Description
technical field
[0001] The invention relates to the technical field of shaft excavation, in particular to a multi-cutter large-section shaft excavation device. Background technique
[0002] At present, shafts are generally excavated artificially or semi-mechanized, or conventional drilling equipment is used for construction. The two methods meet the construction needs of most shaft projects to a certain extent. With the development of the depth direction, the disadvantages of manual semi-mechanized excavation methods in terms of safety and efficiency have become more and more prominent, seriously affecting the progress of the project; while conventional drilling equipment is mainly suitable for shaft construction with medium or small sections, and cannot be directly used for large Cross-section shaft engineering, and a large amount of muck generated during the excavation of large-section shafts, it is necessary to remove the dregs generated during the excavation process in a...
