Pre-stress pipeline dredging device as well as a manufacturing and application method thereof

Abstract

The invention discloses a pre-stress pipeline dredging device as well as a manufacturing and application method thereof. The dredging device comprises a cone and a steel pipe connected with the bottom of the cone; a small hole is formed in the top of the cone and a steel strand is fixed through the small hole. The manufacturing and application method comprises the steps of manufacturing the dredging device, threading and fixing the steel strand through the small hole at the top of the cone in the dredging device, pulling the dredging device into a pre-stress pipeline by using the steel strand and enabling the dredging device to pass through the pipeline and the like. The pre-stress pipeline dredging device has the advantages of simple structure, convenience for arrangement, rapidness in dredging and good effect; the working requirements of all aspects of the dredged pre-stress pipeline are ensured; the pre-stress pipeline dredging device is good for repeated utilization and the construction cost is reduced.

Description

technical field [0001] The invention relates to a pipeline dredging device, more specifically, the invention relates to a dredging device used for prestressed pipelines in the bridge construction process and a method for making and using the same. Background technique [0002] In the process of bridge construction, prestressed construction is an indispensable link, and the dredging of prestressed pipelines is therefore more important. [0003] The current prestressed construction is mostly carried out by post-tensioning method. This prestressed construction method has the following shortcomings and deficiencies: [0004] (1) Since the prestressed pipeline is subject to the dual action of the vibrating force of the vibrating rod and the concrete pressure during concrete pouring, it is easy to cause damage to the prestressed pipeline; [0005] (2) If the prestressed pipe is damaged, it will cause the newly poured concrete to leak into the prestressed pipe from the damaged pla...

AI Technical Summary

Problems solved by technology

[0004] (1) Since the prestressed pipeline is subject to the dual action of the vibrating force of the vibrating rod and the concrete pressure during concrete pouring, it is easy to cause damage to the prestressed pipeline;

[0005] (2) If the prestressed pipe is damaged, it will cause the newly poured concrete to leak into the prestressed pipe from the damaged place and make it condense in the prestressed pipe;

[0006] (3) If the leaked concrete congeals into blocks in the prestressed pipeline, it will block the pipeline and affect the penetration of the prestressed steel bars, thereby causing unnecessary trouble, prolonging the construction time, and even increasing the construction cost
