According to the super-span self-contained pattern prestretching cantilevered structure group of above-described embodiment, by multiple super-span self-contained patterns
Prestretching cantilevered structure unit composition.It is adjacent since weight body is arranged side by side along the vertical direction of the extending direction of main drag-line
More thin bars are mounted between two main rods, the both ends of every thin bar are respectively connected to the side of two adjacent main rods
Face, therefore be connected with each other between each super-span self-contained pattern prestretching cantilevered structure unit, surpass so that formation one is stable
Large span self-contained pattern prestretching cantilevered structure group.
Since weight body is made of armored concrete, weight body can satisfy the overhanging of super-span self-contained pattern prestretching
Force request is answered needed for mechanism use process.
Since main rod is steel pipe, can satisfy that main drag-line forms axial pulling force answers force request.
Since earth anchor is made of armored concrete, earth anchor own wt is larger, thus preferably cooperate with steadying line,
Play the role of stable weight body.
Since main drag-line is cable wire, it can satisfy connection main rod and weight body be formed by the tension of pulling force and want
It asks.
The preferred embodiment of the present invention has been described in detail above.It should be appreciated that the ordinary skill of this field is without wound
The property made labour, which according to the present invention can conceive, makes many modifications and variations.Therefore, all technician in the art
