The invention discloses a rotary excavating drilling bucket pushing type deslagging noise reduction construction method, belongs to the technical field of rotary excavating drilling buckets, and aims to solve the problems that when a rotary excavating drill encounters the condition that deslagging is difficult, a rotary excavating machinist usually operates a drilling bucket to rotate forwards and backwards alternately to impact and throw soil, or drilling slag in the drilling bucket is shaken out through an emergency brake measure in the rotating process, the whole deslagging process generates large noise, and the deslagging effect is poor. The noise of the surrounding environment severely exceeds the standard. The pressure-bearing disc on the upper portion of the drilling bucket is pushed downwards through the drilling machine power head, the pressure-bearing disc pushes the slag discharging plate arranged in the drilling bucket to move downwards through the dowel bar, and therefore slag adhering to the inner wall of the drilling bucket is completely pushed out; the pushing type drilling bucket is adopted for deslagging, deslagging can be completed only by lifting the drilling bucket to make contact with a power pressure plate of the rotary drilling machine to generate continuous pushing force, noise pollution in the deslagging process is greatly reduced, and the noise pollution is greatly reduced especially in a site with strict noise control. And the construction period delay loss caused by shutdown due to complaint caused by overlarge noise is effectively avoided.
