| Zusammenfassung: | The underground structure constructing method includes drawing forward the concrete caisson in excellent constructing direction, raised safety and good construction performance; injecting liquid chemical into foundation simply without constructing liquid chemical guiding slot for reinforcing to avoid collapse of the dug surface. During the construction, guide hole is constructed for guiding the caisson in correct direction, PC steel cable or other drawing part is inserted into the guide hole, and liquid chemical for reinforcing foundation is injected in the cross section of the underground structure via the guide hole. |
