Abstract
Description
Technical Field
[0001] The invention belongs to the field of pipe gallery engineering, and in particular relates to a design and construction method of an underground pipe gallery capable of resisting uneven settlement. Background Art
[0002] With the development of the times and the advancement of science and technology, the integrated pipe gallery has become an important part of urban construction and belongs to underground infrastructure. The integrated pipe gallery refers to the integrated corridor of underground urban pipelines, that is, the structure built underground in the city to accommodate Class 2 and above urban pipelines. It is an important infrastructure to ensure the operation of the city. With the vigorous promotion and development across the country in recent years, the integrated pipe gallery has been widely used and promoted. In the construction of the integrated pipe gallery, when the bottom surface of the structural foundation is located in the soft soil layer, its foundation soil is usually difficult to meet the bearing capacity requirements of the structure, so it will cause uneven settlement of the soil under the pipe gallery, and then increase the height difference between the pipeline section in the main building and the pipeline section of the pipe gallery. Excessive settlement difference caused by the pipeline will damage the traditional pipeline, causing the pipeline to deform or seriously damage.
[0003] The settlement of the pipe gallery on the soft soil foundation will also increase the settlement difference between the pipe gallery and the main building, causing deformation or damage to the connection between the pipe gallery and the main building. In severe cases, it may cause tensile damage between the pipe gallery and the main structure. In addition, the soil quality of the foundation in different areas may be different, which will cause different settlements of different pipe sections. This uneven settlement will cause settlement differences between different pipe sections, leading to damage between pipe sections. It can be seen that the pipe gallery set up on the soft soil foundation may cause a series of problems such as settlement differences and settlement damage between the pipe gallery and the main building, between pipe sections of the pipe gallery, and between pipelines in different pipe galleries, resulting in a chain reaction, causing structural damage to buildings and structures and unusable pipelines.
[0004] Therefore, developing a combined system that can systematically solve the above-mentioned problems such as the settlement difference between the pipeline corridor and the main building, between the pipeline sections of the pipeline corridor, and the pipelines inside the pipeline corridor is an issue that needs to be urgently solved in the project.
