Embodiment Construction

[0040] From Figures 1a to 1e The first filling tube 10 according to the invention is seen in partial section and oblique view. The first filling tube 10 according to the invention has a tube body 12 which has an oval tube cross-section. In the upper end region of the tubular body 12 there is provided a funnel region 14 which widens conically upwards and has an oval receiving section. Funnel region 14 is used to receive and fill fill material to form a column of fill material. Specifically, the fill material is a pourable medium such as sand, gravel, lime, concrete, and the like.

[0041] At the lower end of the tubular body 12 a closing means 20 with two closing flaps 22 is arranged. The closing flaps 22 are each coupled to the tubular body 12 via a pivot joint 26 . The pivot joints 26 each have a joint pin 28 aligned transversely with respect to the pipe axis and about which a respective shell-shaped closure flap 22 is pivotable.

[0042] In the central region of the lo...

Abstract

The invention relates to a filling tube for producing a column of filling material in the ground with a tube body, at the lower end of which a closing means with pivotably linked closing flaps is arranged, which, on introduction of the filling tube into the ground, assume a closed position, in which the tube body is closed in the downward direction and the closing flaps form a penetrating tip, and, on withdrawal of the filling tube from the ground, assume an open position, wherein the tube body is open in the downward direction and filling material can be fed from the tube body into the ground in order to form the column of filling material. According to the invention provision is made in that the closing means has at least one support element which is arranged in a central region at a lower end of the tube body and in that in the closed position the closing flaps rest against the support element. Furthermore, according to the invention provision is made in that the closing means has three or more closing flaps which are arranged so as to be distributed around the circumference of a lower edge of the tube body.

Description

technical field [0001] According to the preambles of claims 1 and 5, the invention relates to a filling pipe for producing a column of filling material in the ground with a pipe body at the lower end of which a closing means is arranged, the closing means With a pivotally coupled closing flap, the closing means, for introducing the filling tube into the ground, assumes a closed position in which the tube body is closed in the downward direction and the closing flap forms a penetrating tip, and in the closed position When the pipe body is withdrawn from the ground, it assumes an open position in which the pipe body is opened in a downward direction and filling material can be fed from the pipe body into the ground so as to form a column of filling material. [0002] According to the preamble of claim 12, the invention also relates to a device for creating a column of filling material in the ground by means of: a rod along which the filling pipe can be moved in a substantially v...
