The base on screw piles differs in high rates of durability and the long operational period. So, screw piles become to irreplaceable construction "material", and their production gains improbable steam.
It is required to you
- - special equipment;
- - steel sheet;
- - screws;
- - straight-line-seam pipes;
- - vulkanitovy detachable saw;
- - metal piles.
Instruction
1. Make calculation of blades of screw piles. This procedure is similar to the action connected with calculation of feathers of screws. In other words, define propeller pitch, its diameter and length of screw piles.
2. On the special equipment execute cutting of steel sheet. After that make rolling and extension of leaf.
3. If there are ready screws, then by welding attach them to metal piles. In this case straight-line-seam pipes which have to conform to requirements of state standard specification can act as stem screw piles. For production of pryamoshovany pipes steel of the brand of Article 10 has to be used, at the same time blades have to be manufactured of steel of the brand of Article 3 (as a rule, its thickness is five millimeters).
4. Execute form of tip of pile trunk such that it on the exterior reminded equal cone (if the form is another, then these are a little will complicate process of installation of trunks and will increase the probability of emergence of failures).
5. Cut on pipes by means of vulkanitovy detachable saw sectors, flat by the sizes. Properly smooth out these sectors. Then weld the screw prepared in advance on tip.
6. Progruntuyte all welding points - it will prevent corrosion of the used metal, so will prolong the operational period of product.
7. On the opposite end of screw pile drill opening - scrap will be inserted into it when mounting screw pile in soil.
