Description

Technical Field

[0002] The integrated pipeline corridor is a box culvert tunnel built underground in the city to accommodate two or more types of municipal pipelines. It can include urban engineering pipelines such as water supply, natural gas, heat, electricity, and communications, and realize the unity of planning, construction, and management. It is an important infrastructure and "lifeline" to ensure the operation of the city. Traditional urban underground pipelines are laid in the shallow space of the road. The increase in pipeline capacity not only causes the phenomenon of "zipper road", but also leads to frequent pipeline accidents, resulting in multiple excavations of the road surface, which not only increases maintenance costs, but also greatly affects the safe operation of the city.

[0003] Promoting the construction of comprehensive underground urban pipeline corridors, coordinating the planning, construction and management of various municipal pipelines, and solving problems such as repeated road excavation, dense overhead line networks, and frequent pipeline accidents will be beneficial to ensuring urban safety, improving urban functions, beautifying urban landscapes, promoting intensive and efficient urban development and transformation, improving the comprehensive carrying capacity of cities and the quality of urbanization development, increasing effective investment in public products, stimulating social capital investment, and creating new impetus for economic development.

During the assembly and construction of the pipe gallery, not only is it necessary to use a large corridor erection machine for hoisting operations, resulting in high equipment use costs, but also after the pipe gallery segment is hoisted into the foundation pit by the corridor erection machine, it is necessary to use other equipment to adjust the posture of the pipe gallery segment, resulting in low efficiency in the assembly and construction of the pipe gallery segment, so a double-span corridor feeding device and a corridor feeding method are needed.
