Description

Technical Field

[0001] This utility model relates to the field of cement pipe technology, and in particular to an internally reinforced spiral cement pipe. Background Technology

[0002] Cement pipes, also known as cement pressure pipes or reinforced concrete pipes, are a common building material widely used in urban construction, farmland irrigation, and factory drainage. They are primarily made of cement, reinforcing steel, and aggregates. The process involves mixing cement, aggregates, and other materials in a specific ratio to create concrete, then adding reinforcing steel to enhance its strength and toughness. Finally, the pipes undergo molding and curing processes.

[0003] Currently, cement pipes require internal support through a steel reinforcement cage. However, the steel reinforcement cages used in existing cement pipes lack sufficient structural strength, making them prone to breakage or bending under significant pressure or external forces, thus reducing their service life. Therefore, we propose an internally reinforced spiral-reinforced cement pipe. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an internally reinforced spiral cement pipe.

[0005] This utility model is achieved by the following technical solution: an internally reinforced spiral rib cement pipe, comprising a cement pipe, wherein a spiral rib is provided inside the cement pipe, an inner straight steel bar is fixedly connected to the inner wall of the spiral rib, a reinforcing ring is fixedly connected to the outer surface of the spiral rib, a first fixing ring is fixedly connected to the inner wall of the inner straight steel bar, a reinforcing rib is fixedly connected to one end of the first fixing ring, and a second fixing ring is fixedly connected to the end of the reinforcing rib away from the first fixing ring.

[0006] Through the above technical solution, the spiral reinforcement is arranged in a spiral shape inside the cement pipe, which can effectively disperse and transmit external pressure. The inner straight steel bars are fixedly connected to the inner wall of the spiral reinforcement, which further enhances the internal structure of the cement pipe, extends the service life of the cement pipe, and thus improves the safety during use.

[0007] As a further improvement to the above solution, the spiral rib has a spiral structure.

[0008] Through the above technical solution, the spiral structure can evenly distribute external pressure along the entire length of the cement pipe, thereby improving the compressive strength and bending strength of the cement pipe.

[0009] As a further improvement to the above scheme, the number of inner straight reinforcing bars is set to several, and the several inner straight reinforcing bars are arranged in a spiral pattern.

[0010] The above technical solution involves setting a number of internal straight steel bars, which are arranged in a spiral pattern to evenly distribute internal stress and improve the overall strength and stability of the cement pipe.

[0011] As a further improvement to the above scheme, the number of reinforcing rings is set to several, and an outer straight steel bar is fixedly connected between two adjacent reinforcing rings.

[0012] Through the above technical solution, the reinforcing ring is fixedly connected to the outer surface of the spiral reinforcement, which can further enhance the stability of the spiral reinforcement. The reinforcing ring can prevent the spiral reinforcement from deforming under stress, thereby improving the overall structural stability of the cement pipe.

[0013] As a further improvement to the above scheme, the number of outer straight reinforcing bars is set to several, and the several outer straight reinforcing bars are arranged in a circumferential distribution with the reinforcing ring as the center.

[0014] The above technical solution, through a number of outer straight steel bars, can evenly distribute internal stress and improve the overall strength and stability of the cement pipe.

[0015] As a further improvement to the above solution, the first fixing ring is located inside the spiral rib.

[0016] As a further improvement to the above scheme, the number of reinforcing ribs is set to three, and the three reinforcing ribs are arranged in a circle with the first fixing ring as the circumference, and the surface of the second fixing ring is fixedly connected to the inner wall of the inner straight steel bar.

[0017] Through the above technical solution, the reinforcing bar is fixedly connected between the first fixed ring and the second fixed ring, which improves the stability of the connection between the first fixed ring and the second fixed ring. At the same time, the reinforcing bar supports the inner straight steel bar, further improving the bending strength of the cement pipe.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] This invention utilizes spiral reinforcement, inner straight steel bars, and reinforcing rings. Specifically, the spiral reinforcement is arranged in a spiral pattern inside the cement pipe, effectively dispersing and transmitting external pressure, thus improving the compressive and bending strength of the cement pipe. The inner straight steel bars connected to the inner wall of the spiral reinforcement further enhance the internal structure of the cement pipe, improving its overall strength and stability. The reinforcing rings fixed to the surface of the inner straight steel bars further enhance the stability of the spiral reinforcement, preventing deformation under stress and extending the service life of the cement pipe.

[0020] This invention, by setting up reinforcing rings, outer straight steel bars, a first fixing ring, reinforcing ribs, and a second fixing ring, specifically by connecting the outer straight steel bars between the reinforcing rings, can further enhance the internal structure of the cement pipe and improve its overall strength. By fixing the inner straight steel bars together with the first and second fixing rings fixed to the inner wall of the inner straight steel bars, the compressive strength and bending strength of the cement pipe can be significantly improved, making it less prone to cracking or deformation when subjected to greater pressure and external forces. The first and second fixing rings are connected together by the reinforcing ribs, enhancing the structural support capacity. The reinforcing ribs also support the inner straight steel bars, further improving the bending strength. Attached Figure Description
