Composite drainage network And PCR Seepage and drainage net mats are commonly used materials in engineering. So, what are the differences between the two?
Composite drainage network
1. Material composition and structural characteristics
1、Composite drainage network
The composite drainage net is made of plastic net with three-dimensional structure and permeable geotextile bonding on both sides. So, it has very good water conductivity and drainage ability. The composite drainage network is made of high-density polyethylene ( HDPE） As raw materials, it is processed by a special extrusion molding process and has three layers of special structure. The middle ribs are rigid and arranged longitudinally to form a drainage channel; The upper and lower cross-arranged ribs form a support that prevents the geotextile from being embedded in the drainage channel and maintains high drainage performance even under high loads.
2、PCR Seepage drainage net mat
PCR Seepage drainage net mat is a commonly used material in retaining wall drainage system. It is made of high-quality polymer material and has a unique network structure, which allows water to flow through quickly. It can also lock soil particles and prevent soil erosion. PCR The seepage drainage net mat not only has very good drainage performance, but also has very good soil retention and durability. Its materials can be recycled and reused, which conforms to the modern green building concept, and can reduce construction waste and protect the environment.
2. Functional application
1、Composite drainage network
Composite drainage network has very good drainage performance and structural stability, and is commonly used in drainage projects such as roads, bridges, water conservancy, railways, tunnels, municipal projects, reservoirs, and slope protection. It can quickly drain the accumulated water between the foundation and the base, block the capillary water, and can be combined into the edge drainage system to shorten the drainage path of the foundation and improve the supporting capacity and stability of the foundation. The composite drainage net can also prevent the subbase fines from entering the ground base layer, acting as an isolation and potentially limiting the lateral movement of the aggregate base layer, improving the overall performance of the foundation.
2、PCR Seepage drainage net mat
PCR Seepage drainage net mats are mainly used in retaining wall drainage, highway slope protection, railway subgrade drainage, roof greening and drainage, ecological restoration projects and other projects. It is capable of rapidly lowering the groundwater table, reducing the soil water content and improving the bearing capacity and stability of the foundation. Its network structure can effectively lock soil particles, prevent soil erosion and maintain ecological balance while draining water. PCR The seepage drainage net mat also has very good air permeability, which helps the gas exchange in the soil and promotes plant growth.
Seepage drainage net mat
III. Construction and maintenance
1、Composite drainage network
The construction of composite drainage net is relatively simple and easy to cut and lay. When laying, ensure that the laying surface is smooth and free of sharp objects, so as not to affect the integrity and use effect of the drainage net. Adjacent drainage networks should be overlapped and fixed to ensure smooth drainage. In terms of maintenance, it is necessary to regularly check the use of the drainage net, clean up blockages in time, and maintain its good drainage performance.
2、PCR Seepage drainage net mat
PCR The seepage drainage net mat is also very convenient during construction, and it is light in weight, easy to cut and lay, which can greatly reduce the construction difficulty and cost. When laying, ensure that the net mat is tightly combined with the soil to prevent soil erosion. It should also be laid according to the design requirements, and pay attention to the overlapping and fixing of the net mat to ensure smooth drainage. During maintenance, it is necessary to regularly check the use of the net mat, clean up the blockage in time, and maintain its good drainage and soil retention performance.
As can be seen from the above, the composite drainage net and PCR There are significant differences in material composition, structural characteristics, functional application, construction and maintenance of seepage and drainage net mats. Composite drainage network has very good drainage performance and structural stability, and is commonly used in various drainage projects; And PCR Seepage drainage net mat has very good drainage, soil retention and air permeability properties, and is commonly used in retaining wall drainage system. When selecting drainage materials, drainage materials should be comprehensively considered according to project requirements, material properties and construction conditions to ensure project quality and safety.
