Demolition construction method for bridge superstructure
The invention discloses a demolition construction method for a bridge superstructure. The demolition construction method mainly comprises the steps of demolition preparation, construction safety enclosure, demolition of a bridge deck crash barrier, demolition of a bridge deck, demolition of a beam plate and site clearing, wherein the demolition of the beam plate comprises main span full-suspendedbeam demolition operation and semi-suspended beam and T beam demolition operation; and the main span full-suspended beam demolition operation and the semi-suspended beam and T beam demolition operation each comprise the steps of removing longitudinal and transverse connection, taking a beam, lowering the beam and transporting the beam. The demolition construction method is basically opposite to the installation process of a bridge, and is convenient to master and implement; and under the conditions that the construction boundary is limited and mechanical equipment and construction conditions do not exist, the construction method is adopted for solving the problem of integral demolition of a beam body, is small in operation influence, ensures the construction safety, and has certain popularization significance.
本发明公开一种桥梁上部构造的拆除施工方法，主要包括拆除准备、施工安全围护、桥面防撞栏拆除、桥面拆除、梁板拆除和场地清理的步骤；其中所述梁板拆除又包括主跨全挂梁拆除作业和半挂梁及T梁拆除作业；所述主跨全挂梁拆除作业和所述半挂梁及T梁拆除作业均包括解除纵、横向联系、取梁、落梁和运梁的步骤；本拆除施工方法基本与桥梁的安装流程相逆，便于掌握和实施；在施工界限受限、机械设备、施工条件不具备情况下，采用本施工方法解决梁体整体拆除，既对运营影响较小，又保证了施工安全，具有一定推广意义。
