After temporarily attaching with adhesive, a non-return valve (10) connected with a ground anti-sedimentation agent and a hose for supplying a waterproofing agent (not shown) is installed at a predetermined interval under the nonwoven fabric sheet (7). Attached nonwoven bags (9) (9 ') ... and arranged at said intervals, beams (8) are installed on the attached nonwoven bags (9) (9') ... and the beams (8) And the upper end 8 ′ of the beam 8 by welding with the iron plate 11, and then filling each beam and the beam with the bracing plate 12 to form a supporting wall for the underground structure, and the nonwoven plate 7 and the nonwoven fabric sac (9) In the space (13) between the (9 ') and the iron plate (11), a check valve (14) installed through the iron plate (11) and the crutch (12) and connected to an external hose for injecting a waterproofing agent and antisettling agent is installed. Then, during the excavation of the ground while pushing the excavator 4, the rear end 19 of the inner cylinder inner working cylinder cylinder 16, which is mounted to the rear of the outer excavator cylinder 15, is extended and finally installed. In the state of touching the beam 8, the excavator inner working cylinder cylinder 16 is continuously extended so that the rear working cylinder 3 of the excavator 4 sequentially moves out of the beams 8 installed therein, and the hoses The overflow check valves (10) and (14) are connected so that the fat antisettling agent and the waterproofing agent are filled completely with the nonwoven bag (9) (9 ') and the space (13) and overhole (18). It is composed of hardening after filling to form settlement prevention groundwater prevention wall.
이상에서 버팀판은 통상의 프리케스팅 콘크리트(PC), 철근 콘크리트, 각목, 철판등으로된 것중에서 선택되고 지반 침하방지겸 방수제는 통상의 벤트나이트, 시멘트를 물과함께 혼련한 것으로 한다.In the above, the prop plate is selected from the group consisting of ordinary precast concrete (PC), reinforced concrete, lumber, iron plate, etc., and ground subsidence prevention and waterproofing agent are kneaded with normal bentite and cement together with water.
이상과 같이 구성되는 지하구조물의 지반 침하방지 및 방수벽 설치방법에 의하여 지하구조물을 설치하므로서 부직포판(7)과 부직포낭(9)(9')에 방수제겸 지반 침하방지제가 주입 침투되고 부직포판(7), 부직포낭(9)(9') 및 빔(8)과 빔(8)의 상단(8')을 연결하여 용접한 철판(11) 사이의 공간(13)과 여굴에도 지반 침하방지제겸 방수제가 순간적으로 완전히 차도록 채워져서 경화되므로써 지반 침하방지겸 지하수 유출방지벽이 형성되어 완벽하게 지반의 침하방지는 물론 지하수 유출도 완벽하게 방지할 수가 있게 되게되므로 지하구조물 설치공사를 쾌적한 상태에서 용이하게 효과적으로 단시간에 많은 공사를 할 수 있게된다.The waterproofing and ground subsidence are injected into the nonwoven fabric 7 and the nonwoven fabric 9 and 9 'by installing the underground structure according to the ground subsidence prevention and waterproof wall installation method of the underground structure configured as described above. (7), non-woven sacks (9) (9 ') and ground (13) between the steel plate (11) welded by connecting the beam (8) and the upper end (8') of the beam (8) and ground subsidence As the preventive agent and the waterproofing agent are filled to be completely filled at once, it is hardened by the ground subsidence prevention and groundwater outflow prevention wall to be completely prevented from subsidence of the ground and the groundwater outflow. Easily and effectively, a lot of construction can be done in a short time.
본 발명 지하구조물의 지반 침하방지 및 방수벽 설치방법에 의해 지하구조물의 방수 및 침하방지벽을 설치한후 구조물 시설공사를 하게되면 지반의 침하나 지하수 유출이 전혀없으므로 작업이 용이하고 따라서 단시간에 효율적으로 많은 양의 공사를 완료할 수 있는 효과가 있다.According to the present invention, after installing the waterproofing and subsidence prevention wall of the underground structure by installing the waterproofing and subsidence prevention wall of the underground structure, there is no settlement of ground or leakage of groundwater, so the work is easy and therefore efficient in a short time. As a result, a large amount of construction can be completed.
