Research on the Promotion of Wet-Mix Shotcrete Technology in Water Diversion Tunnels of Hydropower Stations
水电站引水隧道湿喷混凝土工艺推广研究

摘要

本文通过对混凝土潮喷与湿喷工艺、质量、成本等全方位对比，论证了混凝土湿喷工艺的技术优势及在引水隧道工程中推广的必要性。湿喷工艺在混凝土匀质性、强度保障等方面优势显著，虽然与潮喷工艺相比成本更高，但是能有效提升混凝土强度，具有较高的性价比。因此在引水隧道工程施工中，湿喷工艺的应用可以实现安全、高效、耐久的建设目标，值得在行业内推广与应用。希望通过本文分析，能让人们了解与熟悉湿喷工艺，并能推动行业内对湿喷工艺的引进与应用，保证水电站引水隧道的质量与效率，推动行业的可持续发展。

Abstract

Through a comprehensive comparison of dry-mix and wet-mix shotcrete in terms of construction process, quality, and cost, this paper demonstrates the technical advantages of wet-mix shotcrete and the necessity of promoting its application in water diversion tunnel projects. Wet-mix shotcrete exhibits significant advantages in concrete homogeneity, strength assurance, and related performance aspects. Although its cost is higher than that of dry-mix shotcrete, it can effectively improve concrete strength and offers a relatively high cost-performance ratio. Therefore, in the construction of water diversion tunnels, the application of wet-mix shotcrete can help achieve the goals of safety, efficiency, and durability, and thus deserves wider promotion and application within the industry. It is hoped that this study will enhance understanding and familiarity with wet-mix shotcrete technology, promote its adoption and application in the industry, ensure the quality and efficiency of hydropower station water diversion tunnels, and contribute to the sustainable development of the sector.
