| Zusammenfassung: | The present invention relates to an underpass joint construction method that minimizes plastic deformation and improves product durability, which is implemented to ensure vehicle safety and speed by increasing the rigidity of expansion joints so that plastic deformation of expansion joints does not occur while resolving a problem of waterproofing occurring in a space of an underpass slab superstructure and eliminating vibration and noise problems caused by passing vehicles by improving the flatness of a road surface at the same time. The underpass joint construction method of the present invention includes a cutting step of cutting and breaking a construction site of an underpass where a joint is to be constructed.
본 발명은 지하차도 슬라브 상부구조 공간에서 발생하는 방수상의 문제점과 노면의 평탄성을 개선하여 통행차량에 의한 진동이나 소음의 발생을 해소하는 동시에 신축이음재의 소성변형이 발행하지 않도록 신축이음재의 강성을 높임으로써 차량의 안전성이나 쾌속성을 확보할 수 있도록 구현한 소성 변형을 최소화하여 제품의 내구성을 향상시킨 지하차도 조인트 시공 방법에 관한 것으로, 조인트를 시공할 지하차도의 시공 부위를 절단 및 깨는 절단 단계;를 포함한다. |
