Waterproof steel comb plate expansion joint system

Abstract

The invention relates to a waterproof steel comb plate expansion joint system. The expansion joint system is arranged on an expansion joint of two concrete beams and the concrete beams on both sides of the expansion joint, a C40 fiber concrete layer (9), a waterproof layer (4), a stainless steel slide plate (2) and a comb-shaped steel plate (1) are sequentially arranged on the concrete beams, theC40 fiber concrete layer (9) is provided with a gap with the same width at the corresponding position of the expansion joint, the waterproof layer (4) covers the C40 fiber concrete layer (9) and abovethe expansion joint, a water leakage monitoring system comprises a water leakage sensing cable (5), a signal converter (6) and a wireless signal transmitter (7) connected in series in sequence. Compared with the prior art, the waterproof steel comb plate expansion joint system solves the problems that the expansion joint of the traditional steel comb plate is leaky and can not be monitored in real time and manual monitoring is inaccurate, and the high-waterproof performance steel comb plate expansion joint can intelligently collect information, analyze and warn.

Description

Technical field [0001] The invention relates to a bridge monitoring technology, in particular to a waterproof steel comb plate expansion joint system. Background technique [0002] For most bridges, in order to meet the requirements of bridge deck deformation, expansion joints are set between two beam ends, between beam ends and abutments, or at the hinged position of the bridge. There are many types of bridge expansion joints. Among them, comb-tooth bridge expansion joints are widely used. [0003] The comb-tooth bridge expansion joint device has the advantages of low structure height, wide application range, stable driving, and anti-skid. However, the bridge expansion joint device will be exposed to the atmosphere for a long time, and will be affected by the impact load of the automobile, the internal force caused by the uniform settlement, and the natural environmental factors, which makes it the most vulnerable component in the bridge. The comb-tooth bridge expansion joint de...

Problems solved by technology

However, most of the comb-tooth expansion joints can only be monitored manually at this stage, which wastes manpower and material resources, and cannot be continuously monitored. The monitoring is only limited to the surface, and there may be missed judgments.
