The invention relates to the field of pipe jacking construction, in particular to a pipe jacking working well unearthed simple lifting frame which comprises a back shore frame which is built on one side of a working well and comprises a back shore plane used for lifting the elevation, at least four stand columns installed on the back shore plane and cross beams installed between every two adjacent stand columns. The guide rail frame is erected on the cross beam, the front end of the guide rail frame extends to the position above the working well, the foremost end of the guide rail frame does not cross the axis of the working well, and a lowering space for a jacking pipe is reserved between the foremost end of the guide rail frame and the other side of the working well; the traction assembly comprises an electric hoist connected to the guide rail frame in a sliding mode, an automatic hook claw installed at the end of a steel wire rope of the electric hoist and a driving piece for driving the electric hoist to move; and the anchoring traction piece is used for keeping the balance of the guide rail frame and comprises a counterweight piece arranged behind the guide rail frame and a traction rope connected between the counterweight piece and the guide rail frame. The method has the effects that the engineering cost of pipe jacking working well unearthing is reduced, and the labor investment is reduced.
本申请涉及顶管施工的领域,尤其是涉及—种顶管工作井出土简易起吊架,其包括顶撑架,搭建在工作井的一侧,包括用于抬升标高的顶撑平面、安装在顶撑平面上的至少四根立柱以及安装在相邻两根立柱之间的横梁;导轨架,搭设于横梁上,导轨架前端伸至工作井上方,导轨架的最前端不越过工作井的轴线,导轨架的最前端与工作井另一侧之间保留顶管的下放空间;牵拉组件,包括滑动连接在导轨架上的电葫芦、安装在电葫芦钢丝绳端部的自动钩爪以及驱动电葫芦移动的驱动件;锚固牵拉件,用于保持导轨架的平衡,包括设置在导轨架后方的配重件以及连接在配重件以及导轨架之间的牵拉绳。本申请具有减少顶管工作井出土的工程成本,减少劳动力的投入的效果。
