Description

Technical Field

[0001] This utility model relates to the field of drainage pipes, and in particular to a concrete drainage pipe with high compressive strength. Background Technology

[0002] Concrete drainage pipes are made of cement, sand and gravel aggregates, steel bars and other materials through mixing, molding and curing. They typically include the pipe body, joints and necessary reinforcement structures.

[0003] Concrete drainage pipes are commonly used in municipal and water conservancy projects to transport rainwater and sewage. They are characterized by high compressive strength, good durability, and low cost.

[0004] However, most drainage pipes use simple socket connections or flat butt joints, relying solely on materials such as cement mortar for sealing. During the connection process, the connection may tilt and loosen. Even after sealing with cement, the connection is prone to loosening and disconnection due to factors such as foundation settlement and groundwater erosion during long-term use. Therefore, a concrete drainage pipe with high compressive strength is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a concrete drainage pipe with high compressive strength, which aims to improve the problems in the existing technology where the connection tilts and loosens during the docking process, and is then sealed with cement, and is affected by factors such as foundation settlement and groundwater erosion during long-term use.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a concrete drainage pipe with high compressive strength, comprising a concrete pipe body, wherein a mounting base is fixedly connected to the front end surface of the concrete pipe body, and a reinforcing and sealing component is provided on the outer arc surface of the mounting base;

[0007] The reinforced sealing assembly includes a rotating disk with a through-sloping groove on its surface. A protruding rod is slidably connected to the inner wall of the groove. A positioning screw is threaded through and connected to the outer arc surface of the rotating disk. An insert block is fixedly connected to the outer wall of the protruding rod. An arc groove is formed at the rear end of the concrete pipe. A sealing ring is detachably installed on the inner wall of the arc groove at the rear end of the concrete pipe. A retaining groove is formed at the rear end of the concrete pipe. A slider is slidably connected to the inner side wall of the retaining groove at the rear end of the concrete pipe. A contact block is fixedly connected to the outer wall of the slider.

[0008] As a further description of the above technical solution:

[0009] The inner and outer arc surfaces of the concrete pipe are both fixedly connected with reinforcing rings, and multiple sets of triangular reinforcing ribs are fixedly connected to the outer walls of the two sets of reinforcing rings.

[0010] As a further description of the above technical solution:

[0011] The outer arc surface of the mounting base is provided with a circular groove, and the rotating disk is rotatably connected to the surface of the circular groove of the mounting base.

[0012] As a further description of the above technical solution:

[0013] The inner sidewall of the mounting base is provided with a guide groove, and the protruding rod passes through and is slidably connected to the inner wall of the guide groove.

[0014] As a further description of the above technical solution:

[0015] The insert is slidably connected to the inner side wall of the mounting base, and the bottom end of the outer wall of the insert contacts the inner wall of the rear end slot of the concrete pipe.

[0016] As a further description of the above technical solution:

[0017] The outer arc surface of the mounting base circular groove is provided with two sets of internal threaded grooves, and the positioning screw is threadedly connected to the inner wall of the internal threaded groove.

[0018] As a further description of the above technical solution:

[0019] The contact block is triangular, with the bottom end of the outer wall of the insert contacting one side of the inclined surface of the contact block, and the other side of the inclined surface of the contact block contacting the inner arc surface of the sealing ring.

[0020] As a further description of the above technical solution:

[0021] The triangular reinforcing ribs are provided in multiple sets, and the triangular reinforcing ribs are triangular in shape and evenly distributed on the outer sidewall of the reinforcing ring. The triangular reinforcing ribs are fixedly connected to the outer arc surface and the inner arc surface of the concrete pipe body respectively.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, during pipe installation, simply rotating the rotating disc allows the insert to be precisely inserted into the slot, firmly splicing adjacent pipes. The locking design of the positioning screw further enhances the stability of the connection, effectively resisting foundation settlement and water flow impact. At the same time, the downward pressure of the insert pushes the contact block to move laterally, causing the sealing ring to be pushed outward, forming a multi-seal structure, significantly improving the sealing effect, preventing sewage leakage, ensuring the long-term stable operation of the drainage system, and reducing subsequent maintenance costs.

[0024] 2. In this utility model, the symmetrically distributed reinforcing rings and triangular reinforcing ribs on the inner and outer sides of the concrete pipe construct a stable mechanical support system. Utilizing the structural stability principle of triangles, external pressure can be evenly distributed throughout the entire pipeline. When subjected to external forces such as soil pressure and vehicle loads, this structure effectively reduces the risk of pipeline deformation and cracking. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0033] Reference Figures 1-3An embodiment of this utility model provides a concrete drainage pipe with high compressive strength, including a concrete pipe body 1. A mounting seat 2 is fixedly connected to the front end surface of the concrete pipe body 1. A groove is opened on the inner side of the mounting seat 2 and fits with the rear end of the concrete pipe body 1, so that the two sets of concrete pipe bodies 1 can be installed by fitting together. A reinforcing sealing component 3 is provided on the outer arc surface of the mounting seat 2.

[0034] Reference Figures 2-4 The reinforced sealing assembly 3 includes a rotating disk 31. A circular groove is formed on the outer arc surface of the mounting base 2. The rotating disk 31 is rotatably connected to the surface of the circular groove in the mounting base 2. A cavity is formed at the center of the rotating disk 31, fitting into the circular groove of the mounting base 2, allowing the rotating disk 31 to rotate within the circular groove of the mounting base 2. A through-hole oblique groove is formed on the surface of the rotating disk 31. A protruding rod 32 is slidably connected to the inner wall of the oblique groove. A guide groove is formed on the inner side wall of the mounting base 2. The protruding rod 32 passes through and is slidably connected to the inner wall of the guide groove. An oblique groove is formed on the surface of the protruding rod 32. The protruding rods 32 slide on the inner wall of the vertical groove of the mounting base 2, so that when the rotating disk 31 rotates, the three sets of protruding rods 32 slide up and down on the inner wall of the vertical groove of the mounting base 2. The outer arc surface of the rotating disk 31 is threaded and connected to the positioning screw 33. The outer arc surface of the circular groove of the mounting base 2 is provided with two sets of internal thread grooves. The positioning screw 33 is threaded to the inner wall of the internal thread groove. The threaded connection between the two allows the rotating disk 31 to rotate so that the three sets of protruding rods 32 can drive the insert block 34 to descend and insert into the inner wall of the rear mounting groove of the concrete pipe body 1, and fix the position after disengagement.

[0035] Reference Figure 3 and Figure 4A plug 34 is fixedly connected to the outer wall of the protruding rod 32. When the protruding rod 32 is rotated by the rotating disk 31, it will drive the plug 34 to move up and down synchronously. The plug 34 passes through and is slidably connected to the inner side wall of the mounting base 2. The bottom end of the outer wall of the plug 34 contacts the inner wall of the slot at the rear end of the concrete pipe body 1. The contact between the two allows the plug 34 to engage with the slot when the rear end of another set of concrete pipe bodies 1 is inserted into the mounting base 2, thereby splicing and fixing the two sets of concrete pipe bodies 1. The rear end of the concrete pipe body 1 has an arc groove. A sealing ring 6 is detachably installed on the inner wall of the arc groove at the rear end of the concrete pipe body 1. The sealing ring 6 is existing technology. The sealing ring 6 can seal the position after the other set of concrete pipe bodies 1 is inserted into the mounting base 2, thereby preventing During daily use, water seepage may occur. A groove is provided at the rear end of the concrete pipe body 1. A slider 35 is slidably connected to the inner side wall of the groove at the rear end of the concrete pipe body 1. A contact block 36 is fixedly connected to the outer wall of the slider 35. The contact block 36 is triangular. The bottom end of the outer wall of the insert block 34 contacts one side of the inclined surface of the contact block 36, and the other side of the inclined surface of the contact block 36 contacts the inner arc surface of the sealing ring 6. When the insert block 34 is inserted into another set of grooves at the rear end of the concrete pipe body 1, its bottom end contacts the inclined surface of the contact block 36, thereby pushing the contact block 36 to move laterally on the inner wall of the rear end of the concrete pipe body 1, thus contacting the bottom end of the sealing ring 6. This pushes the sealing ring 6 outward, increasing the tightness of contact with the inner side of the mounting base 2, resulting in a better overall sealing effect.

[0036] Reference Figure 1 and Figure 5 The inner and outer arc surfaces of the concrete pipe body 1 are both fixedly connected with reinforcing rings 4. Multiple sets of triangular reinforcing ribs 5 are fixedly connected to the outer walls of the two sets of reinforcing rings 4. The triangular reinforcing ribs 5 are triangular in shape and are evenly distributed on the outer sidewall of the reinforcing rings 4. The multiple sets of triangular reinforcing ribs 5 are fixedly connected to the outer and inner arc surfaces of the concrete pipe body 1 respectively. By setting multiple sets of triangular reinforcing ribs 5 and distributing them symmetrically on the outer and inner arc surfaces of the concrete pipe body 1, the overall pressure resistance of the pipeline is increased.

[0037] Working principle: The groove on the inner side of the mounting base 2 fits with the rear end of the concrete pipe body 1, allowing the two sets of concrete pipe bodies 1 to be installed by sleeve connection. The rotating disk 31 in the reinforcing sealing assembly 3 is rotatably connected in the circular groove on the outer arc surface of the mounting base 2. The surface of the rotating disk 31 has a through inclined groove, and the inner wall of the inclined groove is slidably connected to the protruding rod 32. The protruding rod 32 also passes through and is slidably connected to the guide groove on the inner side wall of the mounting base 2. When the rotating disk 31 is rotated, due to the cooperation between the inclined groove of the rotating disk 31 and the protruding rod 32, and the sliding restriction of the protruding rod 32 in the guide groove of the mounting base 2, the rotation of the rotating disk 31 will drive the three sets of protruding rods 32 to slide up and down on the inner wall of the guide groove of the mounting base 2. The insert 34 fixed on the outer wall moves up and down synchronously with the protruding rod 32. When the rear end of another set of concrete pipes 1 is inserted into the mounting base 2, the rotating disk 31 is rotated to make the protruding rod 32 drive the insert 34 to descend. The bottom end of the outer wall of the insert 34 is inserted into the inner wall of the slot at the rear end of the concrete pipe 1, realizing the splicing and fixing of the two sets of concrete pipes 1. To ensure a stable connection, the rotating disk 31 is threaded with a positioning screw 33. The outer arc surface of the circular groove of the mounting base 2 is provided with two sets of internal thread grooves. After the insert 34 is inserted into the slot and the splicing is completed, the positioning screw 33 is rotated to make it threadedly connected with the internal thread groove, fixing the rotating disk 31, thereby locking the position of the protruding rod 32 and the insert 34 to prevent the connection from loosening.

[0038] At the same time, when the insert block 34 descends, it exerts a thrust on the inclined surface of the contact block 36, pushing the contact block 36 to move laterally on the inner wall of the rear end of the concrete pipe body 1. The inclined surface on the other side of the contact block 36 contacts the inner arc surface of the sealing ring 6. As the contact block 36 moves, it pushes the sealing ring 6 outward, making the contact between the sealing ring 6 and the inner side of the mounting base 2 tighter, further enhancing the sealing effect and effectively preventing water leakage from the pipeline during daily use.

[0039] Reinforcing rings 4 are fixedly connected to both the inner and outer arc surfaces of the concrete pipe body 1. Multiple sets of triangular reinforcing ribs 5 are fixed to the outer walls of the two sets of reinforcing rings 4. The triangular reinforcing ribs 5 are triangular in shape and evenly distributed on the outer sidewall of the reinforcing rings 4. They are fixed to the inner and outer arc surfaces of the concrete pipe body 1 respectively, and are symmetrically distributed from left to right. Triangles have stability. The multiple sets of triangular reinforcing ribs 5 and reinforcing rings 4 work together to form a stable mechanical structure. When the pipe is subjected to external pressure, the triangular reinforcing ribs 5 and reinforcing rings 4 can evenly distribute the pressure to various parts of the concrete pipe body 1, effectively resisting external pressure, reducing the risk of pipe deformation and damage, thereby significantly improving the overall compressive strength of the concrete drainage pipe and extending its service life.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is 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 described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
