Vertical shaft tunneling machine suitable for underwater tunneling

Abstract

The invention discloses a vertical shaft tunneling machine suitable for underwater tunneling. The vertical shaft tunneling machine comprises a cutterhead used for digging a soil layer, and further comprises a slurry inlet system used for conveying high-pressure muddy water to the cutterhead, and a slurry outlet system connected with the cutterhead and used for enabling the high-pressure muddy water entering the cutterhead and carrying muck to flow out of the cutterhead. The vertical shaft tunneling machine suitable for underwater tunneling can adapt to high water pressure in the tunneling process, the high-pressure muddy water can be conveyed to the cutterhead through the slurry inlet system in the tunneling process so that the muck accumulated in the cutterhead can be conveniently washed away; and then the high-pressure muddy water carrying the muck can flow out of the cutterhead through the slurry outlet system, therefore the earlier stage muck treatment procedure can be reduced, muck clearing after shutdown is not needed, one-time forming of a vertical shaft can be facilitated through the arrangement mode, and therefore the working efficiency can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a shaft boring machine suitable for underwater excavation. Background technique [0002] At present, with the urgent need of underground space engineering construction in our country, various shaft boring machines are widely used. In the prior art, shaft construction methods are mainly divided into two categories, one is the common construction method for surface soil section and bedrock section, and the other is special construction method, wherein the special construction method is generally applicable to the situation with large amount of groundwater. However, when a special construction method is used for shaft construction, additional treatment of the soil layer is often required, and the one-time forming of the shaft cannot be completed, which will reduce the working efficiency of the roadheader. [0003] Therefore, how to avoid the inefficiency of work due t...
