Downward dismantling device and method for continuous beam bridge
The invention discloses a descending type dismantling device for a continuous beam bridge. The descending type dismantling device comprises a static pressure suspension support and a bridge deck crane. The static pressure hanging support comprises a support body, a jack and a hanging rod, the support body is detachably installed on a beam section adjacent to a to-be-cut beam section, the jack is installed on the support body, the hanging rod is connected with a piston rod of the jack, the hanging rod is detachably connected with the to-be-cut beam section, and the jack pre-lifts the to-be-cut beam section through the hanging rod. And the potential energy of the impact load is absorbed when the to-be-cut beam section is cut off. The bridge deck crane is installed on the continuous beam bridge, a lifting appliance of the bridge deck crane is detachably connected with a beam section to be cut, and after the beam section to be cut is cut, the dismantled beam section is lowered to the position below the bridge. The invention further discloses a descending type dismantling method for the continuous beam bridge. According to the descending type dismantling device and method for the continuous beam bridge, the impact load of the beam section cannot influence the deck crane, and the safety in the dismantling process of the continuous beam bridge is guaranteed.
本发明公开了一种连续梁桥下行式拆除装置，包括静压悬挂支架及桥面吊机。静压悬挂支架包括支架主体、千斤顶及吊杆，支架主体可拆卸地安装于与待切割梁段相邻的梁段上，千斤顶安装于支架主体上，吊杆与千斤顶的活塞杆连接，吊杆与待切割梁段可拆卸连接，千斤顶经吊杆预提升待切割梁段，并在待切割梁段切断时吸收冲击载荷的势能。桥面吊机安装于连续梁桥上，桥面吊机的吊具与待切割梁段可拆卸连接，并在待切割梁段切割完成后，将拆除的梁段下放到桥下。本发明还公开了一种连续梁桥下行式拆除方法。上述连续梁桥下行式拆除装置及方法，梁段的冲击载荷不会对桥面吊机产生影响，保证连续梁桥拆除过程中的安全。
