In order to make the basement or the basement of the building, excavation work is performed to dig a ground in a predetermined shape.

Generally, the excavation works of the ground are performed by using an excavator, a hammers or a ground excavator to press the H beam or the cylindrical foundation pile into the ground.

The ground excavator that presses the H beam or the cylindrical foundation file into the ground is supported by the crawler traveling device, crawler traveling device support, backstage, vertically fixed leader, An auger machine installed in the auger machine, and a rod vertically stacked on the auger machine.

In such a conventional ground excavation apparatus, after the crawler traveling apparatus is supported and fixed on the ground by the support of the crawler traveling apparatus, an auger machine is positioned in the air by a reader, and an H beam or a cylindrical foundation file is placed on the ground And excavated.

As described above, in the conventional ground excavation apparatus, excavation work proceeds in a state where the crawler traveling apparatus is supported and fixed on the ground. Therefore, an excavation depth error is generated for each excavation position according to a change in the height of the ground surface or a tilt state .

Therefore, it is inconvenient to measure the excavation depth at least once or twice every excavation position during excavation work.

Particularly, in the ground excavation process of the ground excavation equipment according to the related art, since the excavation depth measurement information can not be confirmed in real time, after the excavation operation of the ground excavation equipment is stopped, a user or a separate manager has to measure the excavation depth.

In this way, the drilling operation is interrupted for each period of measuring the excavation depth, and then the excavation operation must be repeatedly performed again.

In addition, when the depth of excavation is measured, it is difficult to confirm the scale of the excavation depth measurement equipment, so that the error rate is high. Therefore, calculation must be carried out separately considering the height and slope of the ground with the excavation depth measurement value. There is a further problem that it is lowered.
