Cement mortar sprayed wall building formwork technology

The invention relates to a cement mortar sprayed wall building method. The cement mortar sprayed wall building method includes the steps of (1) using 2 cm*4 cm square steel as keels, and welding the square steel to form 60 cm*60 cm boxes which serve as the keels on the inner side and the outer side of a wall, wherein the distance between the keels is the thickness of the wall, and the thickness of the wall is adjusted according to thermotechnical requirements; (2) hanging a steel net 1.5 cm*1.5 cm in mesh specification on the inner side of each keel, hanging a layer of non-woven fabric on the inner side of each steel net, and connecting the non-woven fabric with the steel nets through iron wire binding wires; (3) preparing cement mortar doped with 2% of PP fibers, 2% of triethanolamine and 2% of polypropylene fiber dry powder; (4) pouring the prepared cement mortar into a mortar spraying machine, and spraying the two sides of the keels of the wall, wherein the spraying thickness is 3 cm; (5) leveling the wall
