The invention relates to technical field of intelligent monitoring of gravel pile machines, in particular to a method for analyzing an effective reverse inserting time of a gravel pile machine. The method for analyzing the effective reverse inserting time of the gravel pile machine comprises the following steps that a curve s1 of the pile sinking depth of the gravel pile machine changing with timeis obtained; a curve s2 of a pile sinking current of the gravel pile machine changing with the time is obtained; and the effective reverse inserting time of the gravel pile machine is obtained according to the curve s1 of the pile sinking depth changing with the time and the curve s2 of the pile sinking current changing with the time. According to the method for analyzing the effective reverse inserting time of the gravel pile machine, by analyzing the construction process of the gravel pile machine, the effective reverse inserting time is comprehensively determined by combining the pile sinking depth with the pile sinking current, the method is simple, and the precision is high. The method for analyzing the effective reverse inserting time of the gravel pile machine completely depends ona digital technology, detection can be implemented in the construction process, the accurate and effective reverse inserting time is quickly obtained, ''sampling control verified after the fact'' isnot necessary, and the construction can be timely fed back and effective correction is performed. The disadvantage of large errors of traditional manual record and lack of standardization caused by human behaviors in the construction operation process can be further avoided.
