Welding Construction Process Of Geomembrane
- Composite Geomembrane Laying
In the course of laying textured high quality HDPE geomembrane, the development staff must adhere to the principle of top-down, laying things consistent with the vertical deviation of the axis, and there’s no got to leave longitudinal cracks within the center. At this stage of construction, construction technicians must concentrate to the punishment of foundation treatment and make sure the smoothness and cleanliness of the pavement. it’s also necessary to inquire and visit the solid degree of the soil, so on avoid the uneven environment of the paving surface and repair the cracks in it. During the course of paving, construction staff shouldn’t wear shoes that are hard or with nails at rock bottom . the selection of leverage objects must even be careful, and therefore the material should be effectively protected. so as to avoid damage to the film caused by wind, it’s necessary to use sandbags or other soft objects to affect heavy pressure within the course of laying all materials, so on lay an honest foundation for laying things.
- Suture Welding of Composite Geomembrane
Firstly, it’s necessary to punish rock bottom Geotextiles by sewing, then bond the center geomembrane, and eventually punish the upper Geotextiles by sewing. Before the welding construction is administered , it’s necessary for construction technicians to check the welding technology, so on determine the temperature and speed control of the welding machine on the development day and adjust it properly consistent with the particular construction situation. When the temperature is within the range of 5,135 degrees Celsius, it’s appropriate to hold out welding work. If the temperature isn’t within this range on the day of construction, it’s necessary for construction technicians to end their work and find effective steps for improvement. Before welding construction, it’s necessary to wash up the impurities on the welded surface, make sure the cleanliness of the welded surface, and punish the existence of water and gas within the welded surface by blowing dryer, in order that the welded surface are often maintained dry. During the connection process of multiple aquaculture wholesale HDPE Liner made in China, the joint cracks must be staggered for quite 100 centimeters, and therefore the welded joints must be T-shaped, therefore the welded joints can’t be set as cross-shaped. After the completion of welding construction, it’s necessary to hold out quality inspection and connection to avoid defects like welding leakage and folding. During the method of welding construction and within two hours after welding, the welding surface can’t be subjected to any tension stress to avoid damage to the welding position. If serious welding problems like void and bulge are found in welding quality inspection, it’s necessary for welding staff to chop off the welding position and punish the joint position after new welding. within the case of welding leak, it’s necessary for welding staff to use special welding torches for repair and treatment punishment. Welding technicians must perform the welding work strictly consistent with the planning request welding specifications when welding geomembrane. they ought to make sure the relevant standards of welding quality satisfaction and fully show the impervious and windward features of composite geomembrane.
- Geotextile Stitching
The upper geotextiles and therefore the middle high quality aquaculture geomembrane are overlapped on each side , and therefore the bottom geotextiles are laid, lapped, aligned and sewed up. The hand-held home appliance is tailored for geotextile sewing. the stitching distance should be controlled at 6 mm. The connection surface is moderately tight, natural and smooth. Geomembrane and geotextile are jointly stressed. the stitching measures of the upper geotextile are an equivalent as those of the lower geotextile.
