A steel-concrete combined structure coal retaining wall in a circular coal yard and its construction method

Abstract

A circular coal yard steel-concrete composite structure coal retaining wall and its construction method. The coal retaining wall includes steel-concrete composite structure foundation or cap, reinforced concrete rib column, steel-concrete composite structure coal retaining wall, intermediate steel ring beam and reinforced concrete top ring beam, and the bottom of reinforced concrete rib column is steel-concrete Composite structure foundation or cap, the top is reinforced concrete top ring beam; reinforced concrete rib column and intermediate steel ring beam form a grid structure, which is used to support the coal-retaining wall of steel-concrete composite structure. The present invention also includes the construction method of the steel-concrete combined structure coal retaining wall of the circular coal yard. The steel-concrete combined structure coal retaining wall of the circular coal yard of the present invention has a reasonable structure. Compared with the traditional reinforced concrete integral coal retaining wall, it can reduce the amount of structural steel bars and reduce the workload of scaffolding and formwork.

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 that consider the use of steel structure coal retaining walls, such as CN 202249157 U. Although the amount of concrete work is reduced and the construction period is saved, the steel plate is in direct contact with ...

Problems solved by technology

[0003] There are also patents that consider the use of steel structure coal retaining walls, such as CN 202249157 U. 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, so it is very difficult to deal with fire prevention and anticorrosion, and the stiffness of steel structure coal retaining walls is generally lower than that of The concrete coal retaining wall is small, and the deformation of the steel plate is large in some coal pile conditions such as half coal pile conditions, 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, the significant cost increase
