Description

一种高效市政施工砂石筛选设备 技术领域
本发明涉及一种市政领域，具体是一种高效市政施工砂石筛选设备。
背景技术
市政工程是指市政设施建设工程。在我国，市政设施是指在城市区、镇(乡)规划建设范围内设置、基于政府责任和义务为居民提供有偿或无偿公共产品和服务的各种建筑物、构筑物、设备等。市政工程一般是属于国家的基础建设，是城市生存和发展必不可少的物质基础，是提高人民生活水平和对外开放的基本条件。砂石因其良好的硬度和稳定的化学性质，常常作为优质的建筑材料、混凝土原料而广泛应用于房屋、道路、公路、铁路、工程等领域。随着基础设施施工技术的要求和高科技的发展，对砂石的数量和质量都有了更高的要求。砂石属松散物，但其颗粒一般硬度较大，且在地表环境下，化学性质稳定。市政施工多处都需要混凝土，混凝土中占整个体积80％以上的砂、石料均就地取材，其资源丰富，有效降低了制作成本。根据使用功能要求，改变混凝土的材料配合比例及施工工艺可在相当大的范围内对混凝土的强度、保温耐热性、耐久性及工艺性能进行调整。拌合混凝土优良的可塑成型性，使混凝土可适应各种形状复杂的结构构件的施工要求。在混凝土结构中，砂石主要起骨架作用，稳定混凝土的体积，传递应力，同时抑制收缩，防止开裂。在建筑和基础设施中发挥着极其重要的作用，可以说没有砂石，就没有混凝土，也就没有混凝土建筑和基础工程。对不同尺寸的砂石具有不同的作用，现有的砂石筛选工作效率低下，难以满足日益繁华的生产生活的需要。
