Description

Technical Field

[0001] The present invention relates to the technical field of anti-landslide structures, and specifically to a grouting anti-landslide structure for high slope treatment. Background Art

[0002] When constructing railways and highways in collapsible loess areas, a large number of excavations will form high slopes. After the completion of the construction, these high slopes may deform or even collapse. Therefore, it is necessary to use a grouting anti-landslide structure to treat the high slopes to prevent natural disasters such as landslides and collapses. The grouting anti-landslide structure is a treatment method that injects slurry into the slope rock and soil mass to improve the physical and mechanical properties of the rock and soil mass and enhance the stability of the slope.

[0003] For example, in the prior art, the patent with the publication number "CN117488844A" and the patent name "A slope protection structure based on precast steel beams" discloses that both the steel anchor cable seat and the steel web beam are precast parts, which greatly simplifies the construction process of slope protection. Compared with traditional on-site casting, the precast steel beam can be produced in a factory environment, ensuring the manufacturing accuracy and quality. This not only reduces the on-site workload but also shortens the construction period, thereby reducing the overall project cost and material waste. The connection male end and the connection female end achieve quick and accurate alignment and connection of different precast parts. The positioning column of the connection male end is inserted into the positioning hole of the connection female end to complete pre-positioning and pre-connection, greatly improving the connection efficiency of subsequent screws and bolts. At the same time, the connection methods in the horizontal and vertical directions further improve the connection strength and stability of the grid protection system, thus providing more solid and durable protection for the slope. And in the prior art, the patent with the publication number "CN117627003A" and the patent name "An ecological slope grouting reinforcement structure" discloses that through the centering positioner provided on the hollow grouting bamboo tube, it effectively ensures that the bamboo tube is basically located in the middle of the grouting hole after being placed in the grouting hole and after grouting, ensuring the uniformity of grouting. At the same time, it can prevent the bamboo tube from protruding outside the grouting body and affecting its durability. After the slurry solidifies and the strength reaches the design requirements, using the exposed head of the bamboo as a support, installing a lattice, tensioning and anchoring the cable. The cable only abuts against the upper surface of the lattice, and the lattice is pressed and fixed on the surface of the slope by the tension provided by the cable, applying a certain pre-tightening pressure to the slope surface to further improve the stability of the slope rock and soil mass. Then, grass is planted in the cultivation soil of the lattice to form an ecological slope protection.

[0004] Although the anti - landslide structure in the above - mentioned prior art can press and fix the lattice on the surface of the slope by using the tension provided by the cable, applying a certain pre - tightening pressure to the slope surface to further improve the stability of the slope rock and soil mass and thus avoid slope landslides, some high slopes are affected by factors such as excavation or internal rock blocks, making the inclined surface of the high slope not a flat inclined surface, but an uneven inclined surface. When the above - mentioned lattice is used for a high slope with an inclined surface that is not a flat inclined surface, since the side of the lattice close to the high slope is a flat and smooth surface, there will be a gap between the lattice and the high slope, and the sliding mud and stones will fall through the gap. Therefore, the anti - landslide structure mentioned above has poor protection stability and protection effect on high slopes and cannot meet different usage requirements.

[0005] Therefore, we propose a grouting - type anti - landslide structure for high - slope treatment to solve the problems mentioned above. Summary of the Invention

[0006] The purpose of the present invention is to provide a grouting - type anti - landslide structure for high - slope treatment to solve the problem that although the anti - landslide structure in the current market can press and fix the lattice on the surface of the slope by using the tension provided by the cable, applying a certain pre - tightening pressure to the slope surface to further improve the stability of the slope rock and soil mass and thus avoid slope landslides, some high slopes are affected by factors such as excavation or internal rock blocks, making the inclined surface of the high slope not a flat inclined surface, but an uneven inclined surface. When the above - mentioned lattice is used for a high slope with an inclined surface that is not a flat inclined surface, since the side of the lattice close to the high slope is a flat and smooth surface, there will be a gap between the lattice and the high slope, and the sliding mud and stones will fall through the gap. Therefore, the anti - landslide structure mentioned above has poor protection stability and protection effect on high slopes and cannot meet different usage requirements.

[0007] To achieve the above purpose, the present invention provides the following technical solution: A grouting - type anti - landslide structure for high - slope treatment, including a protective net that fits and contacts the inclined surface of the high slope, and an anti - landslide block and an anti - landslide frame are installed on the front side of the protective net. An anti - landslide frame is fixed between two adjacent anti - landslide blocks up and down. A grouting insertion pipe is installed through the anti - landslide block and the protective net, and the grouting insertion pipe is used to insert into the grouting holes of the high slope. And an auxiliary filling and sealing component is arranged on the side of the anti - landslide block close to the protective net, and a gap control component is installed on the side of the anti - landslide frame close to the protective net.

[0008] Preferably, connecting ropes are installed at equal intervals around the protective net, and the other ends of the connecting ropes are connected to fixed cone rods, and the fixed cone rods are used to insert into the high slope to fix the protective net.

[0009] Preferably, a second grouting hole is formed in the outer side above the grouting insertion pipe.

[0010] Preferably, the auxiliary filling and sealing assembly includes a first filling groove and a second filling groove formed in the bottom surface of the anti-landslide block member, one end of the second filling groove is communicated with the second grouting hole, the other end of the second filling groove is communicated with the first filling groove in a "return" shape structure, and second plugging and fixing rods are installed on the outer sides of the four sides of the anti-landslide block member, and one end of the second plugging and fixing rod penetrates through the protective net and is inserted into the high slope.

[0011] Preferably, the gap control assembly includes a close-fitting net installed on the bottom surface of the anti-landslide frame member, a row of arc-shaped second steel wires are installed on the inner side wall of the close-fitting net, and the side surface of the close-fitting net away from the second steel wire is in contact with the protective net, and a first plugging and fixing rod arranged outside the close-fitting net is installed on the bottom surface of the anti-landslide frame member, and the first plugging and fixing rod penetrates through the protective net and is inserted into the high slope.

[0012] Preferably, a water inlet hole is formed in the rear side surface of the anti-landslide frame member, and a water storage cavity is formed inside the front side surface of the anti-landslide frame member, and a filtering and water seepage plate is installed inside the water storage cavity.

[0013] Preferably, connecting pipes are installed on both the left and right sides of the anti-landslide frame member, the water storage cavities in two adjacent anti-landslide frame members are communicated through the connecting pipes at corresponding positions, and the connecting pipe installed on the outer side of the outermost anti-landslide frame member is connected to an external drain pipe.

[0014] Preferably, grooves are formed at equal intervals on the outer side surface of the grouting insertion pipe, and a first grouting hole is formed in the outer side below the grouting insertion pipe.

[0015] Preferably, the grooves and a row of vertically arranged first grouting holes are on the same vertical line.

[0016] Preferably, a piston plate is attached and connected inside the grouting insertion pipe, a first steel wire is fixed to the bottom surface of the piston plate, a guide pipe is installed through the inside of the grouting insertion pipe, the lower end of the guide pipe is inserted into the groove, and the lower end of the first steel wire is inserted into the guide pipe, and both the first steel wire and the guide pipe are arranged in an "L" shape.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: This grouting type anti-landslide structure for high slope treatment avoids the gap between the bottom surface of the anti-landslide block member and the uneven inclined surface of the high slope from being too large, which may cause fallen mud and stones to drop, and facilitates the anti-landslide block member to cooperate with the grouting insertion pipe to perform grouting type anti-landslide treatment operations on the high slope well. The specific content is as follows:

[0018] (1) During grouting, a part of the grout flows into the first filling groove and the second filling groove through the second grouting hole. Therefore, a part of the grout can fill and seal the gap between the bottom surface of the anti-landslide block and the uneven inclined surface of the high slope, thus preventing the gap between the bottom surface of the anti-landslide block and the uneven inclined surface of the high slope from being too large and causing fallen mud and stones to fall. At the same time, it can also improve the stability of the installation between the anti-landslide block and the high slope, facilitating the anti-landslide block to cooperate with the grouting insertion pipe to carry out the grouting-type anti-landslide treatment operation on the high slope;

[0019] (2) The setting of the second steel wire makes the close-fitting net be arranged in a deformable arc shape. Therefore, when the second steel wire and the close-fitting net contact the uneven inclined surface of the high slope, the second steel wire is squeezed and can drive the close-fitting net to deform, and then the bottom surface of the anti-landslide frame can be well attached to the uneven inclined surface of the high slope, reducing the gap between the bottom surface of the anti-landslide frame and the uneven inclined surface of the high slope, thus preventing the gap from being too large and causing fallen mud and stones to fall, so as to facilitate the anti-landslide frame to cooperate with the plants planted inside to carry out the anti-landslide treatment operation on the high slope;

[0020] (3) When the grout in the grouting insertion pipe drives the piston plate to move downward during grouting, the piston plate drives the first steel wire to move downward. Through the setting of the "L"-shaped guide pipe, the lower end of the first steel wire is inserted into the soil inside the high slope, and at the same time, the grout flows into the periphery of the first steel wire through the groove, and then the stability of the installation of the first steel wire and the soil inside the high slope can be improved, thereby further improving the stability of the installation of the grouting insertion pipe, facilitating the grouting insertion pipe to carry out the grouting operation well.

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] See also Figures 1 - 10 , the present invention provides the following technical solutions:

[0034] Embodiment 1: The high slope treatment grouting type anti-landslide structure in this embodiment can not only perform grouting type anti-landslide treatment operations on high slopes with flat inclined surfaces, but also perform grouting type anti-landslide treatment operations on high slopes with non-flat inclined surfaces, thereby meeting different usage requirements and improving the stability and protection effect of anti-landslide treatment on high slopes with non-flat inclined surfaces. For specific structures, please refer to the attached Figures 1 - 6 and attached Figures 8 - 10As shown in the figure, it includes a protective net 1 that fits and contacts the inclined surface of the high slope. Anti-slide slope block members 2 and anti-slide slope frame members 3 are installed on the front side of the protective net 1. An anti-slide slope frame member 3 is fixed between two adjacent upper and lower anti-slide slope block members 2. A grouting insertion pipe 4 is installed through the anti-slide slope block member 2 and the protective net 1. The grouting insertion pipe 4 is used to be inserted into the grouting holes of the high slope. And on one side of the anti-slide slope block member 2 close to the protective net 1, an auxiliary filling and sealing assembly is provided. On one side of the anti-slide slope frame member 3 close to the protective net 1, a gap control assembly is installed. Connecting ropes 101 are installed at equal intervals around the protective net 1, and the other ends of the connecting ropes 101 are connected to fixing cone rods 102. The fixing cone rods 102 are used to be inserted into the high slope to fix the protective net 1.

[0035] A second grouting hole 43 is opened on the outer side above the grouting insertion pipe 4. The auxiliary filling and sealing assembly includes a first filling groove 201 and a second filling groove 202 opened on the bottom surface of the anti-slide slope block member 2. One end of the second filling groove 202 is communicated with the second grouting hole 43, and the other end of the second filling groove 202 is communicated with the first filling groove 201 in a "return" shape structure. Second plugging and fixing rods 15 are installed on the outer sides of the four sides of the anti-slide slope block member 2, and one end of the second plugging and fixing rod 15 penetrates through the protective net 1 and is inserted into the high slope. The gap control assembly includes a close-fitting net 9 installed on the bottom surface of the anti-slide slope frame member 3. A row of arc-shaped second steel wires 14 are installed on the inner side wall of the close-fitting net 9. And on the side of the close-fitting net 9 away from the second steel wires 14, it is in contact with the protective net 1. And on the bottom surface of the anti-slide slope frame member 3, a first plugging and fixing rod 10 arranged outside the close-fitting net 9 is installed. The first plugging and fixing rod 10 penetrates through the protective net 1 and is inserted into the high slope. A water inlet hole 5 is opened on the rear side surface of the anti-slide slope frame member 3. And inside the front side surface of the anti-slide slope frame member 3, a water storage cavity 12 is opened. A filter and water seepage plate 13 is installed inside the water storage cavity 12. Connecting pipes 11 are installed on both the left and right sides of the anti-slide slope frame member 3. The water storage cavities 12 in two adjacent anti-slide slope frame members 3 are communicated through the connecting pipes 11 at the corresponding positions. And the connecting pipe 11 installed on the outside of the outermost anti-slide slope frame member 3 is connected to the external drain pipe. Grooves 42 are opened at equal intervals on the outer side surface of the grouting insertion pipe 4. And a first grouting hole 41 is opened on the outer side below the grouting insertion pipe 4.

[0036] First, use an external hole-digging device to excavate multiple grouting holes on the high slope. Then, the entire anti-slide slope structure can be fabricated according to the actual spacing between the grouting holes, so that the anti-slide slope blocks 2 within the anti-slide slope structure correspond one by one to the positions of the grouting holes. Next, lay the fabricated anti-slide slope structure on the inclined surface of the high slope. At this time, the protective net 1 is in close contact with the inclined surface of the high slope. Insert the fixing cone rods 102 on the outer sides of the four peripheries of the protective net 1 into the corresponding high slope through an external tool, thereby fixing the protective net 1. Then, use a tool to hammer the anti-slide slope blocks 2 and the anti-slide slope frame members 3, so that the second plugging and fixing rods 15 around the anti-slide slope blocks 2 are inserted into the high slope, and the first plugging and fixing rods 10 on the bottom surface of the anti-slide slope frame members 3 are inserted into the high slope. At the same time, the close-fitting net 9 on the bottom surface of the anti-slide slope frame member 3 will come into contact with the uneven inclined surface of the high slope, causing the second steel wire 14 to drive the close-fitting net 9 to deform after being squeezed by the uneven inclined surface of the high slope. Therefore, the second steel wire 14 can drive the deformed close-fitting net 9 to fit well with the uneven inclined surface of the high slope, thereby reducing the gap between the bottom surface of the anti-slide slope frame member 3 and the uneven inclined surface of the high slope, and then avoiding the falling of sliding mud and stones due to too large a gap.

[0037] Next, insert the grouting insertion pipe 4 into the anti-slide slope block 2 with a hollow interior. At this time, the lower end of the grouting insertion pipe 4 is inserted into the grouting hole of the high slope. Then, connect an external grouting pipeline to the upper end of the grouting insertion pipe 4 for the first grouting. The slurry in the grouting insertion pipe 4 is discharged into the high slope through the first grouting hole 41 to form a split. The slurry fills the cracks and pores in the rock and soil mass, improving the integrity. The slurry is injected into the joints and fissures of the rock mass, and the slurry reacts chemically with the joint rock mass medium to generate a cementitious substance with higher strength, thereby changing the mechanical properties of the joint surface and enhancing the stability of the rock mass. It can also block the flow of groundwater, thereby improving the waterproof performance. Then, perform secondary grouting. Since the grouting process is an existing technology, it will not be introduced in detail here. At the same time, part of the slurry is discharged into the first filling groove 201 and the second filling groove 202 on the bottom surface of the anti-slide slope block 2 through the second grouting hole 43. Thus, the slurry in the first filling groove 201 and the second filling groove 202 can fill and seal the gap between the bottom surface of the anti-slide slope block 2 and the uneven inclined surface of the high slope. (When a certain amount of slurry flows into the bottom surface of the anti-slide slope block 2, stop the grouting operation. Therefore, it can avoid the excess slurry from overflowing and blocking the water inlet hole 5. At the same time, a baffle can be found to cover and protect the water inlet hole 5 during grouting to prevent the excess slurry from flowing into the surrounding water inlet holes 5), thereby avoiding the falling of sliding mud and stones due to too large a gap between the bottom surface of the anti-slide slope block 2 and the uneven inclined surface of the high slope, and at the same time improving the installation stability between the anti-slide slope block 2 and the high slope, so as to facilitate the anti-slide slope block 2 to cooperate with the grouting insertion pipe 4 to perform the grouting-type anti-slide slope treatment operation on the high slope.

[0038] Finally, a certain amount of soil can be poured into the anti-landslide frame member 3, and then some plants can be planted in the anti-landslide frame member 3, so that the anti-landslide frame member 3 and the plants planted inside cooperate to perform anti-landslide treatment operations on the high slope very well. Connect the connecting pipes 11 on the outer sides of the anti-landslide frame members 3 on the left and right to the external drainage pipes. When encountering heavy rain during later use, part of the rainwater can enter the anti-landslide frame member 3 through the water inlet holes 5 or directly. Then, the rainwater in the anti-landslide frame member 3 enters the water storage cavity 12 after being filtered by the filter and water-permeable plate 13. Since the water storage cavities 12 in two adjacent anti-landslide frame members 3 are connected through the connecting pipes 11 at corresponding positions, the water in multiple water storage cavities 12 is discharged through the outermost connecting pipe 11 and the drainage pipe. Thus, the impact of rainwater on the high slope can be reduced, and further anti-landslide treatment of the high slope can be carried out.

[0039] Embodiment 2: In the high slope treatment grouting type anti-landslide structure in this embodiment, on the basis of Embodiment 1, the installation stability of the grouting insertion pipe 4 can be further improved. The specific structure is referred to in the attached Figure 7 As shown, the groove 42 and a row of first grouting holes 41 arranged vertically are on the same vertical line. A piston plate 6 is attached and connected inside the grouting insertion pipe 4. A first steel wire 7 is fixed to the bottom surface of the piston plate 6. A guide pipe 8 is installed through the inside of the grouting insertion pipe 4. The lower end of the guide pipe 8 is inserted into the groove 42, and the lower end of the first steel wire 7 is inserted into the guide pipe 8. Both the first steel wire 7 and the guide pipe 8 are arranged in an "L" shape.

[0040] When the type of the grout is a cement-sodium silicate double-liquid grouting material, at this time, the grouting insertion pipe 4 does not need to be pulled out, and the grouting insertion pipe 4 needs to be left inside to form a composite support system, so as to improve the stability of the entire anti-landslide structure. And when the soil in the high slope is relatively soft, the structure of the grouting insertion pipe 4 is designed as shown in the attached Figure 7 As shown, when grout is injected into the grouting insertion pipe 4 at this time, the grout will drive the piston plate 6 to move downward, and then the piston plate 6 drives the first steel wire 7 to move downward. The lower end of the first steel wire 7 passes through the outer side of the grouting insertion pipe 4 through the guide pipe 8 and is inserted into the soil in the high slope. At the same time, the grout in the grouting insertion pipe 4 flows into the groove 42 through the first grouting hole 41, and then the grout in the groove 42 flows to the periphery of the corresponding first steel wire 7 below. Therefore, the connection stability between the first steel wire 7 and the surrounding soil can be improved, and further the installation stability of the grouting insertion pipe 4 can be improved. In order to make the first steel wire 7 come out well, the first steel wire 7 and the guide pipe 8 can also be set to be inclined, so as to complete a series of work.

[0041] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
