1. Material composition and structural characteristics
1. Composite drainage net
The composite drainage net is made of a three-dimensional plastic net and a permeable geotextile bonded on both sides. Therefore, it has very good water conductivity and drainage capacity. The composite drainage net is made of high-density polyethylene (HDPE) as raw material, processed by a special extrusion molding process, and has a three-layer special structure. The middle ribs are rigid and arranged longitudinally to form a drainage channel; the ribs arranged crosswise up and down form a support to prevent the geotextile from being embedded in the drainage channel, and can maintain a high drainage performance even under very high loads.
2. PCR seepage drainage net mat
PCR seepage drainage net mat is a material commonly used in retaining wall drainage systems. It is made of high-quality polymer materials and has a unique mesh structure that allows water to pass quickly, and can also lock soil particles to prevent soil erosion. PCR seepage drainage net mat not only has very good drainage performance, but also has very good soil retention and durability. Its materials are recyclable and reusable, in line with the concept of modern green buildings, can reduce construction waste and protect the environment.
2. Functional Application
1. Composite Drainage Net
The composite drainage net has very good drainage performance and structural stability, and is often used in drainage projects such as roads, bridges, water conservancy, railways, tunnels, municipal engineering, reservoirs, and slope protection. It can quickly drain the accumulated water between the foundation and the subgrade, block capillary water, and can be combined with the edge drainage system to shorten the drainage path of the foundation and improve the support capacity and stability of the foundation. The composite drainage net can also prevent the subgrade fine material from entering the subgrade, play an isolation role, and potentially limit the lateral movement of the aggregate subgrade, thereby improving the overall performance of the foundation.
2. PCR Seepage Drainage Net Mat
PCR Seepage Drainage Net Mat is mainly used in retaining wall drainage, highway slope protection, railway subgrade drainage, roof greening and drainage, ecological restoration projects and other projects. It can quickly lower the groundwater level, reduce soil moisture content, and improve the bearing capacity and stability of the foundation. Its mesh structure can effectively lock soil particles while draining water, prevent soil erosion, and maintain ecological balance. PCR drainage mat also has very good air permeability, which helps gas exchange in the soil and promotes plant growth.
3. Construction and maintenance
1. Composite drainage net
The construction of composite drainage net is relatively simple and easy to cut and lay. When laying, make sure that the laying surface is flat and free of sharp objects to avoid affecting the integrity and use effect of the drainage net. Adjacent drainage nets should be overlapped and fixed to ensure smooth drainage. In terms of maintenance, the use of the drainage net should be checked regularly, and blockages should be cleared in time to maintain its good drainage performance.
2. PCR seepage drainage net mat
PCR seepage drainage net mat is also very convenient during construction, and it is light, easy to cut and lay, which can greatly reduce the difficulty and cost of construction. When laying, make sure that the net mat is closely combined with the soil to prevent soil erosion. It should also be laid according to the design requirements, pay attention to the overlap and fixation of the net mat to ensure smooth drainage. During maintenance, the use of the net mat should be checked regularly, blockages should be cleared in time, and its good drainage and soil retention performance should be maintained.
As can be seen from the above, there are significant differences between composite drainage nets and PCR seepage drainage net mats in terms of material composition, structural characteristics, functional application, construction and maintenance. The composite drainage net has very good drainage performance and structural stability, and is often used in various drainage projects; while the PCR seepage drainage net has very good drainage, soil retention and air permeability, and is often used in retaining wall drainage systems. When selecting drainage materials, the medicine is comprehensively considered according to the project requirements, material properties and construction conditions to ensure the quality and safety of the project.
