Geotextile Filter Clogging: Prevention and Corrective Measures
Engineering answer
The clogging of the fabric cannot simply be attributed to the fact that the jacket is too heavy. The migration of fine particles leads to mechanical clogging, chemical deposition of iron or hard water, the formation of nutrient-rich water bioluminescence, and different processing paths. The design phase requires the use of soil-type matching perforations and penetrations, and the installation of repairable conduit drains; construction prevents dirt, concrete fillers and fillers from directly contaminating the fabric.

Key parameters and quick judgement tables
| Type of blockage | Identifying features | Directions of processing |
|---|---|---|
| Mechanical blockages | The earth's surface is covered with sediment, and the flow of water is gradually decreasing. | Re-shooting/replacing and repairing the coating |
| Chemical deposition | The crystal, iron orange hard rock | Water quality analysis and purification |
| Bioclocking | The glue, the smell | Control of nutrients and bio-cleaning |
| Construction pollution | Local cement or oil sludge | Local replacement, isolation of sources of pollution |

Acceptance points and common risks
- High pressure brushing without controlThe first is that the earth is made of a single layer of material, which can be torn apart or removed to form a hole.
- Acid washing incompatibility testingThe resulting polymer or downstream structure is damaged.
- Just change the cloth and don't change the soil.The clogging occurs again when the hole and the soil do not match.

Steps to landing
- Measuring water flowBuilding the front and back pressure and drainage capacity of the blockage.
- The sample identificationThe first is the water and the fabric.
- Testing and cleaningSmall-scale verification of the compatibility of physical or chemical cleaning.
- Correction of systemsAdding a layer of layering or repairing the entrance if necessary.
