Description

Technical Field

[0001] This invention relates to the field of caisson construction technology, and in particular to a bottom-shaft spiral rapid caisson device. Background Technology

[0002] Existing caisson construction methods mainly include traditional caissons, the newly developed mechanically pressurized caissons, and vertical shield tunneling machines. Traditional caissons require dewatering and dry excavation followed by prefabrication of tunnel segments on the ground, resulting in low construction efficiency and high construction risks. Vertical shield tunneling technology is under development, and mechanically pressurized caissons have already begun to be used. Their common feature is the use of assembled prefabricated tunnel segments, leading to high construction efficiency. However, vertical shield tunneling machines require a central cutterhead, while pressurized caissons use a suction head for excavation, combining excavation and prefabrication. Therefore, a bottom-shaft spiral-type rapid caisson construction device is needed to improve the efficiency of caisson construction. Summary of the Invention
