Geomembrane is actually a soft and thin impermeable engineering material, which mainly has the following characteristics and advantages: (1) Good permeability, continuous and dense geomembrane, as long as the design and construction quality are en...

Before laying the composite geomembrane, in order to ensure the smooth progress of the geomembrane laying, minimize wrinkles, cutting, and material waste, avoid cross joints and ensure that the distance between the transverse welds of two adjacent...

The waterproof board is the key to the waterproof composite lining of the tunnel, and its quality directly affects the waterproof function. With the increasing awareness of environmental protection, the importance of tunnel waterproofing is self-e...

(1) When pasting geotextiles, strictly control the amount of hot asphalt within the range of 0.8 ~ 1.2 kg/m2. If the amount of paving is too large, the bottom surface of the geotextile will be slippery and displaced after the asphalt mixture is sp...

Fiberglass grid design In order to prevent reflection cracks in motor vehicle lanes, and to strengthen the pavement strength in special places such as bus stops and wells, it is necessary to increase the glass fiber grid. Lay a glass fiber grid be...

Geosynthetics is called the fourth important building material besides wood, steel, and concrete. It has six functions of filtration, drainage, isolation, reinforcement, protection, and anti-seepage, enabling geosynthetics to solve many engineerin...

1. Prepare solutions with pH 2, 4, 6, 8, 10, and 12 to satisfy the impregnation of non-woven geotextiles and number them respectively; 2. Take the polyester filament geotextile of the same specification (200 g/m2, 20 cm × 8 cm), and immerse two pi...

Composite geomembrane is a composite product of geomembrane and geotextile (mostly non-woven needle-punched geotextile). Through the design and construction practice of anti-seepage engineering in recent years, composite geomembrane has broad pros...

During the construction of high-density polyethylene geomembrane, the flat base of the bottom of the reservoir and the slope must meet the design requirements and the following requirements. 1. Before laying, the laying surface should be protected...

Artificial lakes usually have poor self-purification capacity, fragile ecosystem structure, and are easily affected by many uncertain external factors. Therefore, how to maintain a large area of ​​water at a certain water level for a long time, en...
