[0028] Reference Figures 1 to 10An integrated prefabricated trestle bridge includes: several tripods 5 mounted on side walls 6; two rows of tracks 1 mounted above the tripods 5; a walkway truss 2 mounted above the two rows of tracks 1; and railings 3 mounted at the front and rear ends of the walkway truss 2. The two rows of tracks 1 are symmetrically arranged, and each track 1 is composed of several sets of rails connected in series. The tracks 1 are detachably connected to the tripods 5, the walkway truss 2, and the railings 3, forming a stable overall structure in which the tracks 1, walkway truss 2, and railings 3 are interconnected. In this embodiment, the span between adjacent tripods 5 should not exceed 1.5m. The bottom of the tripod 5 should be flush against the wall to prevent insufficient slenderness ratio of the anchor bolts.

[0029] Please refer to Figure 4 and Figure 5 Preferably, in this embodiment, the main body of the rail is made of square steel. One end of the rail is equipped with a plug 11, and both sides of the rail near the front and rear ends are provided with connection holes 12. Several first lifting lugs 13 and several second lifting lugs 14 are provided on one side of the rail, flush with the top of the rail. Several third lifting lugs 15 are provided on one side of the rail, flush with the bottom of the rail. The number of first lifting lugs 13, second lifting lugs 14, and third lifting lugs 15 can be increased or decreased according to specific construction adjustments.
