Multi-stage floating dust prevention method for concrete member in low vacuum-normal pressure alternating environment
The invention provides a multi-stage floating dust prevention method for a concrete member in a low vacuum-normal pressure alternating environment, which comprises a common concrete layer, an ultra-high performance concrete layer and a sealing coating layer or a fiber reinforced composite material layer. The common concrete layer is poured in the inner layer, the ultra-high performance concrete layer is poured on the surface of the common concrete layer, and the sealing coating layer is coated on the surface of the ultra-high performance concrete layer or the fiber reinforced composite material layer is laid on the surface of the ultra-high performance concrete layer. Common concrete and ultra-high performance concrete are combined for use, external protection of a coating or a fiber reinforced composite material is supplemented, the common concrete is a main stress component, and the ultra-high performance concrete is a covering surface layer. By reasonably configuring the sequence and dosage of all the materials on the fracture surface and fully exerting the advantages of all the materials, three floating dust prevention systems are formed, floating dust of concrete is inhibited fundamentally, and meanwhile the requirements for stress, abrasion resistance and high temperature resistance of a vacuum pipeline concrete member are met.
本发明提供了一种低真空‑常压交变环境下混凝土构件多级防浮尘方法，包括：普通混凝土层、超高性能混凝土层、密封涂料层或纤维增强复合材料层；普通混凝土层浇注于内层，超高性能混凝土层浇注于普通混凝土层表面，密封涂料层涂覆于超高性能混凝土层表面或纤维增强复合材料层铺设于超高性能混凝土层表面。将普通混凝土与超高性能混凝土进行结合使用，并辅以涂层或纤维增强复合材料的外防护，普通混凝土为主要受力构件，超高性能混凝土为覆盖面层。通过在断面上合理配置各材料顺序及用量，充分发挥各材料的优点，形成三道防浮尘体系，从根本上抑制混凝土的浮尘，同时满足真空管道混凝土构件受力、耐磨和耐高温的需求。
