Section jacking method final joint steel support locking device
The invention relates to a locking device for a final joint steel support by a jacking segmental method, which comprises locking cross beam assemblies symmetrically welded on the front side and the rear side of a connecting steel support, two groups of bracket assemblies arranged on a positioning sleeve bottom plate and two groups of limiting assemblies arranged on the positioning sleeve bottom plate, the two support assemblies are symmetrically arranged on the front side and the rear side of the thrust steel support, the two limiting assemblies are symmetrically arranged on the front side and the rear side of the connecting steel support, and the opposite-pull screw locking assembly is installed between the locking cross beam assembly and the support assemblies. The connecting steel support and the thrust steel support are locked through the opposite-pull screws and the nuts, the thrust steel support is prevented from rebounding due to the fact that the thrust steel support bears too large water pressure, the posture stability is guaranteed, the connecting steel support can be limited, and it is guaranteed that the pushing direction of the connecting steel support is more accurate.
本发明是一种顶进节段法最终接头钢支撑锁定装置，包括对称焊接在连接钢支撑前后两侧的锁定横梁组件、设置在定位套筒底板上的两组支架组件以及设置在定位套筒底板上的两组限位组件，两组支架组件对称设置在止推钢支撑的前后两侧，两组限位组件对称设置在连接钢支撑的前后两侧，锁定横梁组件、支架组件之间安装有对拉螺杆锁定组件。本发明通过对拉螺杆和螺母对连接钢支撑、止推钢支撑进行锁定，防止止推钢支撑承受水压力过大发生回弹，确保姿态稳定，还可以对连接钢支撑进行限位，保证其顶推的方向更加准确。
