Problems solved by technology

[0007] The submarine vacuum pipeline engineering test line of more than 5km has a long line mileage, a large amount of engineering, and high cost. If it is only used as a test line for construction and application, it will face idle or abandoned after the test task is completed. result, waste of resources

Embodiment Construction

[0051] The specific content of the present invention will be further explained in detail below in conjunction with the examples.

[0052] Such as Figure 1-Figure 6 As shown, the present embodiment provides a subsea vacuum pipeline test line that can be extended as an application line, including a vacuum pipeline 1 in the land section, a vacuum pipeline 2 in the near-shore subsea buried section, and a vacuum pipeline 3 in the elevated section of the seabed, which are arranged in sequence, and A subsea pipe pier 4 for supporting the vacuum pipeline 3 of the subsea elevated section;

[0053] The vacuum pipeline 2 of the offshore seabed buried section refers to the pipeline between the coastline and the water entry point where the vacuum pipeline buried underground enters the sea from the seabed, and this section belongs to the sea area;

[0054] The end of the vacuum pipeline 3 of the elevated section of the seabed is provided with an inner removal head 5 and an extension joint...

Abstract

The invention discloses a submarine vacuum pipeline test line capable of extending into an application line and an implementation method thereof. The submarine vacuum pipeline test line comprises a land section vacuum pipeline, a near-shore submarine embedded section vacuum pipeline, a submarine elevated section vacuum pipeline and a submarine pipe pier, the land section vacuum pipeline, the near-shore submarine embedded section vacuum pipeline and the submarine elevated section vacuum pipeline sequentially communicate with each other, and the submarine pipe pier is used for supporting the submarine elevated section vacuum pipeline; an inner removal seal head and an extension butt joint are arranged at the terminal end of the submarine elevated section vacuum pipeline; and an air brake cabin is arranged at the head end of the land section vacuum pipeline. The invention further discloses the implementation method of the submarine vacuum pipeline test line. The section of the submarine vacuum pipeline is far smaller than that of a traditional tunnel, and the construction cost is greatly lower than that of a traditional tunnel; and after the test task is completed, the line trend of the cross-sea channel needing to be built is further extended, so that the test line is extended into the application line, the construction cost is saved, the resource utilization rate is improved, and the cross-sea channel engineering construction process is accelerated.

Description

technical field [0001] The invention belongs to the technical field of submarine vacuum pipeline traffic research and development and engineering construction, and in particular relates to a submarine vacuum pipeline test line that can be extended into an application line and an implementation method thereof. Background technique [0002] The existing cross-sea channel projects mainly include three types: cross-sea bridge, undersea tunnel, and immersed tube tunnel. The technologies are relatively mature and have been applied in many projects, such as the Seikan Subsea Tunnel in Japan, the British-French Subsea Tunnel, and the Hong Kong-Zhuhai-Macao Bridge in China. The east and west sections of the sea-crossing bridge and the middle section of the immersed tube tunnel. Sea-crossing bridges and immersed tube tunnels are only suitable for shallow seas. Among them, immersed tube tunnels also require gentle seabed topography and are not suitable for sea areas with large seabed f...
