Abstract

The invention relates to an anti-scouring protection structure of bridge pier columns wrapped with bulk materials and enlarging the cross-section, including circular notches, steel hoops, radial wing plates, semi-arc integral wing plates, vertical limit columns, and vertical teeth. plate and U-shaped clamping and fastening device with toothed plate; the anti-scouring of the enlarged section of the pier body foundation adopts the enclosing steel wire mesh to enclose the perfusion gravel protection structure or the ring-shaped and evenly distributed vertical limit column slide-down steel wire mesh Gabion retainer protection structure; the annular notch is evenly cut along the circumferential direction of the foundation side of the pier body cap and arranged equidistantly along the vertical; the steel ferrule is placed on the annular notch and passed through The vertical tooth plate and the U-shaped fastening device with the tooth plate are fixed; the top of the radial wing plate or the semi-arc integral wing plate is provided with a pin hole of the wing plate. The beneficial effects of the present invention are: the steel hoop and the bottom supporting plate adopted in the present invention have a simple and reasonable structure, the plug-in design is convenient for assembly, and the installation efficiency is improved.

Description

technical field [0001] The invention relates to an anti-scouring protective structure with enlarged cross-section wrapped by bulk materials of bridge piers and columns and a construction method, which belongs to the field of civil engineering and is suitable for open cut and enlarged foundation renovation of slope excavation on land and in water where cofferdams have been completed. Background technique [0002] The foundation of the bridge bears all the weight of the piers, the bridge span structure (bridge body) and the variable action on the bridge. Bridge foundations are often built in the flowing water of rivers and are subject to the erosion of water flow. Therefore, the bridge foundation is generally larger than the house foundation, and there are many problems to be considered, and the construction conditions are also difficult. [0003] After the bridge is completed, during the use of the pier foundation, due to the aggravation of the load of the vehicles passing t...
