Description

The present invention is an instrument used during landfill installation work of the boundary pile 4 in civil engineering work or the like.

Conventionally, the boundary pile 4 is landfilled by positioning with a thread and weight through a tripod.

There was a difficulty in positioning due to the shaking of the weight due to wind or the like, and the boundary pile 4 could not be landed vertically but was inclined and landed.

The landfill pile 4 is positioned at the irradiation point 3 by the light source 2 of the semiconductor laser 1. At the time of reclamation work of the boundary pile 4, the irradiation point 3 has a light beam from the light source 2 on a straight line, and the distal end portion and the ground surface side of the boundary pile 4 have the same irradiation point 3.

The present invention is an instrument having a base 5, a column 7, an arm 13, and a semiconductor laser fixing jig 16 that holds the light source 2 of the semiconductor laser 1 without shaking.

The structure is composed of a column 7 standing vertically on a pedestal 5, an arm 13 installed horizontally on the pedestal 5, and a semiconductor laser 1 such as a laser pointer and a semiconductor laser fixing jig 16 on the arm 13.

Regardless of the fluctuation of the weight due to the conventional wind, there is no difficulty in positioning because of the irradiation point 3 of the light beam from the light source 2 of the semiconductor laser 1, and the tip and the ground surface side of the boundary pile 4 can be irradiated simultaneously.

First, the hole 18 is dug with a scoop, and the tip of the boundary pile 4 is inserted into the position of the irradiation point 3 at the bottom of the hole 18 to fill the soil. It is confirmed that the soil is continuously buried and the irradiation of the irradiation point 3 is performed on the ground surface side of the boundary pile 4. At this time, the boundary pile 4 is buried vertically on the ground.

When the semiconductor laser fixing jig 16 and the arm 13 of the light source 2 are obstructed when the hole 18 is dug in the ground with a scoop or the like, the arm 13 is swung around the pillar 7 to a position where it does not get in the way.

Is a perspective view of the present invention. FIG. 1 is a perspective view showing an embodiment of the present invention. FIG. 3 is a perspective view showing the implementation of the present invention.

The present invention is divided into a pillar 7, an arm 13, a semiconductor laser fixing jig 16, and a semiconductor laser 1 attached to the base 5.

Assemble as shown in Fig. 1 at the local workshop.

At this time, a level is applied to the pedestal 5 and the level is maintained with the leveling screw 6.

Hereinafter, it demonstrates with drawing. The arm 13 is turned toward the mark position positioned on the ground, and is tightened with the column turning stop screw 9. The semiconductor laser fixing jig 16 in contact with the arm 13 and the groove 15 is slid, the irradiation point 3 of the light source 2 of the semiconductor laser 1 is aligned with the mark position, and the jig fixing screw 17 is tightened.

An arm turning stop plate 14 connected to the arm 13 is aligned with the stopper 12 of the arm positioning plate 10 of the turning column 8 attached to the arm 13 and fixed with the arm positioning screw 11.

Even if the arm 13 is turned and then returned to its original position, the irradiation point 3 irradiates the original position at the mark position determined first, and the boundary pile 4 can be easily confirmed after being landfilled.

The conventional landfill pile 4 work was done by two people, but in the implementation of this draft, the worker can work alone and the work time is shortened.

By removing the semiconductor laser 1 from the instrument of the present invention and attaching a surveying pole or prism mirror to this location, it is possible to survey the distance by yourself using a surveying instrument.
