The laying of geotextile is not very troublesome. Generally, there will be no problems when you need to operate according to the requirements. If you don’t know how to lay geotextiles, you can take a look at the contents introduced in this article, which may be helpful for you to lay geotextiles.

1. Geotextile laying. The construction personnel must adhere to the principle of top-down according to the geotextile during the laying process. According to the vertical deviation of the axis, there is no need to leave the connection of the central longitudinal crack. In this stage of construction, the construction personnel must pay attention to the punishment of foundation treatment to ensure that the paved ground is flat and clean. In order to avoid the uneven environment on the pavement surface and repair the cracks on the surface, it is also necessary to query and visit the soil solidity. During the laying process, construction personnel should not wear too hard shoes or have nails at the bottom. It is also necessary to be careful when selecting the object of fuzzing to effectively protect the material. In order to avoid the damage of the membrane caused by the wind, all materials need to be heavily punished with sandbags or other soft objects during the laying process, laying a good foundation for the laying of materials.
2. Geotextile sewing and welding. In the process of connecting things, the construction personnel must adhere to the response principle to ensure the standardization of the connection. First, the bottom geotextile shall be sewn for punishment, then the middle geotextile shall be bonded, and then the top geotextile shall be sewn for punishment. Before welding construction, construction technicians must inspect the welding process to determine the temperature and speed control of the welding machine on the construction day, and make appropriate adjustments according to the actual construction conditions. When the temperature is between 5 and 35 ℃, welding is more appropriate. If the temperature of the construction day is not within this range, the construction technicians must complete the work and seek effective improvement. Before welding, the impurities on the welding surface shall be cleaned to ensure the cleanness of the welding surface. The moisture on the welding surface can be dried by electric hair dryer. The welding surface can be kept dry. During the connection of multiple geotextiles, the joint cracks must be staggered by more than 100cm, and the welded joints must be t-shaped, and the welded joints cannot be set as cross-shaped. After the completion of welding construction, the quality control of connection shall be carried out to avoid welding leakage, folding and other adverse problems. During welding and within two hours after welding, the welding surface shall not be subject to tensile stress to avoid damage to the welding position. If serious welding problems are found in the welding quality inspection, such as empty welding, expansion welding, welding personnel need to cut the welding position, welding interface position and other new punishment welding. If there is leakage in the welding environment, the welding personnel must use a special welding gun for welding repair and disposal. When welding the geotextile, the welding technician must weld the geotextile in strict accordance with the design requirements to ensure that the welding quality meets the relevant standards, and the geotextile must fully show the impermeable wind.
3. Geotextile stitching. Fold the upper geotextile and the middle geotextile to both sides, and then flatten, overlap, align and sew the lower geotextile. Hand-held sewing machine is used for geotextile sewing, and the clockwise distance is controlled within 6 mm. The joint surface is moderately loose and smooth, and the geotextile and geotextile are in joint stress state. The upper geotextile stitching measures are the same as the lower geotextile stitching measures. As long as the above methods are followed, generally speaking, there should be no problems, but you should also pay attention to the maintenance of geotextile capacity in the future.
