In engineering, the efficiency of drainage system can be related to the safety and durability of the engineering. Three dimensional composite drainage network It is a commonly used material in major projects, so what are its advantages?
1. Three-dimensional Composite drainage network overview
The three-dimensional composite drainage net is made of plastic net with three-dimensional structure bonded with water-permeable geotextile on both sides. It is formulated in high density polyethylene ( HDPE） As raw material, it is processed by special extrusion molding process, and has three layers of special structure: the middle ribs are rigid and arranged longitudinally A drainage channel; The upper and lower cross-arranged ribs form a support, which can prevent the geotextile from being embedded in the drainage channel, and maintain efficient drainage performance even under high loads.
2. Advantages of three-dimensional composite drainage network
1、Efficient drainage performance: The three-dimensional composite drainage network has strong drainage capacity, and its drainage performance is equivalent to a gravel layer with a thickness of one meter. The drainage channel formed by the middle ribs can quickly discharge groundwater or surface water, which can prevent the damage of accumulated water to the engineering structure.
2、High strength and stability: It has high tensile strength and shear strength, and can withstand long-term high-pressure loads without deformation. The design of the three-dimensional structure can not only enhance the overall stability of the material, but also reduce the probability of geotextile embedding into the mesh core, ensuring long-term stability Constant hydraulic conductivity.
3、Corrosion resistance and long life: The three-dimensional composite drainage net is made of high-density polyethylene material that is corrosion-resistant, acid and alkali-resistant. It has a long service life and can maintain stable performance in various harsh environments.
4、Convenient construction and cost-effective: Compared with the traditional sand and gravel layer drainage system, the construction of three-dimensional composite drainage network is more convenient and faster, which can shorten the construction period and reduce costs. Moreover, its drainage performance is very good, which can reduce the amount of foundation materials used and further reduce the project Cost.
5、Versatility: The three-dimensional composite drainage net not only has drainage function, but also has anti-filtration, ventilation and protection functions. It can isolate different soil layers to prevent soil loss, and it can also protect the foundation and drainage system from the external environment.
3. Application
Three-dimensional composite drainage network can be used in railways, highways, tunnels, municipal engineering, reservoirs, slope protection and other fields.
1、In railway subgrade and pavement drainage engineering, three-dimensional composite drainage network can drain groundwater, prevent subgrade softening and prolong the service life of roads;
2、In tunnel engineering, it can discharge mountain seepage water in time and protect tunnel structure from water damage.
It can be seen from the above that the drainage performance of the three-dimensional composite drainage network is very good. It can not only improve the efficiency and stability of the drainage system, but also reduce the engineering cost and maintenance difficulty.
