1. Project requirements and scale
Large-scale project requirements: For large-scale geotechnical dams, rockfill dams, masonry dams and other projects, due to their large scale and the wide area to be covered, choosing a wider Composite geomembrane can reduce the number of splicing times. The reduction in the number of splicing times improves construction efficiency and reduces the risk of anti-seepage failure caused by improper splicing. Large-scale projects usually give priority to the use of Composite geomembrane with a width of 4-6 meters to ensure the continuity and integrity of the construction.
Small-scale project requirements: For some small-scale projects or local anti-seepage treatments, due to limited construction space and the possibility of complex terrain, it is more appropriate to choose a narrower Composite geomembrane. Narrower Composite geomembrane are easier to lay and adjust in a small space, can better adapt to complex terrain conditions, and ensure anti-seepage effects.
2. Construction conditions and site environment
Terrain and transportation conditions: The terrain and transportation conditions of the construction site have a direct impact on the selection of the width of the Composite geomembrane. If the terrain of the construction site is complex and the transportation conditions are limited, it will be more convenient to choose a narrower Composite geomembrane, which will facilitate transportation and laying and reduce the difficulty of construction. On the contrary, if the construction site conditions are good, the terrain is flat, and transportation is convenient, choosing a wider Composite geomembrane can improve construction efficiency and reduce material waste.
Construction equipment: The size and type of construction equipment will also affect the choice of Composite geomembrane width. If the construction equipment is small and the operating space is limited, choosing a narrower Composite geomembrane will be more flexible and convenient for operation. If the construction equipment is large and the operating space is sufficient, choosing a wider Composite geomembrane can increase the construction speed and reduce the construction time.
3. Material performance and quality
Material uniformity: The uniformity and performance of Composite geomembrane of different widths may vary during the production process. Wider Composite geomembrane require higher technical and equipment requirements during the production process to ensure the uniformity and performance of the materials. When choosing the width of the Composite geomembrane, it is necessary to comprehensively consider the performance and quality of the materials and choose a width suitable for the project needs to ensure the anti-seepage effect and project safety.
Technical and equipment requirements: Wider Composite geomembrane require higher technical and equipment requirements during the production process to ensure the uniformity and performance of the materials. When choosing the width of the Composite geomembrane, it is necessary to understand the technical level and equipment conditions of the manufacturer, and choose a qualified and experienced manufacturer to ensure the quality and performance of the material.
4. Economy and cost-effectiveness
Material cost: Although the wider Composite geomembrane may have higher material costs, it can reduce construction costs and improve construction efficiency due to the reduction in the number of splicing times and construction time. When choosing the width of the Composite geomembrane, it is necessary to comprehensively consider the material cost and construction cost and choose an economically reasonable width.
Construction cost: On the premise of meeting the project requirements and construction conditions, choosing an economically reasonable width of the Composite geomembrane can effectively reduce the project cost and improve economic benefits. A wider Composite geomembrane can reduce the number of splicing times, reduce the difficulty of construction, increase the construction speed, reduce the construction cost, and improve the economic benefits.
