Abstract
Description
Technical Field
[0001] This utility model relates to the field of civil engineering technology, specifically to a quick-connecting precast concrete pipe joint device. Background Technology
[0002] In modern infrastructure construction, such as urban water supply and drainage systems, underground utility tunnels, and farmland irrigation projects, precast concrete pipes are widely used due to their advantages of low cost, high strength, and good durability. The quality and efficiency of the connections between pipes directly affect the performance and construction progress of the entire pipeline system.
[0003] Existing technologies have the following drawbacks: Traditional precast concrete pipe connection methods have numerous disadvantages. For example, when using cement mortar joints, the construction process is relatively cumbersome, requiring on-site mortar mixing and demanding high technical skills from construction workers. Furthermore, the setting time of cement mortar slows down construction progress, significantly impacting project speed in projects with tight schedules. Simultaneously, cement mortar joints are susceptible to external environmental factors during long-term use, such as temperature changes and groundwater erosion, leading to cracks and leaks at the joints. This, in turn, affects the sealing and stability of the pipeline system, increasing subsequent maintenance costs.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.
[0022] Reference Figure 1 、 Figure 2 In the embodiment, a prefabricated concrete pipe joint device of quick connection comprises pipeline one 1 and pipeline two 6, the pipeline one 1 and the pipeline two 6 are the same type of pipeline, the pipeline one 1 and the pipeline two 6 are provided with socket 4 at one end, the pipeline one 1 and the pipeline two 6 are provided with socket 3 at the end away from the socket 4, the socket 4 is provided with a plurality of uniformly distributed bolts 5 connected by outer periphery thread, the pipeline one 1 and the pipeline two 6 are provided with a plurality of uniformly distributed threaded holes 7 on the outer periphery, the threaded hole 7 on the outer periphery of the pipeline two 6 is connected with the bolt 5 by thread, and the bolt 5 is provided with gasket 10 on the outer periphery.
[0023] Specifically, the pipeline one 1 is provided with socket 4 at one end, the pipeline two 6 is provided with socket 3 matched with the socket 4 at one end, the socket 3 is provided with round corner on the outer periphery, the inner diameter of the socket 4 is matched with the outer diameter of the socket 3, and the socket 4 is provided with chamfer opening outward, the staff member aims the socket 3 of the pipeline two 6 at the socket 4 of the pipeline one 1, guides by the chamfer of the socket 4 and the round corner of the socket 3, makes the socket 3 smoothly insert into the socket 4, when the socket 3 is inserted into the socket 4 at appropriate position, the bolt 5 is screwed, so that the bolt 5 is connected with the threaded hole on the pipeline two 6 by thread, so that the two pipelines are tightly connected.
[0024] Reference Figure 2 、 Figure 3 and Figure 4In the embodiment, the pipe one 1 and the pipe two 6 are provided with wear-resistant coatings 2 close to the outer periphery of the sockets 3, the sockets 4 on one side of the pipe one 1 are connected with the wear-resistant coatings 2 on one side of the pipe two 6, the inner walls of the pipe one 1 and the pipe two 6 are clamped with elastic sealing rings 8 close to the sockets 4, the elastic sealing rings 8 are composed of EPDM rubber layers in the inner layers and water-swelling waterstop strips in the outer layers, the pipe one 1 and the pipe two 6 are penetrated by a plurality of reinforcing ribs 9 which are evenly distributed, the sockets 4 are provided with chamfers which are open to the outer periphery, the outer periphery of the sockets 3 is provided with round corners, the pipe one 1 and the pipe two 6 are connected with each other, the inner diameter of the socket 4 is matched with the outer diameter of the socket 3.
[0025] Specifically, when the socket 3 is completely inserted into the socket 4, the elastic sealing ring 8 is squeezed between the inner walls of the socket 3 and the socket 4. The EPDM rubber layer in the inner layer is deformed by its elasticity to fill the gap and form the first sealing barrier. If the medium in the pipe or the external underground water seeps into the connection, the water-swelling waterstop strip in the outer layer swells when it meets water, further blocking the gap and forming the second sealing barrier, ensuring the sealing of the connection, and the reinforcing ribs 9 in the pipe one 1 and the pipe two 6 work together to enhance the anti-deformation ability and structural strength of the whole pipe. When the pipe is subjected to external pressure or internal pressure, the reinforcing ribs 9 disperse the stress to prevent the pipe from being broken or deformed, and the pipe two 6 is provided with wear-resistant coatings 2 close to the outer periphery of the socket 3. In the process of inserting the socket 3 into the socket 4, the wear-resistant coatings 2 reduce the frictional resistance between the inner walls of the socket 3 and the socket 4, and prevent the concrete material from falling off due to friction, prolonging the service life of the pipe connection.
