도로측구 보수방법{METHOD FOR REPAIRING ROAD GUTTER}Road side repairing method {METHOD FOR REPAIRING ROAD GUTTER}

본 발명은 도로측구 보수방법에 관한 것으로, 더욱 상세하게는 강도가 높고 양생기간이 짧은 모르타르가 적용됨으로써 도로측구가 적은 깊이로 파쇄되어도 안정된 강도가 유지될 수 있고, 공기가 단축될 수 있는 도로측구 보수방법에 관한 것이다.The present invention relates to a roadside repairing method, and more specifically, by applying a mortar having high strength and a short curing period, even when the roadside is crushed to a small depth, stable strength can be maintained, and roadsides that can shorten air. It relates to a repair method.

일반적으로 도로는 아스팔트 혹은 콘크리트로 포장되며, 경계석이 도로에 설치되어 도로를 인도와 차도로 분리한다. 그리고, 차도의 가장자리에는 도로측구가 마련됨으로써 도로에 고인 물을 배수시킬 수 있다. Generally, roads are paved with asphalt or concrete, and boundary stones are installed on the roads to separate roads from sidewalks and driveways. In addition, the road side opening is provided at the edge of the roadway to drain the accumulated water on the road.

이러한 도로측구는 차량 등에 의한 충격, 진동, 그리고 시간의 경과에 따라 노후될 수 있음으로 보수공사가 요구된다.These roadside doors may be damaged due to impact, vibration, and the lapse of time due to a vehicle, and require repair work.

도 1에는 이러한 도로측구를 보수하는 과정이 도시된다. 도시된 바와 같이, 도로측구(1)는 일정 깊이(D), 바람직하게는 200mm 정도 파쇄된다. 도로측구(1)를 파쇄한 후, 파쇄된 부위에 통상적인 성분의 레미콘(3)이 포설될 수 있다. 그리고, 이 레미콘(3)이 일정 기간 양생됨으로써 도로측구(1)의 보수공사가 완료될 수 있다.1 shows a process for repairing such a road side. As shown, the roadside opening 1 is crushed to a certain depth D, preferably about 200 mm. After the road side opening 1 is crushed, the ready-mixed concrete 3 of the conventional component may be installed at the crushed site. In addition, since the ready-mixed concrete 3 is cured for a predetermined period, the repair work of the road side opening 1 may be completed.

그러나, 이러한 도로측구의 보수방법은, 경계석 인접구역이 파쇄기 등의 장비에 의하여 약 200mm 정도의 깊이로 파쇄되므로, 장비 구동시 발생하는 진동으로 인하여 경계석이 흔들림으로써 경계석의 위치 혹은 자세가 변동되어 미관을 해칠 수 있는 문제점을 가지고 있다.However, in the repair method of the road side, the area adjacent to the boundary stone is crushed to a depth of about 200mm by the equipment such as a crusher, the position or attitude of the boundary stone is changed due to the shaking of the boundary stone due to the vibration generated when driving the equipment. There is a problem that can harm.

그리고, 파쇄기에 의하여 경계석 인접 구역이 비교적 깊게 파쇄되므로, 파쇄시간이 길어짐으로써 소음이 발생될 수 있는 문제점이 있다. In addition, since the adjacent areas of the boundary stone are crushed relatively deeply by the crusher, there is a problem that noise may be generated by the crushing time being long.

또한, 통상적인 성분의 레미콘은 양생기간이 약 28일 정도 소요되므로, 이러한 레미콘이 도로측구의 파쇄부에 타설되는 경우, 공사기간이 연장될 수 있고, 이로 인하여 교통불편이 초래되는 문제점이 있다.In addition, since the ready-mixed concrete of the conventional component takes about 28 days, when the ready-mixed concrete is placed in the crushing part of the road side, the construction period may be extended, resulting in a traffic inconvenience.

따라서, 본 발명의 목적은 상기한 바와 같은 종래의 문제점을 해결하기 위한 것으로, 강도가 높고 양생기간이 짧은 모르타르가 적용됨으로써 도로측구가 얇은 깊이로 파쇄되어도 경계석의 흔들림이 방지될 수 있고, 보수공사가 단시간에 완료될 수 있는 도로측구 보수방법을 제공하는 것이다.Therefore, an object of the present invention is to solve the conventional problems as described above, by applying a mortar of high strength and short curing period can be prevented from shaking the boundary stone even when the road side crushed to a thin depth, repair work It is to provide a roadside repair method that can be completed in a short time.

상기한 바와 같은 목적을 달성하기 위하여, 본 발명의 바람직한 실시예는 도로측구가 일정 깊이로 파쇄되어 파쇄부가 형성되는 단계; 상기 도로측구가 파쇄된 후, 상기 파쇄부에 폴리머 3-5중량%와, 알루미늄 분말 4-6 중량%와, 시멘트 35-40중량%와, 규사 45-50중량%와, 실리카퓸 2-4중량%, 혼화재 1-3중량%의 비율로 이루어진 프리믹스 타입 모르타르를 포설하는 단계; 그리고 상기 프리믹스 타입 모르타르가 양생되는 단계를 포함하는 도로측구 보수방법을 제공한다.In order to achieve the above object, a preferred embodiment of the present invention comprises the steps of crushing the road side mouth to a certain depth to form a crushing unit; After the road side pulverization was crushed, 3-5 wt% polymer, 4-6 wt% aluminum powder, 35-40 wt% cement, 45-50 wt% silica sand, silica fume 2-4 Laying the premix type mortar in a ratio of 1% by weight to 1% by weight of admixture; And it provides a road side repair method comprising the step of curing the premix type mortar.

본 발명에 따른 도로측구 보수방법은 강도가 우수한 모르타르가 도로측구의 파쇄부에 포설됨으로써, 파쇄부의 깊이가 경계석의 하부보다 얕아도 충분한 강도가 유지될 수 있음으로, 시공시 발생할 수 있는 진동으로 인하여 경계석의 위치 혹은 자세가 변동되는 것이 방지될 수 있는 장점을 가지고 있다.In the roadside repair method according to the present invention, since the mortar having excellent strength is installed in the crushing portion of the roadside, sufficient strength can be maintained even if the depth of the crushing portion is shallower than the lower portion of the boundary stone, due to the vibration that may occur during construction. The position or posture of the boundary stone can be prevented from changing.

그리고, 본 발명에 따른 도로측구 보수방법은 경계석 인접 구역이 비교적 얇게 파쇄되므로, 파쇄시간이 단축될 수 있고, 소음이 감소될 수 있는 장점을 가지고 있다.In addition, the roadside repair method according to the present invention has a merit that the adjacent area of the boundary stone is relatively thinly crushed, so that the crushing time can be shortened and the noise can be reduced.

또한, 본 발명에 따른 도로측구 보수방법은 양생이 빠른 모르타르가 도로측구의 파쇄부에 포설됨으로써, 공사기간이 단축될 수 있고, 교통에 끼치는 영향이 적은 장점을 가지고 있다.In addition, the road-side repair method according to the present invention has a merit that the fast curing mortar is installed in the crushing portion of the road side, the construction period can be shortened, it has the advantage of less impact on traffic.

이하, 첨부된 도면을 참조하여 본 발명의 실시예에 따른 도로측구 및 그 보수방법이 상세하게 설명된다.Hereinafter, with reference to the accompanying drawings will be described in detail the road side mouth and its repair method according to an embodiment of the present invention.

도 2는 본 발명에 따른 도로측구 보수방법에 의하여 도로측구가 보수되는 과정이 도시된 도면이고, 도 3은 본 발명에 따른 도로측구 보수방법이 도시되는 순서도이다.2 is a view illustrating a process of repairing a road side outlet by the road side repairing method according to the present invention, and FIG. 3 is a flowchart illustrating a road side repairing method according to the present invention.

도시된 바와 같이, 본 발명이 제안하는 도로측구 보수방법은 도로측구(10)를 일정 깊이(D)로 파쇄하는 단계(S100)와, 도로측구(10)가 파쇄된 후, 파쇄된 부위에 프리믹스 타입 모르타르(12)를 포설하는 단계(S110)와, 그리고, 프리믹스 타입 모르타르(12)를 양생하는 단계(S120)를 포함한다.As shown, the road-side repair method proposed by the present invention step (S100) of shredding the road side opening 10 to a predetermined depth (D), and after the road side opening 10 is crushed, premixed to the crushed site And arranging the type mortar 12 (S110), and curing the premix type mortar 12 (S120).

상기 파쇄단계(S100)에서는 도로측구(10)가 파쇄기에 의하여 일정 깊이, 바람직하게는 약 50mm 정도의 얇은 깊이(D)로 파쇄됨으로써 파쇄부(14)가 형성된다. 이때, 사용되는 파쇄기는 해머식 타정기, 다이아몬드 치핑기 등 다양한 종류의 파쇄기가 적용될 수 있다.In the shredding step (S100), the road side mouth 10 is shredded by a shredder to a predetermined depth, preferably, a thin depth D of about 50 mm, thereby forming the shredded portion 14. At this time, the crusher to be used may be applied to various kinds of crushers, such as hammer type tabletting machine, diamond chipping machine.

그리고, 파쇄부(14)의 깊이(D)가 약 50mm 정도이므로, 파쇄된 부위의 바닥면(16)이 경계석(18)의 저면(20)보다 상부에 위치하게 된다. 즉, 파쇄부(14)가 시공되는 경우, 경계석(18)의 하부가 굴삭되지 않는다.In addition, since the depth D of the crushed portion 14 is about 50 mm, the bottom surface 16 of the crushed portion is positioned above the bottom surface 20 of the boundary stone 18. That is, when the crushing part 14 is constructed, the lower part of the boundary stone 18 is not excavated.

따라서, 파쇄과정에서 발생될 수 있는 파쇄기의 진동 등으로 인하여, 경계석(18)의 위치 혹은 자세가 변동되는 것이 방지될 수 있다.Therefore, due to the vibration of the crusher, etc., which may occur during the crushing process, the position or posture of the boundary stone 18 can be prevented from being changed.

또한, 도로측구(10)가 비교적 얇은 깊이(D)로 파쇄되므로 파쇄시간도 단축될 수 있고, 소음도 감소될 수 있다.In addition, since the road side opening 10 is crushed to a relatively thin depth (D), the crushing time can be shortened, and the noise can be reduced.

한편, 상기에서는 도로측구(10)의 바닥면(16)이 수평으로 파쇄되는 것으로 설명하였지만, 바닥면(16)이 다른 형상으로 파쇄되는 것도 가능하다.Meanwhile, in the above description, the bottom surface 16 of the road side opening 10 is crushed horizontally, but the bottom surface 16 may be crushed into another shape.

즉, 도 4에 도시된 바와 같이, 파쇄부(30)의 바닥면(32)은 단턱(34)이 형성되어 서로 단차지도록 시공될 수 있다. 이와 같이, 파쇄부(30)의 바닥면(32)이 단차진 형상으로 시공됨으로써 파쇄부(30)에 모르타르(36)가 포설되는 경우, 기존 콘크리트층(38)과 모르타르층의 결합력이 증가될 수 있다.That is, as shown in FIG. 4, the bottom surface 32 of the crushed portion 30 may be constructed such that the step 34 is formed to step between each other. As such, when the bottom surface 32 of the crushed portion 30 is installed in a stepped shape, when the mortar 36 is installed in the crushed portion 30, the bonding force between the existing concrete layer 38 and the mortar layer may be increased. Can be.

그리고, 파쇄부(30)의 바닥면(32)이 단차진 형상을 갖는 경우, 규격이 다양한 파쇄기가 적용될 수 있는 이점이 있다. In addition, when the bottom surface 32 of the crushing unit 30 has a stepped shape, there is an advantage that various crushers can be applied.

즉, 파쇄부(30)의 시공에 사용되는 파쇄기에 있어서, 파쇄롤러와 같이 노면을 파쇄하는 부분의 폭이 파쇄부(30)의 폭보다 작은 경우, 파쇄부(30)의 폭에 맞는 파쇄기를 선택할 필요없이, 작은 폭을 갖는 파쇄기가 시공에 사용될 수 있다.That is, in the crusher used for the construction of the crushing portion 30, when the width of the portion crushing the road surface, such as the crushing roller is smaller than the width of the crushing portion 30, the crusher suitable for the width of the crushing portion 30 Without the need to select, a crusher with a small width can be used for construction.

다시, 도 2 및 도 3을 참조하면, 상기된 바와 같이, 도로측구(10)의 파쇄부(14)가 형성된 후, 프리믹스 타입 모르타르(Pre-mixed type mortar;12)가 파쇄부(14)에 포설되는 단계(S110)가 진행된다.Referring again to FIGS. 2 and 3, as described above, after the crushed portion 14 of the road side opening 10 is formed, a pre-mixed type mortar 12 is applied to the crushed portion 14.

즉, 부착강도와 압축강도의 경우, 본 발명에 따른 모르타르가 비교예에 비하여 우수한 강도를 나타냄을 알 수 있다. 특히, 압축강도의 경우, 본 발명의 모르타르의 경우, 12시간 경과 후 12.7 MPa의 강도가 측정된 반면, 비교예는 측정이 불가하다. That is, in the case of the adhesion strength and the compressive strength, it can be seen that the mortar according to the present invention shows an excellent strength compared to the comparative example. Particularly, in the case of the compressive strength, in the case of the mortar of the present invention, the intensity of 12.7 MPa was measured after 12 hours, whereas the comparative example cannot be measured.

또한, 휨강도를 비교한 경우에도 28일 경과시점에서, 실험예와 비교예가 상당한 차이를 보인다. In addition, even when the bending strength was compared, 28 days later, the experimental example and the comparative example show a significant difference.

이와 같은 성분들로 이루어진 모르타르를 시공부에 포설하여 양생시킴으로써 보수작업이 이루어질 수 있다.Repair work can be made by laying and curing the mortar made of such components in the construction.
