Odessa, 48, BC "Caucasus", office 733, 735 Hydraulic structures Watered soils are not an obstacle to our technologies, thanks to which we can use them in hydraulic engineering. The methods of Geostroy Holding are based on giving additional strength to dams, dams and other hydraulic structures, as well as creating an anti-seepage curtain. If necessary, a special filtration mode can be created, soothing filtration flows at high pressure gradients. An attractive fact is that the formulations of injection solutions, which include cement, bentonite, plasticizers and various additives, as well as their injection systems, are not only theoretically calculated, but have already been used in practice. Water suppression Excessive groundwater has a destructive effect on the foundations of various buildings and structures. In this regard, the suppression of water inflows in such cases is simply a necessary operation. This is especially true for areas with an increased level of atmospheric precipitation, as well as low areas located in zones with tectonic disturbances. Due to the suppression of water inflows, the water cut in the soil is reduced by several tens or hundreds of times, and the engineering structures retain their integrity. What is an anti-seepage curtain? It is arranged in order to prevent the penetration of the filtration flow into the bottom of various structures. This technology is most relevant during the construction of buried underground facilities, hydraulic structures, as well as during the development of pits in flooded and watered soils. In a constructive sense, an anti-seepage curtain is a vertical (sometimes inclined) barrier that is created in the soil along the perimeter of the foundation of the structure. Currently, it represents the most effective protection of the foundations of all kinds of objects from the effects of groundwater. When developing an anti-seepage curtain, the planning decisions of the structure and the hydrogeological properties of the territory must be taken into account. How are anti-seepage curtains arranged? To create curtains, various physical, chemical and construction methods are used, based on the technique of injecting special aggregates into the soil. Injection is carried out through wells drilled in several rows in a checkerboard pattern around the perimeter of the structure. If we are talking about loose soils, then in them an anti-seepage curtain is arranged with the help of bitumization, freezing, silicatization and clay formation. Most often, the depth of the curtain lies in the range from 10 to 50 meters. In some cases, it can reach over 100 meters (for example, when building large-scale hydraulic structures). How are artificial islands arranged? The method of pressure injection grouting also makes it possible to create artificial islands of stability in water areas. Their device is carried out as follows: На основании расчетной схемы инъекторы погружаются в дно на глубину от 4 до 7 метров. Вокруг инъекторов устанавливается съемная металлическая опалубка. В получившееся пространство помещают разнородный грунтовой материал, в том числе крупнообломочный. За уплотнением следует нагнетание цементного раствора вкупе с пластицифирующими упрочняющими добавками (осуществляется поинтервально через инъекторы, начиная с погруженной в дно нижней части). Опалубка при необходимости ее дальнейшего использования извлекается после того, как достигается проектная прочность. На прочность образовавшегося техногенного конгломератного материала, которая может быть весьма высокой, напрямую влияет качество цемента и заполнителя. Также возможно применение технологии создания особо прочного слоя (технология бронирования) в боковой поверхности искусственного острова. В некоторых случаях изготавливается несъемная опалубка. Искусственные острова прочности могут залегать на глубине до 20 метров. По конфигурации они могут быть практически любой формы. Наша компания имеет в своем распоряжении современную проектно-расчетную базу по данной тематике, а также специализированное оборудование и подготовленные кадры. Благодаря всему этому мы способны надежно защищать гидротехнические сооружения от неблагоприятного воздействия грунтовых вод и проводить берегоукрепительные работы на высоком профессиональном уровне.
