[0002] Water stop curtain is often used in foundation pit engineering to prevent or reduce the seepage of groundwater in the foundation pit to ensure construction safety and prevent house settlement after being put into use. Common water stop curtains include jet grouting pile water stop curtains. Jet grouting pile is a device that uses a drill to drill a jet grouting pipe and a nozzle to a designed elevation at the bottom of the pile, and then uses a high-pressure generating device to make the liquid flow obtain a large amount of energy, which is then sprayed out of the nozzle at high speed to form a liquid flow with a high concentration of energy, which directly destroys the soil. During the spraying process, the drill rod rotates and lifts, causing the slurry to mix with the soil to form a columnar consolidated body with a certain diameter, thereby reinforcing the foundation. During construction, two work processes are generally used, namely, first drilling and then spraying, and then drilling and spraying.
