Abstract

The invention discloses a rock-soil pressure sensor embedding device and an embedding method thereof. The rock-soil pressure sensor embedding device comprises a cylindrical thin-wall vessel, a base, an upper sealing strip, a lower sealing strip, a lining, an outer lining, a band and a pressure sensor. The embedding method includes: arranging the soil pressure sensor embedding device, digging an embedding hole, levelling the basal plane of the sensor, inverting the pressure sensor embedding device, backfilling the original soil material, extracting the cylindrical thin-wall vessel, and backfilling and so on. By means of the rock-soil pressure sensor embedding device and the embedding method thereof, the digged pit slot is small, the size of a protecting layer needed for the sensor is small, the embedding efficiency is improved, the measuring precision is improved, the protecting layer is avoided from loosening in vibration rolling, and the problem of embedding the sensor in coarse granular materials is solved.

Description

technical field

[0001] The invention belongs to the field of geotechnical engineering, in particular to a device for embedding a rock-earth pressure sensor and an embedding method thereof. Background technique

[0002] In the current geotechnical engineering, water conservancy and hydropower engineering, and water transportation engineering construction, more and more geotechnical pressure sensors are used to measure the pressure in the medium of coarse-grained materials. Monitor the earth pressure of key parts of the dam body; in road engineering, it is necessary to monitor the subgrade reaction force, and in water transportation engineering, it is often necessary to bury earth pressure gauges to monitor the structural safety; in addition, in scientific research on coarse-grained materials, it is often necessary to The in-situ rock-soil stress data cannot be obtained by conventional indoor experiment methods due to its large particles, and can only be obtained by embedding ...
