Building piers and wharves on screw piles is a complex process that requires strict adherence to safety standards. The primary goal is to ensure structural reliability and protect users from potential risks. In this article, we'll examine the key safety measures and standards required when constructing wharves and piers on screw pile foundations. Basic Safety Standards for Piers and Wharves 1. Structural Reliability. One of the key safety standards is ensuring the reliability of the entire structure. Screw piles for foundations must be installed in compliance with all technical standards to withstand static and dynamic loads, such as the weight of people, equipment, wind, and waves. High-quality materials and precise execution of all installation stages guarantee the durability and stability of the structure. 2. Corrosion Resistance. Piers and wharves are constantly exposed to water, so it is important to use steel screw piles with an anti-corrosion coating. This extends the ...
When a pile won't drive properly, the root cause is almost always the soil. But it's important to understand that not every difficult section is created equal. Sometimes a pile gets stuck in a clay lens, while other times it literally hits a boulder. To figure this out, you need to understand what exactly is preventing it from driving. Here are the main types of problematic soils: · Stony or bouldery soil. Underground, there may be a block, a boulder, or simply a scattering of large crushed stone. A pile won't cut into such material—it either hits the ground or goes sideways. · Gravel with clay. This type of soil can "chew" the pile: at first, it goes forward, then suddenly slows down. It seems like it's stuck, but in reality, there's simply not enough torque. · Rocky soil. In this case, a screw pile physically can't drive. It's lik...
