Yes under reamed piles are most suited for the black cotton soils.The upward stress ,when the soil shrinks would be taken care by the reamers.

Displacement piles are driven into the ground by displacing the soil, which can lead to increased soil density around the pile and typically results in higher load-bearing capacity. In contrast, non-displacement piles, such as bored or drilled piles, involve removing soil to create a hole and then filling it with concrete, which may not enhance surrounding soil density. Consequently, displacement piles are often preferred in situations where soil compaction is beneficial, while non-displacement piles are used in areas where soil disturbance needs to be minimized. Each type is chosen based on site conditions and structural requirements.

They are a means of building retaining walls.
piles
1. enlarged base (underream), also known as bell, which increases the base bearing capacity and load carrying capacity. 2. DECREASES THE VERTICAL SETTLEMENT AND DIFFERENTIAL SETTLEMENT. 3. IT ACT AS FOUNDATION FOR UNSTABLE AND COHESIVE EXPANSIVE SOIL SUCH AS BLACK COTTON SOIL. 4. The cost advantages of under-reamed piles are due to the reduced pile shaft diameter, resulting in less concrete needed to replace the excavated material. 5. Provision of under reamed bulbs has the advantage of increasing the bearing and uplift capacities. 6. It also provides better anchorage at greater depths 7. These piles are efficiently used in machine foundations, over bridges, electrical transmission tower foundation sand water tanks
Foundation footings on black cotton soil should be designed to accommodate the swelling and shrinkage properties of the soil. It is important to have a wider and deeper footing to distribute the load over a larger area. Proper drainage and moisture control measures should also be implemented to prevent water-induced swelling and structural damage.

After they died definitely. Piles and piles of corpses were disposed of in this way.

Usually they den up in caves, under tree stumps, or in piles of downed trees. Sometimes these dens may contain hundreds of rattlers, along with black snakes and copperheads.
Yes, piles of damp leaves and under overhanging plant leaves are regular haunts of frogs.
