즉, 도 5에서와 같이 상기 바이브레이터의 일단을 크레인의 고리에 걸림 고정시킨 상태에서, 상기 바이브레이터의 결속기구를 상기 오버랩 원통관(400)의 상측에 결속시킨 후, 상기 바이브레이터에 케이블을 통해 전원을 인가하면, 상기 바이브레이터는 결속기구를 통해 상기 오버랩 원통관(400)을 인발시, 상기 오버랩 원통관(400)은 인발시 진동될 수 있는 것이다. That is, after binding the binding mechanism of the vibrator to the upper side of the overlap cylindrical tube 400 in a state in which one end of the vibrator is caught and fixed to the ring of the crane as shown in FIG. 5, power is supplied to the vibrator through a cable When applied, when the vibrator draws out the overlap cylindrical tube 400 through the binding mechanism, the overlap cylindrical tube 400 may vibrate during drawing.

이때, 상기 바이브레이터가 상기 오버랩 원통관(400)에 진동을 부여하면서 상기 오버랩 원통관(400)을 제 1 방향으로 적어도 한번 이상 상승(예; 5m 상승) 및 일시 멈춤시킨 다음, 상기 제 1 방향과 반대되는 제 2 방향으로 상기 오버랩 원통관(400)을 눌림 다짐(예; 1m 하강)하는 진동 및 인발 공정을 수회 반복 실시한다.At this time, while the vibrator applies vibration to the overlap cylindrical tube 400, the overlap cylindrical tube 400 rises at least once in the first direction (eg, rises by 5 m) and temporarily stops, and then in the first direction and The vibration and drawing processes of pressing and compacting the overlap cylindrical tube 400 in the opposite second direction (eg, descending by 1 m) are repeated several times.

일예로, 상기 오버랩 원통관(400)이 약 20m의 길이인 경우, 상기의 상승과 일시 멈춤 및 눌림 다짐의 공정을 6∼7회 정도 반복 실시하는 것이다.For example, when the overlap cylindrical tube 400 has a length of about 20 m, the process of raising, stopping, and pressing is repeatedly performed 6 to 7 times.

그러면, 상기 오버랩 원통관(400)의 내부 타설 영역(S1, S1')에 타설된 차수벽 형성물질인 상기 콘크리트(700)가 상기 오버랩 원통관(400)의 설치 단면 외측에 존재하는 외측 원통관(300)의 제거 영역인 확산 영역(S2, S2')까지 확산될 수 있게 되는 것이다.Then, the concrete 700, which is an order wall forming material poured into the inner pouring regions S1 and S1' of the overlap cylindrical tube 400, is located outside the installation cross-section of the overlap cylindrical tube 400. The outer cylindrical tube ( It is possible to diffuse to the diffusion regions S2 and S2', which are the removal regions of 300 .

이때, 상기 오버랩 원통관(400')의 내부 타설영역(S1')으로 타설되는 상기 콘크리트(700)가 확장영역(S2')으로 확장시, 상기 확장 영역(S2')은 이웃하는 오버랩 원통관(400)의 원호면(401)에 밀착되면서, 상기 오버랩 원통관(400, 400')의 내부로 타설된 콘크리트(700)를 이루는 모래와 자갈층의 다짐 밀도는 상기 오버랩 원통관(400)이 진동하면서 인발시 강화되고, 동시에 이웃하는 상기 확장영역(S2, S2')사이에 선등록특허와 같이 별도의 충진용 호스 설치를 통해 충진재를 충진시키지 않더라도 차수벽을 이루는 콘크리트 말뚝(기둥)의 단면 확장이 이루어지면서 연속적이고도 안정적인 차수 효과를 가진 흙막이 차수벽 시공이 완료될 수 있게 되는 것이다.At this time, when the concrete 700 poured into the inner pouring area S1' of the overlap cylindrical tube 400' is expanded to the extended area S2', the expanded area S2' is a neighboring overlap cylindrical tube. The compaction density of the sand and gravel layers constituting the concrete 700 poured into the overlap cylindrical tubes 400 and 400 ′ while being in close contact with the arc surface 401 of the 400 , the overlap cylindrical tube 400 vibrates. The cross-section of the concrete piles (pillars) forming the order wall is reinforced while drawing out, and at the same time, the cross-section of the concrete piles (pillars) forming the order wall is expanded even if the filler is not filled through the installation of a separate filling hose as in the previously registered patent between the adjacent extension areas (S2, S2'). As such, the construction of a retaining barrier wall with a continuous and stable water blocking effect can be completed.
