Grouting pipeline and anti-floating anchor rod construction method using grouting pipeline
The invention provides a grouting pipeline and an anti-floating anchor rod construction method using the grouting pipeline, and the grouting pipeline comprises a grout conveying inner pipe, a grout conveying outer pipe and a grout conveying spray head, the grout conveying inner pipe is fixed in the grout conveying outer pipe through a fixing set, the grout conveying outer pipe and the grout conveying inner pipe are coaxially arranged, a rib body placing channel is formed in the grout conveying inner pipe, and the grout conveying spray head is arranged in the rib body placing channel. The interior of the outer slurry conveying pipe is a slurry conveying channel, the slurry conveying spray head is detachably connected to the end of the outer slurry conveying pipe, and the problems that in the prior art, a rib body (anchor rod) is prone to being squeezed to the hole wall by high-pressure jet cement slurry, and high-pressure jet grouting in the area blocked by the rib body is difficult to spread are solved.
本发明提供了一种灌浆管道及使用该灌浆管道的抗浮锚杆施工方法，灌浆管道，包括：输浆内管、输浆外管以及输浆喷头，输浆内管通过固定组固定在输浆外管内部，且输浆外管与输浆内管同轴设置，输浆内管内部为筋体放置通道，输浆外管内部为输浆通道，输浆喷头可拆卸地连接在输浆外管的端部，解决了现有技术中存在的筋体(锚杆)易被高压喷射水泥浆挤在孔壁处，而被筋体阻挡的区域高压旋喷注浆难以扩散过去的问题。
