Grouting device and grouting construction method

According to the grouting device and the grouting construction method, in order to meet the requirement of a large-area grouting project and overcome the defects of an existing grouting technology, grout is directly conveyed to grouting points through the grouting main pipe and the grouting branch pipes, and according to grouting amount data collected by the flow sensors of all the points in real time, the grouting amount is calculated according to the grouting amount data; and the grouting pressure is adjusted through the grouting pressure regulator, so that on-demand grouting of a large-area component is realized. The grouting main pipe is connected with the multiple grouting branch pipes, grouting can be conducted on the multiple grouting stations at the same time, and construction benefits are improved; flow sensors arranged on the grouting branch pipes can timely know the grouting amount of each position; according to data of the flow sensor, ordered grouting is achieved by adjusting the grouting pressur
