Case Study: Geosynthetics Used in Solid Waste Field Anti-seepage Project

Case study geosynthetics used in solid waste field anti seepage projects 6

The industrial solid waste disposal project in Yunxi District utilized geotechnical materials such as geomembranes, filament geotextiles, GCL bentonite waterproof blankets, and composite drainage nets, all provided and implemented by QIVOC. Despite challenges such as geological conditions, overlapping operations, and the pandemic, the project was completed. Project Overview The industrial solid waste disposal project in Yunxi District, China, aims to provide effective end-of-life disposal services for industrial enterprises in Yunxi District. The project is designed with a lifespan of 18 years. The site features uneven terrain, with higher elevations around the perimeter and lower elevations in the center. The surrounding area is primarily mountainous, and the center contains a quarry […]

3 鉄道建設におけるジオグリッドの活用事例

鉄道建設におけるジオグリッドの3つの技術事例

QIVOC is a geosynthetics company with many years of experience in production and research and development.

Application of Geogrid in Lalin Railway Project Introduction Lalin railroad is connected to the Lhasa and Linzhi railroads and is an important part of the Sichuan-Tibet railroad, the railroad is located in the southeast of the Tibetan plateau, across the fracture zone, high mountains and deep valleys, the climate is extremely harsh, there are many engineering geological problems, engineering construction […]

貯水池ダムにおけるジオテキスタイルの適用事例

貯水池ダムにおけるジオテキスタイルの使用例 3

A certain dam was completed in August 1955, with a designed storage capacity of 13.5 million m3, a dam height of 21.15 m, and a dam crest elevation of 1870 m. Because the dam foundation has a soft soil layer, the main dam is an arched homogeneous earth dam that curves upstream, 660 m long, and there are two auxiliary dams, 1128 m long, and the total length of the dam axis is 1788 m. Because the dam is located on the Tertiary sandy silt and fine sand layers, no foundation treatment was carried out, resulting in numerous water leaks, sand gushing and dam slope collapse after the reservoir was […]

Uniaxial Geogrid Used in Slope Protection and Greening Project Case

Uniaxial Geogrid Used in Slope Protection and Greening Project Case 11

The network structure has the functions of gathering soil, increasing the overall stability of the slope, and repairing the landslide slope. In mountainous areas with active earth crust, one-way geogrids are often used for mountain reinforcement and protection. After laying one-way geogrids on the slopes, the soil can be gathered, so that the slopes can resist rain erosion. In addition, the black one-way geogrid can resist ultraviolet radiation. Even if the grid is exposed to the outside of the soil, it will not be powdered or aged due to long-term ultraviolet radiation. Moreover, it is not afraid of rainwater erosion and corrosion, and cannot be replaced by heavy-duty reinforcement materials […]

HDPE Pond Liner Used In Marine Shrimp Pond Breeding Projects

HDPE Pond Liner Used In Marine Shrimp Pond Breeding Projects 4

Use high density polyethylene pond liner to build shrimp ponds for breeding fish and shrimps. Project Overview: A customer wanted to buy some polyethylene pond liners to build a pond. He has an animal and food processing factory with a large open space that he wants to use to build a shrimp pond and learned about the construction of shrimp ponds from QIVOC. Since the customer is in a tropical area with a lot of rain, we recommend to the customer a 0.5mm hdpe geomembrane pond liner and a 0.75mm geomembrane giant pond lining for shrimp farming. After communicating with the customer, they decided to use 0.75mm HDPE pond liner […]

Geotextile Project Case: Protection of Upstream and Downstream Banks of Water Gates Against Erosion

Protection of Upstream and Downstream Banks of Water Gates Against Erosion 1

In this project, geotextiles were employed to reinforce the banks both upstream and downstream of water gates, providing protection against erosion and ensuring the safe operation of the water gates. Project Overview: The Xi River embankment commonly features reinforced concrete box bottoms and prefabricated beam-type retaining walls for water gates. This type of watergate offers advantages such as ease of construction, low cost, and structural rationality. However, the riprap protection on the upstream and downstream banks of the gate chamber undergoes severe erosion during operation, necessitating significant manpower and material resources for annual maintenance. More critically, this situation continually jeopardizes the safe operation of the gate structure. Solution: To address […]

Geotextile Used In Rural Road Construction Projects

Geotextile used in rural road construction projects 2

Laying geotextile separation layers during the construction of rural roads can effectively enhance the lifespan and safety of the road, while also providing multifaceted protection to the road structure and the environment. In this project, the length of the road section with geotextile separation layers is 4670 m. The width of the installation is 9.88 m, and the area covered by the woven geotextile is 46140 ㎡. Construction Plan 1. Storage, Transportation, and Handling of Geotextile: Before installation, geotextile rolls should be stored in a flat area without water accumulation, and the stacking height should not exceed four rolls. Geotextile rolls must be covered with opaque material to prevent UV […]

HDPEジオメンブレンによる廃棄物処分場浄化の成功例

廃棄物残渣ダンプの汚染防止におけるHDPEジオメンブレンの成功例 1 1

The project involves the accumulation of solid waste, particularly smelting residues, generated annually by a large-scale mining enterprise. Due to the lack of any environmental protection measures at the deposition site, the waste residue heaps contain significant amounts of heavy metals such as lead, zinc, cadmium, and germanium. This has resulted in substantial pollution of groundwater and downstream soil and water environments. Project Overview In the 1960s, numerous mining enterprises operated in this mineral-rich region, engaging in mining and smelting activities. Over the years, the accumulation of solid waste, particularly smelting residues, occurred, and in conjunction with the disposal of some domestic and construction waste from residents, it gradually formed […]

埋立地浸出水処理におけるHDPEジオメンブレンの成功事例

埋立地浸出水処理におけるHDPEジオメンブレンの成功事例

This project involves the closure and capping of a landfill that has been operating for several years. Due to adopting a simplistic filling method during construction, significant volumes of leachate are generated during heavy rainfall and flood periods, leading to the discharge of leachate and causing severe pollution to the surrounding environment. Project Overview The landfill was constructed and operated early on, with low construction standards and open waste dumping. Following the decommissioning of this landfill, a soil cover has been applied, and a 12m high wall has been erected outside the waste disposal area. Additionally, a leachate pond has been constructed, measuring 30m in length, 20m in width, and […]
