[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0023] Refer to Figures 1-3 , an embodiment provided by the present invention: A steel cylinder concrete pipe includes a cylinder 10, and the cylinder 10 bears internal and external pressures and stresses. One end of the embedded bolt 13 is fixedly connected to the inside of the cylinder 10. The embedded bolt 13 serves to connect the nut 14. The outer wall of the embedded bolt 13 is provided with threads, and a nut 14 is arranged on the outer wall of the embedded bolt 13. The inner wall of the nut 14 is provided with threads, and the inner wall of the nut 14 can be meshed with the outer wall of the embedded bolt 13. The top of the nut 14 penetrates through the hook ring 4. The hook ring 4 serves to connect fastening instruments. The end of the hook ring 4 is fixedly connected to a limiting plate 15. The limiting plate 15 serves to limit the movement of the nut 14. A through hole is opened at the top of the nut 14. The diameter of the through hole is larger than the diameter of the hook ring 4 and smaller than the diameter of the limiting plate 15. Thus, it can be ensured that the nut 14 will not move downward beyond the limiting plate 15. The hook ring 4 is in an n shape, and nuts 14 are arranged at both ends of the n shape. Thus, the hook ring 4 can be more stably fixed on the surface of the cylinder 10. One hook ring 4 is arranged on each of the front and rear sides of the cylinder 10. Thus, it is more convenient for the construction of fastening machinery. Connecting structures are fixedly connected to the front and rear of the cylinder 10. Through the connecting structures, the steel cylinder concrete pipes can be connected tightly. An anticorrosion layer 11 is arranged on the inner wall of the cylinder 10. The anticorrosion layer 11 serves to increase the corrosion resistance of the cylinder 10 and reduce the wear of the cylinder 10. A bonding layer 12 is arranged on the outer wall of the cylinder 10. The bonding layer 12 serves to increase the adhesion between the cylinder 10 and the concrete layer 7. The concrete layer 7 is arranged on the outer wall of the bonding layer 12. The concrete layer 7 serves to provide additional compressive capacity and enhance the overall structural stability of the pipeline. A waterproof layer 2 is arranged on the outer wall of the concrete layer 7. The waterproof layer 2 serves to prevent the external environment from eroding the concrete layer 7.
[0024] The connection structure includes a female steel cylinder head 3 and a male steel cylinder head 5. The male steel cylinder head 5 can be inserted into the female steel cylinder head 3. A sealing ring 6 is fixedly connected to the outer wall of the male steel cylinder head 5. The sealing ring 6 plays a role in isolation, enabling the connection between the male steel cylinder head 5 and the female steel cylinder head 3 to be tighter. The diameter of the female steel cylinder head 3 is larger than that of the male steel cylinder head 5, thus enabling the male steel cylinder head 5 to be correspondingly inserted.
[0025] A cable groove 1 is provided on the outer wall of the concrete layer 7. The cable groove 1 serves to fix the cable. Rounded corners are provided on both sides of the cable groove 1, thereby facilitating the cable to be snapped in. A waterproof layer 2 is provided inside the cable groove 1, thus ensuring the overall waterproofness of the concrete layer 7.
[0026] There are two cable grooves 1 symmetrically arranged on both sides of the outer wall of the concrete layer 7 with respect to the midpoint of the concrete layer 7, thereby maintaining balance during the hoisting process and ensuring hoisting safety.
[0027] Longitudinal prestressed steel wires 9 are provided inside the concrete layer 7, and transverse prestressed steel wires 8 are provided on the outer wall of the longitudinal prestressed steel wires 9.
[0028] The longitudinal prestressed steel wires 9 and the transverse prestressed steel wires 8 are fixed together by welding, thereby enabling the longitudinal prestressed steel wires 9 and the transverse prestressed steel wires 8 to have high integrity.
[0029] The longitudinal prestressed steel wires 9 and the transverse prestressed steel wires 8 are taken as a group, and there are two groups arranged inside the concrete layer 7, thereby increasing the strength of the concrete layer 7.
[0030] The transverse prestressed steel wires 8 are arranged in a spiral shape on the outer wall of the longitudinal prestressed steel wires 9, thus avoiding excessive truncation of the transverse prestressed steel wires 8 and further improving integrity.
[0031] Working principle: Insert the hoisting cable into the middle of the cable groove 1, use a crane to lift the steel cylinder concrete pipe through the cable, and then place it at the predetermined location. Then hoist the second steel cylinder concrete pipe in front of the first section, making the male steel cylinder head 5 of the first steel cylinder concrete pipe correspond to the female steel cylinder head 3 of the second steel cylinder concrete pipe. Then turn the nut 14 to fix the hook 4 on the upper part of the female steel cylinder head 3. Then connect the hooks 4 of the first and second steel cylinder concrete pipes respectively through fastening devices, and pull the two steel cylinder concrete pipes closer through the fastening devices, thereby achieving the connection work.
[0032] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
