Background
At present, the width of a platform of a small and medium-sized railway station house in China is usually 9m or 12m, wherein the typical column distance of a canopy of the 9m wide platform in the direction parallel to a track is 9m, the width of the canopy in the direction vertical to the track is 9m, and a cast-in-place reinforced concrete Y-shaped bilateral cantilever canopy is usually adopted. The cast-in-place reinforced concrete Y-shaped single-column canopy with two overhanging sides is widely applied to small and medium railway station houses in China due to the characteristics of reliable structure, economy and durability, but the structural form also exposes the following defects along with the further development of the building industry and the railway industry in China:
1. the construction period is long. The characteristics of the cast-in-place reinforced concrete structure determine the sequence of the construction of the canopy, namely field leveling or backfilling → foundation construction → scaffold erection → template erection, reinforcement binding → concrete pouring → template detachment after the concrete reaches the strength, scaffold → station surface pavement and canopy decoration. The above construction steps can not be implemented in parallel, and one process must be completed before the next process, which undoubtedly brings huge challenges for engineering projects with short construction period.
2. Under the environment condition of open-air operation, the construction quality is greatly influenced by factors such as weather environment and the like, and particularly for northern severe cold areas, great troubles are caused to the construction quality of concrete engineering in cold seasons as long as 3-6 months every year.
3. Environmental pollution, noise pollution and the like caused by a large amount of on-site wet operations in a construction site do not meet the requirements of green building development of energy conservation, land conservation, water conservation, material conservation and environmental protection advocated in China at present.
4. A large amount of field manual work, with the continuous rising of labour cost of our country, will bring the rising of cast in situ concrete canopy structure cost by chance.
