High strength epoxy-barbed wire structure block strengthening technology
The invention discloses a high strength epoxy-barbed wire structure block strengthening technology to perform site treatment of consolidation by grouting for a structure construction block. The strengthening technology comprises the steps of arranging form boards on the surface of a structure to be treated and laying isolating layers on the inner sides of the form boards; placing embossing woven barbed wire built-in fittings as reinforcements in the form boards; pouring epoxy resin grouting materials with high-strength, high temperature resistance and high fluidity into the form boards; a section reinforcement ratio is 1%; removing the form boards after the epoxy resin is cured and completing the strengthening operation. According to the high strength epoxy-barbed wire structure block strengthening technology, characteristics of the high strength and high temperature resistance of the epoxy resin grouting materials are maintained, and furthermore toughness of the epoxy resin grouting materials is obviously improved, the reinforcement treatment is conducted on reinforcing bar concrete or prestressed concrete with a increasingly weak structure bearing capacity, the normal service bearing capacity of the reinforcing bar concrete or the prestressed concrete is restored and improved, and therefore the tensile strength limiting strain of the reinforcing bar concrete or the prestressed concrete is enhanced.
