Abstract

The invention discloses a construction method for shield tunneling through the wind shaft. The construction sequence in the prior art of shield tunneling first and then the construction of the main structure of the wind tower is adjusted to construct part of the main structure of the wind tower first and then shield tunneling. The construction of the wind tower will not be affected by the progress of the shield tunneling, which can effectively shorten the construction period and ensure the smooth progress of the later construction, and it is also very reliable and safe in structure.

Description

technical field [0001] The invention relates to a construction method for shield tunneling through an air shaft, belonging to the field of underground engineering. Background technique [0002] With the development of my country's economic construction, in order to meet the needs of urban traffic, a large number of river crossing passages and submarine tunnels have been built one after another. Due to the safety of excavation, the whole process of shield tunneling can realize automatic operation, such as fast excavation, advancement, excavation, and assembled lining. The characteristics of low labor intensity, no impact on ground transportation and facilities, and no impact on underground pipelines and other facilities are more and more adopted by large-section long-distance tunnel projects. [0003] During construction, after the shield machine has excavated the tunnel to a certain amount, the tool wear needs to be repaired and replaced. At the same time, in order to meet th...
