Ultra-high-performance concrete protection layer of PCCP, pouring equipment and pouring method
The invention discloses an ultra-high-performance concrete protection layer of a PCCP (prestressed concrete cylinder pipe), pouring equipment and a pouring method, and solves the technical problem that because the protection layer of the PCCP in the prior art is influenced by the type and manufacturing process of the protection layer, in corrosive soil, the PCCP protection layer cannot meet the durability requirement that the service life is greater than or equal to 50 years under the condition of not adopting additional anti-corrosion measures. The invention provides the ultra-high performance concrete protection layer of the PCCP, the pouring equipment and the pouring method. According to the ultra-high-performance concrete protection layer of the PCCP, on the basis that the thickness of the protection layer is reduced by 20%, the durability index that the service life is 100 years in the E-grade corrosion environment can be met without any other additional anti-corrosion measures, and therefore the problem that the corrosion resistance is short is solved from the PCCP.
本发明公开了一种PCCP管道的超高性能混凝土保护层、浇筑设备及浇筑方法，解决了现有技术中的PCCP管道的保护层因其本身种类与制作工艺的影响，使得在腐蚀性土壤中，PCCP管道保护层在不采用附加防腐措施的条件下无法满足使用年限≥50年的耐久性要求的技术问题。它包括一种PCCP管道的超高性能混凝土保护层、浇筑设备及浇筑方法。本发明提供的PCCP管道的超高性能混凝土保护层可以在减少20%保护层厚度的基础上，无需其它任何附加防腐措施即可满足在E级腐蚀环境下使用年限100年的耐久性指标，从而从PCCP管道本身解决了耐腐蚀性能短板问题。
