Description

Technical Field

[0001] This invention relates to the field of shallow pipeline protection technology, and in particular to a road and bridge structure and its application method for protecting shallow buried pipelines in municipal road engineering. Background Technology

[0002] In municipal road construction, some pipelines are laid in shallow locations due to construction requirements. However, shallowly buried pipelines are subject to long-term vehicle pressure and are easily damaged, which reduces the effective service life of the lines or pipelines.

[0003] Traditional shallow-buried pipeline protection construction uses rigid pipes to protect the shallow-buried pipelines, which is ineffective and prone to displacement. At the same time, the existing protection structures are mostly hollow and simple in structure, with poor load-bearing capacity. They can still be damaged when run over by large vehicles, affecting the service life of the pipeline and failing to meet the usage requirements. Summary of the Invention

[0004] The purpose of this invention is to solve the above-mentioned problems by providing a road and bridge structure and its usage method for protecting shallow buried pipelines in municipal road engineering. This structure effectively avoids the phenomenon of shallow buried pipelines shifting or being exposed to the soil surface due to lateral pressure. At the same time, the arc-shaped inner top and triangular top give the device good load-bearing capacity, improve the protection effect and service life, and facilitate pipeline laying, thereby improving construction efficiency.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows: a road and bridge structure for protecting shallow buried pipelines in municipal road engineering, comprising a protection box mechanism and a support cover mechanism. The protection box mechanism includes a main box body, a central plate, a pipeline positioning mechanism, a pile, a positioning collar, and expansion bolts. The central plate is provided in the middle of the main box body, dividing the main box body into two spaces. The pipeline positioning mechanisms are symmetrically provided on both sides of the central plate. A pile is buried below the main box body, and a positioning collar is provided at the connection of the pile. The positioning collar is adapted to the top of the pile. The main box body and the top of the pile are fixed by expansion bolts.

[0006] Preferably, the support cover mechanism includes a positioning support mechanism, an arc-shaped inner top, a positioning mechanism, and a triangular top. The central plate is provided with an arc-shaped inner top through the positioning support mechanism, and triangular tops are provided on the upper sides of both sides of the main box.

[0007] Preferably, the pipeline positioning mechanism includes a bracing plate, an arc-shaped inner plate, a hinge seat, a rotating shaft, and a rotating cover. A 45° upward-inclined bracing plate is symmetrically provided at the junction of the central plate and the bottom of the main box. An arc-shaped inner plate is symmetrically provided above and below the bracing plate. The two ends of the arc-shaped inner plate are respectively fixed to the bracing plate, the central plate, and the main box. A hinge seat is symmetrically provided at the bottom of the central plate and the main box. A rotating cover is provided on the hinge seat through the rotating shaft. Multiple sets of hinge seats are provided at intervals. Two sets of rotating covers are provided and open in opposite directions. A pipeline is provided inside the arc-shaped inner plate.

[0008] Preferably, the positioning support mechanism includes a positioning insert plate, an adapter slot, and a positioning ramp. The positioning insert plate is provided above the neutral plate, and the adapter slot that mates with the positioning insert plate is provided below the arc-shaped inner top. Positioning ramps are symmetrically provided on both sides of the upper end of the neutral plate. The positioning ramps contact the inner side of the arc-shaped inner top. The end of the positioning ramp is provided with a groove, and a positioning block that mates with the groove is provided below the arc-shaped inner top.

[0009] Preferably, the positioning mechanism includes a positioning slot, an adapter plate, and a support plate. The positioning slots are symmetrically arranged on the upper sides of both sides of the main box, the adapter plates are symmetrically arranged on both sides below the triangular top, and the support plate is arranged in the middle of the lower part of the triangular top. The lower surface of the support plate is adapted to the upper surface of the arc-shaped inner top.

[0010] Preferably, the main box body outside the rotating cover is filled with soil and gravel, and a horizontal plate is provided below both ends of the arc-shaped inner top. The horizontal plate is buried in the filled soil and gravel. The inner side of the main box body is symmetrically provided with reinforcing ribs, and pipeline openings are provided at both ends of the main box body.

[0011] This invention also discloses a method for using a bridge structure to protect shallow buried pipelines in municipal road engineering, comprising the following steps: Step 1: Installation of the main housing.

The positioning collar at the bottom of the main housing is then fitted onto the piles, and the main housing is fixed to the piles using expansion bolts. Step 2: Opening the rotating cover. The pipeline to be buried is placed into the arc-shaped inner plate and passes through the pipeline opening to the pipeline openings on both sides of the next set of main housings to achieve pipeline arrangement. Then, the rotating cover is closed, and some soil and gravel are filled into the space of the main housing outside the rotating cover. Step 3: Installation of the triangular top.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the invention in a schematic manner, and therefore only show the components relevant to the invention.

[0019] Please refer to Figure 1-3A bridge structure for protecting shallow-buried pipelines in municipal road engineering includes a protective box mechanism and a support cover mechanism. The protective box mechanism includes a main box body 1, a central plate 2, a pipeline positioning mechanism, a pile 3, a positioning collar 4, and expansion bolts 5. The central plate 2 is located in the middle of the main box body 1, dividing the main box body 1 into left and right spaces. The pipeline positioning mechanisms are symmetrically arranged on both sides of the central plate 2. The pile 3 is buried below the main box body 1, and the positioning collar 4 is provided at the connection of the pile 3. The positioning collar 4 is adapted to the top of the pile 3. The main box body 1 and the top of the pile 3 are fixed by the expansion bolts 5. At this time, the main box body 1 and the pile 3 are fixed as one unit. Since the main box body 1 is set on the pile 3, it can effectively avoid the phenomenon of shallow-buried pipelines shifting or even exposing the soil surface due to lateral pressure, thus improving the overall stability.

[0020] In the present invention, the support cover mechanism includes a positioning support mechanism, an arc-shaped inner top 6, a positioning mechanism, and a triangular top 7. The central plate 2 is provided with an arc-shaped inner top 6 through the positioning support mechanism, and the upper sides of the main box 1 are provided with triangular tops 7. Through the upper triangular tops 7, the internal structure of the main box 1 can be protected, further improving the protection effect of the conduit.

[0021] The pipeline positioning mechanism includes a bracing plate 8, an arc-shaped inner plate 9, a hinge seat 10, a rotating shaft 11, and a rotating cover 12. A 45° upward-inclined bracing plate 8 is symmetrically positioned at the junction of the central plate 2 and the bottom of the main box 1. The bracing plate 8 is symmetrically positioned with arc-shaped inner plates 9 on its upper and lower sides. The two ends of the arc-shaped inner plate 9 are respectively fixed to the bracing plate 8, the central plate 2, and the main box 1. At this time, the arc-shaped inner plate 9, the bracing plate 8, the central plate 2, and the main box 1 form an arc-shaped sealed cavity, facilitating subsequent placement. The pipeline is placed in a sealed space without shaking or shifting. The bottom ends of the central plate 2 and the main box 1 are symmetrically provided with hinge seats 10. The hinge seats 10 are provided with rotating covers 12 via rotating shaft 11. The rotating covers 12 facilitate the opening and closing of the cavity and the placement and removal of the pipeline. Multiple sets of hinge seats 10 are arranged at intervals, and two sets of rotating covers 12 are provided and open in opposite directions. The pipeline is placed in the arc-shaped inner plate 9. After the rotating covers 12 are closed, the pipeline cannot shake in the arc-shaped inner plate 9.

[0022] Additionally, the positioning support mechanism includes a positioning insert plate 14, an adapter slot 15, and a positioning ramp 16. The positioning insert plate 14 is located above the neutral plate 2, and the adapter slot 15, which mates with the positioning insert plate 14, is located below the arc-shaped inner top 6. Positioning ramps 16 are symmetrically arranged on both sides of the upper end of the neutral plate 2. The positioning ramps 16 contact the inner side of the arc-shaped inner top 6. A groove is provided at the end of the positioning ramp 16, and a positioning block that mates with the groove is located below the arc-shaped inner top 6. This facilitates the installation of the positioning ramps 16. To improve installation accuracy, the positioning mechanism includes a positioning slot 17, an adapter plate 18, and a support plate 19. The positioning slots 17 are symmetrically arranged on the upper sides of both sides of the main box 1, and the adapter plates 18 are symmetrically arranged on both sides below the triangular top 7. The support plate 19 is arranged in the middle of the lower part of the triangular top 7. The lower surface of the support plate 19 is adapted to the upper surface of the arc-shaped inner top 6 to avoid the arc-shaped surface of the arc-shaped inner top 6 from shaking. At the same time, the arc-shaped inner top 6 and the triangular top give the device good load-bearing capacity.

[0023] In this invention, as a preferred embodiment, the main box 1 outside the rotating cover 12 is filled with soil and gravel. A horizontal plate 20 is provided below both ends of the arc-shaped inner top 6. The horizontal plate 20 is buried in the filled soil and gravel to prevent the positioning slot 17 from being loosely connected to the adapter plate 18. The inner side of the main box 1 is symmetrically provided with reinforcing ribs 21, and both ends of the main box 1 are provided with pipeline ports 22.

[0024] The present invention also discloses a method for using a bridge structure for protecting shallow buried pipelines in municipal road engineering, including the following steps: Step 1: Installation of the main box 1. Several sets of concrete piles 3 are driven along the pipeline 13 path. The depth of the concrete piles 3 is between 1.5 and 2.5 meters. Then, the positioning collar 4 below the main box 1 is put on the piles 3 and the main box 1 is fixed to the piles 3 by expansion bolts 5. The setting of the piles can effectively avoid the phenomenon of displacement of the shallow pipeline protection device under pressure after installation, making the device more firmly fixed. Step 2: Open the rotating cover 12, put the pipeline 13 to be buried on the arc-shaped inner plate 9 and pass it through the pipeline opening 22 to achieve pipeline arrangement with the pipeline openings on both sides of the next set of main boxes. Then close the rotating cover 12 and fill some soil and gravel into the space of the main box 1 outside the rotating cover 12. At the same time, some pipelines can also be pre-buried in the space of the main box 1 outside the rotating cover 12. When filling, the arc-shaped inner top 6 is positioned and installed above the central plate 2.

[0025] Before filling, cover the positioning slot with a thin film to prevent soil and gravel from falling into the positioning slot and affecting the installation of the triangular top. When filling with soil and gravel, compact the inside. Step 3: Installation of the triangular top 7. According to the adaptation relationship of the positioning mechanism, install the triangular top 7 on top of the main box 1. Then, according to the road construction paving layer, cover the main box 1 and the top of the triangular top 7 with the paving material.

[0026] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
