Adjustable pressure curtain grouting device

Abstract

The application relates to a pressure-adjustable curtain grouting device. The pressure-adjustable curtain grouting device comprises a storage box for slurry stirring, a connecting structure, a slurry pipeline with a switch valve connected to the storage box, a pressure-adjusting pump connected to the slurry pipeline, a jetting pipeline for curtain grouting connected to the pressure-adjusting pump, the jetting pipeline comprising a first pipeline and a second pipeline, one end of the first pipeline being connected to the pressure-adjusting pump, the other end of the first pipeline being in communication with the second pipeline through a connecting structure for adding auxiliary materials into the jetting pipeline, an auxiliary material pipeline with a pump being arranged in communication with one side of the connecting structure, and an auxiliary material mixing box being in communication with the auxiliary material pipeline. The application can timely change the properties or concentration of the currently jetted slurry, timely eliminate the adverse effects of slurry spouting or large slurry consumption, and simultaneously carry out auxiliary material and slurry grouting only by mixing the auxiliary material, so that the construction efficiency is greatly improved.
