The geotextiles(China Geotextile Manufacturer) selected for the anti-seepage of the reservoir are mostly geotextiles made of polyethylene. Because such geotextiles(Non Woven Geotextile On Sales) are soft in texture and strong in anti-aging, they are not simply cracked and have a long service life. As for the parameter value of the geotextile used, the thickness is generally between 0.8mm and 1.2mm, and the width is between 1.5 and 2 meters. It is planned at the time of laying that the laying needs to be carried out from the foot of the dam to the horizontal plane, and its purpose is to better prevent seepage.

Construction technology of geotextile

The construction technology and construction quality of geotextile have a great connection, and often determine the quality and service life of construction projects. So how should the geotextile be carried out during construction?

1. The cushion should be flat: such as debris and weeds should be removed in time, the unevenness of the slope should be cleared in time, and the silt at the bottom of the dam should be cleaned up in time to ensure that people will not get too serious when standing on the ground.

2. The stitching of geotextile(Non Woven Geotextile Wholesale) should be tight: there are generally three kinds of stitching of geotextile: lap, welding and bonding. No matter which stitching method is selected, there is no shortage of local ones to pay attention to to prevent leaks and affect the anti-seepage effect. .

3. The laying of geotextile: the direction of laying should be from bottom to top, the tightness should not be too close, to prevent the geotextile from cracking due to the effect of pressure during the compaction, and the speed of laying and the speed of the protective layer should be basically Keep it flat to prevent long-term exposure of the geotextile to sunlight and accelerate the aging of the geotextile.

4. Filling of the protective layer: the protective layer must not contain weeds and other substances, but it contains a certain amount of moisture, and the thickness of the laying should not be higher than 30 cm. How the protective layer is filled is the same as the geotextile's impermeability.
