Local waters purification method for watering of peatlands

FIELD: peat extraction.

SUBSTANCE: invention relates to the extraction of peat, specifically to the work on the restoration of peat bogs, and in particular to the watering of worked-out peatlands. Method consists of using water from an accessible source, its redistribution to distributors throughout the peatland area. Moreover, on the developed peat bog, an artificial relief is created in the form of barrier vertical waterproof fences with the possibility of flowing to the free areas between them. In this case, watertight fences are tied to stakes, that are placed vertically and their lower ends are buried in the soil of the peat bog, while on the area of the worked peat bog the main and distribution polyethylene pipelines are laid on the bottom, they are equipped with distribution wells, in the upper part of which are provided evenly on the sides of the surface with holes for draining the water and provided with a lid, in addition, the incoming first well of the main pipeline is combined with a mobile pumping station in the form of SNP, and the outgoing end portion thereof is connected to a partitioning hydraulic engineering structure, dividing the worked-out laid operational road into an upper and a lower portion, a well in the center of which the bottom is supplied with a discharge vertical pipe, connected by means of a knee at a level difference with a polyethylene main pipeline with distributing pipelines of the second section, while a well with an installed vertical discharge pipe is supplied from above with a lid in the form of an external cylinder with a screw elevator with the possibility of moving the outer cylinder along the height.

EFFECT: technical result is the provision of efficient injection of local waters into the main and distribution pipelines with wells-dampers, ensuring controllability and flexibility of the system for flooding the developed peatlands to resume marshes to its original state and improve the ecological situation.

SUBSTANCE: method includes orientation of a flexible concrete mat (FCM) in respect to a bottom surface by its one or another side depending on type of soil. The method to install the FCM according to the first version includes orientation of FCM to the bottom surface with the side having higher penetration power as water flow in a water course exceeds the value of non-washing speed for this section of the water course and/or if characteristics of bottom surface soil are sufficient for FCM self-submersion into soil under gravity. Otherwise the FCM is oriented to the bottom surface with the side having the lower penetration power. The method of FCM installation according to the second version in case, if the bottom surface is formed mainly by rock, half-rock or clayey soils includes FCM orientation to the bottom surface with a side, on which blocks have bases of flat shape and larger area in plan compared to the opposite side. If the bottom surface is formed mainly by sandy or macrofragmental soils, then orientation of FCM to the bottom surface is carried out with a side, on which blocks have bases of smaller area in plan or are made without bases. If the bottom surface of the water course mainly contains sludges, sapropels, peated soils or peats, then the FCM is oriented to the bottom surface with its any side. The flexible concrete mat comprises concrete blocks, connected to each other row by row and in rows with at least one connection element. Surfaces in these blocks at the upper and lower side of the FCM are made mainly narrowing in direction from the central part of the blocks. The bases of the blocks have flat shape at one or both sides of the FCM. Ratios of average values of the base area, height of blocks and angles of inclination of the side surface of blocks must correspond to the laws given in the patent claim. The coefficient of asymmetry between FCM sides exceeds or its equal to 1.05.

EFFECT: higher reliability of FCM adhesion to protected bottom surfaces of any type.
