Three-dimensional composite drainage network is a commonly used material in landfill, subgrade, tunnel, retaining wall and other projects, which can solve the problems of groundwater drainage and soil stability. So, will it suffer from loss during use?
1. The relationship between material properties and loss
1、Three-dimensional composite drainage net is composed of three-dimensional plastic net bonded with water-permeable geotextile on both sides, so it has good drainage performance and tensile strength. However, any material may be affected by various factors during use, resulting in loss.
2、Material aging is one of the main reasons for the loss of three-dimensional composite drainage network. When exposed to sunlight for a long time, ultraviolet radiation will cause photooxidative decomposition reaction of high molecular polymers, resulting in a decrease in material strength and performance. Temperature changes, bioerosion and chemical erosion, among others
Factors may also accelerate the aging process of materials.
2. Application scenarios and loss degree
1、The application scenarios of three-dimensional composite drainage network are diverse, and the degree of loss in different projects is also different. In landfills, its loss may be relatively rapid due to long-term immersion of leachate and microbial erosion. In projects such as roadbed and tunnel, although
It will also be affected by groundwater and soil pressure, but the depletion degree is generally small.
2、Improper operation during construction may also lead to the loss of three-dimensional composite drainage network. For example, over-stretching, folding Stack Or twisting may damage the structure of the material and affect its drainage performance and tensile strength.
3. Causes of loss and preventive measures
1、Choose high-quality materials: Choose high-quality three-dimensional composite drainage net with good anti-aging performance and strong corrosion resistance, which can prolong its service life.
2、Reasonable design: According to the specific engineering requirements and environmental conditions, rationally design the layout and structure of the drainage system to reduce the stress and pressure on the materials.
3、Standardized construction: During the construction process, operating procedures should be strictly observed to avoid unnecessary damage to materials. It is also necessary to strengthen the quality monitoring and acceptance work during the construction process to ensure the construction quality.
4、Regular maintenance: The three-dimensional composite drainage network that has been put into use should be maintained and inspected regularly to discover and deal with potential problems in time.
It can be seen from the above that the three-dimensional composite drainage network does have certain losses during use. By selecting high-quality materials, reasonable design, standardized construction and regular maintenance, the loss of materials can be reduced and its service life can be prolonged.
