一. Three-dimensional Composite drainage network Material properties of
The three-dimensional composite drainage net is made of high-density polyethylene ( HDPE） Or polypropylene ( PP） Made of such polymer materials, it has the following material characteristics:
1、High strength and high modulus: The three-dimensional composite drainage network has high tensile strength and modulus, and can withstand large earth pressure and water flow impact.
2、Good weather resistance and corrosion resistance: It can resist the erosion of chemicals such as ultraviolet rays, oxidation, acids and alkalis, and has a long service life.
3、High water permeability: The internal structure of the three-dimensional composite drainage network has a large number of pores, which facilitates the penetration and discharge of water and can maintain the stability of the soil.
4、Good flexibility and plasticity: It can still maintain good flexibility and plasticity at low temperature, and adapt to the construction requirements of different geological conditions.
二. Working principle of three-dimensional composite drainage network
1、Drainage function: The internal structure of the three-dimensional composite drainage network can form a continuous drainage channel, allowing groundwater and seepage water to be discharged through the mesh, which can reduce the water pressure of the soil, reduce the weight of the soil and improve the stability of the soil.
2、Filtration function: The mesh structure of the three-dimensional composite drainage net can block the loss of soil particles, and also allow water to pass through to play a filtration role. Can keep the structural stability of the soil and prevent soil erosion.
3、Reinforcement: It can form a stress skeleton in the soil, which can enhance the bearing capacity of the soil and improve the overall stability of the soil.
4、Isolation effect: It can separate soils of different properties, prevent soils from mixing with each other, and maintain the original structure and properties of the soil.
三. Application of three-dimensional composite drainage network in engineering
1、Road engineering: In highways, urban roads and other projects, the three-dimensional composite drainage network can be used for subgrade reinforcement, pavement drainage, etc. to improve the bearing capacity and service life of roads.
2、Railway engineering: In high-speed railway, ordinary railway and other projects, it can be used for subgrade stability, slope protection, etc. to ensure the safe operation of railway lines.
3、Water conservancy projects: In flood control embankments, reservoir dams, channels and other projects, three-dimensional composite drainage networks can be used for embankment reinforcement, dam drainage, etc. to improve the safety and stability of water conservancy facilities.
4、Environmental protection projects: In environmental protection projects such as landfills and sewage treatment plants, it can be used for leachate collection, anti-seepage layer protection, etc. to prevent the spread of pollutants and protect the environment.
四. Improvement of engineering performance by three-dimensional composite drainage network
1、Improve stability: By enhancing the bearing capacity and stability of soil, it can reduce the occurrence of settlement and slip, and improve the safety of engineering structures.
2、Improve drainage performance: It can reduce the water pressure of the soil and promote water discharge, reduce the collapse and softening of the soil, and improve the stability and durability of the project.
3、Enhanced crack resistance: By improving the tensile strength and modulus of the soil, the generation and propagation of cracks are reduced, and the overall performance of the project is improved.
4、Improve construction efficiency: The three-dimensional composite drainage network is lightweight and easy to handle, which can shorten the construction period and reduce the construction cost.
5、Extended service life: Its weather resistance and corrosion resistance are very good, which can extend the service life of the project and reduce maintenance and repair costs.
It can be seen from the above that the application prospect of the three-dimensional composite drainage network is very wide, and it also has very significant performance advantages. Through reasonable design and construction methods, it can give full play to its role in improving engineering performance.
