Concrete grouting conveying device for high-rise building construction

Abstract

The invention discloses a concrete grouting conveying device for high-rise building construction, which includes an inlet assembly, several segments, several feeding pumps, connecting pipes, grouting pipes and a support frame, the inlet assembly includes a feeding hopper and a feeding elbow, and Both the hopper and the feeding elbow are supported by the support frame and installed on the foundation. The bottom of the hopper is connected to one end of the feeding elbow. The segments are stacked vertically and fixed with each other by fasteners. Clamp installation, the pumping direction of the feeding pump is from bottom to top, the bottom of the lowermost section is connected to the other end of the feeding elbow, and the connecting pipe is used to connect the top of the uppermost section and one end of the grouting pipe; the section The section includes section pipe, which is a section of cylinder with flanging; the spliced ​​conveying device can continuously increase in height with the construction of the building; while the feeding pump is pressurized and conveyed, finely crushed concrete is drummed into the concrete The gas helps to mix and refine the internal structure of the concrete.

Description

technical field [0001] The invention relates to the field of high-rise construction auxiliary devices, in particular to a concrete grouting conveying device for high-rise building construction. Background technique [0002] Concrete is a very important material in construction. Concrete in a fluid state is injected into the design position and solidified as a high-rise structure. [0003] In the prior art, the concrete of a high-rise building is usually transported by a cement pump truck. The pump truck directly pressurizes the fully mixed concrete from the ground and transports it to a distant place through a set of connecting rod structures. It requires a lot of pressure to transport concrete on the building floor. The delivery pipe has high pressure requirements and a large wall thickness. Moreover, the pump truck takes up a lot of space during operation and is not suitable for long-term parking on the construction site. [0004] The high-pressure transportation of pump ...

AI Technical Summary

Problems solved by technology

[0004] The high-pressure transportation of pump trucks on the ground is almost always hydraulic equal-volume transportation. Because the pressure head is high and the viscosity of concrete is relatively high, centrifugal slurry pumps cannot meet the needs of use, while positive displacement pumps are used in concrete. The output end is intermittently output, and the outlet fluid is carried out intermittently, so the vibration is very large, which not only increases the fatigue damage of the output end, but also may make the injection position deviate
