求翻译：罐内表面平整度要求较高，在找平层施工之前做好标高点的设置，每间隔2米是指一个标高控制点。同时，为防止浇筑混凝土过程中对标高标记点的破坏，进而造成找平的误差，要求在浇筑过程中对标高进行跟踪控制，具体操作方法：派出测量人员随时跟踪对标高进行复核检查。为了在浇筑过程中对标高进行复核的方便，采用分区域的方式进行浇筑，具体的操作方法为：是什么意思？

Higher surface roughness tank, well before the screed elevation point of the construction set, each interval of 2 m is a control point elevation. Meanwhile, in order to prevent the process of pouring concrete on the elevation of markers of damage, and cause leveling errors, requiring the pouring pro

High surface smoothness requirements within the tank, well before the screed construction sets marked high, 2 m per interval refers to a level of control points. At the same time, to prevent the destruction of the elevation point in the process of pouring concrete, thus leveling errors, require trac
