过去我段施工地道伸缩缝内贴止水橡胶板,是将橡胶板直按贴于伸缩缝内侧的阻水面上,再用螺栓将铁板固定。由于橡胶板与混凝土面不能充分密贴,止水效果不够理想,以致造成以后使用时渗漏的病害。为使地道伸缩缝内贴止水板充分起到预期的止水效果,我段1973年在滁县站地道以及最近在长淮卫(蚌埠东站)地道施工时均采用在橡胶板与混凝土阻 In the past, I built a section of tunnel joints rubber seal expansion joints, the rubber plate is pressed directly on the inside of the expansion joints on the water blocking surface, and then bolt the iron plate fixed. As the rubber sheet and the concrete surface can not fully close the sealing effect is not ideal, resulting in leakage after use of the disease caused. In order to ensure that the waterproof seal in the tunnel joints will fully exert the expected water-stopping effect, the section of tunnels in Chu County Station in 1973 and the recent tunnel construction in Chang-Huai Wei (Bengbu East Station)
