AI Technical Summary
Technical Problem
The expansion joints of existing comb plates are easily blocked by mud and sand, and the nuts are loose or broken, resulting in limited expansion and contraction function, high maintenance costs, and difficult to clean and inspect.
Method used
A bridge dust-proof telescopic device without sediment accumulation and screws was designed, using interlaced comb plates and interceptor tank structures, combining U-shaped drainage tanks and cleaning pipes, anchoring components and clamp locking mechanisms to avoid sediment Clogging and bolt loose.
Benefits of technology
Effectively prevent silt and sand from entering, reduce cleaning and maintenance needs, reduce operating costs, and ensure long-term and effective operation of bridge expansion joints.

Abstract
The present invention discloses a bridge dustproof expansion and contraction device, comprising comb plates relatively arranged on both sides of an expansion joint, and the teeth of the two comb plates are arranged in a staggered manner, the teeth of the comb plates are located above the expansion joint, and the comb plates are provided with a water intercepting groove to prevent mud and sand from entering the teeth of the comb plates. The beneficial effects of the present invention are as follows: the comb plates are provided with a water intercepting groove, and most of the rainwater and mud and sand on the bridge surface are discharged to the outside of the bridge along the water intercepting groove, thereby playing a dustproof role, while a small amount of mud and sand and dust fall into the U-shaped drainage groove through the gap between the teeth, and are washed away by rainwater, thereby avoiding mud and sand from clogging the expansion joint, and ensuring the long-term effectiveness of the expansion and contraction function of the bridge; a cleaning pipe is provided, and the cleaning pipe can regularly clean the U-shaped drainage groove to ensure the reliability of the use of the U-shaped drainage groove; the comb plates adopt a screw-free design, which avoids the loosening and breaking of bolts, reduces the inspection times and inspection requirements of the bridge expansion joint, and reduces the operation cost of the expansion joint.
