Description
Изобретение относитс к электрохимической защите стальных свай от коррозии в морской воде в зоне периодического смачивани выше ватерлинии.This invention relates to the electrochemical protection of steel piles against corrosion in seawater in the zone of periodic wetting above the waterline.
Обычно дл защиты свай от коррозии в зоне полного погружени их в морской воде успещно используетс катодна и протекторна защиты . В зоне периодического смачивани сваи защищаютс лакокрасочными покрыти ми с дополнительным усилением защиты пущсмазкой .Usually, cathode and sacrificial protection are used to protect the piles from corrosion in the zone of their total immersion in seawater. In the zone of periodic wetting, the piles are protected with paint and varnish coatings with an additional enhancement of the protection of lubricants.
Недостатком защиты лакокрасочными покрыти ми вл етс быстра изнащиваемость нокрытий и трудность ремонта свай в услови х эксплуатации морских эстакад.The disadvantage of paintwork protection is the rapid weariness of coatings and the difficulty of repairing piles under operating conditions of offshore ramps.
По предлагаемому снособу этот недостаток устранен применением разъемной анодной рубащки, надеваемой на защищаемый участок сваи, наход щийс в зоне периодического смачивани выще ватерлинии , и выполн ющей роль катодной защиты.According to the proposed procedure, this disadvantage is eliminated by using a detachable anodic jacket that is worn on the protected portion of the pile, located in the zone of periodic wetting of the waterline, and performing the role of cathodic protection.
Анодна рубашка представл ет собой полосы листового железа, соединенные внизу железным хомутом, а вверху - специальной воронкой дл непрерывного или периодического орошени рубашки морской водой , в которой наход тс сваи морской эстакады.The anodic jacket is a strip of sheet iron, joined at the bottom with an iron yoke, and at the top, a special funnel for continuous or periodic irrigation of the shirt with seawater, in which the piers of the sea trestle are located.
С целью уменьшени расхода воды на смачивание рубащки и равномерного орошени защищаемого участка водой, последний обматывают слоем ткани (мещковины), хорошо удерживающей влагу и способствующей образованию солевого осадка легко впитывающего влагу и работающего как электролит.In order to reduce water consumption for wetting of the cutter and uniform irrigation of the protected area with water, the latter is wrapped with a layer of cloth (meshchinka), which retains moisture well and contributes to the formation of salt sludge that absorbs moisture and acts as an electrolyte.
При подключении тока установленной мощности дл электрохимической защиты катодно-пол ризуема поверхность металла не подвергаетс разрущению, и таким образом обеспечиваетс длительна эксплуатаци свай морских эстакад.When a current of installed power is connected for electrochemical protection, the cathode-polarized metal surface is not subject to destruction, and thus long-term operation of the piers of offshore racks is ensured.
