The water mark patch (11) is a bar code water mark patch, and the measurement precision of the water mark patch can reach 0.01 mm.
The dust cover (3) is made of rubber.
The using method of the invention comprises the following steps:
the dust cover is sleeved in the lower end of the self-hook and fixedly welded with a ball head of the spherical universal joint, a bolt penetrates through a through hole in a U-shaped clamp and is screwed and fixed through a fastening nut, the U-shaped clamp is sleeved at the upper end of the ruler body and is anchored by using a rivet, a standard mark patch is adhered to the ruler body, and then a screw hole at the lower end of the spherical universal joint is connected with the bolt through a screw, so that the integral assembly of the monitoring ruler is completed; when the deformation of the surrounding rock of the cavern is monitored, the monitoring ruler is hung behind an embedded part of a fixed part to be detected of a cavern arch, and the U-shaped stable end is propped tightly and stably, so that the deformation monitoring work of the surrounding rock of the cavern can be carried out by using the high-precision electronic level, and after the use, the monitoring ruler is taken down, cleaned and maintained, and the next monitoring work is waited.
The invention has the beneficial effects that:
the high-precision tunnel vault arch deformation monitoring ruler is used, the work that a monitoring instrument needs to be buried in a vault arch deformation part during tunnel excavation is omitted, the monitoring ruler can be directly hung at the top of a tunnel formed by excavation during measurement at each time, then a precision level is adopted for direct observation, measurement data is obtained through implementation, the monitoring ruler can be taken down and taken away after use, and the monitoring ruler is reused next time, so that the problem that the monitoring instrument needs to be buried and installed in the vault arch monitoring in the past is solved, the monitoring ruler has the main function of adopting a 6061 aluminum alloy square tube as a ruler body, has high corrosion resistance and deformation resistance, a pasted bar code level label upgrades the precision when a tower ruler is adopted for measurement before to 0.01 millimeter level, the tunnel monitoring precision is greatly improved, the tunnel vault surrounding rock deformation monitoring work is more rapid, more accurate, time and labor saving are realized, and the meter level of convenience in installation is realized, The investment is small, the device is economical and practical, the working efficiency is improved, and the economic benefit is generated.
