Therefore, it is necessary to design a simple observation device.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to design a sectional measuring device of road bed that can dynamic adjustment, the adjustable record of developments through the device realization road bed section observation point is measurationed.
In order to realize the technical purpose, the utility model adopts the technical scheme that the measuring device for the observation point of the roadbed section comprises a square rod 1, a tripod 2, a square groove 3, a U-shaped connecting arm 4, a ruler 5 and an observation hole 6;
the top of the square rod 1 is provided with a square groove 3, and the square groove 3 is a through hole structure on the front side (namely the observation surface facing the roadbed) and the back side of the square rod 1; the side surface of the square rod 1 is provided with a vertical side surface groove which is communicated with the square groove 3; the bottom of the square rod 1 is provided with a tripod 2; the straight ruler 5 is vertically fixed on the top of the square rod 1.
The observation hole 6 is arranged in the square groove 3, and the observation hole 6 can slide in the square groove 3; one end of the U-shaped connecting arm 4 is connected with the observation hole 6, the other end of the U-shaped connecting arm 4 is installed on the ruler 5, and the U-shaped connecting arm 4 is in sliding fit with the ruler 5.
The zero degree line of the straightedge 5 is arranged at the bottom of the straightedge 5.
Compared with the prior art, the utility model discloses following technological effect has.
The utility model relates to a roadbed section observation point measuring device which can effectively measure the roadbed section; when a plurality of continuous measuring points need to be observed, the central positions of the continuous observing points are automatically recorded by adjusting the positions of the observing holes up and down, so that the operation and the use are very convenient, and the cost is lower.
Drawings
Fig. 1 is a schematic structural diagram of the device of the present invention.
Fig. 2 is a schematic cross-sectional view of the device of the present invention.
Detailed Description
The technical solution is described in detail and fully with reference to fig. 1 to 2 of the drawings. It is to be understood that the embodiments described are only some embodiments and not all embodiments. The following description of the embodiments is merely exemplary in nature and is in no way intended to limit the application or uses. All other embodiments obtained by those skilled in the art without any creative work based on the present embodiment belong to the protection scope of the present invention. Meanwhile, the sizes of the respective portions shown in the drawings are not drawn in an actual proportional relationship for convenience of description.
As shown in fig. 1-2, a roadbed section observation point measuring device comprises a square rod 1, a tripod 2, a square groove 3, a U-shaped connecting arm 4, a straight ruler 5 and an observation hole 6;
the top of the square rod 1 is provided with a square groove 3, and the square groove 3 is a through hole structure on the front side (namely the observation surface facing the roadbed) and the back side of the square rod 1; the side surface of the square rod 1 is provided with a vertical side surface groove which is communicated with the square groove 3; the bottom of the square rod 1 is provided with a tripod 2; the straight ruler 5 is vertically fixed on the top of the square rod 1.
The observation hole 6 is arranged in the square groove 3, and the observation hole 6 can slide in the square groove 3; one end of the U-shaped connecting arm 4 is connected with the observation hole 6, the other end of the U-shaped connecting arm 4 is installed on the ruler 5, and the U-shaped connecting arm 4 is in sliding fit with the ruler 5.
The zero degree line of the straightedge 5 is arranged at the bottom of the straightedge 5.
The utility model relates to a roadbed section observation point measuring device which can effectively measure the roadbed section; when a plurality of continuous measuring points need to be observed, the central positions of the continuous observing points are automatically recorded by adjusting the positions of the observing holes up and down, and the operation and the use are very convenient.
Examples
When the section shape of the roadbed needs to be recorded or the roadbed filling area needs to be calculated:
the size of the square rod 1 is 1200mm 25mm (height length width), the height of the tripod 2 is 200mm 260mm, and the size of the square groove 3 is 10mm 400mm (length width); the dimensions of the lateral grooves are 5mm x 400mm (length x width).
The first observation point and the second observation point are both arranged on a cross section which is vertical to the axis direction of the road, and the positions of the two measurement points are on the same vertical plane; the central position of the first observation point observed through the observation hole is set as x1, the position of the observation hole is adjusted by pulling the U-shaped connecting arm 4, the observation hole is aligned with the central position of the second observation point, the position read at the moment is set as x2, then x2 is x1 +/-d, and d is the moving distance of the U-shaped connecting arm 4 on the ruler 5.
Since the zero degree line of the straightedge 5 is arranged at the bottom of the straightedge 5 the distance of moving the U-shaped connecting arm 4 is very easy to read.
In addition, the device can also survey the record that the road bed subsides the observation point, valuable instruments such as total powerstation compare, the utility model discloses simple structure, low cost.
