[0025] The embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. However, the present invention can be implemented in a variety of different ways as defined and covered below.

[0026] See also Figures 1 to 4The preferred embodiment of the utility model provides a scaffolding rock-attached platform for use on a high and steep slope, which is used to be erected on a high and steep slope. The high and steep slope includes an inclined rock layer and a supporting platform 4 located at the bottom of the inclined rock layer and arranged in a horizontal direction. The scaffolding rock-attached platform for the high and steep slope includes a slope rod 5, a rock-attached rod 6 and a cross rod 7. The slope rod 5 is used to be erected on one side of the inclined rock layer along the inclination of the inclined rock layer, the rock-attached rod 6 is fixed on the rock mass, and the cross rod 7 is used to be erected on one side of the inclined rock layer along the horizontal extension direction of the inclined rock layer. The cross rod 7, the slope rod 5 and the rock-attached rod 6 are connected to each other by fasteners; the scaffolding rock-attached platform for the high and steep slope also includes a rock-attached wall anchor rod 13 and a ground anchor rod 11 respectively fixedly connected to the cross rod, the rock-attached wall anchor rod 13 is used to be anchored on the inclined rock layer, and the ground anchor rod 11 is used to be anchored on the supporting platform 4. In this embodiment, after processing the loose and broken rocks on the slope rock wall, an inclined scaffolding is erected on the supporting platform 4. The slope rod 5 is adjusted according to the shape of the rock surface, and the control is encrypted at the place where the local change is large. The rock-attached rod 6 is attached to the rock mass for erection, and the rock-attached wall anchor rod is connected and fixed to the rock wall. The ground anchor rod 11 is implanted in the rock supporting platform 4. This structural setting makes the center of gravity of the scaffolding fall on the rock surface, the force is more uniform, the overall stability is good, the scaffolding is prevented from tilting outward and sliding and becoming unstable, and the load-bearing capacity of the frame is enhanced.

[0027] During the specific construction, first remove the isolated and dangerous rocks, rock masses with obvious cracks and high weathering degree on the slope according to the existing topography of the slope; after there is no loose and broken rock left on the slope, identify the stable form of the protruding rock surface. After treatment, the overall slope of the slope is between 45° and 70°, and the width of the horseway platform is 2.5m to 7m, so as to meet the requirements of pipe erection and safety protection. An inclined scaffolding is erected along the slope. The scaffolding can be divided into two forms according to the irregular shape of the rock mass. One of them is that when the rock mass has the conditions for slope cutting, a relatively regular slope can be formed, which is more convenient for the erection of the rock platform attached to the slope. See Figure 1 and Figure 2 The other is that the terrain is steep and it is difficult to cut the slope. It is necessary to use the existing terrain to intensify the construction to ensure the overall stability. Figure 3 Before formally setting up the scaffolding construction platform, the support platform 4 and the existing slope surface need to be cut and the gravel cleaned to ensure the stability of the connection components. The original slope landform line 1 is treated by blasting, mechanical slope cutting, etc. to form the existing slope forming surface 2; when it is an irregular rock surface, the operation method is as follows Figure 3 After the slope shaping is completed, there are holes in the local ground, which will affect the later platform construction. Fine stone concrete 3 is used to fill the local potholes and level the entire supporting platform 4.

[0028] In this embodiment, the slope rod 5 is used to be erected on one side of the inclined rock formation along the inclination of the inclined rock formation. Each rock-attached rod 6 is fixedly attached to the rock mass to form a stable connection. The crossbar 7 and the slope rod 5, the rock-attached rod 6, and the slope rod 5 and the rock-attached rod 6 are connected by fasteners, and the fasteners can be fasteners, wires, etc. The slope rods 5 are spaced 1.5m apart, the inner vertical rods are spaced 0.2m apart from the rock mass, the crossbar 7 is spaced 1.2m apart and not less than the width required by the drilling rig, and the horizontal step is set at 1.5m. The borehole diameter of the rock-attached wall anchor rod is 30mm, and the threaded steel bar anchor rod is driven into the rock stratum 30cm to facilitate the later implantation and consolidation of the steel bars; the borehole diameter of the anchor rod 11 is also 30mm, and the threaded steel bar anchor rod is driven into the support platform ground 40cm. The steel bar is made into a 180° bent anchor 18 fixed to the crossbar 7 and tightened by the wire 16. The rock-attached wall anchor rod 13 and the ground anchor rod 11 are reinforced by anchoring glue 12 .

[0029] In an embodiment of the utility model, a plurality of rock-attached wall anchor rods 13 are provided, and two adjacent rock-attached wall anchor rods 13 are arranged at intervals of a plurality of cross bars 7. A plurality of anchor rods 11 are provided, and two adjacent anchor rods 11 are arranged at intervals of a plurality of slope rods 5. Specifically, the rock-attached wall anchor rods 13 are arranged in a structural form in which two rock-attached wall anchor rods 13 are arranged for every three rows of cross bars 7, and the anchor rods 11 are arranged in a structural form in which one anchor rod 11 is arranged for every two rows of slope rods 5. During the erection of the rock-attached platform during scaffolding construction, the frame pipes on the rock-attached platform are fixed and tied by the rock-attached wall anchor rods 13 and the anchor rods 11 to prevent slippage. The rock-attached wall anchor rods 13 are made of Ф16 grade 3 steel bars to form a hook, which is fixed on the cross bar 7. The anchor rods 11 are arranged every two spans outside the frame, and a hole with a depth of 40 cm and a diameter of 30 mm is drilled in the rock mass. The anchor rod structure is consistent with the rock-attached wall anchor rod. During the reinforcement process, the rock-attached wall anchor rods 13 and the anchor rods 11 are implanted in the rock mass or the supporting platform 4 and then sealed and reinforced by the high-strength reinforcement glue 12. The anchor rods 11 need to be tied firmly with iron wires 16.

[0030] Optionally, the scaffolding further comprises transverse diagonal braces 8, which are diagonally arranged in a quadrilateral area formed by the cross bar 7 and the slope bar 5; two transverse diagonal braces 8 adjacent in the longitudinal direction are symmetrically arranged with the cross bar 7 as the axis, and two transverse diagonal braces 8 adjacent in the transverse direction are symmetrically arranged with the slope bar 5 as the axis.

[0031] Optionally, the scaffolding rock-attached platform for high and steep slopes further comprises an anchor steel pipe, wherein the anchor steel pipe is arranged at the top of the rock mass for connecting the scaffolding rock-attached platform. In this embodiment, the anchor steel pipe for connecting the scaffolding rock-attached platform is arranged at the top of the rock mass to prevent the frame pipe of the scaffolding rock-attached platform from sliding downward, thereby improving the installation stability of the scaffolding rock-attached platform.

[0032] In an embodiment of the utility model, the scaffolding rock-attached platform for high and steep slopes further comprises densification rods 10, which are used to be arranged at the slope change or corner of the inclined rock formation. The densification rods are arranged along the inclination of the inclined rock formation to strengthen the supporting force of the rock-attached platform. The slope rods 5 of the present application are erected on one side of the inclined rock formation along the inclination of the inclined rock formation. Because the rock mass is an irregular slope, the direction needs to be adjusted in time during the erection of the frame pipe, and the densification rods 10 are used for connection.

[0033] Optionally, the bottom of the slope rod 5 is stabilized by a triangular wooden wedge 9. Since the rock surface has a slope, the slope rod 5 has a certain angle with the ground, so the bottom is tightened and stabilized with a triangular wooden wedge 9 to prevent the downhill rod from sliding downward.

[0034] Optionally, the scaffolding rock-attached platform for the high and steep slope further includes a horizontal net 15, with the top of the scaffolding rock-attached platform as the starting position, and then a horizontal net 15 is set every several rows of cross bars 7. A safety net 14 is also set on the scaffolding rock-attached platform. To ensure construction safety, the utility model sets a dense mesh safety net on the outside of the scaffolding, sets a layer of horizontal net 15 on the top, and then sets a horizontal net 15 every 10m to prevent large rocks from falling from the upper platform or people from falling, thereby improving the safety of construction.

[0035] Optionally, a number of hole positions with reforestation holes 17 are reserved in the quadrilateral area formed by the crossbar and the slope bar. During the erection process, the positions of the holes 17 reserved for later reforestation need to be considered to avoid increasing the difficulty of drilling. After ensuring the safety of the platform, the width of the pipe rack is adjusted according to the hole-type hole positions so that the subsequent reforestation can be constructed normally. Drill holes at the designed point locations to connect the scaffolding rock rods 6 with the rock-attached wall anchor rods and the ground anchor rods 11; and timely test the pull-out force of the anchor rods, and regularly observe the settlement changes of the scaffolding. In order to ensure the stability of the scaffolding, a hydraulic anchor drill is set up on the scaffolding for drilling, and the base of the anchor drill is fixed on the crossbar 7 to drill holes into the reforestation holes 17 to ensure that the rack pipes are not shaken or tilted, and to ensure the construction effect and quality.

[0036] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
