Description
Technical field
Railway formula culvert construction technical field is worn the present invention relates under, and in particular to a kind of rectangular cross section underpass wall
Structure, a kind of rectangular cross section underpass reinforcing bar laying method.
Background technique
Existing Business Line railway mainly has the sleeper being laid on ballast, the rail being mounted on sleeper to constitute.Business Line
Railway is also equipped with track circuit, when track is in occupied state, is in two interorbital circuits of track occupied block
Short-circuit condition shows red band on console;When track is in free state, two interorbital circuits are in breaking shape
State, console upper rail occupy lamp and extinguish;When track circuit loses to orbit occupancy status detection function, the area console Shang Gai
Section display white light band.Based on this, station controllers will be seen that orbit occupancy information by console.
Under wear the difficult point of railway formula culvert construction and be: the reinforcing bar binding space of limited space, especially top of conduit has
Limit, is not easy to the binding of reinforcing bar;May influence the operation of Business Line, such as influence equipment, circuit etc..
In order to avoid culvert top rebars without support it is sagging, in the prior art using concrete lining trolley in place after,
After adjusting the absolute altitude of concrete trolley, center, roof steel bar is installed above concrete trolley, this further limits culvert
The reinforcing bar at top binds space.According to statistics, binding one group of roof steel bar needs 3.5 days, and concrete curing to intensity reaches
After 100%, lining trolley can just be demoulded, and need 3.5 days, this wastes a large amount of time.In addition, in the corner of culvert
Reinforcing bar bind space it is smaller, need to by adding reinforcing bar reinforcement, at this moment may touch top track circuit, formed track not by
Vehicle occupies but shows the situation of red band.
