A process for the preparation of a subterranean surfaces of parts of water - and disposal system as well as surfaces of parts of water - and disposal system

摘要

A borehole is drilled down and reamed out at desired depth to give a collection space (13) closed off at both ends and joined to the surface by connecting bores whose inserted pipes (3,4) feed surface water into the space or withdraw water stored in the space. Additional holes drilled out from the space into the adjoining ground are set at a defined height within the space (3) and take seepage pipes (2) whose water can percolate into the adjoining ground. The space is sealed off by running down a pipe (1) closed off at both ends into the space, using plastics seepage or percolating pipes run out 1500 m from the space. The connecting lines (3,4) are drilled horizontally and lined with their pipes, using seals in the lines in the form of valves used to keep out soiled surface water.
