[0021] The utility model provides an extra-large-caliber double-socket double-insert prestressed steel cylinder concrete pipe, comprising a steel cylinder 1 and a concrete pipe body 2, wherein both ends of the concrete pipe body 2 are provided with semi-circular ring sockets 3, both ends of the concrete pipe body 2 are provided with semi-circular ring sockets 4, and semi-circular ring rubber sealing rings 5 are provided in the semi-circular ring sockets 4, the semi-circular ring sockets 4 are arranged opposite to the semi-circular ring sockets 3, and the semi-circular ring sockets 3 are adapted to the semi-circular ring sockets 4, and both ends of the concrete pipe body 2 are further provided with a first O-type rubber sealing ring 6 and a second O-type rubber sealing ring 7, and the first O-type rubber sealing ring is abutted against the outer wall of the semi-circular ring socket 4, and the second O-type rubber sealing ring 7 is abutted against the inner wall of the semi-circular ring socket 4, the steel cylinder 1 is fixedly connected to the concrete pipe body 2, and is located in the concrete pipe body 2, and the concrete pipe and the steel cylinder 1 are integrally formed.
[0022] In this embodiment, by setting the two ends of the concrete pipe body 2 into a double-socket and double-plug structure, the construction efficiency and the stability of the pipeline can be improved. The semi-circular rubber sealing ring 5, the first O-type rubber sealing ring 6 and the second O-type rubber sealing ring 7 can effectively isolate the uneven microstructure and prevent gas or liquid from passing through the sealing surface, thereby achieving a sealing effect.
[0023] Furthermore, the steel cylinder 1 is provided with outer annular reinforcement 8, outer longitudinal reinforcement 9, inner annular reinforcement 10 and inner longitudinal reinforcement 11, and the number of the outer annular reinforcement 8 is fixedly connected to the outer longitudinal reinforcement 9 and sleeved on the outer longitudinal reinforcement 9, the inner annular reinforcement 10 is fixedly connected to the inner longitudinal reinforcement 11 and sleeved on the inner longitudinal reinforcement 11, and the outer annular reinforcement 8, the outer longitudinal reinforcement 9, the inner longitudinal reinforcement 11, the inner annular reinforcement 10 and the steel cylinder 1 are integrally formed.
[0024] In this embodiment, the outer ring reinforcement 8 and the inner ring reinforcement 10 can provide lateral constraints, enhance the shear resistance and torsion resistance of the component, and also improve the overall stability of the component. The outer longitudinal reinforcement 9 and the inner longitudinal reinforcement 11 can withstand tensile or compressive forces, improve the bending resistance and bearing capacity of the component. The above structure can effectively improve the stability between the steel cylinder 1 and the concrete pipe body 2.
[0025] Furthermore, the concrete pipe body 2 is provided with inner annular reinforcement 12 and outer longitudinal reinforcement 13, and the number of both is multiple, the inner annular reinforcement 12 is fixedly connected to the outer longitudinal reinforcement 13, and is sleeved on the outer longitudinal reinforcement 13, and the inner annular reinforcement 12, the outer longitudinal reinforcement 13 and the concrete pipe body 2 are integrally formed.
[0026] In this embodiment, the interaction between the inner annular reinforcement 12 and the outer longitudinal reinforcement 13 improves the bearing capacity of the component, especially when subjected to dynamic loads or impact loads, while also providing torsional resistance and enhancing the overall performance of the structure.
[0027] Furthermore, the extra-large diameter double-socket double-insert prestressed steel cylinder concrete pipe also includes two mouth-protecting steel rings 14, which are respectively fixedly connected to the concrete pipe body 2, and are symmetrically arranged at both ends of the concrete pipe body 2, and are also located on the opposite sides of the corresponding sockets.
[0028] In this embodiment, the mouth guard steel ring 14 can enhance the strength of the pipe mouth and reduce damage caused by external forces; at the pipe connection, the mouth guard steel ring 14 can protect the interface from damage and ensure the stability and sealing of the pipe connection; and it helps to improve the anti-seepage performance of the pipeline, especially when the soil is poor or crossing railways or roads, it can prevent leakage at the interface; at the same time, it is easier to align the pipeline during installation, which simplifies the construction process and improves construction efficiency.
[0029] Furthermore, the mouth guard steel ring 14 is made of alloy structural steel.
[0030] In this embodiment, by using alloy structural steel as the manufacturing material of the mouth guard steel ring 14, the mouth guard steel ring 14 can effectively withstand various forces that the concrete pipe may encounter during installation and use, such as soil pressure, fluid pressure inside the pipe, etc., thereby protecting the pipe end from damage; and the alloy structural steel has good toughness and a low toughness-brittle transition temperature, which means that even under harsh environmental conditions, the mouth guard steel ring 14 is not prone to brittle fracture, ensuring the safe operation of the pipeline system; at the same time, due to the good hardenability of alloy structural steel, a uniform microstructure can be obtained after proper heat treatment. Such material properties enable the mouth guard steel ring 14 to maintain good performance in various environments.
[0031] In this embodiment, by docking two concrete pipes of the present design, first align one end of the two pipes at random, then rotate one of the pipes so that the semicircular ring sockets 4 of the two pipes are aligned with the semicircular ring sockets 3, and then push any one of the pipes so that the semicircular ring sockets 4 are inserted into the semicircular ring sockets 3 of the other pipe, so that the semicircular ring rubber sealing rings 5, the first O-type rubber sealing rings 6 and the second O-type rubber sealing rings 7 of the two pipes are mutually supported to effectively isolate the uneven microstructure and prevent gas or liquid from passing through the sealing surface, thereby achieving a sealing effect. This connection method is simple and convenient, and there is no need to use a large amount of equipment or manpower to turn around the other pipe, thereby improving the efficiency of the pipeline connection and also improving the stability of the pipeline connection.

Ordinary technicians in this field can understand that all or part of the processes of the above embodiment and equivalent changes made according to the claims of the present invention still fall within the scope covered by the utility model.
