                                       sodium Bentonite Geosynthetic Clay Liner(GCL)

 

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.

 

3,Application

(1)Municipal engineering, underground engineering subways, buildings and roofs reservoir seepage.

(2)Environmental sanitation, solid waste landfills, sewage treatment plants, industrial waste.

(3)water, rivers, lakes and reservoirs dam seepage, plugging, reinforcement.

(4)Garden artificial lake golf course pond seepage and so on.

(5)Petrochemical, mining and other areas of engineering seepage, leakage, etc.

Q: Can earthwork products be used for bridge construction?
Yes, earthwork products can be used for bridge construction. Earthworks involve the manipulation of soil and other natural materials, and these materials can be utilized for various aspects of bridge construction, such as embankments, approaches, and abutments.
Q: Are earthwork products suitable for use in pipeline construction?
Yes, earthwork products are suitable for use in pipeline construction. Earthwork products such as soil, gravel, and crushed stone are commonly used in pipeline construction for backfilling and providing stable support to the pipeline. These materials help to prevent ground movement, erosion, and provide a solid foundation for the pipeline, ensuring its stability and longevity. Additionally, earthwork products can be engineered and compacted to meet specific requirements and ensure the pipeline's integrity.
Q: Can geotextile tubes be used for dewatering?
Yes, geotextile tubes can be used for dewatering. They are commonly used in various industries and construction projects to remove water from sediment or sludge by allowing the water to drain through the porous fabric while retaining the solid particles inside the tube.
Q: Can erosion control blankets be used on slopes?
Yes, erosion control blankets can be used on slopes. These blankets are designed to stabilize soil and prevent erosion by reducing rainfall impact and promoting vegetation growth. They can effectively control erosion on slopes by providing immediate protection to the soil surface and allowing vegetation to establish and grow, helping to stabilize the slope and prevent further erosion.
Q: What are the benefits of using geocells in pavement applications?
Geocells have several benefits when used in pavement applications. Firstly, they provide a stable base for the pavement, reducing the need for excessive excavation and aggregate materials. Secondly, geocells enhance the load-bearing capacity of the pavement, making it suitable for heavy traffic and reducing the likelihood of rutting or potholes. Additionally, geocells improve the overall performance and longevity of the pavement by distributing the load evenly, preventing lateral movement, and increasing resistance to erosion and environmental factors. Overall, using geocells in pavement applications can result in cost savings, improved durability, and reduced maintenance needs.
Q: Are earthwork products suitable for shoreline protection?
Yes, earthwork products can be suitable for shoreline protection. They can be used to create berms, dunes, or other structures to help prevent erosion and protect the shoreline from wave action. These products offer stability and durability, making them an effective solution for shoreline protection in certain conditions.
Q: Civil engineering materials, what kind of
Classification by material source According to the material source, can be divided into natural materials and man-made materials. The man-made materials can be metallurgical, kiln (cement, glass, ceramics, etc.), petrochemical and other materials manufacturing sector to classify.
Q: How do earthwork products contribute to stormwater infiltration?
Earthwork products, such as permeable pavements, rain gardens, and bioswales, play a crucial role in promoting stormwater infiltration. These products are designed in a way that allows rainwater to seep into the ground instead of running off into storm drains or water bodies. By capturing and filtering stormwater, earthwork products help reduce the volume and velocity of runoff, prevent erosion, and recharge groundwater aquifers. This contributes to improved water quality, reduced flooding, and sustainable management of stormwater in urban areas.
Q: What are the different applications of geonets?
Geonets have various applications in civil engineering and environmental projects. They are commonly used as drainage systems to prevent water buildup and control erosion in areas such as road construction, landfill liners, and retaining walls. Geonets also provide reinforcement and stabilization in soil and slope applications, helping to improve the overall strength and stability of the structures. Additionally, they can be utilized as filtration and separation layers in geotextile and geocomposite systems, aiding in the efficient drainage of liquids and preventing the mixing of different soil layers.
Q: What are the key factors to consider when choosing earthwork products?
When choosing earthwork products, some key factors to consider include the quality and durability of the products, their compatibility with the specific earthwork project requirements, their ease of installation and maintenance, as well as their cost-effectiveness and environmental impact.
