Pipe clamp supporting structure and construction method for long-distance pumping of machine-made sand concrete

Abstract

The invention discloses a pipe clamp supporting structure. The pipe clamp supporting structure comprises a supporting table, wherein the supporting table is provided with first hydraulic rods and a second hydraulic rod, and the first hydraulic rods are fixedly connected with a servo motor, a driving shaft, a driving gear and a gear ring; an input pipeline is connected with an oval material pipe Ithrough an input pipe clamp, the input pipe clamp comprises angle iron and an annular strip block, and the annular strip block is provided with an annular clamping groove and a flange hole; an outputpipeline is connected with an oval material pipe II through an output pipe clamp, and an oval material pipe III is arranged between the oval material pipe I and the oval material pipe II; and the outer wall of the oval material pipe III located in the middle is sleeved with a round supporting ring, the round supporting ring is fixedly connected with a spring rod, the spring rod is riveted to a horizontal fixing rod and an inclined swing rod, and a third hydraulic rod is riveted between the horizontal fixing rod and the inclined swing rod. The invention further provides a construction method for long-distance pumping of machine-made sand concrete. According to the pipe clamp supporting structure, two aspects of adjustment of a machine-made sand concrete formula and a pumping structure are synthesized, the problem of long-distance pumping of the concrete is thoroughly solved, and the pipe clamp supporting structure is suitable for pumping of 300 m or above.

Description

technical field [0001] The invention relates to the technical field of concrete pumping, in particular to a pipe clamp support structure and a construction method for long-distance pumping of machine-made sand concrete. Background technique [0002] In recent years, with the rapid increase of engineering construction and the scarcity of natural sand resources, it is imperative to replace natural sand with machine-made sand. According to research, Anhui Province has abundant mineral resources such as limestone and granite, and they are easy to mine. Therefore, in Limestone machine-made sand is often used as fine aggregate in highway and waterway projects. The scientific and reasonable use of machine-made sand can not only improve the working performance and mechanical properties of concrete, but also greatly reduce the construction cost. Therefore, construction units in Anhui Province gradually use machine-made sand instead of natural Sand for road and waterway construction. ...

Problems solved by technology

[0003] However, compared with natural sand, the particles of machine-made sand are relatively rough, and it also contains certain stone powder, which makes the viscosity of machine-made sand concrete relatively large, which will affect the actual performance of machine-made sand concrete during long-distance pumping.
