In engineering, Three dimensional composite drainage network It is a commonly used material, which has a unique three-dimensional space structure and very good drainage performance.
1. Three-dimensional Composite drainage network Advantages of
1、Excellent drainage performance: The three-dimensional composite drainage net is made of high-density polyethylene ( HDPE） As raw materials, it is processed through special processes. Its three-dimensional space structure can provide great drainage channels, so its drainage performance is far better than that of traditional materials. It has strong drainage capacity, high long-term stable hydraulic conductivity, and a displacement capacity of 20-200 cubic centimeters per minute, which can shorten the drainage time and reduce the risk of water immersion of the foundation.
2、Excellent load-bearing capacity: The three-dimensional composite drainage net not only has good drainage performance, but also has a very high load-bearing capacity. Its mesh core structure is strong and can withstand about 3000 kPa The compressive load can maintain stable drainage performance even under heavy load conditions. Its tensile strength and shear strength are also high, and it is suitable for various complex geological conditions.
3、Good durability and weather resistance: The three-dimensional composite drainage net is made of high-density polyethylene and other high-quality materials, which is corrosion resistant, acid and alkali resistant, and wear resistant, and can maintain stable performance in various harsh environments. It has a long service life, can reduce the frequency of replacement and maintenance, and reduce engineering costs.
4、Convenient construction and cost reduction: The three-dimensional composite drainage network adopts the form of coiled materials, which is easy to lay and transport. It is convenient to construct, can greatly shorten the construction period and reduce the construction cost. It has excellent drainage performance, which can reduce the workload of foundation treatment and reduce engineering costs.
5、Excellent comprehensive performance: The three-dimensional composite drainage network not only has drainage function, but also has comprehensive properties such as anti-filtration, ventilation, and protection. Its upper and lower cross-arranged ribs can prevent the geotextile from being embedded in the drainage channel, and can maintain the long-term drainage effect. Its raised core layer can also isolate the ground base layer and the covering layer materials, which can reduce problems such as capillary water rise and foundation settlement.
2. Disadvantages of three-dimensional composite drainage network
1、Weak anti-jacking ability: Because the thickness of the three-dimensional composite drainage net is relatively thin, its anti-jacking ability is poor. During the laying process, it is necessary to ensure that there are no excessively large sharp objects on the base surface, so as to prevent the top from piercing the overlying anti-seepage geomembrane and affect the overall waterproofing effect.
2、Limited water purification capacity: Under high flow rate conditions, the interception ability of the three-dimensional composite drainage network to suspended substances in the water quality will decrease, which will lead to a decrease in the water purification effect. Therefore, where high water quality requirements are required, it should be used in combination with other water treatment measures.
3、High construction requirements: The construction method and technical requirements of three-dimensional composite drainage network are relatively high. Professional technicians are needed to operate, so as to ensure the construction quality and drainage effect. Extra attention should also be paid to the details during the construction process, so as to avoid the cracking or damage of the drainage net.
4、High maintenance cost: Although the three-dimensional composite drainage network has a long service life, it is necessary to maintain it regularly if you want to ensure its normal use effect. Maintenance costs include labor costs, material costs and equipment costs, which will increase the overall cost of the project to a certain extent.
It can be seen from the above that the three-dimensional composite drainage network has the advantages of very good drainage performance, excellent bearing capacity, good durability and weather resistance, and can be used in the fields of civil engineering, environmental engineering and transportation construction. However, its shortcomings such as weak anti-jacking ability, limited water purification ability, high construction requirements and high maintenance cost also need attention. In practical application, it is necessary to make reasonable selection and design according to specific engineering requirements and environmental conditions, so as to give full play to its advantages and overcome its shortcomings.
