Soil-removal-and-replacement stirring method for constructing waterproof curtain
The invention relates to a soil-removal-and-replacement stirring method for constructing a waterproof curtain. The soil-removal-and-replacement stirring method includes the steps that 1, guiding hole pile positions are arranged along the axes of cement mixing piles; 2, steel pile casings are buried, the hole walls are stabilized through mud, and in-hole to-be-excavated soil is taken out through a rotary drilling machine with a wet method; 3, holes are drilled, and the hole walls are stabilized through mud till the guiding holes and backfill operation space meet requirements; 4, the mud in the pile holes is removed through an air lifting mud removing machine, and the pile holes are filled with pile forming soil materials; 5, when the backfill completing distance meets the cement mixing pile continuous working requirement, a mud discharging guide furrow is excavated; 6, a cement mixer is in position, and cement mixing piles are constructed; 7, an unprocessed interlayer part left between every two adjacent guiding hole pile hole positions is forcedly mixed through a mixed machine, and soil-removal-and-replacement construction of the waterproof curtain is completed. The soil-removal-and-replacement stirring method is scientific and reasonable in design, simple in technology and low in construction cost, and is used for deep-foundation-pit waterproof curtain, common construction machines are sufficiently used, the completed waterproof curtain is good in waterproof effect, and construction is safe and reliable.
