Embodiment Construction

[0051] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0052] The invention proposes an immersed tube tunnel.

[0053] Such as figure 1 As shown, in an embodiment of an immersed tube tunnel proposed by the present invention, the immersed tube tunnel includes a cylinder body, that is, the immersed tube tunnel is formed by butting ends of a plurality of cylinder bodies, and the shape of the cylinder body is cylindrical The cylinder body includes a cylinder wall 100, a first rib 110, a second rib 120, a third rib 130, a fourth rib 140, and a fifth rib 150; both ends of the first rib 110 are connected to the cylinder The inner wall of the wall 100 and the central axis of the cylinder are located on the plane where the first rib 110 is located, that is, the first rib 110 is coplanar with the longitudinal section of the cylinder, that is, the first rib 110 divides the cylinde...

Abstract

The invention discloses an immersed tube tunnel and a construction method. The immersed tube tunnel is formed by connecting a plurality of cylinders end to end in a butt joint mode, wherein each cylinder is cylindrical and comprises a cylinder wall, a first rib plate, a second rib plate, a third rib plate, a fourth rib plate and a fifth rib plate; the two ends of the first rib plate are connectedto the inner wall of the cylinder wall; and the central axis of the cylinder is positioned on the plane where the first rib plate is positioned. The cross section of each cylinder of the immersed tubetunnel is round, compared with a traditional immersed tube with a rectangular cross section, the thickness of the cylinder wall of each cylinder can be reduced as much as possible while the pressurebearing capacity of the cylinder is guaranteed, the production cost, namely the installation cost, of the immersed tube tunnel is reduced, and the construction period is shortened.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to an immersed tube tunnel and a construction method. Background technique [0002] At present, there are two mainstream methods for the construction of underwater tunnels. One is to use underground excavation like traditional subway construction, that is, to use shield machines to dig channels in the soil layer below the bottom of the water. The construction requirements are higher, because the depth of the soil layer under the water bottom is lower than that of land excavation, the early exploration is time-consuming and laborious, and the later excavation and construction efficiency are also slower than that of constructing subways on land, and the cost is huge. [0003] Another way is to adopt the construction method of immersed tube tunnel. Immersed tube tunnel refers to prefabricating immersed tubes in the dock, then transporting the fabricated immersed tubes ...
