Problems solved by technology
[0002] The existing earth pressure sensor used to monitor the soil pressure change of the tunnel stratum is pre-buried in the stratum outside the tunnel ring during the tunnel construction process; with the long-term use of the earth pressure sensor, the earth pressure sensor will be damaged due to various reasons. damage, because the earth pressure sensor is pre-buried in the stratum outside the tunnel ring, and it cannot be replaced, which eventually leads to the failure of the tunnel stratum earth pressure change monitoring, but there is no technical means to solve this problem

A tunnel stratum soil pressure detection sensor comprises an installation fixing sleeve, an expansion pipe assembly and a sensor assembly. The expansion pipe assembly is provided with an expansion pipe which is fixedly arranged in an inner hole of the installation fixing sleeve, and the sensor assembly is fixedly arranged at the upper portion of the expansion pipe assembly. When the soil pressure detection sensor is constructed, the expansion pipe is arranged in a tunnel outer stratum at the outer side of a tunnel ring piece, the expansion pipe is expanded by filling the high-pressure working medium oil, and the working medium oil in the expansion pipe is communicated to the sensor assembly; when the pressure of the stratum outside the tunnel changes, the pressure acting on the outer wall of the expansion pipe changes, the pressure of working medium oil in the expansion pipe correspondingly changes, the change of the pressure of the working medium oil is transmitted to the sensor assembly, and a pressure change signal is output. When the tunnel stratum soil pressure detection sensor is damaged, repair can be carried out by replacing the expansion pipe assembly and the sensor assembly, and the problem that an existing damaged soil pressure detection sensor cannot be repaired is solved.
Description
Technical field [0001] The present invention relates to a technical field of earth pressure monitoring tunnel formation, in particular to a pressure detecting sensor Stratum tunnel and construction method. Background technique [0002] Soil conventional pressure sensor for monitoring the pressure change soil strata tunnel, the tunnel construction process in, embedded in the ground outside of the ring piece in the tunnel; pressure sensor with long term use of soil for various reasons would soil pressure sensor damage due to soil pressure sensors embedded in the ground outside the tunnel ring segment, it can not be replaced, so the final result in the failure to monitor pressure changes in the earth strata tunnel, but there is no technical means to solve this problem. Inventive content [0003] In order to overcome the deficiencies of the background art, the present invention discloses a pressure detecting sensor Stratum tunnel and construction method, tunnel Stratum pressure dete...
