Waterproofing reinforcement structure of underground structure expansion joint and constructing method thereof
The present invention provides a waterproofing reinforcement structure for an expansion joint of an underground structure and a construction method thereof, wherein the waterproofing reinforcement structure for an expansion joint of an underground structure forms a V-shaped groove in a longitudinal direction on an upper portion of a drain bar inserted into the expansion joint to which structures of the underground structure are connected and has a groove shape on a waterproof sheet attached to the upper portion to have an expansion function while moved with the drain bar, thereby allowing the waterproof sheet to absorb an expansion length even when contraction or expansion is generated on the structure in accordance with outdoor temperature. Thus, the waterproofing reinforcement structure for an expansion joint of an underground structure can prevent damage to the waterproof layer.
본 발명은, 지하구조물의 구조물과 구조물이 이어지는 신축이음부에 삽입되는 드레인바의 상부에 길이방향으로 '∨'형 홈을 형성하여 그 상부에 부착하는 방수시트에도 홈 형상이 형성되어 드레인바와 함께 움직이면서 신축 기능을 갖도록 함으로써, 외기온도에 따라 구조물에 수축 또는 팽창이 발생하더라도 방수시트가 그 신축량을 흡수할 수 있게 하여 방수층의 파손을 방지할 수 있는, 지하구조물 신축이음부의 방수 보강구조 및 그 시공방법을 제공하기 위한 것이다.
