The
foundation is the foundation of any structure, especially houses, barns, or
utility buildings. Properly calculating a screw pile foundation is key,
affecting the durability and stability of the entire structure. In this
article, we'll cover the basic steps to help you correctly calculate a screw
pile foundation.
Why Choose Screw Piles?
Screw piles
are becoming increasingly popular due to their unique properties:
• Ease of
installation.
• High
load-bearing capacity.
• Works in
difficult soil conditions.
• No
concrete work required.
•
Environmentally friendly process.
All these
factors make screw piles an ideal choice for fast and reliable construction.
Steps for Calculating a Screw Pile Foundation
Calculating
a screw pile foundation involves several stages:
• Assessing
soil characteristics.
•
Determining the foundation load.
• Selecting
the number and depth of piles.
• Design
development.
Let's take
a closer look at each of these steps.
Assessing Soil Characteristics
First, you
need to conduct a geological survey. This will help you determine:
• Soil type
(sand, clay, loam, etc.).
•
Groundwater level.
• Soil load-bearing
characteristics.
This data
will help you estimate the load the piles can support and the depth to which
they should be driven.
Determining the Foundation Load
The next
step is calculating the load the foundation will support. This includes:
• The weight
of the structure itself.
• The
weight of furniture and equipment.
•
Additional loads (snow, wind, etc.).
Add up all
the loads to get a complete estimate of how much weight the structure must
support.
Selecting the Number and Depth of Piles
Once you know
the loads and soil characteristics, you can proceed to selecting the number and
depth of piles:
• For
lightweight structures (utility buildings, small sheds), 4-6 piles are
typically used. • For heavier structures (dachas, houses), the number of piles
can increase to 8-12.
• The depth
depends on the soil type and can vary from 1.5 to 3 meters.
It is also
recommended to consider the distance between piles, which is typically 2-3
meters.
Working with the project
Once all
the characteristics and parameters have been determined, you can begin
developing the foundation design. It is important to consider all the details
to avoid installation errors:
• Pile
placement diagram.
•
Installation requirements.
• Calculation of required materials.
If
necessary, engage professionals to adjust the plan.
