Problems solved by technology

[0002] The traditional method of anchoring fences is mostly cement reinforcement. Two or more people are required to operate during the anchoring process. In order to achieve a better anchoring effect, more materials are usually used, resulting in a waste of manpower and material resources.
[0003] At present, resin materials and polyurethane materials are also used for anchoring. The resin anchoring agent is a viscous anchoring adhesive material prepared in a certain proportion from unsaturated polyester resin, curing agent, accelerator and other auxiliary materials. The divided packaging of ester film is in the shape of medicine roll, which has excellent properties such as fast curing at room temperature, high bonding strength, reliable anchoring force and good durability, but its fluidity and permeability are poor
Polyurethane anchoring agent is composed of two components of materials that are stirred, foamed, infiltrated, and then anchored after curing. However, the existing polyurethane anchoring agent has relatively complex components, high viscosity, and poor permeability.
