The utility model provides an utilize corrugated steel of high strength grouting material to strengthen encircleing, includes supporting layer and grouting material layer, the supporting layer is installed in bridge bottom surface below, is formed by the equipment of a plurality of corrugated steel, the grouting material layer is filled between supporting layer and bridge bottom surface, the supporting layer lower extreme is provided with the reinforcement base.
Further, the radian of the supporting layer is the same as that of the bottom surface of the bridge.
Further, the distance between the support layer and the bottom surface of the bridge is 150 mm.
Furthermore, longitudinal steel bars and circumferential steel bars are inserted into the supporting layer in a penetrating mode, and the longitudinal steel bars and the circumferential steel bars are arranged in a vertically staggered mode.
Furthermore, the corrugated steel adopted by the supporting layer is prefabricated in a factory, bolt holes are prefabricated in two sides of the corrugated steel, and the corrugated steel is assembled in a bolt connection mode on site.
Furthermore, shear nails are prefabricated at wave crests and wave troughs of the corrugated steel.
Furthermore, the grouting material layer adopts high-strength grouting material with early strength, self-leveling and micro-expansion, the strength is C40 or C60, and the grouting material layer is grouted by a pressure grouting pump.
The utility model has the main advantages that: the utility model discloses a corrugated steel reinforcing arch using high-strength grouting material, which is used for reinforcing an old bridge, and on one hand, the bearing capacity of the original structure of the old bridge can be greatly improved, so that the old bridge can recover the use function; on the other hand, the reinforcing method is low in cost and convenient and fast to construct, and the reinforced structure is harmonious with surrounding landscapes.
