1,Introduction

 

bentonite geotextile clayliner is composed of 3 levels. The upper level and the lower level are woven geotextile  and non woven textile. 

The middle level is bentonite grains, which are carefully selected crude and filled in between the two levels after special processing. 

The bentonite grain in GCL made by this method does not flow in a fixed direction. It distributes evenly and forms waterproof layer, owning excellent waterproof effect. 

 

2,Feature

(1) A permanent waterproof performance, and excellent water seepage performance, impermeability hydrostatic pressure up to 1.0MPa above, permeability coefficient 5 *10-9cm / s. Because the Department of Natural sodium bentonite inorganic materials, even after a long time or the surrounding environment changes, aging or corrosion does not occur.

 

(2) Has all the characteristics of geotextile material, such as separation, reinforcement, protection, filtration, simple construction and unrestricted construction environment temperature below 0 0 C also be construction. Just when construction GCL waterproof blanket tile on the floor, when the elevation or slope construction, with nails and washers to secure it, as required, can overlap.

 

(3) Easy to repair; Even after water (seepage) end of construction, such as waterproof layer accident damage, as long as the site of the damage to be a simple fix, can ever regain perfect waterproof performance.

 

(4)green: Bentonite is a natural inorganic material, harmless, non-toxic, no particular impact on the environment, with good environmental performance.


(5) simple construction period is short: and other waterproof materials, the construction is relatively simple, does not require heating and paste. Product width up to 6 meters, with international geotextile (film) to match the size, greatly improving the efficiency of construction.

 

(6) Integrated waterproof materials and objects: When sodium bentonite water, with 20-28 times the capacity expansion, even if the concrete structure vibration and settlement, bentonite GCL can repair cracks in the concrete surface less than 2mm.

Q:How are geonets used in earthwork?
Geonets are used in earthwork to provide soil stabilization and drainage. They are placed within the soil layers to enhance its strength and prevent erosion by distributing the load evenly. Additionally, geonets facilitate the efficient flow of water, preventing the accumulation of excess moisture in the soil, which can lead to instability.
Q:Are earthwork products suitable for underground parking structures?
Yes, earthwork products can be suitable for underground parking structures. These products, such as geotextiles and geomembranes, can provide effective solutions for erosion control, soil stabilization, and waterproofing systems. They can enhance the stability and durability of the underground parking structure, ensuring the safety and longevity of the facility.
Q:How do geosynthetic products contribute to stormwater management?
Geosynthetic products play a crucial role in stormwater management by providing effective erosion control, sediment retention, and water filtration. These products, such as geotextiles, geogrids, and geocells, help prevent soil erosion and stabilize slopes, reducing the amount of sediment that enters stormwater runoff. They also act as a barrier, filtering stormwater and removing pollutants before they reach water bodies. Additionally, geosynthetics can be used to construct permeable pavements and green roofs, which promote infiltration and reduce stormwater runoff volume. Overall, geosynthetic products contribute significantly to the overall effectiveness and sustainability of stormwater management practices.
Q:What are the advantages of using gabion walls?
There are several advantages of using gabion walls. Firstly, they provide excellent erosion control and soil stabilization, making them ideal for protecting slopes and riverbanks from erosion. Secondly, gabion walls are highly versatile and can be used in various applications such as retaining walls, noise barriers, and even artistic installations. Additionally, they are cost-effective compared to traditional construction methods, as they require minimal maintenance and are made from locally available materials. Moreover, gabion walls allow for natural drainage and prevent the accumulation of water, reducing the risk of flooding. Lastly, they are environmentally friendly, as they are made from wire mesh and natural stone, allowing for effective permeability and promoting biodiversity.
Q:How do earthwork products contribute to slope stabilization?
Earthwork products, such as geotextiles and geogrids, play a crucial role in slope stabilization. These products provide reinforcement and stability to slopes by effectively distributing the load and reducing soil erosion. Geotextiles act as a filter, allowing water to pass through but preventing the loss of soil particles. This helps in retaining the soil and preventing slope failure. Geogrids, on the other hand, provide tensile strength to the soil, enhancing its stability and resistance to lateral movement. Overall, earthwork products help in maintaining slope integrity, preventing erosion, and ensuring long-term stability.
Q:Construction and sales business tax how to calculate?
The construction industry applies a 3% business tax rate. The turnover of the construction business tax is the amount of revenue from contracting construction, repair, installation, decoration and other engineering operations. Construction and installation enterprises to the construction unit to collect the project price (ie project cost) and the project price charged outside the various fees.
Q:Are earthwork products suitable for use in riverbank stabilization projects?
Yes, earthwork products are suitable for use in riverbank stabilization projects. These products, such as geotextiles and geogrids, provide reinforcement and erosion control to prevent the riverbank from collapsing and help maintain its stability. Additionally, earthwork products are designed to withstand water flow and provide long-lasting support, making them a viable solution for riverbank stabilization projects.
Q:What is the meaning of the wetting angle in civil engineering materials?
Wetting is the process of water adsorption on the surface of the material. It is an important behavior at the interface of the solid-liquid interface. The wetting angle is closely related to the nucleation of the crystal in the material.
Q:How do earthwork products contribute to slope stabilization in mining areas?
Earthwork products such as geosynthetics, soil amendments, and erosion control materials play a crucial role in slope stabilization in mining areas. These products can be used to reinforce unstable slopes, control erosion, and improve the overall stability of the terrain. Geosynthetics, for example, act as a barrier to prevent soil movement and provide additional strength to the slope. Soil amendments, on the other hand, enhance the soil's properties, making it more resistant to erosion and improving its stability. Erosion control materials like blankets and mats help to protect the surface of the slope, reducing the impact of rainfall and preventing the formation of gullies. By utilizing these earthwork products, mining areas can minimize the risks associated with slope instability and ensure the safety and productivity of the operations.
Q:How do earthwork products contribute to erosion control?
Earthwork products, such as geotextiles and erosion control blankets, play a crucial role in erosion control. These products are designed to stabilize soil and prevent erosion by reducing the impact of water and wind on the exposed surfaces. They create a protective barrier that helps retain soil particles, control runoff, and promote vegetation growth. Additionally, earthwork products enhance the structural integrity of slopes, embankments, and other areas prone to erosion, ensuring long-term stability and reducing the risk of environmental degradation.
