Shaft and shaft station connecting portion and safe and rapid construction method

The invention provides a shaft and shaft station connecting portion and a safe and rapid construction method. The shaft and shaft station connecting portion comprises a first horsehead, a second horsehead and a transition portion, wherein one end of the first horsehead communicates with a shaft; the other end of the first horsehead communicates with a shaft station; the second horsehead is opposite to the first horsehead through the shaft; and the transition portion is located at a position where the shaft station is connected with the first horsehead. The safe and rapid construction method ofthe safe and rapid construction method comprises the steps of digging and constructing the shaft; digging and constructing a first construction section layer; and digging and constructing a second construction section layer. The horseheads of the shaft and shaft station connecting portion oppositely communicate with each other from the two sides of the shaft station through a roadheader by a layered continuous constructi
