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
The present invention relates to the monitoring measurement field, vault settlement point measurement mechanism and method for embedding in specifically a kind of tunnel monitoring measurement.
Background technology
The monitoring measurement technology is the important component part of modern constructing tunnel; It is the important means of monitoring country rock and structural stability; When carrying out constructing tunnel, especially above surrounding rock tunnel construction monitoring measurement is absolutely necessary for the IV level, and it is to guarantee the preliminary bracing safe and reasonable; Confirm that secondary lining executes the critical process of the time of work, and each working procedure in the hole is connected important directive significance is arranged.Revise design parameter through monitoring measurement and timely information feedback, with reach reasonable in design, the purpose efficiently of constructing.After the underground cavern excavation, country rock periphery convergence and vault sink be the reflection country rock with support system mechanics condition the most directly, the most tangible physical quantity, monitor the steady state (SS) that can understand country rock and support system through country rock convergence and vault sinking.Monitoring measurement can be in the work progress in tunnel; Measurement to country rock and supporting, lining cutting force and deformation state; Through the analysis of measurement being judged the stability and the stress-strain state of surrounding rock supporting, judge whether tunnel and country rock are stablized and safety, and proofread and correct, revise the design and guidance construction thus; Evaluation preliminary bracing and two lining designed rationality, thereby guiding construction, Feedback Design and design is optimized.
At present, Sopwith staff and spirit-leveling instrument are usually used in the monitoring of large cross-section tunnel vault settlement point, still, the error of Sopwith staff is bigger, has influenced monitoring accuracy to a great extent.
Summary of the invention
The objective of the invention is for overcoming the deficiency of above-mentioned prior art, vault settlement point measurement mechanism and method for embedding in a kind of simple in structure, cost is low, error is little tunnel monitoring measurement is provided.
For realizing above-mentioned purpose, the present invention adopts following technical proposals:
Vault settlement point measurement mechanism in a kind of tunnel monitoring measurement; Comprise steel tape, plummet, pole cap, expansion link and measuring point hook; Steel tape one end is provided with measuring point hook and pole cap; The other end is provided with plummet, and expansion link one end is sheathed in the pole cap, can measuring point hook and the measuring point that vault place, tunnel lays be joined when expansion link is propped up.
Said measuring point hook and pole cap are arranged side by side in steel tape one end, and the measuring point hook is opposite with the pole cap opening direction.
The said plummet that is arranged at steel tape one end is freely placed during use, is used for stretching steel tape.
Said expansion link diameter equates with the pole cap internal diameter.
The method for embedding of vault settlement point measurement mechanism in the tunnel monitoring measurement, step is following:
(1) pole cap is sheathed on expansion link one end;
(2) expansion link is elongated, simultaneously steel tape is launched;
(3) propping up expansion link joins measuring point hook and the measuring point that vault place, tunnel lays;
(4) pack up expansion link, plummet is hung on the steel tape other end, freely places, and steel tape is stretching, and the good spirit-leveling instrument of frame just can be measured.
The measuring point hook of steel tape one end of the present invention is used to connect the measuring point that vault place, tunnel lays; During use; Expansion link one end is sheathed in the pole cap, and propping up expansion link can join measuring point hook and the measuring point that vault place, tunnel lays, and plummet hang on the steel tape bottom; Freely place, be used for stretching steel tape.The present invention has advantages such as the manufacturing materials cost is low, and distribution method is simple, and error is little.
