[0035] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0036] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0037] Reference Figures 1 to 5 As shown, the present invention provides a pipeline protection device with a settlement adjustment function, comprising: a support frame 1, a supporting round rod 2, a bearing plate 3, a counterweight 4 and a leveling component.

[0038] There are two support frames 1. The two support frames are arranged along the length direction of the pipeline laying path and are arranged below the pipeline.

[0039] Specifically, the support frame 1 includes two columns 11 and a crossbeam assembly 12 .

[0040] The column 11 is a hollow steel column.

[0041] The length of the cross beam assembly 12 is adjustable. The two sides of the cross beam assembly 12 are respectively installed on the top ends of the two columns 11 in a flippable manner.

[0042] The supporting round rod 2 is arranged along the length direction of the pipeline laying path. The supporting round rod 2 is arranged directly below the pipeline. The supporting round rod is arranged directly below the pipeline.

[0043] The two ends of the supporting round rod 2 are rotatably mounted with upper supports 21. The upper supports are provided with shaft holes. The two ends of the supporting round rod are rotatably mounted in the shaft holes of the two upper supports through bearings.

[0044] The upper supports 21 at both ends of the supporting round rod 2 are respectively installed on the crossbeam components 12 of the two supporting frames 1 through slewing bearings.

[0045] The bearing plate 3 is installed on the upper part of the supporting round rod 2. The bearing plate 3 is used to support the pipeline. In this embodiment, the bearing plate and the supporting round rod are arranged in the same direction. A through groove is formed on the upper part of the bearing plate 3. The groove wall of the through groove is arc-shaped. The curvature of the groove wall of the through groove is adapted to the curvature of the outer wall of the pipeline. Vertical brackets are formed on opposite sides of the bearing plate. The vertical brackets on opposite sides of the bearing plate are connected to protective brackets. The protective brackets, the vertical brackets and the bearing plate are enclosed to form a protective space for the pipeline to pass through.

[0046] The counterweight 4 is installed at the lower part of the supporting round rod 2. The weight of the counterweight 4 is greater than the weight of the components at the upper part of the supporting round rod 2 so that the pipeline laid on the bearing plate 3 is always on the pipeline laying path.

[0047] In this embodiment, the counterweight comprises a rod attachment sleeve and a counterweight bar. The rod attachment sleeve is sleeved in the middle of the supporting round rod. The counterweight bar is detachably mounted on the outside of the rod attachment sleeve. Under the action of the self-weight of the counterweight bar, the upper bearing plate of the supporting round rod is always kept horizontal.

[0048] In this embodiment, in the initial stage of erecting the support frame, a heavy counterweight bar is used to quickly compact the foundation, which is beneficial for the lower end of the column to contact the foundation surface more firmly, compacting the ground and reducing the subsequent settlement depth.

[0049] After erection, the speed of settlement can be slowed down by replacing the counterweight bar with a lighter one to avoid the acceleration effect caused by the settlement speed of the support frame.

[0050] The leveling assembly includes an electric jacking member 51, a level and a controller. The electric jacking member 51 is placed between the column 11 and the foundation. The level is installed on the beam assembly 12. The controller is connected to the electric jacking member 51 and the level.

[0051] The level gauge collects the levelness of the beam assembly. The controller obtains the levelness of the level gauge and calculates the height to be raised of the column based on the levelness.

[0052] After the foundation settles, the controller obtains the level of the beam assembly 12 collected by the spirit level and turns on the electric jacking component 51 based on the level to lift the column 11, so that the beam assembly 12 returns to a horizontal setting. After the beam assembly 12 returns to a horizontal setting, a height compensation component is placed under the electric jacking component 51.

[0053] As a preferred implementation, see Figure 2 As shown, the crossbeam assembly 12 includes three sections of beam plates 121 and a movable sleeve 122 .

[0054] The three sections of beam plates 121 are arranged in a colinear or coaxial manner. The ends of two adjacent sections of beam plates 121 can be movably inserted into the two ends of the movable sleeve 122 .

[0055] In this embodiment, two ends of the beam plate of the middle section are fixedly connected to two movable sleeves, and the other two sections of the beam plate are movably inserted into the opposite ends of the two movable sleeves.

[0056] After the foundation on one side of the support frame settles, the beam plate on this side of the support frame slides toward the outside of the movable sleeve.

[0057] The bottom of the beam plate 121 at both ends of the beam assembly 12 is formed with a hinge groove arranged along the length direction of the pipeline laying path. Specifically, the bottom of the beam plate at both ends of the beam assembly is formed with the hinge groove. The top of the column 11 is fixed with a hinge shaft 113. The hinge shaft 113 is rotatably embedded in the hinge groove.

[0058] Continue reading Figure 2 , Figure 4 and Figure 5 The lower end of the column 11 is formed with a buttress 111. The bottom of the buttress 111 is formed with a vertically arranged guide hole. The upper part of the electric lifting member 51 is movably inserted into the guide hole.

[0059] In this embodiment, the electric lifting member 51 is a hydraulic cylinder.

[0060] Continue reading Figure 4 and Figure 5 , two opposite sides of the buttress 111 are respectively formed with receiving grooves, and a reaction plate 112 is movably received in the receiving groove.

[0061] After the electric jacking member 51 lifts the column 11, one side of the reaction plate 112 extends to the outside of the pier 111, and a temporary support is arranged between the reaction plate 112 and the foundation. After the electric jacking member 51 shrinks, the height compensation member is arranged between the shrunken electric jacking member 51 and the foundation and the temporary support is removed.

[0062] In this embodiment, the level is an electronic level.

[0063] When settlement occurs, the level gauge will follow the inclination of the beam assembly, and the level gauge will display the inclination angle. The controller can determine the height of the lower column to be raised by starting the electric jacking member according to the distance an inclination angle between the two columns, so that the beam assembly 2 can be restored to the level, thereby facilitating the adjustment of the column height when the lighting above the support frame is poor.

[0064] The present invention provides a construction method of a pipeline protection device with a settlement adjustment function, comprising the following steps:

[0065] S1: Install two support frames 1 on the foundation below the pipeline, so that the two support frames 1 are along the length direction of the pipeline laying path.

[0066] S2: The upper supports 21 at both ends of the supporting round rod 2 are respectively installed on the crossbeam assemblies 12 of the two supporting frames 1 through slewing bearings, so that the supporting round rod 2 is arranged along the length direction of the pipeline laying path.

[0067] S3: Install the bearing plate 3 on the upper part of the supporting round rod 2 so that the bearing plate 3 is supported on the pipeline.

[0068] S4: After the foundation settles unevenly, causing the column 11 on one side of the support frame 1 to sink, one end of the beam assembly 12 of the support frame 1 flips downward, and the counterweight 4, under the action of its own weight, keeps the bearing plate 3 in a horizontal state at all times, thereby ensuring that the pipeline laid on the bearing plate 3 is always on the pipeline laying path.

[0069] S5: The controller of the leveling assembly obtains the horizontality of the beam assembly 12 after flipping collected by the spirit level and activates the electric lifting member 51 based on the horizontality to lift the column 11 so that the beam assembly 12 is restored to a horizontal setting.

[0070] S6: After the crossbeam assembly 12 is restored to a horizontal position, a height compensation member is placed under the electric lifting member 51 so that the tops of the two columns 11 of each support frame 1 are flush.

[0071] The pipeline protection device with settlement adjustment function of the present invention protects the device from the influence of settlement through the coordinated cooperation of the counterweight and the leveling component, so that the pipeline will not be displaced to a large extent when the ground settles, and maintains stability. At the same time, it avoids tilting and damage when the ground settles, and reduces the influence of ground settlement on the device. The pipeline protection device with settlement adjustment function of the present invention, after the ground settles, sets a leveling component to lift and reset the column, avoiding the difficulty of moving up after settlement, thereby realizing flexible protection of the pipeline and ensuring the smooth construction of the open-cut subway station.
