Or the mixing of epoxy resin and vinylite.
Further improvement of the present invention, further includes thermoplastic barrier layer, and thermoplastic barrier layer is arranged on the outer surface, thermoplasticity every
Layer by softening temperature is more than 110 DEG C, the material preferably between 140 to 170 DEG C is made.Thermoplastic barrier layer should advantageously have extremely
The elasticity of few not half, with can overcome for example as caused by temperature it is swollen between thermoplastic barrier layer and shield prefabricated pipe section
Stress caused by swollen difference, and thermoplastic barrier layer is not damaged or is torn and the sealing function of interlayer is not damaged.
Further improvement of the present invention, inner surface both ends are each provided with 4 sides for running through entire shield prefabricated pipe section main body
Shape fixation hole, convenient between shield prefabricated pipe section and be connected and fixed inside tunnel.
Further improvement of the present invention, boss surface are provided with 4 through the rectangular solid of entire shield prefabricated pipe section main body
Determine hole, the centre of 4 rectangular fixation holes is additionally provided with 1 circular fixation hole.
Beneficial effects of the present invention: for traditional concrete reinforcement is using reinforcing bar, present invention uses glass
Fiber bar not only has corrosion resistance as arrangement of reinforcement, is capable of the bulk life time of shield prefabricated pipe section, and tensile strength is high, about
It is twice of equivalent specifications regular reinforcement load, light-weight, the only a quarter of equivalent specifications reinforcing bar weight, thus significantly
Labor intensity of workers is reduced, transportation cost is reduced, also there is easy cutting, avoid damaging cutter in process of production
Head saves time and cost.
