Abstract
The utility model discloses a kind of teaching surveyor's table, relate to civil engineering teaching apparatus field, this teaching surveyor's table comprises the orthogonal base chi and parallel rule that are arranged on bottom, telescope is provided with above this surveyor's table, observation position above telescope is provided with mark telescope, telescopical side is provided with discoidal altitude circle, the front of altitude circle is fixed with air level, design is accurate, simple to operate, fully can show principle and the effect of surveyor's table, be suitable for civil engineering mapping practical teaching and use.
Description
Technical field
The utility model relates to civil engineering teaching apparatus field, particularly one teaching surveyor's table.
Background technology
Planetabling is by ground object, and scaled rear direct mapping is on drawing.In measurement, because the horizontal projection of angle and straight line is all diagrammatically try to achieve, therefore be called again diagram measurement.And at present in the middle of practical application, surveyor's table progressively by total powerstation and GPS-RTK digitized mapping replace.Professor's basic measurement knowledge is usually used in the middle of teaching.
Existing surveyor's table does not have the special type its principle of work being explained to design, in teaching process, is often difficult to get across its course of work with student.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of teaching surveyor's table, by design air level, altitude circle and mark telescope, to solve the too simple defect of existing surveyor's table.
For achieving the above object, the utility model provides following technical scheme: a kind of teaching surveyor's table, it is characterized in that: described teaching surveyor's table comprises the orthogonal base chi and parallel rule that are arranged on bottom, telescope is provided with above this surveyor's table, observation position above telescope is provided with mark telescope, telescopical side is provided with discoidal altitude circle, and the front of altitude circle is fixed with air level.
Preferably, described telescope is optical telescope.
Preferably, described mark telescope is provided with telemeter rod.
Preferably, described air level is round metal bubble.
Preferably, described altitude circle is formed by stainless steel manufacture.
The beneficial effect of above technical scheme is adopted to be: this teaching surveyor's table comprises the orthogonal base chi and parallel rule that are arranged on bottom, telescope is provided with above this surveyor's table, observation position above telescope is provided with mark telescope, telescopical side is provided with discoidal altitude circle, the front of altitude circle is fixed with air level, and design is accurate, simple to operate, fully can show principle and the effect of surveyor's table, be suitable for civil engineering mapping practical teaching and use.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Fig. 1 is that a kind of teaching of the utility model uses the structural representation of surveyor's table.
Wherein, 1-base chi, 2-parallel rule, 3-telescope, 4-air level, 5-altitude circle, 6-mark telescope.
Embodiment
Describe a kind of teaching of the utility model in detail below in conjunction with accompanying drawing and use the preferred implementation of surveyor's table.
Fig. 1 shows that the utility model is a kind of imparts knowledge to students by the embodiment of surveyor's table: this teaching surveyor's table comprises the orthogonal base chi 1 and parallel rule 2 that are arranged on bottom, telescope 3 is provided with above this surveyor's table, observation position above telescope 3 is provided with mark telescope 6, the side of telescope 3 is provided with discoidal altitude circle 5, and the front of altitude circle 5 is fixed with air level 4.
Telescope 3 is optical telescope, and mark telescope 6 is provided with telemeter rod, and air level 4 is round metal bubble, and altitude circle 5 is formed by stainless steel manufacture.
The course of work of this teaching surveyor's table: (1) centering, makes the survey station corresponding on ground of the known point on drawing point be positioned on same pedal line; (2) flatten, the base chi 1 on chart board and surveyor's staff 2 are horizontal; (3) directed, the direction line making the known direction line on drawing corresponding on ground is consistent or parallel.By ground object, scaled rear direct mapping on drawing, then surveys and draws out planimetric position and the elevation of geomorphological features unique point on drawing according to the principle of similitude, and describes topomap with these points.
Above is only preferred implementation of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
Claims (5)
