Abstract

The invention discloses a seafloor vacuum pipeline traffic system and a pushing type laying method thereof. The system comprises piers built on a seafloor, a pipeline is erected on the piers, the rearend of the pipeline is cooperatively connected with a pushing device and a welding platform, and welded pipelines are pushed to be extended forwards and laid section by section through the pushing device when construction is conducted; the middle of the seafloor vacuum pipeline is provided with a relay pushing station, the pipeline penetrates through the relay pushing station, the relay pushing station is arranged in an artificial island tower, and the front end of the first section pipeline is provided with a positioning guiding diving instrument; the method comprises the steps that a sealing plug is used for sealing a first section pipeline head to be placed into a pushing platform, the pipeline is tightly clamped by a pushing pipe clamp, and another section pipeline is welded to the welding platform; a pushing rod is started, and the pushing pipe clamp and the pipeline enter the sea and are moved forwards constantly until the shore at the other end of the sea is reached. The systemhas the advantages that it is ensured that there exists no bending in the laying process of the pipeline, the system is rapid, efficient and safe, and the engineering cost is low.

Description

technical field

[0001] The invention belongs to the technical field of vacuum pipeline transportation and marine engineering, and in particular relates to a submarine vacuum pipeline transportation system and a push-push laying method thereof. Background technique

[0002] In addition to being affected by air resistance, the future development of aircraft and automobiles will be restricted due to high energy consumption and large carbon emissions. Both high-speed railways and maglev trains are restricted by air resistance, aerodynamic noise, aerodynamic vibration, etc., and cannot further increase their speed. The vacuum tube high-speed transportation will overcome the above-mentioned shortcomings, and it is a transportation mode that can reach ultra-high speed, has low energy consumption, and has little environmental impact. It is expected to fundamentally solve various difficulties faced by human transportation. Vacuum pipeline transportation consists of pipelines, magne...

Embodiment Construction

[0039] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0040] Such as figure 1 As shown, a submarine vacuum pipeline transportation system includes a pipe pier 2 built on the seabed, a pipe 1 is erected on the pipe pier 2, and the rear end of the pipe 1 located on the coast is connected with a pusher 4 and a welding platform 5. During construction, the welded pipeline 1 is pushed joint by joint by the pusher 4 and laid forward along the designed line direction; the middle part of the submarine vacuum pipeline is provided with a relay push station 6, and the pipeline 1 passes through the relay push station 6. The front end of the first section of the pipeline 1 is provided with a positioning and guiding submersible 3, through which the positioning and guiding submersible 3 ensures that the pipeline 1 accurately enters the erection position of the upper part of the pipe pier 2 that is pre-selected and fixed on the seabed. ...
