Abstract

(57) [Summary] [Purpose] During surveying, enable the pin pole with a reflecting prism to be set up in the correct posture even if there are structures up to the boundary pile. [Structure] An indicator plate (1) and a set screw (3) are attached to a pin pole sandwiching portion (2).

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a pin pole used for optical wave survey.

[0002]

[Prior art]

When surveying, if there is a structure up to the boundary pile, the pin pole with reflecting prism cannot stand on the boundary point due to its own thickness. As a supplement to this, a corner adapter is commercially available. (Refer to the drawing below.) This is integrated with the reflection prism, and the adapter can be fitted to the boundary point to enable direct measurement. However, in order to collimate the lower boundary pile, the lightwave generator must be tilted down. Since the reflecting prism is orthogonal to the light wave, we want to face it upward, but the thickness of the adapter hits the structure and cannot tilt it. In addition, the reflection prism fixed to the adapter is inflexible, and if there is an obstacle on the collimation line, it is impossible to see it at all. Even if this is inserted into the pin pole and lifted up, the fixed reflection prism must be lifted until the incident angle is within 5 ° (error occurs for 5 ° or more). The verticality of the pin pole at that time is not guaranteed.

[0003]

[Problems to be Solved by the Invention] In order to solve the above-mentioned drawbacks, the present invention aims to secure a correct surveying posture by attaching a surveying pin pole adapter to the pin pole.

[0004]

[Means for Solving the Problems]

 An indicator plate (1) and a set screw (3) are provided on the pin pole sandwiching portion (2). This proposal has the above configuration.

[0005]

[Action]

 Insert the pin pole clip (2) into the leg of the survey pin pole (4), and fix it with the set screw (3). Since the reflecting prism that can change its direction freely and the boundary point indication part are separated, the reflecting prism can be moved up and down and left and right as before, and it can also be made orthogonal to the light wave, and most of it is on the collimation line. The obstacles can be avoided.

[0006]

【Example】

A description will be given below based on examples. Align the tip of the indicator pin (1) of the survey pin pole set as described above with the boundary point. Then, the direction of the reflecting prism is moved so as to be aligned with the collimation line of the theodolite (light wave generator). The angle is the pin pole core, and the length is the measured distance (L) by adding the constant of the indicator plate length (l ₁ ) to the reading value of the light wave range finder.

[0007]

[Effect of device]

 The present invention attempts to measure the direct angle and the distance by installing the reflection prism and the surveying pin pole adapter separately, without obstructing obstacles up to the boundary point and short obstacles on the line of sight. It is a thing.
