Examining the structure of sewage wells and well drilling methods

Paying attention to the structure of the sewage well and observing the points related to its parts play an effective role in standard well drilling methods in the field of plumbing in Toronto. Adequate attention to the steps of draining the well and pouring lime into the sewage well is necessary and important for the repair measures of all types of sewage wells. Therefore, in this article, we will introduce the structure of the well and how to implement the mentioned processes.

Parts of the sewer well structure

  • well rod
  • Well pot
  • well collar
  • Well storage
  • concrete well slab

Well rod

One of the parts of the well is the cylindrical rod that determines the length of the rod. To dig a rod, it is necessary to pass the impermeable part, which is the clay, and reach the soil drain. The existence of coarser stones does not create a problem for sewage penetration, therefore, sand veins are the best drainage vein.

The depth of the well rod

The minimum depth for drilling a well rod is 12 meters, but factors such as the height of the warehouse, the location of the well, etc., have an effect on this depth. Paying attention to the depth of the rod is essential in drilling a well, because if a problem occurs, it can cause the building to settle and destroy it.

The important point in drilling a well is that the rod should be drilled vertically, and if we encounter an obstacle during the operation, it is necessary to change its location or remove the obstacle and continue drilling in order to prevent the deviation of the well path.

This obstacle can be a big rock in the way of the well rod, which is drilled if possible and the rod is still drilled vertically.

Well storage

Well storage refers to the tunnels that are dug at the bottom of the well, the volume of this tunnel is determined by the location of the well and the type of structure of the sewage well entering it.

Well collar

A brick is used to cover the well mouth, which is called a well collar. Bricklaying of the well opening is done in a conical and stepped manner at a distance of one to two meters from the well opening on the ground level.

The bricks are arranged in such a way that each vein is placed in front of the lower vein so that the mouth of the well is closed and only open as a small opening.

It is essential to use resistant mortar in the collar to prevent it from settling and save people’s lives.
