Description
Technical field
The utility model is related to a kind of applied to the high-precision levelings such as highway, railway, municipal engineering construction construction neck
The measurement of the level Sopwith staff in domain.
Background technology
In the engineering construction construction measurement of the level, for the tested point measurement of higher degree, it is necessary to use levelling rod.Levelling rod is adaptation
Different measurement of higher degree scopes, generally using tower stretch mode, provided with multiple sections being socketed successively, pass through spring button control
Each section is flexible and positions, and realizes levelling rod adjustable length.During measurement, levelling rod is stood on tested point, appropriate length is adjusted to
Degree, scale reads the reading on levelling rod, and calculate the elevation of tested point facing to spirit level by spirit level.Preferable shape
Under state, when vertical chi is completely vertical with horizontal plane, the data that spirit level is measured are most accurate.But in concrete operations, Sopwith staff and level
The perpendicularity in face always has certain error, therefore the point data to be measured that spirit level is measured also has certain error.Although can be in tower
Level(l)ing bubble is set on chi to improve vertical chi precision, but level bubble can only also do one roughly in practical operation,
Still error can not be completely eliminated.For required precision very high measurement operation, the method used at present is to carry out multiple repetition measurement,
At least 3 group number-readings are obtained, and COMPREHENSIVE CALCULATING is carried out to 3 group number-readings by certain algorithm, effectively to reduce due to levelling rod
Measurement error caused by vertical chi deviation.But existing levelling rod is generally slab construction, a scale face is provided only with, is once stood
Chi, spirit level can only obtain a reading.Therefore repeatedly repetition measurement is accomplished by repeatedly manually vertical chi, cause measurement efficiency of construction compared with
It is low.
The content of the invention
The utility model is directed to levelling rod in existing technical levelling and founds the problem of chi error bad control there is provided one kind
Measurement of the level construction is with three face scale levelling rods, by improving levelling rod model and observation procedure, and the vertical chi for reducing levelling rod will
Ask, and improve engineering mapping precision, can also effectively simplify the repeated measurement operation in measurement process, so as to greatly improve
The operating efficiency of engineering mapping.
The technical solution of the utility model is as follows：
A kind of measurement of the level T-shaped telescopic Sopwith staff, including chi frame, it is characterised in that：The cross section of the chi frame is T
Type, is longitudinally respectively equipped with scale along 3 planes with direction towards unidirectional plane with 3, forms the first scale
Chi, the second graduated scale and the 3rd graduated scale.
The utility model is simple in construction, conveniently moving, mobility strong, can effectively eliminate traditional levelling rod in measurement process
The error in reading caused by vertical chi deviation.The utility model once founds chi, spirit level provided with 3 scale faces in measurement operation
Just 3 group number-readings can be obtained, and the Precision Elevation data for meeting code requirement are calculated by 3 group number-readings, are avoided that substantial amounts of
Repetition measurement works, the efficiency of lifting measurement operation, also reduces the requirement of vertical chi, and can significantly improve the precision of measurement.
Brief description of the drawings
Fig. 1 is top view of the present utility model；
Fig. 2 is elevation of the present utility model, shows 3 towards unidirectional graduated scale；
Fig. 3 is enlarged drawing at A in Fig. 2.
Embodiment
As shown in Fig. 1, Fig. 2, Fig. 3, the utility model includes chi frame 1, and the cross section of the chi frame 1 is T-shaped, with 3
Towards unidirectional plane, scale is longitudinally respectively equipped with along 3 planes with direction, the first graduated scale 2, the second scale is formed
The graduated scale 4 of chi 3 and the 3rd.
The utility model in chi frame upper end when it is implemented, to improve vertical chi precision, can set level(l)ing bubble 5.
The utility model is used when being high-acruracy survey, and Sopwith staff design length is 3~5m；Carry and use for convenience, can
Sopwith staff is set to tower stretching structure, including at least three slides the section of suit successively, and in two relative sides of chi frame
Upper end set respectively control section sliding extension spring button 6, stretching structure compared with plate Sopwith staff it is identical, using
When facilitate section flexible and position.When tested point position is relatively low, Sopwith staff can be elongated, otherwise Sopwith staff can be shortened, make single
Measurement of higher degree scope is greatly improved.
Scale on each graduated scale of the utility model is the same with traditional plate levelling rod scale.To distinguish three not
The reading of coplanar graduated scale, 3 graduated scales can select three kinds of different colors.
The utility model is in use, vertical chi method is similar to traditional leveling measuring method, according between landform and tested point
Relation, select suitable position to set up spirit level on construction ground, and by code requirement leveling spirit level；Find tested point,
The fixed vertical chi on tested point, and make three scale faces of the present utility model just to spirit level；Read in order by spirit level
The reading and record of first graduated scale, the second graduated scale and the 3rd graduated scale, are easy to algorithmically carry out Precision Elevation calculating.
The utility model, which once founds chi, just can obtain calculating 3 groups of data of tested point Precision Elevation value, it is to avoid repeat
Vertical chi, effectively simplifies measurement process, greatly improves the operating efficiency of engineering survey.
