If engineers encounter damaged geotextile plastic drainage boards during construction, do not waste them. They can be repaired, and the repaired geotextile can be reused. Perhaps our repair work after geotextile damage is not very professional. The following is a summary of relevant professional content based on comprehensive data
1. All geotextile sheets and joints must be inspected for defects. The geotextile sheets and seams must be clearly marked on the geotextile and repaired. Worn geotextile must be repaired by laying and hot connecting geotextile sheets, which are at least 200 millimeters longer than the defective edges in all directions. It is necessary to strictly control the thermal connection to ensure that the geotextile patch and geotextile are tightly bonded without damaging the geotextile.
2. Before the end of each day's laying, visually inspect all geotextile surfaces that are being inspected on that day to ensure that all damaged areas have been marked and immediately repaired, and that there are no foreign objects that may damage the laying surface, such as fine needles and small nails.
3. When repairing damaged geotextile, the following technical requirements should be met:
① The repair materials for repairing holes or cracks should be consistent with geotextile. The repair should extend at least 30 centimeters beyond the damaged geotextile
② At the bottom of the landfill, if the cracks in the geotextile exceed 10% of the coil width, the damaged part should be removed and two geotextile components should be connected; If the gap exceeds 10% of the coil width on the slope, the geotextile coil must be removed and replaced with a new coil.
In addition, geotextile has good filtration performance, which can filter out some impurities in water and soil. Therefore, in this engineering field, it can also be used in the engineering field of some Rivers and Lakes, so its application scope is relatively wide, but the main scope is limited to engineering, and it has corrosion resistance, so even if it is used in soils with different acid and alkali levels, it will not have any impact on it, so it can fully play its role.
