Winter freeze-protection measures for Sichuan's impermeable geotextile membranes
Release date:
2020-10-27
As the saying goes, "Practice in the coldest days of winter—San Jiu—and in the hottest days of summer—San Fu." However, for construction companies, especially Sichuan Zigong Waterproof Geomembrane In winter, more detailed considerations become essential. If non-professionals attempt construction without meeting the necessary conditions, it can lead to human-induced damage to the geomembrane, compromising its durability and causing various other issues. Generally speaking, we need to pay close attention to factors such as the day’s temperature, wind speed, and even the possibility of rain. Below, we’ll outline some critical frost-prevention measures you can implement during the construction process:
1. Can raise soil temperature, helping to prevent Sichuan Zigong Waterproof Geomembrane Freeze-thaw damage occurs. Temperatures should generally be around 0 degrees Celsius. Sichuan Zigong Waterproof Geomembrane Under low-temperature conditions, the geomembrane should be kept taut, while under high temperatures, it should be allowed to relax. Additionally, installing an insulation layer beneath the geomembrane—such as polyethylene foam boards or polymer-based impermeable and insulating rolls—can effectively reduce and prevent frost heave in the canal foundation soil. This method is easy to implement and delivers noticeable results.
2. Replace the channel bed soil. Use gravel and sand to replace the highly frost-heave-prone soil in the channel bed. The depth of replacement varies depending on the soil characteristics and groundwater recharge conditions, but it should generally exceed 60% of the frost penetration depth. However, for long channels with large replacement volumes, this method requires significant engineering effort and leads to a corresponding increase in investment.
3. Wind speed should be below level 4. Construction should not proceed in winds of level 4 or higher, as well as during rain or snow, when temperatures are too low. In high-wind conditions, when wind forces become a factor, Sichuan Zigong Waterproof Geomembrane During construction, the HDPE geomembrane to be joined must be pressed against the aged woven kang bags.
4. Install a drainage system. When planning the channels, ensure that the channel bed remains at least as high as the groundwater table and is no less than the depth of the frost-prone soil layer. Additionally, route the channels through areas with excellent drainage properties, such as sandy gravel zones, and keep them well away from irrigated farmland and other water sources. To enhance the density of the channel foundation soil, employ compaction techniques—either by rolling or dynamic compaction—to increase soil density, thereby minimizing and neutralizing frost heave in the subgrade. This is a straightforward and practical measure, though the compaction depth must reach the full depth of the frost-prone soil layer.
After reading the above content, we believe you now have a better understanding of Sichuan Zigong Waterproof Geomembrane You now have a general understanding of how to effectively prevent freezing during winter. If you’re handling the construction yourself, you may encounter various challenges such as foundation preparation, laying, and welding. Don’t hesitate to reach out—we offer free assistance to help you tackle these issues. With our dedicated construction and after-sales team, including expert technicians in leveling, installation, and welding, we can efficiently meet all your geotextile and geomembrane waterproofing needs.
