A method for embedding monitoring measuring points

Abstract

The invention belongs to the technical field of tunnel engineering monitoring and measurement, and in particular relates to a monitoring and measuring point embedding method. The anchor rod of the present invention is directly connected with the surrounding rock, and a protective mechanism is set on the periphery, so that the anchor rod is not affected by the subsequent primary support and can directly and accurately reflect the state of the surrounding rock. At the same time, the protective mechanism It also plays an isolation and protection role for the monitoring mechanism, avoiding bumping, scratching and deformation of the monitoring mechanism, further ensuring the measurement accuracy, and has great promotion value and broad application prospects.

Description

technical field [0001] The invention belongs to the technical field of monitoring and measurement of tunnel engineering, and in particular relates to a monitoring and measurement point burying device and method. Background technique [0002] Monitoring and measurement refers to the technical means of using monitoring instruments to monitor various control indicators of key parts in the process of civil engineering construction. When the monitoring value is close to the control value, an alarm is issued to ensure the safety of construction. It can also be used for Check whether the construction process is reasonable. In tunnel engineering, due to the redistribution of surrounding rock stress and the gradual release of foundation stress during the construction process, changes in the construction environment, such as vault subsidence, side wall convergence, surface subsidence, etc., will occur. In the event of a safety accident, the rescue is extremely difficult, the social i...

Problems solved by technology

[0005] However, most of the current conventional monitoring technologies have one drawback. The most prominent one is that during the tunnel construction process, the erection and dismantling of scaffolding and the operation of large-scale mechanical equipment may bump into the monitoring points, and the blasted gravel on the face of the tunnel may also be damaged. It may hit the monitoring measuring points, which will cause the measuring points to deform, affect the accuracy of monitoring on both sides, and then have a major impact on the safety of the construction, and even cause catastrophic accidents after the tunnel is put into use due to hidden dangers

Although there are some technical solutions, such as patents CN207963889U, CN208765722U, etc., protective measures have been taken to protect the monitoring measurement points, but the monitoring measurement points are not directly in contact with the surrounding rock, and cannot directly and accurately reflect the state of the surrounding rock.
