DUST RECOVERY SYSTEM
PROBLEM TO BE SOLVED: To secure high safety and workability by preventing scattering of dust during drilling.SOLUTION: A drilling method according to an embodiment is used to form a hole in a roof material. The drilling method is characterized as follows: a foundation hole with a predetermined depth smaller in dimension than thickness of the roof material is formed; a wet material is supplied to the foundation hole; and the foundation hole is drilled through a part with rest of the thickness after supply of the wet material.SELECTED DRAWING: Figure 1
【課題】穿孔時の粉塵飛散を防止し、高い作安全性や作業性を確保する。【解決手段】実施形態にかかる穿孔方法は、屋根材に孔を形成する穿孔方法であって、前記屋根材の厚みより小さい所定深さの基礎穴を形成し、前記基礎穴に湿潤材を供給し、前記湿潤材の供給後に前記基礎穴の残り厚を貫通させる、ことを特徴とする。【選択図】図１
