Telescopic T-shaped spraying protection tool for maintaining constructional engineering concretes and moisturizing brick walls

The invention discloses a telescopic T-shaped spraying protection tool for maintaining constructional engineering concretes and moisturizing brick walls. The tool comprises a transverse spraying pipe 12, a handle 13 and a water receiving flexible pipe 11, wherein the transverse spraying pipe 12 comprises a main pipe 1 and a secondary pipe 2; the main pipe 1 and the secondary pipe 2 are fixedly connected through a short thread joint 3; holes 4 are formed in the main pipe 1 and the secondary pipe 2; a pipe plug 5 is mounted at the outer end of the secondary pipe 2; a straight three-way 6 is mounted in the main pipe 1; and the other end of the straight three-way 6 is connected with the handle 13. Compared with a traditional flexible pipe spraying mode, the tool can save the water consumption of 50% under the condition of equal spraying area, and can completely and evenly spray water; in the construction work, the tool can adjust the magnitude of the water flow at any time, and can open and close a water source at any time without causing the water waste; constructed floors have no obvious ponding phenomenon; and the construction site is clear and clean to achieve the standards of safe and civilized construction.
