Abstract

The invention relates to an auxiliary device for anti-destructive monitoring and measurement of convergence points in the tunnel engineering and a method for burying the auxiliary device. The auxiliary device comprises an embedded fixed rod, a threaded caliper retaining groove, a thread head, a measuring point connecting rod, a measuring point hook and a dustproof protective cover, wherein a conical drilling head is formed at one end of the embedded fixed rod, the embedded fixed rod can be fixed in a tunnel side wall by putting the conical drilling head into a drilled hole and reinforcing by using an anchoring agent when the embedded fixed rod is buried, and the threaded caliper retaining groove is formed at the other end of the embedded fixed rod and can be closely connected with the thread head of the measuring point connecting rod; the measuring point hook is arranged at one end of the measuring point connecting rod, and is used for connecting a steel ruler convergence meter for measurement and connecting a convergence hook on the steel ruler convergence meter during measurement; and the thread head is formed at the other end of the measuring point connecting rod. The entire embedded fixed rod is embedded into the tunnel side wall when the measurement is not performed, so measuring points can be effectively prevented from being damaged by blasting flyrocks or forklifts; meanwhile, the invention also has the advantages that: the cost of manufacturing materials is low, the arrangement method is simple and the like.

Description

technical field

[0001] The invention relates to the field of monitoring and measuring, in particular to an auxiliary device and embedding method for anti-destructive monitoring, measuring and converging measuring points in tunnel engineering. Background technique

[0002] Monitoring and measurement technology is an important part of modern tunnel construction and an important means to monitor the stability of surrounding rock and structure. When carrying out tunnel construction, especially for the construction monitoring and measurement of surrounding rock tunnels above grade IV, it is essential. It is a key process to ensure the safety and reasonableness of the initial support and to determine the time of secondary lining construction, and it has important guiding significance for the connection of various construction processes in the cave. The design parameters are corrected through monitoring and measurement and timely information feedback to achieve the purpose of reaso...
