As shown in fig. 7, another solution to the on-way resistance drop is provided in the present embodiment; the nozzle 206 comprises a main pipe 2066 and a straight pipe 2064, wherein a plurality of through holes 2065 are formed in the straight pipe 2064, and the through holes 2065 have the same interval and are arranged in a straight line; the end of the material guiding pipe 207 is communicated with the main pipe 2066, and the aperture of the through hole 2065 is the smallest at the middle part of the straight pipe 2064 and gradually increases outwards. The purpose is that the velocity of the water repellent spray that is sprayed out through the through holes 2065 at the two ends of the straight tubes 2064 is lower than the velocity of the spray out through the through holes 2065 located in the middle of the straight tubes 2064 due to the loss of on-way resistance along the length direction of the straight tubes 2064; therefore, according to the equation of fluid mechanics continuity, when the size of the through holes 2065 is the same, the flow rate of the waterproof coating ejected from the middle through hole 2065 is greater than the flow rate of the waterproof coating ejected from the through holes 2065 at the ends of the straight tube 2064, which eventually results in the thickness of the waterproof coating in the middle area after spraying being greater than the thickness of the waterproof coating at the two end areas of the straight tube 2064, so that the sprayed thickness is not uniform. In order to solve the problem, in this embodiment, the aperture of the through hole 2065 is the smallest at the middle of the straight tube 2064 and gradually increases outwards, so as to ensure that the flow rate of the waterproof coating ejected from each through hole 2065 is the same, and the spraying thickness is uniform.

The contact area of the support column 101 and the ground is small, so that the situation that the support column 101 is in contact with the ground covers a large area in the spraying process is avoided, the waterproof spraying operation is affected, and the waterproof effect is reduced.
Because the ground supported by the supporting columns 101 has different hardness, when the spray gun 20 performs a spraying operation, the spray gun can repeatedly move on the sliding rails 107, the stress between each supporting column 101 and the ground can be changed in the moving process of the spray gun 20, if one supporting column 101 supports a hard ground and the other supporting column 101 supports a soft ground, when the spray gun 20 moves to the supporting column 101 close to the soft ground, the supporting column 101 at the position can sink, and the sinking depth can continuously increase in the repeated operation of the spray gun 20, and finally, the distance between the spray gun 20 and a spraying target surface is inconsistent, so that the sprayed waterproof coating is not uniform.
