STRUCTURE OF TEMPERATURE COOLING FOR ENGINEERING AND TECHNICAL DESIGN OF EMPILS AND SLOPES IN PERMAFROST REGIONS Russian patent published in 2022 - IPC E02D17/18 

FIELD: thermal cooling structures.

SUBSTANCE: invention relates to a thermal cooling structure for the engineering and technical arrangement of embankments and slopes in permafrost regions. The temperature cooling structure for the engineering and technical arrangement of embankments and slopes in permafrost regions contains a lower layer located on the earth's surface at the foot of the slope in permafrost regions, an inner waterproof layer and an outer waterproof layer that cover the lower layer. The inner waterproof layer is in contact with the soil of the slope in the permafrost areas, the diatomite layer filling the space defined by the inner waterproof layer, the bottom layer and the outer waterproof layer, which are connected to each other, the pebble layer laid on top of the diatomite layer, and the drainage pipe containing the first a segment passing through the outer waterproof layer and entering obliquely into the lower part of the diatomite layer, and a second segment located outside in the air. The drainage pipe consists of a permeable section, which is located in the diatomaceous layer, a non-porous section, passing through the outer waterproof layer and an intercepting section and an expansion section, which are located outside in the air. The water-permeable section is characterized by having one closed end and the other end communicating with the non-porous section, the water-permeable section being provided with a plurality of water-permeable holes evenly distributed and covered by the filter layer on its outer surface. The intercepting segment is a U-shaped segment, one end of which communicates with the non-porous segment, and the other end communicates with the expansion segment, and the end part of the expansion segment is open and located on top of the drainage.

EFFECT: ensuring the reliability of the temperature cooling structure for the engineering and technical arrangement of embankments and slopes in permafrost areas, which is suitable for construction work using heavy construction equipment.
