Description

一种环保型透水砖
技术领域
本发明涉及海绵城市透水路面施工领域,尤其涉及轻型交通道路透水路面的一种环保型透水砖。
背景技术
玉溪东风广场、中山岐江公园、武汉豹子溪、成都杉板桥公园等近十个海绵城市大量采用透水砖形成生态整体透水路面,全国一、二线城市的小区道路、广场、公园、人行道对透水路面的需求量非常大。
现有的部分透水砖其强度值与渗透系数存在一定的对立关系,强度的增加往往伴随着孔隙率和渗透系数的降低,大都以孔隙率大小以及数量多少来保证透水速率,但随着时间的推移,孔隙堵塞引起透水速率迅速降低,难以保证在结构寿命周期内继续使用。
发明内容
本发明提供了一种环保型透水砖,涉及路砖技术领域,可应用于轻型交通道路透水路面。
为实现上述环保型透水砖的生产,采用的技术方案如下:一种环保型透水砖,以重量配比的组分组成计,原材料为:中砂29-44份,亲水性环氧树脂2.6-4份,固化剂0.4-0.7份,着色剂0.4-0.6份,玄武岩石子27-40份,建筑垃圾骨料11-17份,水泥10-15份,水4-6份,玄武岩纤维0.3-0.5份。
上述环保型透水砖中,中砂为石英砂,粒径为0.5-2mm的级配砂。
上述环保型透水砖中,绿色着色剂选用氧化铜,红色着色剂则选用三氧化二铁。
上述环保型透水砖中,亲水性环氧树脂为聚丙烯树脂YS830。
上述环保型透水砖中,玄武岩石子、建筑垃圾骨料为2-5mm的级配碎石。
上述环保型透水砖中,水泥采用P·O42.5的普通硅酸盐水泥。
上述环保型透水砖中,玄武岩纤维抗拉强度4000-4800MPa,断后伸长率3.1%,长度6-12mm,直径9-13μm。
上述环保型透水砖尺寸采用300mm×300mm×60mm,采用搭接构造形式,见图1。
所述的环保型透水砖采取上下块搭接的形式构成,上块和下块重合一半,在所述的重合部分设置有竖向的钢纤维,增强上下块的连接强度。
进一步的,在所述的下块的上表面上均布若干个凸起,所述的凸起设置在未重合部分,且凸起为锥台,所述的锥台靠近下块上表面的面积大于远离上表面的面积,所述的凸起的高度为上块高度的一半,同样,在上块下表面与凸起对应的位置上设置凹槽,凹槽截面也是锥台形状,下块的凹槽面积沿深度不断减小,其大小和凸起锥台相对应。
进一步的,在所述的锥台形的凸起表面的顶端部设置有软性的钢丝,同样在锥台形状的凹槽与锥台形凸起设置钢丝对应处设置有小孔,在两相邻的环保型透水砖拼接时,钢丝能插入到小孔内增强连接强度;
进一步的,为了方便钢丝插入到小孔内,所述的凸起的顶端四角可打磨成圆弧状,所述的凸起的高度略微比凹槽的深度小一点,方便在插接过程中凸起有一定的可活动的空间。
进一步的,在所述凹槽中心位置处设置有贯穿上块的孔洞,所述的凸起底部四周设置有若干贯穿下块的孔洞;
进一步的,在拼接相邻两环保型透水砖时,在孔洞内灌注砂浆,增强钢丝和小孔的连接强度。
所述的上下块设置有贯穿的孔洞,在所述的孔洞内填充透水材料,所述的透水材料优选聚合物纤维多孔混凝土或透水性沥青混合料。
所述的环保型透水砖的制备方法:按上述组分,采用搅拌装置,先使水与水泥搅拌均匀,再加入玄武岩石子、建筑垃圾骨料、玄武岩纤维,搅拌3分钟,倒入模具内,压力机1.0MPa的压力下静压30s,再在另一个搅拌装置倒入亲水性环氧树脂、固化剂、中砂、着色剂搅拌3分钟,倒入模具内,压力机1.0MPa的压力下静压30s,自然养护成型。
附图说明
图1为本申请的环保型透水砖结构示意图,附图说明:1,下块;2,上块;3,锥台;4,凹槽。
