Abstract: A method for determining a consistency coefficient of a power-law cement grout includes: determining a water-cement ratio of the power-law cement grout; according to engineering practice requirements, determining a time required to determine the consistency coefficient of the power-law cement grout; and obtaining the consistency coefficient of the power-law cement grout. The method is accurate and reliable, requires less calculation, etc.; and has very high practical value and popularization value in environmental protection and ecological restoration.

Abstract: A glue rewarming device includes a glue pipe, a main body, a plurality of temperature sensors, a timer, and a control terminal. Each glue pipe is configured to receive glue. The main body defines the grooves spaced apart from each other. Each groove is configured to receive one glue pipe. Each temperature sensor is in one groove and on an inner wall of the one groove. The temperature sensor is configured to sense a temperature of the glue in the glue pipe inserted into the corresponding groove. The timer is configured to record a time point when the glue pipe is placed in one groove and a time length from the time point when the glue pipe is placed in one groove to the time when the glue in the glue pipe reaches a target temperature. The control terminal is electrically connected to the timer and the temperature sensors.
