Stabilization and strengthening of industrial buildings foundations

Геополимеры широко используют для восстановления и ремонта производственных и промышленных объектов. Смолы на основе геопролимерных материалов подходят, как для укрепления фундаментов работающих предприятий, так и для модернизации неиспользуемых объектов под более мощное оборудование.

Многие промышленные и производственные объекты подвержены регулярным избыточным нагрузкам. В зависимости от особенностей рабочего цикла предприятия, это могут быть, как статические нагрузки, так и длительные динамические воздействия.

В результате подобных нагрузок происходит уплотнение грунта под плитами пола нижнего этажа и под отдельными участками фундамента сооружения. Подобные уплотнения нередко провоцируют просадку фундамента и пола, что может вызывать нарушение конструктивных характеристик сооружения. Для устранения просадок можно задействовать методы инъектинования геополимерных смол под фундамент здания или под плиты пола нижнего этажа.

Устранение конструктивных повреждений здания

Одна из распространенных проблем, которая нередко возникает на производстве, связана с эксплуатацией мостовых кранов. При регулярном перемещении больших грузов, на опоры крана создаются неравномерные динамические нагрузки. В результате грунт под отдельными опорами может уплотниться сильнее, чем под остальными, и произойдет неравномерная просадка всей конструкции. А в случае если опоры крана дополнительно являются элементами несущей конструкции здания, может возникнуть нарушение геометрии сооружения с риском разрушения всего объекта.

Чтобы укрепить несущий каркас здания и стабилизировать состояние мостового крана, в грунт под фундаментом просевших опор необходимо инъектировать геополимерные смолы. В результате может быть улучшено состояние не только самого крана, но и сооружения.

Укрепление фундаментов предприятий

Выполнять инъектирование для усиления грунта под фундаментом промышленных объектов можно без остановки производственного цикла. Инъекции делают с помощью небольших мобильных установок, которые вводят геополимерный материал через технологические скважины, пробуренные в полу нижнего этажа или в примыкающем к зданию покрытии (грунте). Для инъектирования геополимерных смол применяют трубки небольшого диаметра. Структурирование и затвердевание материала происходит всего за несколько минут.

При этом использование геополимеров в случае наличия избыточных динамических нагрузок может быть не менее эффективным, чем без них. Дело в том, что геополимеры отличаются эластичностью и способность к восстановлению объема после окончания избыточного воздействия.

Subsidence stabilization

Наращивание мощностей предприятий

Восстановление заброшенных и неиспользуемых промышленных объектов нередко сопровождается необходимостью применения более мощного оборудования, которое создает увеличенные нагрузки на пол нижнего этажа и фундамент здания. В случае если эти нагрузки превосходят допустимый предел, грунт под полом нижнего этажа или под фундаментом также нужно усилить.

Для усиления фундамента с помощью геополимеров применяют метод глубинного инъектирования Deep Lifting, когда введение материала в грунт осуществляют на значительную глубину. Кроме того, для усиления пола нижнего этажа помещения можно выполнять инъектирование по методу Floor Lifting. Выполнение инъекций возможно, как до, так и после установки нового оборудования. Введение геополимеров проводят до тех пор, пока несущая способность грунта основания сооружения не будет соответствовать нормативному значению.

So is there any differences in the application of your technologies in industry from use for private houses?

Aleksandr Efimchik (inzhener GROUNDTEK) Dec. 13, 2020

Theoretically, there is no process of essential difference.The difference is only on the scale of projects and various requirements for the project and work.From our practice we can say that the private residential sector has more standard problems than commercial organizations in view of their functional diversity.Therefore, the tasks and conditions differ, although the causes of the emergence of inconvenience and destruction remain among the same.

And how do you calculate the permissible loads that are kept or can withstand floor slabs for example in stock, after your work?

Evgenij Novitskij (inzhener GROUNDTEK) Dec. 13, 2021

All materials are certified and investigated in European laboratories (including NIPI HERSEVANOV).Therefore, there are special engineering technical bulletins that use GroundTek engineers to select a material for a specific task as part of a technical solution.

Basov Aleksandr· Oct. 21, 2019

Is it important to set the maximum load on the raised area?For example, to strengthen the site of the same bridge crane when the crane itself is not there, he will again sit down or is it not a sure judgment?

Evgenij Novitskij (inzhener GROUNDTEK) Oct. 21, 2019

Not necessarily, but preferably from the point of view of economic efficiency.There is a large list of materials as suitable as possible for various tasks.It is important to know the design load, the material is selected under it by default, the material is selected with the desired characteristics, if it is possible to create it artificially, then you can use a cheapest material that in the course of work will take the desired density and quality under artificial loads.Therefore, it is an economic question, and not technical.

Aleksandr Efimchik (inzhener GROUNDTEK) July 25, 2021

Yes, of course.But for the project development, data are necessary on the characteristics of the soils of the future base and the load from the future structure, that is, the construction project.

Evgenij Novitskij (inzhener GROUNDTEK) Oct. 23, 2021

In general, no, no radical interference is required to processes.The place of work is a plot of 2 * 2 meters at the same time it is mobile and if this site is required for the needs of the customer, it is released during the time required.Part of the Work Plan is the coordination of convenient time windows when the required sections are available for operational use.

Aleksandr Sinchenko (inzhener GROUNDTEK) Dec. 21, 2020

Vibration should be tested: work either with a source or with a receiver, or simultaneously with both sections.To do this, you can use dense and simultaneously elastic materials capable of damping oscillations and maintain designs in working condition.

Evgenij Novitskij (inzhener GROUNDTEK) Dec. 25, 2020

The pile foundation is the most reliable and therefore the most difficult, if he still begins to bring the owner of the building.But even in this situation, you can find a solution and implement with the help of grained technologies.It is important to understand the situation to start and find the root cause of what is happening.

The question does not have a unambiguous answer ... Of course, it is necessary to do everything normally and not to move away from the project.But it does not happen.The project tends to modify in the course of its implementation, and as specifically it will be - guess fail.

It all depends on the "swampiness" of this area.The number of organic matter in the ground is critical to apply any solution.Therefore, only specific data can answer this question.
