Embodiment 1

[0038] As shown in Figures 1 and 4, a water stop for an immersed tube tunnel is a device used to prevent the water outside the immersed tube from leaking into the immersed tube at the joint between the two immersed tubes of the underwater immersed tube tunnel. It includes an inflatable body 2, a base 1 and a water-stop edge 3 with inflatable elasticity; the inflatable body 2 has a base body 21, a top body 23 and a support body 22 between the base body 21 and the top body 23; the inflatable body The base body 21 of 2 is connected to the base 1; a water-stop edge 3 and two swing control edges 4 are arranged on the top of the top body 23 of the inflatable body 2, and the two swing control edges 4 are symmetrically arranged on the sides of the water-stop edge 3 On both sides; there are grooves 6 between the water stop edge 3 and the swing control edge 4 on both sides.

[0039] Such as Figure 8 , 9 As shown, we use immersed tube one 8 and immersed tube two 9 to represent two adj...

Embodiment 2

[0052] In Embodiment 1, the water-stop edge 3 is integrally formed with the sway control edges 4 on both sides and the inflatable body 2, and the material of the water-stop edge 3 is the same as that of the sway control edges 4 on both sides and the inflatable body 2. In the embodiment, the water-stop edge 3 and the swing control edges 4 on both sides are integrally formed, and the water-stop edge 3 and the swing control edges 4 on both sides form a common matrix 5, and the common matrix 5 and the compression body 2 are of a separate structure. The co-matrix 5 and the inflatable body 2 are bonded together by vulcanization, and the materials of the co-matrix 5 and the inflatable body 2 are different.

[0053] Such as Figure 10 As shown, a waterstop for an immersed tube tunnel is different from Embodiment 1 in that: the waterstop 3 and the two sides of the control edge 4 are combined into a common matrix 5, and the common matrix 5 is vulcanized and glued. It is connected to th...

Abstract

The invention discloses a waterstop belt for an immersed tunnel. The waterstop belt comprises a dilatancy body with a base body and a top body, a base connected with the base body of the dilatancy body, and a waterstop edge arranged on the top of the dilatancy body and having dilatancy elasticity on the top, symmetrically-arranged shaking control sides with dilatancy elasticity are arranged on thetwo sides of the waterstop edge of the top of the top body, and grooves are formed between the waterstop edge and the shaking control sides on the two sides. The waterstop belt has the advantages that the shaking amplitude and the shaking frequency of ends of two adjacent sections of immersed tubes in the water bottom closing process of the immersed tubes can be effectively limited, the linking precision of two sections of immersed tubes is improved, meanwhile, the waterstop belt can adapt to large-displacement staggering of two sections of immersed tubes between the combination portions dueto the strong earthquake, and the service life of the waterstop belt can be prolonged.

Description

technical field [0001] The invention relates to a water stop belt for an immersed tube tunnel, which belongs to the technical field of underground engineering. Background technique [0002] As we all know, earthquakes are extremely destructive. As a lifeline project, underwater immersed tube tunnels are very vulnerable to earthquakes, especially the failure of the water-stop effect will lead to catastrophic consequences. [0003] At present, in the field of immersed tube tunnels, rubber waterstops with large compression capacity are used between the joints of two adjacent immersed tubes to play the role of sealing and water-stopping. The waterstop is in the shape of a whole strip, and its large compression must ensure that the seismic fortification intensity is above Ⅶ, so as to ensure the sealing and watertightness between the joints of the immersed tubes during strong earthquakes; at the same time, it can buffer the impact between the immersed tubes And the function of tr...
