Abstract
Description
Technical Field
[0001] The present application relates to the technical field of pipeline connection, and in particular to an underground pipeline connection structure. Background Art
[0002] The pipe network top-pull construction technology based on the finite element optimization design of socket-type pipes is an innovative method that combines finite element optimization design and top-pull construction technology. Its purpose is to achieve the optimal layout of the pipeline structure through finite element analysis and optimization design, and to pull the pipeline vertically from underground to the ground through the top-pull construction technology, which includes underground and ground pipeline laying. When laying underground pipelines, it is necessary to connect and support the pipeline joints.
[0003] For example, an underground pipeline connection structure disclosed in Chinese patent announcement number (CN218564715U) includes a foundation pit, a partition, an adjustment structure, a fixed structure, a pipeline shell and a supporting structure. The foundation pit is excavated on the ground at the connection point of the pipeline shell. Two groups of partitions are arranged inside the foundation pit. A group of adjustment structures are arranged on the upper surface of each group of partitions. A group of fixed structures are arranged on the opposite side of each group of adjustment structures. A connecting pipe is arranged between the two groups of fixed structures. A group of flanges are arranged at both ends of the connecting pipe. The utility model is provided with a supporting structure. When it is necessary to adjust the height of the pipeline shell, the operator rotates the rotating block. The rotation of the rotating block drives the rotation of the screw. The rotation of the screw causes the screw to rise and fall inside the threaded pipe. The lifting of the screw drives the lifting plate to rise and fall, thereby adjusting the height of the pipeline shell, thereby facilitating the adjustment of the flatness of the pipeline shell, and avoiding cracks at the pipeline connection when the angle at the pipeline shell connection is too large, causing leakage of the pipeline shell.
[0004] However, as in the above-mentioned patent, there is still a problem of poor connection and anchoring effect for underground pipelines. When the underground pipeline is connected and supported, one side of the connecting mechanism needs to be connected to the pipeline, and the other side needs to be anchored underground to improve the stability of the pipeline connection and avoid leakage of pipeline media. After being connected to the pipeline in the above-mentioned patent, the anchoring performance of its connection structure and the underground space is poor, and its connection is easy to detach or loosen.
