Description
본 고안은 터널의 보강 방수공법에 관한것으로 상세하게는 특히, 공간 몰타르 라이닝공법에 의하는 터널의 치수 보강에 관한것이다.The present invention relates to the reinforcement waterproofing method of the tunnel, and more particularly, to the dimensional reinforcement of the tunnel by the spatial mortar lining method.
재래식 터널은 대부분 암벽에 무근 콘크리트로 라이닝하며 일반적으로 누수가 심한 기존도로 터널 내부에 특수 방수 공법까지 동원하여 방수공사를 시행하였으나 실패하는 경우가 많았다. 또한 방수 및 라이닝 보강 목적으로 대부분 긴터널에서는 값이 비싼 이동식 철재 거푸집을 이용하여 두께(t) 20 cm 이상의 콘크리트 이중벽 설치를 시행하는것이 일반적인 공법으로 사용되고 있으나 이공법은 시공시 교통이 완전히 통제되는 불편이 따르고 특히 산악 터널과 같은 우회도로가 없는 위치에서는 적용할수가 없으며 시공이 복잡하고 공기 및 공비가 많이 소용되고 시공후엔 터널의 단면 부족 현상이 발생하는가 하면 차량 통행으로 인한 진동, 터널 배면의 압력수등으로 인하여 누수가 재발하는 사례가 많았다.Conventional tunnels are mostly lined with plain concrete on rock walls, and in general, watertight construction was carried out using special waterproofing methods inside the tunnels with heavy leakage. In addition, for the purpose of waterproofing and lining reinforcement, in most long tunnels, the installation of concrete double walls with a thickness (t) of 20 cm or more using expensive mobile formwork is used as a general construction method. In particular, it is not applicable to locations without bypass roads such as mountain tunnels, and the construction is complicated, air and aerobics are used, and the tunnel section lacks after construction. There were many cases of recurrence of leakage due to back pain.
본 고안은 이러한 결점을 시정하는 공법으로 록크 볼트를 이용한 이중벽 설치 공법으로서 시공시 가도나 우회도로가 필요없이 차량소통에 큰지장을 주지않으며 거푸집이 필요하지 않고 용이하게 시공할수 있는 터널 보강 치수 공법을 제공하려는 것이다.The present invention is a method for correcting these shortcomings. It is a double wall installation method using lock bolts, which does not require highways or bypass roads, does not interfere with vehicle communication, and does not require formwork. Is to provide.

본 고안은 기존 터널 벽면에 드레인을 긴 록크 볼트를 박아 붙이고 철망을 록크 볼트에 걸어 붙인 다음 시멘트 몰타르로 5-6회 미장하고 또 철망을 걸어 붙인 다음 5-6회 시멘트 몰탈로 미장하여 마감하는 터널 라이닝 치수 보강공법이다.The design of the present invention is to insert a long lock bolt to drain the existing tunnel wall and fasten the wire mesh to the lock bolt, and then plaster it 5-6 times with cement mortar, and then attach the wire mesh and finish with 5-6 times cement mortar. Lining dimension reinforcement method.
본 고안을 양호한 실시예 및 첨부 도면을 참조하여 더욱 자세히 설명한다.The invention is described in more detail with reference to the preferred embodiments and the accompanying drawings.
도 1 , 도 2 , 도 3 에서 터널내부를 깨끗이 청소하고 누수가 심한곳은 배수파이프를 설치하여 측구로 배수한다.In Figures 1, 2, and 3, the inside of the tunnel is cleaned and drained to the side by installing a drain pipe where the leak is severe.
너털 내부 벽체(10)에 천공하여 지름 20mm 길이 200mm의 록크볼트(11)를 설치한다. 배수를 원활히 하기 위하여 부직표(12)를 벽면(10)에 부착하여 앵커볼트(11')로 고정시킨다. 다음 코어드레인(13)을 부착 시키는데 이때 앵커볼트(11'), 록크볼트(11) 구멍 및 코어드레인(13) 이면부위에 에폭시 퍼티 실링제(17)(도 3 참조)등을 충전하여 누수가 되지 않도록 시공한다.The lock bolt 11 having a diameter of 20 mm and a length of 200 mm is installed by drilling into the inner wall of the nut. In order to facilitate drainage, the nonwoven table 12 is fixed to the anchor bolt 11 'by attaching it to the wall surface 10. Next, the core drain 13 is attached. At this time, the anchor bolt 11 ', the lock bolt 11 hole, and the backside of the core drain 13 are filled with an epoxy putty sealing agent 17 (see FIG. 3) and the like. Do not install.
코어드레인(13)을 부착시에 앵커볼트(11')를 사용하여 부착하고 겹이음을 충분히 하여 누수가 되지않도록한다. 이때 상부 측면에서 누수되는 물은 부직포(12)와 코어드레인(13)을 따라 유도되게 되므로 이를 측구 배수로(20)로 유도한다.When the core drain 13 is attached, it is attached using an anchor bolt 11 'and the overlapping is sufficient to prevent leakage. At this time, the water leaking from the upper side is guided along the nonwoven fabric 12 and the core drain 13, so it is guided to the side opening 20.
다음, 1차 철망(14)을 몰타르가 잘 부착 될수 있는 규격품(메탈라스 243)을 사용하여 록크볼트(11)에 용접 접합한다. 1 : 1 비율 초조강 시멘트모르터(15)를 바르는데 양생시 진동으로 인한 처짐을 방지하여야 한다.Next, the primary wire mesh 14 is welded to the lock bolt 11 using a standard product (Metalas 243) that can be attached to the mortar well. 1: 1 ratio roughened cement mortar (15) is applied to prevent sagging due to vibration during curing.
2차 철망(14')을 부착하고 다시 모르터(15')를 발라 타설하고 모르터 양생시 건조 수축을 방지하기 위하여 습윤양생을 한다.Attach the secondary wire mesh 14 'and apply mortar 15' again to wet and cure the mortar to prevent dry shrinkage during curing.
이때 터널크기와 형상에 따라 라이닝 두께와 철망 강선의 굵기가 구조해석으로 결정되어야 하며 모르터는 수축이 크므로 수축이 작게 일어나는 무수축시멘트를 사용하며, 신축이음은 10 m 이내 간격으로 촘촘히 두어야 하며 모르터 바르기는 표면 건조가 되지 않도록 덧바르기를 하여야 한다.Depending on the tunnel size and shape, the thickness of the lining and the thickness of the wire mesh should be determined by the structural analysis. The mortar has a large shrinkage, so it uses a non-cemented cement that causes a small shrinkage, and the expansion joint should be closely spaced within 10 m. Applying should be done to prevent surface drying.
본 고안에 의한 터널 보강 보수치수공법은 종전공법에서 필요하였든 이동식 거푸집 및 콘크리트 펌프가 필요없으며 공사기간을 단축하고 공사중 차량 통행이 가능하며 타설작업상 필요한 최소 콘크리트 라이닝 두께보다 얇은 두께로도 가능하므로 터널을 통한 차도 공간의 손실이 작고 공사비도 적게 든다.Tunnel reinforcement repair dimension method according to the present invention does not require mobile formwork and concrete pump, which is needed in the previous method, shorten the construction period, allow the vehicle to pass during construction, and can be thinner than the minimum concrete lining thickness required for pouring work. Driveway loss of space is small and construction cost is low.
기존 터널의 라이닝 콘크리트가 역학적으로 부족하지않다면 본 고안의 공법은 터널 누수 대책공법으로 방수가 확실하고 일부 차량통행이 가능하며 공사비가 적게 드는 유용하고 경제적인 방식이다.If the lining concrete of the existing tunnel is not mechanically insufficient, the method of the present design is a tunnel leak prevention method, which is a useful and economical method of ensuring waterproofness, allowing some vehicles to pass, and low construction cost.
