如何判断硅PU球场基础是否达标

发布日期:2020-11-09 11:12 浏览次数:

 

 

一.判断基础情况的基本要领如下:

   1、要看完全场;
   2、从多个方面了解基础方面的信息;
   3、及时反映发现的问题;
   4、找出眼观较难发现的问题。

  二. 硅PU球场施工前,混凝土基础要注意以下细节:

  1. 混凝土基础保养情况
  做硅PU球场至少基础保养28天才适合做。混凝土基础的标号是否够,是否存在起砂起粉的情况。

   判断方法:
   ①、问基础标号。
   ②、用硬质的小工具刮看刮痕深度,越深标号越低。

   ③、如下了雨,然后刚晴起来不久,看基础的干湿,基础颜色深浅情况,干湿深浅不一,积水除外,存在局部或 大部分起砂的情况。 


  2. 是否存在起壳现象
   判断方法:
   ①、比较严重的眼睛直接看得出来。
   ②、踩、敲、用硬点的扫把扫等听到空响声,则有起壳的地方。

   ③、一般不是专业做运动场人员修补的地方,起壳的概率很大的,看是否有修补的地方也可以判断是否会存在起壳。

   ④、问,问基础是否是在原基础上薄薄的打了一层,是的话,以后基础起壳风险也很大

   ⑤、如过遇到基础表面很光亮,硬度也很大,一般这种情况是原基础起沙,混凝土标号不够,后来再处理的,以后起壳可能性也是非常大的。
              

   3.基础表面平整情况
   判断方法:
   ①、眼观,有积水,则需要修补,基础面粗糙,做不起来厚度,凹凸小平面多,则费料,验收方面很难达标。
   ②、测,可以拉线或直棒测平整度测积水状况。

   4.是否开裂或存在开裂的情况
   判断方法:
   ①、看是否已经有开裂的情况。
   ②、是否按要求开伸缩缝。
   ③、大面积场地是否有伸展缝。
   ④、板块接缝一般会开裂。
   ⑤、沟盖板补的地方是否有开裂迹象。
   ⑥、问或看混凝土地基情况,地基松软或未夯实,基础沉降可能性较大。

   5.测基础大小

  看大小是否足够运动场划线,非专业人士或场地受限, 是有可能出现大小不合适的情况,需要沟通好划线规划。


   三.硅PU球场施工前,沥青基础要注意以下细节

  1. 看密实度
   沥青基础,沥青颗粒是否夯实压密实,不密实封沥青基础容易出些问题。

  2. 看平整度

   沥青基础是否有起伏,凹凸不平,封沥青基础后 ,积水深了大了,补的成本较高,下降太深积水会导致面层龟裂。

   3.看地基情况
   沥青基础下面地基是否属于软质或沙地,这种情况易出现沥青基础不平整,或以后沉陷。

   4.看排水沟情况
   排水沟盖板不能高于沥青基础或低得太多。

  5. 看积水情况
   沥青下面不能有大的深的积水,混凝土将沥青基础围上,关水在沥青基础里。

   6.看基础连贯性
   沥青基础是否有断缝,脱层松散情况。

   硅PU球场基础的好坏,直接关系到球场完成后的使用效果及美观。因此球场基础的判断尤为重要,根据不同基础情况采取不同处理措施,才能造就完美的硅PU球场。
