The invention discloses a field fast calibration method for the reinforcing-steel-bar semi-grouting-sleeve standard grouting amount. A device comprises an industrial endoscope, an injector, a water injection flexible pipe, a measuring cylinder, a size scale packaging tape and a rubber plug; water is injected into the inside of a sleeve detection sample through an injection device, and the volume V from the bottom of a slurry outlet to the bottom of the sleeve detection sample is detected; the volume of a detection reinforcing-steel-bar sample is measured through the measuring cylinder, thevolume V of an effective insertion section of a connection reinforcing steel bar is obtained, and the sleeve-detection-sample inside standard grouting amount V<0> is obtained by subtracting V from V. By means of the field fast calibration method for the reinforcing-steel-bar semi-grouting-sleeve standard grouting amount, the standard grouting amount of a semi-grouting sleeve can be fast and conveniently calibrated on the field, and the calibration accuracy is high.
