在浇筑大面积预拌混凝土后,为防止混凝土中的水分蒸发造成混凝土干缩裂缝,一般都要对其采取养护措施,最常用的办法是在浇筑的混凝土初凝后,在混凝土表面覆盖塑料薄膜,因为一卷一卷的塑料薄膜要用人工铺设,在铺设塑料薄膜时人要弯腰在混凝土表面上操作,若铺设的面积大则非常辛苦,若注意力不集中或操作不当,塑料薄膜有可能铺歪、铺斜,不能有效地覆盖和搭接,对露出的混凝土表面的缝隙还要重新铺一层,既浪费材料又浪费人工和时间,怎样才能解决这个问题呢?
After pouring a large area of ready-mixed concrete, in order to prevent concrete from evaporating water caused by concrete shrinkage cracks, they generally have to take conservation measures, the most common approach is to pour concrete pouring concrete, the surface covered with plastic film , Because the volume of a roll of plastic film to be manually laid in the laying of plastic film, people bent over the concrete surface to operate, if the laying of the area is very hard, if inattention or improper operation, the plastic film has It may be crooked, slanting, can not effectively cover and overlap, the exposed concrete surface of the gap but also re-paving, both waste of materials and a waste of man-hours and time, how can we solve this problem?
