Example Embodiment

[0026] figure 1 The main structure of an underwater drilling apparatus according to the present invention for forming a hole in a bed of a body of water is shown in . The service platform 30 comprises a base body 20 on which is fixed a plurality of support rods 22 on which are arranged support feet 24 for positioning on a bed of a body of water such as a lake, sea or river. To form the hole, the service platform 30 is lowered onto the bed of a lake, sea or river, and then placed with the support feet 24 on the bed of the lake, sea or river. The support feet 24 or upright feet are designed to be adjustable in order to compensate for unevenness in the bed of a lake, sea or river, thereby allowing the service platform 30 to be placed in the desired drilling position.

[0027] In the middle of the base body 20 there is a groove 32 into which the conduit is inserted. The conduit 40 is mounted to be rotational and axially movable relative to the base body 20 . In order to rotate ...

Abstract

The present invention relates to an underwater drilling arrangement and a method for making a bore in a bed of a lake, sea or a river. The underwater drilling arrangement is provided with the following components: a service platform which can be laid down for positioning on the bed of the lake, the sea or the river; a guide tube which is equipped so that the guide tube can rotate and perform axial movement and is fixed on the service platform; a drill rod with a drill bit, which is configured in the guide tube and can be driven through a drilling driver; and a guide tube driver which is configured on the service platform and is used for inserting the guide tube into the bed of the lake, the sea or the river. For reducing friction between housing surface of the guide tube and soil material of the bed of the lake, the sea or the river when the guide tube is inserted, the guide tube is provided with a sliding supporting component.

Description

technical field [0001] The present invention relates to underwater drilling apparatus and methods for forming holes in a bed of a body or body of water. Background technique [0002] For example, such a drilling rig could be used to produce foundations for offshore wind farms or underwater turbines for tidal power plants. [0003] GB 2469190A discloses a drilling method in which a service platform is first placed on the bed of a body of water such as a lake, sea or river. A conduit with a receiving funnel element is arranged on the service platform. Drilling tools are introduced into the conduit and lowered onto the bed of a lake, sea or river to perform drilling. [0004] Another method is known from EP 23 22 724 A1. In this underwater drilling arrangement, a plurality of sleeve-shaped conduits are arranged on a service platform, in which a tubular foundation element has been arranged. The tubular base element is screwed via a drill driver placed in place, which is loos...
