Abstract
The present invention relates to the measuring method of a kind of top of ultrahigh column absolute altitude, its step: (1), on ultrahigh column sidewall, measure a relief h；(2), there is the side distance controlling in the axial direction of relief h to set up total powerstation at the A point of ultrahigh column height 1.5 times in ultrahigh column；(3), measuring S1 distance bottom ultrahigh column along total powerstation direction determining B point, S1 controls at 0.2m 0.5m, sets up prism, measure horizontal range S at B point；(4), use total powerstation observation mark high point h, and record vertical angle α 1, record vertical angle α 2；, elevation of top H=h+tan α 2 × (S1+S) ± tan α 1 × (S1+S) of ultrahigh column, top of ultrahigh column level measurement is complete.Present invention reduces the working time, reduce work risk.And ensure that certainty of measurement, from the point of view of the angle saved, the present invention is the security context that engineering economy manpower and materials also improve work.
Description
Technical field
The invention belongs to measuring method field, the measurement side of a kind of top of ultrahigh column absolute altitude
Method.
Background technology
At present, the more large space that trends towards of public building, Suresh Kumar.Present large-scale ultrahigh column is very
Common and play main support effect between floors, whether the top mark height of pillar reaches to design requirement
Aobvious is particularly important.How the absolute altitude of height top of ultrahigh column more than 10 meters is carried out accurately
Measure, be a kind of relatively difficult thing.The method that the top mark of measurement ultrahigh column was high in the past is main
It is by adding after measuring the end absolute altitude of pillar that the physical length of pillar determines, or from pillar top
Portion directly measures downwards to pillar elevation of bottom with steel ruler, and the top mark being determined pillar is high.These are two years old
Planting measuring method and cannot react the elevation of top of pillar accurately, and take time and effort, danger compares
Greatly.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, it is provided that a kind of top of ultrahigh column mark
High measuring method, this measuring method is simple to operate, time saving and energy saving, and safety is high, can be effective
Raising certainty of measurement and speed.
The present invention solves its technical problem and is achieved through the following technical solutions:
The measuring method of a kind of top of ultrahigh column absolute altitude, its cast is inverse to be comprised the steps: as method
(1) on ultrahigh column sidewall, measure the relief h of 0.5m or 1m；
(2), there is the side distance controlling in the axial direction of relief h in ultrahigh column in ultrahigh column
Total powerstation is set up at the A point of highly 1.5 times；
(3), measuring S1 distance bottom ultrahigh column along total powerstation direction determining B point, S1 controls
0.2m-0.5m, at B point set up prism, with total station survey go out total powerstation to prism level away from
From S；
(4), use total powerstation observation mark high point h, and record vertical angle α 1, keep the level of total powerstation
Angle is constant, vertically upward observation pillar top, records vertical angle α 2；
, elevation of top H=h+tan α 2 × (S1+S) ± tan α 1 × (S1+S) of ultrahigh column,
Top of ultrahigh column level measurement is complete.
Advantages of the present invention and having the beneficial effect that
Present invention reduces the working time, reduce work risk.And ensure that certainty of measurement,
From the point of view of the angle saved, the present invention is the safety collar that engineering economy manpower and materials also improve work
Border.
Accompanying drawing explanation
Fig. 1 is instrumentation plan of the present invention (relief h is higher than B point prism)；
Fig. 2 is instrumentation plan of the present invention (relief h is less than B point prism).
Detailed description of the invention
Below by specific embodiment, the invention will be further described, and following example simply describe
Property, it not determinate, it is impossible to limit protection scope of the present invention with this.
The measuring method of a kind of top of ultrahigh column absolute altitude, its cast is inverse to be comprised the steps: as method
(1) on ultrahigh column sidewall, measure the relief h of 0.5m or 1m；
(2), there is the side distance controlling in the axial direction of relief h in ultrahigh column in ultrahigh column
Total powerstation is set up at the A point of highly 1.5 times；
(3), measuring S1 distance bottom ultrahigh column along total powerstation direction determining B point, S1 controls
0.2m-0.5m, at B point set up prism, with total station survey go out total powerstation to prism level away from
From S；
(4), use total powerstation observation mark high point h, and record vertical angle α 1, keep the level of total powerstation
Angle is constant, vertically upward observation pillar top, records vertical angle α 2；
, elevation of top H=h+tan α 2 × (S1+S) ± tan α 1 × (S1+S) of ultrahigh column,
Top of ultrahigh column level measurement is complete.
The elevation of top of ultrahigh column when this specification accompanying drawing 1 is higher than B point prism for relief h
H=h+tan α 2 × (S1+S)-tan α 1 × (S1+S).
The elevation of top of ultrahigh column when this specification accompanying drawing 2 is less than B point prism for relief h
H=h+tan α 2 × (S1+S)+tan α 1 × (S1+S).
