The utility model relates to a barricade formula portal crane track girder construction. The technical scheme who adopts is: the symmetry is equipped with drilling retaining pile, makes pile bolck guan liang on the drilling retaining pile, makes barricade formula track girder construction on the pile bolck guanliang, lays the track in the barricade formula track girder construction. Be equipped with screw spike and pinch plate rail fastening, the track passes through screw spike and pinch plate rail fastening fixes in barricade formula track girder construction. The utility model discloses, arrange the track girder construction in drilling retaining pile's top, will erect simultaneously the track girder construction of portal crane within range and widen to 400 -500mm, satisfied orbital width that sets up. This kind of design at first, increases the effective distance between retaining pile and the building, saves construction space, secondly, can avoid the waste that the track roof beam caused as interim structure, it is last, combine barricade and track roof beam can save the time limit for a project together, give security for finish the work on time.
