Description

Technical Field

[0001] This utility model relates to a slope protection project, and more particularly to a slope protection construction operation platform. Background Technology

[0002] In the construction of slope protection projects, to ensure the safety of workers, improve construction efficiency, and guarantee project quality, it is necessary to build dedicated operating platforms to support key processes such as anchor bolt installation, shotcrete application, and lattice beam installation. Traditional construction methods often rely on scaffolding or simple suspended platforms, which suffer from problems such as long installation cycles, poor stability, weak adaptability, and numerous safety hazards. Especially in complex terrain, steep slopes, or high elevations, conventional methods are insufficient to meet the dual requirements of safety and efficiency. As slope engineering becomes increasingly steep and complex, the construction environment places higher demands on operating platforms. In existing technologies, some projects use fixed platforms or sliding supports, which improve operational stability to some extent, but generally suffer from drawbacks such as inconvenient relocation, insufficient adjustment flexibility, and limited load-bearing capacity. In addition, most platforms lack integrated design, making it impossible to achieve multi-process collaborative operations, leading to repeated disassembly and assembly of equipment, affecting the overall construction progress. Traditional construction methods include erecting simple scaffolding, using temporary fixed operating platforms, employing large hoisting equipment for material transportation and transfer, or using sliding supports. The main drawbacks of traditional construction methods are that they are time-consuming, lack flexibility, and are difficult to adapt to complex slope terrain; fixed platforms cannot adjust height and angle, affecting construction efficiency; and insufficient safety protection measures can easily lead to falls from heights or rockfall injuries.

[0003] Therefore, there is an urgent need for a slope protection engineering construction operation platform that is structurally stable, highly adjustable, easy to install, and has safety protection functions. It should be able to adapt to different slope ratios, heights, and geological conditions, and integrate the operation platform, safety protection, and equipment load-bearing into one unit to achieve efficient, safe, and modular on-site operations, thereby improving the overall construction level and operational safety of slope protection engineering. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a slope protection construction operation platform. This platform has a stable structure, high adjustability, convenient installation, and safety protection functions. It can adapt to different slope ratios, heights, and geological conditions, integrating a work platform, safety protection, and equipment support into one unit.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A slope protection construction operation platform includes inner and outer double rows of diagonal braces parallel to the slope. The inner and outer double rows of diagonal braces are fixedly connected by multiple parallel longitudinal horizontal bars to form a grid-like frame. The inner and outer grid-like frames are fixedly connected by multiple transverse horizontal bars to form a three-dimensional spatial frame. The two sides and two ends of the three-dimensional spatial frame are connected by cross-set scissor braces. The inner side of the three-dimensional spatial frame is provided with tie points for connecting to anchor rods driven into the slope.

[0007] Longitudinal and transverse sweeping bars are fixedly installed near the bottom of the external diagonal brace.

[0008] A small platform was carved out on the slope at the bottom of the slanted rod, and wooden planks were placed on the platform.

[0009] A tie point is set on the inner side of the three-dimensional space frame every two spans.

[0010] Two layers of diagonal bracing are erected every six spans along the slope, with the lower part of the frame serving as diagonal bracing, which rests on the horizontal ground.

[0011] Anchor bolts are installed on panels on the working layer, with the panel material being either anti-slip steel plate or bamboo plywood. Anti-slip steel plate has the advantages of high strength and good durability, making it suitable for parking and operating heavy construction equipment; bamboo plywood, on the other hand, is lightweight, low-cost, and has good anti-slip properties, making it suitable for personnel walking and placing small tools.

[0012] A working platform is set at regular intervals on the outer side of the three-dimensional space frame. Protective railings are installed on the outside of the working platform to form a stepped scaffold. Three horizontal bars are set in the middle of each working platform and fixed to the vertical horizontal bars. They are set at equal intervals with a spacing of no more than 75cm. The working platform is fully covered with panels.

[0013] Each scissor brace has a width of 4-6 spans, and is no less than 6m and no more than 9m; the angle of inclination of the diagonal members of the scissor brace to the horizontal plane is between 45-60°.

[0014] Stress sensing devices are arranged at the main nodes of the three-dimensional space frame.

[0015] Fall arrestors are installed at the fixed points of the three-dimensional space frame.

[0016] The beneficial effects of this utility model are:

[0017] (1) High adaptability. Traditional operating platforms are constructed using simple scaffolding, temporary fixed operating platforms, or large hoisting equipment for material transportation and transfer, or sliding supports, etc., which cannot be adjusted according to design drawings and other technical standards. However, after the use of a new slope protection construction operating platform, it can adapt to different slope ratios, heights, geological conditions, and design drawing requirements and relevant specifications, reducing the impact of adverse factors and better meeting the high requirements of slope engineering as it develops towards steeper and more complex slopes.

[0018] (2) High work efficiency. Traditional operating platforms require simple scaffolding, temporary fixed operating platforms, or large hoisting equipment for material transportation and transfer, or sliding supports. When construction workers are drilling anchor bolts, trenching, tying reinforcing bars, or pouring concrete, the operating space is narrow, and material transportation is time-consuming, which is not conducive to organizing continuous construction operations. However, after using a slope protection construction operating platform, construction workers can make full use of the horizontal operating space and pedestrian ramp of the slope protection construction operating platform for material transportation and process construction, which is convenient, fast and efficient.

[0019] (3) Good economic benefits. Traditional operating platforms require simple scaffolding, temporary fixed operating platforms, or large hoisting equipment for material transportation and transfer, or sliding supports. These require adjustments to the position according to the construction progress, lack integrated design, and cannot achieve multi-process collaborative operation. This leads to repeated disassembly and assembly of equipment, resulting in resource waste and increased costs. However, after using a new slope protection construction operating platform, construction workers can make full use of the horizontal operating space and pedestrian ramp of the platform for material transportation and process construction, carrying out various tasks. The platform is erected in one go, greatly improving economic benefits.

[0020] (4) High safety. Traditional operating platforms often involve simple scaffolding, temporary fixed platforms, or the use of large hoisting equipment for material transport or sliding supports. These platforms are often cramped, unstable, and lack reliable safety measures, increasing the risk of falls. In contrast, this slope protection construction operating platform is enclosed by a dense safety net, with stress monitoring points placed at key joints. For platforms exceeding 10 meters in height or with significant operational risks, fall arrestors are installed. These fall arrestors are installed on secure fixed points, and workers are connected to them via safety belts. In the event of an accidental fall, the fall arrestor can quickly brake, preventing serious injury and ensuring worker safety. Attached Figure Description

[0029] like Figures 1-5 As shown, the slope protection construction operation platform includes inner and outer double-row diagonal braces 4 parallel to the slope 8. The inner and outer double-row diagonal braces 4 are fixedly connected by multiple parallel longitudinal horizontal bars 7 to form a grid-like frame. The inner and outer grid-like frames are fixedly connected by multiple transverse horizontal bars 9 to form a three-dimensional spatial frame. The two sides and two ends of the three-dimensional spatial frame are connected by cross-set scissor braces 11. The width of each scissor brace is 4-6 spans, and not less than 6m and not more than 9m. The angle of inclination of the diagonal brace to the horizontal plane is between 45-60°.

[0030] The inner surface of the three-dimensional spatial frame is provided with tie points that connect to the anchor rods driven into the slope 8. The anchor rods are driven in through anchor rod holes 5 on the slope 8. A tie point is provided every two spans (three sections) on the inner surface of the three-dimensional spatial frame.

[0031] A longitudinal sweeping bar and a transverse sweeping bar 3 are fixedly installed near the bottom of the external diagonal bar 4. A small platform is carved out on the slope at the bottom of the diagonal bar 4, and a wooden board is placed on the platform.

[0032] Two layers of diagonal bracing 4 are erected every six spans along the slope. The lower part of the frame serves as diagonal bracing, which rests on the horizontal ground 1 and is fixed to the ground 1 by steel anchors 2. Panels 10 are laid on the working layer above the anchors. The materials of panel 10 are anti-slip steel plates or bamboo plywood. Anti-slip steel plates have the advantages of high strength and good durability, and are suitable for parking and operating heavy construction equipment; bamboo plywood has the characteristics of light weight, low cost, and good anti-slip performance, and is suitable for personnel walking and placing small tools.

[0033] The outer edge of the three-dimensional space frame is equipped with a working platform at regular intervals according to the needs of on-site construction. The working platform is equipped with a protective railing to form a stepped scaffold. Three horizontal bars 9 are set in the middle of each working platform and fixed on the longitudinal horizontal bars 4. They are set at equal intervals with a spacing of no more than 75cm. The working platform is fully covered with panels 10.

[0034] This slope protection construction operation platform adopts staggered slope scaffolding based on the actual slope conditions. The scaffolding is set according to the slope gradient, and the slope ratio changes with the excavation slope ratio to meet the design slope ratio. The maximum height does not exceed 12m. According to the anchor bolt position, the longitudinal spacing of the scaffolding diagonal rods 4 is 1.4m, the step distance is 1.0-1.5m, and the transverse spacing is 1.5-2m. Double rows of scaffolding are set up, and the spacing and transverse spacing can be adjusted according to the site slope. 100-300mm from the bottom of the outer diagonal rod, longitudinal and transverse ground-level bracing rods 3 are set and firmly connected to the diagonal rods 4, with measures taken to prevent slippage. Considering the construction needs, no separate ground-level bracing rods are set for the horizontal rods near the bottom of the slope. Instead, the inner diagonal rods and longitudinal horizontal rods 7 are used as ground-level bracing rods and firmly connected to the horizontal rods, with measures taken to prevent slippage. At the bottom of the inclined rod on slope 8, a small platform is chiseled out of the slope, with 10cm×10cm×4cm wooden boards placed underneath to ensure the bottom of the inclined rod is solid and stable. The main load-bearing area for the axial force of the scaffolding and construction load is selected at the bottom of the slope's drop platform or slope-changing platform. For safety reasons, horizontal longitudinal steel pipes need to be appropriately installed on the outer side. To prevent the scaffolding from tilting outward, tie rods are installed. Before grouting the anchor rods, φ48 steel pipes are driven 1 meter into the slope, and the exposed part is fixed to the scaffolding with fasteners. A tie point is set every two rows and three spans. The drilling rig operates from bottom to top, and after the anchor rods are completed, the tie points are also tied from bottom to top. Considering the large load on the working layer, the small horizontal bars of the working layer of the operating platform are appropriately densified before the drilling rig is in place.

[0035] The slope protection construction operation platform is mainly divided into three parts: the horizontal operation space, the pedestrian ramp (the two parts are connected to each other for personnel to go up and down to work), and the safety protection and early warning part (protective net + stress alarm device for pre-embedded rods at nodes + fall arrestor).

[0036] The first step is to construct the horizontal operating space (the platform is constructed from bottom to top, installing diagonal braces (then the diagonal braces and ground braces are fastened together with right-angle couplers) → installing ground bracing → installing the first-step main horizontal bar → installing the first-step secondary horizontal bar → correcting the diagonal braces → setting the first row of tie points → installing the second-step main horizontal bar → the second-step secondary horizontal bar... and so on. Two layers of diagonal braces are constructed every six spans along the slope, serving as diagonal supports at the bottom of the frame, which rest on the horizontal ground.

[0037] A panel 10 is laid on the working layer to facilitate the placement of anchor bolt construction machinery and construction. The panel material is selected from either anti-slip steel plate or bamboo plywood. Anti-slip steel plate has the advantages of high strength and good durability, making it suitable for the parking and operation of heavy construction equipment; bamboo plywood is lightweight, low-cost, and has good anti-slip performance, making it suitable for personnel walking and the placement of small tools. Anti-slip steel plate is used for platform areas where heavy machinery such as large concrete spraying equipment frequently operates; bamboo plywood can be used for personnel passage and auxiliary work areas.

[0038] The anti-slip steel plate for the panel is fixed to the scaffolding by welding or bolting, ensuring a tight connection between the steel plate and the scaffolding to prevent loosening during use. The bamboo plywood is fixed to the scaffolding using self-tapping screws or special fasteners. The spacing between the screws or fasteners should not be too large, generally controlled between 20-30 cm, to ensure the flatness and stability of the bamboo plywood.

[0039] Steel pipe scaffolding is erected in layers along the excavated slope. Each layer of scaffolding is based on the existing platform (step). The scaffolding sits on each platform (step). The inner row is parallel to the slope 8, and the outer row has a working platform every 2-3 meters according to the needs of on-site construction. The outer row of diagonal braces 4 of each layer of support is 4-6m long. A 1.2m high protective railing is set on the outside of the working platform, forming a stepped scaffolding. Three horizontal bars 9 are set in the middle of each working platform and fixed on the longitudinal horizontal bars 7. They are set at equal intervals with a spacing of no more than 75cm. The platform is fully covered with panels 10.

[0040] A scissor brace 11 shall be installed at each end and in the middle of the frame every 15m, and shall be installed continuously from bottom to top; the width of each scissor brace 11 shall be 4-6 spans, and shall be no less than 6m and no more than 9m; the angle of inclination of the scissor brace diagonal bar to the horizontal plane shall be between 45-60°.

[0041] The second step is to construct the pedestrian ramp (the ramp width should be no less than 1 meter, the spacing of the diagonal and horizontal bars of the ramp should be compatible with the scaffolding, the foundation should be treated according to the scaffolding requirements, the spacing of the small horizontal bars of the pedestrian ramp should not exceed 1.5 meters, and guardrails should be installed).

[0042] The third step involves safety protection and early warning (protective netting + stress alarm devices embedded in the joints + fall arresters). A dense safety net is installed across the entire facade. The safety net should meet relevant national standards and have good flame retardancy and impact resistance. The safety net is securely tied to the guardrails, without any gaps or openings, to prevent personnel and objects from falling from the platform edge. Stress change devices are installed at key joints (i.e., stress monitoring point 6) of the relevant parts of the horizontal operating space and pedestrian ramps. For platform areas with higher heights (over 10 meters) or higher operational risks, fall arresters are installed. Fall arresters should be installed on secure fixed points, and workers are connected to them via safety belts. In the event of an accidental fall, the fall arrester should brake quickly to prevent serious injury. This ensures construction safety.

[0043] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
