CA 02942790 2016-09-14 1 2 ABSTRACT Pile foundations for power transmission towers or the like are installed in different types of soil prone to frost heaving. The pile foundations provide bearing capacity against horizontal loads, reduce labor content and installation cost, and increase reliability against the impact of frost heaving forces of the soil on the pile. The pile foundation has a casing pipe and a dipped pile, comprising a shaft and a toe bulb, secured at the bottom of the shaft. The pile comprises rigid elements that are mounted on the shaft in the direction of horizontal forces acting on the pile against the anticipated horizontal loads. The rigid elements transfer horizontal forces from the pile to the casing pipe.

The invention relates to the construction of pipelines in difficult geological conditions. The present method involves positioning and rigidly fastening a coil of a pipeline support on two support axles in the form of beams which are transversely arranged and movably mounted in frames of the support. Lifting jacks are positioned under each support axle and the coil is raised or lowered, together with the support axles, to a planned height, ensuring that the angle of inclination of the coil corresponds to the planned value. Then, the achieved planned position is fixed by means of fastening the support axles in the frames. The ends of the support coil are welded to a pipeline. Adjusting the height position when using the stationary support involves loosening the fastening of the support axles in the frames of the support. Then, lifting jacks are positioned below each support axis, and the coil is raised or lowered to a planned height, maintaining a calculated angle of inclination of the coil. The achieved planned position is fixed with the help of adjustment plates.

The sections are provided with hermetically-sealing damping inserts made of foamed rubber (foam rubber), which provide for the hermetic seal of the duct during the repeated assembly and disassembly thereof, and with a lock mechanism. The thermally-insulating cladding is comprised of units (segments) made of foamed glass (foam glass), which are secured to the inside surface of the protective cover by means of a bitumen-based adhesive. A coating is applied to the surface of the foam glass units that comes into contact with the gate valve in order to protect the units against abrasion.

The invention relates to foundation engineering and can be used for installing drill-inserted pipeline supports and power transmission line supports, and also in installing buildings and structures on permafrost soil. The aim of the invention consists in developing a pile-installation process which makes it possible to prevent soil slurry and groundwater from entering a bore-hole during the summer installation of drill-inserted piles in permafrost soil in the presence of water-laden soil in the seasonal freezing and thawing layer, and also in preventing the possible effect of frost heaving forces arising from heaving deformations in seasonal freezing conditions. The present method involves driving a casing pipe to the depth of the seasonal freezing and thawing of the soil, drilling a pilot hole to a depth of no less than the standard depth of the freezing of the soil, pouring in a hardening material in an amount necessary to fill the cavities between the pilot hole and the piles from the bottom of the pilot hole to the bottom of the level of the seasonal freezing and thawing layer of the soil, inserting the piles, and filling the empty space between a pile and the casing pipe using a non-heaving inert particulate material.

The invention relates to the anti-fire insulation and thermal insulation of pipes, and specifically to methods for installing anti-fire insulation and thermal insulation on welded joints of pipes intended for transporting petroleum and petroleum products. A method for installing thermal insulation on the welded joints of pipes which are to be laid above-ground involves protecting a welded pipe joint against corrosion by means of a heat-shrinking polymer tape, installing thermally-insulating foam-glass shells over the joint, said shells being connected by means of tightening bands with locks, adhering a heat-melting adhesive tape to the edges of a protective pipe casing, said tape overlapping onto the foam-glass shells, and installing a protective galvanized metal casing symmetrically relative to the center of the welding joint. The technical result consists in providing for the corrosion protection and thermal insulation of a welded joint of steel pipelines, and the proposed method improves the process of installing thermal insulation on a pipeline, thus reducing the cost of installation and decreasing labor-intensity.

The claimed invention relates to the field of above-ground pipeline construction and can be used in the organization of pipeline supports in difficult geological conditions, such as in conditions of permafrost. The technical result achieved by using the claimed invention consists in providing for the stability of a structure and in redistributing loads from a pipeline to a pile foundation. The aim is achieved in that a stationary pipeline support includes a coil which is mounted, by means of electrically-insulating assemblies, onto four stands which are height-adjustable so that the height and incline of the support can be adjusted, and which are secured on a single-level grillage foundation which rigidly rests on a pile foundation. The coil is in the form of a pipe which is provided with an outer casing and with a layer of thermal insulation; the pipe has an inner tubular shell affixed at the central portion thereof; longitudinal ribs are rigidly affixed to the shell, thus allowing the coil to be secured to the stands; the stands are secured to the grillage foundation by means of support flanges. The load-bearing structure of the coil, and the principle behind and way in which the coil rests on the stands, make it possible to prevent axial and lateral displacement of a pipeline, and permit transfer of a load born by the coil to the grillage foundation of the support by means of brackets with electrical insulation, with adjustable stands and a pile foundation.

The invention relates to construction, and specifically to welding above-ground and below-ground pipelines from high-strength pipes with controllable heat input. Use of the invention will increase the bearing capacity of pipelines manufactured using pipes, pipe sections and pipe strings which have been welded to form a joint. The present method involves connecting two or more cylindrical metal pipes, pipe sections, and pipe strings by means of a welded annular joint, and using arc welding along the entire perimeter of the pipe, wherein the criterion for producing a high-quality weld joint involves the optimal selection of parameters of a thermal welding cycle. The proposed welding method allows for providing an optimal structure, high durability characteristics and viscoplastic characteristics in the area of the weld joint, and for providing for the required bearing capacity of a pipeline and for the operational reliability thereof.

The invention relates to pipe heat insulation and in particular to methods of heat insulation installation on welded joints of subterranean pipes for transporting oil and oil products. The method includes applying an anticorrosive layer on the welded joint using heat-shrinkable polymeric tape, mounting heat insulating polyurethane foam pipe coverings on the tape, using tie straps with locks to secure the pipe coverings, gluing hot-melt adhesive tape at the edges of a pipe protective envelope to overlap the envelope and the pipe coverings, installing a metal casing symmetrically relative to the center of the weld joint, and sealing the metal casing and the envelope with a heat- shrinkable polymeric fabric. The technical result provides anticorrosive protection and heat insulation of the welded joint of steel pipelines, provides improved heat insulation installation on the pipeline, and reduces the cost of installation and labor intensity.
