The invention discloses a laterally spliced combination
T beam bridge with wavy steel webs. The laterally spliced combination
T beam bridge comprises a plurality of prefabricated
T beam units (1) and cross beams 5, wherein a porous continuous combination T beam is formed through the longitudinal connection of adjacent prefabricated T beam units by the cross beams 5, and the lower end surfaces of top slab wet joints (2) of two adjacent prefabricated T beam units are connected with top slab lower edge
steel plates (2-1). The invention further discloses a construction method of the laterally spliced combination T
beam bridge. The construction method comprises the following construction steps: constructing bridge piers, bridge
abutment pier bodies (6) and bridge
abutment cap beams (4), erecting trestles (3) at the outer sides of the bridge piers, and installing the prefabricated T beam units at the trestles; fixing the top slab lower edge
steel plates (2-1) to which studs are connected at the parts of the top slab wet joints of two adjacent prefabricated T beam units, and using the top slab lower edge
steel plates as support formworks to pour top slab wet joint concrete (2-3); longitudinally pouring
pier top cross beams or installing prefabricated
pier top cross beams (5) on the trestles, and connecting all spans of prefabricated T beam units into the porous continuous T beam. The use quantity of the trestles and the formworks is effectively reduced, the cost is reduced, traffic on roads below the bridge is not interrupted in the construction process, and the scenery requirement of the urban bridge is met.
