Description
Technical field
A kind of tunnel tunnel face extrusion deformation measuring device of the utility model, is related to one kind in constructing tunnel, to area
Face carries out the device of shape changing detection, belongs to constructing tunnel field.Simple, the easy to use face shape of more particularly to a kind of construction
Become measurement apparatus.
Background technology
At present, during tunnel construction, increasing Support System in Soft Rock Tunnels is run into, these tunnels are usually expressed as enclosing
Rock deformation is big, or even the security incident such as cave in, and design for change is more, causes investment to be difficult to control to, construction speed slowly, seriously
The consequences such as the duration of engineering constraint, for the purpose for reaching effective deformation controlling for rock surrounding gateways, ensureing adjoining rock stability, it is desirable to take corresponding
Countermeasure is controlled respectively, in the various engineering measures of existing control face surrouding rock deformation, wherein most commonly seen one kind is
Face glass fibre anchor pole, the construction of face glass fibre anchor pole needs the plenty of time, it is meant that face dead time
It is longer, it is unfavorable for face adjoining rock stability, to ensure adjoining rock stability, it is necessary to adopt an effective measure and face extrusion deformation is carried out
Monitoring measurement, the domestic measuring equipment on front of tunnel heading extrusion deformation is seldom at present, and the external slide attack introduced
It is too high with the disposable purchase cost of incremental elongation meter.
The content of the invention
In order to improve above-mentioned situation, a kind of tunnel tunnel face extrusion deformation measuring device of the utility model is applied there is provided one kind
Work is simple, face deformation measuring device easy to use.It is with low cost, it is easy to promote the use of.
A kind of tunnel tunnel face extrusion deformation measuring device of the utility model is realized in：A kind of tunnel of the utility model
Road face extrusion deformation measuring device by supporting plate, strain gauge means, vertical rod, riser, test bar, be oriented to gum cover, drawstring, should
Force measuring device, bottom plate, supporting plate, connecting shaft and cross bar composition, three risers are sequentially placed on bottom plate, two neighboring riser it
Between angle be 135 degree, guiding gum cover is equipped with the middle part of the riser, test bar one end is placed in guiding gum cover, and passes through drawstring
It is connected with supporting plate, supporting plate is placed on bottom plate, stress measurement device is equipped with the drawstring, two vertical rod one end is hung down respectively
Disposed upright is on bottom plate, and cross bar one end is connected by connecting shaft with the vertical rod other end, and supporting plate is placed on the cross bar other end, the support
Strain gauge means are equipped with plate.
In use, three test bars are driven in vault face respectively first, then by two strain gauge means and three
Stress measurement device is connected by cable with outside platform of internet of things respectively, is stood a period of time, is switched on power, two strains
The data transfer detected just can be given outside platform of internet of things by measurement apparatus and three stress measurement devices respectively, work as data
After stable, record, then start tunnelling work, when face advances, the soil layer for encircleing top face is downward, three
Test bar is respectively by downward pressure, so as to there is the stress measurement on a pulling force, three drawstrings to connected drawstring respectively
Device is changed, and the data detected are transferred into outside platform of internet of things again, meanwhile, vault face pushes face, makes
Area facial disfigurement, so that two supporting plates being attached on face change, the strain gauge means on two supporting plates occur
The data of detection are transferred to outside platform of internet of things, outside platform of internet of things remembers the data received again by change again
Whether record is got off, and is contrasted with initial data, judge area facial disfigurement in the range of safe construction, it is to avoid landslide, the support
The quantity of plate, can according to actual needs be set, be reached during constructing tunnel, and area facial disfigurement is measured
Purpose.
Beneficial effect.
First, it is simple in construction, it is convenient and practical.
2nd, it is with low cost, it is easy to promote.
Brief description of the drawings
Accompanying drawing 1 is the structural representation that a kind of tunnel tunnel face of the utility model extrudes deformation measuring device.

Wherein part is：Supporting plate（1）, strain gauge means（2）, vertical rod（3）, riser（4）, test bar（5）, it is oriented to gum cover
（6）, drawstring（7）, stress measurement device（8）, bottom plate（9）, supporting plate（10）, connecting shaft（11）, cross bar（12）.
Embodiment：
A kind of tunnel tunnel face extrusion deformation measuring device of the utility model is achieved in that in use, first by three
Individual test bar（5）Drive in respectively in vault face, then by two strain gauge means（2）With three stress measurement devices（8）Point
It is not connected by cable with outside platform of internet of things, stands a period of time, switch on power, two strain gauge means（2）With
Three stress measurement devices（8）Just outside platform of internet of things can be given by the data transfer detected respectively, after data stabilization,
Record, then start tunnelling work, when face advances, the soil layer for encircleing top face is downward, three test bars
（5）Respectively by downward pressure, so that respectively to connected drawstring（7）There are a pulling force, three drawstrings（7）On stress survey
Measure device（8）Change, the data detected are transferred to outside platform of internet of things again, meanwhile, vault face pushes area
Face, makes area facial disfigurement, so that two be attached on face supporting plate（1）Change, two supporting plates（1）On strain survey
Measure device（2）Change, the data of detection are transferred to outside platform of internet of things again, outside platform of internet of things will be received
Data record again, and with initial data contrast, judge area facial disfigurement whether in the range of safe construction, it is to avoid
Landslide, the supporting plate（1）Quantity, can according to actual needs be set, be reached during constructing tunnel, to face
Deform the purpose measured.
During practice, the strain gauge means and stress measurement device are not restricted to a certain brand and type
Number.The utility model need not make explanations, it is necessary to illustrate to this, and outside platform of internet of things is not knot of the present utility model
Structure, is not belonging to protection domain of the present utility model, the computer journey that the strain gauge means and stress measurement device are loaded
