Jacking and disassembling method for Bailey support under bridge
The invention discloses an under-bridge bailey support jacking and disassembling method. The method comprises the following steps that S1, three suspended traction ships are connected into a ship body through cross beam I-shaped steel; s2, the two bailey beams form a group and are longitudinally assembled to cross beam I-shaped steel of the pontoon, and multiple layers are vertically erected till the dismounting height of the steel box beam bailey support is reached; s3, top cross beams are arranged on the upper portions of the bailey beams, jacks are welded to the upper portions of the top cross beams, and distribution beam frames are arranged on the upper portions of the jacks; s4, water is injected into a water separation bin of the ship body; s5, starting the traction ship in the middle, driving the three traction ships to the bottom of the steel box girder bailey bracket, and slowly erecting the steel box girder bailey bracket; s7, the traction ship is started, and the steel box girder bailey supports are transported to the position of a temporary assembly site on the shore in a floating mode; and S8, hoisting the bailey beam group ashore by using a 500t floating crane, and splitting and hoisting away the bailey beam group in an assembly site. The construction method is safe and reliable, high in construction speed and extremely high in generalization performance.
本发明公开一种桥下贝雷支架顶升拆卸方法，包括如下步骤：S1、将三艘悬浮的牵引船通过横梁工字钢连接成船体；S2、将2片贝雷梁形成一组在纵向拼装至浮船的横梁工字钢上，并竖向搭设多层至达到钢箱梁贝雷支架的拆卸高度；S3、在贝雷梁上部设置顶部横梁，顶部横梁的上方焊接千斤顶，千斤顶上部装置分配梁架；S4、往船体的隔水仓内注水；S5、将中间的牵引船启动，将三艘牵引船行驶至钢箱梁贝雷支架底部，缓慢将钢箱梁贝雷支架架起；S7、启动牵引船，将钢箱梁贝雷支架浮运至岸边临时拼装场地位置；S8、用500t浮吊将贝雷梁组吊装上岸，在拼装场地拆分吊走，本发明安全可靠，施工速度快，有极强的推广性。
