Claims (1)
- 대상암반에 소정의 직경(D)과 길이(H)로 구멍에 이 구멍 길이의 절반(H/2)에 해당하는 만큼의 아래쪽에 유체가 채워진 튜브(3)를 삽입설치하고, 이 유체튜브(3)위에 폭발수단을 삽입설치한 후, 이 폭발수단위에 미리 소정의 직경과 폭을 갖도록 만들어져 내부에 충격흡수재가 충전된 여러개의 충격흡수유니트(10)를 설치하며, 이 충격흡수유니트위(10)에 접착력이 큰 밀봉재(11)를 충전시켜 상기 구멍을 밀봉시킨 다음, 상기 폭발수단을 점화.폭발시켜 그 폭발력과 함께 상기 튜브속에 채워진 액체(F)가 팽창하는 힘으로 암반을 파쇄하도록 된 무진동암반발파공법에 있어서, 유연성이 있는 튜브(5)속에 폭발성개스(4)가 가압 충전되어 패키지화된 폭발수단을 전기적으로 점화.폭발시켜 얻어지는 폭발력으로 상기 유체튜브(3)속에 채워져 있는 유체(F)를 가압.팽창시켜 주도록 된 것을 특징으로 하는 무진동암반발파공법.※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
