Coal retaining wall for circular coal yards and method for constructing coal retaining wall
The invention discloses a coal retaining wall for circular coal yards and a method for constructing the coal retaining wall. The coal retaining wall for the circular coal yards comprises a foundation or bearing platform, a coal retaining wall body, a top ring beam, at least ten rib columns and at least two intermediate ring beams. Latticed structures are formed by the rib columns and the intermediate ring beams and are used for supporting the coal retaining wall body; annular unbonded prestressed tendons of the ring beams are arranged on the intermediate ring beams and the top ring beam, and annular unbonded prestressed tendons of the wall body are arranged in the coal retaining wall body. The coal retaining wall for the circular coal yards and the method for constructing the coal retaining wall have the advantages that the prestressed tendons are mainly arranged on the intermediate ring beams and the top ring beam, stretching ends of the prestressed tendons are arranged in a staggered manner at intervals, the prestressed tendons which are arranged at two ends of the coal retaining wall at intervals are tensioned after requirements on design strength are met by all concrete, and accordingly the integral coal retaining wall with prestress for the circular coal yards can be formed and can resist annular tensile force generated by stacked coal; annular bending moment of the coal retaining wall body can be effectively reduced and is no longer increased along with heightening of the coal retaining wall, and accordingly the coal storage can be increased advantageously by means of increasing the height of the coal retaining wall for the circular coal yards.
