Novel seawater and sea sand concrete retaining wall structure and construction method
The invention relates to a novel seawater and sea sand concrete retaining wall structure and a construction method. The retaining wall structure comprises longitudinal fiber bars arranged on the two sides, fiber grids laid on the outer sides of the fiber bars, the fiber bars on the two sides are connected through the fiber bars and filled with seawater and sea sand concrete, and the outer side of the concrete is coated with a capillary crystalline coating. The construction method comprises the following steps: firstly, arranging longitudinal fiber bars on two sides, paving fiber grids on the longitudinal fiber bars, connecting the fiber grids by adopting the fiber bars, forming a reinforcing system by a concrete admixture and salt-containing components in seawater, preparing seawater and sea sand concrete, pouring and filling the concrete, and curing for 28 days. And spraying the prepared capillary crystalline material on the surface of the concrete for 2-4 times. Fiber materials replace steel bars to prevent seawater and sea sand corrosion; the longitudinal fiber bars are fixed by the fiber grids, so that the crack resistance, bending resistance and shearing resistance of the wall body are improved; salt-containing components in seawater and sea sand stimulate and improve the performance of the admixture and improve the strength of the concrete, and the seawater and sea sand concrete uses local materials and saves fresh water resources; the surface coating enhances the surface concrete, prevents the concrete surface from being corroded and peeled off, and improves the use durability of the concrete.
本发明涉及一种新型海水海砂混凝土挡墙结构及施工方法，挡墙结构包括两侧配有纵向纤维筋，纤维筋的外侧铺设纤维格栅，两侧纤维筋用纤维筋连接，内充填海水海砂混凝土，混凝土外侧涂有渗透结晶涂层。施工方法包括先设置两侧纵向纤维筋，在纵向纤维筋上铺设纤维格栅，纤维格栅之间采用纤维筋连接，混凝土外加剂与海水中含盐组分形成增强体系，配制海水海砂混凝土，浇筑充填混凝土，养护28天后，用配制好的渗透结晶材料对混凝土表面喷涂2‑4遍。纤维材料代替钢筋防海水海砂腐蚀；纤维格栅固定纵向纤维筋，提高墙体抗裂、抗弯和抗剪性能；海水海砂中含盐组分激发、提高掺合料的性能，提高混凝土强度，海水海砂混凝土在于就地取材，节约淡水资源；表面涂层增强表面混凝土，防止混凝土表面侵蚀剥落，提高混凝土使用的耐久性。
