Screw piles for a fence: features of the choice and subtlety of installation
Ever since ancient times, people have sought to protect their territory. At a minimum, that their private house or cottage to avoid prying eyes. But the fence also allows you to protect yourself and mark the boundaries of your territory. In this case, we must not forget that it must be of high quality, presentable, strong and have an affordable price. And under all these parameters are suitable screw piles, which have already gained popularity both in Europe and in the CIS countries.
And the main feature of screw piles is that they can be safely built in unstable soils.Supports can be installed on any soil, even in swampy areas, which is undoubtedly a great advantage of this type of attachment.
What it is?
A screw pile is a metal pile that has a screw blade at the end. Piles are divided by types of thread section. There are several types of threads: standard, with blades and combined. Piles with different types of threads differ not only in appearance, but also in the load they are able to withstand, and for how long they can last.
Features of the choice of screw piles
The most robust and expensive are screw piles with blades. Basically, they have two blades. Such piles, despite their high cost, are the most popular because they are the most durable, they can be placed on any kind of soil.
The bearing possibility of fastening directly depends on its diameter. The thicker the diameter of the pile, the more weight the structure itself can withstand.
When choosing piles, you need to take into account the features of your future fence.
Piles with a diameter of 57-219 mm are especially popular. Smaller diameter value is suitable if you want to build a foundation under a metal grid or picket fence. The average value is used for the fence of the corrugated.And the larger diameter value is suitable for heavyweight cladding.
The next criterion for selection is the type of tip. The tip can be either welded or cast. The most durable are piles with cast tips. They are bought infrequently, they are used in the construction of very heavy structures.
Next, you must determine the length of the product. There are constructions from 1 meter to 11 in the market. You should also pay attention to whether there is a corrosion-resistant coating.
So, what you need to know for the right choice:
- soil composition;
- the depth of soil freezing in your area;
- material from which construction will be made.
Do not forget to check the quality certificate or passport of the product upon purchase. The structures themselves should not have weld seams, the corrosive coating should be applied not by an artisanal, but by an industrial method.
The most important advantage is the price of the product, since the screw piles are not the most expensive on the market, with this material you save about 40-60 percent. Another advantage is that one pile can withstand a load of a couple of tons.It can be installed by hand, as this process is quite simple.
The construction of such a fence will allow you to avoid unnecessary costs, since during the construction of the fence on a strip base you would have to dig a whole trench. And if you wanted to have a columnar foundation, you would need to dig separate holes for each column. And the main obstacle to the usual fence would be the opportunity to stumble on the groundwater - all this does not matter in the construction of screw piles.
Also you save on filling of the basis with concrete. Such pouring is a very difficult but necessary stage of construction, which no longer allows you to build a fence with your own hands without special skills. All these actions are unnecessary when building a fence from screw piles. The only thing that may be required is to tie the products together with a metal profile to strengthen the structure.
The mechanism itself can be installed at any time of the year, it is not for nothing that they are mounted even in permafrost conditions, which is undoubtedly a plus. Such a fence can stand for more than a century.
The advantage is easy dismantling, the ability to reinstall the fence to another location.
The installation mechanism is simple, everyone can deal with it, since it is possible to twist the piles into the ground without special equipment. The time you spend on screwing in one pile is about 20-30 minutes.
Preparation of materials
When installing you will need a number of materials and tools. Choose high-quality materials, as this will envy the strength of the structure and the time it will serve you.
It is necessary to take into account a number of parameters:
- weight and dimensions of the material from which the fence itself will be made;
- probable wind load.
You need to purchase:
- guides for fastening;
- pillars for the gate.
You can also purchase if you wish, the material that you will need in the future:
- forged sections;
- wooden fence;
- welded mesh with polymer coating;
- metallic profile;
- concrete spans.
Here you need to focus not only on quality but also on design. The choice on the market is very large - buy what you like. And always pay attention to the wind resistance, height and weight of the product, so that further piles are suitable for this type of fence.
Installation rules and tips
When installing, as with any type of construction work, there are often some nuances that must be taken into account. Before you begin to twist the fasteners, you need to make a test screw-in to determine the possible level of depth of the structure. This will depend solely on the composition of the soil. If the ground is very strong, then the piles can be immersed to a depth of about 1.5 meters.
After that, do not forget to designate the perimeter of your fence, be sure to consider the presence of underground communications that can pass under your fence, in order to avoid unpleasant incidents.
When erecting a structure on moisture-saturated soils, do not forget to lay the foundation below the ground freezing level - this is necessary so that during the seasonal changes, the attachment does not occur.
The piling itself can be carried out with the help of specialists (if there is a financial opportunity) or independently. To install the piles, you will need two assistants and a special gate (which you can buy or make yourself).
To create such a product, you will need fittings (d = 3 cm), which is inserted into a special technological hole. On both sides it is recommended to wear square tube segments that will act as levers in the future. The optimal length of such a product will be approximately three meters.
Recommendations from experienced builders
- If you start to feel a strong tension when screwing in, stop. This can damage metal.
- It is better to screw the pile in three together, so that the third one directs the pile and watches its direction.
- Do not use a lot of effort, if there is any obstacle on the way - you can also deform the material. In this case, it is better to use a drill, but it should be smaller in diameter than a pile.
- At first it is worth twisting angular piles - with this cunning you will achieve evenness of a fence.
You need to calculate the number of piles, taking into account that the step between them should be approximately two and a half meters. Yes, in some cases it is possible to install supports three meters apart, but no more than that. In the places of the installation of piles make a small recess - it will help you in the future when screwing.Place the pegs in the corners of your section, draw a thread between them.
You need to carefully regulate the verticality of the pile entry into the soil. This is necessary even when installing conventional pillars. Otherwise, a lot of effort will need to be spent on refining the shortcomings and leveling the fence. In order to achieve a smooth vertical entry, it is better to use a special tool.
So, we come to the crucial moment - it is the twisting of the piles. As stated earlier, do not forget to prepare the material, the surface of the soil and invite two assistants. And take care that the lever with which you will twist, withstood the load.
Check the marking of the points for the supports and the size of the recess. Install the side poles (thus having gotten to install). Then you can mount intermediate piles. And remember that in the future to correct the vertical pile is no longer possible.
After installing all the piles, you need to align the head with respect to each other (for this you can use the grinder). But the depth should basically be at least one and a half meters.
Further, if you plan to install a heavy fence - use a special solution M-150. To them you must strengthen the place of the pile out of the ground. And in any case, it is recommended to fill the cavities with concrete solution to achieve maximum structural strength. Also fill will increase the moisture resistance of the structure. You can fill the above-ground part with a primer and an anti-corrosion solution.
Next, you need to install guides, which will serve simultaneously as strapping, and then proceed to the installation of racks, to which you can attach the filling in the future.
Mainly used profiled, as it looks aesthetically pleasing and has a low cost.
It is better to install profiled sheeting parallel to the supporting pillars. Before installing the sheet for the first time, it is necessary to make all measurements correctly to avoid distortions. To do this, it is better to once again hold the construction thread between the columns, you will be able to navigate along it when installing the cladding. The first sheet is applied to the lag, if all measurements are correct, you can fix it. All subsequent sheets fasten, focusing on the previous one.It is better to re-measure several times in order to avoid unpleasant skewing at this stage of work.
After fixing the cladding, you can proceed to the installation of gates and wickets.
Driven pile posts or their brick counterpart have only positive feedback. Follow the installation instructions carefully, and the fence will last you a long time, while remaining as strong.
In this article you were able to familiarize yourself with the peculiarities of the choice of piles, with the subtleties during the installation of the fence and the guidance on how to build a fence on your own. If the mount is installed correctly, your fence will last for many years. It is because of the low prices and reliable quality piles are so popular in the market of building materials.
