본 발명은 고속도로 등에 시공 설치되는 중앙분리대의 개량공법 및 그 장치에 관한 것이며, 더욱 상세하게는 콘크리트 방호벽 구조의 상부에 방현망을 설치한 구조의 중앙분리대 구조에서 방현망을 철거하고 콘크리트를 덧씌우는 방법으로 기존 중앙분리대를 개량하는 공법과, 상기 중앙분리대를 개량함에 있어서 기존의 콘크리트휘니셔 사용하여 연속적으로 덧씌우기 공정을 수행할 수 있도록 한 콘크리트타설장치에 관한 것이다.The present invention relates to an improved construction method of the central separator installed in a highway and the like, and more particularly, to remove the anti-glare net in the central separator structure of the structure in which the anti-glare net is installed on the upper part of the concrete firewall structure and overlay the concrete. The present invention relates to a method for improving an existing median separator, and a concrete placing apparatus for performing a continuous overlay process using an existing concrete finisher in improving the median separator.

통상, 고속도로와 같은 자동차 전용도로에는 중앙선 침범사고를 방지하고, 반대차선의 전조등 불빛에 의한 시야 방해를 방지하기 위해 레일 또는 콘크리트 방호벽 구조의 중앙분리대가 설치되며, 대부분의 고속도로는 더 높은 안전성 확보를 위하여 콘크리트 구조의 방호벽으로 중앙분리대를 구성하고 있다.Typically, motorways such as highways are equipped with a rail or concrete barrier structure to prevent central line invasion and to prevent visibility from headlights of opposite lanes, and most highways provide higher safety. For this purpose, the central partition is composed of a concrete barrier.

통상적으로 고속도로에 설치되는 콘크리트 방호벽 구조에 의한 중앙분리대는 도 1에 도시한 바와 같이 노면으로부터 860mm 내외의 높이와 620~670mm 정도의 바닥 폭 구조의 콘크리트 옹벽 형태로 구성되며, 상부에 400mm 내외의 방현망(h)을 설치한 구조를 갖는다.Typically, the central separator with a concrete barrier wall structure installed on a highway is composed of a concrete retaining wall having a height of about 860 mm and a floor width of about 620 to 670 mm from the road surface, as shown in FIG. It has a structure in which a network h is provided.

이와 같은 종래의 중앙분리대 구조는 대형 차량의 경우 쉽게 월담하여 대향 차선으로 진입함으로써 대형 교통사고를 유발할 수 있고, 방현망 또한 전조등 불빛을 완전히 차단하지 못하여 야간 운전의 위험과 피로를 가중시키는 요인이 되고 있다.In the case of the conventional central divider structure, a large vehicle can easily enter the opposite lane by causing a heavy traffic accident, and the anti-glare network also does not completely block the headlights, which increases the risk and fatigue of night driving. have.

이와 같은 문제점 때문에 기존 중앙분리대의 노후화 추세에 맞추어 기존 중앙분리대를 철거하고 바닥부 폭을 700~720mm로 늘리고, 방현망이 불필요하게 높이도 대략 1270mm 로 높이는 새로운 규격의 중앙분리대를 설치하고 있다.Due to this problem, in accordance with the aging trend of the existing median separator, the existing median separator is dismantled, the width of the bottom part is increased to 700 ~ 720mm, and the anti-glare net is unnecessarily raised to a height of approximately 1270mm.

그러나 이와 같은 기존 중앙분리대를 철거하고 새로운 규격의 중앙분리대를 새로이 설치하는 방법은 많은 자원이 사용되고, 철거된 폐기물을 다량으로 양산하기 때문에 막대한 비용과 환경문제가 발생한다. 또한, 기간 교통망인 고속도로의 중앙 차로를 장기간에 걸쳐 차단하고 철거 및 시공이 이루어지기 때문에 교통난을 유발하는 문제점이 제기되고 있다.However, this method of removing the existing central separator and newly installing a new median separator generates a large amount of resources and generates a large amount of the removed waste, resulting in enormous cost and environmental problems. In addition, since the central lane of the highway, which is the main transportation network, is blocked for a long time and demolition and construction are carried out, a problem causing traffic difficulties has been raised.

본 발명은 기존의 콘크리트 방호벽을 철거하지 않고 덧씌움 보강하여 새로운 규격에 맞게 개량하는 공법을 새로이 제시함으로써 자원을 재활용하고, 폐기물의 발생량과 처리비용을 절감할 목적을 갖는다.The present invention has the purpose of recycling the resources, by reducing the amount of waste generated and disposal cost by newly presenting a method for improving to meet the new specifications by reinforcing the cover without removing the existing concrete firewall.

또한, 본 발명은 시공에 따른 교통통제를 최소화할 수 있도록 중앙분리대 개량공사를 신속하고 균일한 품질로 시공할 수 있도록 하는 장치를 새로이 제시할 목적을 갖는다. In addition, the present invention has an object of presenting a new device that can be installed in a quick and uniform quality improvement of the central separator to minimize the traffic control according to construction.

이를 위하여 본 발명은 기존 콘크리트 방호벽 상단에 설치된 방현망을 철거하고 벽체에 묻어 있는 이물질을 제거하는 사전처리공정과; 방호벽의 기초부와, 몸 체부 및 상단부가 포함되도록 일정 간격으로 앵커볼트를 매설하는 앵커볼트설치공정과; 상기 방호벽 외표면에 이격되게 와이어메쉬를 씌우고, 와이어메쉬를 각 앵커볼트에 고정하는 보강망설치공정과; 상기 보강망 외표면에 콘크리트를 덧씌움 하는 콘크리트 타설공정; 으로 이루어지는 콘크리트 방호벽 구조의 중앙분리대 개량공법을 제시한다.To this end, the present invention is a pre-treatment step of removing the anti-glare net installed on the top of the existing concrete firewall and remove the foreign matter on the wall; An anchor bolt installation step of embedding anchor bolts at regular intervals such that the foundation part, the body part and the upper end part of the barrier wall are included; A reinforcing net installation step of covering a wire mesh on the outer surface of the barrier wall and fixing the wire mesh to each anchor bolt; Concrete pouring process of overlaying concrete on the outer surface of the reinforcing network; We propose an improved construction method for the median partition of concrete barrier structure.
