浅谈隧道防水板超声波焊接及质量控制要点

摘要

The tunnel flashing uses traditional hot melt welding, its construction efficiency is low and the welding quality and appearance are poor. Combined with the application of the welding technology of a new type of ultrasonic flashing in Banlun tunnel of the Napo Expressway from Guning, Yunnan to Napo, Guangxi, this paper analyzes the results from principle, process, organization, quality and other aspects. The indicators and performance advantages are obvious, which provides the reference for the application of ultrasonic flashing welding in the engineering.%隧道防水板使用传统的热熔焊接施工效率低,焊接质量和外观效果差,本文结合云南富宁至广西那坡高速公路板仑隧道采用新型超声波防水板焊接技术的应用情况,从原理、工艺、组织、质量各个方面的效果进行了介绍和对比,其指标和性能优势明显,对防水板超声波焊接在工程中应用有积极的借鉴作用.
