The multi pipe chemical injection equipment for grouting

摘要

The present invention separates the fastener (A + B1) discharge port and the finisher (A + B2) discharge port up and down so that the quickener is positioned at the top, and the finalizer is positioned at the bottom and injected at the same time, thereby simultaneously injecting the finish and the role of the quickener. The purpose of the present invention is to provide a grouting multi-injection liquid injection device capable of sufficiently achieving the effects of the compound injection by preventing the deviation of the injection purpose as a material.;The present invention has an outer tube, each of which has an internal thread formed on the inner circumferential surface of one end, an injection tube assembly having a fastening material conveying tube and a finalizing material conveying tube in the inner side of the outer tube, and rotatably coupled to the inner circumferential surface of the outer tube; A swivel having a lower part of the assembly and comprising a pipe connection coupling screwed to the outer pipe; An upper coupling screwed to the pipe coupling coupling of the swivel, a grouting rod having female threads formed at both ends of the inner surface to be screwed to the lower portion of the upper coupling, and inserted into the grouting rod, An injection tube assembly having a final material transfer tube and a tube connection coupling screwed to a lower portion of the grouting rod; An upper coupling screwed to the tube coupling coupling of the connecting pipe, an insertion material mixing portion inserted into the upper coupling and having a quick feed material pipe and a final feed material pipe, and screwed to the upper coupling Characterized in that it consists of a lower coupling, a mixing tube mounted inside the lower coupling in close contact with the lower surface of the injection material mixing portion, and a grouting rod screwed to the lower portion of the lower coupling.
