The invention discloses a through split type while-drilling soil discharging device and cast-in-place pile hole forming equipment, the through split type while-drilling soil discharging device comprises at least two split type slag salvaging barrels and a connecting lock catch, the at least two split type slag salvaging barrels are sequentially spliced to form a circular-ring-shaped slag salvaging barrel body, and the connecting lock catch is connected with the slag salvaging barrel body. Every two adjacent split slag salvaging barrels are detachably connected through a connecting lock catch, and slag filtering holes are formed in the bottom walls of the split slag salvaging barrels. According to the core-penetrating split type while-drilling soil discharging device, a dry operation soil discharging and slag discharging process under the condition that obstacles such as a drill rod or a rope exist in the middle of a drill hole is achieved through the core-penetrating slag salvaging barrel device capable of be
