Ready-mixed wet spraying reinforced sprayed concrete and construction method thereof

The invention relates to a ready-mixed wet spraying reinforced sprayed concrete, which comprises the following components by weight: 30-32 parts of cement; 31.5- 34.5 parts of sand; 38-40.2 parts of fine stone; 0.1-0.2 part of wood fiber; 0.1-0.2 part of cellulose ether; 14.2-16.4 parts of water. The construction method of the ready-mixed wet spraying reinforced sprayed concrete is as follows: 1)a mixing station prepares ready-mixed concrete, and the raw materials are put into a running mixer for mixing, and the mixing time is 1-2 min, the slump of the mixture is controlled to be 100+-20 mm,the initial setting time is 3+-0.5h, and the final setting time is 5+-0.5h; 2) the concrete is transported by a concrete mixer transport truck; 3) during construction at the construction site, beforethe concrete mixer transport truck unloads at the construction site, the rotating tank body is speeded up for 1-2min, then the concrete mixture is unloaded into a pressure drop pump through an unloading hopper, the pressure dro
