The invention discloses grooving wall protection slurry for a sand-gravel stratum underground diaphragm wall. The grooving wall protection slurry comprises the following components: water, clay, caustic soda, guar gum and modified starch. The content of the clay is 15-20% of the mass of the water; the content of caustic soda is 0.1-0.3% of the mass of water; the content of the guar gum is 0.3-0.5 per mill of the mass of the water; the content of the modified starch is 0.3-0.5 per mill of the weight of the water; the raw materials for preparing the slurry are convenient to obtain, the preparation process is simple and rapid, and the requirement for workers is low; the main raw material natural clay of the slurry formula is low in cost, the engineering benefit can be well improved, and the engineering cost is reduced; the slurry wall protection effect is good, the performance is stable, and the application range is wide; and the formula materials of the slurry are environment-friendly and low in pollution. 本发明公
