Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pipeline engineering, and in particular to a pipeline protection system and a pipeline protection method for controlling deformation of existing pipelines. BACKGROUND

[0002] With the increasing attention of the state to the water environment, the construction amount of various pipe network projects is increasing. For pipe network projects in the city center, the original power, telecommunications, water supply, drainage and other pipelines are complexly distributed on the pipe network line. Therefore, in the construction process of new pipe network projects, a large number of existing pipelines are often involved in protection. For new pipeline construction projects with densely distributed existing pipelines, open excavation method is mainly used for construction. The protection of existing pipelines in the trench range of new pipelines constructed by open excavation method mainly uses suspension method. The suspension method mainly suspends one end of the steel wire rope on the ground channel steel, and suspends the other end of the steel wire rope on the existing pipeline. This method is the most widely used at home and abroad. However, after suspension, it generally appears to be loose, and does not have a tension adjustment function, so the safety hidden danger cannot be guaranteed. During construction, the existing pipeline may be lowered due to the loosening of the steel wire rope, resulting in excessive deformation or damage of the existing pipeline. Once an accident occurs, it will cause slow progress of the project, greater impact on the surrounding environment, and greater construction risk. In addition, after using the traditional suspension protection method, the construction space of the new pipeline is restricted, and the construction efficiency of the new pipeline project is reduced.

[0025] To illustrate the technical content and structural features of the present invention in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0026] Please see Figures 1 to 5 The assembly line protection system 100 for controlling the deformation of existing pipelines of the present invention is used to protect existing pipelines 201 located in pipeline trenches 200. It includes a suspension module 1, a suspension steel cable 2, a lifting and adjusting assembly 3, and a telescopic support assembly 4. The suspension module 1 is movably mounted on the construction ground 300. Both ends of the suspension steel cable 2 are connected to the suspension module 1, suspending the existing pipeline 201. One end of the lifting and adjusting assembly 3 is connected to the suspension module 1, and the other end of the lifting and adjusting assembly 3 is used to support the construction ground 300. 0. The lifting adjustment component 3 drives the suspension frame module 1 and the suspension steel cable 2 to rise together, so that the suspension steel cable 2 lifts the existing pipe 201. The telescopic support component 4 is set in the pipe base trench 200. The telescopic support component 4 detachably supports the existing pipe 201, so that the lifting adjustment component 3 drives the suspension frame module 1 and the suspension steel cable 2 to descend together and release the existing pipe 201. This allows the suspension frame module 1 to move the suspension steel cable 2 to the next suspension position to suspend and protect the existing pipe 201 at another position.

[0027] Please seeFigure 2 In this embodiment, the suspension frame module 1 includes a suspension frame body 11 and a walking component 12. The walking component 12 is disposed at the bottom of the suspension frame body 11 and movably disposed on the construction ground 300. Both ends of the suspension steel cable 2 are connected to the suspension frame body 11, and one end of the lifting adjustment component 3 is connected to the suspension frame body 11. Specifically, the suspension frame body 11 includes a hanger body 111 and a sliding member 112. The sliding member 112 is slidably disposed on the hanger body 111. The walking component 12 is connected to the sliding member 112 and is located below the hanger body 111. Both ends of the suspension steel cable 2 are connected to the hanger body 111, and one end of the lifting adjustment component 3 is connected to the hanger body 111.

[0028] Please see Figure 2 and Figure 3 Furthermore, the suspension frame 11 also includes a sliding adjustment fixing bolt 113. The sliding adjustment fixing bolt 113 passes through the sliding member 112 and is locked to the suspension frame body 111. By releasing the sliding adjustment fixing bolt 113 from the suspension frame body 111, the sliding member 112 can slide along the length direction of the suspension frame body 111. When it is necessary to drive the sliding member 112 to adjust its position, the sliding adjustment fixing bolt 113 is turned to release the sliding adjustment fixing bolt 113 from the suspension frame body 111, thereby driving the sliding member 112 to slide along the length direction of the suspension frame body 111, which in turn drives the traveling assembly 12 and the lifting adjustment assembly 3 to move together. By adjusting the position of the traveling assembly 12 and the lifting adjustment assembly 3, it can adapt to pipe trenches 200 of different widths and sizes. Furthermore, the suspension frame body 111 is provided with a lifting lug 114, through which the suspension frame module 1 can be lifted.

[0029] Please see Figure 3In this embodiment, the walking assembly 12 includes a walking seat 121 and a walking wheel 122. The walking seat 121 is connected to a sliding member 112, and the walking wheel 122 is pivotally connected to the walking seat 121. The walking wheel 122 can walk on the construction ground 300, thereby driving the entire suspension frame module 1, together with the suspension steel cable 2 and the lifting adjustment assembly 3, to move to various suspension positions. Furthermore, the walking assembly 12 also includes a walking fixing bolt 123, which passes through the walking seat 121 and is locked to the walking wheel 122. By releasing the walking fixing bolt 123 from the walking wheel 122, the walking wheel 122 can rotate and walk on the construction ground 300. After the traveling wheel 122 moves the entire suspension module 1, along with the suspension steel cable 2 and the lifting adjustment assembly 3, to the target position, it is locked to the traveling wheel 122 by the traveling fixing bolt 123. This prevents the suspension module 1 and the suspension steel cable 2 from moving when suspending the existing pipeline 201, effectively ensuring the stability of the suspension protection of the existing pipeline 201 by the suspension module 1 and the suspension steel cable 2. When it is necessary for the traveling wheel 122 to move the entire suspension module 1, along with the suspension steel cable 2 and the lifting adjustment assembly 3, to the next suspension position, the traveling fixing bolt 123 is loosened to release the travel fixing bolt 123 from the traveling wheel 122, thus driving the traveling wheel 122 to move.

[0030] Please see Figure 2 and Figure 3 In this embodiment, the lifting adjustment assembly 3 includes a first lifting adjustment bolt 31, a lifting adjustment sleeve 32, and a second lifting adjustment bolt 33 arranged sequentially from top to bottom. The upper end of the first lifting adjustment bolt 31 is fixedly connected to the suspension frame module 1, and the lower end of the first lifting adjustment bolt 31 is inserted into the lifting adjustment sleeve 32 and threadedly connected to the lifting adjustment sleeve 32. The upper end of the second lifting adjustment bolt 33 is inserted into the lifting adjustment sleeve 32 and threadedly connected to the lifting adjustment sleeve 32. The lower end of the second lifting adjustment bolt 33 is used to support the construction ground 300. By rotating and adjusting the lifting adjustment sleeve 32 or the second lifting adjustment bolt 33, the suspension frame module 1 is driven to rise and fall, thereby driving the suspension steel cable 2 to rise and fall together, thereby lifting or releasing the existing pipeline 201.

[0031] Please see Figure 1 and Figure 4In this embodiment, the telescopic support assembly 4 includes, from bottom to top, a first telescopic support bolt 41, a telescopic support sleeve 42, a second telescopic support bolt 43, and an arc-shaped support plate 44. The lower end of the first telescopic support bolt 41 is used to support the bottom of the pipe trench 200, and the upper end of the first telescopic support bolt 41 is inserted into the telescopic support sleeve 42 and threadedly connected to the telescopic support sleeve 42. The lower end of the second telescopic support bolt 43 is inserted into the telescopic support sleeve 42, and the upper end of the second telescopic support bolt 43 is fixedly connected to the arc-shaped support plate 44. The upper part of the arc-shaped support plate 44 is provided with an arc-shaped portion 441 for supporting the existing pipe 201. The height of the entire telescopic support assembly 4 can be adjusted by rotating and adjusting the telescopic support sleeve 42 or the second telescopic support bolt 43. When it is necessary to support the existing pipe 201, the height of the entire telescopic support assembly 4 can be extended and adjusted so that the arc-shaped part 441 of the arc-shaped support plate 44 presses against the existing pipe 201; when it is necessary to remove the telescopic support assembly 4, the height of the entire telescopic support assembly 4 can be shortened so that the arc-shaped part 441 of the arc-shaped support plate 44 is detached from the existing pipe 201.

[0032] Combination Figures 1 to 7 The present invention also provides a method for controlling the deformation of an existing pipeline 201 in a production line, which includes the following steps:

[0033] S1 provides a suspension frame module 1, a suspension steel cable 2, a lifting adjustment component 3 and a telescopic support component 4, connecting both ends of the suspension steel cable 2 to the suspension frame module 1, and connecting one end of the lifting adjustment component 3 to the suspension frame module 1;

[0034] S2, excavate the pipeline trench 200. After the existing pipeline 201 is excavated, the suspension frame module 1 is hoisted onto the pipeline trench 200. The other end of the lifting and adjusting component 3 is supported on the construction ground 300. The suspension steel rope 2 directly suspends the existing pipeline 201.

[0035] S3, excavate the soil layer below the existing pipeline 201, carry out the construction of the new pipeline 202, and monitor the deformation of the existing pipeline 201 at the suspension position in real time.

[0036] S4. Before backfilling the soil layer, if the suspension position of the existing pipeline 201 is deformed, the lifting adjustment component 3 drives the suspension frame module 1 and the suspension steel rope 2 to rise together, so that the suspension steel rope 2 lifts the existing pipeline 201, thereby controlling the deformation of the existing pipeline 201 to its original position and protecting the existing pipeline 201.

[0037] S5, when the newly constructed pipeline 202 is laid and the pipeline trench 200 is backfilled with soil to a certain distance from the suspension point of the suspension steel cable 2 (e.g.) Figure 7As shown in the figure (301 represents the original soil and 302 represents the backfill soil), an expansion joint 4 is arranged near the newly built pipeline 202. The expansion joint 4 can detachably support the existing pipeline 201.

[0038] S6, excavate the next pipeline trench 200, the lifting and adjusting component 3 drives the suspension frame module 1 together with the suspension steel rope 2 to descend and release the existing pipeline 201, push the suspension frame module 1 to move to the position corresponding to the next pipeline trench 200, and the suspension steel rope 2 is suspended and protected at another suspension position of the existing pipeline 201.

[0039] S7, Remove telescopic support assembly 4;

[0040] S8 Repeat steps S4-S7 until the construction of the new pipeline 202, which includes the existing pipeline 201, is completed.

[0041] In step S2, the lifting adjustment component 3 is positioned 30-50cm away from the edge of the pipe trench 200 on the side adjacent to the pipe trench 200. The sliding adjustment fixing bolt 113 of the suspension frame body 11 of the suspension frame module 1 and the travel fixing bolt 123 of the travel component 12 are tightened. The suspension steel rope 2 directly suspends the existing pipe 201. After the two ends of the suspension steel rope 2 are tightened on the suspension frame body 11, they are fixedly connected by steel wire rope clips. In step S5, the telescopic support sleeve 42 of the telescopic support component 4 is rotated so that the arc-shaped support plate 44 of the telescopic support component 4 presses against the existing pipe 201. In step S6, the travel fixing bolt 123 of the travel component 12 is loosened, thereby pushing the suspension frame module 1 to move to the position corresponding to the next pipe trench 200. In step S8, after the construction of the new pipeline 202 containing the existing pipe 201 is completed, the existing pipe 201 can be protected or the components can be recycled for the next similar new pipeline.

[0042] In summary, by incorporating a lifting adjustment assembly 3 and a telescopic support assembly 4, this invention, when the existing pipeline 201 is deformed due to slack in the suspension steel cable 2 and ground compression settlement, drives the suspension frame module 1, along with the suspension steel cable 2, to rise, thereby lifting the existing pipeline 201 and controlling its deformation within a normal range, thus reducing the risk of pipeline damage. Simultaneously, the telescopic support assembly 4 detachably supports the existing pipeline 201, allowing the lifting adjustment assembly 3 to drive the suspension frame module 1, along with the suspension steel cable 2, to rise together, thus lifting the existing pipeline 201 and controlling its deformation within a normal range, reducing the risk of pipeline damage. Rope 2 descends together and releases the existing pipeline 201, thereby causing the suspension frame module 1 to move the suspension steel rope 2 to the next suspension position to suspend and protect the existing pipeline 201 at another position. By repeating this process, the suspension protection structure formed by the suspension frame module 1 and the suspension steel rope 2, together with the bottom support structure of the telescopic support component 4, can alternately protect the existing pipeline 201, realizing a production line-style protection of the existing pipeline 201. This can accelerate the construction of the new pipeline 202, greatly improve construction efficiency, and each structure can be reused.

[0043] The above-disclosed examples are merely preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. Therefore, any equivalent variations made in accordance with the claims of the present invention are within the scope of the present invention.
