At present, a round pipe culvert is mostly of a reinforced concrete structure, and the construction process flow generally comprises the following steps: measuring and lofting → foundation treatment → tube socket foundation pouring → tube coupling installation → residual tube socket foundation pouring → seam treatment → opening building → back filling of culvert and the like. However, many diseases can occur in the traditional round pipe culvert: the concrete pipe joint has radial, longitudinal, crack or fracture, edge damage and gap; sinking, staggering and splitting one end or the whole of the pipe joint; the asphalt floc in the pipe joint gap falls off; sinking the roadbed above the culvert, leaving the hole, and jumping the culvert top; water leaks from the pipe joint interface due to cracks, subsidence and the like, and drainage outside the hole is formed; the end wall and the wing wall incline outwards and are broken; the paved layer at the opening is cracked and flows downwards; if a common reinforced concrete round pipe culvert is adopted, after the steel bar is contacted with water for a long time, the steel bar is easy to corrode, the concrete is peeled off after the rust expansion, and the use of the culvert is influenced.
The material research shows that the glass fiber rib can achieve higher tensile strength, is light in weight and corrosion resistant, is a composite material compounded by taking high-strength glass fiber as a reinforcing material, taking synthetic resin as a base material and adding a proper amount of auxiliary agent, is 100% of inorganic fiber, has the mass of 1/4 of that of a reinforcing steel bar with the same volume and the density of 1.9-2.2 (g/cm < 3 >), and can achieve a better bonding effect with a concrete structure.
Therefore, the research of the round pipe culvert with strong corrosion resistance and large bearing capacity has important significance.
