Under reamed pile dwg foundation free download plugin
Well, engpocket friends must have been waiting for this post. After a few weeks ago we discussed the chicken claw foundation and stone foundation, this post will majorly discuss about how to draw under reamed pile dwg foundation quicker and easier than you have ever imagined.

This under reamed foundation dwg is hard to draw, we know, that is why we create this free plugin so all of you can use them free every time, everywhere. This will be the breakthrough in the civil drafting ways.
What is the under reamed pile foundation??
Under reamed pile foundation is a tubular shape foundation planted deep into the ground. The structure consists of a circular reinforcement cage (rebar) encased in cast concrete shaped into a tube or cylinder.
That is why the under reamed pile dwg have the concrete blocks around the rebar.
There are 2 ways to make an under reamed pile foundation, they are bore pile & strauss pile. The difference is:
1. Strauss Pile (Manpower drill)
This under reamed pile type often used for 2-3-residential houses or shophouses foundation.
- How it works: using a simple drill tool rotated with human power which usually consists of at least 2 people.
- The diameter is small, about 20 cm, 25 cm, up to 30 cm.
- The average depth is 6 meters to 10 meters.
- The characteristics of strauss pile foundation is on the bottom of the hole usually foriming a bulb / Under-reamed to strengthen the bearing capacity preventing the foundation from sinking.
2. Bore Pile (Drill machine)
This under reamed pile type used for heavier building loads or if the hard ground is very deep.
- How it works: Using the machine. There are two popular types of machines:
- Mini Crane: small diesel engine with three foot tower. Suitable for luxury housing or 4-5-buildings.
- Big Crane (Rotary Rig): Big machine. Used for skyscrapers or bridges.
- The diameter is large, ranging from 30 cm, 40 cm, 60 cm, even more than 1 meter.
- Depth up to 20 meters or more.
- Its characteristics are usually straight from top to bottom (without bulb), relying on ground friction and end resistance.
Advantages and field challenges of bored pile foundations
Why are bored pile foundations often the primary solution in densely populated areas or other major cities? The answer is because in the minimal vibration and noise levels generated during the construction process.
Unlike driven piles, which are hammered into the ground using hydraulic or diesel hammers, the boring method is much friendlier and safer for neighborhood structures. By using this method, the risk of complaints due to cracked walls or broken glass in nearby houses can be significantly minimized.
Critical quality control and stability
Nevertheless, on site quality control must be extremely strict because the concrete pouring process occurs underground and out of direct sight. One of the main points to the quality of a bored pile is the borehole wall collapse before the concrete is poured.
For unstable or sandy soil conditions, the use of temporary casing or bentonite slurry is crucial to maintain hole stability and prevent landslides within the shaft. Critical customers often ask for witnessing the pouring process firsthand to ensure integrity.
The importance of cleaning” and load bearing
The process of cleaning the bottom of the hole (cleaning) to remove residual drilling mud is a must and must be done perfectly. If residual mud remains at the bottom:
- The concrete will not seat properly on the hard soil (end bearing).
- This can lead to significant building settlement (sinking) in the future.
Streamlining the design process
With the help of our plugin of cad block under reamed pile above, we aren’t just assisted in drawing the cylindrical dimensions, we can also visualize the spiral reinforcement details and rebar dowels that will eventually connect to the pile cap.
This graphical efficiency will instantly speed up the approval process for the shop drawings you submit for our projects.
We also provide free plugins for ducting cad block & duct fittings, concentric reducer flat pattern, and HVAC diffuser cad block. Check them out. You guys can also watch the tutorial videos on our YouTube channel. Do not forget to like and subscribe
