Drainage pipeline butt joint device and method

Abstract

The invention discloses a drainage pipeline butt joint device and method. According to the main technical scheme, the drainage pipeline butt joint device comprises a base, at least two sliding frames arranged on the base and a hot melting structure arranged on the base; the sliding frames are provided with positioning round rods used for limiting a pipeline in the circumferential direction and the axial direction at the same time, positioning pieces used for being fixedly connected to the pipeline are inserted into the positioning round rods in the radial direction of the pipeline, and at least one of the sliding frames is connected to the base in a sliding mode; the hot melting structure is detachably connected to the base and used for heating the end of the pipeline. The drainage pipeline butt joint device and method have the following effects that the positioning round rods are matched and connected with the positioning pieces in the inserted mode, the positioning round rods are mainly used for achieving the positioning function, the positioning pieces can limit the pipeline in the circumferential direction and the axial direction, the acting force of the positioning pieces is not in the radial direction, the possibility of pipeline deformation in the hot melting butt joint process is reduced, and the quality is improved.

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...

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
