1. A method for casing-pile device comprising apparatus well known manner, characterized in that the hole is lowered gunning device by feeding a dry mix and water in the nozzles is their mixing and applying to the surface when the device rotates, then recruit the necessary thickness of concrete, and gunning device is raised up to the design otmetki.2. Gunning apparatus for erecting the wrapper piles, comprising a housing and a nozzle, wherein the nozzle in an amount of four pieces arranged equidistantly in the horizontal and vertical sections, while the gunning unit has a hinged connection via a bearing with a bisexual rod, the inside of which is applied dry mix, and on the external water, the mixture mixing occurs in the nozzles, pressure jet, the mixture is discharged at the borehole surface, thereby advanced rotational force gunning apparatus under koto th nozzle extension occurs when stopping rotation of the nozzle device by springs back to its original position.
