Description

Technical Field

[0001] This utility model relates to the field of pipeline technology, and in particular to a pipeline support device for backfilling in gas engineering. Background Technology

[0002] With the improvement of living standards, the urban gas industry has developed rapidly, with a significant increase in consumption, number of users, and penetration rate. In particular, the widespread use of natural gas has spurred a leap forward in the urban gas industry. Gas pipelines are the core component of the gas transmission and distribution system.

[0003] With rapid urban expansion and increasing municipal engineering projects, direct pressure is exerted on pipelines during construction and other building processes, as well as by vehicles driving overhead and temporary storage of goods. This pressure keeps the pipelines under intense dynamic stress for extended periods, which can lead to fatigue, cracks, or fractures over time. This poses a significant threat to the safe operation of the pipelines. Existing protective facilities for buried gas pipelines suffer from simplistic design and insufficient protective effectiveness. Damage to these pipelines would result in substantial losses.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A pipeline support device for backfilling in a gas engineering project, buried in an underground trench, includes a pair of symmetrically arranged trapezoidal support bases, a detachable semi-circular arch pressure relief cover mounted on the two trapezoidal bases, two parallel fixed crossbars connected to and respectively embedded in the bottom of the two trapezoidal bases, a pipeline support seat detachably connected to the two fixed crossbars, and a gas pipeline fixed to the pipeline support seat by a steel wire rope.

[0007] The trapezoidal support base includes a trapezoidal body, a first limiting groove located on the top of the trapezoidal body near the semi-circular arch pressure relief cover, a connecting circular hole located at the bottom of the first limiting groove, and a second limiting groove located at the bottom that matches the fixed crossbar.

[0008] The semi-circular arch pressure relief cover includes a semi-circular arch body, snap-fit ​​protrusions at both ends of the semi-circular arch body that match the first limiting slot, and through circular slots on the snap-fit ​​protrusions; the snap-fit ​​protrusions and the first limiting slots are in limiting contact; the connecting circular holes and the through circular slots are bolted together.

[0009] The pipe support includes a double-web I-beam body and a semi-circular pipe support connected to the top of the double-web I-beam body; the two ends of the semi-circular pipe support are respectively provided with connecting ears; the steel wire rope passes through the connecting ears to fix the gas pipe to the pipe support.

[0010] The fixed crossbar is connected to the trapezoidal support base at the bottom of the trench; a pipe protection chamber is formed between the semi-circular arch pressure relief cover and the trapezoidal support base, and the protection chamber is filled with the first backfill soil; a second backfill soil is filled above the semi-circular arch pressure relief cover and the trapezoidal support base; the first backfill soil is fine-grained soil.

[0011] Preferably, the fixed crossbar is arranged perpendicular to the direction of the gas pipeline to maintain the stability of the overall structure.

[0012] Preferably, the two ends of the fixed crossbar are provided with upwardly protruding locking protrusions, and correspondingly, the bottom of the second limiting groove is provided with a locking groove that matches the locking protrusions; the locking protrusions and the locking grooves are locked together, making the overall structure more stable and reliable, reducing the disturbance to the gas pipeline caused by external factors such as displacement, and improving the service life of the gas pipeline.

[0013] Preferably, the trapezoidal support base, the semi-circular arch pressure relief cover, and the fixing crossbar all consist of a precast reinforced concrete main body. The split design facilitates prefabrication and rapid installation. The precast components can support each other after assembly, ensuring the stability of the structure.

[0014] Preferably, the surface of the pipe support is coated with a fusion-bonded epoxy powder coating, which gives the component good corrosion resistance in underground soil and a longer service life.

[0015] Compared with the prior art, the pipeline support device for backfilling in gas engineering proposed in this application has the following advantages:

[0016] This utility model features a semi-circular arch pressure relief cap that evenly distributes the pressure from above to the support points at both ends, reducing lateral forces on the structure and making the arch structure highly stable under vertical loads. The trapezoidal support base below transfers the load from the semi-circular arch pressure relief cap to the underlying soil layer. Furthermore, the trapezoidal structure effectively reduces the impact of lateral forces on the trapezoidal support base, making it more stable and reliable, thus protecting the indoor pipelines. The bottom fixing crossbars prevent overall structural displacement, improving overall stability, and also secure the pipeline support, reducing pipeline displacement and extending its service life. The use of prefabricated components ensures precise and reliable connections while improving construction efficiency. Attached Figure Description

[0023] The following detailed description illustrates the specific implementation method:

[0024] Example 1

[0025] like Figure 1-5 As shown in the figure, this embodiment demonstrates a pipeline support device for backfilling in a gas engineering project, which is buried in an underground trench. It includes a pair of symmetrically arranged trapezoidal support bases 1, a detachable semi-circular arch pressure relief cover 2 mounted on the two trapezoidal bases, two parallel fixed crossbars 3 connected to and respectively embedded in the bottom of the two trapezoidal bases, a pipeline support seat 4 detachably connected to the two fixed crossbars 3, and a gas pipeline 6 fixed to the pipeline support seat 4 by a steel wire rope 5.

[0026] In this embodiment, the trapezoidal support base 1 includes a trapezoidal body 11, a first limiting groove 12 located on the top of the trapezoidal body 11 near the semi-circular arch pressure relief cover 2, a connecting circular hole 13 located at the bottom of the first limiting groove 12, and a second limiting groove 14 located at the bottom that matches the fixing crossbar 3. Specifically, the trapezoidal support base 1 can transfer the load force transmitted from the semi-circular arch pressure relief cover 2 to the soil layer below. On the other hand, the trapezoidal structure can effectively reduce the impact of lateral forces on the trapezoidal support base 1, making it more stable and reliable, thereby protecting the indoor pipeline.

[0027] In this embodiment, the semi-circular arch pressure relief cover 2 includes a semi-circular arch body 21, snap-fit ​​protrusions 22 at both ends of the semi-circular arch body 21 that match the first limiting slot 12, and through circular slots 23 on the snap-fit ​​protrusions 22; the snap-fit ​​protrusions 22 are limited and abut against the first limiting slot 12; the connecting circular hole 13 and the through circular slot 23 are bolted together. Specifically, the semi-circular arch pressure relief cover 2 can evenly distribute the pressure from above to the support points at both ends, reducing the lateral force of the structure and making the arch structure very stable when bearing vertical loads.

[0028] In this embodiment, the pipe support 4 includes a double-web H-beam body 41 and a semi-circular pipe support 42 connected to the top of the double-web H-beam body 41. The two ends of the semi-circular pipe support 42 are respectively provided with connecting ears 43. The steel wire rope 5 passes through the connecting ears 43 to fix the gas pipe 6 to the pipe support 4, providing stable and reliable support for the gas pipe 6. The use of steel wire rope 5 in conjunction with the semi-circular pipe support 42 can meet the fixed connection of the gas pipe 6 within a certain specification range, with strong adaptability and stability.

[0029] In this embodiment, the fixed crossbar 3 is connected to the trapezoidal support base 1 at the bottom of the trench; a pipe protection chamber 7 is formed between the semi-circular arch pressure relief cover 2 and the trapezoidal support base 1, and the protection chamber is filled with first backfill soil 8; a second backfill soil 9 is filled above the semi-circular arch pressure relief cover 2 and the trapezoidal support base 1; the first backfill soil 8 is fine-grained soil; the second backfill soil 9 can be the original soil from the trench excavation. In actual operation, the compaction degree of the first backfill soil 8 inside the protection chamber can be less than that of the second backfill soil 9 outside the protection chamber.

[0030] During the specific installation, first fix the fixed crossbar 3 to the bottom of the trench, then connect the trapezoidal support base 1 and the pipe support base 4, fix the gas pipe 6, first backfill the protective chamber with fine soil, then bolt the semi-circular arch pressure relief cover 2 to the trapezoidal support base 1, and then cover and compact the top of the device with backfill soil.

Further explanation is provided in a further feasible implementation of this embodiment, such as... Figure 3 As shown, the fixed crossbar 3 and the gas pipeline 6 are arranged perpendicular to each other to maintain the stability of the overall structure.

[0033] To further explain, in these implementation methods, such as Figure 5As shown, the fixed crossbar 3 has upwardly protruding locking protrusions 31 at both ends. Correspondingly, the bottom of the second limiting groove 14 has a locking groove that matches the locking protrusions 31. The locking protrusions 31 and the locking groove are locked together, making the overall structure more stable and reliable, reducing the disturbance to the gas pipeline 6 caused by external factors such as displacement, and improving the service life of the gas pipeline 6.

[0036] To further explain, in some other possible embodiments of this example, the surface of the pipe support 4 is coated with a fusion-bonded epoxy powder coating, which gives the component good corrosion resistance in underground soil and a longer service life.
