METHOD FOR COMPLEX MULTILAYER ENGINEERING PROTECTION OF TERRITORY TO BE DEVELOPED AGAINST UNDERFLOODING Russian patent published in 2005 - IPC

FIELD: hydraulic and reclamation building, particularly in permafrost zones.

SUBSTANCE: method involves creating planned embankment on territory to be developed; performing surface water drainage from embankment. Embankment slope provide water flow to water receiving means and drainage of surface water from adjoining areas. Ground water flowing from adjacent areas are drained during and/or after embankment erection and removed from embankment body. Motor roads and in-territory water draining channel systems are used as water receiving and draining means within the boundaries of territory to be developed. Water diversion ditch system is used for water removal from outside the territory to be developed. Water diversion ditch system are formed along embankment perimeter and above slopes reinforced from embankment side. Motor roads are built on embankment top, wherein motor road pavements are located beneath embankment surface. Embankment has slopes directed towards roads. Motor roads have longitudinal and transversal slopes providing surface water flow along roads to water draining channel system, which drains water into water diversion ditch system. Surface water flows into water diversion ditch system from embankment areas located at a distance from motor roads due to inclining above areas towards water diversion ditch system, which directs water to purification system or to natural temporary or permanent water channels. For ground water removal from embankment body drainage layer is placed in embankment so that drainage layer diverts accumulated water to water diversion ditch system, which is also used to remove ground water entering from areas located adjacent territory to be developed.

EFFECT: simplified structure, reduced labor inputs, provision of stable and effective protective system operation.
