A kind of pontoon and its using method, pontoon bridge

Abstract

The invention discloses a pontoon, a method for using it and a pontoon, and relates to the technical field of pontoons. The pontoon comprises: a plurality of pontoon units movably connected along the bridge, and each of the pontoon units is equipped with suction and drainage component, the suction and drainage assembly is configured to: when the water level outside the floating tank unit rises, the suction and drainage assembly absorbs water into the corresponding floating tank unit to keep the floating tank unit at a preset elevation; when the When the water level outside the floating tank unit drops, the suction and drainage assembly discharges the water in the corresponding floating tank unit to keep the floating tank unit at a preset elevation. The invention can make the mooring device and the telescopic device connected with the floating tank stable in force, not prone to fatigue damage, and is beneficial to the long-term safe operation of the floating bridge.

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
