노면의 변형 및 균열방지구조{Structure for preventing deformation and crack in roadway}Structure for preventing deformation and crack in roadway

본 발명은 콘크리트 또는 아스팔트 포장도로의 노면에서 발생될 수 있는 변형현상과 균열현상 및 파손현상을 미연에 방지하거나 균열이 발생한 노면의 상부층 일부를 제거하여 차량의 주행방향을 가로지르는 방향으로 소정의 간격으로 오목한 부분을 형성시켜, 그 내부공간에 충진재로 충진하여 밀봉시키는 균열방지구조에 관한 것이다.The present invention prevents deformation and cracking and breakage that may occur on a road surface of a concrete or asphalt pavement, or removes a portion of an upper layer of a road surface in which cracking occurs, and thus, a predetermined interval in a direction crossing the driving direction of the vehicle. The present invention relates to a crack preventing structure that forms a concave portion and fills and seals the inner space with a filler.

종래에는 콘크리트 도로포장층의 파손 혹은 균열을 방지하기 위해서, 균열단부에 고무소재로 되어 있는 원통형상의 쐐기를 삽입한다. 원통형상의 중앙에 형성되어 있는 관통공에 쐐기봉을 삽입하는 공법이 이미 알려져 있다. 특히, 전술된 공법은 균열부의 확산을 방지하기 위해서 균열부의 끝에 쐐기를 삽입하는데, 원통형상의 쐐기에 맞는 적당한 크기의 쐐기매입공을 형성해야 하는 불편함이 있다. 고무소재로 되어 있는 원통형 쐐기는 시간적 추이와, 악천후 등과 같은 기후적 요인으로 쉽게 마모되는 경향이 종종 발생한다.Conventionally, in order to prevent breakage or cracking of the concrete pavement layer, a cylindrical wedge made of rubber material is inserted at the crack end. A method of inserting a wedge rod into a through hole formed in the center of a cylindrical shape is already known. In particular, the above-described method inserts a wedge at the end of the crack in order to prevent diffusion of the crack, which is inconvenient to form a wedge hole having a suitable size to fit the cylindrical wedge. Cylindrical wedges made of rubber are often prone to wear due to climatic factors such as temporal changes and bad weather.

이와 같이 특정물품을 도로포장층에 삽입하여 더 이상의 균열을 방지하는 공법 이외에도, 통상적으로 균열 혹은 파손된 도로포장층을 탈거시켜 동일소재, 예컨대 콘크리트를 다시 타설하는 방법을 사용하였으나, 추후에 타설된 콘크리트가 종래의 도로포장층과 견실하게 접착되지 못한다. 그러므로, 중하중의 차량이 급발진, 급제동으로 발생하는 충격과 진동으로 타설된 콘크리트가 제기능을 발휘하지 못하고 별리(別離)되는 단점을 가진다.In this way, in addition to the method of inserting a specific article into the road pavement layer to prevent further cracking, the method of removing the cracked or damaged road pavement layer is usually used to re-pour the same material, for example, concrete. Concrete does not adhere firmly to conventional pavement layers. Therefore, a heavy-loaded vehicle has a disadvantage in that concrete poured by shock and vibration generated by sudden start and sudden braking does not function properly and is separated.

이에 본 발명은 상기와 같은 문제점을 해결하기 위해 창출된 것으로, 통상적으로 콘크리트 또는 아스팔트 등으로 도포된 포장도로면은 과중량의 차량이 차도에서, 특히 교차로와 같이 차량의 출발과 정지가 빈번하게 발생되는 노면에서 급발진, 급제동 혹은 자연적 기후특성에 기인한 우수(雨水)와 급격한 기온의 변화로 피로와 파괴현상이 야기된다. 이와 같이, 노면의 변형을 방지하기 위해서 본 발명은 노면의 파손을 방지하기 위해 노면가설단계에서 시행할 수 있을 뿐만 아니라 노면변형이 발생된 부분에서도 시행가능하게 되어 있는데, 균열부의 방지와 보수를 필요로 하는 노면의 일부에 취성을 갖는 콘크리트의 약점을 극복하기 위해 포장층과의 접착력을 향상시켜 노면포장층이 별리되지 않도록 결합강도를 증대시키기 위해 노면을 특수한 형상으로 되게 한다.Accordingly, the present invention has been created to solve the above problems, the surface of the pavement road is usually coated with concrete or asphalt, etc., the vehicle of heavy weight frequently occurs in the roadway, especially the start and stop of the vehicle such as an intersection On the road surface, fatigue and destruction are caused by rain and sudden changes in temperature due to sudden oscillation, sudden braking or natural climatic characteristics. Thus, in order to prevent the deformation of the road surface, the present invention can be implemented not only in the road construction step to prevent the road surface damage but also in the part where the road surface deformation has occurred, it is necessary to prevent and repair the cracked portion. In order to overcome the weakness of concrete having brittleness on a part of the road surface to improve the adhesion with the pavement layer to make the road surface in a special shape to increase the bonding strength so that the road pavement layer is not separated.
