Concrete delivery pump pipe connection transfer structure and construction method thereof

Abstract

The invention relates to a concrete delivery pump pipe connection transfer structure and a construction method thereof. The concrete delivery pump pipe connection transfer structure comprises an original pump pipe, and a composite pump pipe communicating with the original pump pipe through a transfer pump pipe, wherein the transfer pump pipe is a steel pipe; the connecting end on one side of the transfer pump pipe is a buckle connecting end; the connecting end on the other side of the transfer pump pipe is a flange plate connecting end; the composite pump pipe is a double-layer composite pipeand comprises an outer pipe and an inner pipe; the outer pipe is a steel pipe; the inner pipe is made of ultra-high molecular weight polyethylene; and an annular flange plate of the composite pump pipe is connected with an annular flange plate at the flange plate connecting end through a flange bolt penetrating through a flange bolt hole in a bolting way. The concrete delivery pump pipe connectiontransfer structure provided by the invention solves the problems that a traditional conveying pump pipe buckle cannot be connected with the composite pump pipe, and the pipe diameters of a traditional conveying pump pipe and the composite pump pipe are excessive. The concrete delivery pump pipe connection transfer structure provided by the invention is tight in connection, excessive in pipe diameter so as to be straight and smooth, and favorable in concrete delivery effect.

Description

technical field [0001] The invention belongs to the field of concrete transportation and construction, in particular to a combined connection structure between different types of delivery pump pipes and a concrete pumping method thereof. Background technique [0002] Concrete pumping pipes for concrete structures in the construction industry are mainly made of steel pump pipes. Steel pump pipes will cause various problems during the concrete pumping process, such as pipe plugging or concrete performance changes. Especially in super high-rise pumping operations, these problems are more common due to the high pumping height and unstable performance of high-strength concrete. It seriously reduces the construction production efficiency, and quality problems are prone to occur if it is not handled in time. [0003] At the same time, there are still the following problems in the connection method for the concrete delivery pump pipe: [0004] 1. The traditional concrete delivery ...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to provide a concrete delivery pump pipe connection conversion structure and its construction method. It is necessary to solve the problem that the concrete steel pump pipe is blocked, the concrete performance changes seriously reduce the construction production efficiency, and the poor quality is easy to occur if the treatment is not timely. It is also necessary to solve the problem that the existing traditional buckle-connected pump pipes cannot be directly connected with special concrete delivery pump pipes. If the connection is not tight, it is easy to leak grout, and it is easy to cause safety accidents at the weak joints due to the pressure vibration of the pump truck, and the concrete Pouring quality control is difficult to guarantee and other technical problems
