[0032] Construction scaffolding is a common temporary facility in construction. It is a framework erected for temporarily placing construction tools and building materials and facilitating high-altitude operations of construction workers. It is widely used in engineering fields such as road and bridge construction, water conservancy and hydropower projects, and building construction. Construction scaffolding faces significant safety risks during erection, use, and demolition processes. Especially for the construction cantilever platform scaffolding used in high-slope treatment projects, once problems occur, it is very likely to result in major work safety accidents with multiple fatalities and injuries.

[0033] In the construction activities of human society, continuous construction activities such as mining, excavation, and road construction are carried out. During the process, various geological problems need to be addressed. Among them, for high and steep slopes, due to their unique characteristics such as irregular slope terrain, long service time, high possibility of secondary disasters during use, and a large number of operating personnel, the construction of the cantilever platform scaffolding project for the high and steep slope protection project faces higher safety risks. Ensuring the construction safety of the cantilever platform scaffolding for the high and steep slope protection project is particularly important, urgent, and of great significance.

[0034] For ultra-high and steep rocky slopes, especially those with an inclination angle exceeding 55°, in the existing technology, it is impossible to erect a scaffolding on the ultra-high and steep rocky slope, resulting in extremely difficult or even impossible implementation of the protection construction on the ultra-high and steep rocky slope.

[0035] Refer to Figure 1 、 Figure 2 、 Figure 3 Accordingly, the present application provides a scaffolding structure for the construction of a high and steep slope protection project, including a cantilever platform 100, a first steel anchor pipe 200, and a framework 300.

[0036] The cantilever platform 100 is fixed on the slope 001. For a slope 001 with an inclination angle greater than 55°, the first steel anchor pipe 200 is obliquely fixed on the slope 001 so that the section of the first steel anchor pipe 200 extending out of the slope 001 inclines upward. For a slope 001 with an inclination angle less than 55°, the first steel anchor pipe 200 is vertically fixed on the slope 001. The vertical pole 301 of the framework 300 is supported on the cantilever platform 100, and the bottom of the vertical pole 301 of the framework 300 close to the slope 001 is connected to the first steel anchor pipe 200.

[0037] The overall structure of the framework 300 is supported by the cantilever platform 100. The vertical pole 301 of the framework 300 close to the slope 001 cannot be supported on the cantilever platform 100. Therefore, in the present application, the first steel anchor pipe 200 is installed on the slope 001, and the first steel anchor pipe 200 is connected to the bottom of the vertical pole 301 of the framework 300 to realize the connection between the framework 300 and the slope 001. This kind of scaffolding structure can be erected on the ultra-high and steep slope, and has better stability and safety, realizing the protection construction on the ultra-high and steep rocky slope.

[0038] Refer to Figure 1 For the first steel anchor pipe 200 on the steep vertical slope surface of the slope 001 with a slope ≥ 55°, a Φ48mm oblique steel anchor pipe is adopted. At each erection position of the vertical pole 301 of the slope 001, a φ55mm anchor pipe pre-buried hole is drilled in advance with a down-the-hole drill. After the first steel anchor pipe 200 is inserted, neat cement slurry (the water-cement ratio is controlled at 0.37 - 0.4:1) is injected into the hole for anchoring, and the effective rock-anchoring depth is not less than 2m.

[0039] The bottom of the first steel anchor pipe 200 and the vertical pole 301 is connected by fasteners, and the fasteners are of two types: cross fasteners and ring fasteners.

[0040] To ensure the stability of the vertical poles 301 of the framework 300, the connection part of the first steel anchor pipe 200 and the vertical pole 301 is as close as possible to the rock surface of the slope 001. At the same time, a cross bar 302 is added at a position 20 cm above the connection part of the vertical pole 301 and the first steel anchor pipe 200, and the added cross bar 302 and the vertical pole 301 are also connected by fasteners.

[0041] Refer to Figure 3 For a slope 001 with a gradient < 55°, the first steel anchor pipe 200 is a vertical anchor pipe with a diameter of φ28 mm vertically fixed on the slope 001. The rock-anchoring depth of the first steel anchor pipe 200 is not less than 2 m. The first steel anchor pipe 200 is anchored by a cement cartridge anchoring agent. The bottom of the vertical pole 301 of the framework 300 is inserted into the first steel anchor pipe 200, and the inserted length of the bottom of the vertical pole 301 is not less than 0.5 m. At the same time, it is ensured that the apron width (i.e., the horizontal distance between the bottom of the first steel anchor pipe 200 and the slope 001) is not less than 0.5 m. When the apron width does not meet the requirements, the first steel anchor pipe 200 should be lengthened.

[0042] Refer to Figure 2 To prevent the vertical poles 301 of the framework 300 from having vertical slip, in some embodiments, the construction scaffolding structure for the high-steep slope 001 protection project further includes steel anchor bolts 400. The steel anchor bolts 400 are fixed on the slope 001, and the section of the steel anchor bolts 400 extending out of the slope 001 is bent upward. The steel anchor bolts 400 are located below the first steel anchor pipe 200, and the bottom end of the vertical pole 301 of the framework 300 close to the slope 001 is sleeved on the bent section of the steel anchor bolts 400.

[0043] Specifically, steel anchor bolts 400 with a diameter of φ28 mm are added at the contact position between the bottom of the vertical pole 301 and the rock surface. The steel anchor bolts 400 are anchored to the slope 001 by a cement cartridge anchoring agent, and the effective anchoring depth is not less than 50 cm. The length of the steel anchor bolts 400 inserted into the vertical pole 301 is not less than 30 cm.

[0044] In some embodiments, the construction scaffolding structure for the high-steep slope 001 protection project further includes a second steel anchor pipe 500. The second steel anchor pipe 500 is obliquely fixed on the slope 001, and the section of the second steel anchor pipe 500 extending out of the slope 001 is inclined upward. The second steel anchor pipe 500 is connected to the vertical pole 301 of the nearest framework 300 through a connector 501. The connectivity between the framework 300 and the slope 001 is further improved.

[0045] Specifically, the second steel anchor pipe 500 is a Φ28mm anchor pipe anchored on the rock mass of the anchored slope 001. The second steel anchor pipe 500 is anchored to the mountain body using a cement cartridge anchoring agent, and the effective rock penetration depth is not less than 2m. The end of the second steel anchor pipe 500 extending out of the slope 001 is provided with an elbow with a length of 30cm, and the elbow angle is controlled at 45° to 60°. When installing the second steel anchor pipe 500, the elbow faces upward to facilitate the fixing of the connecting piece 501.

[0046] The connecting piece 501 includes a steel wire rope and a turnbuckle. The second steel anchor pipe 500 and the vertical pole 301 are connected by a steel wire rope and a turnbuckle. The connecting piece 501 is fixed by upward diagonal tension, and the diagonal tension angle is controlled at 45°, so that the frame body 300 and the second steel anchor pipe 500 are connected into a whole, playing a role in sectional unloading and preventing the scaffold from overturning outward under the action of the impact reaction force of the drill.

[0047] In this application, the depths of the first steel anchor pipe 200 and the second steel anchor pipe 500 anchored in the slope 001 are greater than 2 meters.

[0048] Refer to Figure 3 , in some embodiments, a bottom bar 600 close to the slope 001 is provided on the frame body 300, and the bottom bar 600 is connected to each first steel anchor pipe 200. Specifically, the bottom bar 600 is connected to each first steel anchor pipe 200 through a fastener, thereby further improving the stability of the frame body 300 on the slope 001.

[0049] To ensure that the safety reserve of the cantilever platform 100 meets the requirements, one end of the cantilever platform 100 far from the slope 001 is connected to the slope 001 through multiple stay cables 101.

[0050] Specifically, the stay cable 101 uses a φ20 stay steel wire rope to anchor the cantilever platform 100 to the slope 001. One end of the stay cable 101 is anchored in the slope 001 above the cantilever platform 100 by setting a ground anchor (anchored with a φ28 anchor rod + cement cartridge anchoring agent, and the rock anchoring depth is not less than 2m), and the other end is set at the end of the cantilever platform 100, and the angle is controlled at about 45°. The stay cable 101 plays a role in restricting the deformation of the end of the cantilever platform 100, thereby increasing the overall stability of the cantilever structure.

[0051] Refer to Figure 4 , Figure 5 , Figure 6 , in some embodiments, the cantilever platform 100 includes multiple cantilever brackets 110, and each cantilever bracket 110 is arranged side by side at intervals, and the cantilever brackets 110 are connected by longitudinal I-beams 120.

[0052] In some other embodiments, the cantilever support 110 includes a horizontal I-beam 111, a diagonal bracing I-beam 112, an I-beam hinge socket 113, and an I-beam reinforcing rod 114. The I-beam hinge socket 113 is provided with an I-beam slot 1131 and a rotating shaft seat 1132. The end of the diagonal bracing I-beam 112 is connected to the horizontal I-beam 111 through the I-beam hinge socket 113. The middle parts of both the horizontal I-beam 111 and the diagonal bracing I-beam 112 are sleeved with the I-beam hinge socket 113, and the rotating shaft seats 1132 between the two I-beam sockets are connected through the I-beam reinforcing rod 114.

[0053] Specifically, the cantilever platform 100 adopts a triangular bracket support form and is made of two I12 I-beams. One is horizontally arranged, namely the horizontal I-beam 111, and the other is obliquely arranged, namely the diagonal bracing I-beam 112. The inclination angle of the diagonal bracing I-beam 112 is 30°. The anchoring depth of the horizontal I-beam 111 in the slope 001 is 2 m, and the cantilever length is 4.5 m. The anchoring depth of the diagonal bracing I-beam 112 in the slope 001 is 1.5 m, and the cantilever length is 3.69 m.

[0054] The middle parts of both the horizontal I-beam 111 and the diagonal bracing I-beam 112 are sleeved with the I-beam hinge socket 113. The two ends of the I-beam reinforcing rod 114 are respectively connected to the rotating shaft seats 1132 of the two I-beam hinge sockets through rotating shafts, realizing the connection between the two I-beams. It should be noted that during the installation process, a part of the I-beam flange at both ends of the I-beam reinforcing rod 500 needs to be cut to prevent interference when the I-beam reinforcing rod 500 rotates.

[0055] In addition, the end of the diagonal bracing I-beam 112 is also connected to the horizontal I-beam 111 through the I-beam hinge socket 113. Specifically, the I-beam hinge socket 1 is sleeved on the horizontal I-beam 300, and the rotating shaft seat 200 on the I-beam hinge socket 1 is rotatably connected to the end of the diagonal bracing I-beam 400 through a rotating shaft. It should be noted that during the installation process, a part of the I-beam flange at the end of the diagonal bracing I-beam 400 needs to be cut to prevent interference when connecting to the rotating shaft seat 200.

[0056] The overall structure of the cantilever support 110 in this application is a detachable structure, eliminating the use of welded connection forms and facilitating subsequent disassembly, assembly, and recycling.

[0057] In the present application, the horizontal I-beam 111 includes a horizontal anchoring section and a horizontal cantilever section, and the diagonal bracing I-beam 112 includes a diagonal anchoring section and a diagonal cantilever section. The horizontal anchoring section is completely embedded inside the slope 001, and only its end is exposed on the slope 001. A first horizontal connecting plate is provided at the end of the horizontal anchoring section that is exposed on the slope 001, and a first horizontal connecting hole is opened on the first horizontal connecting plate. Similarly, the diagonal anchoring section is completely embedded inside the slope 001, and only its end is exposed on the slope 001. A first diagonal connecting plate is provided at the end of the diagonal anchoring section that is exposed on the slope 001, and a first diagonal connecting hole is opened on the diagonal connecting plate. The tail end of the horizontal cantilever section is provided with a corresponding second horizontal connecting plate, and a second horizontal connecting hole is opened on the second horizontal connecting plate. The tail end of the diagonal cantilever section is provided with a corresponding second diagonal connecting plate, and a second diagonal connecting hole is opened on the second diagonal connecting plate. When installing the cantilever support 110, the second horizontal connecting plate at the tail end of the horizontal cantilever section is connected to the first horizontal connecting plate by a connecting bolt, and the second diagonal connecting plate at the tail end of the diagonal cantilever section is connected to the first diagonal connecting plate by a connecting bolt, realizing the installation of the cantilever support 110 on the slope 001. This installation method uses a detachable connection method, which is convenient for subsequent disassembly and reuse.

[0058] Refer to Figure 5 、 Figure 6 In order to make the I-beam hinge bushing 113 firmly connected to the I-beam, in some embodiments, a limiting hole 1133 is provided on the I-beam hinge bushing 113. The limiting hole 1133 leads to the waist of the I-beam slot 1131, and a fastening member 1134 is used for connection in the limiting hole 1133.

[0059] Specifically, the limiting hole 1133 is horizontally opened in the middle of the I-beam hinge bushing 113 and communicates with the waist of the I-beam slot 1131. The inner wall of the limiting hole 1133 is provided with internal threads, and the fastening member 1134 is a fastening bolt. After the I-beam hinge bushing 113 is sleeved on the I-beam, the fastening member 1134 is rotated in the limiting hole 1133 to connect the I-beam and the I-beam hinge bushing 113.

[0060] In some embodiments, a plurality of support channel steels 115 are installed on the cantilever platform 100, and the bottom of the vertical pole 301 of the frame body 300 is supported in the support channel steels 115.

[0061] Specifically, the support channel steels 115 are arranged at intervals along the length direction of the horizontal I-beam 111. Each support channel steel 115 is connected to the horizontal I-beam 111 of each cantilever bracket 110. The 8# support channel steels 115 are arranged longitudinally on the upper part of the horizontal I-beam 111 of the cantilever platform 100. The openings of the support channel steels 115 face upward and are fixed to the horizontal I-beam 111 by U-shaped steel riding clips. The spacing of the support channel steels 115 is the same as the row spacing of the scaffolding vertical poles 301, ensuring that the scaffolding vertical poles 301 stand inside the channel steel and serve as the load-bearing members of the scaffolding while playing a role in anti-slip.
