CONFIRMATION METHOD FOR CONSTRUCTION STATE OF SPRAYED MORTAR

摘要

PROBLEM TO BE SOLVED: To provide a confirmation method for the construction state of sprayed mortar that allows the construction state of sprayed mortar sprayed by a dry spray method to be promptly and easily confirmed.SOLUTION: The confirmation method for the construction state of sprayed mortar sprayed by a dry spray method is provided that comprises: a standard formation step in which a standard mortar of a prescribed thickness is formed by spraying a mixture of powdery materials and liquid materials of prescribed ratios from a spray nozzle; a sprayed ratio calculation step in which the sprayed mortar ratio, representing the ratio of the mass of the standard mortar to the total flow of the powdery materials and liquid materials sprayed from the spray nozzle in the standard mortar formation step, is calculated; and a sprayed amount estimation step in which the estimated mass of sprayed mortar is calculated by multiplying the total mass of the powdery materials and liquid materials sprayed from the spray nozzle when forming the sprayed mortar by the sprayed mortar ratio.
