Abstract

The invention discloses an immersed tube structure suitable for high flow rates and a construction method thereof, belonging to the field of immersed tubes. The invention discloses an immersed tube structure suitable for high flow rates, including an immersed tube body, and inside the immersed tube body A channel for opening to traffic is provided, one side of the immersed tube body is provided with several shrouds along the length direction, the outer side of the shrouds is provided with elastic capsules, each of the shrouds is provided with a A protrusion control device, the protrusion control device props up the elastic capsule body to control the protrusion degree of the elastic capsule body, and the protrusion degree of each shroud can be adjusted individually. According to the flow velocity of the water flow, adjust the protrusion degree of the elastic capsule body through the protrusion control device, so as to change the action surface of the water flow on the elastic capsule body, and change the direction of the water flow passing through the surface of the elastic capsule body, thereby changing the force of the water flow on the immersed tube body The size of the immersed tube can reduce the influence of the water flow on the body of the immersed tube when the water flow velocity is relatively high.

Description

technical field [0001] The invention relates to the field of immersed tubes, in particular to an immersed tube structure suitable for high flow rates and a construction method thereof. Background technique [0002] The immersed tube method is the abbreviation of the prefabricated pipe section immersed method, and it is a construction method for building tunnels under water. The construction sequence is to first make the tunnel pipe section (using steel plate and concrete or reinforced concrete) on the berth or in the dry dock, seal the two ends of the pipe section with a temporary sealing wall, and then slide into the water (or release water in the dock) to make it float in the water , and then dragged to the tunnel design location. After positioning, load the pipe section to make it sink into the pre-dug underwater trench. The pipe sections are lowered section by section, and the adjacent pipe sections are connected by hydraulic crimping. Finally, the sealing wall is rem...
