is necessary to measure the water level and seepage data of the groundwater level, reservoir water level, and dam infiltration line. , the conventional piezometer is buried at the bottom of the borehole. The piezometer is buried at the bottom of the hole for a long time and is easy to be damaged. The borehole is sealed with cement, so it is inconvenient to repair and replace the piezometer.

Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings.

[0025] An osmometer for easy replacement of sensors, the structure of which is as follows figure 1 As shown, it includes: a water pipe 2; one end of the water pipe 2 is flexibly connected with the airtight casing 5, a sensor 6 is arranged in the airtight casing 5, a water permeable part 1 is arranged at the other end of the water pipe 2, and the airtight casing 6 The other end is provided with a water injection hole 7, and the water injection hole 7 is closed by the sealing cover 9, so that the sealed housing 5 becomes an internally sealed environment, preventing the water inside the sealed housing 5 from flowing out, so as to ensure that the sensor 6 is sealed in a saturated state When working, the sensor 6 communicates with the outside world through the cable 8, and outputs the signal.

[0026] The airtight casing 5 is provided with a protective casing 3 outside, wh...

Abstract

The invention relates to an osmometer and method convenient for sensor replacement. The osmometer comprises a water pipe, one end of the water pipe is movably connected with a sealed casing, a sensor is arranged inside the sealed casing, the other end of the water pipe is provided with a water permeable component, a water injection hole is formed in the sealed casing, the water injection hole is sealed through a sealing cover, and the sensor is communicated with the outside through a cable; a protecting casing is arranged at the exterior of the sealed casing. The osmometer provided by the invention is mounted outside a drill hole, during a long term observation process, if the sensor is damaged, in time maintenance or replacement can be performed, and the recovery and utilization of the sensor can be further achieved.

Description

technical field [0001] The invention relates to the field of piezometer equipment, in particular to a piezometer and a method for easy sensor replacement. Background technique [0002] The existence of water has an important impact on geotechnical engineering. In geotechnical engineering, in order to prevent natural disasters such as landslides and ensure the safety of the dam, it is necessary to measure the water level and seepage data of the groundwater level, reservoir water level, and dam infiltration line. , the conventional piezometer is buried at the bottom of the borehole, and the piezometer is buried at the bottom of the hole for a long time, and it is easy to break down, and the borehole is sealed with cement, which is inconvenient to repair and replace the piezometer. [0003] Therefore, how to design a piezometer that is more convenient for maintenance and replacement is a problem to be solved by those skilled in the art. Contents of the invention [0004] The...
