Before using the drainage network, there are also a lot of knowledge points that need to be mastered by everyone. This product mainly refers to the three-dimensional structure of the plastic mesh double-sided adhesive permeable geotextile, which can replace the traditional sand and gravel layers when used. , mainly used as drainage materials in landfills, roadbeds and inner walls of tunnels. Moreover, the characteristics of this drainage network are relatively clear, mainly reflected in that when the load is 720kPa and the gradient is 2%, the permeability is 2500m/d and the flow rate is 13pm/m.
The creep test retains more than 60% of its thickness after bearing a load of 1200kPa for 10,000 hours. The products produced by our company all meet these basic characteristics. If you need it, you can come here to buy it. Moreover, the carbon black content of the drainage mesh core is not less than 2%, the density is 0.94g/cm3, the tensile strength is not less than 36.5kN/m, the melt index is 1.0 g/10min, and the thickness is 7.6mm. In the future, when you choose, you must also satisfy these basic advantages. We are a new technology enterprise specializing in the R&D, manufacturing and system solutions of water conservancy, environmental governance and ecological restoration engineering materials. Welcome to call to choose the product that suits you.
The drainage network is laid between the foundation and the bottom, and the pumping between the foundation and the bottom. Performance This economic structural analysis can greatly reduce drainage time by automatically reducing the drainage path of the foundation of the enterprise, reducing the amount of selected foundation research materials used (which can be performed using more detailed and less permeable materials). Can prolong the life of the road. 2. Laying a drainage net on the sub-base can prevent the sub-base material from entering the ground layer (that is, isolation). The aggregate base layer enters the upper layer of the earthwork mesh to a limited extent. In this way, the composite geo-drainage grid has the potential effect of restricting the lateral development and movement of the aggregate, and by using this teaching method, it plays a similar role to the reinforcement technology of the geogrid. Generally speaking, the tensile strength and stiffness of composite geodrainage nets are superior to many geogrids used for foundation reinforcement, and these limitations increase the bearing capacity of the foundation.
If we have the conditions, we can prepare an empty workshop. If not, you need to prepare rainproof cloth, sunscreen and other materials. After the composite drainage nets we made are stacked neatly, don’t put them near fire sources or in sharp places, and then cover them with dark plastic sheets or sunscreen nets to prevent our composite geotechnical drainage nets from being exposed to direct sunlight. Also be careful not to store it at too low a temperature, otherwise it will easily become brittle, causing unnecessary loss and accumulation
As the name suggests, the composite drainage net is a composite geotechnical material made of a finished geotextile base fabric and a cooling three-dimensional drainage net core through a special process. The raw material of the net core is different from that of geotextile, but it is roughly the same as that of grass-proof cloth and drainage board. The geotextile here is a pointer-punched nonwoven fabric, which is divided into short silk cloth and long silk cloth.
