SPZ—6型湿式混凝土喷射机的研制

喷射混凝土支护是广泛应用于地下矿山、隧道工程及建筑工地的一种新技术。目前国内主要使用干式混凝土喷射机，作业粉尘浓度大、回弹率高，不仅污染了作业环境，而且降低了支护强度，造成物料的浪费。最新研制成功的ＳＰＺ－６型湿式混凝土喷射机具有作业粉尘浓度低、回弹少、喷射混凝土强度高等优点，推广应用的前景广阔。本文详细介绍了该设备的工作原理、结构特点及其使用情况

DEVELOPMENT OF TYPE SPZ-6 WET CONCRETE SPRAYER

The new technology of shotcreting support is widely used in the underground mining,tunnel construction and building construction.At present dry concrete sprayers are mainly used in China so as to have higher dust and more reflectance,not only polluting operating environment but also lowering supporting strength and resulting in waste materials.The shortcomings of dry concrete sprayers are overcomed effectively by recently developed model SPZ-6 wet concrete sprayer which has lower dust,less reflectance and higher shotcreting strength.The prospects of its application and development are broad.This paper presents the principles and structural features of model SPZ-6 wet concrete sprayer in detail.Its application is also in troduced in the paper.
