The use of piles for construction on water was the initial means of creating a persistent foundation on the watery surface. Irish engineer Alexander Mitchell opened this technology, who used screw supports when erecting a lighthouse at the mouth of the Thames River in the far of 1838. In connection with the hard -to -the location of the lighthouse, it was impossible to use, at that time popular, at that time, it was impossible, so the resourceful engineer and it occurred to make the lower pile cone in the form of a screw. Further, this method of construction came to the taste of American engineers and over time, as well as after some external changes, the products have gained a modern look.
What gives the foundation from screw piles on the planted soil
To date, the scope of screw piles is widespread to berths, bridges, coastal houses and many other objects of which the location of which requires a more difficult approach in their construction. This foundation is a universal guarantor of the resistance of the structure on the most unstable soil. In addition, modern piles have an excellent indicator of durability. For all these advantages, the technology is used in any time of the year, without involving expensive special equipment or heavy equipment to the work.
The whole secret of screw supports is hidden in the blades of the product located on the edge of the product, from the side of introduction into the ground. This structural element allows you to screw pile into the ground, like a self -tapping screw, without the use of shock technology. The blade also betrays a great resistance to factors of external influence, such as compression, bending, or expulsion from the earthen rocks.
Installation of screw piles during construction on water
During the installation of the supports in the areas of water covered with water, special attention should be divided into current speeds and a breed of soil into which the foundation will be introduced. With a weak current, they will be a stable means of support on the water even for an entire house, and with strong, additional measures (concrete injections or reinforcement) should be taken.
The installation itself should be carried out in the winter period of the year, when the water cover is overlapped (if the climate allows), in this case, the installation will require a smaller amount of special equipment, it will be more economical and safe.
After installing the pile foundation, it should be expected to be carefully and carefully, paying attention to all sorts of trifles.
