Abstract

The present invention relates to the field of stabilization with the aid of reinforced-concrete column structures, in particular to a steel-tube grouting quick-stabilization column structure and construction method. The cross-section of steel-tube grouting quick-stabilization column structure may be either round or square. A round-section steel-tube grouting quick-stabilizing column structure comprises two outer-casing semi-round steel tubes and ring-type restriction stirrups, and a square-section steel-tube grouting quick-stabilizing column structure comprises two outer-casing semi-round steel tubes and square restriction stirrups. The two outer casing steel tubes adopted by the present invention can double as formwork so as to avoid field formwork construction. The construction techniques only require installing and securing the semi-steel tubes on the field and injecting the high-strength grouting material, so the operating process is quite simple. Welding the two semi-steel tubes after the grouting material is injected can avoid the partial buckling of steel-tube wall caused by welding operation and the high requirements for skilled welders; therefore, it is quite simple and easy to implement the stabilization technique.

Description

technical field [0001] The invention relates to the field of reinforced concrete column structure reinforcement, in particular to a steel pipe grouting rapid reinforcement column structure and a construction method. Background technique [0002] In actual engineering, the bearing capacity of reinforced concrete columns is often insufficient due to structural design changes, quality defects during construction, natural disasters, aging, etc. At this time, reinforced concrete columns need to be reinforced. At present, there are many reinforcement methods for reinforced concrete columns, including methods such as enlarging the section, outsourcing steel, and carbon fiber reinforcement, but there are disadvantages such as complicated construction procedures, slow construction speed, or large section of reinforced columns. For this reason, the steel pipe grouting rapid strengthening column structure and construction method are proposed to quickly strengthen the reinforced concr...
