Description

Technical Field

[0001] The utility model relates to the technical field of ground crack repairing, in particular to a ground crack repairing device. Background Art

[0002] Epoxy coil is a new type of floor material in the flooring industry. It is a polymer composite material made of elastomer toughened epoxy resin and polyurethane compound resin system as the matrix, glass fiber toughening and reinforcement, and prepared through a special curing process. Epoxy coil laying on the ground is conducive to improving the beauty and cleanliness of the ground.

[0003] However, before laying the existing epoxy membrane, the cracks on the ground need to be repaired. If the epoxy membrane is laid without repairing the cracks, the long-term expansion and contraction of the cracks due to thermal expansion and contraction will cause wrinkles on the epoxy membrane at the positions corresponding to the cracks. Therefore, the cracks on the ground need to be repaired.

[0004] The existing method of repairing ground cracks is generally to manually move equipment to cut at the cracks to form a groove perpendicular to the cracks, and then put a steel bar in the groove to strengthen the lateral tension of the cracks to prevent the cracks from cracking again. Finally, workers manually fill the cracks with caulking agent. When filling the caulking agent, workers need to bend over to work. Since the crack repair requires workers to use equipment to cut on the ground, and finally workers need to bend over to manually fill the cracks with caulking agent, the labor intensity of workers is high, and they need to frequently move equipment, resulting in low repair efficiency.
