The invention provides an assembly type recyclable pipe jacking working well. The assembly type recyclable pipe jacking working well comprises a circular working well main body, wherein the circular working well main body comprises a concrete blade foot assembly and a plurality of steel side wall assemblies which are stacked on the concrete blade foot assembly layer by layer from bottom to top; each steel side wall assembly is formed by splicing a plurality of steel side wall units through bolts in the circumferential direction; and the concrete blade foot assembly is formed by splicing a plurality of concrete blade foot units through door-shaped ribs in the circumferential direction. The construction process of the assembly type recyclable pipe jacking working well is assembly from bottomto top. Compared with the prior art, the assembly type recyclable pipe jacking working well has the beneficial effects that the assembly degree is high; the unit adaptability is high, the pipe jacking hole opening position in the well is flexible, the connecting mode is simple, the soil body supporting effect is good, and the safety is easier to guarantee; the resource utilization rate is high, and after construction is finished, all the steel side wall units can be recycled; and after temporary recycling of construction, the soil body in a working area is recovered as much as possible, and the underground environment is protected.
本发明提供了一种装配式可回收顶管工作井，包括圆形工作井主体，圆形工作井主体包括混凝土刃脚组件和多个自下而上逐层叠放在混凝土刃脚组件上的钢侧壁组件，钢侧壁组件由多个钢侧壁单元沿圆周向方向通过螺栓拼接而成，混凝土刃脚组件由多个混凝土刃脚单元沿圆周向方向通过门形筋拼接而成，本发明的施工工艺为自下而上装配。与现有技术相比，本发明的有益效果在于：装配化程度高；单元适应性程度高，井内顶管开孔位置灵活，连接方式简单，土体支护效果好，安全性更容易保证；资源利用率高，施工结束后，可以收回全部钢侧壁单元；该施工的临时回收后，使得工作区域内的土体尽可能恢复，保护地下环境。
