Abstract

The present invention discloses a single-point temperature compensation multi-functional intelligent anchor pole and an installation laying method thereof. The pole comprises a non-welding long-gauge multi-grating sensor with temperature compensation, epoxy resin or anchor adhesive, armored cables and a soft plastic sleeve. The non-welding long-gauge multi-grating sensor includes a plurality of long-gauge fiber grating sensing units which are in non-welding series connection in order and a temperature compensation sensing unit in the same non-welding series connection at the top. Two ends of the fibers of the long-gauge fiber grating sensing units are respectively fixed at the anchoring points of the sleeve, one end of the fiber of the temperature compensation sensing unit is connected with the long-gauge fiber grating sensing units themselves and is fixedly connected with the sleeve at the anchoring points, and the other end of the fiber of the temperature compensation sensing unit is free. The single-point temperature compensation multi-functional intelligent anchor pole and the installation laying method thereof can be applicable to anchoring reinforcement in the related engineering such as the construction, the tunnel, the minerals and the like, can monitor the carrying capacity, the strain stress and the damage situation of the anchor rod, and can be configured to monitor the surrounding rock support, the surrounding rock convergence and deformation and stability, etc.

Description

technical field

[0001] The invention relates to a multifunctional intelligent monitoring bolt for tunnels, rock soil and slope engineering, which is mainly used for monitoring the bearing capacity, stress and strain, and damage of bolts in related projects such as civil engineering, tunnels, and mining. Monitoring can also be used for surrounding rock support and monitoring of surrounding rock convergence deformation and stability. At the same time, the anchoring and strengthening effect of the bolt itself has not changed. To its original anchoring and strengthening effect on surrounding rocks, slopes, retaining walls, etc. Background technique

[0002] Bolt support is a reinforcement and support method used in surface engineering such as slopes and deep foundation pits, as well as underground chambers such as tunnels and stopes. Bolt support is to change the mechanical state of the surrounding rock itself through the bolt inside the surrounding rock, forming an integral an...
