Screw piles. Making screw piles with your own hands is a very complex and time-consuming process that requires a high concentration of attention. Most experts do not recommend making them yourself, as they believe that for this you need to know all the technologies. But if you read this article carefully, you can make screw piles yourself.
The screw pile is similar to a propeller, it is an empty, metal flask.
It has a pointed end, with a cutting tool in the form of a spiral.
From its angle of inclination and technology depends on how it will enter the ground.
Thanks to the spiral tip, the pile will enter the subgrade to the depth you need. But on the reverse side, this blade will interfere with the fixation of the pile in the ground and will push it outward.
With this design, during the installation of the foundation base, it will allow you to work without additional, cargo tools.
When drawing up a structure, you can be guided by the plans of various manufacturers of screw piles.
This will help to very accurately reproduce the dimensions of the blade and keep seams to a minimum, as they make it difficult to work in the place where the joints occur. There are three completely different types of handpieces.
This product requires doubling the pipe length, since the first end of the product will be converted into a tip.
While marking, remember:
for a pipe with a diameter of 100-200 mm, it is most convenient to make five petals.
For 70-89, four is enough.
The result is a tapered lance, very convenient for welding helical blades.
For the foundation of small buildings, this option is most often used.
Manufacturing technology :
After that, processing takes place by welding, double seam along the edges.
Manufacturing technology:
The optimal pitch of the blade spiral is 70-80 mm. The spiral starts from the third part of the pipe from the bottom.
Here are two examples for making blades:
For a more durable operation of screw piles, it is necessary to cover with some kind of anti-corrosion agent.
During each year, pipes can lose up to 1 millimeter in thickness due to rust.
Screwing the pile into the ground can be done independently. The most common device for this is a metal pipe, previously inserted into the hinges. They are made of 10 mm diameter reinforcement. This pipe is pushed, resembling a lever, thereby screwing the pile into the ground.
Sequence of actions :
5 meters.
