一、穿过屋顶防水层的管道、预埋件、设备基础等均应在屋顶防水层施工前埋设和安装完毕；
First, through the pipeline, the waterproof layer and equipment foundation shall be embedded in the construction of waterproof layer and buried before installation;
二、下层排水坡度应符合设计要求；
Two, the grass roots drainage slope should meet the design requirements;
三、管道与结构之前的缝隙应用细石混凝土或聚合物屋顶防水砂浆堵严；
Three, the gap between the pipe and the structure before the application of fine stone concrete or polymer waterproof mortar blocking;
四、对当天施工的基面进行清理，下层要坚固、无酥松、起砂与凹凸不平，要求基面干净，可以潮湿，但不得有明水、油污、杂物和其他可能破坏屋顶防水层的材料，下层外观显明凹凸不平时宜先用水泥砂浆找平；
Four, to clean up the base day construction, basic to strong, crisp, no sand and uneven surface, require clean, can be wet, but can not have water, oil, and other debris may destroy the waterproof layer material, the surface of the base is obviously uneven advisable to use cement mortar;
五、雨水口、施工缝、阴阳转角、管根、设备基础等必要进行局部增强处理的，应用手刮式液体橡胶屋顶防水涂料浸涂70-80g/m2短纤维针刺无纺布粘贴。
Five, rain mouth, construction joints, and the Yin and Yang corner, Guan Gen, equipment foundation, etc. need to be locally reinforced treatment, the application of hand scraping liquid rubber waterproof coating dip coating 70-80g/m2 short fiber.
步骤Step;
双组分（喷涂型）其A组分（液料）与B组分（液料）是由专用喷涂速凝设备，按设定好的比例、压力等进行喷涂作业不锈钢闸阀，3-5s固结成膜。适用于暗挖隧道拱顶等未便于涂抹施工的部位及大面积屋顶防水施工。
Two component (spray type) of its A component (liquid material) and B component (liquid material) is by special spray quick setting equipment, according to set a good proportion, pressure and other spraying operations, 3-5s consolidation into a film. Applicable to the roof of the tunnel excavation is not easy to smear the construction site and the large area of waterproof construction.
在大面积喷涂前应等到附加层悉数成膜后进行，先检查喷涂机的完备性、喷涂机的喷枪是否清洁以及质料传输管、滤网、阀门，并检查喷涂机是否可以正常工作。喷涂作业应分区施工并预先做好遮挡工作。调整好喷嘴与基面距离、角度及喷涂设备压力以求达到喷涂后的材料外观夹带，不露底且薄厚均匀。
In the large area before spraying should wait until after the film all the additional layer, first check the integrity of the spraying machine, spraying machine gun is clean as well as the raw material transmission tube, filter, valve, and check whether the spraying machine can work normally. Spray work should be partition construction and pre do block work. Adjust the distance and angle of the nozzle and the base pressure and spraying equipment in order to achieve the material surface entrainment after spraying, and do not show uniform thickness.
