본 발명은 균등침하를 유도할 수 있는 블럭식 보강토옹벽에 관한 것으로서, 특히 지반침하나 지진 기타 유해한 외력에 대항하여 축조된 다수의 옹벽구조물을 견고하게 지지할 수 있으며, 또한 블럭의 후면부에 설치된 보강재와의 연결수단으로 블럭과 블럭의 결합력 증진과 함께 블럭과 보강재의 결합을 확실하게 하여 보강재의 이탈에 따른 블럭의 붕괴나 변형을 방지할 수 있는 것에 관한 것이다. The present invention relates to a block-type reinforced earth retaining wall that can induce equal settlement, and in particular, it can firmly support a plurality of retaining wall structures constructed against ground subsidence, earthquakes, or other harmful external forces, and is also provided with a reinforcement provided at the rear of the block. As a means of connecting to and to enhance the bonding force of the block and the block and the reinforcement of the block to ensure that the collapse and deformation of the block due to the separation of the reinforcement.

일반적으로, 옹벽은 토압력에 저항하여 토체의 붕괴를 방지하기 위한 벽체 구조물을 말하는 것으로, 산악지는 물론 토지 가격이 높은 지역 등에서 토지를 효율적으로 이용하기 위하여 많이 이용한다. In general, the retaining wall refers to a wall structure for preventing the collapse of soil by resisting soil pressure, and is widely used for efficient use of land in mountainous lands and high land prices.

즉, 흙을 쌓아 올리거나 산을 깎아 내거나 해안을 메울 때 등에 사용하는데, 토사의 붕괴를 막기 위하여 제방이나 도로 측벽 등에 석재나 콘크리트 등으로 된 블럭을 이용하여 옹벽을 축조하는 것이 일반적이었다. In other words, it is used to pile up soil, cut down mountains, or fill up the coast. To prevent the collapse of soil, it is common to build retaining walls using blocks made of stone or concrete, such as embankments and road side walls.

그리고, 아파트 단지조성과 사면의 안전성 확보를 위한 시공, 교량교대 날개벽 시공과 그밖에 수로공사 등에 널리 축조하고 있다. In addition, it is widely built for the construction of apartment complexes and the safety of slopes, the construction of bridge shift wing walls, and other waterway works.

그러나, 콘크리트 옹벽은 보강하고자 하는 토양의 표층에 접근되어 설치되기 때문에 내부로부터의 균열에 취약하고, 높이 제한, 기초 처리비용의 과다 등 문제점이 있고, 동절기 시공 및 시공기간 단축 등이 어려웠으며, 지진, 폭우, 폭파 등 돌발적인 사고시 뒤채움 토사의 붕괴에 의한 옹벽의 안정성이 취약하였다. However, since the concrete retaining wall is installed close to the surface of the soil to be reinforced, it is vulnerable to cracking from the inside, and there are problems such as height limitation and excessive treatment cost, and it is difficult to shorten the construction and construction period in winter. Stability of retaining walls due to collapse of backfill soil during sudden accidents such as heavy rains and blasts was weak.

한편, 철 구조물의 경우 토양으로부터의 전단저항에는 효과가 있으나 쉽게 부식되는 문제점들이 있었다.On the other hand, in the case of the steel structure is effective in shear resistance from the soil, but there were problems that are easily corroded.

이러한 문제점을 해결하는 대안으로, 우수한 경제성, 전면 벽체의 자유로운 형상, 시공기간 단축, 지진에 강한 구조를 가능하게 하는 토목섬유(Geosynthetics) 보강재(특히, 지오그리드(geogrid) 보강재)를 이용한 보강토 옹벽의 축조가 증가하였다. As an alternative to solve this problem, the construction of reinforced earth retaining wall using geosynthetics reinforcement (especially geogrid reinforcement), which enables excellent economic feasibility, free shape of the front wall, short construction period, and earthquake resistant structure Increased.

종래의 보강토옹벽에 보강토로 뒷채움 후 지오그리드의 유동을 도시한 도면인 도 5에 도시된 바와 같이, 보강토옹벽의 후방에 보강토로 뒷채움시 보강토의 하중 때문에 상기 보강토옹벽의 후방에 고정되어 체결되어 있는 지오그리드의 파손이 불가피한 문제점이 있었다. As shown in FIG. 5, which shows the flow of the geogrid after backfilling the reinforcement soil in the conventional reinforcement soil wall, the geogrid is fastened to the rear of the reinforcement soil wall due to the load of the reinforcement soil when backfilling the reinforcement soil in the rear of the reinforcement soil wall. There was an inevitable problem of breakage.

그리고 보강토 옹벽은 사질토의 뒤채움 흙에 인장력이 크고 마찰력이 좋은 보강재를 수평으로 삽입하여 흙의 횡방향 변위를 억제함으로써 토체의 안정을 기하도록 한 것으로, 보강재, 뒤채움용 사질토(보강토) 및 전면 보호재(블럭)로 구성된다. Reinforcement soil retaining wall inserts a reinforcement material with high tensile strength and good friction force horizontally into the backfilling soil of sandy soil to stabilize the soil by suppressing the lateral displacement of the soil. Reinforcement, backfilling sandy soil (reinforcement soil) and the front surface It consists of a protective material (block).

이러한 블럭식 보강토옹벽은 도로, 철도 및 단지 조성시 용지확보 등에서 유리하기 때문에 콘크리트 옹벽을 대체하여 그 사용이 확대되고 있으며, 토목섬유 보강재와 함께 다수의 블럭을 조립, 적재하여 옹벽을 축조하였다. Since the block type reinforced earth retaining wall is advantageous in securing the land in the construction of roads, railways and complexes, the use of the reinforced concrete retaining wall is being replaced by the concrete retaining wall, and a plurality of blocks are assembled and stacked together with the geotextile reinforcement to build the retaining wall.

종래의 보강토 옹벽에서는 블럭과 보강재의 연결시, 보강재를 블럭과 블럭 사이에 블럭의 요철에 의해 일치하도록 직접 삽입하는 방식과 커넥터, 클립 및 연결핀 등의 연결장치에 의해 보강재를 삽입하는 방식으로 대별하였다. In the conventional reinforcement retaining wall, when the block and the reinforcement are connected, the reinforcement is directly inserted between the block and the block to match the unevenness of the block, and the reinforcement is inserted by the connecting device such as a connector, a clip, and a connecting pin. It was.

첫 번째로, 요철 블럭이나 전방 또는 후방에 턱이 있는 상·하 블럭 사이에 직접 보강재를 삽입하는 방식에서는, 보강재와 블럭의 연결력이 부족하고 블럭의 요철이나 턱에 의해 밀착시켜 시공하므로 보강재가 심하게 뒤틀리게 되어 보강재에 크랙이 발생하거나 끊어지게 되는 결과를 가져올 수 있다. First, in the method of inserting the reinforcement directly between the uneven block or the upper and lower blocks with the jaw in the front or the rear, the reinforcement material is insufficient because the connection force between the reinforcement and the block is insufficient and the construction is made in close contact with the uneven or the jaw of the block. Severe warpage can result in cracks or breaks in the stiffeners.

두 번째로, 커넥터, 클립 및 연결핀에 의한 연결방식은, 블럭 사이에 직접 삽입하는 방식 보다 결합방법이 진보되었으나, 블럭에 핀 공을 형성하기가 수월치 않고 시공시 핀의 삽입에 어려움이 따르며 여전히 보강재의 이탈이 예상된다. Secondly, the connection method by connector, clip and connecting pin is more advanced than the direct insertion method between blocks, but it is not easy to form a pin ball in the block and it is difficult to insert the pin during construction. Departure of the reinforcement is expected.

이와 같이, 종래의 보강토옹벽은 블럭과 보강재의 결합이 견고하지 못하기 때문에 보강재의 손상이나 이탈이 일어날 수 있고, 블럭의 파손이나 붕괴의 위험이 있었으며, 옹벽의 경사각도 조정이 한정되어 있는 문제점이 있다.As described above, the conventional reinforced earth retaining wall has a problem that the block and the reinforcement are not firmly bonded, so that the reinforcement may be damaged or dislodged, there is a risk of breakage or collapse of the block, and the inclination angle of the retaining wall is limited. have.

상기 기술한 문제점을 해결하기 위하여, 지반침하나 지진 기타 유해한 외력에 대항하여 축조된 다수의 옹벽구조물을 견고하게 지지할 수 있으며, 또한 블럭의 후면부에 설치된 지오그리드와의 고정수단으로 블럭과 블럭의 결합력 증진과 함께 블럭과 보강재의 결합을 확실하게 하여 보강재의 이탈에 따른 블럭의 붕괴나 변형을 방지할 수 있는 보강토옹벽을 제공하고자하는 것이 목적이다.In order to solve the above problems, it is possible to firmly support a plurality of retaining wall structures constructed against ground subsidence, earthquake or other harmful external force, and also as a means of fixing with the geogrid installed on the rear side of the block, The purpose of the present invention is to provide a reinforcing soil retaining wall which can prevent the collapse or deformation of the block due to the separation of the reinforcement by ensuring the combination of the block and the reinforcement together with the enhancement.

상기 기술한 목적을 달성하기 위하여, 상하좌우로 축조되며 상부와 하부를 관통하며 전방에 형성되는 삽입홀과 후방에 형성되는 보강홀이 구비되는 블럭과 지오그리드 및 상기 블럭과 지오그리드를 연결해주는 연결부로 구성되는 종래의 블럭식 보강토옹벽에 있어서, ㄷ형상으로 형성되며 양측의 끝단이 꺽임부가 형성되는 고정대와; 일측은 상기 고정대의 일측에 상하로 이동가능하게 삽입 고정되고, 타측은 양끝단에 삽입부가 형성되어 지오그리드가 결착되는 연결대; 및 S형상으로 양끝단에 형성된 끼움부가 형성되게 되며 상기 끼움부에 고정대의 꺽임부가 삽입고정되게 되는 체결구를 포함하여서 구성되는 것을 특징으로 하는 블럭식 보강토옹벽을 제공한다.In order to achieve the above object, it is composed of a block and a geogrid and the connecting portion connecting the block and the geogrid is built up, down, left and right and penetrates the top and bottom, the insertion hole formed in the front and the reinforcement hole formed in the rear In the conventional block-type reinforced soil retaining wall, which is formed in a c-shape and the end of both ends is formed with a bent portion; One side is inserted and fixed to be movable up and down on one side of the fixing rod, the other side is connected to the insertion end is formed on both ends geogrid is bound; And a fitting portion formed at both ends in an S shape and including a fastener in which a bent portion of the fixing portion is inserted into the fitting portion.
