Modern society develops and progresses faster and faster, municipal infrastructure construction of cities is more and more complete, underground space resources of cities are more and more narrow, and space resources are more and more valuable. In most cities in China, various pipelines are basically laid in a traditional direct-buried mode, the direct-buried pipeline is convenient to construct, the service life is short, various different types of pipelines are laid in a mess, a large amount of underground space is occupied, the pipelines are often crossed with basic construction projects of the cities, and the phenomenon that the laid pipelines are damaged occurs. Once the directly-buried laying pipeline is damaged, the pipeline needs to be checked and repaired by slotting and breaking the way, so that traffic jam can be caused, inconvenience is brought to normal travel of citizens, the surrounding environment is polluted, and the city appearance of a city is influenced. In order to overcome the defects of the traditional direct-buried laying pipeline and fully and reasonably utilize underground space resources, underground pipe gallery engineering construction is vigorously developed in China in recent years.
At present, underground concrete pipe gallery structures such as municipal pipe galleries, underground passages and the like generally adopt the forms of integral cast-in-place or segmental prefabrication and on-site splicing. Although the prefabricated pipe gallery can be prefabricated quickly and shortens the construction period, the length of the segment limited by the hoisting weight is short, so that more joints and poor waterproof performance are caused, the buried line is not suitable for large height difference and large corner change, and the design concept and specification of the related prefabricated pipe gallery are not fully mature; the pipe gallery is integrally cast on site, and has good waterproof and anti-seismic performance, can adapt to complex structural section forms, and is widely applied due to relatively mature relevant design specifications, construction technologies and processes. But traditional pipe gallery structural style makes cast-in-place template braced system comparatively complicated, and installation, dismantlement template are inefficient, and traditional cast-in-place construction techniques adopts the manual work to independently accomplish each process of cast-in-place in narrow and small cabin in addition, has seriously reduced cast-in-place pipe gallery's efficiency of construction, causes the construction process of pipe gallery slow, consequently seems to be more important to pipe gallery structural style, the relevant research and development of quick construction technique.
