FIELD: construction.
SUBSTANCE: method includes regulation of a khor in its lower part flowing from the bog and damming of water inflow into the bog with the help of arrangement of a pipe culvert, which is coupled to each other with the help of heads. Several pits are dug on the shore of the mineral part of the bog for the depth of the peat deposit. Drainage pumps are installed into pits with installation of discharge lines via damper wells into the lower part of the creek. Then coffer dams are dug, and water is released from the bog into the pit, and then the pumps are started, and water is pumped into the creek. After surface and partially ground waters have been pumped, and peat has settled, they start digging an open drainage network, coupling it via coffer dams with pits, still pumping water with pumps. At the same time peat reclamation is started from the shore line of the peat bog, and peat is replaced with mineral soil, simultaneously installing perforated wells in deepest areas on the bottom of the former peatbog, and the wells are previously wrapped with geotextile. Drainage pumps are placed into perforated wells, and ground waters are pumped into the lower part of the creek, thus reducing ground waters and creating conditions for final replacement of peat with mineral soil.
EFFECT: reduced time for drainage of peat bogs, provides for possibility to fill a groove after peat reclamation with mineral soil.
