Embodiment 2

[0051] A method for setting the shear structure of a ductile iron pipe joint, which is used to set the shear structure of the ductile iron pipe joint described in Embodiment 1, includes the following specific steps:

[0052] S1. Excavating the trench 1, and cleaning and leveling the trench 1, wherein both sides of the trench 1 have outwardly expanding slopes 11;

[0053] S2. Drill holes downward at the bottom of the groove to form reinforcement holes 12. The reinforcement holes 12 are arranged at intervals along the direction of the groove 1. At the same time, positioning columns are inserted into the reinforcement holes 12, and concrete is injected into the positioning columns to form concrete columns;

[0054] S3, set up the supporting frame 4 on the piercing end 33 of the positioning column;

[0055] S4, hoisting the pipeline 2 and making the pipe wall of the pipeline 2 and the supporting frame 4 offset to realize the installation;

[0056] S5. Backfill the soil and compac...

Abstract

The invention discloses an anti-shear structure of a ductile iron pipe joint and a setting method thereof, relates to the technical field of pipes, and solves the problem that the gap between the pipes is relatively large and the shear resistance is poor. The protruding section on one side and the connecting section that is arranged on the other side of the pipeline and threadedly connected with the protruding section, the two sides of the bottom of the pipeline are also provided with a support frame for supporting it, and the support frame is opposite to the side wall of the pipeline. Butting, the bottom of the support frame is hollow, and the bottom of the support frame is pierced with a positioning column extending into the soil below the pipeline, and the upper end of the positioning column penetrates to the bottom of the support frame to position the support frame. The invention can improve the shearing resistance of the pipeline.

Description

technical field [0001] The invention relates to the technical field of pipelines, in particular to a ductile iron pipe interface shear structure and a setting method thereof. Background technique [0002] Ductile iron pipes refer to the pipes that are casted by high-speed centrifugal casting of centrifugal ductile iron machines after casting molten iron above No. 18 with the addition of nodularizers. They are referred to as ball pipes, ductile iron pipes, and ductile cast iron pipes. used in various fields. [0003] The overall structural strength of the ductile iron pipe is relatively strong, but its interface needs to be connected by a connecting piece. For example, the Chinese utility model with the authorized announcement number CN204829030U discloses a municipal pipeline connecting piece, including a connecting pipe, which is installed at the upper end of the connecting pipe. A first pipeline, a fixing plate is installed on the upper end of the first pipeline, first ex...
