Description

Technical Field

[0001] The invention relates to a slope protection project, in particular to a slope protection construction operation platform and a construction method thereof. Background Art

[0002] During the construction of slope protection projects, dedicated operating platforms are required to support key processes such as anchor bolting, shotcrete spraying, and lattice beam installation to ensure worker safety, improve construction efficiency, and guarantee project quality. Traditional construction methods often rely on scaffolding or simple hanging baskets, which present long installation cycles, poor stability, limited adaptability, and numerous safety hazards. This is particularly true in complex terrain, steep slopes, or high slopes, where conventional methods struggle to meet the dual requirements of safety and efficiency. As slope projects become steeper and more complex, the construction environment places higher demands on operating platforms. Existing technologies employ fixed platforms or sliding supports. While these improve operational stability to a certain extent, they often suffer from drawbacks such as difficult transfer, limited adjustment flexibility, and limited load-bearing capacity. Furthermore, most platforms lack an integrated design, preventing the coordinated operation of multiple processes, leading to repeated disassembly and assembly of equipment and impacting overall construction progress. Traditional construction methods rely on simple scaffolding, temporary fixed operating platforms, or large hoisting equipment for material transportation and transfer, or sliding supports. The main disadvantages of traditional construction methods are that they take a long time to build, have poor 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 cause injuries from falls from heights or falling rocks.

[0003] Therefore, there is an urgent need for a slope protection engineering construction operation platform with stable structure, strong adjustability, easy installation and safety protection function. It can adapt to different slope ratios, heights and geological conditions, integrate the working platform, safety protection and equipment support into one, and realize efficient, safe and modular on-site operations, thereby improving the overall construction level and operation safety of the slope protection project. Summary of the Invention

[0004] The present invention aims to overcome the shortcomings of the prior art by providing a slope protection construction operation platform and construction method thereof. The platform features a stable structure, strong adjustability, easy installation, and safety protection features. The platform can adapt to varying slope ratios, heights, and geological conditions, integrating a work platform, safety protection, and equipment support.

[0005] To achieve the above object, the present invention adopts the following technical solutions: A slope protection construction operation platform includes an inner and outer double row of diagonal bars parallel to the slope, wherein the inner and outer double rows of diagonal bars are respectively fixedly connected by multiple parallel longitudinal horizontal bars to form a grid-like frame, and multiple transverse horizontal bars are fixedly connected between the inner and outer grid-like frames to form a three-dimensional space frame, and the two side surfaces and two end surfaces of the three-dimensional space frame are connected by cross-arranged scissors braces; and the inner side surface of the three-dimensional space frame is provided with a tie point connected to the anchor rod driven into the slope.

[0006] The outer oblique rod is fixedly provided with longitudinal and transverse sweeping rods near the bottom end.

[0007] A small platform is carved out on the slope at the bottom of the diagonal pole, and wooden boards are placed on the platform.

[0008] A tie point is provided every two cloths and three spans on the inner side surface of the three-dimensional space frame.

[0009] Two layers of diagonal bars are erected every six spans along the slope, and the lower part of the frame serves as a diagonal brace, which is supported on the horizontal ground.

[0010] Anchor bolts are laid on the construction floor using panels made of non-slip steel or bamboo plywood. Non-slip steel, with its high strength and durability, is suitable for parking and operating heavy construction equipment. Bamboo plywood, with its light weight, low cost, and excellent non-slip properties, is suitable for pedestrians and the placement of small tools.

[0011] A working platform is set up at a certain distance on the outer row of the three-dimensional space frame, and a protective guardrail is set on the outside of the working platform to form a stepped scaffolding; 3 horizontal bars are set in the middle of each working platform and fixed on the vertical horizontal bar, and are set at equal intervals, with a spacing of no more than 75cm, and the working platform is fully covered with panels.

[0012] The width of each scissors brace is 4-6 spans, not less than 6m and not more than 9m; the inclination angle of the diagonal rod of the scissors brace to the horizontal plane is between 45-60°.

[0013] Stress sensing devices are arranged at the main nodes of the three-dimensional space frame.

[0014] A fall arrester is installed on the fixing point of the three-dimensional space frame.

[0015] The slope protection construction operation platform construction method includes the following steps: (1) The horizontal operation space is erected and the platform is installed from bottom to top; (2) For the construction of pedestrian ramps, the width of the passage shall not be less than 1 meter, the spacing between the diagonal and horizontal bars of the passage shall be adapted to the scaffolding, and guardrails shall be installed; (3) Safety protection and early warning part, including the installation of protective nets, pre-buried rod stress alarm devices at nodes and fall arresters.

[0016] The beneficial effects of the present invention are: (1) Strong adaptability. Traditional operating platforms, such as simple scaffolding, temporary fixed operating platforms, large hoisting equipment for material transportation and transfer, or sliding supports, cannot be adjusted according to technical standards such as design drawings. However, after the use of a slope protection construction operating platform, it can adapt to different slope ratios, heights and geological conditions as well as the requirements of design drawings and relevant specifications, reducing the impact of adverse factors and better meeting the high requirements of slope engineering towards steeper and more complex development.

[0017] (2) High work efficiency. Traditional operation platforms use simple scaffolding or temporary fixed operation platforms or large hoisting equipment for material transportation and transfer or sliding supports. When construction workers perform anchor drilling, grooving, steel bar binding, and concrete pouring, the operation space is narrow and the material transportation takes a long time, which is not conducive to the organization of flow construction operations. After the use of a slope protection construction operation platform, construction workers can make full use of the horizontal operation space and pedestrian ramp of the slope protection construction operation platform to transport materials and carry out process construction, which is convenient, fast and efficient.

[0018] (3) Good economic effect. Traditional operation platforms use simple scaffolding or temporary fixed operation platforms or large hoisting equipment for material transportation and delivery or sliding supports, etc., which need to be adjusted according to the construction progress. They lack integrated design and cannot achieve multi-process collaborative operation, resulting in repeated disassembly and assembly of equipment, causing waste of resources and increased costs. After the use of a slope protection construction operation platform, construction workers make full use of the horizontal operation space and pedestrian ramp of the slope protection construction operation platform to transport materials and carry out process construction, carry out various tasks, and set up the platform in one go, which greatly improves economic benefits.

[0019] (4) Good safety. Traditional operating platforms use simple scaffolding or temporary fixed operating platforms or large hoisting equipment for material transportation or sliding supports. The operating platform space is narrow and unstable, and there are no reliable protection measures, which can easily cause people to fall. After a slope protection construction operating platform is used, the outside of the operating platform is enclosed with a dense safety net, and stress monitoring points are arranged at the main rod nodes. For platform areas with high heights (over 10 meters) or greater operational risks, a fall arrester is installed. The fall arrester should be installed on a firm fixed point, and the operator is connected to the fall arrester through a safety belt. In the event of an accidental fall, the fall arrester can quickly brake to avoid serious injuries caused by the fall, thereby ensuring the safety of the personnel in the construction work.

[0023] like Figure 1-Figure 5 As shown, the slope protection construction operation platform includes an inner and outer double row of diagonal bars 4 parallel to the slope 8, and the inner and outer double row of diagonal bars 4 are respectively fixedly connected by multiple parallel longitudinal horizontal bars 7 to form a grid frame, and multiple transverse horizontal bars 9 are fixedly connected between the inner and outer grid frames to form a three-dimensional space frame, and the two side surfaces and two end surfaces of the three-dimensional space frame are connected by cross-arranged scissors struts 11; the width of each scissors strut is 4-6 spans, and is not less than 6m and not more than 9m; the inclination angle of the diagonal bar of the scissors strut to the horizontal plane is between 45-60°.

[0024] The inner side of the three-dimensional space frame is provided with a tie point connected to the anchor rod driven into the slope 8. The anchor rod is driven into the slope 8 through the anchor rod hole 5. An tie point is set every two spans on the inner side of the three-dimensional space frame.

[0025] External oblique rod 4 is fixedly provided with longitudinal sweeping rod and horizontal sweeping rod 3 near bottom. Small platform is chiseled out on the side slope of oblique rod 4 bottoms, and plank is cushioned on the platform.

[0026] Diagonal rods 4 are arranged in two layers, every six spans, following the slope. The lower portion of the frame serves as a diagonal brace, supported on the horizontal ground surface 1 and secured to the ground surface 1 via steel anchors 2. Anchor rods are used to lay panels 10 on the construction floor. Panels 10 are made of non-slip steel or bamboo plywood. Non-slip steel, with its high strength and durability, is suitable for parking and operating heavy construction equipment. Bamboo plywood, with its light weight, low cost, and excellent non-slip properties, is suitable for pedestrians and the storage of small tools.

[0027] The outer row of the three-dimensional space frame is equipped with a working platform at a certain distance according to the needs of on-site construction, and a protective guardrail is set on the outside of the working platform to form a stepped scaffolding; three horizontal bars 9 are set in the middle of each working platform and fixed on the longitudinal horizontal bar 4, and are arranged at equal intervals, with a spacing of no more than 75 cm, and the working platform is fully covered with panels 10.

[0028] This slope protection construction operation platform adopts staggered slope scaffolding according to the actual situation of the slope. The scaffolding is set up according to the slope, and the slope rate changes with the slope rate of the excavated slope to meet the designed slope rate. The maximum height does not exceed 12m. According to the position of the anchor rod, the longitudinal distance of the scaffolding diagonal rod 4 is 1.4m, the step distance is 1.0-1.5m, and the horizontal distance is 1.5-2m. There are double rows of inner and outer frames, and the spacing and horizontal distance can be adjusted according to the slope on site. At 100-300mm from the bottom end of the outer diagonal rod, longitudinal and transverse sweeping rods 3 are set, and they are firmly connected to the diagonal rod 4 to prevent sliding. Considering the construction needs, the horizontal rod is close to the bottom end of the slope, and no separate sweeping rod is set. The inner diagonal rod and the longitudinal horizontal rod 7 are used as sweeping rods, and they are firmly connected to the transverse rod to prevent sliding. A small platform is chiseled out at the bottom of the inclined rod on slope 8, and a 10cm×10cm×4cm wooden board is placed underneath to ensure the base of the inclined rod is solid and stable. The main load-bearing area for the axial force of the scaffolding and construction loads is selected on the drop platform or slope change platform at the bottom of the slope. For safety reasons, horizontal longitudinal steel pipes are appropriately installed on the outside. To prevent the scaffolding from tipping outward, tie points are installed. Before grouting the anchor rods, a φ48 steel pipe is driven 1 meter into the slope. The exposed part is fixed to the scaffolding with fasteners, and a tie point is set every two or three spans. The drilling rig operates from the bottom up. After the anchor rods are completed, the tie points are also tied from the bottom up. Considering the heavy load on the working layer, the small crossbars on the working layer of the operating platform are appropriately increased before the drilling rig is in place.

[0029] The slope protection construction operation platform is mainly divided into three parts: the horizontal operation space part, the pedestrian ramp part (the two parts are interconnected for personnel to go up and down), and the safety protection and warning part (protective net + pre-embedded rod stress alarm device at the node + fall arrester).

[0030] The first step is to set up the horizontal operating space (the platform is set up from bottom to top to install the diagonal rods (then the diagonal rods and sweeping rods are fastened with right-angle fasteners) → install the sweeping crossbars → install the first large crossbars → install the first small crossbars → calibrate the diagonal rods → set up the first row of anchor points → install the second large crossbars → the second small crossbars... and so on. Diagonal rods are set up in 2 layers every 6 spans along the slope, serving as diagonal braces at the bottom of the frame, and the diagonal braces are supported on the horizontal ground.

[0031] The construction floor is paved with panels 10 to facilitate the placement of anchor bolting equipment and construction. The panel materials used are non-slip steel or bamboo plywood. Non-slip steel, with its high strength and durability, is suitable for the parking and operation of heavy construction equipment. Bamboo plywood, with its light weight, low cost, and excellent non-slip properties, is suitable for pedestrians and the placement of small tools. Non-slip steel 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.

[0032] The anti-slip steel panels are welded or bolted to the scaffolding to ensure a tight fit and prevent loosening during use. The bamboo plywood is secured to the scaffolding using self-tapping screws or specialized fasteners. The spacing between the screws or fasteners should be kept within a reasonable 20-30 cm to ensure the smoothness and stability of the bamboo plywood.

[0033] Steel pipe scaffolding is set up in layers along the excavated slope. Each layer of scaffolding is based on the existing platform (step). The scaffolding is located 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 bars 4 of each layer of support is 4-6m long, and a 1.2m high protective guardrail is set on the outside of the working platform to form a stepped scaffolding; three horizontal bars 9 are set in the middle of each working platform and fixed on the longitudinal horizontal bar 7. They are set at equal intervals, with a spacing of no more than 75cm, and the platform is fully covered with panels 10.

[0034] A scissors brace 11 is set at both ends and in the middle of the frame at intervals of no more than 15m, and should be set continuously from bottom to top; the width of each scissors brace 11 is 4-6 spans, and is not less than 6m and not more than 9m; the inclination angle of the scissors brace diagonal rod to the horizontal plane is between 45-60°.

[0035] The second step is to erect the pedestrian ramp (the width of the passage is not less than 1 meter, the spacing between the diagonal and horizontal bars of the passage should be adapted to the scaffolding, the foundation should be treated according to the requirements of the scaffolding, the spacing between the small horizontal bars of the pedestrian ramp should not exceed 1.5 meters, and guardrails should be installed).

[0036] The third step involves the safety protection and early warning phase (protective netting + pre-embedded rod stress alarm devices at nodes + fall arresters). A densely meshed safety net should be installed throughout the entire facade. The safety net should comply with relevant national standards and possess excellent flame retardancy and impact resistance. The safety net should be securely fastened to the guardrails, free of loopholes and gaps, to prevent people and objects from falling from the platform edge. Stress variation devices should be installed at the main rod nodes (i.e., stress monitoring point 6) in the lateral operating space and on the pedestrian ramp. Fall arresters should be installed in areas of the platform that are higher (over 10 meters) or present greater operational risks. The fall arrester should be mounted on a secure fixed point, and the operator should be connected to the fall arrester via a safety belt. In the event of an accidental fall, the fall arrester will quickly brake the operator to prevent serious injury from the fall, ensuring construction safety.

[0037] Although the above describes the specific embodiments of the present invention in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art on the basis of the technical solution of the present invention without any creative work are still within the scope of protection of the present invention.
