Embodiment 1

[0074] This embodiment 1 provides a construction method for the dock door to be floated out of the dock for installation. It should be noted that when implementing this embodiment 1, the dock door 1 should be located at the storage position in the dock. Present embodiment 1 specifically comprises the following steps:

[0075] S1, extracting the accumulated water in the water storage chamber to float the dock door 1;

[0076] In this embodiment 1, the dock door 1 has a water storage cavity, and water can be poured into the water storage cavity to facilitate the sinking of the dock door 1, that is, to make the dock door 1 sit on the bottom by pressing water, and to facilitate storage of the dock door. 1. It is possible to reduce the weight of the dock door 1 by pumping out the accumulated water in the water storage chamber, so as to facilitate the floating of the dock door 1 and facilitate the floating transportation of the dock door 1. In the present embodiment 1, the accumula...

Embodiment 2

[0103] Embodiment 2 is the specific structure of the dock door in Embodiment 1.

[0104] The dock door 1 of the present embodiment 2 includes a steel frame 5; as Figure 16 to Figure 18 As shown, the steel frame 5 is preferably cuboid, and the steel frame 5 is provided with a bottom plate 51, a top plate 52, a first panel 53, a second panel 54, a first side plate 55 and a second side plate 56; the bottom plate 51 and the top plate 52 are opposite Set, the first panel 53 and the second panel 54 are set oppositely, the first side plate 55 and the second side plate 56 are set oppositely, the bottom plate 51, the top plate 52, the first panel 53, the second panel 54, the first side plate 55 and The second side plate 56 together constitutes the steel frame 5; specifically, the bottom plate 51, the top plate 52, the first panel 53, the second panel 54, the first side plate 55 and the second side plate 56 are spliced ​​by several steel plates. The steel frame 5 is provided with an i...

Abstract

The invention belongs to the technical field of immersed tube tunnels, and particularly relates to a construction method for floating transportation undocking installation of a dock gate. The method comprises the dock gate placed in a dock, the dock gate is provided with a water storage cavity, and the method comprises the following steps that S1, accumulated water in the water storage cavity is pumped out, so that the dock gate floats; S2, the dock gate is transported out of the dock in a floating mode; S3, after the dock gate is undocked, the direction of the dock gate is adjusted to enable the dock gate to reach the mounting position; S4, water is poured into the water storage cavity, so that the dock gate presses water to sit at the bottom; and S5, the dock gate is installed. According to the construction method, accumulated water in the water storage cavity of the dock gate is pumped out, so that the weight of the dock gate can be reduced, the dock gate can be conveniently transported out of the dock in a floating mode, after the dock gate is undocked, the position of the dock gate is adjusted, so that the dock gate reaches the mounting position, the position precision of the dock gate after reaching the mounting position can be guaranteed, installation is carried out after the dock gate is set at the bottom, the dock gate in the dock can be conveniently transported out of the dock in a floating mode, the position precision of the dock gate after the dock gate reaches the installation position can be guaranteed, and then the precision of re-installation of the dock gate can be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of immersed tube tunnels, and in particular relates to a construction method for floating and undocking installation of a dock door. Background technique [0002] The underwater tunnel is composed of multiple immersed tubes with huge volume and weight connected to each other. At present, the immersed tube is generally prefabricated in the dry dock. After the prefabrication in the dry dock is completed, the immersed tube is floated out of the dock and installed by storing water in the dock. [0003] Due to the operation of dry dock construction and water storage in the dock during the construction process, the position of the dock door needs to be moved according to the actual situation: when floating and sinking the tube, the dock door needs to be moved to the dock for storage, and the flowing water into the dock; when prefabricating the immersed tube, the dock door needs to be floated out of the dock and i...
