본 고안은 교각기초 우물통의 수중콘크리트의 구조에 관한 것으로서, 더욱 상세하게는 저반콘크리트 타설전에 그라우팅 파이프를 설치하고 콘크리트 양생후 우물통 하단에 시멘몰탈을 주입한 구조에 관한 것이다.The present invention relates to the construction of underwater concrete in a pier foundation well, and more particularly, to a structure in which grouting pipes are installed before low-bed concrete pouring and cement cement is injected into the bottom of the well after curing concrete.
이하 본 고안의 구조과 시공에 대해서 구체적으로 설명하면 다음과 같다.Hereinafter, the structure and construction of the present invention will be described in detail.
본 고안의 개괄적인 개념은 도 2에서 알 수 있듯이, 우물통 본체콘크리트(20)의 내부 암바닥(10)까지 그라우팅 파이프(50)와 에어배출구(60)가 설치되고, 상기 그라우팅 파이프(50)에 바지선(70)에 탑재된 시멘몰탈 믹서를 이용하여 그라우팅몰탈을 주입하여 시공한다.The general concept of the present invention, as can be seen in Figure 2, the grouting pipe 50 and the air outlet 60 to the inner rock bottom 10 of the well body concrete 20 is installed, the grouting pipe 50 Injecting grouting mortar using a cement mortar mixer mounted on the barge 70 to the construction.
그리고 본 고안의 평면도을 도시한 도 3에서 알 수 있듯이, 우물통 본체콘크리트(20)의 내부에 시멘트몰탈을 주입하는 그라우팅 주입파이프(50)와 공극의 발생을 방지하기 위한 에어배출구(60)가 설치되어 있다.And as can be seen in Figure 3 showing a plan view of the subject innovation, the grouting injection pipe 50 for injecting cement mortar into the well body concrete 20 and the air outlet 60 for preventing the generation of voids are installed It is.
또한 본 고안의 전체적인 구조는 도 4에 도시된 바와 같이, 우물통 본체콘크리트(20)가 시공 설치되고, 상기 우물통 본체콘크리트(20)의 내부 암바닥(10)까지 그라우팅 파이프(50)와 에어배출구(60)가 설치장착되고, 그라우팅몰탈이 주입된 암바닥(10)의 상부에 수중저반 콘크리트(40)가 타설되어 형성되고, 상기 수중저반 콘크리트(40)의 상부에는 중간채움콘크리트(30)와 상단콘크리트(80)가 형성되는 구조로 되어 있다.In addition, the overall structure of the present invention, as shown in Figure 4, the well body concrete 20 is installed, the grout pipe 50 and air to the inner rock bottom 10 of the well body concrete 20 The outlet 60 is installed and installed, and the subfloor concrete 40 is poured on the upper portion of the rock bottom 10 into which the grouting mortar is injected, and the intermediate filling concrete 30 is formed on the upper portion of the subfloor concrete 40. And the upper concrete 80 is formed.
그리고 본 고안의 전체적인 시공순서를 살펴보면 우물통본체 콘크리트의 시공완료 및 내부굴착후 암반까지 침하시키고, 그라우팅 파이프와 에어배출구를 설치하고, 주입한후 우물통하단 수중저반 콘크리트를 타설하고 물푸기 및 중간채움 콘크리트를 타설하고 시멘몰탈 그라우팅 주입후 상단 콘크리트를 타설하는 것으로 완료된다.In addition, the overall construction sequence of the present invention is to settle down to the rock after the completion of construction and internal excavation of the well body concrete, install grouting pipes and air outlets, and inject the subfloor concrete at the bottom of the well after pouring and It is completed by pouring filled concrete, pouring cement mortar grouting and then pouring the top concrete.
