Description

Technical Field

[0001] The utility model relates to the technical field of tunnel construction, in particular to a lining trolley capable of casting a supporting beam of an air duct plate. Background Art

[0002] Since the tunnel is a relatively closed space, the fire heats up quickly and the fire temperature is high when a fire occurs, which can easily cause concrete to burst, expose structural steel bars, and damage the tunnel structure. It is necessary to add an air duct structure in the tunnel to prevent the fire from damaging the tunnel. The air duct structure is a support beam set on both sides of the tunnel, and air duct plates are installed on the support beams to divide the tunnel into two parts, upper and lower parts.

[0003] The current construction steps of the air duct plate support beam are often to first cast the secondary lining through a lining trolley, and then reserve steel bars at the position of the support beam during the casting process. After the secondary lining is cast, the lining trolley is used again to cast the support beam at the steel bar position. This method requires two castings, and a gap will appear between the support beam and the secondary lining, which greatly reduces the life of the support beam. In addition, the process of reserving steel bars greatly increases the construction period, requiring a large amount of manpower and material resources. Utility Model Content
