喷射混凝土支护工程的质量,主要取决于喷射混凝土的强度、喷射混凝土与岩层的粘结力以及喷射混凝土的厚度等因素,因此,对这些因素的质量控制是非常重要的。 一、喷射混凝土强度的控制 强度是一个反映喷射混凝土支护质量全貌的指标,实际施工中也往往是以混凝土的强度(主要是抗压强度)来作为控制喷射混凝土支护质量的主要指标。喷射混凝土的强 The quality of shotcrete support projects depends primarily on the strength of the shotcrete, the adhesion of the shotcrete and the rock layer, and the thickness of the shotcrete. Therefore, the quality control of these factors is very important. First, the control of shotcrete strength Strength is a reflection of the overall quality of shotcrete support indicators, the actual construction is often based on the strength of concrete (mainly the compressive strength) as the main indicator to control the quality of shotcrete support. Strong shotcrete
