Description

Technical Field

[0001] This utility model belongs to the field of municipal engineering pipeline technology, specifically relating to a cement pipe with a butt joint sealing structure. Background Technology

[0002] Throughout the long history of human urban civilization, cement pipes have served as underground "blood vessels," silently bearing the crucial functions of urban drainage, water supply, and communication, and supporting the orderly operation of modern cities. As early as the Industrial Revolution, with the rapid expansion of urban scale and the large-scale concentration of population, traditional drainage facilities could no longer meet the demand. Cement pipes emerged due to their advantages such as readily available raw materials, relatively simple manufacturing processes, and controllable costs, becoming an important choice for urban infrastructure construction.

[0003] Today, with the continuous acceleration of urbanization, the scale and complexity of underground pipe networks are constantly increasing. The efficient operation of cities places higher demands on the performance of cement pipes. They must not only possess strong compressive strength to withstand surface vehicle loads and soil pressure, but also have excellent sealing and corrosion resistance to prevent sewage leakage and contamination of soil and groundwater, as well as resist erosion by various media. At the same time, cement pipes also play an important role in transportation construction and energy transmission, such as drainage in highways and underground transmission of electricity and gas.

[0004] The rigid connection structure used in the laying of existing cement pipes can easily lead to gaps forming at the joints between two pipe sections due to factors such as construction precision, material properties, or external forces. These gaps become channels for liquid leakage, allowing groundwater to seep into the pipes or sewage to leak into the surrounding environment. Liquid leakage not only affects the normal operation of the pipeline system but may also cause soil erosion, damage the foundation stability, and further lead to safety hazards such as foundation settlement. Utility Model Content

[0005] The purpose of this invention is to provide a cement pipe with a sealing structure for the joint gaps, aiming to solve the problem that existing cement pipes use rigid connection structures during installation, which easily leads to the formation of joint gaps at the joints of two sections of cement pipe due to construction precision, material properties, or external forces. These gaps become channels for liquid leakage, allowing groundwater to seep into the pipes or sewage to leak into the surrounding environment. Liquid leakage not only affects the normal operation of the pipeline system but may also cause soil erosion, damage the foundation stability, and further lead to safety hazards such as foundation settlement.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cement pipe with a butt joint sealing structure, comprising a cement pipe body, a butt joint being formed on one side surface of the cement pipe body, a limiting post being connected to the surface of the butt joint, a first sealing ring being fitted onto the surface of the limiting post, a rectangular groove being formed on the surface of the cement pipe body near the butt joint, a rectangular block being movably inserted into the surface of the rectangular groove, the surface of the rectangular block being connected to the surface of the butt joint, a second sealing ring being fitted onto the open end surface of the butt joint, a slot being formed on the surface of the second sealing ring, a rectangular block being movably inserted into the surface of the slot, and the front end of the second sealing ring abutting against the surface of the first sealing ring.

[0007] As a preferred embodiment of the cement pipe with a butt joint sealing structure of the present invention, the surface of the first sealing ring is provided with four circular through grooves, and the shape and size of the through grooves are adapted to the limiting post.

[0008] As a preferred embodiment of the cement pipe with a butt joint sealing structure according to this utility model, the second sealing ring has a double-layer structure, one side of the second sealing ring is an annular cavity, and the shape and size of the annular cavity are adapted to the butt joint.

[0009] As a preferred embodiment of the cement pipe with a butt joint sealing structure according to this utility model, the slot is a rectangular structure, and its shape and size are adapted to the rectangular block.

[0010] As a preferred embodiment of the present invention, a cement pipe with a butt joint sealing structure is provided, wherein a reinforcing sleeve is connected to the surface of the cement pipe body near the butt joint end, a reinforcing groove is formed on the surface of the reinforcing sleeve, a reinforcing rod is fitted and connected to the surface of the reinforcing groove, and the other side surface of the reinforcing rod is connected to a connecting ring.

[0011] As a preferred embodiment of the present invention, a cement pipe with a butt joint sealing structure is provided, wherein a limiting groove is provided on the inner wall of the connecting ring, the surface of the limiting groove is movably connected to the surface of the limiting rod, and the surface of the limiting rod is connected to the surface of the cement pipe body near the butt joint end.

[0012] As a preferred embodiment of the cement pipe with a butt joint sealing structure of this utility model, the limiting rod is a semi-circular strip structure with rectangular protrusions on both sides.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] Through the mutual cooperation between the cement pipe body, the joint, the limiting post, the first sealing ring, the rectangular groove, the rectangular block, the joint, the second sealing ring and the slot, the connection between the two cement pipe sections is elastically abutted. Thus, through the elastic deformation of the two sets of sealing rings, the joint gap is tightly filled. Even under complex working conditions such as soil settlement and vibration, the sealing state can be maintained continuously, effectively preventing sewage leakage and groundwater intrusion, and improving the sealing performance and stability of the cement pipe connection.

[0015] By utilizing the interplay between reinforcing sleeves, reinforcing grooves, reinforcing rods, connecting rings, limiting grooves, and limiting rods, the intersection area of ​​two connected cement pipes is increased. This allows the connected cement pipes to more evenly distribute the stress generated by settlement, preventing severe deformation or damage to individual pipes due to uneven stress, and improving the pipeline system's resistance to settlement.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5 The present invention provides the following technical solution: a cement pipe with a butt joint sealing structure, comprising a cement pipe body 1, a butt joint 2 opened on one side surface of the cement pipe body 1, a limiting post 3 connected to the surface of the butt joint 2, a first sealing ring 4 sleeved on the surface of the limiting post 3, a rectangular groove 5 opened on the surface of the cement pipe body 1 near the butt joint 2, a rectangular block 6 movably inserted into the surface of the rectangular groove 5, the surface of the rectangular block 6 connected to the surface of the butt joint 7, a second sealing ring 8 sleeved on the open end surface of the butt joint 7, a slot 9 opened on the surface of the second sealing ring 8, the rectangular block 6 movably inserted into the surface of the slot 9, and the front end of the second sealing ring 8 abutting against the surface of the first sealing ring 4.

[0025] Preferably, the surface of the first sealing ring 4 has four circular through grooves, and the shape and size of the through grooves are adapted to the limiting post 3.

[0026] In practical use, the limiting posts 3 distributed in a ring on the surface of the interface 2 at one end of the cement pipe body 1 are used to insert and fix the position of the first sealing ring 4.

[0027] Preferably, the second sealing ring 8 has a double-layer structure, with one side of the second sealing ring 8 forming an annular cavity, and the shape and size of the annular cavity are adapted to the butt joint 7.

[0028] In practical use, the annular cavity on one side of the second sealing ring 8 can be used to tightly fit onto the surface of the connector 7, thereby providing elastic protection and filling of gaps at the intersection of the connector 7 and the interface 2.

[0029] Preferably, slot 9 has a rectangular structure, and its shape and size are adapted to rectangular block 6.

[0030] In practical use, the slot 9 opened on the surface of the second sealing ring 8 is used to facilitate the precise docking of the rectangular block 6 on the surface of the connector 7, so that the second sealing ring 8 is tightly fitted on the surface of the connector 7 to seal and protect it.

[0031] Preferably, a reinforcing sleeve 10 is connected to the surface of the cement pipe body 1 near the end of the interface 2. A reinforcing groove 11 is formed on the surface of the reinforcing sleeve 10. A reinforcing rod 12 is fitted and connected to the surface of the reinforcing groove 11. The other side of the surface of the reinforcing rod 12 is connected to the connecting ring 13.

[0032] In practical use, the limiting rod 15 provided on the surface of the cement pipe body 1 allows the connecting ring 13, which is slidably connected thereon, to move parallel to the surface of the cement pipe body 1 under the limitation of the limiting groove 14. This allows the reinforcing inserts 12, which are distributed in a ring on the surface of the connecting ring 13, to move toward the cement pipe body 1 that is inserted on the other side, and then insert the reinforcing inserts 12 into the reinforcing groove 11 opened in the reinforcing sleeve 10 connected to the surface of the other section of the cement pipe body 1.

[0033] Preferably, a limiting groove 14 is formed in the inner wall of the connecting ring 13, the surface of the limiting groove 14 is movably connected to the surface of the limiting rod 15, and the surface of the limiting rod 15 is connected to the surface of the cement pipe body 1 near the end of the connector 7.

[0034] In practical use, the limiting groove 14 opened on the surface of the connecting ring 13 allows it to slide and adjust its position on the limiting rod 15, while the limiting rod 15 limits its range of movement.

[0035] Preferably, the limiting rod 15 is a semi-circular strip structure with rectangular protrusions on both sides.

[0036] In practical use, the limiting rod 15 is used to allow the connecting ring 13 to move through the limiting groove 14 while limiting the range of movement of the connecting ring 13.

[0037] Working principle: During municipal construction, when connecting two sections of cement pipe body 1, the first sealing ring 4 is fitted onto the limiting post 3, thereby fixing the connection between the two using the through groove on the first sealing ring 4 that matches the limiting post 3. Then, the rectangular block 6 on the surface of the other cement pipe body 1 is inserted into the slot 9 on the surface of the second sealing ring 8, thereby fixing the position of the second sealing ring 8 on the surface of the joint 7. Then, the rectangular block 6 on the surface of the joint 7 abuts against the rectangular groove 5 on the surface of the other cement pipe body 1, thereby utilizing... The rectangular groove 5 and the rectangular block 6 are fitted together to connect the two sections of cement pipe body 1. At this time, the first sealing ring 4 fitted on the surface of the interface 2 and the second sealing ring 8 fitted on the surface of the joint 7 play a buffering and protective role in the connection between the two sections of cement pipe body 1, avoiding damage to the connection between the two sections of cement pipe body 1 due to rigid connection. At the same time, the first sealing ring 4 and the second sealing ring 8 abut against each other. Through their elastic properties, they can fill and seal the joint gap between the two cement pipe bodies 1, avoiding gaps at the interface, which could lead to sewage seepage and groundwater intrusion.

[0038] Simultaneously, after the open ends of the two cement pipe bodies 1 are inserted together, the limiting rod 15 provided on the surface of the cement pipe body 1 allows the connecting ring 13, which is slidably connected thereon, to move parallel to the surface of the cement pipe body 1 under the limitation of the limiting groove 14. This allows the reinforcing inserts 12, which are distributed in a ring on the surface of the connecting ring 13, to move toward the cement pipe body 1 that is inserted on the other side. The reinforcing inserts 12 are then inserted into the reinforcing groove 11 opened in the reinforcing sleeve 10 connected to the surface of the other cement pipe body 1. This increases the intersection area of ​​the two cement pipe bodies 1 by connecting the reinforcing sleeve 10 and the reinforcing inserts 12. As a result, when subjected to external force, the force can be distributed more evenly, avoiding deformation or damage to the cement pipe body 1 caused by the force on a single pipe or connection.

[0039] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
