公路桥梁隧道工程施工防水设施应用

Application of Waterproof Facilities in the Construction of Highway Bridge and Tunnel Engineering

为解决现有公路桥梁隧道工程施工中防水设施防水性能差的问题,开展相关研究,通过建立隧道新型防水系统模型,设计了隧道结构细部防水构造,布置了隧道排水沟,实现了对防水设施应用创新。通过实证分析得出,新的应用方案可以实现对渗透系数的控制,保证了工程项目的弱透水性,达到了理想防水效果。

In order to solve the problem of poor waterproof performance of waterproof facilities in the construction of existing highway bridge and tunnel engineering projects,relevant research has been carried out.By establishing a new type of waterproof system model for tunnels,the detailed waterproof structure of tunnel structures has been designed,and tunnel drainage ditches have been arranged,achieving innovation in the application of waterproof facilities.Through empirical analysis,it is concluded that the new application scheme can control the permeability coefficient,ensure the weak permeability of the engineering project,and achieve the ideal waterproof effect.
