Abstract
Description
본 발명은 포장도로를 지지하는 지반이 유실되거나, 다짐불량으로 인하여 침하되면서 발생되는 공간에 의해서 내려앉은 포장도로를 복구하는 침하되는 포장도로의 보수공법에 관한 것이다.The present invention relates to a repairing method for a settled pavement to recover a pavement settled by a space generated while the ground supporting the pavement is lost or settled due to poor compaction.
포장도로를 시공할 때는 도로가 신설되는 지반을 고르게 다짐하고, 아스팔트나 콘크리트로 다짐된 지반의 상부에 일정한 두께로 도포 하여 차량이 소통될 수있는 포장도로로 형성하였다.When constructing the pavement road, the ground on which the road is newly established is evenly compacted, and it is formed as a pavement road where vehicles can be communicated by applying a certain thickness to the upper part of the ground compacted with asphalt or concrete.
그러나, 이러한 도로는 중량이 무거운 차량이 많이 소통되기 때문에 지반의 다짐이 견고하게 실시되지 않으면, 차량의 중량에 의하여 지반이 침하되어 포장도로에 굴곡이 발생하여 차량의 고속 주행시 안전사고의 위험이 있어으며, 우천시 빗물이 포장도로를 지지하고 있는 지반에 침투하여 상기 지반이 빗물에 의해서 침하되는 문제점이 발생하였다.However, these roads are heavy traffic, so if the ground compaction is not firmly carried out, the ground is submerged by the weight of the vehicle and the road is bent on the pavement road, there is a risk of safety accidents during high-speed driving of the vehicle In rainy weather, rainwater penetrates into the ground supporting the pavement, causing the ground to be submerged by rainwater.
상기와 같이 침하된 포장도로를 보수하는 방법은 전단면보수, 부분단면보수, 덧씌우기 등으로 포장도로를 보수하여 사용하고 있지만, 전단면보수의 경우 주로 초조강이나 초속경시멘트로 침하부의 포장도로를 전부 철거후 재타설하는 공법으로 철거시 하부지반이나 보조기층을 제대로 다짐하지 못하고 포장도로만 교체하는 경우로 준공후 다시 지반 침하가 빈번하게 일어나 시공비가 과다하게 투입되는 문제점이 발생하며,As for the repairing of the submerged pavement as described above, the pavement is repaired by shearing surface repair, partial cross-section repair, overlay, etc. This is a method of re-installing after re-installing all of them, and it is not possible to compact the lower ground or auxiliary base during demolition and replaces only the pavement.
부분단면보수는 포장도로 표면을 5CM이하로 파쇄기 등으로 제거후 폴리머 계통의 재료로 표면을 재타설하는 공법으로 이 또한 하부지반의 불량으로 재하자가 많이 발생하고,Partial section repair is a method of removing the surface of the pavement road with less than 5CM with a crusher, and then re-placing the surface with polymer material.
덧씌우기는 침하된 부위에 종단선형을 고려하여 포장도로의 침하된 부분에 포장도로의 원료를 포설하는 방법으로 기존 포장도로가 손상된 상태에서 특별한 보수 없이 포장도로의 원료로 덧씌우기 하기 때문에 덧씌우기 후 줄눈부위 또는 균열부위로 반사균열이 발생되는 문제점이 발생하였다.Overlaying is a method of laying raw material of pavement on the submerged part of the pavement by considering the vertical line on the submerged part, so that the existing pavement is overlaid with raw material of the pavement without any special repair in the damaged state of the pavement. There was a problem that the reflection crack is generated in the site or cracks.
상기와 같은 문제점을 해결하기 위하여 특허등록 제133613호와 같이 침하된 지반과 포장도로 사이에 그라우팅 공간을 확보하고자 제1 경사공을 천공하고, 도로의 수평을 맞추기 위해 다수개 천공되는 제2 경사공을 통해 그라우트재를 충진하여 다른 경사공으로 그라우트재가 배출되면 내부 공간이 채워진 것으로 생각하고 다른 경사공으로 이동하는 방법으로 포장도로의 침하된 부분을 보수하여 사용하고 있으나, 상기 발명은 그라우팅 공간 확보와 그라우트재의 충진을 위하여 천공하는 구멍을 경사지게 형성한다고 기재되어 있으나, 경사공을 천공하는 핸드드릴의 무게가 무겁고 흔들림이 심해 경사지게 천공할 수 없으며, 그라우트재를 주입시 줄눈보수 및 균열보수가 이루어지지 않으면 그라우트재를 주입해도 그라우트재가 줄눈부와 균열부로 새어나와 침하된 부분이 그라우트재의 주입 압력을 받지 못하여 복귀되지 않는 문제점이 발생하였다.In order to solve the above problems, as shown in Patent Registration No. 133613, the first inclined hole is drilled to secure the grouting space between the submerged ground and the pavement, and the second inclined hole is drilled a plurality of times to level the road. When the grout material is discharged to other inclined holes through the filling of the grout material, the internal space is considered to be filled, and the submerged portion of the pavement is repaired and used by moving to another inclined hole. Although it is described that the drilled hole for filling is formed to be inclined, the hand drill for drilling the inclined hole is heavy and shaken so that it cannot be drilled inclinedly. Grout material leaks into joints and cracks I and the submerged part did not receive the injection pressure of the grout material did not return a problem occurred.
또한, 도 1에서 도시된 바와 같이 포장도로의 하부에 침하되어 형성되는 공간이 한곳이 아니고 여러 곳일 경우 그라우트재를 주입하여 다른 경사공으로 그라우트재가 배출되면 다른 경사공으로 이동하지만, 포장도로의 하부에 형성되는 공간이 여러 곳일 경우에는 한쪽 공간에만 그라우트재가 충진되고 다른 곳에는 충진이 되지 않아 재시공해야만 하며, 경사공으로 주입되는 그라우트재는 지반이 침하되면서 형성되는 공간을 모두 채울 때까지 주입해야 하므로, 하루에 주입이 끝나지 않고 며칠씩 연장하여 주입하지만, 그라우트재를 주입한 다음날 작업할 때 시멘트 등으로 형성되는 그라우트재가 경사공의 입구를 막아 재충천을 하지 못하여 심한 경우 재시공해야 하는 문제점이 발생하였다.In addition, as shown in FIG. 1, if the space formed by being settled in the lower part of the pavement is not one place, but in several places, when the grout material is discharged to another inclined hole by injecting grout material, it moves to another inclined hole, but is formed in the lower part of the pavement road. If there are several spaces, grout material is filled in only one space and not in other places, so it must be reconstructed. In addition, grout material injected into the slope hole must be injected until it fills all the spaces formed as the ground subsides. This does not end but inject by extending a few days, but when the grout material is injected the next day when the grout material formed of cement, etc. blocked the entrance of the oblique hole was not able to refill the problem occurred when the severe re-installation.
본 발명은 상기와 같은 문제점을 해결하기 위하여 지반침하로 발생되는 여러 곳의 공간을 통합시켜 작업이 신속하게 이루어지는 침하되는 포장도로의 보수공법을 제공하는 것이다.The present invention is to provide a repair method for a settled pavement road to work quickly by integrating the space of the various places generated by ground subsidence in order to solve the above problems.
본 발명은 그라우트재를 주입한 다음날 작업시 그라우트재에 의해서 막힌 주입공을 다시 뚫어 그라우트재를 주입할 수 있는 침하되는 포장도로의 보수공법을 제공하는 것이다.The present invention is to provide a repairing method of the settled pavement road to inject the grout material through the injection hole blocked by the grout material in the next day after the grout material is injected.

지반(2)과 포장도로(1)의 침하된 상태의 조사가 완료되면, 침하된 상태에 따라 주입공(4)을 포장도로(1)가 관통되도록 공간(3)이 형성된 방향으로 다수개를 천공한다.(S2)When the investigation of the subsided state of the ground 2 and the pavement 1 is completed, a plurality of injection holes 4 are inserted in the direction in which the space 3 is formed so that the pavement 1 penetrates according to the subsided state. Perforate (S2)
다수개의 주입공(4)이 포장도로(1)를 관통하여 공간(3)이 형성된 방향으로 천공되면, 주입공(4)으로 강한 수압의 물을 주입하여 다수개로 구획되면서 형성된 공간(3)이 수압에 의해서 구획되어 막힌곳이 뚫려 통합되면서 지반(2)에 형성된 공간(3)의 길(연결상태)과, 주입되는 물이 공간(3)에 차면서 물이 포장도로(1)의 줄눈이나 균열부로 물이 새는 것을 파악한다.(S3)When the plurality of injection holes 4 penetrates the pavement 1 and is drilled in the direction in which the space 3 is formed, the space 3 formed while being divided into a plurality by injecting strong water pressure into the injection hole 4 is formed. The block (blocked state) of the space (3) formed in the ground (2) and the water is injected into the space (3) while the water is filled in the joints or cracks of the pavement (1). To catch water leaks from wealth (S3)
포장도로(1)의 하부에서 지반(2)에 다수개 형성되는 공간(3)이 수압에 의해서 통합되면서 균열부와 줄눈부가 물이 새어나오며 파악되면, 상기 균열부와 줄눈부를 밀폐시켜 공간(3)에서 포장도로(1)쪽으로 역류되는 것을 방지한다.(S4)When a plurality of spaces (3) formed in the ground (2) in the lower part of the pavement (1) is integrated by the hydraulic pressure and the cracks and joints are identified as leaking water, the cracks and joints are sealed to close the space (3). ) To prevent backflow toward the pavement (1). (S4)
