[0020] Please see attached Fig.10 The embodiment of the present invention provides a safety protection structure under high slope conditions, including: a slope body 12, the slope body 12 is provided with a multi-step ramp, the slope body 12 ramps are all provided with a support interception frame 11, a plurality of foundations 5 are pre-buried at the top of the slope body 12, bolts 4 are pre-buried inside the plurality of foundations 5, pads 3 are provided between the tops of the bolts 4, concave steel plates 7 are fixedly connected between the tops of the plurality of pads 3, evenly distributed vertical steel pipes 2 are fixedly connected between the tops of the concave steel plates 7, lifelines 1 are fixedly connected between the plurality of vertical steel pipes 2, evenly distributed movable sliders 6 are slidably connected to the tops of the concave steel plates 7, an anti-fall device 8 is provided on the lifeline 1, and a drainage ditch is provided at the bottom of the slope body 12.

[0021] The support and interception frame 11 includes a wall connecting member 9 , which is fixedly connected to a slope body 12 , and an anti-falling net 10 is fixedly connected between the wall connecting member 9 and the slope body 12 .

[0022] The lifeline 1 is arranged above the vertical steel pipe 2, and the depth and width of the drainage ditch are 300*300.

[0023] See attached Figure 2 -Attached Figure 6 The vertical steel pipe 2, the pad 3, the movable slider 6, the concave steel plate 7, the wall connecting piece 9 and the supporting interception frame 11 are all made of Q235 material.

[0024] See attached Figure 8 , the vertical steel pipe 2 is φ48mm in size and 1m in length, inserted into the foundation 5 above the slope, the pad 3 is the same size as the foundation, 10mm thick, with a 48mm hole in the middle and four bolt holes around it. The vertical steel pipe 2 is mainly used to support and reinforce the slope protection structure and improve the overall stability of the slope. It is usually inserted into the foundation 5 above the slope and used in conjunction with the pad 3 and bolt 4 components to form a solid support system. The strength and stability of the vertical steel pipe 2 are crucial for slope protection and can effectively prevent slope landslides and collapse accidents.

[0025] See attached Figure 5 , the size of bolt 4 is φ18mm. Bolt 4 is used to connect vertical steel pipe 2, pad 3 and other components to ensure the stability and integrity of the entire protective structure. Prestress is generated by tightening to tightly connect the various components together. The tightness and connection quality of bolt 4 directly affect the stability and safety of the slope protection structure. The size of movable slider 6 is 100*100*100 in length, width and height, a is 220mm, b is 100mm, c is 10mm, d is 10mm; e is 20mm. The movable slider 6 is usually used in the adjustment and maintenance of slope protection structures. It can slide within a certain range to adapt to the deformation and displacement of the slope body. The use of movable slider 6 can increase the flexibility and adaptability of the slope protection structure and improve its stability under complex geological conditions.

[0026] The size of the wall connecting member 9 is φ48mm, the exposed length is more than 500mm, the embedded depth is selected according to the properties of the rock and soil, and the spacing is set as one step, three spans and one set. The embedded depth is selected according to the properties of the rock and soil, and the spacing is set as one step, three spans and one set. The wall connecting member 9 is mainly used to connect the slope protection structure with the surrounding buildings or structures to ensure the stability and integrity of the entire structure. The main purpose of the design is to withstand large loads and deformations. The use of the wall connecting member 9 can enhance the coordination between the slope protection structure and the surrounding environment, while improving its overall stability.

[0027] The size of the support and interception frame 11 is φ48mm, and the setting requirement is one step, three spans and one setting. Each step is equipped with a diagonal rod, the step distance is 1.5m, and the span is 1.5m. The top support and interception frame is mainly used to support and intercept earth and stone objects on the slope to prevent them from sliding or rolling down to the construction area or the road below to cause harm. The use of the support and interception frame 11 can effectively protect the safety of the construction area and the road below, and reduce the harm caused by the sliding or rolling down of earth and stone objects.

[0028] See attached Figure 2 With attached Figure 3The total length of the concave steel plate 7 is the same as the foundation spacing, a is 400mm, b is 30mm, c is 100mm, d is 10mm, e is 10mm, and f is 10mm. The concave steel plate 7 is usually used for the reinforcement and support of the slope protection structure. It has high strength and good toughness and can effectively resist the pressure and deformation of the slope body. The use of the concave steel plate 7 can enhance the overall stability and bearing capacity of the slope protection structure.

[0029] See attached Figure 1 -Attached Fig.10 A safety protection construction method under high slope conditions, the construction method comprising the following steps: Step 1: First, adjust the slope unit according to the slope height, determine a reasonable slope rate, and divide the high slope into several suitable units. The height of each slope is reasonably divided according to the properties of the rock and soil. Then, a platform is set up for each unit with a width of 2.5m. The width is adjusted to not less than 2.5m according to the on-site soil conditions. The purpose is to lay the foundation for the installation of the construction protection system 5. A drainage ditch needs to be set at the bottom of the slope body 12 for organized drainage of the slope body to avoid changes in the bottom structure of the slope body due to long-term immersion in water, loss of original stability, and sliding and collapse.

[0030] Step 2: Pre-embed the foundation 5 at the top of the slope and each platform in the middle to ensure that the position of the embedded parts is accurate and the depth meets the design requirements. When the foundation is embedded at the top, the distance from the slope edge should be less than 1m. Then embed bolts 4 in the foundation. Use soft materials to fill the embedded holes reserved for the vertical steel pipes 2. After the concrete is solidified, remove the fillers. The length of the foundation is set at one every 10m, which is determined based on the actual geological conditions on site.

[0031] Step 3: Fix the vertical steel pipe 2 on the embedded parts according to the design requirements, install the pad 3 at the bottom of the steel pipe, and use bolts 4 to connect the vertical steel pipe 2 and the pad 3 together to form a stable support structure to ensure the stability of the vertical steel pipe 2. Fix the concave steel plate 7 on the vertical steel pipe 2 according to the design requirements to ensure that the connection between the steel plate and the steel pipe is firm. Configure a movable slider 6 in the concave steel plate 7, test the mobility of the slider, and ensure that the slider can slide smoothly in the steel plate. Set a lifeline 1 above the vertical steel pipe 2. The lifeline should be firmly fixed on the steel pipe. Check the strength and stability of the lifeline to ensure that it can withstand the weight and impact of the construction workers. According to the construction needs and the requirements of the on-site environment, let the construction workers be equipped with anti-fall devices 8 to ensure that the connection between the anti-fall device and the lifeline is firm and reliable.

[0032] Step 4: First, build the support and interception frame 11: Build the support and interception frame 11 on the operating platform of each level of the slope to ensure the stability and load-bearing capacity of the frame. Use the wall connecting parts 9 to connect the frame with the vertical steel pipe 2 or the slope body 12. The wall connecting parts are set on the slope surface and are reasonably arranged according to the properties of the rock and soil. After the arrangement is completed, this position needs to be locally reinforced to ensure the strength of the tie. The wall connecting parts 9, the frame and the vertical steel pipe 2 form an integral structure that can more stably ensure the safety of the construction workers above. In addition, the anti-fall net 10 is laid under the support and interception frame 11, and the strength and integrity of the anti-fall net are checked to ensure that it can withstand impact and prevent objects from penetrating, and to ensure that the coverage of the net is large enough to effectively intercept objects that can fall. This can play a double insurance role in the safety of operations during and after the construction.

[0033] Step 5: After the top and slope surface of the slope are constructed, the lower frame needs to be removed, and the lifeline 1, vertical steel pipe 2, pad 3, bolt 4, movable slider 6, and concave steel plate 7 components at the top of the slope need to be moved to the next platform for installation, and at the same time, the wall connection 9, anti-fall net 10, and support interception frame 11 need to be set up on the platform below the next level of the slope. Then the above operation process is repeated in sequence until the construction of the final bottom slope is completed.

[0034] Through the combined use of various components, and in conjunction with the setting of the lifeline 1, the anti-fall device 8 and the anti-fall net 10, all-round safety protection is provided for construction workers in high slope operations. These devices can effectively prevent people from falling, reduce safety hazards during construction, and ensure the life safety of construction workers.

[0035] Through structural design and material selection, the entire protection system has high durability and corrosion resistance. This means that in the later maintenance process, the frequency of repair and replacement of the protection structure is reduced, thereby reducing maintenance costs. At the same time, the movable slider 6 design also facilitates regular inspection and adjustment of the protection structure to ensure its long-term stable operation.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
