Horizontal filter well producing method, involves sinking substantially pump shaft, and introducing filter pipes into protective pipes, where protective pipes are removed and filter pipes are connected to shaft

摘要

The method involves sinking a pump shaft (1), and sinking several vertical ground bores (2) adjacent to the shaft. Ground bores are filled with filter gravel (4). Protective pipes are horizontally introduced into the filter gravel, and filter pipes are introduced into the protective pipes. The protective pipes are removed and the filter pipes are connected to the shaft. Protective pipes are inserted through pressing without flushing fluid. An independent claim is also included for a horizontal filter well with a pump shaft.
