Example Embodiment

[0032] Example 1:

[0033] See Figure 1-5 In this embodiment, taking the reinforced concrete immersed tube tunnel as an example, the reusable assembled end seal structure for the immersed tube tunnel is described in detail, and the section layout of the involved pipe section 1 is a porous layout.

[0034] In the first embodiment, the end seal structure is the same as the common steel beam / concrete hybrid structure end seal door, and several vertical supporting main beams 2 need to be provided as the frame structure of the end seal door. Among them, a number of main beam corbel embedded parts 4 are embedded on the inner wall of the proximal end surface of the pipe section 1. The main beam corbel embedded part 4 is bolted to the main beam corbel 3 as a corbel structure for fixing and supporting the main beam 2. The inner sides of the two ends of the supporting main beam 2 and the main beam corbel 3 are spaced by adjusting blocks 14 and bolted by longitudinal adjusting bolts 9. In...

Example Embodiment

[0043] Example 2:

[0044] See attached Image 6 The basic arrangement of the end seal structure described in this embodiment is roughly the same as that of Embodiment 1. The difference is that the outer side supporting edge seal member 6 and the edge seal member embedded part 7 are not selected as the supporting structure of the edge seal steel plate 13, but a cement step 12 is integrally cast on the inner wall of the pipe section 1. The cement step 12 is the step Edge seal steel plate 13 embedded on the surface. The adoption of this structure reduces the welding steps during installation of the side seal steel plate 13 and further shortens the construction period.

Example Embodiment

[0045] Example 3:

[0046] See attached Figure 7 The difference between the end seal structure described in this embodiment and Embodiment 1 is that the main support beam 2 is not only arranged at the sub-joint of the package door panel 5, but also encrypted in the middle of the package door panel 5. A main supporting beam 2 is provided at the joint of the door panel 5, and a vertical supporting main beam 2 is also provided on the pipe section 1 relative to the middle part of the encapsulating door panel 5. Correspondingly, a spacer strip 11 is added on the inner side of the package door panel 5. The spacer rubber strip 11 is arranged in the annular sealing rubber strip 10, and its two ends are connected with the sealing rubber strip 10 and separated. After the packaging door panel 5 is installed, the spacer rubber strip 11 is located between the packaging door panel 5 and the installation elevation of the supporting main beam 2.

[0047] Combined with the above device structure...

Abstract

The invention relates to the field of construction engineering, in particular to a reusable fabricated end seal structure for an immersed tube tunnel. The end seal structure is mainly composed by combining at least one package door panel, support girders of the package door panel and an outer edge seal support component, wherein a plurality of support girders are sequentially arranged along the transverse section of a pipe and respectively provided with a vertical mounting surface; the outer edge seal support component is provided with an edge seal surface continuously arranged along the inner wall of the pipe; the edge seal surface and the vertical mounting surface of each sequentially-arranged support girder are located in the same plane and combined to form a mounting surface of the package door panel; a plurality of openings are formed between the vertical mounting surface and the edge seal surface; and at least one annular seal rubber strip is arranged on the package door panel, and the package door panel is bolted and fixed on the mounting surface, wherein the seal rubber strip is located and compressed between the package door panel and the mounting surface. The reusable fabricated end seal structure for the immersed tube tunnel has the advantages of greatly improving the construction efficiency and fulfilling the standardized construction.

Description

technical field [0001] The invention relates to technical means for tunnel construction in the field of construction engineering, in particular to a reusable assembled end seal structure for immersed tube tunnels. Background technique [0002] There are many construction methods and corresponding structural forms for underwater tunnels. In recent decades, there are mainly tunnels built by immersed tube method, shield tunneling method and mine method. Among them, immersed tube method is the abbreviation of prefabricated pipe section submerged method. It is a construction method for building tunnels under water. As a reliable construction method for tunnels crossing rivers and seas, the immersed tube method is attracting more and more attention. The construction sequence of the immersed tube method is to first make the tunnel pipe section (using steel plate and concrete or reinforced concrete), and then seal the two ends of the pipe section with temporary sealing walls, then ...
