Fiberglass anchors The technology is based on the use of fiberglass (fiberglass) tapes as anchor rod. Fiberglass traction ground anchor Advantages of fiberglass rod anchors: - Good adhesion of the fiberglass rod to the cement stone due to the rough surface of the rod material. - Fiberglass rods are supplied in coils of 100 m length. Therefore, the anchor rod can be installed in any length without connecting elements and welds. - Low weight of the anchors, which greatly simplifies the transportation and installation of the anchor without the involvement of lifting mechanisms. - Relatively low cost of anchor rod, comparable to the cost of steel reinforcing bars. - Corrosion resistance, allowing the installation of anchors in aggressive environments. Установка фибергласового анкера Технология устройства анкеров из фибергласовых тяг состоит из следующих операций: 1. Бурение скважины. 2. Установка в скважину анкера, состоящего из фибергласовых тяг в количестве 1—3 шт. (в зависимости от требуемой нагрузки) и одной инъекционной трубки. 3. Заполнение скважины цементным раствором до излива раствора через устье скважины. В случае ухода раствора (понижения зеркала в устье скважины) операцию следует повторить 2—3 раза через 25—30 мин. 4. Натяжение анкера до расчетной нагрузки. Натяжение фибергласового анкера Note that most often the installation of anchors is carried out with one injection tube. However, in some cases, in order to increase the bearing capacity along the ground, it is possible to install a second injection tube, allowing for secondary injection.
