The installation of the grid fiberglass structure of the puncture-proof colloid 103 in the low-speed tire is relatively simple. The middle of the anti-prick colloid 103 is not required to be embedded with grid glass fibers (grid glass fibers) or double-sided grid glass fiber adhesive tapes, and the bottom of the colloid 106 is not required to be provided with the double-sided grid glass fiber adhesive tapes. A double-sided grid glass fiber adhesive tape is adhered to the upper part of the anti-prick colloid 103, the width of the double-sided grid glass fiber adhesive tape is 0.1-10cm larger than that of the colloid 106, the adhesive tapes on two sides are normally selected to be 1-5cm larger than that of the colloid 106, the colloid 106 is wrapped through reverse wrapping, the colloid 106 with a certain width (2/3 on the surface of the colloid 106) reserved at the bottom of the anti-prick colloid 103 is not wrapped by the glass fiber adhesive tape, the purpose is that the bottom colloid 106 is more firmly bonded with the inner side of the tire 104, and the glass fiber colloids 106 which are reversely wrapped on two sides are also bonded with the inner side of the tire 104.
