Description

TECHNICAL FIELD

[0001] The utility model relates to concrete prefabricated pipe gallery technical field, especially a pipe gallery prefabricated component. BACKGROUND

[0002] As the carrier of urban underground comprehensive pipelines, the pipe gallery is widely used in the fields of municipal infrastructure such as power, communication, water supply and drainage, and gas. The traditional pipe gallery construction mostly adopts the cast-in-situ concrete method, which has problems such as long construction period, great difficulty in quality control, and serious environmental pollution. The prefabricated pipe gallery gradually becomes the mainstream direction of pipe gallery construction due to its advantages such as high construction efficiency, controllable quality, and good environmental performance.

[0003] In the design and manufacturing process of the pipe gallery prefabricated component, the inner corner part of the component is a key area. Due to the significant stress concentration phenomenon at the inner corner, cracks or deformations are easily generated in the transportation, hoisting and use process, which affects the overall structural safety and durability of the pipe gallery. The traditional pipe gallery prefabricated component inner corner reinforcing method mainly includes increasing the steel bar density, setting reinforcing ribs, or using angle steels. However, increasing the steel bar density or setting reinforcing ribs will increase the manufacturing difficulty of the prefabricated component. The traditional reinforcement increases the self-weight of the component, which increases the transportation and hoisting difficulty. The rigid reinforcing materials such as angle steels may form new stress concentration points at the inner corner, which intensifies the local cracking risk, still affects the overall structural safety and durability of the pipe gallery, and affects the service life of the pipe gallery.
