Embodiment Construction

[0033] Examples see figure 2 As shown, this concrete jacking backflow system includes a concrete delivery pump 1 and a concrete delivery pipeline, and the concrete delivery pipeline includes a delivery pipe standpipe 2, a delivery pipe main pipe 3 and a delivery pipe branch pipe, wherein the delivery pipe main pipe 3 and the delivery pipe The branch pipes are all spliced ​​by single-section pipes.

[0034] The number of the delivery pipe branches is the same as the number of steel pipe columns that need to be lifted, at least two, the delivery pipe main pipe 3 communicates with the first delivery pipe branch 4 in the delivery pipe branch, and the first delivery pipe branch 4 is in turn The check valve of the steel pipe column communicates with the hole on the lower pipe wall of the first steel pipe column 5 in the steel pipe column. Through the check valve of the steel pipe column, it communicates with the hole on the lower pipe wall of the remaining steel pipe column; the m...

Abstract

The invention discloses a concrete jacking and refluxing system and a construction method thereof. The concrete jacking and refluxing system comprises a concrete conveying pump and a concrete conveying pipeline, wherein the concrete conveying pipeline comprises a conveying pipe vertical pipe, a conveying pipe main pipe and conveying pipe branch pipes; the quantity of the conveying pipe branch pipes is the same as that of steel pipe columns which are required to be jacked; the conveying main pipe is communicated with a first conveying pipe branch pipe in the conveying pipe branch pipes; the first conveying pipe branch pipe is communicated with a hole on the lower pipe wall of a first steel pipe column in the steel pipe columns through a steel pipe column check valve; the conveying pipe main pipe is communicated with other conveying pipe branch pipes through main pipe current dividers; and the other conveying pipe branch pipes are communicated with holes on the lower pipe walls of the other steel pipe columns through steel pipe column check valves. According to the concrete jacking and refluxing system and the construction method thereof, concrete waste caused by pipe detachment in the conventional concrete jacking process is reduced, the construction period is saved simultaneously, the construction efficiency in unit time is increased, and the pump pipe blocking probability is lowered.

Description

technical field [0001] The invention relates to a steel pipe concrete jacking system used in building construction and a method for concrete jacking construction using the steel pipe concrete jacking system. Background technique [0002] Concrete jacking construction technology is applied to the construction of steel tube concrete members in large buildings. Concrete-filled steel pipe members are formed by filling self-compacting concrete in steel pipes, and the steel pipes and their core concrete bear external loads (forces) together. As we all know, concrete has high compressive strength, but its bending resistance is very limited, while steel, especially section steel, has strong bending resistance and good elastic-plastic properties, but it is easy to lose stability and lose axial compressive capacity when it is under compression. Concrete-filled steel tube members combine the advantages of the two, so that the concrete is in a three-way compression state, and its compr...
