Problems solved by technology

[0006] The purpose of the present invention is to solve the problems of the inability to seal and water-stop between two relatively movable components in the prior art, and the poor water-stop effect and short service life when a single water-stop device is used, and provide A composite water-stop system when moving and its use method. The water-stop system includes an external water-stop device and an internal water-stop device arranged on two mutually movable components. The water stop device plays the role of backup and composite water stop. When the external water stop device leaks or is damaged, the internal water stop device will play a role to further realize the water stop function without affecting the construction or use, and achieve a composite water stop Effect

Embodiment 1

[0055] Such as figure 2 and image 3 As shown, the mobile composite water-stop system includes a first member 7 and a second member 8 that can move relatively, a joint cavity is formed between them, and an external water-stop device 9 that makes the joint cavity relatively sealed is installed on the two components. , the external water-stop device 9 includes a flexible water-stop belt connected to the first member 7 and the second member 8 respectively, and the extension length of the flexible water-stop belt corresponds to the relative movement length of the two members, and the combined cavity An internal water stop device 10 is also installed in the cavity.

[0056] A joint cavity is formed between two mutually movable components. In order to achieve the purpose of water-tight sealing, an external water-stop device is installed on the two components so that the joint cavity on one side of the external water-stop device is connected to the other side of the external water-...

Embodiment 2

[0074] Such as Figure 4 and Figure 5 As shown, this embodiment is basically the same as Embodiment 1, the difference is:

[0075] The flexible waterstop is installed at the ends of the first component 7 and the second component 8, and the flexible waterstop is installed at the ends of the first component 7 and the second component 8, which can facilitate the installation of the external waterstop device 9, At the same time, when the two components move relative to each other, the external water-stop device 9 interferes with the components, increasing the moving range and distance of the two components, and meeting more application occasions.

[0076] When the space cavity formed by the combination of the first member 7 and the second member 8 is relatively narrow, the flexible waterstop is installed at the end of the member, which is convenient for installation, and at the same time ensures that the relative movement between the two members can be relatively long. No inter...

Embodiment 3

[0078] In this embodiment, the mobile composite water-stop system is arranged in the occasion of relative movement between the final joint and the pushing girder.

[0079] Such as Figure 6 and Figure 7 As shown, the mobile composite waterstop system includes a final joint 1 and a pushing beam 4, a joint cavity is formed between the outer wall of the pushing beam 4 and the final joint 1, and the final joint 1 and the pushing beam The end of 4 is equipped with an external water-stop device 9 that makes the joint chamber relatively sealed. The external water-stop device 9 includes a flexible water-stop connected to the final joint 1 and the pushing girder 4. The extension of the flexible water-stop The length corresponds to the length of pushing the trabecular movement, and an internal water stop device 10 is also installed in the cavity of the combined cavity.

[0080]A joint cavity is formed between two mutually movable components. In order to achieve the purpose of water-t...

Abstract

The invention relates to the technical field of immersed tunnels, in particular to a mobile composite water stopping system and a using method thereof. The mobile composite water stopping system comprises a first component and a second component which move mutually, a combing cavity is formed between the first component and the second component, the two components are provided with an exterior water stopping device enabling the combining cavity to be relatively sealed, the exterior water stopping device comprises flexible water stopping belts which are connected with the first component and the second component, and the extending length of the flexible water stopping belts corresponds to the relatively-moving length of the two components; an interior water stopping device is further installed in a cavity of the combining cavity, the exterior water stopping device of the water stopping system has the main water stopping effect, and the interior water stopping device has the standby andcomposite water stopping effect; and when the exterior water stopping device has leakage or damage, the interior water stopping device plays a role, the water stopping function is further achieved, influences on construction or use are avoided, the composite water stopping effect is achieved, and the dual water stopping aim and effect are achieved.

Description

technical field [0001] The invention relates to the technical field of immersed tube tunnels, in particular to a mobile composite water stop system and its application method. Background technique [0002] Immersed tube method tunnel construction is to float and transport the prefabricated tunnel caissons in semi-submerged barge or dry dock to the predetermined position for sinking and docking. In order to make the last pipe section sink smoothly, it is necessary to leave a space longer than this pipe section. , the butted pipe section placed in the remaining distance space is regarded as the final joint. The final joint of the immersed tube tunnel is the key to the construction of the immersed tube tunnel, especially in the construction of the ultra-long immersed tube tunnel in the open sea, the construction site operation conditions are difficult, and it faces complex marine environmental conditions and meteorological conditions such as waves and currents. [0003] The st...
