一. Structure and characteristics of composite wave drainage mat
The composite corrugated drainage mat is made of polymer (such as polypropylene, etc.) filaments interwoven by melting and laying process, forming a structure with fixed corrugated channels. Therefore, the drainage mat has very good pressure resistance, high opening density, multi-directional water collection and horizontal drainage functions. Some composite corrugated drainage mats also combine three-dimensional polypropylene mesh mats and non-woven geotextiles, which can form a three-dimensional drainage structure of anti-filtration, drainage and protection through thermal bonding. This composite structure can not only enhance the strength and durability of the drainage mat, but also improve its drainage efficiency and application range.
二. The main function of composite wave drainage mat
1、Efficient drainage
The wave structure of compound wave drainage mat can increase the tortuosity of water flow path, slow down the water flow speed and improve the drainage efficiency. The internal drainage channel design can quickly collect and drain groundwater or rainwater, reduce soil moisture content and prevent flooding. Therefore, it can be used in water conservancy projects, road construction, basement waterproofing and other fields.
2、Enhanced structural stability
The corrugated structure can increase the contact area between the drainage mat and the surrounding soil, improve the friction force and enhance the overall stability of the structure. Through drainage, the soil water content can be reduced, and the stability of foundation and slope can be consolidated. In the slope protection of highways, railways and other traffic trunk lines, the use of compound wave drainage mat can prevent slope collapse and soil erosion, and ensure driving safety.
3、Isolation and protection
The composite wave drainage mat can be used as an isolation layer between different materials to prevent mixing and pollution between different substances. In underground engineering, it acts as a waterproof layer to protect underground structures from moisture erosion. The drainage mat can also disperse and reduce the pressure of the upper load on the foundation, and improve the bearing capacity of the foundation.
4、Environmental protection and ecological restoration
In environmental protection projects such as ecological restoration and landfill, composite wave drainage mat can be used to isolate pollutants and promote ecological restoration. Its acid and alkali resistance and anti-corrosion properties allow the drainage mat to maintain stable performance in harsh environments, providing long-term and reliable drainage support for ecological restoration projects.
三. Application
1、In water conservancy projects such as reservoirs, dikes and river regulation, the use of drainage mats can prevent floods, protect dikes and stabilize riverbeds.
2、In the construction of transportation infrastructure such as expressway and railway, drainage mat can improve the stability and safety of slope
3、In waterproofing and drainage projects of underground structures such as basements and underground garages, compound wave drainage mats can also be used.
