Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, specifically to a pipeline in-situ protection and restoration device. Background Technology

[0002] In recent decades, with the rapid development of the national economy and infrastructure construction, China's bridge engineering has ushered in an unprecedented "golden age." Driven by the synergistic advancement of materials science, design theory, and construction technology, magnificent bridges spanning natural barriers have sprung up like mushrooms after rain. From extra-long-span suspension bridges and cable-stayed bridges crossing rivers, lakes, and seas to prestressed concrete continuous beam bridges that are ubiquitous on the national expressway network, the scale of bridge construction and the level of technology have achieved historic breakthroughs.

[0003] However, as time goes by, many of the bridges built and opened to traffic in the early days have gradually entered their "middle age" or even "old age." Under the combined effects of long-term heavy traffic loads, repeated natural environmental erosion (such as carbonization and chloride ion corrosion), and the aging of the materials themselves, these old bridges have inevitably developed a series of problems. These problems mainly manifest as structural performance degradation, such as concrete cracking and spalling, steel reinforcement corrosion, prestress loss, and damage to auxiliary components such as supports and expansion joints. Their load-bearing capacity and safety reserves are often insufficient to meet the current increasing demand for heavy-load, high-volume traffic, posing potential safety risks and a serious challenge to road network operational efficiency and public safety.

[0004] Faced with a large stock of aging bridges and urgent needs for safe operation and maintenance, scientific and effective renovation has become one of the core issues in the field of bridge engineering. Currently, during bridge renovation, the dense network of pipelines on both sides of the bridge severely restricts the design and construction organization of renovation plans. Furthermore, since pipelines are usually owned and managed by different entities, coordination is extremely difficult, becoming a major bottleneck in project progress. Although existing technologies offer methods to protect pipelines in situ to avoid cross-departmental coordination issues, these methods only involve simple fixation with support frames and straps, which is insufficient for protecting and limiting the pipelines, making them prone to displacement and damage. Utility Model Content

[0005] Therefore, it is necessary to provide an in-situ pipeline protection and restoration device to address the problems of insufficient protection and limiting of existing pipeline in-situ protection methods, which make pipelines prone to displacement and damage.

[0023] Please see Figures 1-4 One embodiment of the pipeline in-situ protection and restoration device includes a support frame 10, a temporary protection frame 20, a protection structure 30, and a restoration structure 40.

[0024] The support frame 10 is used to fix it to the ground or an existing structure. That is, the support frame 10 can be directly fixed to the ground. When the support frame 10 is not enough to be fixed to the ground, such as when it is on the water surface, or when there is a better fixing position, the support frame 10 can also be fixed to an existing structure, such as a column maintenance support or a bridge abutment.

[0025] In one embodiment, the support frame 10 includes uprights 11 and horizontal bars 12, wherein the uprights 11 and horizontal bars 12 are arranged longitudinally and laterally, the uprights 11 are vertically arranged, the horizontal bars 12 are horizontally arranged, and the uprights 11 and horizontal bars 12 intersect. The uprights 11 are fixed to the ground or an existing structure, and the horizontal bars 12 are used to connect multiple uprights 11 in series, with multiple sets of horizontal bars 12 arranged at intervals along the axial direction of the uprights 11.

[0026] Based on the above embodiments, the support frame 10 further includes a scissor brace 13, which is used to increase the strength of the support frame 10. Specifically, the scissor brace 13 includes two diagonal rods 131, which are inclined and intersect each other. The two diagonal rods 131 are inclined in opposite directions and symmetrical to each other. The two ends of the diagonal rods 131 are connected to the upright rod 11 and / or the horizontal rod 12.

[0027] In this embodiment, the two ends of the diagonal brace 131 are connected to the intersection of the upright 11 and the horizontal bar 12, that is, the two ends of the diagonal brace 131 are connected to the upright 11 and the horizontal bar 12. Furthermore, multiple sets of scissor braces 13 are provided, and the ends of the diagonal braces 131 of two adjacent scissor braces 13 are connected to the same intersection of the upright 11 and the horizontal bar 12.

[0028] In one embodiment, the support frame 10 is provided with scaffold boards 14, which are used to support construction equipment or construction personnel so that construction personnel or construction equipment can carry out construction on the scaffold boards 14 for in-situ protection of pipeline 1.

[0029] Please see Figure 3 The support frame 10 has a support bracket 15 at its top, which has a receiving groove 151. The support bracket 15 is used to support the temporary protective frame 20. In one embodiment, the support bracket 15 includes a vertical tube 152, a longitudinal horizontal bar 153, and a transverse horizontal bar 154. The vertical tube 152 is mounted on the support frame 10. Specifically, the vertical tube 152 is mounted on the horizontal bar 12. The vertical tube 152 can be welded to the horizontal bar 12. The vertical tube 152 can also be part of the upright 11 of the support frame 10, with the portion of the upright 11 extending beyond the support frame 10 constituting the vertical tube 152.

[0030] The longitudinal horizontal bar 153 and the transverse horizontal bar 154 intersect to form the bottom surface of the receiving groove 151. The riser 152 is connected to the longitudinal horizontal bar 153 and / or the transverse horizontal bar 154 to support the longitudinal horizontal bar 153 and the transverse horizontal bar 154. At the same time, the riser 152 extends beyond the longitudinal horizontal bar 153 and the transverse horizontal bar 154 to form the side of the receiving groove 151. In other words, the riser 152, the longitudinal horizontal bar 153, and the transverse horizontal bar 154 cooperate to form the receiving groove 151.

[0031] In one embodiment, the support bracket 15 further includes a diagonal bracing steel pipe 155, with the two ends of the diagonal bracing steel pipe 155 connected to the support frame 10 and the vertical pipe 152, respectively. The diagonal bracing steel pipe 155 can support the support bracket 15 and maintain the stability of the support bracket 15 when it is under load.

[0032] The temporary protective frame 20 is slightly smaller than the receiving groove 151. The temporary protective frame 20 is installed within the receiving groove 151 and is an elongated member. It has a cable tray 21 extending longitudinally along the bridge direction to accommodate the pipeline 1. In one embodiment, the temporary protective frame 20 includes a base plate 22 and side plates 23 on both sides of the base plate 22. The base plate 22 is made of steel, and the side plates 23 are made of angle steel, welded and fixed to the base plate 22.

[0033] The protective structure 30 includes a protective sleeve 31, through which the pipeline 1 passes, thus wrapping and protecting the pipeline 1. In one embodiment, the protective sleeve 31 is a rigid tube, capable of withstanding forces to prevent the protective sleeve 31 from collapsing and damaging the pipeline 1 inside. The protective sleeve 31 has a cutout 32 penetrating its side wall, through which the pipeline 1 can be inserted into the protective sleeve 31.

[0034] Based on the above embodiment, the cut 32 of the protective sleeve 31 divides the protective sleeve 31 into two halves. After the pipeline 1 is inserted into the lower half of the protective sleeve 31, the upper half of the protective sleeve 31 is fastened onto the lower half of the protective sleeve 31 and then secured by the binding member 33 to prevent the two halves of the protective sleeve 31 from separating.

[0035] In one embodiment, the protective sleeve 31 may be a PVC pipe, and the binding element 33 may be wire. It is understood that in other embodiments, the protective sleeve 31 and the binding element 33 may also be made of other materials, such as rubber for the protective sleeve 31 and rope for the binding element 33.

[0036] Restoration structure 40 is used to re-secure pipeline 1 to the bridge. For example... Figure 5 As shown, in one embodiment, the restoration structure 40 includes a permanent protective frame 41 and a sidewalk steel structure 42.

[0037] The permanent protective frame 41 is installed on the outward-facing steel beam 2 on the sidewalk. After the permanent protective frame 41 is installed, the pipeline 1 is moved from the temporary protective frame 20 to the permanent protective frame 41 by a distance of approximately 50cm, the same distance as when the pipeline 1 was moved to the temporary protective frame 20. This allows for splicing-free operation of the communication optical cable, minimizing the impact on the cable. Finally, the sidewalk steel structure 42 is installed on the permanent protective frame 41, covering it to prevent debris from entering the permanent protective frame 41 and damaging the pipeline 1.

[0038] The aforementioned pipeline in-situ protection and restoration device includes a temporary protective frame 20 installed within the receiving groove 151. The pipeline 1 is housed within the take-up groove 21 of the temporary protective frame 20. The take-up groove 21 limits the movement of the entire pipeline 1, preventing displacement or detachment that could damage it. Simultaneously, a protective sleeve 31 is fitted over the pipeline 1 to protect it from damage by equipment or debris during the process, ensuring its safety. After bridge construction is completed, the pipeline 1 is moved from the temporary protective frame 20 to the permanent protective frame 41. Finally, the permanent protective frame 41 is covered by a pedestrian walkway steel structure 42, achieving final protection for the pipeline 1.
