Background
The glass fiber reinforced plastic has high tensile strength and low shearing strength. The biggest difference between the glass fiber reinforced plastic and the steel bar is that the glass fiber reinforced plastic has small elastic modulus and is a typical brittle material, and the stress-strain curve shows obvious linear relation before fracture, thereby greatly influencing the stability of the glass fiber reinforced plastic cage during lifting and the bending resistance and shearing resistance of the glass fiber reinforced plastic continuous wall in the excavation stage of the foundation pit. The glass fiber reinforced bar has high bearing capacity and strong tensile capacity, the strength of the bar body is twice of that of the threaded steel bar with the same diameter, but the mass of the bar body is only 1/4 of that of the steel bar; the elastic die is stable and is 1/3-2/5 of the steel bar. The electric heating insulation has the characteristics that the thermal expansion coefficient is closer to cement than that of reinforcing steel bars, and the like, and is mostly applied to shield underground continuous walls, upright posts and uplift piles, including the range of the in-out hole ground walls of end wells of subway stations, and most of the underground continuous walls, the upright posts and the uplift piles are made of glass fiber bars.

Such as in reinforced concrete, for supporting the skeleton of a structure. Comprises plain round steel bars, ribbed steel bars and twisted steel bars.
In order to reduce the influence of guard pile reinforcing bars on a later stage tunnel tunneling line on a shield tunneling machine, all longitudinal bars, stirrups and reinforcing bars of a guard pile reinforcing cage below the elevation of the basement slab bottom need to be made of glass fiber bars so as to ensure that the later stage shield can smoothly pass through, and common reinforcing bars are still adopted at the upper part of the reinforcing cage. The glass fiber ribs cannot be welded, so that the glass fiber ribs and the reinforcing steel bars can only be overlapped to form a whole. The prior art does not have a method for stably connecting glass fiber reinforcements and glass fiber reinforcements in a reinforcement cage. Thereby lead to in the steel reinforcement cage between the glass fiber muscle, the connection between glass fiber muscle and the reinforcing bar is firm inadequately, influences the whole steadiness of steel reinforcement cage.
