Description

The measuring point composite set that a kind of tunnel monitoring measurement is used
Technical field
The utility model relates to a kind of underground engineering wall rock deformation monitoring device, specifically a kind of measuring point composite set of tunnel monitoring measurement application.
Background technology
The monitoring measurement technology is the important component part of modern constructing tunnel, be monitoring country rock and Stability Analysis of Structures important means, when carrying out constructing tunnel, especially for
Figure 426449DEST_PATH_IMAGE001
The above surrounding rock tunnel construction monitoring of level measures and is absolutely necessary.In the tunnel excavation process, the release of the stress of country rock own is a slowly process, tunnel vault will produce sedimentation in this process, periphery can produce convergence, if construction section has unfavorable geology, molten water, outside additional load etc., sedimentation and rate of convergence will be accelerated, can produce landslide when serious, affect normally carrying out of constructing tunnel.Along with the promotion and application of New Austrian Tunneling Method, in soft rock mass, monitor surrouding rock deformation, become the important content of tunnel construction.Can predict the construction dangerous situation by monitoring measurement information, monitoring measurement also can provide feedback information, provide foundation for secondary lining reasonably applies time, the design of modification support system and change construction method for stability of surrounding rock, supporting and lining cutting reliability simultaneously.Be to reduce monitoring to the impact of constructing tunnel, adopt that conveniently monitoring method is particularly important.
At present, tunnel wall rock deformation monitoring method has a variety of, hangs chi such as various convergence gauges, precision level cooperation and measures convergence and sedimentation, and total powerstation and subsides reflecting prism are used the measurement sedimentation.Wherein, adopt total powerstation and the sedimentation of subsides reflecting prism test vault the most general, but owing to need to paste reflecting prism, measuring point cost height.
The utility model content
The problems such as the point equipment cost of using for tunnel monitoring measurement in the solution prior art is higher, the utility model is used for reference reflection plaster reflective characteristics under strong illumination, reflection plaster is bonded on the measuring point web member measuring point composite set that provides a kind of tunnel monitoring measurement simple in structure, that cost is low to use.
For solving the problems of the technologies described above the technical scheme that adopts: the measuring point composite set that a kind of tunnel monitoring measurement is used, this device mainly is comprised of fixed bar, measuring point web member and the circular tack that is arranged on the measuring point web member, be bonded with reflection plaster on the circular tack, one end of described fixed bar is connected by the clamping slot on screw thread and the measuring point web member, the other end is provided with expansion piece, also is provided with on the fixed bar for the rotating nut that compresses expansion piece.
Described circular tack is welded on the measuring point web member; Reflection plaster is bonded on the circular tack with double faced adhesive tape.
The center of described reflection plaster is provided with " ten " word mark, during work, the clamping slot of measuring point web member is connected with the thread end of fixed bar and screws, and the one side that makes circular flat headband reflection plaster is back to face, with the reflection plaster on the good torch irradiation measuring point of spotlight effect, adopt the relative distance of total station survey reflection plaster " ten " word mark and basic point, by the relatively change of twice relative distance in front and back, realize the monitoring of tunnel deformation, simple to operate, measuring accuracy is high, test speed is fast.
Also be provided with pad between described expansion piece and the rotating nut.
The beneficial effects of the utility model: the utility model is a kind of easy tunnel deformation measuring point composite set, can continual surrouding rock deformation to the whole process of constructing tunnel monitor; When tunnel deformation tends towards stability, the measuring point web member can be dismantled by the masterplate chassis, realize reusing of reflective measuring point, this point equipment has also been avoided the complicated processes of traditional extension prism method of testing simultaneously, that this device has is simple in structure, easy operating, advantage with low cost, improve in use measurement efficient, accelerated project progress.

Embodiment
Below in conjunction with drawings and Examples the utility model is described further.
As shown in Figure 1, the measuring point composite set that a kind of tunnel monitoring measurement is used, this device mainly is comprised of fixed bar 8, measuring point web member 3 and the circular tack 4 that is welded on the measuring point web member 3, be bonded with reflection plaster 5 with double faced adhesive tape on the circular tack 4, the center of reflection plaster 5 is provided with " ten " word mark, one end of described fixed bar 8 is connected by the clamping slot 6 on screw thread and the measuring point web member 3, the other end is provided with expansion piece 1, also be provided with on the fixed bar 8 for the rotating nut 7 that compresses expansion piece 1, be provided with pad 2 between expansion piece 1 and the rotating nut 7.
According to the Tunnel Engineering field requirement, set eyelet in the precalculated position of tunnel vault and sidepiece, fixed bar 8 is inserted in the eyelet, with spanner rotation rotating nut 7, by pad 2 extrusion expansion sheets 1, expansion piece 1 is expanded become large, the extruding country rock, thus fixed bar 8 is fixed on the tunnel side wall; Measuring point web member 3 and fixed bar 8 are bolted groove 6 are connected, groove 6 restriction forward displacements with bolts; When installing and fixing bar 8, the least possible exposing beyond tunnel side wall in the situation that guarantees the bolt connecting length avoids construction that it is damaged.Outside the tunnel, reach and bury the control reference point in the tunnel underground, be convenient to check.
When implementing to measure, according to tunnel internal situation choose reasonable total powerstation position, as shown in Figure 2, at first, with the elevation of total powerstation II test benchmark point III; Secondly, with the reflection plaster 5 on total powerstation II aligning tunnel vault, the abutment wall measuring point I, test its elevation and horizontal range.In test process, must be by the good torch irradiation measuring point of spotlight effect, in order to form the clearly visual field.
The difference of institute's survey vault point height and reference point elevation is that the vault point is with respect to the discrepancy in elevation of reference point, this discrepancy in elevation that records is deducted the discrepancy in elevation that surveyed last time, be the deflection X of this measurement and the interior vault of measurement period last time, the elevation that each test draws and the difference of testing first the elevation that draws are the accumulative total deflection of institute's measuring point; In this time measurement, a pair of two help the difference of the horizontal reading of measuring point to be the horizontal range of both sides point, the difference of this horizontal range and horizontal range that surveyed last time is the convergence value in this period, and each horizontal range of measuring is the accumulative total convergency value with the difference of the horizontal range of measuring first.After surrouding rock deformation tends towards stability, by the masterplate chassis connecting link on the measuring point is unloaded, in order to again layout use.
