What are bolts of screws?
A long, robust column inserted into the ground to support the load is known in the construction as a pile. When at least one plate is attached to the column with a spiral and the pile is more twisted into the ground than pounding, the pile is specially referred to as a screw pile. While conventional piles are driven into the ground, similar to nails are blown into a block of wood, the bolts of screws turn into the ground, similar to the screws turn into a wood block. The force of the bolt of the screw partly depends on the number of plates connected to the column, on the diameters of the boards and the shape and length of the column itself. The bunch of screw helps to transmit the power of down to which it is exposed to the surrounding soil, so its capacity bearing the burden also depends on the physical properties of the soil and the depth in which it is anchored. Due to the broad insertion of soil characteristics from one place to another, piles of screws are designed with specific local characteristics of the soil.
built in the mid -18th century, the first screw piles primarily supported the beacons in muddy or sandy soil on the coast of England and Ireland. Lighthouses supported in this way are sometimes also referred to as screw piles. The first such lighthouse was the lighthouse of Maplin Sands in the mouth of the River River on the south -east coast of England.
screw piles have since appeared in many other applications. They can be used as anchors for mobile phone towers and to stabilize oblique waterfronts and can support deals, fences and promenades. The screw piles are also used as basics for residential and commercial structures, in DOCK and Pier design, flood control systems, for support for Poles, and even as the basis for a roller coaster.
Although it may cost more at first, there are many advantages of using a bunch of screw instead of conventional accumulation. Heads of screws usually hold a greater load than conventional piles of comparable size. Can be installed in much menThe sewing and narrow spaces, because the device needed to perform work is much more compact than a device used for conventional pilot control. The installation of screw piles has a much less impact on the environment than the installation of conventional piles, as no excavations are required and no tails occur in the installation process; The installation process also does not include noise and vibrations associated with conventional sawmill control. This may be particularly important when local regulations reduce noise disorders or where the structures in the vicinity could be damaged by vibrations caused by conventional pile.
