Abstract
A kind of tunnel deformation observation mark, including anchoring section, observation bid section and connection sleeve.Anchoring section is fixed in preliminary bracing gunite concrete, anchoring section is mechanically connected with sleeve one end is connect, connection sleeve other end welding observation mark, after the completion of Tunnel gunite concrete, it drills in deformation observation mark design position, deformation observation mark is installed, it is only mechanical to dismantle observation mark part when observation mark is removed, the processing is simple for such deformation observation mark, low in cost, construction dismounting is quick for installation, reduces the quality and security risk of conventional construction.
Description
Technical field
The utility model belongs to technical field of tunnel construction, and in particular to a kind of tunnel deformation observation mark.
Background technique
At present in constructing tunnel, deformation monitoring measurement is to guarantee the important means of tunnel safety construction, more in high-speed rail construction
Using non-contact measurement, deformation observation target installation quality is directly related to the accuracy of deformation monitoring metric data, deformation
Monitoring parameter measuring point is more, amount is big, and while removing after deformation monitoring measures faces splash guard and is laid with operating area, and when dismounting mostly uses
Machine cuts, the deformation observation mark after cutting cancel, if cutting is not thorough, exposed parts will wear out splash guard, shadow
The waterproof effect for ringing tunnel, causes hidden danger of quality.
Summary of the invention
In order to overcome the above-mentioned deficiencies of the prior art, the purpose of the utility model is to provide a kind of tunnel deformation observation mark,
It is easy to process, it is low in cost, it firmly installs, can be recycled after dismounting, and there is no exposed parts after removing, ensure that tunnel
The construction quality of the accurate and splash guard of deformation monitoring metric data.
In order to realize that above-mentioned the deficiencies in the prior art, the technical solution adopted in the utility model are:
A kind of tunnel deformation observation mark, including anchoring section, anchoring section are fixed in preliminary bracing gunite concrete, anchoring section
It is mechanically connected with sleeve one end is connect, the connection sleeve other end welds observation mark.
The mechanical connection is to be threadedly coupled.
The anchoring section uses 22 steel bar meter of φ, after the completion of Tunnel gunite concrete, in design position
It sets and drills, drilling depth guarantees that anchoring section anchors into 25~30cm of basement rock, is fixed with early strong Anchor Agent, anchoring section and connector sleeve
The cylinder non-bulging gunite concrete face in coupling part.
The beneficial effects of the utility model are:
Deformation observation mark firmly installs, and the observation mark part of dismounting can recycle, and when dismounting is convenient and efficient, after dismounting
Gunite concrete face does not have exposed parts, reduces the hidden danger of quality of splash guard construction.
Detailed description of the invention
Fig. 1 is the elevation of the utility model.
Wherein, 1 is anchoring section；2 be connection sleeve；3 be observation mark.
Specific embodiment
The utility model is further discussed below below in conjunction with attached drawing.
As shown in Figure 1, a kind of tunnel deformation observation mark, including anchoring section 1, it is mixed that anchoring section 1 is fixed on preliminary bracing injection
In solidifying soil, anchoring section 1 welds observation mark 3 with 2 one end of sleeve mechanical connection, connection 2 other end of sleeve is connect.
The mechanical connection is to be threadedly coupled.
The anchoring section 1 uses 22 steel bar meter of φ, after the completion of Tunnel gunite concrete, in design position
It sets and drills, drilling depth guarantees that anchoring section anchors into 25~30cm of basement rock, is fixed with early strong Anchor Agent, while guaranteeing to be welded with
The anchoring section 1 of observation mark 3 with connect the non-bulging gunite concrete face in 2 coupling part of sleeve.Observation mark part and connection sleeve weldering
It connects in succession, after deformation observation, when deformation observation mark is removed, removes exposed observation mark part and connection sleeve.
