It is a special plan for the comprehensive optimization of the functions and engineering layout of water sources, water supply systems and drainage systems, and an important part of urban professional functional planning.

[0003] The demand for drainage pipes is increasing accordingly. Traditional reinforced concrete water supply and drainage pipes suffer from low strength and high material costs, failing to meet the high requirements of modern industry. Therefore, researching a water supply and drainage pipe that is high in strength, has high overall durability, saves material costs, and is easy to install is of significant practical importance.

[0004] Therefore, there is an urgent need for a new technical solution to address this problem. Utility Model Content

The 3D steel truss and the reinforcing steel bars are used in the pipe construction. After welding, concrete is poured.

[0007] The 3D steel truss adopts a straight 3D steel truss circumferentially equidistant laying method. The upper chord of the straight 3D steel truss is close to the outer wall of the pipe, and the lower chord of the straight 3D steel truss is close to the inner wall of the pipe. The circumferential spacing of the straight 3D steel truss is 0mm-400mm. Circular reinforcing bars are welded at equal intervals on the upper chord, the lower chord, or the upper and lower chords. The spacing of the circular reinforcing bars is 35mm-120mm, and the diameter of the circular reinforcing bars is not less than 4mm.

[0008] The 3D steel truss adopts a straight 3D steel truss circumferentially equidistant laying method. The upper chord of the straight 3D steel truss is close to the inner wall of the pipe, and the lower chord of the straight 3D steel truss is close to the outer wall of the pipe. The circumferential spacing of the straight 3D steel truss is 0mm-400mm. Circular reinforcing bars are welded at equal intervals on the upper chord, the lower chord, or the upper and lower chords. The spacing of the circular reinforcing bars is 35mm-120mm, and the diameter of the circular reinforcing bars is not less than 4mm.

[0009] The 3D steel truss adopts an axially equidistant laying method. The upper chord of the 3D steel truss is close to the inner wall of the pipe, and the lower chord of the 3D steel truss is close to the outer wall of the pipe. The axial spacing of the 3D steel truss is 0mm-120mm. Straight reinforcing bars are welded at equal intervals on the upper chord, the lower chord, or the upper and lower chords.

[0012] Through the above design scheme, this utility model can bring the following beneficial effects:

[0013] 1. High strength and high overall durability: By laying straight 3D steel trusses in the inner circumference of the pipeline or laying ring-shaped 3D steel trusses in the axial direction, and then welding ring-shaped reinforcing bars or straight reinforcing bars on the corresponding steel trusses, the strength and density of the concrete are greatly enhanced, the cracking problem is solved, and the overall durability of the pipeline is greatly improved.

[0014] 2. High impermeability: By installing a sealing ring between the socket and spigot, the connection device has self-positioning during installation. The ring is evenly stressed, ensuring good joint sealing and adaptability to various water qualities. It guarantees that the joint will not leak due to thermal expansion and contraction of the pipe body, thus ensuring the impermeability of the pipe joint.

[0015] 3. Material saving: By setting 3D steel trusses in the concrete and implementing the T / SDBMIA-007-2021 standard, a special triangular mechanical structure is adopted, which saves about 50% of steel reinforcement material under the same strength.

[0016] 4. Easy installation: The socket connection method simplifies the installation process and makes construction convenient. No welding is required during pipeline laying, eliminating the need to dig trenches at corresponding positions on the foundation. No special foundation treatment is required, which improves installation efficiency and reduces construction costs by about 15%. Attached Figure Description
