Abstract

PURPOSE: A water tight bolt for tunnel segment assembling is provided to prevent water leakage in a bolt and reduce tunnel construction costs by simplifying the tunnel construction. CONSTITUTION: A shield tunnel method constructs lining of a tunnel by assembling a segment(5) manufactured in a factory together with digging. A water tight bolt is developed in order to improve a slant bolt method leaking water through a bolt hole. A head part(4) of a bolt is changed in such a manner that the head part(4) has a washer type structure. A rubber packing(2) is inserted into the head part(4) by enlarging a size of the head part(4). The bolt is tightened, so that a bolt hole is sealed.

Description

터널 세그멘트 조립을 위한 수밀 형 볼트{Water Tight Bolt For Tunnel Segment Assembling}Water Tight Bolt For Tunnel Segment Assembling}

실드 터널 공법은 굴착과 동시에 공장에서 제작한 세그멘트(5)를 조립하여 터널의 라이닝을 시공하는 공법으로 세그멘트의 조립에 경사 볼트(1)를 사용하는 공법이 근래에 개발되었으나 경사 볼트 공법은 볼트 구멍으로 쉽게 누수가 되는 결함이 있어 이를 개선 하기위해 수밀 구조의 볼트를 개발하여 경사볼트 식 세그멘트 터널의 누수를 방지함에 그 목적이 있다.The shield tunnel method is a method of constructing a tunnel lining by assembling a segment (5) manufactured at the same time as excavation, and a method of using an inclined bolt (1) for assembling a segment has recently been developed. The purpose of this is to prevent leakage of slope bolt-type segment tunnel by developing bolts of watertight structure to improve this problem.

토목 기술 분야로서 터널 세그멘트의 연결 방법에는 볼트 박스 방법과 경사 볼트 방법 등이 있으며 경사 볼트 방법은 구조가 간단한 이점은 있으나 볼트 구멍으로 쉽게 누수가 되는 것이 큰 문제점이다.In the field of civil engineering, the tunnel segment connection method includes a bolt box method and an inclined bolt method. The inclined bolt method has a simple structure, but it is a big problem to easily leak into a bolt hole.

경사 볼트 식 세그멘트 터널의 결함인 볼트 부분의 누수를 방지 하기위해 수밀 구조의 볼트를 개발하여 터널 방수 공사비와 유지 보수비를 절감하고자 함.In order to prevent the leakage of the bolt part which is a defect of the inclined bolt-type segment tunnel, the watertight bolt was developed to reduce the tunnel waterproofing and maintenance cost.

볼트의 머리부분(4)을 와샤를 삽입한 모양으로 넓게 변형시켜 고무 팩킹(2)을 삽입하고 볼트를 조이면 볼트 구멍이 밀폐되어 누수를 방지할 수 있는 구조로 되어있다.The head part 4 of the bolt is widely deformed into the shape in which the washer is inserted to insert the rubber packing 2 and tighten the bolt to seal the bolt hole to prevent leakage.

경사 볼트 식 세그멘트 터널의 문제점인 볼트 부위의 누수를 방지할 수 있고 시공도 간단하여 터널 공사비를 절감하고 공사기간을 단축할 수 있다.It is possible to prevent the leakage of the bolt part, which is the problem of the inclined bolt-type segment tunnel, and the construction is simple, which can save the tunnel construction cost and shorten the construction period.
