Composite drainage nets are of course very common in our lives. Because its advantages are more prominent, so there are more people who choose to use it. Today, I also take this opportunity to introduce you to relevant information about it? If you want to know, come and take a look.

We need to know a lot of basic information before using the composite drainage network. After all, there are many knowledge points involved. For example, in fact, the composite drainage network (also known as three-dimensional geotechnical drainage plate, tunnel drainage plate, drainage plate) is mainly composed of three-dimensional plastic mesh and double-sided bonded geotextile, which can replace the traditional sand and gravel layer, and is mainly used for landfill Drainage of fields, roadbeds and inner walls of tunnels. When using a composite drainage network, what we need to know is that in railways, highways and other transportation infrastructure, the safety and service life of the project is closely related to its own drainage system, of which geosynthetics are an important part of the drainage system. In addition, this composite drainage network is a new type of drainage geotechnical material. It is made of high-density polyethylene (HDPE) through a special extrusion molding process and has a special three-layer structure. The intermediate steel bars are rigid steel bars arranged longitudinally to form a drainage ditch. The cross-arranged steel bars up and down form a support to prevent the geotextile from being embedded in the drainage channel, and maintain high drainage performance even under high load. The combined use of double-sided viscous permeable geotextiles has the comprehensive performance of "reverse filtration-drainage-ventilation-protection", and is currently an ideal drainage material.

The composite drainage network is mainly used in drainage projects such as railways, highways, tunnels, municipal engineering, reservoirs, and slope protection, and the effect is remarkable. The product is characterized by strong drainage capacity (equivalent to one meter thick gravel drainage). High tensile strength. In addition, the composite drainage network reduces the possibility of geotextile embedded in the mesh core and maintains long-term stable drainage. Long-term bearing high pressure load (can bear about 3000ka compressive load). Corrosion resistance, acid and alkali resistance, long service life. The construction is convenient, the construction period is shortened, and the cost is reduced. The non-woven geotextile of the composite drainage network has an apparent pore size of 0.18mm, a water permeability of 0.26sec-1, a permeability of 0.2cm/sec, a breakdown strength of 580n, a trapezoidal tear strength of 356n, and a grip tensile strength of The strength is 900N. Its holding tensile strength is 50%, and its burst strength is 2750kpa. The carbon black content of the composite drainage net core is not less than 2%, and the density is 0.94g/cm3. When used, the tensile strength is not less than 36.5kn/m, the melt index is 1.0g/10min, and the thickness is 7.6mm. As the main product of our factory, we would like to thank new and old customers for their strong support. While ensuring the reliability of product quality, we will benefit our customers. If you have any technical questions about products, you can come here for consultation at any time. .

After the introduction of the above content, I don’t know if you have a basic overview of the composite drainage network. If you still don’t understand it, please call for detailed inquiries. Hope it will be helpful to those concerned.
