Method and device for the subsequent treatment of dumps for the protection of the environment

摘要

In a method and a device for the subsequent treatment of dumps, old waste tips or the like for the protection of the environment, above all of the ground water, from stored noxious substances and poisons, the ground surface 2 of the dump is divided up into planar sections 3 which are located directly next to one another. At their junction points 4, pilot bores 5 are executed as a controlled target bore from the starting shafts 6a to the target shafts lying respectively opposite. Guide elements 7 whose start and end are located in the starting shafts 6a or target shafts lying opposite are inserted into the pilot bores 5. In the annular space between the guide elements 7 and the walls of the pilot bores 5, a clearing and injection device 8 is introduced which loosens up the floor of the planar sections 3 with a clearing element 8c (chain or cable) and prepares for the treatment with the sealing agent 9. The clearing and injection device 8 is guided at the junction from the planar section 3 into the pilot bore 5 via the deflection element 13, which is accommodated in a deflection housing 14. The deflection housing 14 is clamped tight in a barrier liquid by means of the hydromechanical clamping clip 15 on the guide element 7 of the pilot bore 5 or is set to a predetermined sliding speed. The advance and the forward and backward movement of the clearing and injection device 8 take place as a result of corresponding actuation of the two...via the target shafts or via ...
