Description

Technical Field

[0001] This application relates to the technical field of road widening, and in particular to pipeline protection devices applicable to road widening. Background Technology

[0002] Road widening is a comprehensive project involving traffic planning, engineering technology, environmental protection requirements, and cost management. If deficiencies are found during the compaction of the subbase, base course, and base course, small-scale road rollers and manual reinforcement are required. Blind spots can be reinforced with plain concrete. The connection between the old and new roads must be strictly treated, and a step milling process should be adopted. For example, in the reconstruction and expansion of the Liunan Expressway in Guangxi, the step excavation width is 120cm and the height is 80cm. Crushed stone is filled in layers and compacted to ensure the bonding strength between the old and new base courses. The junction of the old and new roadbeds should be moistened with water and brushed with micro-expansion cement slurry to prevent longitudinal cracking.

[0003] Road widening requires excavation of soil on both sides of the old road, making underground pipelines susceptible to construction disturbances: First, excavation loosens the soil around the pipelines, causing them to lose support and settle easily; second, improper operation of construction machinery can easily collide with the pipelines; and third, the load during the filling and compaction of the new roadbed can easily compress and deform the pipelines. Existing protection measures mostly consist of simple supports, with limited protection range and weak impact resistance, making it difficult to meet the safety requirements of pipelines. Therefore, it is necessary to propose a pipeline protection device suitable for road widening to solve the above problems. Utility Model Content

[0004] To address the problem that underground pipelines are susceptible to damage from settlement, collision, and compression during road widening in existing technologies, this application provides a protective device for pipelines in road widening projects.

[0005] The technical solution provided in this application for a pipeline protection device applicable to road widening is as follows: This is a pipeline protection device suitable for road widening, including an arc-shaped protective plate. Connecting ears are symmetrically installed on the left and right sides of the arc-shaped protective plate. A connecting plate is hinged to the bottom of the connecting ear. An adjusting leg is provided at the bottom of the connecting plate. A screw is installed in the internal thread of the adjusting leg. The top of the screw is rotatably connected to the connecting plate. A retaining wing plate is fixedly installed on the top of the connecting ear. The two connecting ears are connected by a transverse tie rod. Connecting components for connecting the connecting ears are symmetrically arranged on the front and rear sides of the transverse tie rod.

[0006] Through the cooperation of structures such as the arc-shaped protective plate and the adjustable outriggers, the inner side of the arc-shaped protective plate fits against the outer surface of the pipeline, thereby supporting the pipeline and preventing pipeline settlement during road widening. Furthermore, by setting up retaining wing plates on the top of the connecting ears, it can prevent loose soil excavated on both sides of the pipeline from sliding down and burying the pipeline and operating space, which facilitates subsequent pipeline connection, maintenance and backfilling operations. In addition, by setting up horizontal tie rods, each set of adjacent connecting ears can be connected to form an integral arched rigid frame, thereby solving the problem that underground pipelines are easily damaged by settlement, collision and squeezing during road widening.

[0007] A further improvement of the technical solution of this application is that: the connecting component includes a pair of locking blocks, the pair of locking blocks are fixedly connected to the front and rear sides of the connecting ear respectively, and the locking blocks are fitted into the interior of the transverse pull rod. The front and rear sides of the interior of the transverse pull rod are symmetrically provided with stop blocks, and the stop blocks are slidably connected to the inner wall of the transverse pull rod by springs. The bottom and inner side of the stop blocks are engaged with the locking blocks.

[0008] By adopting the above technical solution, the connecting components cooperate with each other. By inserting the locking block into the interior of the horizontal tie rod, the connecting ear can be connected to the horizontal tie rod, preventing the connecting ear from detaching from the horizontal tie rod in the horizontal direction. Furthermore, the spring force can squeeze the stop block, causing the stop block to lock into the inner side and bottom of the locking block, thereby preventing the connecting ear from detaching from the horizontal tie rod in the vertical direction. The horizontal tie rod can be disassembled at any time, which facilitates the individual transportation and storage of each set of connecting ears and arc-shaped protective plates, improving the flexibility of the device.

[0009] A further improvement of the technical solution of this application is that: a toggle block is fixedly installed at the bottom of the stop, and the bottom of the toggle block extends into the interior of the horizontal pull rod.

[0010] By adopting the above technical solution, the contact area between the operator's hand and the stop block can be increased by setting a toggle block, thereby facilitating the movement of the stop block.

[0011] A further improvement to the technical solution of this application is that: a second retaining strip is fixedly installed on the front side of the retaining wing plate, and a first retaining strip is fixedly connected to the rear side of the retaining wing plate.

[0012] By adopting the above technical solution, by setting clip 2 and clip 1, clip 1 and clip 2 of two adjacent sets of retaining wing plates can be interlocked, thereby improving the structural strength of the retaining wing plates, reducing the possibility of the retaining wing plates bending and deforming due to the impact of soil blocks, and thus improving the soil protection effect on the pipeline.

[0013] A further improvement to the technical solution of this application is that: reinforcing plates are fixedly installed on both the left and right sides of the retaining wing plate, and the inner side of the reinforcing plate is fixedly connected to the connecting ear.

[0014] By adopting the above technical solution, the connection between the connecting lug and the retaining wing plate can be thickened by installing a reinforcing plate, thereby further improving the structural strength of the retaining wing plate, reducing the possibility of the retaining wing plate bending and deforming due to the impact of soil, and thus improving the soil protection effect on the pipeline.

[0015] A further improvement to the technical solution of this application is that a buffer layer is attached to the bottom of the arc-shaped protective plate, and a number of raised ribs are provided on the lower surface of the buffer layer.

[0016] The above technical solution involves setting a buffer layer made of a material with elastic deformation properties. This allows the buffer layer to absorb and disperse impact energy through material deformation. Furthermore, by setting raised ribs, the buffer layer can generate guiding deformation when scraped, further dissipating the impact force and reducing the possibility of the pipeline being hit by a collision.

[0017] A further improvement to the technical solution of this application is that: connecting rings are fixedly installed on the left and right outer sides of the connecting ear, hooks are hung on the outer side of the connecting rings, steel wire ropes are fixedly installed on the outer side of the hooks, and ground anchors are fixedly connected to the outer side of the steel wire ropes.

[0018] The above technical solution, by setting ground anchors and steel wire ropes, can limit the lateral displacement of the pipeline after the ground anchors are driven into the soil on both sides of the pipeline, thus preventing the new roadbed filling from squeezing the pipeline.

[0019] In summary, this application includes at least the following beneficial technical effects: 1. This application provides a pipeline protection device suitable for road widening. By setting up arc-shaped protective plates and adjustable outriggers, it can support the pipeline and prevent pipeline settlement during road widening. It also uses retaining wing plates to prevent loose soil excavated on both sides of the pipeline from sliding down and burying the pipeline and operating space, which can facilitate subsequent pipeline connection, maintenance and backfilling operations. Furthermore, by setting up horizontal tie rods to connect each set of connecting lugs, it can form an integral arched rigid frame, thereby solving the problem that underground pipelines are easily damaged by settlement, collision and squeezing during road widening.

[0020] 2. This application provides a pipeline protection device suitable for road widening. By setting clip two and clip one, two adjacent sets of retaining wing plates are connected and clamped together, which can improve the structural strength of the retaining wing plates. Furthermore, by using a reinforcing plate to thicken the connection position between the connecting ear and the retaining wing plate, the structural strength of the retaining wing plate can be further improved, thereby reducing the possibility of the retaining wing plate bending and deforming due to the impact of soil blocks, and improving the soil protection effect on the pipeline.

[0021] 3. This application provides a pipeline protection device suitable for road widening. By setting up a buffer plate made of a material with elastic deformation properties, it can absorb and disperse the impact energy of the collision through the deformation of the material. At the same time, the raised ribs can generate guiding deformation when scraped, further dissipating the impact force, thereby reducing the possibility of the pipeline being hit by a collision.

[0022] 4. This application provides a pipeline protection device suitable for road widening. By setting ground anchors and steel wire ropes, after the ground anchors are driven into the soil on both sides of the pipeline, the lateral displacement of the pipeline can be restricted, and the pipeline can be prevented from being squeezed by the new roadbed filling.

[0025] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0026] Example 1 See Figure 1 , Figure 4 and Figure 5 This application provides a pipeline protection device suitable for road widening, including an arc-shaped protective plate 1. Connecting ears 2 are symmetrically installed on the left and right sides of the arc-shaped protective plate 1. A connecting plate 3 is hinged to the bottom of the connecting ears 2. An adjusting leg 4 is provided at the bottom of the connecting plate 3. A screw 5 is installed in the internal thread of the adjusting leg 4. The top of the screw 5 is rotatably connected to the connecting plate 3. A retaining wing plate 7 is fixedly installed on the top of the connecting ears 2. The two connecting ears 2 are connected by a transverse tie rod 16. Connecting components for connecting the connecting ears 2 are symmetrically arranged on the front and rear sides of the transverse tie rod 16.

[0027] In this embodiment, through the cooperation between structures such as the arc-shaped protective plate 1 and the adjustable support leg 4, the inner side of the arc-shaped protective plate 1 is in contact with the outer surface of the pipeline, thereby supporting the pipeline and preventing pipeline settlement during road widening. Furthermore, by setting a retaining wing plate 7 on the top of the connecting ear 2, it can prevent loose soil excavated on both sides of the pipeline from sliding down and burying the pipeline and operating space, which provides convenience for subsequent pipeline connection, maintenance and backfilling operations. Moreover, by setting a transverse tie rod 16, each adjacent set of connecting ears 2 can be connected to form an integral arched rigid frame, thereby solving the problem that underground pipelines are easily damaged by settlement, collision and squeezing during road widening.

[0028] Example 2 See Figure 3 , Figure 4 and Figure 5 Based on Embodiment 1, this application provides a technical solution: Preferably, the connecting component includes a pair of locking blocks 17, which are fixedly connected to the front and rear sides of the connecting ear 2 respectively, and the locking blocks 17 are fitted into the interior of the transverse tie rod 16. The front and rear sides of the interior of the transverse tie rod 16 are symmetrically provided with stop blocks 18, which are slidably connected to the inner wall of the transverse tie rod 16 by springs 19. The bottom and inner side of the stop blocks 18 are engaged with the locking blocks 17. A toggle block 20 is fixedly installed at the bottom of the stop block 18, and the bottom of the toggle block 20 extends out of the interior of the transverse tie rod 16. A second locking strip 10 is fixedly installed on the front side of the retaining wing plate 7, and a first locking strip 9 is fixedly connected to the rear side of the retaining wing plate 7. Reinforcing plates 8 are fixedly installed on both the left and right sides of the retaining wing plate 7, and the inner side of the reinforcing plate 8 is fixedly connected to the connecting ear 2.

[0029] In this embodiment, through the cooperation between the connecting components, the connecting ear 2 can be connected to the horizontal pull rod 16 by inserting the locking block 17 into the interior of the horizontal pull rod 16, preventing the connecting ear 2 from detaching from the horizontal pull rod 16 in the horizontal direction. Furthermore, the spring force of the spring 19 can press the stop block 18, causing the stop block 18 to engage with the inner side and bottom of the locking block 17, thereby preventing the connecting ear 2 from detaching from the horizontal pull rod 16 in the vertical direction. The horizontal pull rod 16 can be easily disassembled, facilitating the individual transportation and storage of each set of connecting ears 2 and the arc-shaped protective plate 1, thus improving the flexibility of the device. The addition of the toggle block 20 increases the operator's reach. The contact area between the part and the stop block 18 is increased, thus facilitating the movement of the stop block 18; by setting the second clamping strip 10 and the first clamping strip 9, the clamping strips 19 and the second clamping strip 10 of two adjacent sets of retaining wing plates 7 can be interlocked, thereby improving the structural strength of the retaining wing plate 7, reducing the possibility of the retaining wing plate 7 bending and deforming due to the impact of soil, and thus improving the soil protection effect for the pipeline; by installing the reinforcing plate 8, the connection position between the connecting ear 2 and the retaining wing plate 7 can be thickened, thereby further improving the structural strength of the retaining wing plate 7, reducing the possibility of the retaining wing plate 7 bending and deforming due to the impact of soil, and thus improving the soil protection effect for the pipeline.

[0030] Example 3 See Figure 1 and Figure 2 Based on Embodiment 2, this application provides the following technical solution: Preferably, a buffer layer 6 is attached to the bottom of the arc-shaped protective plate 1, and a plurality of raised ribs 15 are provided on the lower surface of the buffer layer 6; a connecting ring 11 is fixedly installed on the left and right outer sides of the connecting ear 2, a hook 12 is hung on the outer side of the connecting ring 11, a steel wire rope 13 is fixedly installed on the outer side of the hook 12, and a ground anchor 14 is fixedly connected to the outer side of the steel wire rope 13.

[0031] In this embodiment, by setting a buffer plate 6, which is made of a material with elastic deformation properties, the impact energy of the collision can be absorbed and dispersed through material deformation. Furthermore, by setting a raised rib 15, it can generate guiding deformation when scraped, further dissipating the impact force, thereby reducing the possibility of the pipeline being hit. By setting a ground anchor 14 and a steel wire rope 13, after the ground anchor 14 is driven into the soil on both sides of the pipeline, the lateral displacement of the pipeline can be restricted, avoiding the compression of the pipeline by the new roadbed filling.

[0032] The working principle of this pipeline protection device applicable to road widening is explained in detail below.

[0033] like Figures 1-5As shown, before construction, an arc-shaped protective plate 1 is installed along the pipeline route. The screw 5 is rotated to adjust the height of the connecting plate 3, and the bottom of the adjusting leg 4 is fixed to the soil to support the pipeline. Then, the two adjacent sets of clamp strips 10 and 9 are engaged with each other. The horizontal tie rod 16 is sleeved to the outside of the clamp block 17 from top to bottom. The clamp block 17 is then limited by the stop block 18. Finally, the ground anchor 14 is installed to fix the protective plate and wrap the elastic buffer layer to further protect the pipeline from collision.

[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
