Screw piles for the fence - installation, advantages and disadvantages
The trend of the last ten years in the field of construction special attention to the details of the facade of buildings on the land plot, landscape design, as well as the creation of exterior finishing elements that meet modern ideas about aesthetics and functionality has become.
The choice of design, installation technology, material for the fence is included in the number of priority tasks. Fences will become an external reflection of taste, as well as the status of the property owner. An incredibly beautiful, durable fence that does not lose its beauty for a long time is the result of a well-chosen project and its high quality implementation.
One of the main factors was the competent choice of the supporting "skeleton".
This will depend not only on the capabilities of the site owner, but also on the quality indicators of the soil used in the finishing of materials. let's talk about screw piles under the fence.
Construction technologies of supporting structures are improved every year. Conventionally, this type of work can be divided into 2 categories. The first can be attributed to the foundation method, when the base is a one-piece structure along the entire perimeter, and the second method consists in point support fixation.
For centuries, the assembly technology of a single support structure has been used. Technologically, people were not ready for the widespread use of pile structures, which were used only in those regions where other methods did not work. To date, the construction industry has made it possible to use this method on any soil, in different climate zones.
As practice has shown, in a large number of cases, a fence on screw-type piles is better than the traditional one. Manufacturers and designers offer the entire set of required elements in order to solve this problem.
The obvious advantages of the method include:
All of the above technical advantages will become the basis for the economic benefits of using screw piles. A small number of elements, building materials, the bulk will make it possible to assert that the price according to the construction estimate is less than with other methods of installing the fence. If, when arranging the base, a large proportion of the time and labor costs are ground work, then in this case their implementation is not necessary.Usually foundations are made by pouring a sand-cement calculation.
For the satisfactory quality of further operations, it is required to give time for the mortar to harden, and also concrete shrinkage. Experts are advised to withstand at least a week before the start of the next installation work. Fence screw piles are ready for future operations immediately after installation.
In weak or moving ground, when it is required to make a deepening of at least 1 meter to obtain structural strength, the option of using a screwed pile looks like a worthy alternative ..
. It also solves a number of complex financial and technical problems. But there are also technical nuances in which installation work for screw piles is impossible or difficult. Rocky soils are an insurmountable obstacle to using this method. The advantages include the ability to do the installation with your own hands without the involvement of additional workers and equipment.
This fact makes it beautiful to install piles not just for a fence, but also as a foundation for auxiliary and main buildings on the site.
But an independent decision about the application of this method without an appropriate land examination can lead to complete disappointment. It is not just the presence of rock layers that can affect structural strength. High groundwater, which means mobile soils at a greater depth than usual. Such places can often be found in the armholes of lakes, rivers, in dry swamps.
A layer of peat is not the most reliable base, and such places are often covered with imported soil. The layer thickness can be up to a couple of meters in some areas. In this case, the length of the part of the piles underground must be increased in the same way as for areas with permanent permafrost - up to 4 meters.
The selection of models will be based on the consideration of what specific tasks will be solved and what is required for this. First of all, it is required to analyze the land plot.
It will not be superfluous to take advice from neighbors, owners of real estate, which is located nearby. Information can be obtained from regional geodetic services, where there are soil maps of the development area. Obtaining real data on the quality soil composition, its layer, strength, and even the depth of freezing, you can choose piles for the fence of the required design. Manufacturers offer a chic assortment of product lengths. The ideal pipe diameter for polycarbonate, wood, polymer fencing is not less than 5.
5 cm. For a metal product, 7.5 cm, and a stone fence involves the use of piles with a diameter greater than 10 cm.
The depth to which you need to install pipes, varies depending on the quality of the earth. Statistics have shown that the stable layer will lie below the surface below 1.
8 meters in a large number of cases. In many regions, this figure may be lower, and sometimes higher.The light weight of the fence cannot be a reason for rejecting such a rule. A smaller indentation is fraught with dynamic changes in design during the first couple of use. Places for mounting wickets or gates need reinforcement.
In the design drawing up, such screw piles for the fence are taken into account by the piece. We advise you to buy products with a large diameter for such purposes.
When choosing elements for the support structure, it is recommended to pay special attention to this aspect. Depending on the quality of the earth, pipes with a certain type of screw element are chosen. The pile tip can be made in different versions:
By the way, the latter type is the most suitable for lightweight structures. The blades will screw perfectly into the ground. After installing the fence on screw piles, the weight of the structure will not exert a critical load.
The molded tip is perfect for high fences and large block or brick structures. More detailed information (including technical) about the use of screw piles as a base for a fence is presented in the video.
Correct work organization helps to reduce costs, and also speeds up work. The main thing is that the quality will meet the needs. After the design drawing up, you can start making the fence immediately on the piles.
Step by step construction looks like this.
Territorial markup. A fishing line, construction cord or thread from any material with high strength is pulled along the perimeter of the site. Each pile is marked. By means of a hydraulic, laser level, horizontal marks are set, which indicate the upper pipe level.
With soil irregularities, the question of the configuration of the fence is decided. The fence can be made:
When marking, indicate which pipe is required for installation. In place of the gate or wicket, a more reliable and with a large diameter pile is mounted. During the workflow, this can be ignored, and the mark will remind you that a different pipe should be in such a place. Even experienced craftsmen are unnecessary reminders.
The main operation in building a fence.
Under industrial conditions, special equipment is used. The very process of screwing into the ground is very similar to working with self-tapping screws. The screw parts of the product by means of the blades cut the ground, resting on it, and then continues downward movement exclusively by rotation around its axis. With your own handwritten work, you need to take into account the nuances of starting the operation. The entry is made under heavy load to avoid the plowing effect.
The motion vector will have a downward direction. With rocky ground, it is sometimes advisable to knock piles until they begin to move independently along a well-thought-out route. After a high-quality entry, efforts can be directed only on the rotation of the pipe.
Depending on the quality of the land and the physical capabilities of the workers, 2-5 people are involved. The pipes have through holes, usually 2, into which the lever is inserted.
You can use rebar, scrap or metal bar. The moment of entry is controlled by plumb lines or a building level. It is important to set the correct direction for the pile, and it is more difficult to mount the pipes yourself. Easier to perform the operation with an assistant. The third person in the process is able to control the direction of approach and help with the vertical load during the initial movements.
Pipes with a large diameter with a large depression are easier to twist in four, on both on each of the two levers.
When the desired depth is reached, you can stop screwing. Next, check the height against the horizontal mark. If necessary, the pile needs to be cut off or an additional pipe piece welded on. We strongly advise you to fill the inner cavity with a concrete mixture.
So the strength will increase, oxygen is blocked inside, which slows down the corrosive effect. It is difficult to achieve the ideal vertical position with manual installation. For this reason, experts choose pipes that, after installation, will be located above ground level no more than 0.5 meters above the ground. Next, a cheaper pipe is welded, which is much easier to put vertically.
In certain cases, it is more expedient to make a concrete lining of the structure, thus eliminating the technological gap between the ground and the decorative facing. At the same time, the strength and reliability of the structure will greatly increase.
Design, materials for decorating the fence. After the installation of the screw piles for the fence has been made, you can proceed to a new step - the installation of the fence and decorative cladding. Reliable support structure allows the use of all types of building materials:
- Polymer panels, sheets.
- Building blocks, bricks.
- Wooden lumber.
- Profiles, metal panels and picket fence.
- Sheet metal or corrugated board.
- Reinforced concrete slabs.
Preparation for editing does not differ from similar operations for the rest of the basics. The requirements and rules are the same. The required distance between the load-bearing horizontal structural elements is maintained.If the lathing is important, then the calculation of the dimensions is carried out according to the general rules. A popular filling material is wood.
screw piles are the ideal foundation for installing material. There is no shrinkage at all, and there will be no changes in geometry yet. A fence made of such piles can last a very long time. now synthetic materials are increasingly used, and polycarbonate sheets are in incredible demand.
The final version of the fence will be more expedient to do at the end of the construction of the main object.
There will remain material that can be used for this purpose. It will be easier to buy it a little more than pay for the project in full. You can only save on the optimization of certain operations, the exact amount of material, but not on quality. If all the conditions for construction are fulfilled, a fence made of screw piles can serve property owners for more than one year.
