Examining the structure of sewage wells and well drilling methods-part 2

As you know, in the previous part of this article, we explained the three main parts of the sewage well structure. Today we want to review the other parts together.

Well pot

The well pot is used to prevent the dispersion of wastewater entering the well and to direct this wastewater vertically to the end of the well. The importance of the existence of this pot in plumbing in Toronto is determined when the sewage in the well reaches the collar and washes its soil. In this way, the collar is settled and the well opening is opened. Therefore, by using a collar, you can protect yourself from these types of accidents.

Concrete well slab

As much as possible, the well should be dug vertically in low-traffic areas, because there is a high probability of pipes getting blocked in horizontal piping, and in high-traffic areas, there is a possibility of people falling.

Therefore, these incidents can be prevented by placing a concrete slab on the well pot.

Well drilling methods

Drilling a sewage well with a mechanical device

Drilling a sewage well with a mechanical device is one of the methods of digging a sewage well. In this method, mechanical energy is transferred to the rock using one of the three methods of percussive drilling, rotary drilling or a combination of the two. In terms, the operation that causes a hole to be dug in the rock by a mechanical method is called mechanical drilling. Today, 98% of excavations are done mechanically. In surface mines and semi-deep and deep excavations, rotary drilling machines with cone-shaped drills and heavy impact machines are mainly used; However, impact machines are used in underground mines or generally in underground operations.

Thermal well drilling

In general, regardless of the type of well drilling methods and the source of energy, the operation that leads to drilling a hole in the rock is called permeability. In the thermal method, with the help of thermal energy obtained by mixing air or oxygen with a type of fuel, preferably kerosene, penetration is done in the rock. Air or oxygen and fuel are sent from two separate ducts into a tank located behind the drill, and after ignition, the flame transfers heat to the surface of the rock through the nozzle of the drill head, and the heat makes the surface of the rock scalding and ready for separation. Finally, with the help of water pressure, the pieces are separated and moved to the ground.
