Problems solved by technology

However, due to the differences in basic structural forms, scales and working environments, the form of connecting components cannot directly meet the needs of floating tunnels.
[0006] At present, there are also researches and inventions on the connecting components of floating tunnels, but most of them are based on the improvement of the joint form of immersed tube tunnels, and have not been invented for the special movement forms of floating tunnels

Abstract

The invention discloses a suspension tunnel connecting component. The suspension tunnel connecting component comprises a connector head and a connector tail which are in butt joint with a front pipe section and a rear pipe section; the head and the tail of the connector are connected through three stress components, namely a radial stress component for bearing radial load and generated displacement of the suspension tunnel, an axial stress component for bearing axial load and displacement and an annular stress component for bearing annular load and rotation; and the stress components are connected to spherical hinge springs through connecting shafts, so that the shock-absorbing and buffering performance is ensured, and the relative degree of freedom of the head and the tail of the connector is met. Compared with a traditional immersed tube connection tunnel connector, the suspension tunnel connecting component is provided with the components which are stressed in the axial direction, the radial direction and the annular direction, the freedom degree in the six directions is met, and the suspension tunnel connecting component can adapt to vibration and deformation generated by a suspension tunnel in the complex marine environment.

Description

technical field [0001] The invention relates to a floating tunnel connection component. Background technique [0002] The floating tunnel, also known as the Archimedes bridge, is a large-scale cross-water traffic structure that uses buoyancy to support the tunnel's own weight load and traffic load according to the Archimedes principle. It is mainly used to solve the problem of crossing deep waters and wide waters. Its advantage is that technically the floating tunnel is not limited by the span and water depth, and can be built in locations with long spans, deep water levels, and steep bank slopes, and its cost per unit length does not increase with the increase of the span. However, the floating tunnel has not yet formed a systematic and complete theoretical system in the world. It is necessary to break through major core scientific problems such as the structural bearing capacity characteristics of long-span floating tunnels, the stability of structural support systems unde...
