Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] Such as figure 1 As shown, a vault settlement point measurement device in tunnel monitoring and measurement includes a steel tape measure 1, a plumb weight 4, a rod cap 3, a telescopic rod and a measuring point hook 2. One end of the steel tape measure 1 is provided with a measuring point hook 2 and a rod cap 3, and the other end is provided with a plumb weight 4. One end of the telescopic rod is sleeved in the rod cap 3. When the telescopic rod is propped up, the measuring point hook 2 and the tunnel vault can be arranged. The measuring points are connected. The measuring point hook 2 and the rod cap 3 are arranged side by side at one end of the steel tape 1 , and the measuring point hook 2 is opposite to the opening direction of the rod cap 3 . The plumb weight 4 that is arranged on one end of the steel tape measure 1 can be placed freely dur...

Abstract

The invention relates to a vault settlement point measuring apparatus in tunnel monitor measurement. The apparatus comprises a steel tape, a lead hammer, a rod cap, a telescoping rod and a measuring point hook. One end of the steel tape is provided with the measuring point hook and the rod cap, and the other end is provided with the lead hammer. The measuring point hook at one end of the steel tape is used for connecting measuring points laid at a tunnel vault. The invention also discloses a burying method of the apparatus simultaneously. In burying, one end of the telescoping rod is sleeved in the rod cap, the telescoping rod is supported to connecting the measuring point hook with the measuring points laid at the tunnel vault, and the lead hammer is arranged at a bottom of the steel tape with free disposition and is used for stretching the steel tape. The apparatus and the method have the advantages of a low cost of manufacture material, a simple laying method, a small error and the like.

Description

technical field [0001] The invention relates to the field of monitoring and measuring, in particular to a measuring device and embedding method for vault settlement points in tunnel monitoring and measuring. 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 reasonable design and efficient construc...
