PACKER FOR GROUND REINFORCEMENT AND GROUND REINFORCEMENT METHOD USING THE SAME
According to the present invention, a packer (100) for a ground reinforcement material is suggested. The packer includes: a front support member (110) including a core through hole (111) and an injection tube through hole (112) formed in a core part; a lateral support member (120) extended to the rear side of the front support member (110) to be combined with the front support member (110) such that a storage space for an injection tube and a core (200) is formed internally; an expandable pocket (130) wherein an inlet part (131) is located around the edge of the front support member (110), body parts (132, 133) surround an inner surface, an outer surface and a rear end of the lateral support member (120), and the rear side of the lateral support member (120) is opened; and a first expansion pack (141) and a second expansion pack (142) storing first and second materials, which are expanded and hardened when meeting each other, respectively. The inlet part (131) of the expandable pocket (130) is closed in a state in which the first expansion pack (141) and the second expansion pack (142) are stored in the body parts (132, 133) of the expandable pocket (130), and the first and second materials are mixed with each other and expanded and hardened when the first expansion pack (141) and the second expansion pack (142) burst. Thus, the expandable pocket (130) is expanded to press an inner wall of a bored hole (1). Therefore, construction can be convenient because there is no need to transport a heavy urethane injector to a working position, and an effect of closing a bored hole of a packer and the quality of pressure grouting can be reliable.
본 발명은 심부에 심재 관통공(111) 및 주입관 관통공(112)이 형성된 전방 지지부재(110); 상기 전방 지지부재(110)의 후방으로 연장형성되어, 내부에 심재(200) 및 주입관의 수용공간이 형성되도록, 상기 전방 지지부재(110)에 결합한 측방 지지부재(120); 입구부(131)가 상기 전방 지지부재(110)의 가장자리를 둘러 위치하고, 몸통부(132,133)가 상기 측방 지지부재(120)의 내면, 외면 및 후단을 둘러싸며, 상기 측방 지지부재(120)의 후방이 개방되도록 설치된 팽창주머니(130); 서로 만나면 팽창 및 경화하는 제1 재료 및 제2 재료가 각각 수납된 제1 팽창팩(141) 및 제2 팽창팩(142);을 포함하고, 상기 제1 팽창팩(141) 및 제2 팽창팩(142)이 상기 팽창주머니(130)의 몸통부(132,133) 내에 수납된 상태에서 상기 팽창주머니(130)의 입구부(131)가 폐쇄되고, 상기 제1 팽창팩(141) 및 제2 팽창팩(142)이 터지면 상기 제1 재료 및 제2 재료가 서로 혼합되어 팽창 및 경화함에 따라, 상기 팽창주머니(130)가 팽창하여 천공홀(1)의 내벽을 압착하는 것을 특징으로 하는 지반 보강재용 패커(100)를 제시함으로써, 작업위치까지 고중량의 우레탄 주입장치를 운반할 필요가 없어 시공이 편리하고, 패커의 천공홀 폐쇄효과 및 가압 그라우팅의 품질을 신뢰할 수 있도록 한다.
