Description
Technical field
The utility model is related to the non-contact monitoring measurement fields in underground engineering construction field more particularly to tunnel.
Background technology
Monitoring measurement is the critical process of constructing tunnel, is the important component of site operation tissue, with tunnel perimeter
Environment and construction safety, quality, progress are closely connected.The method of tunnel monitoring measurement mainly taps tactile measurement method and non-connects
Measurement method is touched, there are significant limitations due to contact method for measurement, have been unable to meet modern construction requirement, at present constructing tunnel
Measurement is generally monitored using Non-contact measurement.
Non-contact measurement fado uses the embedded bracket in tunnel surrounding and preliminary bracing at this stage, pastes reflection on stent
Piece is monitored measurement using the method that total powerstation is observed.In entire observation cycle, stent is fixed in tunnel wall,
Stent and reflector plate are irremovable.Therefore it is measured using this method there are many deficiencies, such as：Reflector plate is exposed to construction environment
In, it is easily polluted by dust and Gunning material, conditioned reflex is poor, influences to observe data acquisition；Frameworks exposure is partially disposed in tunnel
It on wall, is easily disturbed or destroys by blasting flyrock, construction machinery, if by slight perturbations, survey crew can be mistakenly considered disturbance
Displacement is the deformation of measuring point, and judges the stability of country rock by accident；If being destroyed, cause metric data discontinuous, and need to bury again
If observation mark；Construction interference is big in tunnel, narrow space, and with the progress of construction, the position of survey station and elevation are varied from,
It cannot be guaranteed that the best observation angle of measuring instrument and reflector plate, accuracy in measurement and reliability cannot be guaranteed；Stent can not weigh
Multiple to utilize, observation material cost input increases.
Invention content
Problem to be solved in the utility model provides a kind of preservation easy to disassemble and convenient for adjusting aiming above insufficient
Save the measurement reflection plate rack of best observation angle.Its technical solution is as follows：
It includes anchoring section and active segment, and anchoring section includes anchor bar and sleeve, and active segment includes cartridge and U-shaped frame,
Cartridge includes cassette bottom, box wall and box top, cartridge cassette bottom and sleeve connection, cartridge box top center opening by radial rotary bolt with
U-shaped frame connects, and axial-rotation bolt, axial-rotation bolt middle part fixation reflex piece pasting board are installed on U-shaped two side leg of frame.
The cartridge passes through connecting screw and sleeve connection.
Compared with prior art, the utility model has an advantageous effect in that：
1st, stent is divided into anchoring section and active segment two parts, and active segment stent detachably preserves after each observation,
It avoids in work progress to the damage of observation mark, disturbance, avoids the pollution to observation mark such as dust, Gunning material, observe item
Part is greatly improved, and avoids the erroneous judgement to surrounding rock stability, ensure that the continuity of metric data.
2nd, cartridge top is bolted with U-shaped frame by radial rotary, and axial-rotation spiral shell is installed on U-shaped two side leg of frame
Bolt, radial rotary bolt and axial-rotation bolt form Universal rotary device, and measuring instrument is made to reach best observation with reflector plate
Angle ensures accuracy in measurement and reliability.
3rd, active segment stent and reflector plate detachably reuse, and reduce the expense generated because repairing observation mark, reduce
Observation material input, has saved material cost.
4th, active segment is detachable, eliminates in work progress to the protected working of observation mark, shortens process circulation time,
Reduce artificial input, save construction cost.
Description of the drawings
Fig. 1 is the utility model structure diagram；
Fig. 2 is the utility model left view；
Fig. 3 is the utility model usage state diagram.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
Referring to Fig. 1~Fig. 3, the utility model includes anchoring section and active segment, and anchoring section is embedded in country rock 12 and initial stage branch
In protection structure 11, including anchor bar 1 and sleeve 2, anchor bar 1 and sleeve 2 are welded；Active segment is frameworks exposure portion
Point, active segment can integral demounting reuse, active segment include cartridge 4 and U-shaped frame 7, cartridge 4 include cassette bottom 41,42 and of box wall
Box top 43, cartridge cassette bottom 41 are threadedly coupled with the sleeve 2 of anchoring section, and 43 center opening of cartridge box top passes through radial rotary bolt 6
It is connect with U-shaped frame 7, specifically 6 head of radial rotary bolt is snapped in cartridge 4, and tail portion is connect with U-shaped 7 bottom of frame, box apical pore
Diameter is slightly larger than the screw diameter of radial rotary bolt 6, and screw rod can be enable to be freely rotated across box top and enable box top 43
Bolt head is enough blocked, prevents cartridge 4 with radial rotary bolt 6 from being detached from；Axial-rotation spiral shell is installed on U-shaped 7 liang of side legs of frame
Bolt 8,8 middle part fixation reflex piece pasting board 10 of axial-rotation bolt, radial rotary bolt 6 and axial-rotation bolt 8 form Universal rotary
Rotary device.
The cartridge 4 is threadedly coupled by connecting screw 3 with the sleeve 2 of anchoring section, and the length of connecting screw 3 is less than sleeve
2 length.
The radial rotary bolt 6 be equipped with radially braking nut 5, when reflector plate radiai adjustment in place after, tighten radially
Braking nut 5 plays braking action, prevents reflector plate radial rotating in observation process, ensures accuracy in measurement and reliability.
The axial-rotation bolt 8 is equipped with axial braking nut 9, axial to brake after reflector plate is adjusted axially in place
Nut 9 plays braking action, prevents reflector plate axial rotation in observation process, ensures accuracy in measurement and reliability.
Utility model works principle is as follows：
Stent anchoring section is embedded in country rock 12 and preliminary bracing structure 11 by tunnel before construction of shotcrete, set
2 nozzles of cylinder are flushed with preliminary bracing exposed face；Reflector plate first is pasted on the reflector plate pasting board of active segment before metrology operation, so
Connecting screw 3 is screwed in the sleeve 2 of anchoring section by silk tooth afterwards, until being screwed into cartridge cassette bottom 41 is close to sleeve 2, connecting screw 3
Rotate it is motionless until；Again by rotating radial rotary bolt 6, radiai adjustment is carried out to reflector plate, makes the U-shaped in face of standard of U-shaped frame 7
Observation instrument, while radially braking nut 5 is tightened, ensure that reflector plate does not rotate radially before observation terminates；Pass through axial direction again
Bolt 8 is rotated, reflector plate is adjusted axially, reflector plate is made to be directed at observation instrument, while tightens axial braking nut 9, is protected
Card reflector plate does not shake in an axial direction before observation terminates.This reversely rotates connecting screw 3 after measuring, and makes active segment and anchor
Gu section is detached from, recycling active segment stent preserves, and next time measures and repeats the above steps.After this sectional observation, active segment stent
It is repeatable to be used in follow-up section measurement.
