Coal retaining wall with steel-concrete combination structures for circular coal yards and method for constructing coal retaining wall

Abstract

The invention discloses a coal retaining wall with steel-concrete combination structures for circular coal yards and a method for constructing the coal retaining wall. The coal retaining wall comprises a foundation or bearing platform with the steel-concrete combination structures, reinforced concrete rib columns, a coal retaining wall body with the steel-concrete combination structures, intermediate steel ring beams and a reinforced concrete top ring beam. The foundation or bearing platform with the steel-concrete combination structures is arranged at the bottoms of the reinforced concrete rib columns, and the reinforced concrete top ring beam is arranged on the tops of the reinforced concrete rib columns; latticed structures are formed by the reinforced concrete rib columns and the intermediate steel ring beams and are used for supporting the coal retaining wall body with the steel-concrete combination structures. The coal retaining wall with the steel-concrete combination structures for the circular coal yards and the method for constructing the coal retaining wall have the advantages that the coal retaining wall is reasonable in structure, consumption of structure reinforcing steel bars can be reduced as compared with the traditional reinforced concrete integral coal retaining walls, and scaffold erecting and formwork workload can be reduced.

Description

technical field [0001] The invention relates to a steel-concrete combined structure coal retaining wall of a circular coal yard and a construction method thereof, belonging to the technical field of civil engineering structures. Background technique [0002] The circular coal yard currently built is generally a reinforced concrete integral coal retaining wall structure, which is characterized by the use of circumferential reinforcement to resist the horizontal thrust generated by the piled coal. The circumferential reinforcement of the coal retaining wall is generally controlled by cracks, which consumes steel The amount of work is huge, and the on-site construction of steel bar binding, scaffolding and formwork is a huge workload. [0003] There are also patents considering the use of steel structure coal retaining walls, such as CN202249157U. Although the amount of concrete work is reduced and the construction period is saved, the steel plate is in direct contact with the ...

AI Technical Summary

Problems solved by technology

[0003] There are also patents considering the use of steel structure coal retaining walls, such as CN202249157U. Although the amount of concrete work is reduced and the construction period is saved, the steel plate is in direct contact with the coal pile, and fire prevention and anticorrosion treatment is very difficult, and the stiffness of steel structure coal retaining walls is generally higher than that of concrete retaining walls. The coal wall is small, and the deformation of the steel plate is relatively large in some coal pile conditions such as the half coal pile condition, and the possibility of buckling of the steel plate increases. If the deformation is reduced and the stiffness of the steel structure coal retaining wall is increased, it will increase significantly. cost
