一、工艺原理注浆一一真空工艺原理如图1所示。注浆——真空工艺系采用高流态水泥砂浆混合物泵送入模,再借助真空装置使其脱水密实,获得具有一定强度的凝聚结构。从而达到立即脱模及改善水泥砂浆各项物理——力学性能的目的。本工艺实质上包括注浆和脱水密实两个不同的工艺过程。注浆过程是高流态水泥砂浆在泵送压力 First, the principle of process grouting one by one vacuum process principle shown in Figure 1. Grouting—The vacuum process uses a high-fluid cement mortar mixture pumped into the mold, which is dewatered and densified by a vacuum device to obtain an agglomerated structure with a certain strength. In order to achieve immediate demoulding and improve the physical and mechanical properties of cement mortar. The process essentially includes two different processes of grouting and dewatering. Grouting process is high flow cement mortar at pumping pressure
