A concrete pontoon bridge for a floating pier

Abstract

The invention belongs to the floating bridge field and in particular relates to a concrete floating bridge of a floating wharf. The concrete floating bridge of the floating wharf comprises a main bridge box, an auxiliary bridge box, a connecting rack and a pile type abutment; the main bridge box and the auxiliary bridge box are fixedly lapped on a seafloor pile by use of the connecting rack. The pile type abutment comprises a pile, a pile holder and a bridge box; the pile holder is fixed with the pile and comprises a pile holder main part, a pile holder auxiliary part, a roller and a roller bracket; the roller is fixed on the roller bracket and horizontally fixed on the pile holder. Six faces of the bridge box are all formed by use of reinforced concrete slabs and the reinforced concrete slabs of the bridge box are all coated with a silane anticorrosive material. The concrete floating bridge of the floating wharf is low in cost, high in safety performance, good in wave resistance, good in stability, excellent in durability, high in resistance to freezing and thawing, movable according to requirements and wide in application fields; the concrete floating bridge can be slightly modified into a floating airport for helicopters and a temporary floating wave barrier dam.

Description

technical field [0001] The invention belongs to the field of floating bridges, in particular to a concrete floating bridge for floating docks. Background technique [0002] At present, the existing floating dock pontoons in China are generally steel pontoon dock pontoons, high-density polyethylene pontoon composite dock pontoons, foamed concrete floating block composite dock pontoons, and aluminum alloy bridge box composite dock pontoons. However, the existing floating bridge has high cost, poor anti-aging performance, poor anti-wave stability, poor corrosion resistance, high maintenance cost and long-term maintenance. Although the concrete bridge box steel-wood composite wharf pontoon bridge that is close to foreign countries improves many properties of the existing pontoon bridge, the crack resistance of the concrete pontoon bridge, the corrosion resistance of steel materials and the water resistance, anti-wave stability and wave resistance of the concrete bridge box The ...
