如何保证隧道喷射混凝土的质量

摘要

对隧道喷射混凝土的四种施工工艺作了介绍，结合工程实例，从工艺选择、配合比设计、混凝土拌制、喷射作业要求等方面阐述了隧道喷射混凝土的质量控制措施，以确保隧道喷射混凝土的整体质量。%The oaoer introduces the four construction crafts of the tunnel shotcrete,and illustrates the quality control measures for the shotcrete from the craft selection,orooortion ratio,concrete manufacturing,shotcrete working demands,so as to ensure the integrated quality of the shot-crete.
