Device for sand backfilling of one or more cables or pipes during ploughing into the ground by means of a cable laying plough

摘要

The invention relates to a device for sand backfilling of one or more cables or pipes during ploughing into the ground by means of a cable laying plough which has a vibrating blade with a cable guiding channel (which opens into an outlet opening pointing towards the rear) and a sand chamber. The device is characterised in that the sound chamber (11), which is connected to the blade (7) for vibration, has at least one flat or smooth boundary surface, which runs obliquely or vertically upwards, and its lower opening (14) is located behind and above the outlet opening (10) of the cable guiding channel (9).
