What is a drainage network? The drainage net is also called the earthwork drainage board, the tunnel drainage board, and the drainage water board. Drainage engineering materials for buried sites, roadbeds, and inner walls of tunnels.
What are the characteristics of the drainage network? Let's analyze it together.
1. The drainage net 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.
3. If the road is old, its cracks will cause most of the rainwater to enter the section. In this case of development, the drainage network can be laid directly under the road instead of the drainage foundation. Drainage network design allows moisture to be collected before it enters the social foundation/base. In addition, a layer of film can also be wrapped at the bottom of the drainage system pipe network to further prevent soil moisture from entering the Chinese ground.
For rigid road systems, the structure allows for a road design with a high drainage coefficient. Another advantage of this drainage network structure is that it allows for more uniform hydration of the concrete (research on this advantage is ongoing). The structural analysis can be carried out systematically by extending the life of roads, whether they are rigid roads or more flexible roads.
4. If the drainage network is laid under the climate and environmental conditions in the northern region, we can reduce the impact of frost heave. If the depth of freezing technology is deep, the earthwork net can be laid at the shallow position at the bottom of the process, and Moses can be used to prevent it.
In addition, it is often necessary to replace it with a grainy bottom that is difficult to freeze and extends down to freezing depths. White pens that are prone to freezing can be removed by filling the drain system pipe network directly up to the ground. In this case, the system can be connected to a drain outlet so that the water table is at or below that depth. In this way we can discover the potential to limit the development of ice crystals, so that springtime ice melts in cold regions without limiting the load on China's transportation system.
