AI Technical Summary

Technical Problem

Traditional bridges have limited waterproofing capabilities and insufficient structural stability, making them unable to adapt to temperature changes and deformations caused by vehicle loads, and prone to cracking and stress concentration.

Method used

The structure employs multiple layers of waterproofing and sealing measures, including high-density polyethylene sheets, rubber bearings, anchoring steel bars, and structural steel sections. Expansion joints and continuous joints are designed to allow the bridge to expand and contract freely. Combined with high-quality asphalt concrete layers and rubber sealing materials, the structure's stability and waterproofing performance are enhanced.

Benefits of technology

It effectively prevents water penetration, enhances structural stability, reduces stress concentration, extends the service life of bridges, and improves driving comfort and safety.

Abstract

The utility model relates to a bridge for communicating highways on two sides of a river channel, which comprises a plurality of groups of piers, a plurality of rubber supports and a plurality of connecting pieces, the bridge deck slab is arranged at the tops of the two adjacent sets of bridge piers and supported through rubber supports and comprises a plurality of hollow slab beams which are arranged side by side in the length direction of the bridge, a hinge joint is arranged between every two adjacent hollow slab beams, an anchor bolt structure connected with a bridge pier cover beam is arranged in each hinge joint, and a waterproof buffer structure is arranged at a continuous joint on the bridge deck slab. A telescopic structure is arranged at the expansion joint between the bridge spans; the bridge deck pavement concrete layer is poured on the top of the bridge deck slab, and the hinge joint is filled; the medium-grain asphalt concrete layer is poured on the top of the bridge deck pavement concrete layer; and the fine grain type asphalt concrete layer is poured on the top of the medium grain type asphalt concrete layer. Compared with a traditional bridge, the overall performance and durability are improved, and the using effect is good.
