Influence of building settlement factors: During the construction and early use of most high-rise buildings, the foundation will have a certain degree of settlement, which will affect the gas pipeline. However, when the foundation treatment plan of high-rise buildings lacks rationality or problems such as excessive subsidence of the foundation occur, it will cause changes in the gas pipeline laying line and the surrounding environment, and when the degree of change is too large, problems such as gas pipeline rupture and gas leakage will occur. Therefore, in the design of gas pipelines, the influence factors of building settlement on gas pipelines should be fully considered. Influence of pipeline resistance factors: In the middle and upper areas of high-rise buildings, there will be a certain additional pressure in the gas pipeline, and the pressure value will continue to increase with the increase of building layers. For example, in the top floor area of a high-rise building, when the building owner uses gas pipes to ignite and cook, there are generally problems of poor gas supply stability and unstable airflow, and there may be safety hazards such as gas leakage and excessive gas inhalation by the human body. ACCIDENT. When there are too many owners living in the building, the gas pressure value of the gas pipeline will also increase.
Influence of environmental factors: In most urban high-rise buildings in my country, the laying area of gas pipelines is divided into two parts, which are the gas pipelines laid outdoors and the gas pipelines laid indoors. During the use of gas pipelines, the gas pipelines laid outdoors will continue to be disturbed by the influence of the climate environment, resulting in pipeline rupture and gas leakage. For example, in the high-rise buildings distributed in the northern region of my country, the outdoor gas pipelines are affected by the excessive temperature difference in summer and autumn, resulting in thermal expansion and contraction of the pipelines, and there may be pipeline rupture problems. In the southern region of my country, the air humidity is high, and the gas pipeline is continuously corroded by the humid air, which may cause corrosion and damage to the outer structure of the pipeline. In addition, gas pipelines are also affected by various problems such as lightning current strikes, external force collisions, and natural factors, resulting in safety problems such as gas leakage and pipeline rupture. Influence of pipeline self-gravity factor: In high-rise building projects, due to the large number of building layers and high height, the gas pipeline will gradually generate a certain pressure due to the influence of its own weight, and this pressure value will vary with the building layer. The number keeps increasing. When the problem is serious, the surrounding buildings and facilities will be deformed and damaged under the influence of the gas pipeline's own weight, resulting in the rupture of the gas pipeline and gas leakage.
