Description
Technical field
This utility model relates to the neck of middle displacement measurement in tunnel and underground structure, Geotechnical Engineering indoor model test
Territory, particularly relates to the field of country rock large deformation.
Background technology
Show according to related data, along with the sustained and rapid development of China's traffic civil engineering, a large amount of execution conditions and geological conditions
Bad engineering continues to bring out, the weak large deformation harm particularly occurred in tunnel structure digging process, is not only and causes tunnel
Safety problem in road work progress, is also the huge potential safety hazard of later stage operation simultaneously.
In order to solve this difficult problem, using model test method to carry out studying is one of the most universal research method, right
In the situation of country rock large deformation, country rock ground, the Changing Pattern of displacement is the content that must carry out testing, but current institute
The method used mainly uses clear glass external observation and blister copper pipe to draw observation etc., also has some novel methods, in full
, in above all of method, each there is certain drawback in word imaging technique, test optical fiber etc., such as clear glass test essence
Degree is not, the interference of blister copper pipe test is relatively big, the reliability of imaging technique and test optical fiber not and the most directly perceived etc..
Utility model content
In view of the disadvantage mentioned above of prior art, the purpose of this utility model is to solve present case drag process of the test
The reliability of displacement measurement and intuitive in middle ground.
The purpose of this utility model is to be realized by following means: in a kind of country rock ground, displacement laboratory test model is auxiliary
Help measurement apparatus, there is a plurality of measurement branch road.Each by stator, rigidity rope, conduction pipe, elastic threads and loading bench outside consolidate
Determine framework to constitute: stator connects firmly with tested simulation country rock；One end of rigidity rope is connected with stator after conduction pipe, rigidity
The other end of rope couples with elastic threads after being overlapped on the upper boom of fixed mount vertically downward；The other end of elastic threads is fixed on fixing structure
The lower beam portion of frame；Rigidity rope is provided with the mark rigidity reel for rope measurement slide sign to displacement with near elastic threads interface；?
The displacement transducer measuring slide sign displacement it is provided with in fixed frame near described measurement slide sign.
This utility model device during tunnel and underground structure, Geotechnical Engineering indoor model test displacement
Measurement.Stator is fixed on the country rock position set in advance of test simulation, rigidity rope and stator secure bond；By hole
Interior displacement introduces and measures outside hole.Conduction pipe is used for protecting rigidity rope not by the frictional influence of the soil body, in a conduction pipe
Many rigidity ropes can be placed, ensure rigidity rope non-interference by position reserved in the sealing of conduction pipe, extraction firm
Property rope elastic threads and loading bench outside fixing component connect, sheet be adhesively fixed simultaneously on rigidity rope, connect amesdial or displacement
Sensors etc. carry out the test of displacement.Elastic threads is for ensuring that the straight of rigidity rope, and stator is to ensure that rigidity rope is with the soil body
Displacement convenient test.
In this utility model country rock ground, displacement laboratory test model-aided measurement apparatus effectively solves certainty of measurement not
Foot and the intuitive measured, add the quantity of measuring point simultaneously, and the test field impact overall on test is less, the effect of test
Good.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of utility model works principle.
Detailed description of the invention
Below in conjunction with the accompanying drawings structure of the present utility model is described in further detail.
In Fig. 1, stator 1, rigidity rope 2, conduction pipe 3, elastic threads 4, interface 5, upper boom 6, lower beam 7, displacement transducer
8。
In country rock ground, displacement laboratory test model-aided measurement apparatus has a plurality of measurement branch road；Each by stator 1,
Fixed frame outside rigidity rope 2, conduction pipe 3, elastic threads 4 and loading bench is constituted: stator 1 connects firmly with tested simulation country rock；Just
Property rope 2 one end through being connected with stator 1 after conduction pipe 3, the other end of rigidity rope is vertical after being overlapped on the upper boom of fixed mount
Couple with elastic threads 4 downwards；The other end of elastic threads is fixed on the lower beam 7 of fixed frame；Rigidity rope joins with elastic threads
The mark rigidity reel for rope measurement slide sign to displacement it is provided with near contact 5；Set in fixed frame near described measurement slide sign
It is equipped with the displacement transducer measuring slide sign displacement.
Without loss of generality, described measurement slide sign may be provided at any position on rigidity rope near elastic threads interface 5.?
Interface 5 is directly used by the present embodiment as measuring slide sign.In the present embodiment, displacement transducer uses dial gauge, just
Property rope use one section of seizing wire, conduction pipe use fine steel tube, elastic threads is rubber strip.
