Abstract

The invention relates to the technical field of shaft mechanical tunneling and discloses a shaft mechanical tunneling construction method. The shaft mechanical tunneling construction method comprisesthe steps of construction preparation, working pit pre-digging, open caisson blade foot ring and vertical shaft locking opening manufacturing, auxiliary equipment installation, initial lifting and tunneling machine hoisting, open caisson wall lubricant grouting, tunneling excavation, slag discharging, open caisson sinking and heightening, open caisson bottom sealing drainage and open caisson wallrear lubricant replacement. The construction safety of the underground large-diameter shaft can be improved, and the construction efficiency and the mechanization degree are improved.

Description

technical field [0001] The invention relates to the technical field of shaft mechanical excavation, in particular to a shaft mechanical excavation construction method. Background technique [0002] In recent years, with the shortage of urban land resources and the upgrading of planning concepts, the field of urban underground space has developed rapidly. In urban underground space engineering, the development of horizontal construction equipment such as shield tunneling and TBM has been relatively mature. The traditional construction method of digging has extensive production methods, low work efficiency, and great potential safety hazards for construction personnel. It is urgent to develop a brand-new shaft mechanical construction method to realize the purpose of fast construction without going into the well during the construction of underground shafts. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention prop...
