Prefabricated UHPC (Ultra High Performance Concrete) surface protection structure for water delivery gallery of ship lock and construction method
The invention provides a ship lock water delivery gallery prefabricated UHPC surface protection structure and a construction method, and the structure comprises a gallery bottom wall surface protection structure which is located at the bottom wall of a water delivery gallery and is a cast-in-place UHPC concrete structure; the two gallery side wall surface protecting structures are arranged on the two side wall surfaces of the water conveying gallery correspondingly, and each gallery side wall surface protecting structure is composed of a plurality of prefabricated UHPC side plates; the gallery top wall surface protecting structure is located on the top wall of the water conveying gallery and composed of a plurality of prefabricated UHPC top plates, and the prefabricated UHPC top plates are erected above the two gallery side wall surface protecting structures. The UHPC prefabricated plate is used as the inner surface of the water delivery gallery by utilizing the characteristics of high durability, high mechanical property and good impact and wear resistance of the UHPC material, so that the structural durability of the water delivery gallery of the ship lock is greatly improved, the UHPC is used for protecting the water delivery gallery instead of impact and wear resistant concrete, the volume of the UHPC is about one twentieth of that of the impact and wear resistant concrete, and the service life of the water delivery gallery is prolonged. And the cost is about one fifth of that of anti-impact and wear-resistant concrete.
本发明提供一种船闸输水廊道预制UHPC护面结构及施工方法，包括：廊道底壁护面结构，位于输水廊道的底壁处，其为现浇UHPC混凝土结构；廊道侧壁护面结构，其数量为两个，分别设置在输水廊道的两个侧壁面处，廊道侧壁护面结构由多个预制UHPC侧板组成；廊道顶壁护面结构，位于输水廊道的顶壁处，其由多个预制UHPC顶板组成，预制UHPC顶板架设在两个廊道侧壁护面结构的上方。利用UHPC材料耐久性和力学性能高，抗冲磨性能好的特性，将UHPC预制板作为输水廊道内表面，大大提升了船闸输水廊道的结构耐久性，以UHPC替代抗冲耐磨混凝土用于输水廊道防护，体积约为抗冲耐磨混凝土的二十分之一，成本约为抗冲耐磨混凝土的五分之一。
