Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of grouting pipe cleaning, in particular to a shield synchronous grouting pipe dredging device. Background Technique
[0002] The shield synchronous grouting pipe is an important part in shield construction, and is used to inject slurry into the shield tail gap while the shield machine is advancing. This process is crucial for ensuring the stability of the tunnel structure and reducing stratum disturbance. The reason is that when the shield machine advances forward, the shield segments are installed at the tail of the shield machine to form a tunnel lining, and a gap will form between the segments and the excavation face. In order to fill this gap and provide support, slurry needs to be injected through the grouting pipe. Thus, it can prevent the settlement caused by the gap generated by the advancement of the shield machine in the stratum, provide immediate support, and maintain the stability of the tunnel.
[0003] In the existing grouting device, the grouting pipe is prone to solidification of the cement slurry remaining in the grouting hole due to the intermittent use of the grouting device, which in turn leads to a reduction in the slurry spraying volume of the grouting hole or even blockage and inability to grout. Therefore, it is necessary to dredge the grouting pipe. The existing dredging method mainly uses high-pressure water for flushing. However, due to the relatively high hardness of some mud lumps, simple water pressure impact often cannot break and remove them, and tools need to be inserted into the grouting pipe for impact, and then high-pressure water flushing is repeated. This process is repeated until it is completely dredged. The entire dredging process is laborious and time-consuming, prolonging the duration of the grouting project. Content of the Utility Model
