摘要
通过对干式混凝土喷射机干混合物料不能充分水化的分析，阐述了采用专用高压变量水泵在喷头处供水的必要性及实施办法，从而达到降低粉尘浓度和回弹率、提高混凝土强度的目的。
Based on the analysis of the problem that the dry mixture was unable to be wetted thoroughly for a dry concrete-sprayer, this paper proposed the necessarity and procedures that a special high-pressure rate-variable water pump was applied to supply water at the spraying jet. In this way less dust and rebound, higher roughness can be expected.
