Description

도로구조물의 신축이음부 시공방법{construction method of flexible connecting division of road-structure}Construction method of expansion joint of road structure {construction method of flexible connecting division of road-structure}

본 발명은 도로구조물의 슬래브와 슬래브 및 아스콘과 아스콘이 연결되는 부분에 팽창과 수축을 고려하여 설치되는 신축이음부에 관한 것으로, 더 상세하게는 새로 신설되거나 또는 균열이 생긴 신축이음부를 효과적으로 용이하게 시공할 수 있도록 하고, 또한 시공구조를 단순화하여 시공성을 높일 수 있도록 하며, 그리고 누수를 완벽하게 차단하는 동시에 유지보수가 용이한 도로구조물의 신축이음부 시공방법에 관한 것이다.The present invention relates to an expansion joint that is installed in consideration of expansion and contraction in the slab and the slab of the road structure and the connection between the ascon and the ascon, and more specifically, the newly formed or cracked expansion joints effectively The present invention relates to a method of constructing new joints of road structures that can be easily installed, and also to simplify construction, thereby improving workability, and to completely prevent leakage and to maintain maintenance.

일반적으로 지하차도나 하천복개 등 도로구조물의 구축 시에는 철근 콘크리트 구조로 된 슬래브와 슬래브를 서로 연결한 후, 슬래브의 상부에 아스콘을 포장하여 도로구조물을 형성하게 된다. 그러나, 이러한 도로구조물은 온도변화에 따라 팽창하거나 수축하게 됨으로써 파손이 발생하고, 슬래브와 슬래브 사이가 이격되는 경우에는 도로가 파손되므로 차량의 주행에 안전을 위협할 수 있는바, 이를 방지하기 위해 인접하는 슬래브와 슬래브 및 아스콘과 아스콘 사이에 신축이음부를 형성한 후, 이 신축이음부에 아스팔트나 실란트 등의 조인트를 설치하여 연결하고 있 다.In general, when constructing road structures such as underground roadways or river revetments, slabs made of reinforced concrete structures and slabs are connected to each other, and asphalt structures are paved on top of the slabs to form road structures. However, these road structures are damaged due to expansion or contraction due to temperature change, and when the space between the slab and the slab is separated, the road is damaged, which may threaten the safety of the driving of the vehicle. After the expansion joint is formed between the slab and the slab, and the asphalt concrete and the asphalt concrete, joints such as asphalt or sealant are connected to the expansion joint.

그러나 종래에는 도로구조물의 신축이음부에 단순히 아스팔트나 실란트 등의 조인트를 포설하여 시공하였기 때문에, 여름과 같이 기온이 올라가 도로구조물이 신장되면 신축이음부의 간격이 좁아지게 되고 그 사이에 포설된 조인트가 상부로 밀리면서 부풀어올라 둔턱이 생기게 될 뿐만 아니라 차량의 진행방향에 따라 조인트가 한쪽으로 쏠려 골이 파여지는 현상이 발생됨으로 차량의 통행에 큰장애물로 작용하게 되는 문제점이 있었다.However, in the past, simply install joints such as asphalt or sealant in the expansion joint of the road structure, so when the temperature rises in summer and the road structure is elongated, the interval between the expansion joints is narrowed and the joints installed therebetween. Was pushed to the upper side to not only swell, but also to create a barrier, as the joint is pulled to one side in accordance with the direction of the vehicle is a phenomenon that the bone is dug to occur, there was a problem that acts as a big obstacle in the passage of the vehicle.

또 겨울과 같이 기온이 내려가면 신축이음부의 간격이 넓어지게 되어 조인트는 넓어진 용적의 공간으로 분산되기 때문에 여름과는 반대로 오목한 요홈과 갈라짐이 발생되어 탈락되므로 역시 차량의 통행에 장애물로 작용하게 되는 문제점이 있었으며, 또한 이러한 문제점 발생 시 수시로 유지보수작업을 수행해야 하기 때문에 많은 인력과 시간 및 비용이 낭비되는 폐단이 있었다.In addition, when the temperature decreases as in winter, the space between the expansion joints becomes wider, and the joints are distributed to the space of the enlarged volume. There was a problem, and in addition, a lot of manpower, time and money was wasted because maintenance work had to be carried out from time to time.

한편, 상기와 같이 구축된 도로구조물은 설치기간이 경과함에 따라 구조물이 노후화되고 진동 등의 외부적인 힘에 의해, 특히 신축이음부에 균열이 발생하고 이 균열부위를 통해 누수가 발생하게 된다.On the other hand, the road structure constructed as described above, the structure is aging as the installation period elapses, and by the external force such as vibration, in particular, the crack occurs in the expansion joint and the leak occurs through this cracked portion.

이러한 신축이음부의 누수 발생 시 종래에는 조인트를 완전히 제거한 후, 슬래브와 슬래브 사이 신축이음부를 수시로 보수하였기 때문에 교통혼잡과 유지보수비용이 많이 발생되는 문제점이 있었다.In the case of leakage of such expansion joints, conventionally, after completely removing the joint, since the expansion joint between the slab and the slab is often repaired, there is a problem that a lot of traffic congestion and maintenance costs are generated.

또한 종래에는 신축이음부의 시공 시 상술한 바와 같이 거푸집을 설치해야 하는 관계로 시공구조가 복잡하여 시간적으로나 경제적으로 시공성이 크게 떨어지 는 문제점이 있었다.In addition, there is a problem in that the construction structure is complicated due to the need to install the formwork as described above when the expansion joint is constructed, the construction performance is greatly reduced in time and economics.

그리고 종래에는 신축이음부의 보수 시 조인트를 전체적으로 완전히 제거한 상태에서 다시 신축이음부에 전체적으로 조인트를 포설하였기 때문에, 구조적으로 수리 또는 교체작업이 매우 까다롭고 불편하여 유지보수가 용이하지 못한 문제점이 있었다.In the related art, since the joint is completely installed in the expansion joint in the state where the joint is completely removed when the expansion joint is repaired, there is a problem that the repair or replacement work is very difficult and inconvenient in structure, and thus the maintenance is not easy.

본 발명의 목적은 상기에서와 같은 종래의 결점을 해소하기 위해 발명한 것으로, 새로 신설되거나 또는 균열이 생긴 신축이음부를 효과적으로 용이하게 시공할 수 있도록 하고, 또한 신축이음부의 시공구조를 단순화하여 시공성을 높일 수 있도록 하며, 그리고 신축이음부의 누수를 완벽하게 차단하는 동시에 유지보수가 용이한 도로구조물의 신축이음부 시공방법을 제공하는데 있다.An object of the present invention is to invent the above-mentioned conventional drawbacks, to facilitate the construction of new or cracked expansion joints effectively and to simplify the construction of expansion joints In order to improve the workability, and to completely prevent the leakage of the expansion joints, and to provide a construction method for the construction of the expansion joints of the road structure easy to maintain.

이와 같이 구성된 본 발명의 신축이음부 시공방법을 첨부된 도면에 의거하여 공정별로 설명하면 다음과 같다.Referring to the process of construction of the expansion joint construction of the present invention configured as described above according to the accompanying drawings as follows.

(제1공정)(Step 1)

먼저, 도로구조물의 설치기간이 경과함에 따라 구조물이 노후화되고 진동 등의 외부적인 힘에 의해, 도 1a에서와 같이 신축이음부(1)와 조인트(10) 사이에 균열이 발생하고 이 균열부위를 통해 누수가 발생하면, 도 1b에서와 같이 균열이 생긴 신축이음부(1)의 기존 조인트(10)를 완전히 제거한 후, 조인트(10)가 제거된 신축이음부(1)를 압축공기와 고압 물청소를 이용하여 먼지와 이물질 등을 깨끗하게 제거한다.First, as the installation period of the road structure elapses, the structure ages, and due to external force such as vibration, a crack occurs between the expansion joint 1 and the joint 10 as shown in FIG. When leakage occurs through, as shown in Figure 1b, after completely removing the existing joint 10 of the expansion joint (1) cracked, the expansion joint (1) from which the joint 10 is removed is compressed air and high pressure water Use cleaning to remove dust and dirt.

이때, 도로구조물의 신설 시에는 기존의 조인트(10)를 제거하는 공정이 삭제되기 때문에, 새로 신설되는 도로구조물의 신축이음부(1)를 압축공기와 고압 물청소를 이용하여 먼지와 이물질 등을 깨끗하게 제거하면 된다.At this time, since the process of removing the existing joint 10 is deleted when the road structure is newly installed, the new joint portion 1 of the newly formed road structure is cleaned of dust and foreign substances by using compressed air and high pressure water cleaning. You can remove it cleanly.

(제2공정)(2nd step)

신축이음부(1)의 청소가 완료되면 도 1c에서와 같이, 슬래브(2)와 슬래브(2) 사이 슬래브이음공간(1a)에 백업재(20)를 압입하여 기밀하게 끼워 넣는다.When the expansion joint 1 is cleaned, as shown in FIG. 1C, the backing material 20 is press-fitted into the slab joint space 1a between the slab 2 and the slab 2 to be hermetically inserted.

(제4공정)(4th step)

슬래브이음공간(1a)의 상부에 차단판(30)이 설치되면 도 1e에서와 같이, 아스콘(3)과 아스콘(3) 사이 아스콘이음공간(1b)에 매트삽입공간을 남기고 봉합제(40)를 포설하여 경화시킨다.If the blocking plate 30 is installed in the upper portion of the slab joint space (1a), as shown in Figure 1e, leaving the mat insertion space in the ascon joint space (1b) between the ascon (3) and the ascon (3) suture (40) Install and cure.

이와 같이 아스콘(3)과 아스콘(3) 사이 아스콘이음공간(1b)에 봉합제(40)를 포설하여 경화시키면 아스콘이음공간(1)의 누수 및 부식을 방지할 수 있다.As such, when the encapsulant 40 is placed and cured in the ascon joint space 1b between the ascon 3 and the ascon 3, leakage and corrosion of the ascon joint space 1 can be prevented.

(제5공정)(5th process)
