Apparatus and method for lifting up, compacting and forming concrete in steel-pipe column (wall)

Abstract

The invention provides an apparatus and a method for lifting up, compacting and forming concrete in a steel-pipe column (wall). The apparatus comprises the following components: a material pressing structure node, a counter current preventing apparatus, a pressure regulating apparatus, and a pumping system; the material pressing structure node is arranged at the side surface of the bottom of the steel-pipe column (wall), and the material pressing structure node is connected to the counter current preventing apparatus, the pressure regulating apparatus, and the pumping system in order. The pumping system is used, a pressure conveying principle is used in order to lift concrete from the bottom of the steel-pipe column (wall) to the top of the column (wall), and the concrete is compacted and formed in the steel-pipe column (wall) by pressure. The apparatus and the method for lifting up, compacting and forming concrete in the steel-pipe column (wall) use local materials for processing and producing, pressure in a transfer pump is used for carrying out the lifting-up work for the concrete, so that the common concrete reaches effects of self-compaction concrete, and the apparatus and the method have the advantages of substantially reduced construction cost, simple operation, good quality, low cost, and substantial economic effects; the apparatus and the method can be applied to concrete construction of various steel-pipe columns (walls) with application and promotion values.

Description

technical field [0001] The invention relates to a construction measure device, in particular to a steel pipe column (wall) concrete jacking and compacting forming device and method. Background technique [0002] There are three main methods of concrete pouring for steel pipe columns (walls): one is manual pouring and pounding. The construction speed of this method is slow, and the construction organization is complicated, and the vibration work is heavy. It is widely used in the early concrete construction of steel pipe columns (walls). The second is the high-level drop-free vibration method. Utilize the kinetic energy of commercial concrete falling along the steel pipe from high altitude to achieve the purpose of compacting commercial concrete, which can save or reduce the heavy vibration work, but this method is suitable for the situation where the pipe diameter is not less than 300mm and the height is not more than 5m, and it is easy to cause The core commercial concrete...
