A new type of anti-seepage, enclosure structure and construction method

The invention discloses a new type of anti-seepage and enclosure structure and construction method, which aims to overcome the shortcomings of the anti-seepage and enclosure structure of foundation pits and shafts in the prior art, and provide no need for special construction machinery or large construction machinery , The construction site is small, the construction period is short, the investment is low, no open excavation is required, and it can provide a new type of anti-seepage and retaining structure for the shaft or foundation pit. The structure includes a connection beam, a flower tubeand an impermeable body, the flower tube is arranged around the outside of the excavation area, the connection beam is connected to the top of each flower tube, and an opening is provided along the tube body of the flower tube; An impermeable body formed by the pressure grouting in the flower tube is arranged around the flower tube, so that the cement slurry under pressure diffuses from the opening and penetrates into th
