[0002] A pipe gallery, that is, a corridor for pipelines, is a building structure for centrally laying large-scale device pipelines. A pipe gallery is a steel or reinforced concrete structure used to support pipelines laid above or underground. Most pipe galleries are in the shape of "open", and are composed of columns, cross beams and trusses made of steel structure or reinforced concrete structure. It is the main place for centralized laying of large-scale device pipelines, and there are above-ground pipe galleries and underground pipe galleries. Above-ground pipe galleries are commonly seen in chemical and related factories, where pipelines are concentrated together, arranged along the outside of the device or plant, and supported by brackets; underground pipe galleries are mostly used in urban underground, such as urban utility tunnels, where municipal public pipelines such as electricity, communication, and water supply are centrally laid in a single structure.

[0003] For example, the underground pipe gallery protection structure with the publication number CN205134385U includes two opposite soil-cement mixing pile walls, and the soil-cement mixing pile walls are formed by connecting a number of soil-cement mixing piles radially to each other. An underground pipe gallery accommodation cavity is formed between the two soil-cement mixing pile walls.
