通常隧道防水板与土工布采用热风热熔焊接或吊带挂设工艺,施工质量受到工艺特点及人为因素的影响,质量控制难度大,存在焊焦、焊穿、焊接不牢固等质量通病.在玉磨铁路隧道施工中引进了新设备—防水板超声波焊接机进行防水板的施工,并在施工中对施工工艺进行了改进,使得防水板施工质量和施工工效得到质的提高,同时也使得施工成本大幅降低.%Usually the tunnel waterproof board and geotextile with hot melt welding or sling hanging process, the construction quality is affected by process characteristics and human factors, it is difficult to control the quality of welding coke, welding wear, unstable welding and other quality defects. In this paper, a new equipment, waterproof plate ultrasonic welding machine, is introduced in the construction of the Yuxi-Mohan Railway, and in the construction, process has been improved, so that the construction quality and construction efficiency of the waterproof board has been improved, but also the cost of construction is greatly reduced.
