Background technique
The monitoring measurement technology is the important component part of modern tunnel construction; It is the important means of monitoring country rock and structure stability; When carrying out tunnel construction, 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 feedback information, 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 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.
Surrouding rock deformation data when excavating in order in time to obtain face, the monitoring point often is laid in apart from excavated section nearby, and the convergence measuring point hook of in the past laying; Expose outside abutment wall greatly; The drawback of doing like this is, because the explosion of face, rubble might be pounded the measuring point of laying; Perhaps remove the slag car and forklift and can run into measuring point, thereby cause the distortion of measuring point hook.
Summary of the invention
The objective of the invention is for overcoming the deficiency of above-mentioned existing technology; Tamper-proof monitoring measurement convergence measuring point auxiliary device and method for embedding in a kind of simple in structure, tunnelling works that cost is low is provided; Because embedded fixing rod of the present invention is not when measuring; All be embedded in the tunnel side wall, destroyed by blasting flyrock or forklift so can effectively prevent measuring point.
For realizing above-mentioned purpose, the present invention adopts following technical proposals:
Tamper-proof monitoring measurement convergence measuring point auxiliary device in a kind of tunnelling works; Comprise embedded fixing rod, screw callipers dislocation preventing slot, thread head, measuring point connecting rod, measuring point hook, dustproof protective cover; Said embedded fixing rod one end is conical Drilling head; The other end is provided with the screw callipers dislocation preventing slot, and measuring point connecting rod one end is provided with and is used to connect the measuring point hook that the steel ruler contraction meter is measured, the thread head of the other end for matching with the screw callipers dislocation preventing slot.
The end face that the screw callipers dislocation preventing slot is set on the said embedded fixing rod is provided with the annular groove of a placement dustproof protective cover.
It is consistent that shape on the thread head of said measuring point connecting rod and the embedded fixing rod in the screw callipers dislocation preventing slot is wanted, joint voidlessness when guaranteeing that each connection finishes.
Said embedded fixing rod integral body is all in tunnel side wall.
The method for embedding of tamper-proof monitoring measurement convergence measuring point auxiliary device in the tunnelling works, step is following:
(1) the conical Drilling head of embedded fixing rod is inserted among the country rock of tunnel-side, add the anchoring agent, make it be fixed on country rock inside; At last, dustproof protective cover is built;
When (2) measuring, take out the measuring point connecting rod, open dustproof protective cover, then the first end of the screw thread of measuring point connecting rod fully is connected with the screw callipers dislocation preventing slot of embedded fixing rod, and guarantee to connect joint voidlessness when finishing;
(3) the measurement hook of steel ruler contraction meter is connected with measuring point hook on the measuring point connecting rod, carries out convergence measurement;
(4) after measurement finishes, the measuring point connecting rod is unloaded, packs up, dustproof protective cover is built.
The present invention among the country rock of elder generation with the conical Drilling head insertion tunnel-side of embedded fixing rod, adds the anchoring agent in use then; Make embedded fixing rod fully fixing; And guarantee embedded fixing rod integral body all in tunnel side wall, and last, dustproof protective cover is built.During measurement, take out the measuring point connecting rod, open dustproof protective cover, the first end of the screw thread of measuring point connecting rod fully is connected with the screw callipers dislocation preventing slot of embedded fixing rod, and guarantee to connect joint voidlessness when finishing.Can the measurement hook of steel ruler contraction meter be connected with measuring point hook on the measuring point connecting rod then, carry out convergence measurement, after measurement finishes the measuring point connecting rod unloaded, packs up, dustproof protective cover is built.Because embedded fixing rod of the present invention when not measuring, all is embedded in the tunnel side wall, destroyed by blasting flyrock or forklift so can effectively prevent measuring point, simultaneously, the present invention also has advantages such as the Manufacturing material cost is low, and distribution method is simple.
