The invention discloses a rapid reinforcing method for bridge deck pavement based on a UHPC-steel mesh composite layer, and belongs to the technical field of bridge engineering reinforcement. According to the method, a scientific disease grading evaluation system is combined with key part correlation analysis to optimize the reinforcement range, reinforcement requirements of different disease areas are accurately matched, and combined with base surface treatment, steel mesh positioning and UHPC material modification processes, collaborative stress of a composite layer, an original base layer and a steel mesh and composite application of the UHPC material and modified steel fibers are enhanced, so that the comprehensive performance of the composite layer is improved. The impermeability, corrosion resistance and mechanical property uniformity of the composite layer are improved, the service cycle of the bridge deck is prolonged, and the bearing performance and damage resistance of the bridge deck are remarkably improved; and meanwhile, the layered pouring and adaptive vibrating technology is combined with the steam rapid curing technology, the construction and curing period is greatly shortened, interference to traffic passing is reduced, the later repair rate is reduced through the precise detection and control technology, the maintenance investment is reduced, and balance of the reinforcing effect and economic benefits is achieved.

The application belongs to the technical field of retaining walls, and particularly relates to a combined counterweight retaining wall and a construction method thereof, which comprises a retaining wall, the side surface of the retaining wall is fixedly connected with a clamping assembly mechanism, the front surface of the retaining wall is fixedly connected with an arc-shaped plate, and the inner side wall of the arc-shaped plate is fixedly connected with an anti-extrusion mechanism; the clamping assembly mechanism is provided, the self-weight of the counterweight structure is used to stabilize the base and is matched with the mechanical interlocking constraint, a self-weight and interlocking double anti-sliding and anti-overturning system is formed, the counterweight structure can resist soil side pressure, earthquakes or uneven settlement more than a single structure, the clamping assembly mechanisms are mutually embedded to form integral stress, block misplacement and sliding are avoided, even if local stress concentration occurs, the clamping assembly mechanisms will not cause chain collapse, the risk resistance of the structure is improved, in addition, after the interlocking blocks are tightly engaged, the gap is extremely small, the rainwater can be effectively blocked from penetrating into the wall body by cooperating with the fence grid and the drainage groove plate, backfill soil softening and water and soil loss are avoided, and the counterweight platform and the foundation stability are protected.
