Embodiment 1

[0040] like Figure 1-5As shown, a sandwich immersed pipe joint includes a ring-shaped steel structure shell composed of a bottom plate 1, a top plate 2, and a side wall 3 connected between the bottom plate 1 and the top plate 2, and a number of longitudinal partitions are arranged in the shell. Plates 6 and transverse partitions 7, all of the transverse partitions 7 and longitudinal partitions 6 separate the housing into several mutually independent compartment units 5; each of the compartment units 5 is also provided with several Stiffening panels, each of the compartment units 5 is filled with concrete 12 .

[0041] like Figure 4-5 As shown, each of the longitudinal partitions 6 described above is arranged along the longitudinal direction of the steel structure shell, and each of the transverse partition plates 7 is arranged along the lateral direction of the steel structure shell. All the longitudinal partitions 6 and transverse partitions 7 are welded to the bottom pla...

Embodiment 2

[0046] The present invention also provides a method for producing the above-mentioned sandwich immersed pipe joint, comprising the following steps:

[0047] Step 1: Pretreatment of the steel plate. According to the prefabricated shape of the immersed pipe joint, each part of the immersed pipe joint is formed, including the steel plates required for the pretreatment of the top plate 2, the bottom plate 1, and the side wall 3; specifically, it can be based on the size of the design drawings. , Consider the deviation in the processing process, the tolerance required for assembly, the gap and the inversion value, as well as the shrinkage in the process of welding and flame correction. After calculating the precise size, reasonable lofting is carried out. Steel plate pretreatment, cutting and blanking. The plate unit is welded by two-way anti-deformation frame and multi-head portal automatic welding machine in the production, which can effectively control the welding deformation, r...

Abstract

The invention discloses a sandwich sinking pipe connector and a production method thereof. The sinking pipe connector comprises an annular steel structure shell composed of a bottom plate, a top plateand side walls connected between the bottom plate and the top plate, the shell is internally provided with a plurality of longitudinal partition plates and transverse partition plates, and all the transverse partition plates and longitudinal partition plates partition the shell into a plurality of mutually-independent compartment units. Each compartment unit is further internally provided with aplurality of stiffening plates and filled with concrete. According to the sandwich sinking pipe connector, in the adopted steel structure shell, the stiffening plates can be in rigid connection with the compartment units in longitudinal and transverse directions, and when each compartment unit is cast again, it is ensured that a shell body and the filled concrete deform jointly, so that the situation that slippage occurs between the bottom plate and the concrete interface, the top plate and the concrete interface as well as the side walls and the concrete interface is prevented, and thus the rigidity and the strength of the sinking pipe connector are ensured so as to adapt to the seabed sinking pipe requirement; and forming is achieved at a time, subsequent maintenance can be omitted, theusing requirement for 120-year durability can be met, and stability is good.

Description

technical field [0001] The invention relates to the technical field of immersed tube tunnels, in particular to a sandwich immersed tube joint, a prefabrication method for the sandwich immersed tube joint, and an installation method for the sandwich immersed tube joint. Background technique [0002] Immersed tube tunnel construction is to float and transport the prefabricated tunnel immersed tubes in the semi-submerged barge or dry dock to the predetermined position for sinking and docking. At present, the large submarine immersed tube tunnels built in the world are mainly distributed in the United States, Europe and the United States. In Japan, although several immersed tube tunnels have been built in China, there are no large-scale subsea immersed tube tunnels that have been built yet. There are domestic deep sea or cross-sea immersed tube tunnels that are planned or under construction. The technical and construction period requirements are a severe challenge to the constru...
