Abstract
Description
Technical Field
[0001] This application relates to the field of slope treatment technology, and in particular to a combined protection structure for treating dangerous rock slopes. Background Technology
[0002] Nowadays, due to natural and human factors, some mountain slopes are prone to forming areas with low stability. These slopes can be categorized into soil slopes, unstable rock slopes, and others. Therefore, to ensure the safety of roads, rivers, and buildings around mountains, slope management is often implemented to reduce the potential threat posed by the slopes to structures below.
[0003] The traditional treatment method involves constructing multiple anti-slide piles on the slope. During construction, multiple rows of foundation pits are first dug on the slope, then steel cages are installed in the foundation pits, and finally concrete is poured to create anti-slide piles. These piles provide support to the rock mass on the slope, improve the stability of the slope, and reduce the possibility of collapse.
[0004] However, with the increase in usage time and the long-term erosion of the slope surface by rainwater, loose gravel is prone to appear on the slope surface, which may lead to gravel rolling down, thus still posing a significant threat to the buildings below the slope, and the treatment effect of dangerous rock slopes still needs to be improved. Summary of the Invention
[0005] In order to improve the treatment effect of dangerous rock slopes and reduce the threat to buildings below, this application provides a combined protection structure for dangerous rock slope treatment.
[0006] The combined protection structure for dangerous rock slope treatment provided in this application adopts the following technical solution:
[0007] A combined protection structure for treating dangerous rock slopes includes multiple anti-slide piles anchored to the slope and a passive protection net. The anti-slide piles include a steel cage and a concrete layer. The passive protection net includes multiple columns and multiple protective net panels. The multiple columns are all anchored to the lower edge of the slope and distributed along the length of the lower edge of the slope. The protective net panels are connected to at least two columns.
[0008] By adopting the above technical solutions, when in use, the anti-slide piles provide support to the rock mass at the slope, improving the stability of the slope and reducing the possibility of collapse. At the same time, the passive protection net provides further protection for the slope. If gravel rolls off the slope surface, the passive protection net can block the gravel, thereby reducing the threat to the buildings below and improving the treatment effect of dangerous rock slopes.
[0009] Optionally, the anti-slide pile is equipped with a traction column and a traction cable. The traction column penetrates the anti-slide pile and is simultaneously anchored to the slope. One end of the traction cable is connected to the traction column, and the other end is connected to the column.
[0010] By adopting the above technical solutions, the traction column reinforces the anti-slide piles, improving their stability during use. Furthermore, the traction column can also pull the passive protection net as a whole via traction cables, increasing its load-bearing capacity and reducing the likelihood of it tilting towards the building, further minimizing the threat to the building below and improving the treatment effect on dangerous rock slopes. Simultaneously, the anti-slide piles reinforce the traction column, ensuring its traction effect on the passive protection net.
[0011] Optionally, the traction column has multiple reinforcement holes for filling the concrete layer.
[0012] By adopting the above technical solution, during the concrete layer pouring process, some concrete will fill the reinforcement hole, thereby increasing the interlocking force between the traction column and the anti-slide pile, increasing the overall integrity of the two, so that the anti-slide pile has a better stabilizing effect on the traction column, and the traction column has a better traction effect on the passive protection net.
[0013] Optionally, a drainage pipe is pre-embedded in the anti-slide pile. The drainage pipe extends along the slope direction and penetrates the anti-slide pile. The drainage pipe is connected to the reinforcing cage and passes through the traction column, and is used to position the traction column when pouring the concrete layer.
[0014] By adopting the above technical solution, the drainage pipe facilitates the downward flow of water above the anti-slide pile, thus achieving a better drainage effect and preventing water from accumulating above the anti-slide pile. During the installation of the drainage pipe and the traction column, the drainage pipe has a positioning function for the traction column, reducing the possibility of the traction column swinging and making it less likely for the traction column to tip over when the concrete layer is poured later.
[0015] Optionally, the traction column is fixed with a connecting block, the connecting block has a slot, and the drain pipe sidewall is fixed with a connecting shaft, which is engaged and rotatably connected in the slot.
[0016] By adopting the above technical solution, when installing the drainage pipe, the drainage pipe is passed through the traction column and the connecting shaft is engaged in the slot. Thus, while the drainage pipe supports the traction column, it can also be rotated to adjust the tilt angle of the drainage pipe, thereby facilitating the installation of the drainage pipe at a suitable angle for drainage.
[0017] Optionally, the edge of the slot is formed with a limiting part, and the connecting shaft is sleeved and threaded with a clamping ring. The end face of the clamping ring is provided with a connecting ring groove that is coaxial with itself, and the connecting ring groove is used to engage with the limiting part.
[0018] By adopting the above technical solution, after the drain pipe is inserted into the traction column and the connecting shaft is engaged in the slot, the clamping ring is rotated and can slide towards the connecting block. Then, the limiting part is engaged in the groove of the connecting ring, thereby vertically positioning the drain pipe and the traction column, reducing the possibility of the drain pipe shaking up and down, and improving the stability of the drain pipe installation.
[0019] Optionally, a positioning block is formed on the side of the limiting part facing the connecting shaft, and a plurality of positioning grooves are provided on the peripheral wall of the connecting shaft for engaging with the positioning block, and the plurality of positioning grooves are distributed along the circumference of the connecting shaft.
[0020] By adopting the above technical solution, the tilt angle of the drainage pipe can be adjusted in advance during installation. After adjustment, the connecting shaft is engaged in the slot, so that the positioning block can be engaged in one of the positioning slots. This has the effect of rotational limiting on the installation of the connecting shaft and the drainage pipe, improving the stability of the drainage pipe installation and making it more convenient to tie the drainage pipe to the steel cage later.
[0021] Optionally, the top of the traction post is provided with an insertion hole, and a wedge-shaped plug is inserted into the end of the insertion hole away from the passive protection net. The small end of the wedge-shaped plug is inserted into the insertion hole, and the end of the traction cable facing the traction post passes through the wedge-shaped plug. The end of the traction cable passing through the wedge-shaped plug is divided into several cable joints, and the cable joints are wrapped around the wedge-shaped plug and clamped between the wedge-shaped plug and the inner wall of the insertion hole.
[0022] By adopting the above technical solution, in actual use, if the tension on the traction cable increases, the tension of the traction cable on the wedge-shaped plug will increase, thereby increasing the clamping effect of the wedge-shaped plug on the cable joint, making the connection between the traction cable and the traction post better and improving the use effect.
[0023] Optionally, the traction cable is equipped with a clip, which clamps the traction cable and abuts against the side of the traction post facing the passive protection net. The cable connector extends from the insertion hole to the side of the traction post facing the passive protection net and is simultaneously clamped by the clip.
[0024] By adopting the above technical solution, the clamp can not only hold the cable connector and the traction cable, but also limit the wedge-shaped plug, reducing the possibility of the wedge-shaped plug sliding away from the plug hole, thereby reducing the possibility of the wedge-shaped plug sliding back and forth and reducing the possibility of wear on the cable connector.
[0025] Optionally, the traction column is threaded with a push bolt, which abuts against the clamp.
[0026] By adopting the above technical solution, after the clamp is installed, the push bolt is installed on the traction column and the push bolt abuts against the clamp, thereby further increasing the limiting effect on the wedge-shaped insert and improving the stability of the wedge-shaped insert during use.
[0027] In summary, this application includes at least one of the following beneficial technical effects:
[0028] 1. When in use, the anti-slide piles provide support to the rock mass at the slope, improving the stability of the slope and reducing the possibility of collapse; if gravel rolls off the slope surface, the passive protection net can block the gravel, thereby reducing the threat to the buildings below and improving the treatment effect of dangerous rock slopes.
[0029] 2. The traction column has a reinforcing effect on the use of anti-slide piles, improving the stability of the anti-slide piles during use; it can also be used to pull the passive protection net as a whole through the traction cable, improving the passive protection net's load-bearing capacity, reducing the possibility of the passive protection net tilting towards the building, and further reducing the threat to the buildings below;
[0030] 3. The drainage pipes facilitate the downward flow of water above the anti-slide piles, resulting in better drainage and preventing water from accumulating above the piles. The drainage pipes also help to position the traction columns, reducing the possibility of them swaying and preventing them from tipping over during concrete pouring. Attached Figure Description

[0037] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.
[0038] This application discloses a combined protection structure for the treatment of dangerous rock slopes. (Refer to...) Figure 1 and Figure 2 The combined protection structure for dangerous rock slope treatment includes multiple anti-slide piles 1 and passive protection netting 2. The anti-slide piles 1 are anchored to the slope 3, and are arranged in rows. Each anti-slide pile 1 includes a steel cage 11 installed in the foundation pit and a concrete layer 12 poured into the pit. The passive protection netting 2 includes multiple posts 21 and multiple protective netting panels 22. The posts 21 are anchored to the lower edge of the slope 3, and are distributed along the length of the lower edge of the slope 3. The protective netting panels 22 are positioned between two adjacent posts 21 and are simultaneously fixed to both adjacent posts 21. Alternatively, the protective netting panels 22 can be fixed to any two or more posts 21.
[0039] When in use, the anti-slide piles 1 provide support to the rock mass at slope 3, improving the stability of slope 3 and reducing the possibility of collapse. At the same time, the passive protection net 2 provides further protection to slope 3. If gravel rolls off the surface of slope 3, the passive protection net 2 can block the gravel, thereby reducing the threat to the buildings below and improving the treatment effect of dangerous rock slope.
[0040] Reference Figure 1 In addition, the anti-slide pile 1 is equipped with a traction column 4 and a traction cable 5. The traction column 4 penetrates the anti-slide pile 1 vertically and is anchored to the slope 3 from the bottom of the anti-slide pile 1. The traction column 4 has multiple reinforcement holes 41. One end of the traction cable 5 is connected to the top of the traction column 4, and the other end is connected to the column 21.
[0041] During construction, the traction column 4 is first anchored to the bottom of the foundation pit. Then, a reinforcing cage 11 is installed inside the pit, followed by the pouring of a concrete layer 12 to form the anti-slide pile 1. The traction column 4 is then pre-embedded and fixed to the anti-slide pile 1. This reinforces the anti-slide pile 1, improving its stability during use. Furthermore, the traction column 4 can also pull the passive protection net 2 as a whole via the traction cable 5, increasing its load-bearing capacity and reducing the likelihood of it tilting towards the building, further minimizing the threat to the building below and improving the treatment effect on the dangerous rock slope. Simultaneously, the anti-slide pile 1 reinforces the traction column 4, ensuring its traction effect on the passive protection net 2.
[0042] Furthermore, during the pouring of the concrete layer 12, some concrete will fill the reinforcement hole 41, thereby increasing the interlocking force between the traction column 4 and the anti-slide pile 1, increasing the overall integrity of the two, so that the anti-slide pile 1 has a better stabilizing effect on the traction column 4, and the traction column 4 has a better traction effect on the passive protection net 2.
[0043] In practical use, the anti-slide pile 1 tends to block water from the slope 3, making it difficult for water to penetrate downwards. This leads to water accumulation above the anti-slide pile 1, reducing the stability of the slope 3. Therefore, a drainage pipe 6 is pre-embedded inside the anti-slide pile 1, penetrating the pile and extending along the slope 3's inclination direction. This drainage pipe 6 facilitates the downward flow of water above the anti-slide pile 1, resulting in better drainage and preventing water accumulation above it.
[0044] Reference Figure 2 and Figure 3 Furthermore, during installation, the drain pipe 6 is tied to the reinforcing cage 11 with steel wire. The traction column 4 has a clearance opening, and a connecting block 42 is fixed to the edge of the clearance opening. The connecting block 42 has an upward-opening slot 421. The drain pipe 6 passes through the clearance opening, and a horizontally extending connecting shaft 61 is fixed to the drain pipe 6. The connecting shaft 61 is engaged and rotatably connected within the slot 421.
[0045] Furthermore, during the installation of the drainage pipe 6 and the traction column 4, the drainage pipe 6 provides positioning for the traction column 4, reducing the possibility of the traction column 4 swaying and making it less likely for the traction column 4 to tip over during the subsequent pouring of the concrete layer 12. In addition, while supporting the traction column 4, the drainage pipe 6 can also be rotated to adjust its tilt angle, thus facilitating its installation at a suitable angle for drainage.
[0046] Reference Figure 3 and Figure 4A limiting part 422 is formed at the lower edge of the slot 421. The limiting part 422 extends in an arc shape and fits against the peripheral wall of the connecting shaft 61. A clamping ring 62 is sleeved on and threadedly connected to the connecting shaft 61. A connecting ring groove 621 is formed on the end face of the clamping ring 62 facing the limiting part 422. The connecting ring groove 621 is coaxially arranged with the clamping ring 62, so that when the clamping ring 62 is rotated, the limiting part 422 can be engaged in the connecting ring groove 621.
[0047] During installation, after the drain pipe 6 passes through the traction column 4 and the connecting shaft 61 is engaged in the slot 421, the clamping ring 62 is rotated. The clamping ring 62 can slide toward the connecting block 42, and then the limiting part 422 is engaged in the connecting ring groove 621. This allows the drain pipe 6 and the traction column 4 to be positioned vertically, reducing the possibility of the drain pipe 6 shaking up and down and improving the stability of the drain pipe 6 installation.
[0048] Reference Figure 4 A positioning block 423 is formed on the side of the limiting part 422 facing the connecting shaft 61. Multiple positioning grooves 611 are formed on the peripheral wall of the connecting shaft 61, and the multiple positioning grooves 611 are distributed along the circumference of the connecting shaft 61. During installation, the tilt angle of the drain pipe 6 is adjusted in advance. After the adjustment is completed, when the connecting shaft 61 is snapped into the slot 421, the positioning block 423 can snap into one of the positioning grooves 611, thereby having a rotation limiting effect on the installation of the connecting shaft 61 and the drain pipe 6, improving the stability of the installation of the drain pipe 6, and making it more convenient to tie the drain pipe 6 to the reinforcing cage 11 later.
[0049] Reference Figure 5 The top of the traction post 4 has an insertion hole 43, which is funnel-shaped with its smaller end facing the passive protective net 2. A wedge-shaped plug 44 is inserted into the end of the insertion hole 43 facing away from the passive protective net 2, with the smaller end of the wedge-shaped plug 44 inserted into the insertion hole 43. The end of the traction cable 5 facing the traction post 4 passes through the wedge-shaped plug 44, and the end of the traction cable 5 passing through the wedge-shaped plug 44 splits into two cable connectors 51, or other numbers of cable connectors 51. The cable connectors 51 pass around the wedge-shaped plug 44 and are clamped between the wedge-shaped plug 44 and the inner wall of the insertion hole 43, and the cable connectors 51 extend from the insertion hole 43 to the side of the traction post 4 facing the passive protective net 2. The side wall of the wedge-shaped plug 44 has a receiving groove that can hold the cable connectors 51 in place, thus positioning the cable connectors 51. At this time, the traction cable 5 is clamped and fixed with a clip 52, which abuts against the side of the traction post 4 facing the passive protection net 2, and the clip 52 also clamps the cable connector 51.
[0050] During installation, one end of the traction cable 5 is passed through the wedge-shaped insert 44, and the cable connector 51 is clamped between the wedge-shaped insert 44 and the inner wall of the insertion hole 43. Then, the clamp 52 is fixed to hold the cable connector 51 and the traction cable 5 itself, thus connecting the traction cable 5 to the traction post 4. Finally, the other end of the traction cable 5 is fixed to the post 21, completing the installation of the traction cable 5. The clamp 52 can also be replaced with a U-shaped clip. Furthermore, in actual use, if the tension on the traction cable 5 increases, the tension of the traction cable 5 on the wedge-shaped insert 44 will increase, thereby increasing the clamping effect of the wedge-shaped insert 44 on the cable connector 51, resulting in a better connection between the traction cable 5 and the traction post 4, improving the overall performance.
[0051] At the same time, the clamp 52 can limit the wedge-shaped plug 44 while clamping the cable connector 51 and the traction cable 5, reducing the possibility of the wedge-shaped plug 44 sliding away from the plug hole 43, thereby reducing the possibility of the wedge-shaped plug 44 sliding back and forth, and reducing the possibility of the cable connector 51 being worn.
[0052] Reference Figure 5 A traction column 4 is threaded through and connected to a push bolt 521 from the side opposite to the passive protection net 2. The push bolt 521 passes through the traction column 4 and abuts against the clamp 52. After the clamp 52 is installed, the push bolt 521 is installed on the traction column 4, so that the push bolt 521 abuts against the clamp 52, thereby further increasing the limiting effect on the wedge-shaped insert 44 and improving the stability of the wedge-shaped insert 44 during use.
[0053] In actual installation, two fixed steel cables can be used to form a traction cable 5, so that the end of the traction cable 5 separates into two cable joints 51 after passing through the wedge-shaped insert 44.
[0054] The implementation principle of the combined protection structure for dangerous rock slope treatment in this application embodiment is as follows: During use, the anti-slide piles 1 provide support to the rock mass at the slope 3, improving the stability of the slope 3 and reducing the possibility of collapse. Simultaneously, the passive protection net 2 provides further protection to the slope 3; if gravel rolls off the surface of the slope 3, the passive protection net 2 can block it. Furthermore, the traction columns 4 reinforce the anti-slide piles 1, improving their stability during use; they can also be used to pull the passive protection net 2 as a whole via the traction cables 5, increasing its load-bearing capacity and reducing the possibility of it tilting towards the building side, thereby reducing the threat to the buildings below and improving the treatment effect on the dangerous rock slope.
[0055] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
