CONSTRUCTION METHOD OF SEMI-INTEGRAL ABUTMENT BRIDGE USING STEEL BOX GIRDER

摘要

PURPOSE: A construction method of a half integrated abutment bridge using a steel box girder is provided to supplement a limitation on an application and integrate an abutment and an upper structure. CONSTITUTION: A banking task of an abutment section is performed and a pile(120) is constructed. A lean concrete(130) of an alternating foundation is applied and a pile head is reinforced. A spread foundation(210) is constructed and an abutment(220) is constructed by pouring concrete an alternating sphere and a wing wall. A bridge bearing(230) is set up. A backfilling task is performed in the alternating rear side. A first support slab(710) and a second support slab(780) are constructed. An approach slab(750), a shock-absorbing slab(760) and a main track packing section(770) are successively constructed. An expansion/contraction control apparatus(810) is set up between the approach slab and the shock-absorbing slab. A bridge deck is packed in an asphalt or a LMC(Latex Modified Concrete).
