Description

내진설계된 보강토 옹벽블록 및 그 시공방법{Seismic Retaining Wall Block and Its Construction Method}[0001] Seismic Retaining Wall Block and Its Construction Method [

본 발명은 내진설계된 보강토 옹벽블록 및 그 시공방법에 관한 것으로 내진판이 매립된 내진 기초콘크리트의 상면에 설치된 내진고무판 위에 보강토 블록을 적층하여, 지진에 의한 진동을 내진 기초콘크리트에 흡수하여, 상부 보강토 블럭의 흔들림이나 이탈을 방지하므로 지진시 상부구조물의 안정성이 지속적으로 유지되도록 하는 것이다.The present invention relates to an earthquake-resistant reinforced earth retaining wall block and a construction method thereof, in which a reinforcing earth block is laminated on an earthquake-resistant rubber plate provided on the upper surface of an earthquake-proof concrete embedded with an earthquake-resistant plate, So that the stability of the upper structure is continuously maintained during an earthquake.

일반적으로 옹벽블록은 토압에 저항하는 가장 일반적인 구조물로써, 도로, 철도, 항만, 방조제, 교대, 재개발 아파트 등의 용지의 제한에 따른 토지의 최적 이용을 목적으로 사용하며, 주위에서 자주 볼 수 있는 옹벽 구조물로는 도로와 경계를 이루는 주택부지, 산기슭 등의 경사면에 설치되어 토압 및 우수 등의 자연조건에 의해 이들의 붕괴를 막는 기능을 한다. Generally, the retaining wall block is the most common structure to resist the earth pressure. It is used for the optimum use of land according to the restriction of the paper such as road, railway, harbor, seawall, alternation, redevelopment apartment, The structure is installed on the slopes of the residential areas and the foothills which form the boundary with the road, and functions to prevent them from collapsing due to natural conditions such as earth pressure and storm.

근래의 옹벽구조물의 경우 설치 높이 만큼 거푸집을 설치한 다음 내측에 철근을 배근하고, 콘크리트를 타설하는시공법이 있었으나, 최근에는 콘크리트로 미리 단위 크기로 제조한 옹벽블록을 이용한 조립식 옹벽 공법이 다양하게 개발되고 있다.In recent years, there has been a construction method in which concrete is laid on the inner side of reinforced concrete building after installing a formwork as much as the installation height in recent years. Recently, however, various methods have been developed for the prefabricated reinforced concrete retaining wall .

블록을 기초 콘크리트의 위에 적층하면서 블록의 후방으로 그리드와 같은 보강재를 배치하고 토사를 적층하여 층별로 다짐하여 성토부를 시공하게 되는 보강토 옹벽에 있어서, 보강토 옹벽을 이루는 블록 즉, 보강토 옹벽블록의 전면은 콘크리트로 이루어지기 때문에 미관이 떨어지는 단점이 있었다. In the reinforced earth retaining wall, in which the blocks are stacked on the foundation concrete, a reinforcing material such as a grid is disposed at the rear of the block, and the soil is stacked and compaction is carried out to form the fillet. In the reinforcing earth retaining wall, And since it is made of concrete, there is a disadvantage that the appearance is reduced.

이를 개선하기 위하여 자연석으로 이루어진 자연석판을 보강토 옹벽블록의 전면에 설치하려는 시도가 이루어지고 있는데, 대한민국 공개특허공보 제10-2011-0002580호에 개시된 것처럼 종래 기술에서는 자연석판을 접착제를 이용하여 보강토 옹벽블록의 전면에 단순히 부착하는 방식을 이용하였다. In order to solve this problem, an attempt has been made to install natural slabs made of natural stones on the whole of the reinforced earth retaining wall block. As disclosed in Korean Patent Laid-Open Publication No. 10-2011-0002580, And simply attached to the front of the block.

상기 자연석판을 부착한 옹벽블록은 미관상 좋으나, 지진 발생시 진동에 의해 기초 콘크리트가 흔들려 옹벽블록이 뒤틀리거나 심하게 변형되는 단점이 있었다.The retaining wall block having the natural stone slab is good in appearance, but the base concrete block is shaken by vibration when an earthquake occurs, and the retaining wall block is warped or severely deformed.

또한, 종래 기초 콘크리트에는 내진 설계가 되어 있지 않아 약한 진동이나 지반 변위에 옹벽블록이 쉽게 변형되어 붕괴 위험을 초래하는 문제가 있었다.In addition, since the base concrete is not designed to have a seismic design, there is a problem that the retaining wall block is easily deformed due to weak vibration or ground displacement, resulting in collapse risk.

또한, 옹벽블록 후면에 채움되는 흙의 토압에 의해 조적된 옹벽블록이 수직하게 조적되지 못하고 일부 옹벽블록은 전방으로 돌출되는 배부름 현상이 발생하는 문제가 있었다.In addition, there is a problem that the retained wall blocks that are assembled due to the earth pressure filled in the back surface of the retaining wall block are not vertically aligned, and some of the retaining wall blocks protrude forward.

대한민국 공개특허공보 제10-2011-0002580호인 '자연석재를 전면에 부착한 옹벽블록'Korean Patent Laid-Open Publication No. 10-2011-0002580 'Retaining wall block with natural stone on the front'

상기 보강토 블록(40)은 상면 양측에 핀구멍(41)을 형성하고, 핀구멍(41)에 고정핀(51)이 구비된 연결핀(50)을 삽입하여 보강토 블록(40)을 일체화한다.The reinforcing soil block 40 has pin holes 41 formed on both sides of the upper surface thereof and a connecting pin 50 having a fixing pin 51 is inserted into the pin hole 41 to integrate the reinforcing soil block 40.

상기 보강토 블록(40)의 하면 전체면에 내진고무판(30')을 설치한다. An earthquake resistant rubber plate 30 'is provided on the entire lower surface of the reinforcing soil block 40.

상기 내진 기초콘크리트(20)에 설치된 내진고무판(30) 위에 보강토 블록(40)다수 개를 밀착되게 설치한다.A plurality of reinforcing soil blocks (40) are installed in close contact with each other on an earthquake-resistant rubber plate (30) provided on the earthquake-resistant foundation concrete (20).

이때, 약한 지반이나 지진 발생이 가능한 지반의 경우에는 내진고무판(30')이 일체화된 보강토 블록(40)을 설치한다.At this time, in the case of a weak ground or a ground capable of generating an earthquake, a reinforcing soil block 40 integrated with the earthquake-resistant rubber plate 30 'is installed.

상기 보강토 블록(40)은 연결핀(50)을 체결하여 고정하고, 그 위에 새로운 보강토 블록(40)을 반복적으로 설치하여 최상단까지 여러 층으로 축조하여 옹벽을 완성한다.The reinforcing soil block 40 is fixed by fastening the connecting pin 50, and a new reinforcing soil block 40 is repeatedly installed thereon.

그리고 첨부된 도 10와 같이 상단 보강토 블록(40')에 내진고무판(30'')을 설치하고 상부구조물(70)을 시공하므로, 지진 발생시 진동이 상부구조물(70)에 전달되는 것을 차단하여, 흔드림이나 붕괴 위험이 적어 안전성이 지속적으로 유지되도록 한다.10, since the vibration proof rubber block 30 '' is installed on the upper reinforcement block 40 'and the upper structure 70 is installed, the vibration is prevented from being transmitted to the upper structure 70 when an earthquake occurs, Ensure safety is maintained by minimizing the risk of lightning or collapse.
