Abstract
The utility model discloses a kind of embedding devices that convergence measuring point is surveyed for tunnel, including measuring point hook, bolt head, thread head, test tube forward position, screw callipers dislocation preventing slot, test tube, built-in expansion rod, expansion section of jurisdiction and frosted layer.Expansion rod is squeezed to rock mass direction the beneficial effects of the utility model are: turning bolt head, since expansion piece thickness is gradually increased to insertion direction, the squeezing action of expansion rod makes expansion piece expanding extruding country rock around, keeps the coupling of pile and country rock more preferable, measurement result is more accurate.The device of measuring point is wholly embedded into rock mass, is not easily susceptible to touch and be destroyed when measuring at the scene, so that guaranteeing measuring point completely is that measurement result is more true and reliable.Measuring point hook is arranged to annular shape, and the diameter of annulus matches with convergence gauge hook diameter of section, links up with that junction is difficult to slide to fall off in measurement, guarantees the stability of work.
Description
Technical field
The utility model relates to monitor fields of measurement, specially a kind of embedding device that convergence measuring point is surveyed for tunnel.
Background technique
In recent years as the demand of China's traffic construction is increasing, the quality and quantity of constructing tunnel have largely
Promotion, in Traffic Engineering Construction, constructing tunnel is a kind of architectural engineering complicated, Unpredictability is strong, constructing tunnel prison
Control measurement work is to ensure the important means of building safety, optimization design, the accuracy that ensures to construct, so Tunnel construction survey is supervised
It controls work and provides reliable guarantee for working security and accuracy.In constructing tunnel, by dynamic to tunnel surrounding
Monitoring measurement, grasp country rock dynamic and supporting construction working condition, to ensure the safety in tunnel, reach safety for tunnel engineering,
Save the purpose of construction investment.
When typically now Tunnel Engineering surveys country rock convergence, spiral is directly typically inserted into the anchoring accomplished fluently
Then Kong Zhong is added in Anchor Agent to hole.When carrying out convergence measurement around tunnel, Anchor Agent is difficult to be completely filled with this method
The gap of pile and drilling causes the coupling of pile and country rock poor, causes the inaccuracy of measurement result.
Summary of the invention
The purpose of this utility model is when solving current tunnel to survey the embedding pile of convergence measuring point, and Anchor Agent is difficult to be completely filled with
The gap of pile and anchor hole causes pile to be difficult to couple completely with country rock or the problem of coupling difference, and then the one kind proposed
The embedding device of convergence measuring point is surveyed for tunnel.
To achieve the above object, the utility model adopts the following technical solutions:
A kind of embedding device for surveying convergence measuring point for tunnel, including it is measuring point hook, bolt head, thread head, test tube, built-in
Expansion rod and expansion section of jurisdiction, described bolt head one end are connected with thread head, and the other end is connected with measuring point hook, described test tube one end
For the end of thread, it is provided with test tube forward position on the end of thread, the screw thread of the screw callipers dislocation preventing slot in the end of thread and thread head
Screw thread matches, and the test tube other end is expansion tube bit end, and an expansion rod, the test tube outer surface is arranged inside the test tube
It is provided with frosted layer.
Preferably, the diameter of the expansion rod is slightly less than the inside diameter of test tube, in order to the placement of expansion rod.
Preferably, the measuring point hook (1) is set as annulus, and annulus interior diameter and convergence gauge link up with diameter of section kissing
It closes.
Preferably, the expansion section of jurisdiction is divided into three pieces, i.e., one end of test tube is divided into the identical section of jurisdiction of three pieces size.
Compared with prior art, the utility model has the beneficial effects that
1, the pile of measuring point uses hollow test tube, places an expansion rod in test tube, and rotating bolt head when can squeeze
Expansion rod, expansion rod stress can generate the power to insertion direction, and since the thickness of expansion section of jurisdiction gradually increases, expansion rod can be squeezed
Section of jurisdiction is expanded, to make to expand section of jurisdiction spreading and squeeze country rock, while the outer surface of test tube is provided with frosted layer, increases expansion
The frictional force of section of jurisdiction and test tube itself and country rock is not likely to produce loosening, the coupling of lifting device and country rock.It will not when measurement
Because the loosening displacement of measuring point leads to measurement error.
2, difficult to slide when linking up with connection with convergence gauge by the way that measuring point hook is arranged to annular shape, guarantee measurement every time
When measuring point hook and convergence gauge hook be all connected to the same point, reduce the error of measurement, keep result more accurate.
3, after the utility model improves the fixation principle of setscrew, measuring point whole device is all embedded in rock mass
Portion prevents the destruction generated in the construction process to point equipment.
Detailed description of the invention
Fig. 1 is the utility model overall structure diagram
Fig. 2, Fig. 3 are expansion tunnel segment structure schematic diagram
In figure: 1, measuring point is linked up with；2, bolt head；3, thread head；4, test tube forward position；5, screw callipers dislocation preventing slot；6, test tube；

Specific embodiment
Below in conjunction with the attached drawing in the utility model, the technical solution of the utility model is clearly and completely retouched
It states, it is clear that the described embodiments are only a part of the embodiments of the utility model, instead of all the embodiments.Based on this
Embodiment in utility model, it is obtained by those of ordinary skill in the art without making creative efforts it is all its
His embodiment, fall within the protection scope of the utility model.
As shown in Figure 1, a kind of embedding device for surveying convergence measuring point for tunnel, the both ends of test tube 6 are respectively screw callipers
Dislocation preventing slot end 5 and expansion tube bit end 8, the inside of test tube 6 are placed with expansion rod 7, in use, by thread head 3 rotate into and its
In the screw callipers dislocation preventing slot 5 that screw thread matches, annular test tube forward position 4 is arranged in screw callipers dislocation preventing slot end, and 6 outer surface of test tube is set
Frosted layer is set, the presence of frosted layer increases the frictional force of expansion section of jurisdiction and test tube and country rock itself, makes the coupling of pile and country rock
The increase of conjunction property, 2 side of bolt head is arranged measuring point and links up with 1, and measuring point hook is arranged to circular link up with measuring point convergence gauge and is connected,
Sliding can be reduced.When this embedding device can effectively reduce convergence measurement because caused by loosening measuring point measurement error.
Specific workflow is as follows:
(1) expansion rod 7 is put into test tube, has then accomplished fluently the insertion of test tube 6 in the tunnel surrounding of drilling.
(2) thread head 3 is sufficiently connect by rotation bolt head 2 with screw callipers dislocation preventing slot 5 when measuring, and guarantees to have connected swollen
Tube expansion piece 8 can sufficiently be expanded to be tightly secured in together with country rock.
(3) the measurement hook of convergence gauge is connect with the measuring point hook 1 on bolt head, carries out convergence measurement.
