Problems solved by technology
However, occasionally, the mandrel cannot be pulled out due to deformation or slurry leakage of the prestressed corrugated pipe, and it will break under mechanical pulling
If the broken mandrel is blocked in the prestressed corrugated pipe and cannot be taken out, subsequent construction such as steel beam tensioning cannot be carried out, resulting in the failure of the beam body to meet the use requirements, and the mandrel can only be drilled to take out the mandrel or even the beam body will be abandoned, causing great losses

The invention discloses a cleaning device for mandrel rods in prestressed corrugated pipelines of PC components, which comprises a splitting mechanism, a collecting mechanism and a traction mechanism. The splitting mechanism includes a first rope fixing ring, a second rope fixing ring, a base column, an outer sleeve, a splitting blade and an axis fixing steel bar. Taking the vertical direction of the base column as a reference, the first rope fixing ring and the second rope fixing ring respectively Welded and fixed at both ends of the base column, the first rope fixing ring is located above the second rope fixing ring, the outer sleeve is hollow, the base column is located on the axis of the outer sleeve, the splitting blade is evenly wrapped around the outer wall of the base column, and the axis is fixed One end of the vertical direction of the steel bar is welded and fixed to the base column, the other end of the vertical direction of the axis-fixed steel bar is welded and fixed to the outer sleeve, the top of the axis-fixed steel bar is fixedly connected to the splitting blade, and the splitting blade is fixed around the outer sleeve On the outer wall, the splitting blade extends outward from the hypotenuse of the base column to form a sharp edge.
Description
technical field [0001] The invention relates to the technical field of PC component prestressed construction auxiliary tools, in particular to a cleaning device for mandrels in PC component prestressed corrugated pipes. Background technique [0002] With the popularization of prestressed bridge construction technology, prestressed corrugated pipes commonly exist in various bridge components. During the construction of prestressed bridges, a mandrel (usually a thick-walled hollow tube made of plastic material) will be placed in the prestressed corrugated pipe before concrete is poured to enhance the compressive performance of the hollow prestressed corrugated pipe and prevent prestressing. The corrugated pipe is deformed or leaked. After the concrete reaches the strength, the mandrel is pulled out to carry out the threading and tensioning of the prestressed steel bundles. However, occasionally, the mandrel cannot be pulled out due to the deformation of the prestressed corru...
