Description

에이치형 파일을 이용한 옹벽선반 부착 직립식 옹벽 및 그 시공방법{Straight retaining wall having a shelf using H-shaped piles and constructing method thereof} Straight retaining wall having a shelf using H-shaped piles and constructing method

본 발명은 성토 및 절토사면을 직립면으로 형성하기 위하여 H형 파일을 이용한 옹벽선반 부착 직립식 옹벽 및 그 시공방법에 관한 것으로서, 옹벽을 설치하고자 하는 절토 및 성토 사면에 H형 파일을 지반에 타입하고 H형 파일 주위에 옹벽 벽체 보강철근을 조립설치하며 옹벽하부 벽체에 콘크리트를 타설양생하고 옹벽선반 하부를 뒷채움을 한 후에 옹벽 벽체 후부인 성토 및 절토면쪽에 H형 파일에 직각으로 연결하여 옹벽선반을 이루는 옹벽 선반 보강철골을 설치하고 옹벽 선반 보강 철골의 상하부에 옹벽 선반 보강철근을 조립설치하고 옹벽선반 및 옹벽상부 벽체에 콘크리트를 타설양생하고 옹벽선반 상부에 뒷채움을 하는 것이다.        The present invention relates to an upstanding retaining wall with a retaining wall shelf using an H-shaped pile to form a fill and a cut slope as an upright surface, and a construction method thereof. Retaining wall wall reinforcement is installed around H-shaped pile and concrete is laid on the lower wall of the retaining wall to backfill the lower wall of the retaining wall, and the retaining wall is connected to the pile and cut surface at the rear of the retaining wall at right angle to form the retaining wall shelf. Retaining wall shelf reinforcing steel is installed, and retaining wall shelf reinforcing steel is assembled and installed on the upper and lower parts of the retaining wall shelf reinforcing steel, casting concrete on the retaining wall shelf and the upper wall of the retaining wall and filling the upper part of the retaining wall shelf.

본 발명은 성토 및 절토된 구간에서 옹벽설치가 필요한 구간에 설치하거나 또는 도로 및 철도사면 아래에 옹벽을 설치할 경우에 설치되는 것으로서 토압을 견디면서 별도의 가시설의 설치를 피하거나 또는 절토 또는 성토 구간의 사면이 높아 옹벽이 과대해지는 것을 방지하기 위하여 H형 파일을 절토 또는 성토 구간에 직립으로 설치하고 옹벽선반을 설치하여 토압이 옹벽선반에 작용하므로서 직립식 옹벽이 전도 또는 활동하게되는 것을 방지하는데 그 목적이 있다.       The present invention is installed when the retaining wall is installed in the section of the fill and cut section, or when the retaining wall is installed under the road and railway slopes, and withstands the earth pressure while avoiding the installation of a separate temporary facility or the cut or fill section. In order to prevent the retaining wall from being oversized due to the high slope, the H-shaped pile is installed upright in the cut or fill section and the retaining wall shelf is installed to prevent the upright retaining wall from conducting or acting as the earth pressure acts on the retaining wall shelf. There is this.

종래의 직립식 흙막이는 도 1a에서 보는 바와 같이 절토 또는 성토 사면에 H형 파일(14)을 지반(1)에 타입하여 일정길이의 근입부(3)를 형성하여 설치한 것으로서 토압에 의한 횡방향 변위가 커서 높이가 낮은 가시설에나 사용되며 사면의 높이가 클경우에는 흙막이(2)가 횡방향 토압에 의해 변위가 발생되어 흙막이(2)가 붕괴되는 문제점이 있으며, 도 1b와 같이 절토 또는 성토구간의 사면에 설치되는 중력식 옹벽(4)은 사면의 높이가 높을 경우에는 중력식 옹벽(4)의 크기가 과대해지는 문제점과 중력식 옹벽(4)의 전도 및 활동을 방지하기 위하여 옹벽기초(5)가 과대해져 비경제적이며 사면상부에 설치되는 도로 또는 시설물의 하부에 까지 터파기의 영향이 미치는 문제점이 상존하여 왔다.       Conventional upright mudstones are formed by installing the H-shaped piles 14 on the ground 1 on the cut or fill slopes as shown in FIG. 1A to form a root indentation 3 having a predetermined length. When the height of the slope is large and the slope is large, the displacement is caused by the transverse earth pressure, so that the soil barrier 2 collapses, and as shown in FIG. Gravity retaining wall (4) is installed on the slope of the slope of the retaining wall foundation (5) is excessive in order to prevent the problem that the size of the gravity retaining wall (4) is excessive and the fall and activity of the gravity retaining wall (4) when the slope height is high There has been a problem that the effect of the excavation even down the road or facility installed on the slope and uneconomical has existed.

본 발명의 목적은 옹벽을 벽체식으로 직립시키켜 종래의 옹벽에서와 같은 확대기초 터파기 및 가시설 없이도 이미 성토되어 사용중인 철도 및 도로사면 구간에 옹벽설치가 가능하며 또한 옹벽을 설치할 기초지반이 연약하여도 H형 파일을 지지층까지 타입 또는 천공후 관입하여 지지케하므로서 설치 가능토록하였으며, 절토구간에서는 터파기로 인한 급구배 형성과 사면 높이의 증가로 인한 시공중 안정성 저하요인이 없도록 하기 위하여 H형 파일을 지반에 타입 또는 천공후 관입시켜 지지케하고 횡방향 토압에 저항하기 위하여 옹벽벽체에 직각으로 옹벽선반을 형성하여 옹벽벽체에 작용하는 횡방향 토압을 경감시킬뿐만 아니라 옹벽선반에 의하여 횡방향의 토압이 옹벽선반에 의해 2등분으로 분할되어 옹벽벽체에 작용하게되므로 옹벽선반이 없어 횡방향의 토압의 전체가 바로 옹벽벽체에 작용할때보다 훨씬 줄어든 토압을 받게되어 옹벽이 안정성을 갖도록 하는 것이다.        It is an object of the present invention to install the retaining wall in the railway and road slope sections which are already laid and used without the enlarged foundation break and temporary equipment as in the conventional retaining wall. Even if the H-type piles are supported by the type or perforation after supporting them to the support layer, the H-type piles can be installed in the cut section so that there is no deterioration of stability during construction due to the rapid gradient formation and the increase of the slope height. In order to support the intrusion after type or drilling in the ground and to resist the lateral earth pressure, the retaining wall shelf is formed at right angles to the retaining wall to reduce the lateral earth pressure acting on the retaining wall, as well as the lateral earth pressure by the retaining wall shelf. There is no retaining wall shelf because it is divided into two parts by retaining wall shelf and acts on the retaining wall. The entire transverse earth pressure is subjected to much less earth pressure than when it is applied to the retaining wall, so that the retaining wall is stable.

도 2는 본 발명에 의한 H형 파일을 이용하여 설치한 직립식 옹벽에 옹벽선반이 설치된 것을 보여주는 도면으로서 H형 파일(14)을 지반의 지지층까지 타입 또는 천공후 관입하여 타입부(15)를 형성하고 타입부(15)는 지지층까지 타입되는 옹벽기초부(17)와 일정깊이의 옹벽근입부(16)로 구분하여 설치한다. 옹벽 근입부(16)의 깊이는 지반 표면에서부터 1m ~ 1.5m정도의 깊이까지 철근을 조립설치하고 콘크리트(19)를 타설양생하여 설치하는데 이는 장래의 세굴이나 인공적으로 절취되므로서 영향을 받지 않게 하기 위함이며 또한 우리나라 동절기의 동결의 영향을 주는 깊이를 나타내는 것으로서 옹벽(10)에 기후 및 외적 요인의 영향을 적게 주기 위함이며 이 부분이 옹벽(10)에 작용하는 횡방향의 토압에 따른 활동에 저항하는 활동 방지벽의 기능을 가지도록 이 부분을 보강하기 위한 목적도 있다. 또한, 옹벽벽체(11)는 H형 파일(14)을 절, 성토면에 직립시켜 타입 또는 천공후 관입하고 H형 파일(14)의 전후면에 옹벽벽체 보강철근(18)을 조립설치하고 옹벽하부 벽체(12)에 콘크리트(19)를 타설양생한 후 옹벽선반이 설치될 위치까지 뒷채움을 실시하고 배면에 옹벽선반(30)을 설치하기 위하여 H형 파일(14)에 직각으로 옹벽선반 보강철골(32)을 설치하고 옹벽선반 보강철골(32)의 상하부에 옹벽선반 보강철근(31)을 조립설치하고 콘크리트(19)를 타설양생하여 옹벽(10)을 설치하고 옹벽선반 상부(33)에 뒷채움을 실시한다. 이때 H형 파일(14)의 간격은 설치될 옹벽높이 및 배면 토질에 따른 발생토압과 상재하중, 지반 지지력, H형강의 종류별 단면계수, 벽체두께등을 고려하여 결정하며, 그 간격은 1.5 ~ 2.5m이나 바람직한 간격은 1.8m이다. 또한, 옹벽선반(30)의 설치길이는 옹벽벽체(11) 높이의 35 ~ 45%의 길이로 설치하는 것이 바람직하다. 옹벽선반(30)의 설치는 옹벽 벽체(11)에 작용하는 횡방향의 토압을 옹벽벽체(11)의 옹벽선반 상부(33)에 뒷채움되는 토사의 수직토압과 옹벽벽체(11)에 작용하는 횡방향의 토압이 상호 상쇄되어 옹벽벽체(11)에 실질적으로 작용되는 토압이 경감되도록하여 옹벽이 안전성을 갖도록하는데 있다.       2 is a view showing that the retaining wall shelf is installed on an upright retaining wall installed by using the H-shaped pile according to the present invention. The type portion 15 is formed by separating the retaining wall foundation portion 17, which is typed to the support layer, and the retaining wall root portion 16 having a predetermined depth. The depth of the retaining wall indentation 16 is installed by assembling and reinforcing the reinforcing bars from the ground surface to a depth of about 1m to 1.5m and placing concrete 19 to prevent them from being affected by future scour or artificial cutting. In order to reduce the influence of climate and external factors on the retaining wall (10), this part is resistant to the action of transverse earth pressure acting on the retaining wall (10). It is also intended to reinforce this part to have the function of an activity barrier. In addition, the retaining wall wall 11 penetrates the H-shaped pile 14 upright on the cut and fill surface, and penetrates it after type or perforation, and installs and installs the retaining wall reinforcing bar 18 on the front and rear surfaces of the H-shaped pile 14.
