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: Can earthwork products be used in road embankment construction?
Yes, earthwork products can be used in road embankment construction. Earthwork products such as soil, gravel, and other materials are commonly used to build road embankments. These materials are compacted and shaped to create a stable and durable base for the road.
Q: How are geotextile tubes used in sediment dewatering?
Geotextile tubes are used in sediment dewatering by containing the sediment within the tube and allowing the water to drain out through the permeable fabric. The tubes are filled with sediment slurry, and as the water seeps through the geotextile fabric, it is separated from the solid particles. This process effectively removes excess water from the sediment, allowing for easier disposal or further treatment.
Q: Will the mechanical material mechanics and civil material mechanics different?
The difference is definitely big, the mold does not change. But the mechanical and electrical materials and civil nature is not the same
Q: What are the different surface textures available for earthwork products?
There are various surface textures available for earthwork products, including smooth, rough, grooved, and textured.
Q: How are geotextile mats used in sediment control during river dredging?
Geotextile mats are used in sediment control during river dredging by being placed on the riverbed to prevent the stirred-up sediments from spreading downstream. These mats act as a barrier, trapping the sediments while allowing water to pass through. This helps to minimize the environmental impact of dredging activities by reducing sedimentation in downstream areas and protecting water quality.
Q: What are the key considerations when using geotextile bags for shoreline restoration?
When using geotextile bags for shoreline restoration, some key considerations include the choice of geotextile material, the size and weight of the bags, proper installation techniques, the stability and durability of the bags, and the potential impact on the surrounding ecosystem. Additionally, factors such as wave action, water currents, and soil conditions should be taken into account to ensure effective and long-lasting shoreline restoration.
Q: How do geogrids help in soil stabilization?
Geogrids help in soil stabilization by providing reinforcement and improving the overall strength and stability of the soil. They are typically made of high-strength materials and are placed within the soil to create a network of interlocking grids. This helps to distribute and transfer the loads and stresses applied to the soil, preventing soil movement, erosion, and settlement. Geogrids also enhance the load-bearing capacity of the soil, making it more suitable for construction projects and preventing potential failures.
Q: Are earthwork products suitable for use in wetland restoration?
Yes, earthwork products are suitable for use in wetland restoration. They can be used for various purposes such as creating berms, shaping the landscape, and constructing water control structures. Earthwork products, such as soil, gravel, and clay, can help to establish the desired topography and hydrology of wetlands, facilitating the restoration process and supporting the growth of wetland vegetation. Additionally, these products can help in preventing erosion and improving water quality, making them valuable tools for wetland restoration projects.
Q: What are the specific applications of geotextile tubes in coastal protection projects?
Geotextile tubes are commonly used in coastal protection projects for various applications. Some specific uses of geotextile tubes include shoreline stabilization, beach nourishment, and coastal erosion control. These tubes are often filled with sand or other suitable materials and placed strategically along the coastline to create barriers that absorb wave energy, prevent erosion, and protect the shoreline from storm surges. Additionally, geotextile tubes can be used to restore and enhance beaches, dunes, and marshes, providing habitat for various plant and animal species while also safeguarding coastal communities from the impacts of climate change and sea-level rise.
Q: What are the benefits of using concrete pipes in earthwork?
Concrete pipes offer several benefits in earthwork projects. Firstly, they have high strength and durability, making them suitable for withstanding heavy loads and extreme weather conditions. They are also resistant to corrosion, which ensures a longer lifespan compared to other materials. Additionally, concrete pipes have a smooth inner surface, promoting efficient water flow and minimizing the risk of blockages. They are also relatively easy to install, maintain, and repair, saving time and costs during construction and maintenance activities. Overall, concrete pipes provide a reliable and long-lasting solution for various earthwork applications.
