Gripping device comprises bearing structure for discharge pipe fitted at an angle to vertical by means of adjusting installation angle of discharge pipe. Method of assembling discharge pipe from discharge pipe sections from vessel is performed by means of vessel, equipped with gripping device, which comprises bearing structure for discharge pipe fitted at an angle to vertical by means of adjusting installation angle of discharge pipe, wherein first section of discharge pipe is lowered into bearing structure by a lifting device, second section of discharge pipe is lowered onto first section of discharge pipe by lifting device and first and second sections of discharge pipe are connected to each other.EFFECT: invention also relates to a method of laying rockfill at a given site at bottom of a water body, performed by said device for laying rockfill; providing accuracy of installation in required position of lower surface of discharge pipe, eliminating risk of damage of structure when laying rockfill.18 cl, 11 dwg

ethod for construction of the cluster site housing of initial water separation // 2596777
FIELD: oil and gas industry.SUBSTANCE: invention relates to equipment for oil industry. Cluster site of the wells is selected, after that the place for construction of the cluster site housing of initial water separation is selected, flow rates of the cluster site development wells and physical-chemical properties of extracted products are measured. Amount of water to be reset on the cluster site, required pump diameter and depth, and a number of bore pits are measured, rotary drilling is performed with direct flushing of clay solution under the conductor. Drilled out rock is collected, is lowered, the conductor made of the tubes is fixed and cementing of annular space is performed, perform rotary drilling with direct flushing of clay solution under the production string, casing pipe is lowered and fixed, cementing of casing pipe string annulus is performed. On the upper part of the casing pipe an adapter is mounted, production trees are installed on inner string and tubular insert, production tree is mounted and hydraulic tests of bore hole at pressure are performed.EFFECT: invention enables to increase efficiency of the cluster site.3 cl, 2 dwg

Equipment for levelling of underwater bed // 2520117
FIELD: process engineering.SUBSTANCE: invention relates to equipment for underwater bed levelling and can be used for protection of light reflectors at the bar at cable sagging. Equipment for levelling the stone filling make the underwater bed consists of bar 2, weight 1 secured thereat, light reflectors 5 arranged at bar top outer circle, and cable 4. Levelling of underwater bed is performed by lifting the bar 2 with weight 1 on cable 4 and lowering them by gravity. Detection of levelled surface location is performed by parameters of beam reflected from reflectors 5 to light receiver. Protective structure is mounted at said equipment to protect collision of said light reflectors against said sagging cable 4. Besides, there is the zone for beams transmission to point aligned with beam part reflected from light reflectors to light receiver.EFFECT: ruled out collision between sagged cable and light reflectors.5 cl, 7 dwg

ethod to prepare base before laying of concrete mix in winter conditions // 2495195
FIELD: construction.SUBSTANCE: method for preparation of a base before laying of a concrete mix behind forms in winter conditions includes cleaning of the base from garbage, dirt, ice and snow. In the lower part of the forms of the base section previously selected for cleaning, in its opposite ends one hole is arranged for supply of hot air, for this purpose a nozzle is installed at the angle of 7-30 to the base, and the end of the nozzle is flattened to form a pneumatic monitor, contaminating elements are removed with a suction pipeline installed in the hole arranged in the opposite end of the forms. Supply and suction of air is carried out with one unit along a cycle partially closed through the forms, the sucked garbage is caught with a container.EFFECT: increased water impermeability, strength, durability of coupled elements of previously laid hardened concrete and freshly laid concrete.2 cl, 3 dwg
Quick-hardening bound cement mortar, method for preparation thereof, and method for repairing concrete and reinforced concrete underwater structures // 2248951
FIELD: manufacture of building materials.SUBSTANCE: quick-hardening bound cement mortar including, vol parts: cement 6-9, water 2-3, aqueous epoxide resin dispersion 1, and hardener 1, said cement being of quick-hardening type and said dispersion additionally containing polyurethane rubber. Quick-hardening cement can be alumina-based cement. In a method of preparing quick-hardening bound cement mortar including mixing cement with aqueous epoxide resin dispersion and hardener on a surface immediately before underwater application, one volume part of water is diluted with one volume part of hardener and stirred, after which one volume part of aqueous dispersion of epoxide resin and polyurethane rubber are added, resulting mixture is agitated and then, depending on particular application, 1 or 2 vol volumes of water are added and, after agitation, resulting composition is used to temper quick-hardening cement, and stirred in low-speed mixer until soft plasticine-type plastic homogenous mass is obtained, after which mortar is held up to 5 min and agitated once more. Escort method of repairing concrete and reinforced concrete underwater structures comprises conveying quick-hardening cement mortar into underwater repair operation zone and manually laying thus prepared mortar onto prepared surface with defective spots. Conveyance of mortar can be accomplished by means of containers or buckets, or yet by means of worm mortar pumps. Invention enables preparation of repair material characterized by dimensional stability, short setting time and fast hardness development, non-diffuseness in aqueous media, waterproofness, frost resistance, crack resistance, resistance to corrosive media (salt and alkali solutions, petroleum products), high adhesion to cement, concrete, and metallic surfaces, and not leading to corrosion of hardware.EFFECT: improved performance characteristics of cement mortar.6 cl
