Device, 3 horizontal bubbles and 3 total powerstations test prism；
3 horizon rules connect into an equilateral triangle, and telescopic device is arranged on each horizon rule, pass through flexible dress
The length for adjusting horizon rule is set, horizontal bubble, the junction setting one of two neighboring horizon rule 1 are centrally located on each horizon rule
A total powerstation tests prism.
The total powerstation test prism includes prism head and prism bar；
Prism head is arranged by prism bar in one end of horizon rule, and 3 prism bars are separately positioned on what 3 horizon rules were constituted
Equilateral triangle is three apexes, and prism bar is vertical with the plane where equilateral triangle.
The horizon rule is invar sclae.
Two tie points are connected by invar hinge in three tie points of 3 horizon rules, another tie point is by recklessly
Adjusting bolt necklace.
Beneficial effects of the present invention are：
The present invention, which devises one kind, to utilize total powerstation to have prism method to measure calculating bridge pier column or cylinder
The method of the central coordinate of circle of structure, every invar sclae of the present invention are all provided with there are one total powerstation test prism, and prism is vertically-mounted
In the end of each invar sclae, the prism levels that horizon rule connects are rotated to prism facets and face total powerstation installation position.It utilizes
Total powerstation has carried out prism measurement, measures three point coordinates, asks incenter coordinate to acquire surveyed component using three point coordinates and justifies
Heart coordinate.The present invention substantially increases measurement accuracy (speculating according to field measurement, can precision be improved an order of magnitude), and
Measurement method is convenient, can carry out big discharge observation, equipment prolonged and repeated can utilize, at low cost.
