Embodiment Construction

[0030] exist Figure 1a In , the initial stages in the implementation of the drilling method according to the invention are shown. First, the only partly shown drill pipe 5 is introduced in a manner known per se using a guiding device into the softer soil 2 , which in the illustrated embodiment is located below the body of water 3 . The drill pipe 5 protrudes upwards and beyond the surface of the body of water 3 so that the receiving part 20 can be attached to the upper region of the drill pipe 5 in a rotationally fixed manner. In the illustrated embodiment, the platform 30 is additionally fastened detachably in the upper region of the drill pipe 5 .

[0031] As part of the drilling rig 10 according to the invention, the drilling arrangement 100 is lowered in the direction of the receiving part 20 by means of a telescopic rod 130 held by a lifting cable 62 on the lifting device 60 . In this example, the lifting device 60 comprises a tracked vehicle with a hanger arranged on ...

Abstract

The invention relates to a drilling device and a drilling method for drilling inside a casing tube with a drilling apparatus, which has a supporting frame with a fastening means for fixation with respect to the casing tube and a drilling tool, which is driven in a rotating manner via a telescopic rod by means of a drill drive arranged on the supporting frame. At the upper end of the casing tube a receiving part is arranged in accordance with the invention, onto which the supporting frame can be fastened. The receiving part is adjustably supported between a drilling position and an offset position, in which the receiving part is laterally offset with respect to the casing tube.

Description

technical field [0001] The invention relates to a drilling rig with a drilling device for drilling in a casing tube, the drilling device having a support frame with fastening means for fixing relative to the casing tube, and a drilling tool, The drilling tool is driven in rotation by means of a drilling drive arranged on the support frame via a telescopic rod. [0002] The invention also relates to a drilling method for producing a borehole in a drill pipe, wherein the support frame of the drilling device is fixed relative to the drill pipe, and the drilling tool is driven by means of a telescopic rod to Rotary motion is driven whereby soil material is removed inside the drill pipe. Background technique [0003] A drilling rig and a drilling method of this type are known from EP1154078B1. In order to produce drilled piles in soft ground, the drill pipe is first driven or screwed in by means of known guiding devices. In order to remove the soil material inside the drill pi...
