丙烯酸球场在施工中对混凝土基础要求

?? ?发布时间:2020-07-21

  丙烯酸球场与硅PU球场不同的一点是丙烯酸球场对地面要求比较高,做丙烯酸球场的基础需要一定的标准。

  一、混凝土基础标号不低于C25,厚度高于或等于150毫米。同时,混凝土的排水要求要高,四周必须要有排水沟渠,基础结构中须有防潮层?;炷帘砻孀詈檬亲匀晃评?。

  若是由于场地的不同限制,浇筑素混凝土和钢筋混凝土都应该在适合的位置切割伸缩缝。

  混凝土做成后不可立即施工丙烯酸球场,须等待养护一个月后进行冲水处理才可动工。

  二、如果可以选择,最好选择沥青混凝土基础。沥青混凝土基础厚度须高于或等于70毫米,其中厚粗沥青混凝土的厚度须达到40毫米,厚细沥青混凝土厚度须达到30毫米,同样对排水要求较高,四周必须铺设排水沟渠,不需要切割伸缩缝。

  三、在天气好时只需要养护15天左右,正常天气一般养护28天。养护结束后用高压水枪对场地进行冲洗,将所有杂物尽可能地冲洗干净,用正常流程检查清楚后才可进行丙烯酸材料施工。若是场面脏污严重,须用5%的稀盐酸进行酸洗再重复一遍上述操作即可。

  四、混凝土施工要求:只可在中网下方的球场中心线处设置伸缩缝、排水坡度须达到5%,且须于中网方向的另一边平行排水、水泥混凝土表面不能够起粉且用直尺度量任一方向的两点间高度差不能够超过3毫米。
