More Information
Summary:The utility model discloses a string data expands body stock with water expansion ring, including spiral drill tip, variable diameter steel pipe, tail end steel pipe and water expansion ring, the string data expands body stock foremost for the spiral drill tip, spiral drill tip, variable diameter steel pipe and tail end steel pipe connect gradually through the screw, the water expansion ring overlaps to be established on the variable diameter steel pipe, and behind the stock anchor income foundation ditch soil body, the water expansion ring is met water inflation formation expansion section and is provided anchor power. The utility model discloses creatively has solved in soft soil area's deep basal pit engineering in introducing water expansion rubber technique enlarged footing anchoringtechnology, and high -pressure injection expands body stock and has that the pore -forming is difficult, anchor section grouting segment compressive strength not enough, a series of problems of construction quality controllab
