What are the characteristics of waterproof board

The waterproof board HDPE waterproof board (new HDPE waterproof board) used for underground anti-corrosion and anti-seepage projects adopts three-layer co-extrusion technology, adopts the world's advanced automatic geotextile production equipment and low-pressure high-density polyethylene raw materials, carbon black, anti-aging Agents, antioxidants, UV absorbers, stabilizers and other auxiliary materials compounded by formula on the basis of ordinary waterproof boards. This production line is highly automated. From order entry, formula, feeding, processing to quality monitoring, fully automatic computer control, strictly in accordance with scientific data operation. It can also use advanced raw materials (with super tensile strength), such as Metallocenence and traditional PE, EVA, LLDPE, etc.

What are the functions of composite drainage network?

What are the functions of composite drainage network?

Composite drainage net has unique advantages of low price, light weight, convenient maintenance and repair. So it is very popular with everyone. In fact, when in use, a composite drainage net should be laid between the foundation and the sub-base to drain the accumulated water between the foundation and the sub-base, block the capillary water, and effectively integrate it into the edge drainage system . This structure automatically shortens the drainage path of the foundation, so its drainage time is greatly shortened, and it can reduce the use of selected foundation materials (ie, finer and less permeable materials can be used). It can prolong the service life of the road. When using the composite drainage network, we also need to know that in the northern climate, laying the drainage network can help reduce the impact of frost heave. If the freezing depth is very deep, a geonet can be laid in a shallower position of the subbase as a capillary plug. In addition, granular subbases that are less prone to frost heave and extend to freezing depths often need to be replaced. The backfill soil that is prone to frost heaving can be directly filled on the drainage pipe network. In fact, it also reaches the ground baseline during operation. In this case, you will find that the system can actually be connected to a drain that brings the water table to or below this depth. This may limit the development of ice crystals, which is not necessary to limit traffic loads when ice melts in colder regions in the spring.

Geocell

Geocell

A geocell is an engineering structure used for soil improvement and soil and water conservation. It is usually composed of geotechnical materials, such as geotextiles, geonets and geomembranes. The main function of geocells is to increase the shear strength and stability of the soil and prevent geological disasters such as soil erosion and landslides. The characteristics, application and construction process of geocells will be introduced in detail below.

Rough surface HDPE geomembrane

Rough surface HDPE geomembrane

Rough HDPE geomembrane, that is, high-density polyethylene geomembrane, is a kind of anti-seepage material commonly used in engineering construction. It has a certain rough texture, which can increase the friction with other materials and improve the stability and anti-slip performance of the geomembrane. The following will introduce the characteristics, application fields and construction precautions of the rough HDPE geomembrane.

Composite drainage network

Composite drainage network

Composite drainage network is a drainage system that comprehensively utilizes various drainage technologies. It combines artificial drainage system and natural drainage system to form a complete drainage network. Its purpose is to solve urban drainage problems, reduce flood disasters, and improve water resource utilization efficiency in the process of urbanization.
