Excavation-free removing device for waste pipeline and construction method
The invention discloses a waste pipeline excavation-free pulling device and a construction method, a vibration device and a grouting pipeline are installed on an electric trolley, before pipe pulling, the electric trolley provided with the vibration device vibrates back and forth in the waste pipeline so as to reduce the compactness of soil around the waste pipeline and facilitate pipe pulling operation, and before grouting is conducted, the grouting pipeline is pulled out through the vibration device. The air bag is inflated so that the air bag can abut against the inner wall of the waste pipeline, the air bag seals the gap between the grouting pipeline and the waste pipeline, and concrete is prevented from flowing back into the waste pipeline during grouting. And grouting is carried out while the pipe is pulled out, vacant sites left when the waste pipeline is pulled out can be filled in time, and concrete is rapidly solidified after flowing out of the end opening of the grouting pipeline, so that ground subsidence is reduced. According to the construction method, the underground pipeline can be efficiently pulled out, pipe pulling, grouting and other procedures are completed at a time, and the construction method has the advantages of being high in safety, high in efficiency and the like.
本发明公开了一种废弃管道免开挖拔除装置及施工方法，在电动小车上安装振动装置和注浆管道，在拔管前，利用安装有振动装置的电动小车在废弃管道中来回振动，以降低废弃管道周围土体的密实度，便于拔管操作，在进行注浆之前，对气囊进行充气使得气囊与废弃管道的内壁相抵，气囊封住注浆管道与废弃管道的间隙处，防止注浆时混凝土回流到废弃管道内。在拔管是同时进行注浆，可以对废弃管道被拔出时的所留下来的空位进行及时填充，混凝土流出注浆管道端口后迅速凝固，以减小地面沉降。此施工方法能够高效地完成地下管道的拔除工作，并且拔管、注浆等工序一次性完成，具有安全性高、效率高等优点。
