The selection of composite geomembrane specifications are related to the flatness of the cushion, the allowable tensile stress of the material, the elastic modulus of the material, the maximum water head within the laying range, and the maximum pa...

(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...

Non-woven fabric is made of fiber mesh and consolidation. The fiber has a three-dimensional structure, good ductility, and mechanical properties. Different materials and processes can be used to design fabrics with a wide range of structural featu...

Use special underwater geotextiles built by deck barges to lay the vessel. Before laying the geotextile, all preparations should be made. Create a GPS differential reference station, input the GPS mobile station of the geotextile laying ship accor...

Geomaterials have multiple functions, including reinforcement, isolation, protection, anti-seepage, filtration, and drainage. 1. Enhanced functions. The geosynthetic material placed in the soil can disperse the soil stress, transmit tensile stress...

Engineering composite geomembranes generally use two types: two cloths and one membrane and one cloth and one membrane. In order to facilitate detection, enhance anti-aging performance, and facilitate construction, the width of the composite geome...

Artificial lake seepage prevention methods generally include reinforced concrete waterproofing, clay waterproofing, and composite geomembrane waterproofing methods. The following three methods are introduced respectively. 1. Reinforced concrete is...

During construction, we must not only ensure the efficiency of the construction but also ensure the quality of the construction. Not only should the construction be completed, but we must also always pay attention to some problems during the const...

Na-based bentonite waterproof blanket is a new type of environmentally friendly ecological composite impermeable material. Because of its good impermeability, flexibility, waterproofness, and ease of construction, it plays a good role in water con...

On the upper part of the anti-seepage structure, there are structures such as a leachate drainage pipe network, an exhaust pipe network, and a drainage pipe network. The anti-seepage structure belongs to a new type of composite anti-seepage liner ...
