Description

Technical Field

[0001] This utility model relates to the field of water conservancy pipeline technology, and in particular to a pressurized water conservancy pipeline. Background Technology

[0002] Water conservancy projects are engineering projects built to control and regulate surface water and groundwater in nature to achieve the purpose of eliminating harm and promoting benefits. They are also called water engineering projects. The foundation of water conservancy projects, namely water pipelines, is one of the most important components of water conservancy projects.

[0003] When laying drainage pipelines for water conservancy projects, water pipelines are often laid under some roads. However, in some rural roads, water pipelines are often buried directly in the soil beneath the road, and then the roadbed and cement road are laid directly on top of the soil layer above the water pipelines. This means that the water pipelines under rural roads have to directly bear the pressure from vehicles through the soil. Although rural roads are mostly used by small vehicles, the occasional passage of large, fully loaded trucks can exert excessive pressure, causing the road surface to crack and compress the water pipelines, resulting in damage and breakage. Therefore, it is necessary to improve the pressure-bearing capacity of the water pipelines used in water conservancy projects in the road area.

[0004] For example, in a water conservancy pipeline used in a water conservancy project (application number 202223519379.6), when a rural road is subjected to heavy pressure from a large, fully loaded truck, causing the road surface to crack and collapse, the pressure-bearing structure, supported by the soil layer outside the pipeline body, bears the pressure on behalf of the pipeline body, preventing the pipeline body from breaking under heavy pressure and affecting the drainage of the water conservancy project. However, in actual use, the rigid support achieved through the combination of sleeves, base plates, inclined plates, and pressure plates is easily misaligned in rural roads where the foundation material is relatively soft. After a heavy truck passes over, the positions of the support plates and foot plates at both ends are easily displaced, causing the sleeve to drive the water conservancy pipeline to shift, leading to pipeline connection breakage and affecting the drainage of the water conservancy project. The existing technology has room for improvement. Summary of the Invention

[0005] This utility model addresses the aforementioned existing situation by providing a pressurized water conservancy pipeline, comprising a laid pipeline, multiple pressure-bearing devices erected above the pipeline, and a base plate pressing against the multiple pressure-bearing devices. Each pressure-bearing device includes mounting columns fixedly installed on both sides of the pipeline and pressed into the road soil. A mounting seat is fixedly installed on the side of each mounting column facing the pipeline. A mounting frame is installed above the pipeline, with its two ends located above two mounting seats and baffles on both sides. The mounting frame has a cavity for accommodating the pipeline and is hollow. Several reinforcing plates are fixedly installed inside the mounting frame. A pressure plate is installed above the mounting frame, and the base plate is positioned above the pressure plate. A first guide post extending upwards and sequentially penetrating the mounting frame and pressure plate is fixedly installed on the mounting seat, with the upper end of the first guide post located within the base plate.

[0006] Preferably, the upper end of the mounting bracket is fixedly provided with a second guide post that extends upward and penetrates through the pressure plate, and a top block is fixedly provided on each side of the second guide post. A certain gap is left between the upper end of the top block and the pressure plate. A first spring that drives the pressure plate to move upward is sleeved on the first guide post. A stop block for limiting the pressure plate is fixedly provided on the mounting column. A first slot for engaging the stop block is opened at both ends of the pressure plate. A second slot for making way for the stop block and a third slot for engaging the first guide post and the second guide post are opened on the base plate.

[0007] Preferably, the first guide post has a mounting ring for mounting the first spring, and the first spring is located between the mounting ring and the pressure plate.

[0008] Preferably, the mounting frame has a first inclined surface on each side that gradually slopes downwards towards both sides of the mounting frame.

[0009] Preferably, the lower end of the pressure plate is fixedly provided with a plurality of pressure blocks extending downward to the upper part of the first inclined surface. A certain gap is left between the lower end of the pressure block and the first inclined surface, and the distance between the lower end of the pressure block and the first inclined surface is the same as the distance between the upper end of the top block of the pressure plate.

[0010] Preferably, four pressure blocks are provided and are respectively located above two first inclined surfaces, and a connecting plate is fixedly provided between two pressure blocks located above the same first inclined surface.

[0011] Preferably, there is a certain gap between the lower ends of both sides of the mounting bracket and the mounting base. A mounting groove is formed on the mounting base. The lower end of the first guide post is set in the mounting groove. A second spring that drives the mounting bracket to move upward is set in the mounting groove. A limiting block is fixedly set on the mounting base to press against the first inclined surface and limit the vertical movement distance of the mounting bracket.

[0012] Preferably, the lower end of the mounting base has a second inclined surface that gradually slopes downwards towards the mounting column.

[0013] Compared with the prior art, this utility model, when installing pipelines, buries the mounting column of the pressure-bearing device in the soil under the road, and uses the mounting frame to make way for the pipeline. By bearing pressure on the base plate, when a vehicle passes, the pressure is distributed to multiple sets of pressure-bearing devices by the entire base plate, and absorbed and dispersed by the mounting frame, replacing the pipeline in bearing the pressure. When the position of the mounting column is offset, the mounting frame will not affect the pipeline, effectively avoiding the situation where the pipeline is damaged due to excessive pressure.

[0019] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings:

[0020] like Figure 1-4As shown, a pressurized water conservancy pipeline includes a pipeline, multiple pressure-bearing devices 1 erected above the pipeline, and a base plate 2 pressed against the multiple pressure-bearing devices 1. The pressure-bearing device 1 includes mounting columns 3 fixedly installed on both sides of the pipeline and pressed into the road soil. A mounting seat 5 is fixedly installed on the side of the mounting column 3 facing the pipeline. The lower end of the mounting seat 5 has a second inclined surface 25 that gradually slopes downwards towards the mounting column 3. Usually, the pipeline is placed directly on the soil that has been initially compacted. During the installation of the mounting seat 5, the mounting seat 5 gradually moves downwards and pushes the soil below the mounting seat 5 to the bottom of the pipeline through the second inclined surface 25, further compacting the soil below the pipeline and making the soil below the pipeline more compact. A mounting bracket 6 is provided above the pipe. The two ends of the mounting bracket 6 are respectively located above two mounting seats 5, and baffles 4 are provided on both sides of the mounting bracket 6. A cavity 7 for accommodating the pipe is opened inside the mounting bracket 6, and the mounting bracket 6 is hollow. Several reinforcing plates 8 are fixedly installed inside the mounting bracket 6 to further improve the overall structural strength of the mounting bracket 6. A pressure plate 9 is provided above the mounting bracket 6, and the aforementioned base plate 2 is located above the pressure plate 9. A first guide post 10 is fixedly installed on the mounting seat 5, extending upward and passing through the mounting bracket 6 and the pressure plate 9 in sequence. The upper end of the first guide post 10 is located inside the aforementioned base plate 2. During pipeline installation, the mounting column 3 of the pressure-bearing device 1 is buried in the soil under the road, allowing the pipeline body to protrude from both ends of the soil under the rural road. Then, the pressure-bearing structure is buried, and the road is laid on top of the pressure-bearing structure. The mounting frame 6 makes way for the pipeline and bears pressure on the base plate 2. When a vehicle passes, the pressure is distributed to multiple sets of pressure-bearing devices 1 by the entire base plate 2, and absorbed and dispersed by the mounting frame 6, which takes the pressure from the pipeline. When the position of the mounting column 3 is offset, the mounting frame 6 will not affect the pipeline, effectively avoiding the situation where the pipeline is damaged due to excessive pressure. The mounting bracket 6 has a second guide post 11 fixedly installed at its upper end, extending upward and penetrating through the pressure plate 9. A top block 12 is fixedly installed on each side of the second guide post 11, with a certain gap between the upper end of the top block 12 and the pressure plate 9. A first spring 13, which drives the pressure plate 9 to move upward, is sleeved on the first guide post 10. A stop block 14, used to limit the movement of the pressure plate 9, is fixedly installed on the mounting post 3. First slots 15, used to engage the stop blocks 14, are respectively opened at both ends of the pressure plate 9. A second slot 16, used to allow the stop blocks 14 to move, and a third slot 17, used to engage the first guide post 10 and the second guide post 11, are opened on the base plate 2. A mounting ring 18, used to install the first spring 13, is opened on the first guide post 10, and the first spring 13 is located between the mounting ring 18 and the pressure plate 9. First inclined surfaces 19, gradually sloping downwards from top to bottom, are respectively opened on both sides of the mounting bracket 6.The lower end of the pressure plate 9 is fixedly provided with multiple pressure blocks 20 extending downward to the top of the first inclined surface 19. A certain gap is left between the lower end of each pressure block 20 and the first inclined surface 19, and the distance in the height direction between the lower end face of the pressure block 20 and the first inclined surface 19 is the same as the distance between the lower end face of the pressure plate 9 and the upper end face of the top block 12. Four pressure blocks 20 are provided, each located above two of the first inclined surfaces 19. A connecting plate 21 is fixedly provided between two pressure blocks 20 located above the same first inclined surface 19. When a heavy vehicle passes over the base plate 2, the greater gravity drives the base plate 2 and the pressure plate 9 downward, and the first spring 13 contracts until the pressure plate 9 abuts against the top block 12. Simultaneously, the pressure blocks 20 abut against the first inclined surfaces 19 on both sides of the mounting frame 6. The pressure is transmitted and dispersed downward through the mounting frame 6, achieving the first stage of buffering and effectively preventing direct pressure on the pipe from causing damage.

[0021] A certain gap is left between the lower ends of both sides of the mounting bracket 6 and the mounting base 5. A mounting groove 22 is formed on the mounting base 5. The lower end of the first guide post 10 is set in the mounting groove 22. A second spring 23 is set in the mounting groove 22 to drive the mounting bracket 6 to move upward. The second spring 23 surrounds the outer periphery of the first mounting post 3 and the upper end of the second spring 23 abuts against the lower end surface of the mounting bracket 6. A limiting block 24 is fixedly set on the mounting base 5 to press against the first inclined surface 19 and limit the vertical movement distance of the mounting bracket 6. As the pressure plate 9 moves downward, the pressure block 20 abuts against the mounting bracket 6. At this point, there is still considerable pressure. The pressure plate 9 and the mounting bracket 6 continue to move downward as a whole. The second spring 23 deforms and compresses to absorb the pressure until both ends of the mounting bracket 6 move downward and contact the mounting seat 5. The pressure is then transmitted through the mounting bracket 6 to the mounting seat 5 for dispersion, achieving the second stage of pressure buffering. At this time, the pipeline is still located in the cavity 7 of the mounting bracket 6, avoiding direct contact with the pipeline. After the pressure disappears, the pressure plate 9 and the mounting bracket 6 move upward and reset under the drive of the first spring 13 and the second spring 23, respectively. The pressure plate 9 and the mounting bracket 6 are limited by the stop block 14 and the limit block 24.

[0022] 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 to the specification derived therefrom are still within the protection scope of this utility model.
