by Richard Mrax Crusher Machine
What are the requirements for construction testing? The quality of geotextiles includes the quality of the raw materials in the field, the progress of the earthwork operation, and the quality testing of the earthwork. 1. The quality of the raw materials for the synthetic filament nonwoven geotextile factory price must be presented with the decent documents required by the manufacturer, the functional and characteristic guidelines and the application notes. Either it can be used for construction 2. The process of earthmoving operation. Grasp the geotechnical fabric before construction. Imagine the construction method and skill method, and indicate the construction method and skill method. After supervision approves the application, the earthmoving personnel should wear flat shoes or soft rubber shoes to stop the construction. It is forbidden to wear rain shoes to prevent The high quality filament nonwoven geotextile should be trampled, so that it can be spread along with the pressure. The construction of the geotextile should be in harmony with the construction of the protective layer. The quality of the welded seam is the key to the splicing. The joint detection is especially strengthened in the moving soil. The detection method includes a grass test method and second spot leak detection. After the filament nonwoven geotextile for sale is riveted, observe whether there is any missing joint, whether the seam is scalded, whether there is wrinkle, and whether it can be stitched evenly. On-site leak detection adopts the charging method to stop the detection of the complete pair of welds. The welds are double strips, with a cavity of about 10mm between the two. Seal the two ends of the section to be tested, pull out the gas needle, and charge to 0.05mpa-0.20 mpa, observe for 0.5min, observe the vacuum gauge, if the air pressure does not drop, it indicates no leakage, the weld is decent, whether to find the reason for correction in time.
