Abstract

The invention relates to a bridge pier stud discrete material wrapped enlarged-section anti-scouring protection structure. The structure comprises annular notches, steel hoops, a radial wing plate, asemi-arc integral wing plate, a vertical limiting column, a vertical toothed plate and a U-shaped clamping and fastening device with a toothed plate. Pier body foundation enlarged-section scour prevention adopts a structure with an enclosing steel wire mesh for enclosing pouring gravel for protection or a structure with a sliding reduction steel wire mesh stone cage protection ring for protectionwith the periphery annularly and evenly distributed with vertical limiting columns. The annular notches are annularly and uniformly cut along the side surface of a bearing platform foundation of a pier body and are equidistantly arranged along the vertical direction; the steel hoops are arranged on the annular notches and are fixed through the vertical toothed plate and the U-shaped clamping and fastening device with the toothed plate; and pin holes of wing plates are formed at the top of the radial wing plate or the top of the semi-arc integral wing plate. The beneficial effects of the invention are that the steel hoops and a bottom supporting plate are simple and reasonable in structure, are convenient to assemble through the pluggable design, and improve the installation efficiency.

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...
