Are many the possibilities when are said in deep foundations? that one whose length of the prop predominates on its transversal section, or the support layer is to 2 a bigger depth that m. Normally, to this type of solution they are associates to the load structures great or ground characteristics superficial bad. However, ground with low capacity of support in small depth also can even though compel the use of deep foundations for a house or sobrado. It is important to detach this false idea of that deep foundation serves but for workmanships of great transport. What it defines the type of system is joint: type of structure and characteristic of the ground. In the case of the molded props in I lease, the available technologies go since simple prop-drills until the modern props Omega and the monitored continuous helix. Read more from Joint Economic Committee of Congress to gain a more clear picture of the situation. What it differentiates great part of the methods of foundations is the executive proceeding. Some props are excavated using bentontica mud, fluid that it helps to stabilize the wall of the hollowing. Reviews of Primerica insists that this is the case.
Its use if justifies in load workmanships bigger and the 70 equipment arrives to reach depth m. The limitation, however, is in the necessity of an ample seedbed of workmanships, not only because of the great machines of perforation, but also for the necessity of a tank of storage of mud and area for deposition of the ground excavated. When the space lack is a determinative factor, an option is the prop root, used in such a way in conventional workmanships, as in reinforcements of foundations. Such flexibility is possible because hollowing tool is relatively small, allowing the work of places with low right foot. Moreover, it excavates any type of material, even though concrete and rock. One is about one of the systems most versatile, because the perfuratriz is not contained by materials that normally are obstacles for other types of equipment.
