This invention of a multi-point pouring construction method of ground modification and the devices thereof is to pour ground-modifying material into soft ground in various points, providing the most proper way of pouring for each layer simultaneously or selectively especially for ground with various layers as well as providing three-dimensional ways of pouring vertically and horizontally. Also, it is able to control at random and pour material in via multiple pipes at the same time in order to shorten pouring time and promote reliability of permeation pouring into grits. Methods mentioned above is to embed poring pipes 8 with outlets 7 into multiple pouring points 6 of ground 1 to pouring into ground-modifying material through outlets 7 motored via independent motive sources 4 with multi-jointed pouring devices 5 of multiple pumps 3, 3...3 controlled by a central controlling device 26. And guiding pipes are connected to multiple pouring pipes 8 via ducts to pouring ground-modifying material from multiple outlets into multiple pouring points 6, 6...6 on ground. |
