Fiberglass grid design In order to prevent reflection cracks in motor vehicle lanes, and to strengthen the pavement strength in special places such as bus stops and wells, it is necessary to increase the glass fiber grid. Lay a glass fiber grid be...

Option 1, a medium-low head earth-rock dam on a homogeneous or double-layer foundation, with a thick permeable layer and no strong permeable interlayer, has advantages in economy and construction period compared with the general vertical anti-seep...

Composite geotextile has the characteristics of good tensile strength, high impact strength, impermeability, acid and alkali resistance, heat resistance, weather resistance, and abrasion resistance. Impervious geotextiles are widely used in the co...

1. Technical indicators of composite geomembrane In order to effectively cut off the external moisture, the barrier adopts an anti-seepage composite geomembrane. During construction, in order to effectively protect the geomembrane and play its rol...

High-density polyethylene geomembrane is mainly used in garbage disposal sites, landscape lakes, and ponds. The rural grassroots level is laid flat, and the overall design of the membrane roof has the thickness of the protective layer, so the risk...

The so-called geogrid-reinforced retaining wall technology is to perforate a high-density polypropylene or polyethylene board and then heat it to stretch it in one or two directions. The purpose of this is to improve the directional arrangement of...

In the industrial production process, some waste liquid is often produced. Draining the waste liquid into an evaporation pond with an impermeable layer can not only avoid environmental pollution caused by the direct discharge of the waste liquid b...

Non-woven fabric is made of fiber mesh and consolidation. The fiber has a three-dimensional structure, good ductility, and mechanical properties. Different materials and processes can be used to design fabrics with a wide range of structural featu...

Technical requirements for geotextile connection 1. Technical requirements. Geotextiles are generally spliced by splicing, all splicing must be continuous, and spot welding is not allowed. Any “missing stitches” on the sewn geotextile ...

Artificial lakes usually have poor self-purification capacity, fragile ecosystem structure, and are easily affected by many uncertain external factors. Therefore, how to maintain a large area of ​​water at a certain level for a long time, ensure t...
