Technical Field
The invention relates to the field of bridge construction, in particular to a fracture surface repairing method for maintaining a viaduct.
Background
Viaducts, i.e. overpasses, a type of bridge. In particular to a bridge which is laid on a series of narrow reinforced concrete or masonry arches, has a high-support tower or pillar, and spans a valley, a river, a road or other low obstacles. After the city is developed, the traffic is crowded, the buildings are dense, the streets are difficult to widen, and the traffic density can be evacuated by adopting the bridge, so that the transportation efficiency is improved. In addition, in the case of highways or railways between cities, such bridges are used in order to avoid crossing with other line levels, save land, reduce subgrade settlement (in some areas), or to eliminate the need for embankments. The viaduct not only refers to a physical bridge, but also is compared with difficulties, frustrations and the like.
The superstructure of the overhead line bridge generally adopts a simple beam or a continuous beam (or a rigid frame), and a cantilever beam is rare. When the simply supported beam is used, the simply supported beam with continuous bridge deck is often made in order to ensure smooth travelling of the bridge deck. If the continuous beam and the pier top are rigidly connected, the continuous rigid bridge is formed. When the span of the bridge is not large, two sides of the box-shaped section extend out of the bridge deck to enlarge the bridge deck, and a narrow pier is used below the box-shaped section to form a spine-type structure.
Along with the extension of the service life of the viaduct, a bridge deck can generate certain broken joints under long-term heavy pressing, the formation of the broken joints needs to be repaired in time, the expansion of the broken joints is restrained, the existing crack repair usually needs to coat a plurality of layers of repairing agents on the cracks, the repair construction is carried out layer by layer, the efficiency of the crack repair mode is low, and the influence on the traffic smoothness is large.
