The disclosure relates to the construction of a support for above-ground pipelines and can be used for laying pipelines in in permafrost and on slopes. The result of the support is uniform distribution of the load from the pipeline to a bedding cradle, displacement of a movable part in response to predetermined conditions, and prevention of deformation due to soil heaving. The result is achieved due to inclusion of moving and fixed parts. The movable part includes a semi-cylindrical cradle with two semi-annular frames on the outside of the cradle, detachable half-yokes fix the pipe in the cradle, side cheeks welded to the frame and movably fixed to the tower base by a hinged joint, and a base slidably positioned on a stationary surface of the support. The objective is also solved using a support assembly being structurally different than prior art supports, as described herein.

The invention relates to thermal engineering construction, particularly to individual seasonal cooling devices, or temperature stabilizers of soils. The solution is aimed to expand temperature ranges at which temperature stabilizers can be installed and to prevent debris from sealing materials from entering into the well cavity having a coolant. The device contains a temperature stabilizer that functions as a two-phase thermal siphon and includes an aboveground condensing part and underground transporting and vaporizing parts. The temperature stabilizer is placed into the well along with coolant. The well is a hollow cylindrical body with a bottom and a capping element at a top end. The capping element includes a hole for receiving of the temperature stabilizer. The capping element is a detachable stuffing-box seal that includes a support ring installed on a round step in the well, a pressure ring, and thermally expanded graphite rings pressed therebetween.

A pile for being driven into soil includes a shaft and a frost sleeve (upheaval resistant sleeve) surrounding the shaft. The frost sleeve (upheaval resistant sleeve) is located on the shaft between a top of the soil and a frost line. The pile further includes a grout disruption (separation) plate. The grout disruption (separation) plate is located at the frost line.

Embodiments of the present disclosure provide a frost-heave-resistant pile foundation support device including a pile foundation cylinder, a pile foundation cylinder top seat, a pile foundation cylinder base, and a frost heave penetration mechanism, wherein a top of the pile foundation cylinder is fixedly installed with the pile foundation cylinder top seat, and the pile foundation cylinder top seat is configured to connect to a target to be support; the pile foundation cylinder base is disposed at a bottom of the pile foundation cylinder, and a plurality of threaded drill rod assemblies are provided on the pile foundation cylinder; the frost heave penetration mechanism is fixedly installed on a cylindrical wall of the pile foundation cylinder. When soil undergoes frost heave action, a horizontal anchor rod of the frost heave penetration mechanism can penetrate laterally outward into the soil, so that the pile foundation cylinder is anchored to the surrounding soil, which serves as a frost-heave-resistant effect.
