The stabilization of the duration borehole wall；After the completion of lining cutting, vertical shaft lining cutting double-walled section is substantially " work " word structure, and the either runtime still drains
Turn(a)round, bears interior external pressure stress condition and is not less than single wall formula vertical shaft.
3) improve construction transportation condition.For conventional vertical shaft generally using buy securities with all one's capital scaffold or slding form operation, shaft height is larger
When, formwork erection and demoulding condition are poor, and after setting the shaft structure marked time, completed mark time of lower shaft can be used as top
The construction channel of vertical shaft formwork erection and demoulding, construction transportation condition are also greatly improved.
4) overall investment increases little.Although it is big to add vertical shaft part double-walled section excavation hole diameter after marking time, due to vertical shaft
It excavates and is generally rock excavation, cubic meter of stone comprehensive utilization benefit is high, and overall investment increases little.
