In order to overcome the above-mentioned deficiencies of the prior art, the technical solution adopted in the utility model is:
A kind of forced centering structure for tunnel traverse survey inside tunnel, including bar steel plate, steel plate are two pieces of expanding screws
Silk is installed on the molded section of jurisdiction of subway or on tunnel double-lining, and inferior horn on bracket, water on bracket is respectively welded in two pieces of bar steel plates
Flat welded stainless steel plate, stainless steel plate centre soldering stainless steel bolt, stainless steel bolt connect total station or the flat pedestal of essence, whole station
360 ° of prism heads are installed on instrument or the flat pedestal of essence.
It is reinforced between the setscrew and steel plate using double nut.
The steel plate and bracket uses two-sided welding.
The stainless steel plate size is 200mm × 200mm × 5mm, is square shape
The stainless steel bolt is having a size of φ 16mm.
The bracket all uses φ 20mm round steel to carry out processing welding.
The stainless steel bolt should be greater than 300mm apart from tunnel duct piece or two lining distances, to reduce light folding by tube wall
Projection is rung.
The stainless steel bolt and stainless steel plate welding position must be polished flat, in order to total station pedestal or accurate adjustment base
Seat bottom surface connects closely connected with steel plate device top surface.
Compared with prior art, it is had the beneficial effect that possessed by the utility model
A kind of detachable forced centering apparatus for tunnel traverse survey inside tunnel, device noumenon are added using live material
Work forms, and processing cost is low；Cooperate 360 ° of prisms that can meet any observation angle requirement under extreme conditions；Shelf bracket is adopted
It is attached fixation with pre-buried expansion bolt, may be reused；It drills in suitable targets position, it will be swollen using anchoring adhesive
Swollen bolt embedment is installed on above pre-buried good expansion bolt on section of jurisdiction, then by entire bracket, passes through spacer for bolt adjustment support
Frame horizontality can tighten four bolts after bracket meets level requirement.After anchoring adhesive solidification, it can be used as measuring
Target point uses.Measurement target multi-angle observation may be implemented in the present apparatus, and applicability is wide, structure is simple, easy for installation, stability
By force, processing cost is low, occupies little space, easily recognizes, and has good promotion and application value.
