Screw pile – metal construction design

When examining the basis of the draft plan and the specific areas of geology, determine the approximate length of the pile, the necessary screw pile sizes and quantities as to ensure maximum quality results. “RST SKRŪPĀĻI” Ltd. taking into account the specific construction project and soil bearing capacity, develop the most suitable offer for you to have ready to pile the parameters required for a particular object. “RST SKRŪVPĀĻI” Ltd. offers to design from scratch or redesign of the foundations of the building of monolithic concrete foundations to screw pile, as well as offering a variety of metal structures design, hangars, etc.

Manufacturing of screw piles

We offer produced single, two, three or four blade screw pile, rod screw pile possible types are manufactured from round pipes (diameter of 60.3 mm-159mm thickness 3mm-8mm) and the square (size of 60x60mm-120x120mm thickness of 3mm -8mm). Pile bearing capacity, depending on the type, is from 0.5 t up to 35t. The blade diameter ranging from 150mm to 500mm, thickness from 5mm to 12mm. If required in a different way screw pile construction, or if there should be a greater load of 35t, then it should be considered separately.

Assembling of screw piles

Not later than one week after signing the contract with “RST SKRŪVPĀĻI”, the site is launched screw pile installation. Screw pile installation will depend on both the nature of the object and the amount of pile-mounted, but under normal circumstances assemble approximately 15 to 20 day screw pile. Mounting screw pile can be made in two ways by “RST SKRŪVPĀĻI”Ltd.:
▪ Installation of hand at this type of assembly is not in use any equipment exclusively handmade, resulting in no damage to the lawn or plantings, this type of assembly is used more often in a situation where the screw pile to be installed either in the patios, terraces, small quantities, or in places where it is not possible to access technical
▪ Installation with mini excavator with this type of installation it is possible to spoil a little lawn mini excavator, that is equipped with rubber chains, this type of installation is generally used in larger installations.

When installing the screw pile or by hand or technique has no vibration, noise. For example, forcing concrete piles have observed a large ground vibration as a result of the proximity of the building to the weak or unstable foundations are possible cracking of walls or buildings collapsing.
Screw pile during installation can also be extended by the addition of sections with or without blade screw pile length from 0.5 to unlimited, screw pile can be extended to the desired length, until reaching the soil supporting layer, elongation stages are either 1m, 2m, 3m. In order to be able to provide a screw pile design load is to go into the ground supporting lyer at least about 1.5 m depth.
Generally screw pile is located 1.5 to 3 meters from each other, and at least three blade diameter, depending on the design load and soil load-bearing capacity. Pressure carried by each screw pile is facing down, which is proportional to the torque fitting, and depends on the soil in which the thread is made to spin.
Latvian climatic conditions tightened when screw pile is not less than 1.5 meters deep, but on the basis of technical regulations, screw pile screw so deep, until reaching the soil supporting layer which it is Recessed around at least 1.5m. To be able to determine what needed screw pile and depth of what they should be carried out geological bore. In the event that a situation arises when the soil bearing capacity is lower than planned, then increased lengths of screw pile.

Verification of screw pile load

After mounting screw pile is possible to screw pile static load test, although it is possible to check and compressibility, it is also loaded with a screw pile as much pressure as required under the weight of the designer (t) is designed for a specific site, although it is also possible to test-drive the screw pile extraction, as not always screw pile load must be taken against pressure, but in some cases the extraction.

Such services is offered by “RST SKŪVPĀĻI” Ltd. for the product, screw pile load testing does not include installation in the price.
Screw pile load test can be made either by the entire pile installation and assembly of the first pile. (It depends on the client’s wishes.) Screw pile installation can therefore be determined, what will be the approximate load-bearing capacity of each pile, removing the performance of the gauge.

Concreting works

“RST SKRŪVPĀĻI” Ltd. offers a variety of concreting work on the pile mounting piles usually something that has to be put on top of so-called belt with the help of mutual over the top of the screw pile is bound. Generally, there are three options that are used as wood, metal, reinforced concrete.

Concrete casting is usually used when the house was built of blocks of concrete chooses the cases when things are monolithic floor, as if the home base screw pile technology is used, the concrete during the floor it is not a sealed base form inside as the classic version, but it is a sealed top monoliths belt is built to screw pile, usually monolithic belt width dimensions of 200mm-400mm height of 400mm-800mm.
“RST SKRŪVPĀĻI” Ltd. will not be offered the above belt concreting are offered all concrete works, foundations, floors, walls, etc.

Metal constructions

Since 2014 „RST Skrūvpāļi” Ltd., expanding its offer, offers to manufacture and assemble different metal constructions.

In most cases with screw piles, particularly different buildings, hangars, warehouses, advertising posts of metal constructions are being assembled.
That is why our enterprise offers full work cycle
-assembling of screw piles
- concreting
- metal frame
