본 발명은 높이 조정이 용이한 맨홀 보수 장치와 그 시공방법에 관한 것으로서, 보다 상세하게는 도로의 보강 포장시 포장재에 의해 뚜껑이 매몰되는 것이 방지되도록 뚜껑을 일정한 높이로 상승시킴에 있어, 포장재에 의해 고형화되게 고정된 맨홀 전체를 해제하지 아니하고 간편한 조작에 의해 뚜껑의 높이조절이 구현하도록 한 것으로 맨홀 보수시 높이 조절이 용이한 맨홀 보수 장치 및 그 시공방법에 관한 것이다.The present invention relates to a manhole repair device and a construction method thereof, the height of which is easy to adjust, and more particularly, to raise the lid to a certain height so that the lid is prevented from being buried by the pavement during reinforcement paving of the road. By manipulating the height of the lid by a simple operation without releasing the entire manhole fixed to be solidified by the present invention relates to a manhole repair device and a construction method that is easy to adjust the height during manhole repair.

일반적으로 지하 시설물의 설치 및 관리를 위해 설치되는 맨홀은, 지반에 매립된 관형의 몸체에 원판형 뚜껑이 안착하여 고정된 형태이다. 그리고, 작업자는 상기 맨홀을 통해 지하공간으로 투입되어 각종 지하 시설물의 설치 및 관리를 하게 된다. In general, the manhole installed for installation and management of underground facilities is a fixed form of a disc-shaped lid is fixed to the tubular body embedded in the ground. Then, the worker is put into the underground space through the manhole to install and manage various underground facilities.

따라서 상기 맨홀은 뚜껑이 외부에 노출되어 작업가가 개폐가 가능하도록 구성되어야 하는데, 도로는 최초공사 또는 노후 현상을 인해 도로표면이 고르지 못하게 되면 재차 아스콘이나 콘크리트 등 포장재를 덮어씌우는 보수공사를 행하게 된다. 이때, 도로상에는 상/하수도, 도시가스, 송유관, 각종 케이블 등의 맨홀 보수 공사도 동시에 수행하게 되는 것이다. Therefore, the manhole should be configured to be opened and closed by the worker is exposed to the outside of the lid, the road is to be repaired to cover the pavement such as asphalt or concrete again if the road surface is uneven due to the first construction or aging phenomenon. At this time, the manhole repair work such as water / sewerage, city gas, oil pipes, various cables, etc. are also performed on the road at the same time.

이러한 과정 중에 종래에는 지반에 고형화되게 고정된 맨홀본체를 해체한 다음, 해체된 공간의 하부 지반을 보강한 후, 맨홀을 재삽입하여 맨홀본체의 상부에 지반이 일정한 높이로 노출되도록 하고 있다. 이는 해제 및 재설치에 따른 부대비용이 증가하고 작업 인력 및 작업 시간이 많이 소요된다. During this process, the manhole body fixed to the ground is conventionally dismantled, and then reinforces the lower ground of the dismantled space, and reinserts the manhole so that the ground is exposed to a constant height on the upper part of the manhole body. This increases the cost of disassembly and reinstallation and requires a lot of manpower and time.

또한, 가변용 링을 사용하여 맨홀의 높이를 조절하는 방법이 있으나, 상기 가변용 링의 구조가 복잡하여 설치작업이 어려우며, 맨홀과의 밀착상태가 견고하지 아니하여 차량 통행으로 인한 소음 및 진동이 발생하는 문제점이 있다.In addition, there is a method of adjusting the height of the manhole using a variable ring, but the installation of the variable ring is complicated, and the installation work is difficult, and the close contact with the manhole is not solid, so that noise and vibration due to traffic of the vehicle are prevented. There is a problem that occurs.
