Application of geocells in ecological construction of highway projects

In recent years, there has been a growing focus on integrating ecological protection with engineering projects, especially in highway design. The goal is to ensure that highways not only serve as transportation corridors but also harmonize with the surrounding environment, enhancing slope stability and reducing environmental impacts like erosion and noise. Geocell Characteristics: Constructed from durable HDPE, forming a 3D cellular grid. Lightweight, corrosion-resistant, and easy to transport and install. Provides strong lateral confinement and anti-slip properties, enhancing slope integrity. Ecological Protection Mechanism: Geocells stabilize slopes by confining soil or growth media, promoting vegetation growth. Facilitate rainwater infiltration, reduce erosion, and protect plant roots, contributing to long-term slope stability and environmental benefits. Key Considerations: Follow product guidelines for selection and storage of geocells. Optimal slope gradient should not exceed 1:1, with excavation heights limited to 8-10 meters. Ensure proper thickness and compaction of fill materials within cells. Avoid construction during rainy seasons to prevent washout. Select suitable local vegetation and manage irrigation and drainage effectively. Overall, geocell technology offers an eco-friendly solution for slope protection, combining mechanical reinforcement with ecological restoration to support sustainable infrastructure development.

Geocell laying construction control

Geocell is a geosynthetic material made from high-density polyethylene (HDPE) or polypropylene (PP) strips, welded or riveted to form a grid-like cellular structure. It provides reinforcement, isolation, and load distribution in geotechnical applications by confining soil particles within its cells, thereby enhancing the bearing capacity and stability of foundations. Quality control measures include: Ensuring raw materials meet design standards, are undamaged, and free from contamination. Proper preparation of the underlying layer, including leveling, compaction, and removal of sharp objects. Correct orientation of the geocell with its high-strength direction aligned to the main stress direction. Secure installation, tensioning, and anchoring of the geocell, followed by timely backfilling. Prohibiting direct contact or movement of heavy machinery on the geocell before covering. On-site supervision and documentation during installation as a hidden works process. The geocell paving process involves: Subgrade reinforcement → cleaning → leveling and compacting → U-nail fixation → geocell installation and tensioning → fixing → inspection → gravel backfill → compaction → final inspection. Using specialized tools for laying geocells ensures even tensioning, prevents deformation, maintains close contact with the subgrade, and improves efficiency and quality. In contrast, manual laying is slower, labor-intensive, and may result in uneven stress distribution and lower construction quality.

Research on rough geomembranes

Rough geomembrane (glossy geomembrane): It is a new type of waterproof building material used for seepage and moisture-proofing, which is made of high-density polyethylene resin by adding a certain proportion of carbon black masterbatch, anti-aging agent, antioxidant, ultraviolet ray absorber, stabiliser, etc. It is a new type of seepage and moisture-proof building material. Rough-faced HDPE geomembrane is a new type of seepage control and anti-corrosion material, which is widely used in various projects with seepage control and anti-corrosion requirements. It is made of high-quality HDPE virgin resin, the main component of which is 97.5% HDPE, about 2.5% carbon black, trace antioxidant and heat stabiliser, anti-ageing material, ultraviolet absorber, no other additives, fillers and expanders, and it is made by three-layer co-extrusion technology. The resins used are virgin high or medium density polyethylene resins specially formulated for geomembrane applications.

Functions of non-woven geotextiles

Non-woven geotextiles play five key roles in civil and environmental engineering: Filtration – Retain soil while allowing water to pass, used in landfills, dams, and tailings ponds. Polypropylene types are chosen for acid/alkali resistance. Drainage – Collect and channel water away in roads, dams, and slopes. Thick varieties provide better drainage with less demand on mechanical strength. Geomembrane Protection – Protect impermeable HDPE membranes from UV damage and physical wear in landfills. Polyester types offer better UV resistance. Isolation – Prevent mixing of different materials (e.g., soil and gravel), used in railways and foundations. Provides insulation and vibration control. Reinforcement – Improve soil stability in light reinforcement tasks like road bases. High-strength polypropylene types are preferred under harsh conditions. Material choice depends on function, environment, and chemical exposure.
