1.底漆处理：清理结构层和隔热层顶面上的松散碎屑。从基层表面突出的碎屑和其他碎屑应铲除，并且流平层的有效厚度不应受到影响。<br>2.堵塞管子的根部：大规模修整之前，必须妥善处理管子的根部等。<br>3.水泥砂浆找平层：施工前必须喷水以润湿基层表面，但切勿过度浇水；根据坡度要求，画线找到坡度，一般按高程1〜2m。铺平找平砂浆时，首先沿增强流的方向施压，确定找平层的分隔缝，宽度通常为20 mm，且该缝与绝缘层相连，分隔缝的最大间距为6米 <br>4.维护：浇水后24小时将流平层抹平并压实。一般加固期为7天。干燥后，铺设防水层。

1. Base coat treatment: clean up loose debris on the top surface of the structural layer and the insulation layer. Debris and other debris protruding from the surface of the base layer should be shoveled and the effective thickness of the leveling layer should not be affected. <br>2. Plugging the roots of the pipes: Before large-scale smoothing, the roots of the pipes, etc. must be treated well.<br>3. Cement mortar leveling layer: water must be sprayed to wet the surface of the base layer before construction, but excessive watering should not be used; according to the requirements of the slope, draw the line to find the slope, generally according to the elevation of 1 ~ 2 m. When spreading the leveling mortar, first press on the direction of the reinforcement flow and define the dividing joint of the leveling layer, the width is generally 20 mm and the joint is connected to the insulation layer , the maximum spacing of the dividing joint is 6 m. <br>4. Maintenance: the leveling layer is smoothed and compacted for 24 hours after watering. The general hardening period is 7 days. After drying, the waterproof layer is laid.

一。基层处理：清理结构层顶面及保温层的松散杂物。从基层表面伸出的杂物和其他杂物应铲除，不得影响找平层的有效厚度。<br>2。堵根：在进行大面积整平之前，必须对管道根部等进行良好的处理。<br>三。水泥砂浆找平层：施工前必须洒水湿润基层表面，但不得过度洒水；根据坡度要求，画线找坡，一般按标高1~2m摊铺找平砂浆时，先按钢筋流向确定找平层分格缝，宽度一般为20 m m，分格缝与保温层连接，分格缝最大间距为6 m。<br>四。养护：找平层浇水后24小时平整压实。一般硬化期为7天。干燥后铺设防水层。
