Abstract

An immersed tunnel flexible joint belongs to the field of civil engineering. The joint is divided into an overwater splicing portion and an underwater splicing portion according to a basic form of the flexible immersed tunnel joint. The overwater splicing portion fixes two ends of a GINA water stop belt between a rigid steel ring and a tunnel box body, and an omega-shaped rubber water stop belt is arranged on the inner side and the outer side respectively. The underwater splicing portion fixes the GINA water stop belt at one end of the rigid steel ring, the other end of the rigid steel ring finishes water stop by pulling water pressure, and an omega-shaped rubber water stop belt is arranged in the box body. The immersed tunnel flexible joint has substantive distinguishing features and remarkable improvement and is reasonable in structure and clear in stress. The underwater splicing portion is convenient to construct, and the joint is flexible and has the functions of water resistance and shock resistance and the like under the condition of large deformation.

Description

technical field [0001] The invention belongs to the technical field of civil engineering, in particular to a structural design method for a flexible joint of an immersed tube tunnel. Background technique [0002] The pipe section joint of the immersed tube tunnel is an important part of the immersed tube project. Its joints should have the following functions and requirements: first, water tightness, which requires no water seepage and leakage during the construction and operation of the immersed tube tunnel; second, the joints It should have the ability to resist various actions, including various loads and forced deformation, such as earthquake, temperature and foundation deformation; the third is that the structure of the joint should meet the requirements of clear force, convenient construction and guarantee of construction quality. . [0003] Since the 1960s, the Netherlands and other countries have used GINA waterstops to construct joints by hydraulic pressure bonding...
