Pipe jacking device and pipe jacking construction process
The invention relates to the technical field of pipe jacking construction and especially relates to a pipe jacking device and a pipe jacking construction process. The device comprises a conical ejector head arranged at one end of a pipeline, and a hollow cylinder matched with the pipeline is arranged in the pipeline; a limiting piece for relatively fixing or separating the hollow cylinder and thepipeline is arranged between the hollow cylinder and the pipeline; two ends of the hollow cylinder are flush with the two ends of the pipeline; a connector is arranged at one end, away from the ejector head, of the hollow cylinder, and an inner diameter of the connector is the same with that of the hollow cylinder and an outer diameter is smaller than that of the hollow cylinder; and a threaded groove matched with the connector is arranged in one end of the hollow cylinder, and a driving assembly for driving the hollow cylinder and the pipeline to move along an axis direction of the hollow cylinder and the pipeline is arranged at one end, away from the ejector head, of the pipeline. Effects of reducing a workload of groove excavation, saving time and a labor and reducing a possibility of environmental pollution are achieved.
本发明涉及顶管施工技术领域，尤其是涉及一种顶管装置及顶管施工工艺，包括设置在管道一端的锥形的顶头，管道内部设置有与管道相适配的空心筒，空心筒与管道之间设置用于使两者相对固定或者分离的限位件，空心筒的两端与管道的两端相平齐，空心筒远离顶头的一端设置有内径与空心筒相同、外径小于空心筒外径的连接头，空心筒的一端开设有与连接头相适配的螺纹槽，管道远离顶头的一端设置有带动空心筒以及管道沿自身轴线方向移动的驱动组件，达到了减少沟槽开挖的工作量，节省时间与人力，降低对环境造成污染的可能性的效果。
