Steel-concrete joint waterstop of corrugated steel web plate composite girder bridge

Abstract

The invention belongs to the technical field of steel-concrete joint waterstop, particularly relates to a steel-concrete joint waterstop of a corrugated steel web plate composite girder bridge. The steel-concrete joint waterstop of the corrugated steel web plate composite girder bridge comprises corrugated steel web plates, a corrugated steel web plate composite girder concrete bottom plate and acorrugated steel web plate composite girder concrete top plate, wherein the upper and lower ends of the corrugated steel web plates are separately embedded between the opposite side walls of the corrugated steel web plate composite girder concrete bottom plate and the corrugated steel web plate composite girder concrete top plate. The steel-concrete joint waterstop is convenient to prefabricate, low requirements in site conditions, and is particularly suitable for field operations. According to the reserved grooves of the steel-concrete joint waterstops, secondary damage to the structure caused by grooving after the completion of construction of the corrugated steel web plate bottom plate and web plates is reduced, and rainwater is prevented from eroding the joint by sequentially adheringa putty composite rubber sealing strip, a water-swellable rubber sealing strip and a ethylene-propylene-diene monomer sealing rubber strip from top to bottom to form a tight joint with the corrugatedsteel web plates and the concrete bottom plate.

Description

technical field [0001] The invention relates to the technical field of steel-concrete junction waterstops, in particular to a steel-concrete junction waterstop of a corrugated steel web composite girder bridge. Background technique [0002] Bridges generally appear in the construction of expressways, high-speed railways and urban viaducts. On the one hand, it is convenient to alleviate traffic congestion, and on the other hand, it improves traffic safety. Bridge construction has become the top priority of road construction. [0003] In the construction and design of existing corrugated steel web composite girder bridges, the water-proof and waterproofing of the steel-concrete junction is ignored, but in actual engineering, the junction of the concrete base plate and the corrugated steel web will inevitably have rainwater seepage; Exposure to the atmosphere, with the passage of time, the weathering and spalling of the bottom slab concrete will cause rainwater to seep into th...
