In engineering, drainage is one of the key factors affecting the quality and long-term stability of engineering. Geotechnical drainage networks and Composite drainage network They are two common drainage materials, each with unique advantages and applicable scenarios.
一. Material properties and structure
The geotechnical drainage net is made of polypropylene ( PP） Or high density polyethylene ( HDPE） Made of such polymer materials, it has the characteristics of light weight, corrosion resistance, and anti-aging. Its structure is mostly flat mesh, and the drainage channel is formed by criss-crossing ribs, which has very good water permeability and certain strength.
The composite drainage network is compounded by adding other materials (such as glass fiber, polyester fiber, etc.) on the basis of geotechnical drainage network through special processes. This structure not only retains the advantages of geotechnical drainage network, but also improves the tensile strength and compressive properties of the material, allowing it to withstand greater loads and more complex stress environments.
二. Drainage performance
The drainage performance of geotechnical drainage net and composite drainage net is very good. The geotechnical drainage network has a network structure, which can quickly introduce water into the underground drainage system and alleviate the problem of surface water accumulation. On this basis, the composite drainage network can optimize the design of drainage channel and improve drainage efficiency by adding composite materials. Especially when dealing with large amounts of standing water or requiring rapid drainage, composite drainage netting can be used.
三. Service life and maintenance costs
1、The service life of geotechnical drainage network mainly depends on the material quality and construction environment. Under normal circumstances, it can last for several years or even longer. However, in harsh environments (such as high temperature, high humidity, strong ultraviolet rays, etc.), the performance of geotechnical drainage networks may gradually decline, so they should be checked and replaced regularly.
2、Composite drainage net has higher weather resistance and durability due to the addition of reinforcement materials. Under equivalent conditions, it typically lasts longer and is less expensive to maintain. The composite drainage net also has better tear and puncture resistance, and can withstand accidental damage during construction.
四. Construction convenience
In terms of construction convenience, both geotechnical drainage network and composite drainage network have good operability. Both can be cut and spliced according to the needs of the project, and the laying process is relatively simple and fast. However, the composite drainage network has heavy quality and high strength requirements, and may require more manpower and equipment support during laying.
五. Economic analysis
From an economic perspective, the price difference between geotechnical drainage networks and composite drainage networks mainly depends on material costs and production processes. Under normal circumstances, the price of geotechnical drainage network is relatively low, which is suitable for engineering projects with limited budget. However, when considering long-term benefits and maintenance costs, composite drainage networks are more suitable because of their high durability and low maintenance costs.
