湿喷混凝土是借助湿喷泵,利用压缩空气,将按一定比例配合的混凝土,通过管道输送并以高速喷射到受喷的岩面、构筑物及建筑物上凝结硬化而成的一种混凝土。除具备普通湿喷混凝土的一切优点外,还可以降低混凝土的回弹率,节省建筑材料,节省投资,提高经济效益适用于输水隧道、地铁隧道、铁路隧道人防工程、军用地下库房建设等工程内壁严重破碎的无钢筋支护,以及推广应用到上述工程的有钢筋混凝土内衬。
Wet-sprayed concrete is a kind of concrete which is formed by condensation and hardening on wet rockets, compressed air, concrete which is matched with a certain proportion, conveyed through pipes and sprayed to sprayed rock face at high speed, structures and buildings. In addition to all the advantages of ordinary wet shotcrete, but also can reduce the rebound rate of concrete, save construction materials, save investment and improve economic efficiency. Suitable for water tunnels, subway tunnels, railway tunnel civil air defense projects, construction of military underground warehouse and other projects Severe broken wall without reinforcement support, and promote the use of the above projects have reinforced concrete lining.
