In order to address the current lack of reference materials for the design of thermal pipeline support piers in comprehensive pipe galleries, this article attempts to establish a scientific and standardized design method, providing theoretical basis and practical guidance for the design of supports. The article adopts a combination of theoretical analysis and engineering examples to first explain the constraint function characteristics of support piers on thermal pipelines, and based on mechanical principles, conduct force analysis on three types of thermal pipeline support piers in the pipe gallery to clarify the load transfer mechanism. Subsequently, based on the design specifications for concrete structures, the support piers of the DN600 thermal pipeline in the pipe gallery are designed. Combined with their structural form and cross-sectional strength calculations, a complete engineering example is formed through a standardized process. The calculation results indicate that the pipeline support piers design method based on the concrete structure design specifications is feasible and can provide reference for the standardized design research of thermal pipeline piers in comprehensive pipe galleries.
