Description
Technical Field
The utility model relates to a novel control point mark belongs to engineering survey technical field.
Background
The measurement control point is that before the measurement operation, a series of point marking marks are arranged in the area range to be measured to complete the measurement operation of the whole area, and when the point is selected, the existing topographic map of the measurement area and the result material of the control point are firstly investigated and collected.
The measurement is divided into coordinate measurement and elevation measurement, and during measurement, the bottom of the measuring tool is placed on the control point mark.
The traditional control point mark is in a cross pin form, because the bottom of the coordinate measuring device is in a conical pointed shape, no deviation exists when coordinate measurement is carried out in the form, but when elevation measurement is carried out, because the bottom of the elevation measuring device is in a flat shape, the measurement error of the elevation can be increased due to the problem of placement.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a novel control point mark, its concrete technical scheme as follows:
the utility model provides a novel control point marks, marks and elevation including concrete foundation, coordinate, the coordinate mark includes sighting rod I, sighting rod I top is provided with the marking disk, marking disk upper surface central point puts and is provided with mark cap I, it has cross recess to open at mark cap I top center, the elevation marks and includes sighting rod II and the mark cap II that sets up at sighting rod II top, mark cap II top is the horizontal stand form, and inside sets up the spirit level, sighting rod I and sighting rod II coplane and parallel arrangement are in the concrete foundation.
Furthermore, marker post I and marker post II are close the bottom and have seted up threaded through hole in same radial, and marker post I and marker post II are connected through the screw rod that passes threaded through hole to it is fixed through the fixation nut of threaded through hole both sides.
Further, the level meter is internally provided with air bubbles.
Furthermore, the top and the bottom of the concrete foundation are parallel planes, and the bottom of the mark cap I is in contact with the top of the concrete foundation.
The utility model has the advantages that: the utility model discloses a control point marks both integratively, and the UNICOM sets up, has higher stability, and the inside spirit level of elevation control mark can detect whether elevation control mark itself takes place to incline on the one hand, and on the other hand also can reflect coordinate control point's change, effectively reduces the measuring error influence that the problem was brought in the sopwith staff measurement process.

Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
Example (b):
as shown in figure 1 and figure 2, the utility model discloses a novel control point mark, including concrete foundation 1, coordinate mark 2 and elevation mark 3, coordinate mark 2 includes sighting rod I2-1, sighting rod I2-1 top is provided with sighting disk 2-2, the central point of surface is provided with sighting cap I2-3 on sighting disk 2-2, sighting cap I2-3 top center is opened has cross recess 2-4, elevation mark 3 includes sighting rod II3-1 and sets up sighting cap II3-2 at sighting rod II3-1 top, sighting cap II3-2 top is the horizontal bench form, inside sets up spirit level 6, sighting rod I2-1 and sighting rod II2-2 vertical setting are in concrete foundation 1.
The top and the bottom of the concrete foundation 1 are parallel planes, and the bottom of the mark cap I2-3 is in contact with the top of the concrete foundation 1.
The level gauge 6 adopts a bubble level gauge, a marker post I2-1 and a marker post II3-1 are close to the bottom and are provided with a threaded through hole 8 in the same radial direction, and the marker post I2-1 and the marker post II2-2 are connected through a screw rod 4 penetrating through the threaded through hole 8 and are fixed through fixing nuts 5 on two sides of the threaded through hole 8.
When the measuring device is used, the air bubbles 7 in the level gauge 6 are observed, the control mark is adjusted to be horizontal, the tip of the lower part of the prism is aligned to be placed in the cross-shaped groove 2-4 for coordinate measurement, then the bottom of the tower ruler is placed on the top plane of the mark cap II3-2 for elevation measurement.
In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
