[0002] The pipe gallery, that is, the corridor of the pipeline, is a place where many pipelines are concentrated together in chemical and related factories, arranged along the outside of the device or factory building, usually in the air, supported by brackets, forming a shape similar to the corridor. In order to fundamentally solve the problem of urban land utilization, the pipe gallery came into being and gradually developed into a mainstream municipal form, which greatly facilitated the maintenance and inspection of municipal facilities, improved the urban land utilization rate, reduced the number of road poles and inspection wells and chambers of various pipelines, and maintained the integrity of the road surface and the durability of various pipelines. With the increase in the number of pipe galleries, the number of support trolleys has also increased, and the support trolley is mainly used for template support during the construction of the pipe gallery, making the construction of the pipe gallery more convenient.
