Method of constructing a shaft, in particular for mining

摘要

The invention relates to a method of constructing a shaft (41), in particular for mining. According to the invention, it is proposed to float the shaft lining column as preliminary shaft lining tube (9) down to the bottom of a borehole after the borehole extending into the competent ground is made, to place underwater concrete (24) between the preliminary shaft lining tube (9) and the ground (3) when the level (20) of the ballast water (18) rises, to break through the soil after the underwater concrete (24) has set, and to prepare the excavation (29) and the foundation (30) after the draining down below the level of the planned excavation and then to construct the final, pressure-water-tight shaft lining (41) starting from the foundation (30) up to the borehole mouth (6) by a formwork method or behind a steel inliner. <IMAGE>
