Apparatus for shielding high depth groundwater well prevention grouting

CHO HEUY NAM / CHOI SUNG OUK / PARK SANG GIN

A shielding apparatus for high-depth groundwater well pollution prevention grouting of the present invention comprises: a shielding part which is provided on an outer circumferential surface of a grouting casing installed in an excavation hole in the ground and compressed to be in close contact with a hollow wall of the excavation hole; a compression part which is installed on the outer circumferential surface of the grouting casing, is formed to descend toward the shielding part, and brings the shielding part to be in close contact with the hollow wall of the excavation hole to guide the excavation hole to be sealed; and a pressure equalization injection tube part which is connected with the compression part on the outer circumferential surface of the grouting casing and lowers the compression part by water pressure generated by supplying water from the outside through a water supply tube.

본 발명은 지중의 굴착공 내부에 설치되는 그라우팅 케이싱의 외주면에 구비되고, 상기 굴착공의 공벽에 밀착되도록 압축되는 차폐부와, 상기 그라우팅 케이싱의 외주면에 설치되고, 상기 차폐부를 향해 하강하도록 형성되며, 상기 차폐부를 상기 굴착공 공벽에 밀착시켜 상기 굴착공을 밀봉하도록 가이드 하는 압착부 및 상기 그라우팅 케이싱의 외주면에서 상기 압착부와 연결되며, 물 공급관을 통해 외부로부터 물이 공급됨에 따라 발생되는 수압에 의해 상기 압착부를 하강시키는 균압 주입관부를 포함한다.
