Tide type floating barrel structure suitable for suspension tunnel

Abstract

The invention discloses a tide type floating barrel structure suitable for a suspension tunnel. A floating barrel body structure, a water irrigation and discharging system, a crossing overhauling channel, an auxiliary facility and the like are included. A closed box structure defined by a steel plate shell can be adopted in the floating barrel body structure, the outer portion is in a streamline type, the interior is subjected to structure strengthening through longitudinal and transverse partition plates, and a balance weight bin, an equipment bin, a tide bin and other cabin structures are divided. The water irrigation and discharging system comprises water irrigation and discharging equipment, the water level of the tide bin can be accurately adjusted according to the actual water levelof the sea level, and the purposes of adjusting the dead load of the floating barrel structure and reducing influences of tidal range loads on the suspension tunnel are achieved. The auxiliary facility can comprise a solar power generation device, a bollard, lighting equipment and the like. The tide type floating barrel structure solves the design problems that influences on a floating barrel typesuspension tunnel from the tidal range are high, and floating barrel operation and maintenance are not convenient. Various parts of structures are simple in construction, main materials are concrete,steel and other common materials, the engineering cost is low, and daily operation and maintenance are convenient.

Description

technical field [0001] The invention relates to the technical field of marine engineering, in particular to a buoy structure suitable for floating tunnels. Background technique [0002] As a new sea-crossing and river-crossing scheme that takes into account traffic and the environment, the floating tunnel has many advantages such as being environmentally friendly, requiring low geological conditions, and not limited by water depth and span. Therefore, many countries in the world have launched research on it. From the structural point of view, floating tunnels are mainly divided into free type, buoy type, riveting type and pressure pier type. Among them, the buoy-type floating tunnel controls the ballast load and solid-empty ratio of the pipe body section, so that the buoyancy of the pipe itself is smaller than the gravity, and the top is connected to the buoy, and the vertical tension is provided by the buoy to ensure the stability of the structure. The buoy-type floating t...

AI Technical Summary

Problems solved by technology

This periodic reciprocating tidal load affects the stability of the main structure of the tunnel and can cause fatigue damage to the structure

At the same time, as a structure floating on the sea, its equipment control and energy input are not convenient enough, and daily maintenance is difficult
