A shaft excavation construction method (shaft excavation construction method) using the shaft excavation equipment 11 having the dual mode slag tapping (which may also be referred to as shaft excavation equipment having the dual mode slag tapping function) is described below, and the shaft excavation construction method includes the steps of:

when the machine works on the waterless ground, the residue soil conveyor 6 transports away the residue soil solids generated by excavation by the milling and excavating head 1; when the underwater working is carried out, the muck slurry suction pipe 8 can suck away muck slurry generated by the digging of the milling and digging head 1. The shovel plate 9 and the conveyor 6 constitute a dry tapping system. The shovel plate 9, the slurry suction pipe 8, the slurry outlet pipe 5 and a slurry pump in the vehicle body 4 form a wet-type slag discharging system. During dry slag discharge, the slag soil needs to be conveyed to the ground by matching with the gantry crane 12 and the grab bucket 15. During wet slag discharging, the slurry is connected and conveyed to a ground mud-water separation station 13 through a slurry outlet pipe 5, and the mud-water separation station separates out slag soil and discharges the slag soil to a slag yard for transportation.

The specific operation of the shaft excavation equipment with the dual mode tapping will be described below.

When the excavation depth of the vertical shaft is shallow, the vertical shaft is generally an anhydrous stratum firstly. When the excavation is carried out to a certain depth, the water-rich stratum can be met.

When the waterless stratum works, the milling and excavating head 1 cuts into a rock mass with a certain depth, and the vertical shaft excavating equipment 11 with the dual-mode slag discharging mode walks and excavates according to a fixed track. Rock slag (namely, solid muck) excavated by the milling and excavating head 1 is shoveled by a shovel plate 9 behind the milling and excavating head 1, and the solid muck is conveyed to a rear conveyor 6 through the rotation of two groups of star-shaped slag poking wheels 901 on the shovel plate 9 and is conveyed to the tail part of the equipment by the conveyor 6 to be discharged or temporarily collected. The grab bucket 15 is then suspended by the gantry crane 12 on the ground, and the grab bucket 15 discharges the debris to the debris field 14 on the ground, as shown in fig. 4.

When the shaft excavation equipment with the dual-mode slag discharging function works in a water-rich stratum, the conveyor 6 stops working, the shaft excavation equipment with the dual-mode slag discharging function can work under half water or below the full water surface, as shown in fig. 5, residual soil mud on the shovel plate 9 is absorbed by a mud pump through the mud suction pipe 8 and then conveyed to the ground mud-water separation station 13 through the mud discharging pipe 5, the separated mud is circulated and returned to the well, and the residual soil is discharged to the slag field 14.
