Buoyancy tank, using method thereof and floating bridge

Abstract

The invention discloses a buoyancy tank, a using method thereof and a floating bridge, which relate to the technical field of floating bridges. The buoyancy tank comprises a plurality of buoyancy tankunits movably connected along a bridge, a water suction and drainage assembly is arranged in each buoyancy tank unit in a matched mode, and the water suction and drainage assemblies are configured inthe mode that when the water level outside the buoyancy tank units rises, the water suction and drainage assemblies suck water into the corresponding buoyancy tank units so that the buoyancy tank units can be kept at a preset elevation, and when the water level outside the buoyancy tank units descends, the water suction and drainage assemblies drain water in the corresponding buoyancy tank unitsso that the buoyancy tank units can be kept at the preset elevation. The mooring device and the telescopic device which are connected with the buoyancy tank can be stressed stably, fatigue damage is not prone to occurring, and long-term safe operation of the floating bridge is facilitated.

Description

technical field [0001] The invention relates to the technical field of pontoon bridges, in particular to a pontoon tank, a method for using the same, and a pontoon bridge. Background technique [0002] Floating bridges are an ancient type of bridge. Floating bridges are not as convenient as ordinary bridges in operation. At present, floating bridges are mostly used for emergency rescue, emergency passage of military facilities, or temporary construction for seasonal traffic needs. However, for special site conditions, such as deep water depth (generally greater than 60m), or site conditions with thick covering layers, the general bridge structure does not meet the construction conditions, and a permanent pontoon bridge must be built. [0003] In related technologies, in order to overcome the rise or fall of the main bridge body caused by tidal changes, the permanent floating bridge divides the entire floating bridge into a floating body section, a shore fixed section, and a ...

Problems solved by technology

[0004] However, tides are generally divided into semi-diurnal tides, diurnal tides, mixed tides, etc. The water level changes greatly and the cycle is short. The long-term periodic up and down large displacement movement of the floating body section causes the mooring device and telescopic device to be subjected to a large reciprocating force for a long time. Very prone to fatigue damage, which is not conducive to the long-term safe operation of the floating bridge
