Description

基础采用透水混凝土的塑胶跑道及其施工方法 技术领域
本发明属于运动场塑胶跑道技术领域，具体是一种采用透水混凝土的塑胶跑道以及该跑道的施工方法。
背景技术
目前，运动场塑胶跑道的基础层一般是使用传统水泥混凝土基础层或沥青基础层。传统的混凝土基础层施工难度大、平整度难以掌握，容易起砂，与塑胶面层粘接不牢，夏天经太阳暴晒后表面温度高达70℃以上，高温会加速塑胶面层老化，塑胶面层在高温下容易分解出有害气体，产生刺激性气味。沥青基础层必须用大型机械施工，小场地无法采用沥青机械施工，夏天高温天气沥青基础层不易散热，导致塑胶面层温度容易升高，同样会加速面层老化，高温中塑胶跑道的有害物质容易分解，对周围环境造成危害。
另外，由于塑胶跑道的基础都是由水泥混凝土或沥青混凝土做成的，其排水系统是通过其表面排水，流入跑道周边砌成的水沟，设计时路面要求有一定的坡度以便雨水流向水沟排出，在施工时还要注意防止水泥混凝土起砂，表面不能凹凸不平，以防积水造成塑胶跑道面层浸泡在水中，给塑胶跑道面层带来影响，缩短其使用寿命。即使是沥青混凝土也要注意其中石腊的含量，石腊多了容易造成面层粘接不牢。
发明内容
为解决传统塑胶运动场地基础层施工难度大，塑胶层在烈日下温度容易升高导致易老化，表面不平时容易积水等问题，本发明提出一种采用透水混凝土作为塑胶跑道的基础层，以及透水混凝土塑胶跑道的施工方法。其技术方案如下：
基础采用透水混凝土的塑胶跑道，包括地基层、基础层和铺设在基础层上面 的塑胶层，所述基础层为透水混凝土层，所述塑胶层与透水混凝土层之间通过胶水连接和固定。
作为本发明的优选技术方案，所述塑胶层包括混合型塑胶层或透气型塑胶层，所述胶水渗透入透水混凝土层的上部形成胶水渗透层。
作为本发明的优选技术方案，所述透水混凝土设有10％-25％的孔隙。
作为本发明的优选技术方案，所述透水混凝土的胶水渗透层厚度为1.5毫米至3.5毫米。
作为本发明的优选技术方案，所述透水混凝土的胶水渗透层设有5％-15％的孔隙。
一种塑胶跑道的透水混凝土基础层，其配比按每立方米质量组份计为：砂石1650kg，高标号硅酸盐水泥300-400kg，环保型减水剂1.5-5kg，硅粉3-10kg，纤维素0.5-1.5kg，可再分散性乳胶粉1-3kg，水100-150kg。
作为本发明的优选技术方案，所述透水混凝土的配比中环保型减水剂为2.5kg，硅粉为5kg，纤维素为1kg，可再分散性乳胶粉为2kg，水120kg。
作为本发明的优选技术方案，所述砂石的粒径为3毫米至40毫米；所述纤维素采用粘度为10万厘泊以下的纤维素，所述高标号硅酸盐水泥采用600以上标号的硅酸盐水泥。
一种透水混凝土塑胶跑道的施工工艺，包括以下步骤：
(1)将透水混凝土基础层所需原材料用强制式搅拌机充分拌合，通过运输车辆送入施工场地，现场浇筑透水混凝土基础层，并在20分钟内将同一批次拌合的所有原料使用完毕；
(2)对透水混凝土基础层进行人工刮平，然后机械抛光；
(3)检查透水混凝土基础层的平整度，对凹凸部位进行找平；
(4)底胶铺设，机械铺设橡胶颗粒层的厚度为10-12毫米；然后进行面胶摊铺，刮胶时使成胶速度均匀一致；
(5)刮面胶，在面胶未固化前，撒上红色颗粒，待其完全固化后，将多余面胶粒清扫干净；
(6)喷胶，确保橡胶颗粒不脱落。
作为本发明的优选技术方案，所述步骤(6)采用机械单方向喷涂面胶，然后再反方向喷涂一遍，使得面胶层厚度达到1.5毫米。
本发明的有益效果如下：
1、采用透水混凝土作为基础结构，能延长塑胶跑道的使用寿命，透水混凝土的多孔结构与塑胶跑道面层粘接，结合牢固，不易起层脱落，加上透水混凝土结构有15％的孔隙，在烈日下其表面温度比传统混凝土路面温度低10℃-20℃，从而能够有效延缓塑胶跑道面层的老化。
2、相对于传统基础层上做混合型塑胶跑道或密闭型塑胶球场，对基础的施工要求很高，底层必须要做防水层，还要测试混凝土面层的含水量，否则容易导致脱层起壳现象，面层粘接不牢，从而产生施工质量问题。
本发明在混合型塑胶跑道或其它塑胶场地施工过程中，因透水混凝土表面多孔，上第一遍塑胶面层时，胶水材料能够渗透进透水混凝土基础层2到3毫米，与混凝土粘结形成整体结构，使塑胶面层更加牢固，加上基础层有透水透气的作用，在高温环境下水汽含在透水混凝土中，不会把塑胶面层拱抬起来。本发明能够降低施工难度，从而有效保证跑道塑胶面层的施工质量。
3、本发明降低了塑胶跑道小范围的热岛效应，并能减少投资，跑道不会产生积水，雨停后即可使用跑道。如果采用透气型塑胶面层，既能在高温天气降低塑胶层的温度，又可以实现良好的排水性能，下雨时也能使用跑道，提高了跑道的利用率。
4、本发明应用范围广泛，可以应用于运动场跑道、球场、公园步道、人造草坪等，塑胶面层或人造草坪覆盖在透水混凝土基础结构上面，多孔结构使其透气透水性好，降低塑胶面层的表面温度，提高运动场地塑胶面层与基础的粘 接强度，从而大大延长塑胶跑道的使用寿命。
