Embodiment Construction
[0029] Fig. 2 is the flow chart of the embodiment of the method for erecting simply supported T-beam bridge of the present invention, and present embodiment is used for erecting double-track railway bridge, specifically comprises the following steps:
[0030] Step 11, preparing multiple ∏-shaped beam units. Assuming that the double-track railway bridge is a bridge with 10-hole beams, 20 ∏-shaped beam units need to be prepared. Firstly, connect two simply-supported T-beam decks and diaphragms horizontally under the bridge, and stretch the prestressed tendons of the diaphragms to form a ∏-shaped beam unit; the specific steps are as follows:
[0031] Under the bridge, place the two simply supported T-beams in accurate alignment according to the size set at the relative position during erection;
[0032] Bind the connecting steel bars of the diaphragm at the corresponding positions of the two simply supported T-beams and the connecting steel bars of the bridge deck, and connect th...
