A specially adapted device for the continuous laying of heat conduction tubes in the bottom sediment of lakes and other bodies of water features a floating and driveable work platform (1) on the water surface, which by means of a controllable support device (6, 8) carries at least one guiding wheel for hose (3) extending down into the bottom sediment. In order to produce a version of this device specially designed for small scale application, it is proposed that the work platform of the invention be comprised of a pontoon-equipped raft (1), which by means of a land-anchored winching device can be directed along a desired tube-laying path while steering with the help of the steering mechanism, especially a guiding line (10) stretched over the water surface, and that the controllable support device includes a block (8) working the support beam (6) that carries the guiding wheel for hose (3) in order to drive the wheel (3) to the desired depth in the bottom sediment. The wheel (3) is mounted so that it can rotate freely and with the radially positioned tubing control mechanism (11), which is designed to grip into the bottom sediment during the raft's (1) propulsion and thereby incite the guiding wheel for hose (3) to rotate.<IMAGE> |
