AI Technical Summary

Technical Problem

Traditional shield construction is difficult to be applicable to tunnel construction in ultra-deep and ultra-wide water environments, especially when completing the assembly and construction of boring machine equipment in underwater formations.

Method used

A floating island-type platform starting from the water surface assembly of the tunnel boring machine is designed, including the platform deck, ramp, floating body and platform position adjustment driver. The platform deck is floating on the water surface by adjusting the buoyancy of the floating body, realizing the water surface assembly and tunnel boring of the tunnel boring machine.

Benefits of technology

This plan breaks through the limitations of the traditional land environment shield construction method, realizes efficient tunnel excavation construction in ultra-deep water environment, improves construction efficiency and scope of application, and shortens the tunnel construction cycle.

Abstract

The utility model relates to a floating island type platform for water surface assembly launching of a tunnel boring machine. The floating island type platform comprises a platform deck used for assembling the tunnel boring machine, a slope ramp used for collecting and releasing the tunnel boring machine, a floating body used for supporting the platform deck and provided with adjustable buoyancy and a platform position adjusting driver. The floating body floats on a water body, the platform deck is fixed above the floating body, the platform position adjusting driver is fixed on the floating body, the platform position adjusting driver is located in the water body, the slope ramp is of a tubular structure, one end of the slope ramp is connected with the platform deck, and the other end of the slope ramp is located in a soil body. Compared with the prior art, after the tunneling construction task of the current section of the tunnel is completed, the entrance can be closed, the artificial platform can be moved to the entrance position of the next section of the tunnel to open up a new tunneling section, the artificial platform can be reused, the use is more flexible, the operation can be carried out in an ultra-deep water area, and the application range is wider.
