Drainage pipe docking device and docking method

Abstract

The application discloses a drainage pipe docking device and a docking method. The main technical solution is a drainage pipe docking device, which includes a base, a sliding frame arranged on the base, and a hot-melt structure arranged on the base; the sliding The frame is provided with a positioning round rod for simultaneously limiting the pipe in the circumferential direction and the axial direction. The positioning rod is inserted along the radial direction of the pipe with a positioning piece for fixed connection on the pipe. The sliding frame There are at least two, and at least one of the sliding frames is slidably connected to the base; the hot-melt structure is detachably connected to the base for heating the end of the pipeline. The application has the following effects: the positioning round rod cooperates with the plug-in positioning part. The positioning round rod mainly realizes the positioning function. The possibility of pipe deformation during the fusion butt joint process improves the quality.

Description

technical field [0001] The present application relates to the technical field of pipe butt joint devices, in particular to a drain pipe butt joint device and a butt joint method. Background technique [0002] During the construction of municipal construction, it is necessary to repair and transform the underground pipelines. The previous drainage pipes are often in an unreasonable direction and need to be readjusted; or the original drainage pipes with smaller diameters need to be replaced. [0003] During the construction process, due to the long length of the direction, multiple pipes need to be spliced ​​before they can be connected, and the two pipes need to be connected. Now the main technology used is to clamp and fix the two pipes that need to be connected. Since the original pipe is generally fixedly connected to another installed pipe, it is necessary to butt the newly added pipe with it in the axial direction. After the butt connection is completed, heat the ends...

AI Technical Summary

Problems solved by technology

[0004] Regarding the related technologies mentioned above, in the actual docking process, the main thing that needs to be ensured is that the circumferential direction of the pipe cannot be rotated, so a large clamping force will often be applied to the pipe, and the purpose is achieved by increasing the static friction force, but in this way It is easy to cause the pipe to deform in the radial direction, resulting in the deformation of the outer wall of the pipe formed after the butt joint is completed, which affects the subsequent use of the pipe, and may cause the pipe to be easily damaged in severe cases
