forced drainage system的意思|示意

The forced drainage system is a method of underground drainage used mainly in arid or semi-arid areas. It is designed to increase the water flow rate of a drainage system so that more water can enter into the soil and the groundwater supply can be increased.

The forced drainage system works by introducing a pipe or a void between the surface and the underground drainage system. This pipe or void creates a pressure inside the drainage system. This pressure is then used to force water through the subterranean layers of the earth, allowing it to reach the deeper layers of soil and the underlying groundwater supply.

The forced drainage system is usually installed in areas where water is scarce, or where the amount of rainfall is insufficient to provide a natural drainage system. It can also be used to help reduce land subsidence.

To properly install a forced drainage system, the soil must first be tested to ensure it is suitable for the installation. The area must also be free of any large rocks or debris that could block the pipe or void. After the ground is prepared, the pipes or voids must be installed at specific distances and locations to ensure that the pressure created by the force is adequate to break down the soil and direct the water where it is needed.

Once the forced drainage system is installed, it must be maintained. This includes regular inspections and repairs. It is also important to ensure the pipes are not blocked by roots, debris, or other blockages.

The forced drainage system can be an effective way to improve underground water flow and increase the amount of water available to a dry or semi-arid area. While it can provide a useful solution to water scarcity, it is important to ensure that the system is properly installed and maintained to ensure it is effective at providing water.
