(5) manufacturing a binding opening drawstring at the edge of the outermost fiber layer in the shape of an elliptic cylinder, wherein the binding opening drawstring is made of polyester fibers;
(6) leaving the position of an upper suture line at the position of 5-8cm above the outermost fiber layer in the elliptic cylinder, and sewing the outer layer, the middle layer and the protective layer together by the suture line after the asphalt is poured;
(7) a circle of steel pipe is arranged at the position adjacent to the suture line of the step (5), the diameter of the steel pipe is 3mm, and the steel pipe is used for opening the opening of the package and easily pouring asphalt into the package;
(8) two steel pipe caps are respectively arranged on two sides of the packaging bag, which are at the same height with the steel pipes, and the steel pipe caps are made of thin steel sheets with the thickness of 1 mm.
The utility model discloses beneficial effect as follows:
(1) after the coating covered by the protective layer is cured, the coating has good film forming property, good adhesion with a fiber layer and difficult peeling of the fiber layer, but the inner surface of the protective layer is smooth and easy to peel off from asphalt, the appearance is not easy to damage and can be repeatedly used, when the coating is used for the second time, an upper suture line is dismantled, and the outermost layer and the middle layer fiber layer are combined for reuse again.
(2) The lower end of the outermost fiber layer is provided with the drawstring at the binding port, so that the discharging is more convenient during use.
