Abstract

The invention discloses a water spraying device for fine aggregate concrete protective layer pouring maintenance. The water spraying device comprises a horizontally-arranged base, wherein moving crawler belts are arranged at the two ends of the base, a water tank is arranged on the side wall of the upper side of the base, a communicating hole communicating with the outside is formed in the upper end of the water tank, a tank cover matched with the communicating hole is arranged at the upper end of the water tank, a mixing mechanism is arranged inside the water tank, a first spraying mechanismis arranged at one end of the water tank, a second spraying mechanism is arranged at the other end of the water tank, and the first spraying mechanism and the second spraying mechanism are both arranged close to the base. According to the water spraying device, through two different water spraying modes, the use requirements of users are met conveniently.

Description

technical field [0001] The invention relates to the technical field of building maintenance, in particular to a water spray device for pouring and maintenance of a fine stone concrete protective layer. Background technique [0002] Fine stone concrete generally refers to concrete whose maximum particle size of coarse aggregate is not greater than 15mm. Pozzolanic cement shall not be used in fine stone concrete; medium-coarse sand with a particle size of 0.3-0.5mm is used for sand, and the mud content of coarse aggregate shall not exceed 1%; the mud content of fine aggregate should not be greater than 2%; the water should be tap water or potable natural water; the concrete strength should not be lower than C20, the amount of cement per cubic meter should not be less than 330kg, and the water-cement ratio should not be greater than 0.55; the sand content should be 35% to 40%; the lime-sand ratio should be 1:2 to 1:2.5. Self-compacting concrete is also a kind of fine stone conc...
