为提高隧道防排水技术的水平，实现喷涂式防水的定量化设计，以京张高铁东花园隧道工程为背景，研究了隧道喷涂式防水喷层厚度的影响因素，主要包括工程防水等级、设计使用年限、地下水状况、隧道纵坡方向、隧道所处环境及喷涂施工方式等；提出了喷涂式防水的定量化设计方法，基于隧道不同部位喷层厚度基本值与建议值，进行加权修正最终确定防水层厚度；提出适用于明洞隧道的全封闭喷涂速凝橡胶沥青防水体系，即“地表处理+衬砌结构自防水+喷涂防水层、保护层、找平层+接缝防水”，并成功应用于东花园明洞隧道防水设计中。研发了隧道自动化喷涂防水设备，通过电脑控制走行装置和喷涂机械手实现了喷涂防水施工自动化，替代传统人工喷涂方式，经实践证明机械喷涂效率为人工喷涂的4倍，检验防水合格率达到100%。

In order to improve the level of tunnel waterproof
and drainage technology and realize the quantitative design of spray type
waterproof, taking donghuayuan tunnel project of Beijing-Zhangjiakou high-speed
railway as the background, this paper studies the influencing factors of the
thickness of spray type waterproof coating, mainly including the engineering
waterproof grade, design service life, groundwater condition, tunnel
longitudinal slope direction, tunnel environment and spraying construction
method, etc The quantitative design method of waterproof is based on the basic
value and recommended value of spray layer thickness at different parts of the
tunnel, and the thickness of waterproof layer is finally determined by weighted
correction; a fully closed spraying quick setting rubber asphalt waterproof
system suitable for open cut tunnel is proposed, which is "surface
treatment + self waterproofing of lining structure + spraying waterproof layer,
protective layer, leveling layer + joint waterproof", and has been
successfully applied to the east garden Tunnel waterproof design. The tunnel
automatic spraying waterproof equipment was developed, and the spraying waterproof
construction automation was realized through the computer-controlled running
device and spraying manipulator, which replaced the traditional manual spraying
method. The practice shows that the mechanical spraying efficiency is 4 times
of the manual spraying, and the qualified rate of waterproof inspection is
100%.
