由于湿式喷射混凝土工艺还存在着许多有待解决的问题,湿式喷射机的研制也处在探索阶段,因此,目前国内仍以干式喷射机为主进行施工。而采用国内现有的混凝土喷射机进行施工,机旁和喷头处都存在着大量飞扬的粉尘,严重地危害工人的身体健康,也就严重地威胁着喷射混凝土这一新技术的生存和发展。因此,减少或消除喷射混凝土施工中产生的粉尘,已经成为急待解决的重要课题。机旁的粉尘,主要是干燥的水泥颗粒随 Due to the wet shotcrete technology there are still many problems to be solved, the development of wet jet is also in the exploration stage, so the current domestic jet is still mainly dry construction. The use of the existing concrete jets in China to carry out construction, there are a large number of aircraft near the jet and the flying dust, seriously endangering the health of workers, it is also a serious threat to the survival and development of this new technology shotcrete. Therefore, reducing or eliminating the dust generated in the construction of shotcrete has become an urgent issue to be solved. Machine next to the dust, mainly dry cement particles with
