Description

Technical Field

[0001] The utility model belongs to the technical field of reinforced concrete pipes, and more specifically, particularly relates to an anti-seepage reinforced concrete pipe. Background Art

[0002] Concrete pipes are pipes made of concrete or reinforced concrete, used to transport fluids such as water, oil, and gas. They can be divided into four types: plain concrete pipes, ordinary reinforced concrete pipes, self-stressed reinforced concrete pipes, and prestressed concrete pipes. Among them, reinforced concrete pipes are very common.

[0003] Based on the above, the inventors have found the following problems: most traditional concrete pipes are cast from cement and steel frames. Since cement is water-absorbent and concrete pipes need to be pre-buried in the soil, the concrete pipes are susceptible to corrosion, which will reduce the life of the concrete pipes over time, thus affecting their overall performance.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and an anti-permeability reinforced concrete pipe is provided, in order to achieve a purpose with greater practical value. Utility Model Content

[0005] The purpose and effect of the anti-seepage reinforced concrete pipe of the utility model are achieved by the following specific technical means:

[0006] A permeation-proof reinforced concrete pipe comprises long steel bars and circular hoops, wherein the long steel bars are welded equidistantly between the inner walls of the circular hoops, the inner walls of an adjacent pair of circular hoops are provided with installation grooves, reinforcing steel bars are inserted and installed between the installation grooves, the long steel bars, circular hoops and reinforcing steel bars constitute a reinforced concrete pipe as a whole, and an anti-corrosion layer, a reinforcement layer one, a reinforcement layer two and an anti-permeation layer are cast in sequence.

[0007] Furthermore, the anti-corrosion layer is composed of epoxy asphalt material, and the overall thickness is 2-4 cm.

[0008] Furthermore, the reinforcement layer is formed by mixing cement and coarse-grained stone.

[0009] Furthermore, the second reinforcement layer is formed by mixing self-stressed cement and fine stone.

[0010] Furthermore, the anti-seepage layer is formed by pressing geotextile, geomembrane, waterproof board and waterproof blanket through a compound machine, and is bonded to the side wall of the second reinforcement layer by adhesive.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] The utility model can effectively prevent moisture in the soil from corroding the outside of the concrete pipe through the anti-corrosion layer formed by the epoxy asphalt material, thereby improving the overall airtightness of the concrete pipe and preventing leakage; through the design of the anti-permeation layer, it can effectively prevent the medium inside the concrete pipe from corroding and damaging the inner wall of the concrete pipe, thereby effectively improving the overall stability. The above two design methods can form two layers of internal and external protection measures for the concrete pipe, thereby improving the overall stability of the concrete pipe and preventing penetration.
