A high-strength epoxy-barbed wire structure block reinforcement process

Abstract

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.

Description

technical field [0001] The invention relates to a novel reinforcement grouting material, which belongs to the technical field of structural engineering reinforcement maintenance. Background technique [0002] According to incomplete statistics, due to factors such as vehicle overruns, environmental erosion, and material aging, more than one-third of my country's main highway bridges currently have hidden dangers such as structural defects, damage to varying degrees, and partial functional failures, which seriously threaten the safety of bridges. , has become a bottleneck restricting the development of my country's road transportation. [0003] In foreign countries, bridge reinforcement materials have attracted widespread attention, and international specialized institutions have been established for research. High-performance concrete (HPC) is developed from high-strength concrete. It is a new type of high-tech concrete. Its configuration is characterized by the use of low w...

Problems solved by technology

[0005] 2. During the reinforcement construction process of existing materials, it is difficult to make and takes a long time to maintain

The general concrete curing period is about 28 days; fiber concrete is easily distributed unevenly due to the influence of the mixing process during the mixing process, and the controllability and testability are poor.

[0006] 3. The low bonding performance between the reinforcement material and the base metal, and the high requirements for reinforcement technology affect the reinforcement effect
