[0002] Polyethylene spiral corrugated pipes have excellent hydraulic properties, strong internal and external corrosion resistance, and moderate axial flexibility. They can be used for gravity flow transportation of various corrosive or non-corrosive media and are increasingly widely used in modern construction, such as as buried drainage and sewage pipes in municipal engineering.

[0003] For example, Chinese patent application number CN201020568703.1 discloses a high-density polyethylene spiral corrugated pipe with reinforcing steel strips, including a pipe body made of high-density polyethylene. The inner wall of the pipe body is smooth, and the outer wall is spirally wound with corrugated steel strips. This utility model has a simple and unique structure, high strength, pressure resistance and impact resistance, smooth inner wall, low frictional resistance, large flow rate, long service life, and strong adaptability to uneven settlement of the pipe foundation.

[0004] While the application of high-strength materials in existing technologies can improve local compressive strength, it cannot solve the stress concentration problem caused by settlement at the structural level, and the material cost is high, making it difficult to promote on a large scale. Utility Model Content

[0005] The purpose of this utility model is to provide a settlement-resistant compensation joint structure for water pipelines to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A water pipeline anti-settlement compensation joint structure includes a corrugated pipe, with flanges connected to both ends of the corrugated pipe, and an anti-settlement mechanism provided between the two flanges. The anti-settlement mechanism includes: a support frame connected between the two flanges, a bracket slidably connected to the support frame, and pressure blocks connected to both the left and right sides of the bracket slidably, with the bottom of the pressure blocks being arc-shaped.

[0007] In a preferred embodiment of the present invention, the top of the support bracket is provided with a through hole, the first bracket is V-shaped and slidably connected to the through hole, and the inner cavity of the first bracket abuts against the outer wall of the corrugated pipe.

[0008] In a preferred embodiment of this utility model, two sliders are slidably connected to the top of the support frame, and two inverted "U"-shaped support seats are connected to the top of the support frame. Two support rods are slidably connected to each support seat, and a bracket second is connected to the top of the two support rods. The bracket second is arc-shaped and its inner arc surface abuts against the outer wall of the corrugated pipe.

[0009] In a preferred embodiment of this utility model, the top of the slider is arched, the bottom ends of the two support rods pass through the support base and abut against the top of the slider, and the top of the slider abuts against the bottom of the pressure block.

[0010] In a preferred embodiment of the present invention, the top of the support frame is provided with a sliding groove, and the bottom of the slider is slidably connected in the sliding groove.

[0011] In a preferred embodiment of this utility model, there are three sets of anti-settlement mechanisms, and the three sets of anti-settlement mechanisms are equally spaced on the outer wall of the corrugated pipe.

[0012] In a preferred embodiment of this utility model, each set of anti-settlement mechanisms is provided with two connecting brackets, and the two connecting brackets are respectively connected to the two sliders on opposite sides; the outer walls of the two flanges are slidably connected with sealing caps.

[0013] In a preferred embodiment of this utility model, both connecting brackets are Z-shaped and arranged opposite to each other. The bottom of the support bracket is provided with a movable hole, and the end of the connecting bracket away from the slider passes through the movable hole and is connected to the sealing cover.

[0014] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

[0015] 1. This anti-settlement compensation joint structure for water pipelines, when the pipeline settles, the corrugated pipe is subjected to force, which pushes the bracket one to slide. The bracket one squeezes the slider through the pressure block, causing the slider to move along the slide groove. During the movement of the slider, the support rod will be finely adjusted up and down, so that the bracket two always fits tightly against the outer wall of the corrugated pipe. Through the coordinated sliding and support of multiple components, the stress generated by settlement is distributed throughout the entire anti-settlement mechanism, rather than concentrated in a certain part of the corrugated pipe. Moreover, this structure achieves anti-settlement by optimizing the mechanical transmission path, without relying on high-strength and expensive materials, solving the problem of "relying solely on high-strength materials to improve local pressure resistance, resulting in high costs and difficulty in promotion" in existing technologies.

[0016] 2. This type of anti-settlement compensation joint structure for water pipelines allows the slider to slide when the pipeline settles. The slider will synchronously pull or push the sealing cover through the connecting bracket, ensuring that the sealing cover always fits against the connection between the flange and the joint. Even when the relative positions of the components change due to settlement, it can effectively prevent external water, mud, and other impurities from entering the joint. This prevents impurities from corroding the bellows, flange, or sliding components of the anti-settlement mechanism, and avoids impurity accumulation affecting the sliding performance of the components or damaging the sealing effect of the joint. This ensures the long-term stable operation of the joint and extends its overall service life. Attached Figure Description

[0019] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0020] Please refer to Figure 1-6A settlement-resistant compensation joint structure for a water pipeline includes a corrugated pipe 1, with flanges 2 connected to both ends of the corrugated pipe 1. The flanges 2 at both ends of the corrugated pipe 1 provide a standardized and convenient connection between the joint and the external water pipeline, ensuring a firm connection between the joint and the pipeline, while facilitating installation and subsequent maintenance. An anti-settlement mechanism 3 is provided between the two flanges 2. The anti-settlement mechanism 3 includes a support frame 31 connected between the two flanges 2, with a bracket 32 ​​slidably connected to the support frame 31. The bracket 32 ​​can slide synchronously with the settlement deformation of the corrugated pipe 1, avoiding rigid tension between the bracket 32 ​​and the corrugated pipe 1, and initially alleviating the local stress on the corrugated pipe 1 caused by settlement. Pressure blocks 33 are connected to both sides of the bracket 32, and the bottom of the pressure blocks 33 is arc-shaped. The pressure blocks 33 can smoothly transmit the force when subjected to force, laying the foundation for subsequent stress dispersion.

[0021] In a preferred embodiment of this utility model, the top of the support bracket 31 is provided with a through hole, and the bracket 32 ​​is V-shaped and slidably connected to the through hole. The inner cavity of the bracket 32 ​​abuts against the outer wall of the corrugated pipe 1. The sliding fit between the bracket 32 ​​and the through hole, combined with the wrapping abutment of the corrugated pipe 1 by the V-shaped structure, ensures that the bracket 32 ​​maintains stable contact with the corrugated pipe 1 when it slides with the deformation of the corrugated pipe 1, and will not cause the support to fall off due to sliding, thus ensuring the continuity of the anti-settlement action.

[0022] In a preferred embodiment of this utility model, two sliders 34 are slidably connected to the top of the support frame 31, and two inverted "U"-shaped support seats 35 are connected to the top of the support frame 31. Two support rods 36 are slidably connected to each support seat 35, and a bracket 37 is connected to the top of the two support rods 36. The bracket 37 is arc-shaped and its inner arc surface abuts against the outer wall of the corrugated pipe 1. The arc-shaped bracket 37 and the original bracket 32 ​​form a "double-layer support" structure, which can disperse the settlement stress of the corrugated pipe 1 from a single support point to the sliders. The components 34, 36, and bracket 37 significantly reduce the stress on individual components and improve the overall anti-settlement capability. The arc-shaped bracket 37 fits tightly against the outer wall of the corrugated pipe 1, adapting to the arc-shaped surface of the corrugated pipe 1 and avoiding local support failure caused by the mismatch between the support components and the shape of the corrugated pipe 1. The sliding fit between the support rod 36 and the support seat 35 allows for flexible height adjustment according to the deformation of the corrugated pipe 1, ensuring that the bracket 37 always remains in close contact with the corrugated pipe 1 and will not lose its supporting function due to the settlement and displacement of the corrugated pipe 1.

[0023] In a preferred embodiment of this utility model, the top of the slider 34 is arched, the bottom ends of the two support rods 36 pass through the support base 35 and abut against the top of the slider 34, the top of the slider 34 abuts against the bottom of the pressure block 33, and the abutting cooperation between the slider 34, the pressure block 33, and the support rods 36 allows the sliding action of the bracket 32 ​​to synchronously drive the slider 34 to move and the support rods 36 to rise and fall. The actions of each component are highly coordinated and there will be no action delay or disconnection, further improving the response speed of the anti-settlement mechanism 3 to the deformation of the bellows 1.

[0024] In a preferred embodiment of this utility model, a groove is provided on the top of the support bracket 31, and the bottom of the slider 34 is slidably connected in the groove. The constraint effect of the groove on the slider 34 can reduce the shaking or loosening of the slider 34 during long-term use and extend the service life of the slider 34. At the same time, the stable movement of the slider 34 can also avoid the overall force imbalance of the anti-settlement mechanism 3 caused by the displacement of the slider 34, and improve the long-term reliability of the joint structure.

[0025] In a preferred embodiment of this utility model, there are three sets of anti-settlement mechanisms 3. The three sets of anti-settlement mechanisms 3 are equally spaced on the outer wall of the corrugated pipe 1, which can form uniform support from the circumference of the corrugated pipe 1, avoid stress concentration caused by insufficient support on one side or in a local area, ensure that the corrugated pipe 1 is subjected to balanced force in the circumference direction during settlement, and reduce the risk of the corrugated pipe 1 breaking due to excessive local deformation.

[0026] In a preferred embodiment of this utility model, each anti-settlement mechanism 3 is provided with two connecting brackets 4, and the two connecting brackets 4 are respectively connected to the two sliders 34 on the opposite sides; the outer walls of the two flanges 2 are slidably connected with sealing caps 5, and the sealing caps 5 always maintain a close fit with the flanges 2 when moving with the sliders 34, which can effectively prevent water, mud, sand and debris from entering the joint and improve the stability of the sealing effect.

[0027] In a preferred embodiment of this utility model, both connecting brackets 4 are Z-shaped and arranged opposite to each other. The bottom of the support bracket 31 is provided with a movable hole. The end of the connecting bracket 4 away from the slider 34 passes through the movable hole and is connected to the sealing cover 5. The connecting bracket 4 associates the slider 34 with the sealing cover 5. When the pipe settles and causes the slider 34 to slide, the slider 34 can pull or push the sealing cover 5 synchronously through the connecting bracket 4, so that the sealing cover 5 is always tightly attached to the connection part of the flange 2 and the joint, avoiding the sealing gap caused by the change of the relative position of the components due to settlement, improving the stability of the sealing effect, extending the overall service life of the joint, and reducing the frequency and cost of later maintenance.

[0028] The working principle of this utility model is as follows: First, the joint structure is fixedly connected to the external water supply pipeline through the flange 2. The corrugated pipe 1, as the core flexible connector, is sealed to the two flanges 2 at both ends, providing a basic flexible space for deformation compensation during pipeline settlement. At the same time, three sets of anti-settlement mechanisms 3 are evenly distributed on the outer wall of the corrugated pipe 1. The support frame 31 of each set of anti-settlement mechanisms 3 is fixedly connected to the two flanges 2 at both ends, forming a support frame spanning the flanges 2, providing a stable base for the subsequent movement of the anti-settlement components. At this time, the overall structure is in an initial stable state. When soil settlement occurs in the buried environment, the external settlement stress will be transmitted to the flanges 2 through the water supply pipeline. This causes the bellows 1 to be subjected to axial tension, compression, or radial displacement stress, at which point the structure enters an anti-settlement working state: First, when the bellows 1 deforms due to stress, its outer wall exerts a force on the bracket 32 ​​and bracket 37 that it abuts against; since the bracket 32 ​​is slidably connected to the through hole of the support bracket 31, the deformation of the bellows 1 will directly drive the bracket 32 ​​to slide along the through hole in the corresponding direction; Second, during the sliding of the bracket 32, the pressure blocks 33 on both sides will move synchronously with the bracket 32, and the arc-shaped surface at the bottom of the pressure block 33 interacts with the arched surface at the top of the slider 34, converting the sliding force of the bracket 32 ​​into a pushing or pulling force along the sliding groove direction of the support bracket 31. The force causes the two sliders 34 to slide along the groove towards or away from each other, achieving initial stress dispersion. In the third step, as the sliders 34 slide, the arched surface at their top generates a vertical pushing or pulling force on the bottom of the support rod 36. Since the support rod 36 is slidably connected to the support seat 35, this force pushes the support rod 36 up and down along the sliding hole of the support seat 35, thereby synchronously adjusting the height or position of the top bracket 37. This ensures that the inner arc surface of the bracket 37 remains tightly against the outer wall of the bellows 1, preventing the support from falling off due to deformation of the bellows 1. During this process, the brackets 32 and 37, through the synergy of sliding and support, dissipate the concentrated settlement on the bellows 1. The stress is distributed to multiple components such as the support frame 31, pressure block 33, slider 34, support base 35, and support rod 36. The sliding buffer and rigid support of each component are used to offset the destructive effect of settlement on the bellows 1 and achieve anti-settlement compensation. At the same time, when the slider 34 slides, it will drive the sealing cover 5 to move synchronously along the outer wall of the flange 2 through the connecting bracket 4. This ensures that the sealing cover 5 is always tightly attached to the connection between the flange 2 and the joint. Even when the relative positions of the components change, it can effectively prevent external mud, rainwater and other impurities from entering the joint. This avoids impurities from corroding the bellows 1, flange 2 or jamming the sliding components of the anti-settlement mechanism 3, and ensures the overall sealing performance and long-term stable operation of the joint.
