この発明は、岩石の切断方法、特に、狭い場所で岩石を
切断する岩石の切断方法に関する。DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a rock cutting method, and particularly to a rock cutting method for cutting rock in a narrow space.
（従来の技術）
従来、土木建設現場等で穴の掘削中或いは、溝の開削中
に岩石に突き当った場合、この岩石を切断して更に掘り
進むか、或いは、この岩石全体を取り除いて更に掘り進
んでいた。(Prior art) Conventionally, when a rock is encountered while excavating a hole or trench at a civil engineering construction site, the rock has to be cut off and the excavation continued, or the entire rock has been removed and the excavation carried out further. It was progressing.
しかし、前者の方法では、穴内で、たがねや、やに玄翁
を振り上げて切断作業するには狭く、また、切断は必ず
しも垂直に割れるとは限らず、下方に進むに従って拡が
るようなテーパ状に割れた場合、切断された岩石の取り
出しが困難であり、さらに細かく割って取り出すため作
業効率が極めて悪いものであった。However, with the former method, it is too narrow to swing a chisel or chisel up in the hole for cutting, and the cut does not necessarily result in vertical cracks, but instead creates a tapered shape that widens as it goes downward. When the rock is broken into pieces, it is difficult to remove the cut rock, and the work efficiency is extremely low because it has to be broken into smaller pieces.
また、後者の場合、工事請負の範囲を超えて大きな穴（
岩石が完全に取り除けるだけの直径を有する穴）を掘る
ため、採算が採れない場合があった（発明が解決しよう
とする問題点）
そこでこの発明は、上記の欠点を除去し、狭い穴内でも
作業が楽に行へ、切断された岩石の取り出しが簡弔であ
り、作業効率の優れた岩石の切断方法を提供するもので
ある。In the latter case, large holes (
This invention eliminates the above disadvantages and makes it possible to work even in narrow holes. The present invention provides a rock cutting method that allows for easy handling, easy removal of cut rocks, and excellent work efficiency.

On the cutting line of rock (1), holes (
2), and between these holes (2) (2), the hole has a width that is approximately the same as the diameter of the hole, a vertical width that is approximately the same as the length between the holes, and a hole at the tip. Multiple chevron-shaped cutting edges (
3a) is removably attached to a hammer device (4) such as a breaker, and the cutting blade (3) is aligned on the same line as the cutting line and in the axial direction of the hole (2). Cut at an appropriate angle, then cut from the opposite direction,
This operation is repeated to sequentially cut between the holes (2) (2).

である等の効果を奏する。(Effects of the Invention) According to the present invention, holes (2) of appropriate diameters are provided at predetermined intervals on the cutting line of the rock (1), and there are holes between these holes (2). , a cutting blade (3) having a width that is approximately the same as the diameter of the holes, a vertical width that is approximately the same as the length between the holes, and a plurality of chevron-shaped cutting edges (3a) at the tip.
In order to use the chevron-shaped cutting edge, the cutting starts with the edge of the chevron, and then is guided to the holes (2) and (2), so it does not break in different directions, and the width of the cutting line is the same as the hole (2). ) and the width of the cutting blade (3), making it easy to take out rocks.
), making it easy to work in narrow holes and work efficiently.Of course, it can also be used to cut exposed rocks, garden stones, etc., compared to the conventional method of burning and cutting. Like a stone, it never becomes unusable and has extremely beneficial effects.
