Problems solved by technology

The existing PE pipe jacking socket interface, because only half of the thickness of the inner and outer interfaces is left after processing, the performance of bearing the jacking force is greatly reduced, and the interface is easy to be damaged. When connecting the PE pipe, a jack is generally used to put the pipe together. It is easy to damage the docking interface when docking.

Embodiment 1

[0019] Embodiment 1: as Figure 1 to Figure 4 As shown, in the pipe mortise and tenon structure described in this embodiment, the two ends of each pipe 1 are respectively provided with butt joints 2, and the butt joints 2 include a plurality of protrusions 3 and notches 4 arranged alternately. The end surface of the bump 3 and the bottom of the notch 4 are flat and perpendicular to the length direction of the pipeline 1, and the height of the bump 3 is equal to the depth of the notch 4, so that when the bump 3 is matched with the notch 4, the bump 3 can It is evenly pushed up to the bottom of the notch 4, and its pressure-bearing performance is improved by increasing the force-bearing surface. Two pairs of joints 2 are used for docking between two adjacent pipes 1, and the protrusion 3 on one pair of joints 2 cooperates with the notch 4 on the other pair of joints 2. After the two butt joints are butted, a The sealing ring 5 is used for sealing, and the sealing ring 5 is made...

Embodiment 2

[0024] Embodiment 2: Refer again Figure 5 , with respect to embodiment 1, its difference is that: each pipe 1 two ends are provided with protruding strip 11 and groove 12 respectively, and protruding strip 11 and groove 12 cooperate with each other, improve the gap between two pipes 1 like this. The tightness of the interface.

Abstract

The invention provides a pipeline mortise and tenon joint structure. The two ends of each pipeline are provided with butt joints correspondingly, the butt joints comprises a plurality of interphase convex blocks and notches, the end faces of the convex blocks and the bottoms of the notches are both flat and perpendicular to the length direction of the pipelines, the heights of the convex blocks are equal to the depths of the notches, the two butt joints are butted between every two adjacent pipelines, the convex blocks on one butt joint are matched with the notches on the other butt joint, andafter two butt joint ports are butted, and the outer sides of the butt joint ports sleeve with a sealing ring. Due to the fact that the convex blocks and the notches of the parallelogram are arrangedon the two butt joints respectively, the pipelines are not easy to rotate after being buried, so that the pipelines can be prevented from loosening and leaking due to the axial pulling force, the butt joint surfaces of the convex blocks and the notches are flat and perpendicular to the length direction of the pipelines, the thickness of the convex blocks is almost equal to the thickness of the pipelines, so that the jacking force which can be borne at the butt joint ports is large, and the butt joints are not easily damaged.

Description

technical field [0001] The invention relates to the technical field of pipelines, in particular to a pipeline mortise and tenon structure. Background technique [0002] The butt joint structure of existing pipelines such as Figure 6 , Figure 7 As shown, the pipe jacking interface of the existing cement pipe is relatively simple. The ends of the two cement pipes are bound with steel rings to realize the butt joint without fastening structure. The joints are easily disjointed, misplaced and leaked due to the vibration of the ground traffic. In addition, if the pipe is used After a long time, the two pipe joints will be dislocated or separated after the steel ring used for connection decays. The existing PE pipe jacking socket interface, because only half of the thickness of the inner and outer interfaces is left after processing, the performance of bearing the jacking force is greatly reduced, and the interface is easy to be damaged. When connecting the PE pipe, a jack is g...
