Reinforcing method of pipe joint when suspending socket type pipe

Abstract

A pipe joint reinforcement method for suspending socket-type pipes, the method includes the following steps: 1) Excavating earthwork; 2) Prepare a steel pipe, and operate the steel pipe; 3) Clean the outer wall of the pipeline to be suspended; 4) Place Steel pipe; 5) Fill the gap between the steel pipe and the pipeline to be suspended; 6) Use the steel pipe that has been opened to buckle the pipeline to be suspended; 7) Weld the upper and lower parts of the steel pipe wrapped on the pipeline to be suspended; 8) Grout into the steel pipe through the grouting hole on the steel pipe with holes, so as to fill the gap between the steel pipe with holes and the pipeline to be suspended; 9) The grouting material in the steel pipe with holes and the steel pipe with no holes Carry out maintenance; 10) After the maintenance is completed, suspend the pipelines to be suspended. The method of the present invention uses the support of the steel pipe to make the pipe joint and the pipeline form an integral body, and at the same time, by filling the gap between the steel pipe and the pipeline, the slippage of the pipeline in the steel pipe is avoided. The whole method has compact steps and is easy to construct. .

Description

technical field [0001] The invention belongs to the technical field of socket-type pipe suspension, and in particular relates to a method for reinforcing pipe joints when a socket-type pipe is suspended. Background technique [0002] During the construction of foundation pit or foundation trench, underground pipes often pass through the foundation pit and affect the construction. For steel pipes or PE pipes with better integrity, suspension methods are generally used to solve them. [0003] For the socket type interface, the diameter of the pipe head at the socket end is larger than the diameter of the pipe, and the interface is a large pipe in the middle and small on both sides. The interface is generally densely packed with rubber rings or asphalt wadding. [0004] When this type of interface is suspended, due to the uneven force on each suspension point, the interface is prone to large deformation and leakage, and even causes the joint to fall off directly. In order to s...

Problems solved by technology

[0006] Regardless of whether the above two methods are pipe replacement, suspension or relocation, the original pipeline needs to be shut down. After the original pipeline is shut down, the pipeline will not be able to transport the medium, which will affect the operation of the property rights unit and the use of users.

[0007] In addition, no matter whether the above two methods are pipe replacement, suspension or relocation, new pipes and joints are required during construction, which increases additional costs and construction time, and greatly reduces construction efficiency.
