Description

Technical Field

[0001] This utility model relates to the technical field of road support devices, specifically to a road support device for pipeline relocation. Background Technology

[0002] In the early stages of subway construction, the relocation of underground pipelines is often involved. This relocation process often requires the excavation of relevant roads or sites. To prevent disruptions, the relocation area is usually fenced off, affecting normal vehicle traffic. Moreover, pipeline relocation is typically carried out at night to avoid impacting residents' daily lives. When construction is stopped, the fencing is not removed until the entire construction is completed, at which point traffic can resume. Therefore, it is necessary to invent a road support device for underground pipeline relocation to ensure normal vehicle traffic during the day when construction is not underway. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a road support device for pipeline relocation, which can ensure that vehicles can pass normally on the road section when underground pipeline relocation is not under construction during the day.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows.

[0005] A road support device for pipeline relocation includes a square pit excavated downwards along both sides of the pipeline relocation trench. The length of the square pit is greater than the span of the pipeline relocation trench. A steel plate is laid in the square pit, and the upper surface of the steel plate is flush with the road surface. I-beam grooves are excavated downwards at the bottom of the square pit, perpendicular to the direction of the pipeline relocation trench and evenly distributed. The two ends of the I-beam grooves extend out from both sides of the pipeline relocation trench. I-beams are installed in the I-beam grooves to support the steel plate.

[0006] In the aforementioned road support device for pipeline relocation, the width of the square pit is 10mm longer than the width of the corresponding steel plate, and the width of the long side of the square pit is 10mm greater than the width of the long side of the corresponding steel plate.

[0007] The aforementioned road support device for pipeline relocation uses I32b I-beams, with a spacing of 500mm between adjacent I-beam trenches; the length of the I-beams located outside the edges of the pipeline relocation excavation trenches on both sides is not less than 500mm.

[0008] The aforementioned road support device for pipeline relocation includes a rubber pad on top of the I-beam for shock absorption, the rubber pad having a thickness of not less than 10mm.

[0009] The aforementioned road support device for pipeline relocation has an anti-slip paint layer on the upper surface of the steel plate, the thickness of which is not less than 1.5 mm.

[0010] The aforementioned road support device for pipeline relocation has a span of no more than 3m for the excavation trench used for pipeline relocation.

[0011] The aforementioned road support device for pipeline relocation has a span of more than 3m in the trench excavated for pipeline relocation.

[0012] The aforementioned road support device for pipeline relocation includes symmetrically distributed vertical supports installed below the I-beams, and a concrete pad with a thickness of 300mm is provided at the bottom of the pipeline relocation trench to facilitate the installation of the vertical supports.

[0013] The technological advancements achieved by this utility model are as follows, due to the adoption of the above technical solutions.

[0014] This utility model provides a road support device for pipeline relocation. By setting a supporting steel plate above the trench excavated for pipeline relocation and setting an I-beam below the steel plate for support, it is convenient for normal traffic during the day when no construction is needed. When construction is needed at night, the steel plate can be lifted for normal construction. Since the surface of the steel plate is flush with the road surface, the support device will not have a significant impact on vehicles during the day. The I-beam is embedded in the I-beam groove to restrict the I-beam, so that the I-beam can remain upright and stable without being welded to the upper steel plate, which facilitates the assembly of the support device.

[0015] This utility model also protects the support device by laying rubber pads on the surface of the I-beam and coating the surface of the steel plate with an anti-slip paint layer, which plays a certain role in shock absorption and anti-slip, greatly reducing the noise generated when vehicles pass over the support device and reducing the impact on non-motorized vehicles and pedestrians due to the smooth surface of the steel plate. Attached Figure Description

[0016] Figure 1 This is a schematic diagram of the specific structure of Embodiment 1 of the present utility model;

[0017] Figure 2 This is a schematic diagram of the specific structure of Embodiment 2 of this utility model.

[0018] The components include: 1. Road surface, 2. Pipeline relocation trench excavation, 3. Steel plate, 4. I-beam, 5. Rubber pad, 6. Vertical support, and 7. Concrete base layer. Detailed Implementation

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. Example

[0020] A road support device for pipeline relocation, such as Figure 1 As shown, the trench 2 for pipeline relocation is excavated downwards from the road surface 1 on both sides. The length of the trench is greater than the span of the trench 2 for pipeline relocation. A steel plate 3 is laid in the trench, and the upper surface of the steel plate 3 is flush with the surface of the road surface 1.

[0021] The upper surface of the steel plate 3 is provided with an anti-slip paint layer. At the bottom of the square pit, there are I-beam trenches that are perpendicular to the direction of the pipeline relocation excavation trench 2 and are evenly distributed. The two ends of the I-beam trenches extend out of the sides of the pipeline relocation excavation trench 2. I-beams 4 that support the steel plate 3 are installed in the I-beam trenches. Rubber pads 5 are laid on top of the I-beams 4.

[0022] The width of the square pit is 10mm longer than the width of the corresponding steel plate 3, and the length of the square pit is 10mm wider than the length of the corresponding steel plate 3, so that the steel plate 3 can be placed inside the square pit.

[0023] The spacing between adjacent H-beam trenches is 500mm. I32b H-beam 4 is used. The length of I-beam 4 located outside the two sides of the pipeline relocation excavation trench 2 is not less than 500mm.

[0024] The rubber pad 5 is at least 10mm thick, which can play a certain role in shock absorption and reduce the noise generated when the vehicle passes over the support device.

[0025] The thickness of the anti-slip paint layer is not less than 1.5mm. By applying anti-slip paint to the surface of the steel plate, it plays a good anti-slip role and can greatly reduce the impact of setting up support devices on non-motorized vehicles and pedestrians.

[0026] In this embodiment, the span of the pipeline relocation trench 2 does not exceed 3m.

[0027] During construction, the position of the embedded steel plate 3 is determined by laying out lines on the upper part of the trench 2 for pipeline relocation. Construction white lines are stretched on both sides of the steel plate 3 to ensure that the cutting machine cuts horizontally and vertically. After the cutting is completed, an electric pick is used to chisel the road surface downward to form a square pit to accommodate the steel plate 3. The depth of the chiseling is equal to the thickness of the embedded steel plate 3.

[0028] After the chiseling is completed, the I-beam trench is chiseled below the square pit in a direction perpendicular to the pipeline relocation excavation trench 2. The spacing between adjacent I-beam trenches is controlled at 500mm. After the chiseling is completed, I-beams 4 are laid in the I-beam trench, and then rubber pads 5 are laid on top of the I-beams 4 for shock absorption.

[0029] Finally, a crane is used to place the steel plate 3 coated with anti-slip paint into the square pit to complete the installation of the road support device. This allows vehicles to pass normally on the road during the day, and the support device can be partially lifted at night for pipeline relocation. Example

[0030] Based on Example 1, in this example, the span of the pipeline relocation trench 2 is greater than 3m. At this time, symmetrically distributed vertical supports 6 are installed below the I-beam 4, and a concrete cushion layer 7 is provided at the bottom of the pipeline relocation trench 2 to facilitate the installation of the vertical supports 6. The thickness of the concrete cushion layer 7 is 300mm.

[0031] This utility model provides a road support device for pipeline relocation. By setting a supporting steel plate above the trench excavated for pipeline relocation and setting an I-beam below the steel plate for support, it is convenient for normal traffic during the day when no construction is needed. When construction is needed at night, the steel plate can be lifted for normal construction. Since the surface of the steel plate is flush with the road surface, the support device will not have a significant impact on vehicles during the day. The I-beam is embedded in the I-beam groove to restrict the I-beam, so that the I-beam can remain upright and stable without being welded to the upper steel plate, which facilitates the assembly of the support device.

[0032] This utility model also protects the support device by laying rubber pads on the surface of the I-beam and coating the surface of the steel plate with an anti-slip paint layer, which plays a certain role in shock absorption and anti-slip, greatly reducing the noise generated when vehicles pass over the support device and reducing the impact on non-motorized vehicles and pedestrians due to the smooth surface of the steel plate.
