Abstract

The invention provides a concrete column pouring method. The concrete column pouring method comprises the following steps of formwork plugging: mortar is adopted for conducting crack plugging treatment on the outer side of the bottom of a column formwork erected on the periphery of a column; tube stringing: binding a soft tube on a dust conveying hose of the concrete pump truck, and placing the soft tube at the central part of the column, so as to output column concrete through the rubber hose; and pouring: a layer of mortar is poured at the bottom of the column, pouring and vibrating are carried out on the column concrete layer by layer above the mortar layer, and the vibrating bar and the soft tube bound in the tube stringing step are lifted while pouring the column concrete in the pouring process. According to the method, the root rotting problem of the column is solved by adopting a mortar pre-pouring method, the segregation problem caused by large free fall of the column concreteis avoided by additionally adopting the tube stringing method, and the quality defects of concrete honeycombs, pitted surfaces and incompact vibration are further overcome by multi-point layered vibration during pouring.

Description

technical field [0001] The invention relates to the technical field of civil engineering in the metallurgical industry, in particular to a concrete column pouring method. Background technique [0002] When pouring large cross-section super high reinforced concrete columns, in order to ensure the quality of concrete column pouring, there are two conventional pouring methods, one is pouring at one time, and the other is pouring in multiple times. If pouring at one time, due to the concrete The free drop is large and the steel bars are dense, which is easy to cause concrete segregation, resulting in quality defects such as honeycomb, pockmarked surface, and insufficient vibration on the concrete surface after pouring. If pouring is performed in multiple times, the construction time of the column will be extended, resulting in a longer construction period. ,Increased costs. Contents of the invention [0003] In view of this, the present invention proposes a concrete column po...
