METHOD FOR PRODUCING AN IN-SITU CONCRETE RAMMING PILE AND DEVICE FOR SAME

摘要

The invention relates to a method for producing a Ortbetonverdrängungspfahls in a building (11), comprising the steps of: providing a shell side closed Vortreibrohres (1; 21) with an end outlet (4; 24) for discharging fresh concrete (15) (in the subsoil 11), said outlet (4; 24) an outlet opening (6) with an opposite an inner tube diameter (D ₂₎ of the Vortreibrohrs (1) reduced Auslassöffnungsdurchmesser (D _3), creating a borehole (12) by introducing the Vortreibrohres ( 1; 21) (in the building 11) by means Kopframmung until reaching a defined Bohrlochendtiefe, (13) where the outlet opening (6) is closed, filling the Vortreibrohres (1; 21) with fresh concrete (15), opening the outlet opening (6 ), raising the Vortreibrohres (1; 21) by a defined length (a), wherein fresh concrete (15) from the outlet opening (6) into the borehole (12) flows out, and retracting the Vortreibrohres (1; 21 ) Emanated in the (already in the borehole 12) fresh concrete (15) to form a spread the pile base (16) of Ortbetonverdrängungspfahls. Furthermore, the invention relates to a device for performing the method for producing a Ortbetonverdrängungspfahls in the building (11).
