Description

Technical Field

[0001] The invention relates to the technical field of civil engineering, and in particular to a deep hole series sensor installation mechanism and a use method thereof. Background Art

[0002] During the construction and operation of the project, the impact of the exposed weak slip zones, faults and other adverse geological structures on the project can be quantitatively evaluated and dealt with, while the assessment of the impact of the unexposed hidden adverse geological structures on the project faces many difficulties.

[0003] In the process of engineering monitoring, there are mainly three problems: the first is the problem of accurate positioning and installation of sensors during multi-zone monitoring. Inaccurate positioning and installation of sensors will make it difficult to accurately capture the key data changes of hidden geological bodies. Especially when multiple sensors are required for serial monitoring, the accurate positioning and serial installation of sensors have become technical challenges that need to be solved urgently. The second is the problem that the feeding device cannot be withdrawn smoothly. When the feeding device cannot be withdrawn smoothly after the sensor installation is completed, the activity of the geological body will cause the feeding device to cause unnecessary interference or damage to the sensor, affecting its normal operation. In addition, the feeding device that cannot be withdrawn may also hinder subsequent monitoring work, making it difficult for the monitoring data to fully and accurately reflect the actual status of the project; the third is the installation of medium and long-distance sensors. For existing monitoring technologies, the accurate installation of medium and long-distance sensors is still a technical problem. In order to reduce the impact of the feeding device on the monitoring data, the feeding device commonly used in the industry is usually made of PVC material, but this material device is generally only suitable for the push of short-distance sensors, and it is difficult to install medium and long-distance sensors. It can be seen that the existing sensor installation mechanism has many shortcomings in the actual application process and cannot meet a series of requirements such as the accuracy of monitoring data and the increasingly deeper monitoring areas.
