双液高压化学注浆工艺，是将水泥等4种材料按一定比例配制成注浆液，通过双液高压注浆泵和自制手摇泵压入壁外周围松散介质中，将松散流动的介质固结成一胶化体，从而形成可靠的止水端幕。它操作方便，在流砂层动水中堵水率达95％以上，防渗漏达100％。1工艺特点（1）可在动水 Two-fluid high-pressure chemical grouting process is to mix cement and other four kinds of materials into a grouting liquid according to a certain proportion, and presses a double-liquid high-pressure injection pump and a homemade hand pump into a loose medium around the wall to loosely flow the medium. Consolidate into a gel body to form a reliable water end curtain. It is easy to operate, and the water plugging rate in flowing water layer is more than 95%, and the leakage is 100%. 1 process features (1) can move water
