You will need
- - special equipment;
- - steel sheet;
- - screws;
- - longitudinal welded pipe;
- - vulcanicola cutting saw;
- metal piles.
Make the calculation of the blades of screw piles. This procedure is similar to the event related to the calculation of the feathers of the screws. In other words, determine the pitch, diameter and length of screw piles.
Special equipment do the cutting of the steel sheet. Then produce the rolling and stretching of the sheet.
If you have finished screws, by welding attach them to metal poles. In this case, the stem screw piles can be longitudinally welded pipes, which have to comply with the requirements of GOST. For the manufacture of prjamoshovnyh pipes should be used steel grade article 10, the blades shall be manufactured of steel grade St 3 (typically, its thickness is five millimeters).
The shape of the tip of the pile stem run like it in appearance resembled a smooth cone (if the form is different, it will complicate the process of installation of trunks and increase the likelihood of failures).
Cut pipe using saws vulcanicola uniform sector sizes. Carefully strip the data sector. Then weld on the tip of a screw prepared in advance.
Programsuite all the welds - this will prevent corrosion of the metal used, and therefore prolong the operational period of the product.
On the opposite end of screw piles drill a hole in it when installing screw piles into the ground is inserted a crowbar.
Ensure that the screw piles were in the ground vertically, otherwise the Foundation will not be stable, as expected.
The speed of installation of screw piles directly proportional to the pitch. In view of this, the pile with a large pitch is meant to backwashing a sand soil (it is very slightly loosens the soil). Thus, if the soil is dense, it is recommended to use piles with a small step.
