Dredging works

When coastal soil is washed away, sediments grow on the bottom – and this is a natural process. However, it is fraught with the fact that the reservoir may become unusable, because there will be too much organic waste. How to avoid it? There is such a rescue measure as dredging.

Dredging is a type of excavation work that is carried out on the bottom of a reservoir to deepen or lay waterways to ports, to build bridges, piers, lay pipelines and enlarge reservoirs.

Dredging operations are divided into 2 groups:

• Operational – if you need to clear a reservoir of various foreign objects;
• Capital – if it is planned to build hydraulic structures.

In both cases, dredging operations include a number of stages:

1. The actual depth of the object is checked and the amplitude of its changes is determined.
2. The sediment accumulation zone is analyzed;
3. The area is measured;
4. Equipment is being selected.

Most often, dredgers are used to deepen reservoirs, which are sucked into pre-loosened soil and then thrown onto the shore. This happens until the depth reaches the required parameters.

Why is dredging necessary?

1. To increase the cross-section of water flow in larger rivers and lakes. This will improve the maneuverability of low-draft vessels.
2. To rid the reservoir of bottom sediments and adjust the depth. If the reservoir has not been affected for several years, then it will be difficult to return it to its former state. And then it is worth resorting to the arrangement of the bottom and additional cleaning of the reservoir.
3. Dredging operations allow for a convenient approach to a pier located in water bodies with a sandy bed or with large silt deposits.

How often is dredging required?

In order for all indicators of the reservoir to remain at the required level, dredging operations should be carried out regularly. To do this, it is necessary to check the growth of the volume of bottom sediments, as well as the presence of sliding soil. The deposition of organic matter is also monitored, since it also reduces the depth of reservoirs.

Based on this, the frequency of bottom dredging is determined. This is a regular maintenance procedure for ponds, rivers and lakes. It extends the life of the latter, so do not neglect the pond dredging service.
