Box girder dismantling process
The invention provides a box girder demolition process. The box girder demolition process comprises the following steps that a bridge is cut section by section in the bridge direction to form multiple demolition sections; the demolition section in the safe demolition area is cut section by section in the direction perpendicular to the bridge direction, so that the demolition section is divided into a plurality of beam pieces; the multiple beam pieces in the same dismantling section are divided into at least two beam piece sets, supports are arranged at the two ends of each beam piece set respectively, and the multiple beam pieces in the same beam piece set are fixed into a whole through the supports; a lifting appliance is connected to the support so that the two beam piece sets can be moved to a collecting area in sequence; and blasting demolition is conducted on the demolition section outside the safe demolition area. According to the box girder dismantling process, the dismantling section is divided into the multiple girder pieces, the multiple girder pieces are divided into the two girder piece sets through the two sets of supports, the supports are connected with the lifting appliance, the beam piece sets are lifted by the lifting appliance in two times, the multiple girder pieces are transferred in two times, and the dismantling efficiency of a bridge is greatly improved.
本发明提供了一种箱梁拆除工艺，包括以下步骤：将将桥梁沿桥向进行逐段切割形成多段拆除段；对安全拆除区域内的所述拆除段沿垂直于桥向的方向进行逐段切割，以将所述拆除段分成多个梁片；将同一个所述拆除段中的多个所述梁片分为至少两个梁片组，每个所述梁片组的两端分别设有支架，所述支架将同一所述梁片组中的多个所述梁片固定成一体；将吊具连接于所述支架，以依次将两个所述梁片组移至收集区；对安全拆除区域外的所述拆除段进行爆破拆除。本发明提供的箱梁拆除工艺，将拆除段分隔成多个梁片，通过两组支架将多个梁片分成两个梁片组，支架与吊具连接，吊具分两次将梁片组吊运，实现将多个梁片分两次转运，大大提高了桥梁的拆卸效率。
