Bidirectional spraying device for road and bridge construction surface

The utility model relates to the technical field of road and bridge construction. The utility model relates to a spraying device, in particular to a road bridge construction surface two-way spraying device. The utility model has the following beneficial effects; in order to solve the problems that in the prior art, when a novel road and bridge construction surface two-way spraying device conductsspraying, single-face spraying is often conducted; the surface facing the outside of the bridge is particularly inconvenient to spray; even high degree of risk, the spraying is not uniform; the efficiency is low, and particularly, the problem that later maintenance of the steel bridge is very inconvenient is solved; a moving mechanism and a bidirectional spraying mechanism are designed; during use, the second outer shell is turned over firstly; horizontal state, and then the two-way spraying mechanism is moved through the linear guide rail, the spraying position is determined, the second outershell is overturned downw
