[0025] Example 1
[0026] Such as figure 1 , 2 As shown, a new type of molding bag filter hole sewing processing and construction method is characterized in that it comprises the following steps:
[0027] ①According to the design requirements of the mold bag sewing process, after the blanking of the mold bag fabric and the initial sewing are completed, set out according to the hole position, and open a hole with a diameter of 150mm at the predetermined position of each bin as the water filter hole 5. Two tethers 1 are reserved around the hole, and a protective pipe cloth 3 matching the diameter of the water filter hole 5 is prefabricated, and the upper and lower water filter holes 5 of the mold bag are connected through the pipe protective cloth 3 by an overlock process to form a protective pipe cloth 3 的水滤孔5;
[0028] ②After laying the mould bag, manually insert the intercepted PVC water filter pipe 2 with a length of 1m and a diameter of 120mm into the protective tube cloth 3 of th...
