What to look for when choosing metal piles

Accordingly, the cross-section of the metal pile should be increased 2.5-3 times compared to the initial one in a height section of 2.5-3 diameters. This also allows you to avoid a local loss of stability if one of the corners of the lower end of the pile meets a rock earlier than the other. Strengthening the ends of the piles is not always done if the rock is covered with a sufficient layer of dense soil, such as 2-2.5 m orthstand, 2.5-3 m gravel, 3-3.5 m of sand or 3.5-4.5 m of solid clay. Oslo type tips are often used in Norway and Sweden for H-swea and other metal piles, clogged to the cliff, if the latter has an inclined surface. The tips are hardened steel rods with a diameter of 7.5-10 cm, released several centimeters below the end of the pile. In H-svai, a strip in the wall is cut out and the rod is welded to this place. The ends of the rods knock out the pits in the rock, so that sharp edges can prevent pile shifts along the rock. The clog is performed in the same way as when working with a donkey. For crushing the cliff, a hammer is used, which can work with reduced beats of shock. These tips allow you to avoid eccentricity from the pile that is uneven on the rock and protect the pile foundation from displacement along the inclined surface of the cliff.

They consist of four or thicker ribs in the form of plates, cast or welded outside the conical sharp. Steel crosses welded to the flat bottom of the tubular piles are used to facilitate the passage of obstacles and a dense connection to the rock. The immersion is carried out by the shock-rotational method.
