[0002] A pipeline is a device consisting of pipes, pipe fittings, and valves used to transport gases, liquids, or fluids containing solid particles. Pipelines have a wide range of applications, primarily in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering, and various industrial installations. During pipeline installation, it is necessary to implement anti-settlement measures to ensure the pipelines can be used more effectively.

[0003] Existing anti-settlement devices for sewage pipelines on soft foundations, such as the anti-settlement device for sewage pipelines on soft foundations provided by Chinese utility model patent CN216713266U, have technical defects in their disclosed technical solutions. The solutions can only be adjusted manually and cannot be adaptively adjusted according to the actual settlement of the foundation. Untimely adjustment can easily lead to pipeline damage. Based on the above problems, we propose an anti-settlement device for sewage pipelines on soft foundations. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a pipeline anti-settlement device for sewage pipeline engineering on soft foundations, so as to solve the problem that traditional pipeline anti-settlement devices cannot be adjusted in real time according to the actual settlement, resulting in untimely adjustment and thus pipeline damage.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a pipeline anti-settlement device for sewage pipeline engineering on soft foundation, comprising an installation component, an adjustment component, and a fixing component; the adjustment component is disposed on top of the installation component, and the fixing component is disposed on top of the adjustment component; the installation component includes a base and a fixing plate disposed on the edge of the base; the adjustment component comprises a bottom plate disposed on top of the base, lower swing arms disposed on both sides of the bottom plate, an upper swing arm disposed on top of the lower swing arms, a top plate disposed on top of the upper swing arms, a rotating shaft disposed at the connection between the upper and lower swing arms, a fixing block disposed on the surface of the rotating shaft, a screw rod disposed between the fixing blocks, a winch disposed at both ends of the screw rod, a traction steel cable disposed on the surface of the winch, and a pre-embedded plate disposed at the bottom of the traction steel cable; When the embedded plate moves downwards following the settlement of the soft foundation, the traction cable drives the winch and screw to rotate, and the fixed block moves relative to each other along the screw axis. At this time, the angle between the upper swing arm and the lower swing arm increases, and the height of the top plate rises.

[0006] Preferably, the fixing assembly includes a mounting plate disposed on the top of the top plate, a slide groove disposed on the top surface of the mounting plate, a slide block disposed inside the slide groove and sliding left and right along the slide groove, a sleeve disposed on the top of the slide block, a spring disposed on the inner side wall of the sleeve, and a clamping plate disposed at one end of the spring.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, through the design of installation and adjustment components, ensures that when the soft foundation settles, the embedded plate buried in the soft foundation will settle synchronously with the soft foundation and shift downwards. During the downward movement of the embedded plate, the traction cable moves downwards, which in turn drives the winch to rotate. The rotation of the winch, in turn, drives the screw to rotate. During the rotation of the screw, the fixed block moves relative to the screw axis. At this time, the angle between the upper and lower swing arms increases, the height of the top plate rises, thereby driving the pipeline to rise, offsetting the effects of settlement, adapting to uneven settlement of the soft foundation, preventing pipeline damage caused by settlement, and helping to extend the service life of the pipeline.

[0011] 2. This utility model also improves upon the design of installation and fixing components. The base is circular, and the fixing plates are evenly distributed in a ring around the edge of the base, increasing the contact area with the ground and reducing the risk of settlement. The fixing components can adjust the position of the jacket according to the pipe diameter. The spring and the clamping plate play a buffering and fixing role, while reserving a small amount of dynamic compensation margin for the pipe. While fixing the pipe, it can also ensure that the pipe can move slightly, further actively offsetting the impact of settlement. Attached Figure Description

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments: This utility model relates to a pipeline anti-settlement device for sewage pipeline engineering on soft foundations, comprising an installation component 1, an adjustment component 2, and a fixing component 3; the adjustment component 2 is fixedly connected to the top of the installation component 1, and the fixing component 3 is fixedly connected to the top of the adjustment component 2; the installation component 1 includes a base 101 and a fixing plate 102 fixedly connected to the edge of the base 101. The base 101 serves as the bottom support structure of the device, bearing the entire weight of the upper adjustment component 2 and fixing component 3, distributing the load to prevent its own settlement, and the fixing plate 102 is used to connect with the foundation soil; the adjustment component 2 is fixedly connected to the bottom plate 201 on the top of the base 101, and rotatably connected to the lower swing arms 202 on both sides of the bottom plate 201, and rotatably connected to the lower swing arms 202. The structure includes an upper swing arm 203 at the top of arm 202, a top plate 204 rotatably connected to the top of upper swing arm 203, a rotating shaft 205 rotatably connected to the connection between upper swing arm 203 and lower swing arm 202, a fixing block 206 fixedly connected to the surface of rotating shaft 205, a screw rod 207 screwed between fixing blocks 206, a winch 208 fixedly connected to both ends of screw rod 207, a traction cable 209 wound around the surface of winch 208, and an embedded plate 2010 fixedly connected to the bottom of traction cable 209. The base plate 201 connects the base 101 to the lower swing arm 202 and provides an installation fulcrum for the lower swing arm 202. The lower swing arm 202 and upper swing arm 203 are connected via rotating shaft 205, forming a movable "scissor-type" support. The structure is the actuator for height adjustment. When the foundation settles, the angle between the lower swing arm 202 and the upper swing arm 203 increases, pushing the top plate 204 upward, thereby causing the pipeline to rise synchronously and offsetting the height decrease caused by settlement. The rotating shaft 205, as the connecting hub between the upper swing arm 203 and the lower swing arm 202, allows both to rotate around the shaft, realizing the change of the included angle. It is the key rotating fulcrum. The fixing block 206 is fixed to the surface of the rotating shaft 205 and threadedly connected to the screw 207. It moves along the axial direction as the screw 207 rotates, thereby driving the position change of the rotating shaft 205 and indirectly controlling the included angle between the upper swing arm 203 and the lower swing arm 202. The screw 207 is used to drive the change of the included angle between the upper swing arm 203 and the lower swing arm 202. The winch 208 is fixed at both ends of the screw 207. It drives the screw 207 to rotate through the tension of the traction cable 209. It is the power transmission component that converts the vertical displacement of the foundation settlement into the rotational motion of the screw 207. The traction cable 209 connects the winch 208 and the embedded plate 2010. When the foundation settles, the embedded plate 2010 pulls down the cable, transmitting the tension generated by the settlement to the winch 208, which drives the screw 207 to rotate. It is the "signal transmission line" that triggers the adjustment action. The embedded plate 2010 is pre-embedded in the soft foundation, directly sensing the foundation settlement and moving down with it. It is connected to the traction cable 209 through the connecting ring at the top, converting the settlement displacement into the tension on the cable. It is the "settlement sensor" and power source trigger of the device.When the embedded plate 2010 moves downwards following the settlement of the soft foundation, the traction cable 209 drives the winch 208 and the screw 207 to rotate, and the fixing block 206 moves relative to the screw 207 along its axis. At this time, the angle between the upper swing arm 203 and the lower swing arm 202 increases, and the height of the top plate 204 rises. This utility model, through the design of the installation component 1 and the adjustment component 2, ensures that when the soft foundation settles, the embedded plate 2010 buried in the soft foundation will settle synchronously with the soft foundation and move downwards. During the process, the traction cable 209 moves downward, causing the winch 208 to rotate. The rotation of the winch 208, in turn, causes the screw 207 to rotate. As the screw 207 rotates, the fixed block 206 moves relative to it along the axis of the screw 207. At this time, the angle between the upper swing arm 203 and the lower swing arm 202 increases, and the height of the top plate 204 rises, thereby causing the pipeline to rise. This counteracts the effects of settlement, adapts to uneven settlement in soft foundations, prevents pipeline damage caused by settlement, and helps extend the pipeline's service life.

[0015] Specifically, the fixing component 3 includes a mounting plate 301 fixedly connected to the top of the top plate 204, a groove 302 formed on the top surface of the mounting plate 301, a slide block 303 slidably connected inside the groove 302 and sliding left and right along the groove 302, a sleeve 304 fixedly connected to the top of the slide block 303, a spring 305 fixedly connected to the inner wall of the sleeve 304, and a clamping plate 306 fixedly connected to one end of the spring 305. The mounting plate 301 connects the top plate 204 with the other components of the fixing component 3, providing a mounting surface for the groove 302 and the slide block 303, and transferring the pipe load to the top plate 204. The slide block 303 can slide left and right along the groove 302, facilitating the adjustment of the position of the sleeve 304 according to the pipe diameter, adapting to the installation of pipes of different specifications, and improving the versatility of the device. The sleeve 304 is used to wrap the outside of the pipe and is the main structure for fixing the pipe. Spring 305 is located inside the sleeve 304, connecting the sleeve 304 and the clamping plate 306, and has an elastic buffering effect. The clamping plate 306 is curved and fits against the outer surface of the pipe. Spring 305 and clamping plate 306 allow the pipe to undergo small displacement when the temperature changes or slight deformation occurs, avoiding pipe rupture caused by rigid fixation. This utility model also increases the contact area with the ground and reduces the risk of settlement by designing installation component 1 and fixing component 3. The base 101 is circular and the fixing plate 102 is evenly distributed in a ring on the edge of the base 101. The fixing component 3 can adjust the position of the sleeve 304 according to the pipe diameter. Spring 305 and clamping plate 306 play a buffering and fixing role, while reserving a small dynamic compensation margin for the pipe. While fixing the pipe, it can also ensure that the pipe can move slightly, further actively offsetting the impact of settlement.

[0016] More specifically, a fixing pin is installed on the top of the slide 303, and a pin hole that mates with the fixing pin is opened on the top of the mounting plate 301 to facilitate fixing the slide 303 to the top of the mounting plate 301. A connecting plate is installed on the top of the opposite side of the clamp 304, and a connecting bolt is installed on the connecting plate to facilitate the fixed connection of the two clamps 304. The clamps 304 are semi-circular, and the two clamps 304 can be spliced ​​into a circle to wrap around the outside of the pipe. The clamp 306 is curved to facilitate fitting the pipe surface for clamping and fixing.

[0017] It is worth mentioning that the base 101 is circular, and the circular design can evenly transmit pressure to the foundation, reduce local stress concentration, and adapt to the stress characteristics of soft soil foundation. The fixing plate 102 is evenly distributed in a ring on the edge of the base 101, which increases the contact area and further avoids stress concentration. The top of the fixing plate 102 is provided with matching fixing bolts 103 and fixing screw holes for easy connection with the ground.

[0018] It is worth noting that a limiting sleeve is installed in the middle of the screw 207. The limiting sleeve is used to restrict the position of the fixing block 206. A connecting ring that cooperates with the traction cable 209 is installed on the top of the embedded plate 2010, which facilitates the connection of the embedded plate 2010 with the traction cable 209.

[0019] Working principle: This embodiment provides a pipeline anti-settlement device for sewage pipeline engineering on soft foundations. In use, the base 101 is first placed in a preset position, and the base 101 is fixed to the foundation surface by fixing bolts 103 and fixing screw holes on the fixing plate 102. The fixing bolts 103 are tightened to ensure the stability of the base 101. Then, the embedded plate 2010 is buried in the foundation, and the tension of the traction steel cable 209 is adjusted to make it moderately taut. When the soft foundation settles, the embedded plate 2010 moves downward with the foundation, the traction steel cable 209 is pulled downward, and then drives the winch 208 to rotate. The rotation of the winch 208 causes the screw 207 to rotate accordingly. Since the fixing block 206 is threadedly connected to the screw 207, and the fixing block 206 is connected to the upper swing arm 203 and the lower swing arm 202 respectively via the rotating shaft 205, the rotation of the screw 207 causes the two fixing blocks 206 to move relative to each other along the axis of the screw 207. As the fixing blocks 206 move relative to each other, the included angle between the upper swing arm 203 and the lower swing arm 202 gradually increases, thereby pushing the top plate 204 upward. The rise of the top plate 204 causes the fixing assembly 3 and the sewage pipe to rise together, offsetting the impact of foundation settlement on the pipe and achieving the purpose of preventing the pipe from settling along with the soft foundation.

[0020] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
