Reinforced microphone pad refers to a geosynthetic material composed of polypropylene geomat combined with steel wire mesh of a certain arrangement shape, which is a kind of lightweight protective material for slope surface. The reinforcement mesh with high tensile strength combined with the perfect erosion resistance of the geotechnical pad makes it have mechanical tension and stronger anti-erosion structure, so it is widely used in bank slope protection and ecological natural restoration in water conservancy, highway, railway, mining, municipal and environmental engineering.
Product Features:
The composition structure of the reinforced microphone pad itself combines the anti-erosion performance of the three-dimensional geonet pad and the characteristics of high strength and good durability of the double-twisted steel wire mesh, which is used for the erosion protection of the surface layer of the slope and the bank slope of the river, which can not only fix the topsoil to prevent soil erosion, but also promote the growth of vegetation and play a permanent role in the reinforcement of the vegetation roots, so as to achieve the greening goal more quickly.
In a nutshell, the main characteristics of the reinforced mic pad are as follows:
Vegetation
Due to the large number of voids in the reinforced microphone pad, the soil is not completely isolated from the outside world, and it can create favorable conditions for the flow of water and meet the conditions for vegetation growth. At the same time, due to the integrity of the reinforced microphone pad, it can provide additional stability for the root system of vegetation, seamlessly combine with vegetation, so that vegetation can have stronger resistance to wind and rain erosion, keep the slope in a better natural state, and effectively improve the ecological environment.
Self-permeability
The reinforced microphone pad has an open three-dimensional cavity structure, and the voids existing in the structure are conducive to the discharge of pore water in the soil below it, prevent the damage caused by hydrostatic pressure, and help to realize the consolidation of soft soil, so as to ensure the shear strength of the soil, so as to help realize the stability of the whole structure.
High intensity
The reinforced microphone pad not only retains the characteristics of fine holes and rough surface of the traditional microphone pad mesh, but also makes its overall strength larger because of the high strength of the double-twisted hexagonal metal mesh used in the skeleton.
Adaptable
The reinforced microphone pad is a flexible structure, which has a certain ductility, can well adapt to the terrain and landform where the project is located and is well combined with it, and will not produce structural joints, can well adapt to the deformation of the foundation, will not weaken the overall structure, is not easy to break and destroy, and the requirements for the construction site are relatively simple.
Others
In addition to the above characteristics, the reinforced microphone pad also has many advantages such as convenient construction, economy, long life and strong corrosion resistance, so it has great use value in practical applications.
Quality inspection control
The quality inspection of the reinforced microphone pad is first of all scientific testing of the whole, including the width, thickness, overall unit area quality, mesh size, nominal tensile strength of the reinforced mesh and polymer peel strength. In the selection of specific testing methods, we should not only consider the product itself, but also combine the specific requirements of the project for parameters and methods. For example, for the detection of polymer peel strength, 5 samples with a width of 102mm 2mm and a length of not less than 200mm can be evenly cut on the whole width of the sample according to the required direction and position, and the average value of the 5 samples is the final result.
Since the structural composition of the reinforced microphone pad mainly includes two parts: polymer and steel wire, in the quality control, in addition to the overall quality inspection of the product, the steel wire, steel wire mesh and polymer used should also be tested.
Reinforced mic pads are very corrosion-resistant, so they have a long service life of up to 40 years and 70 years. The length of the service life of the reinforced microphone pad is directly related to the quality of the steel wire used, and the 10% aluminum-zinc alloy steel wire is generally used. If the performance of steel wire strength and corrosion resistance can not meet the relevant requirements, it will lead to the service life of the reinforced microphone pad can not meet the expectations, and even have a serious impact on the protection project, so it is particularly important to strengthen the quality inspection of the steel wire used.
In view of the important role played by the steel wire in the overall structure, when the steel wire is tested, it is not only necessary to detect the technical parameters of the steel wire diameter, plating weight, aluminum content in the plating layer, etc., but also to test the steel wire related items before preparation according to the actual needs.
Steel mesh is indispensable as a skeleton, and the role of polymers in the whole reinforcement mat is equally important, which can play an important role in increasing the friction between the steel mesh and the site interface. As far as polymer testing in reinforced mic pads is concerned, there are many aspects such as polymer unit area mass and polymer density.
Conclusion
Considering the specific use environment, when the same product is used in different projects, the focus on its quality inspection may be different, and the requirements for specific parameters are also different, which needs special attention. However, no matter when, the quality inspection of the reinforced microphone pad is not a work that can be ignored, whether it is used in road and bridge engineering, or for mountain management, or embankment protection, etc., the quality inspection of the reinforced microphone mat must be strengthened, so that it can better play its due role.
