The invention discloses a grouting mechanism and a continuous grouting method for rock mass.The grouting mechanism comprises two grouting pumps, a first grouting pipe and second grouting pipes connected to the output ends of the grouting pumps respectively, and the first grouting pipe is connected with the two second grouting pipes through a three-way pipeline; the three-way pipeline comprises two input ends and an output end, a valve clack assembly is arranged in the three-way pipeline, so that the valve clack assembly is switched between the two input ends, and the valve clack assembly is rotationally connected between the two input ends; the first grouting pipe is connected with the output end of the three-way pipeline, the second grouting pipe is connected with the two input ends of the three-way pipeline, and the end, away from the three-way pipeline, of the first grouting pipe is further connected with a grouting anchor rod. According to the grouting mechanism and the continuous grouting method, continuous grouting can be achieved, the grouting amount is increased, the grouting efficiency is improved, and the tunneling requirement of a current shield tunneling machine is met.
Description
technical field [0001] The invention relates to a shield tunneling grouting process in coal mine excavation, in particular to a grouting mechanism and a continuous grouting method for rock mass. Background technique [0002] With the continuous improvement of productivity, my country's coal production and utilization methods have undergone major changes, from traditional coal mining technology to intelligent, safe, and green mining, and to achieve high-quality development of clean, efficient, and low-carbon utilization. In modern coal mining, coal excavation is particularly important. Therefore, centralized control, remote operation and continuous transportation of auxiliary transportation are implemented for coal excavation and anchoring, so as to realize intelligent, unmanned and less-manned key processes of coal mining. [0003] At present, coal excavation adopts a new operation method of 5.5-meter tubular shield machine excavation, with a daily footage of 20 meters, and ...
