Water filtering concrete suitable for water taking structure of seepage channel of silt-laden river and preparation method of water filtering concrete
The invention discloses water filtering concrete suitable for a water taking structure of a silt-laden river seepage channel and a preparation method of the water filtering concrete. 1m < 3 > of the water filtering concrete comprises the following components: 350-450kg of a cementing material, 700-950kg of coarse aggregate, 600-800kg of fine aggregate, 95-135kg of water, 5-7kg of a water reducing agent and 1-2kg of a modified material, wherein the water-binder ratio is 0.26-0.32. The prepared water filtering concrete not only can enable the water taking structure of the infiltration canal to meet the requirement for the filtering effect of a silt-laden river, but also is high in filtering capacity and large in water taking amount, can meet the requirement for water taking of engineering construction, and can enable the water taking structure of the infiltration canal to have good anti-blocking performance, so that the service life of a water taking system of the infiltration canal is prolonged; besides, local materials are used for preparing the aggregate of the water filtering concrete, so that the problem of shortage of natural aggregate in plain areas is solved, the resource utilization approach of sediment is expanded, and ecological protection and high-quality development of sediment-laden river basins are facilitated.
本发明公开了一种适用于多泥沙河流渗渠取水结构的滤水混凝土及其制备方法，1m3滤水混凝土包括以下组分：胶凝材料350‑450kg、粗骨料700‑950kg、细骨料600‑800kg、水95‑135kg、减水剂5‑7kg、改性材料1‑2kg，水胶比＝0.26‑0.32。所制得的滤水混凝土不仅可以使渗渠取水结构满足多泥沙河流过滤效果的要求，并且过滤能力高、取水量大，可满足工程施工取水的要求，还可以使渗渠取水结构具有较好的防堵塞性能，进而提高渗渠取水系统的使用年限；此外，就地取材制备滤水混凝土的骨料，不仅解决了平原地区天然骨料短缺的问题，还拓展了泥沙的资源化利用途径，有助于多泥沙河流流域的生态保护和高质量发展。
