1.Plastic blind ditches are connected by nail-like hooks. The nail hook is made of ￠3 - ￠5 stainless steel wire. 2.The plastic blind ditch filter membrane has been sewn and wrapped on the blind ditch material at the time of supply. In addition, the joint can be wrapped with a strip filter memb...
Types of geomembranes 1. HDPE geomembrane, high-density polyethylene geomembrane, stable chemical properties, low-temperature resistance and aging resistance, the service life of up to 30 to 50 years, mainly used in a municipal solid waste landfill, solid waste, slag plant, sewage treatment plan...
At present, many engineering teams have independently changed the original plan of using the drainage board, thinking that the expected drainage effect could not be achieved. The drainage board manufacturer believes that this has a great relationship with the use method of drainage board. If the...
There are many kinds of geogrid, which can be divided into unidirectional geogrid, bidirectional geogrid, steel-plastic geogrid (for mining), glass fiber geogrid and warp knitting geogrid. Use of uniaxial geogrids: Unidirectional geogrids is a kind of high strength structural material, which is ...
The Difference between Geomembrane and Composite Geomembrane
1. Riveted and plugged geocells require metal parts when connecting. After the geocell is buried in the foundation, the metal parts are easily corroded, which affects the strength of the cell and greatly reduces the service life of the product. 2. The welded geogrid chamber avoids the use of met...
How to Distinguish Geocell from Grass Grid? Geocell（Picture1） Geocell is a kind of reinforced HDPE sheet material. It is welded with high strength to form a three-dimensional mesh cell structure. When a single geocell is deployed, it is a rhombic structure. However, people habitually ref...
1. A composite drainage network is normally laid between the foundation and the subsoil, mainly to reduce water accumulation. This method not only shortens the drainage time but also reduces the use of selected foundation materials and greatly increases the service life of the road. 2. The layin...
Application of The geocell (2) 4.It can be used for Subgrade in permafrost area. When filling roadbed in permafrost area, the minimum filling height should be reached. This prevents frost boiling or lowering the upper limit of the frozen layer. It can effectively prevent excessive settlement of ...
Application of The geocell (1) 1.It can be used to treat semi-filled and semi-excavated roadbed. When building embankments on slopes with a natural gradient of 1:5, steps should be excavated at the base of embankments. And the width of step should not be less than 1M. When constructing or rebuil...
