Description

Technical Field

[0001] This utility model belongs to the field of disaster prevention and mitigation technology, and specifically relates to a support structure for soil landslide treatment. Background Technology

[0002] In my country, there are a large number of soil slopes in mining projects, water conservancy projects, roadbed projects, foundation pit projects and other projects. Due to the engineering geological conditions of the slope and factors such as precipitation and vibration, slope collapses often occur. Landslides not only cause loss of life and property, but also pose a great threat to personal safety and safe production in the future. Therefore, safe and rapid treatment and restoration of slopes is of great significance.

[0003] There are currently many support structures available for soil landslide control, such as simple backfilling and slope repair, planting bags, retaining walls, anti-slide piles, wire mesh, and grid structures. These support structures can effectively control slopes, but some slopes have poor stability after treatment; others have complex structures, are difficult to construct, costly, and time-consuming, making it impossible to quickly and effectively implement landslide control and restoration. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing a support structure for soil landslide control. The specific technical solution is as follows:

[0005] This utility model provides a support structure for soil landslide control, including a modified slope, a reverse base formed at the bottom of the modified slope, a layer of steel-plastic geogrid laid on the surface of the modified slope, and insertion holes opened between the grid points of the steel-plastic geogrid, into which matching reinforcing bars are inserted; the top surface of the reverse base is formed by backfilling soil and rock materials from bottom to top and compacting them to form multiple reverse compacted layers, and the slope direction and slope angle of each reverse compacted layer are consistent with those of the reverse base, and a layer of steel-plastic geogrid is laid on it, and the steel-plastic geogrids are connected to each other by steel wires.

[0006] As a preferred embodiment of this invention, the base slope angle α of the reverse substrate is 5-10°.

[0007] As a preferred technical solution of this utility model, the slope γ of the treated slope formed by the reverse base and the multi-layer reverse compaction layer is less than the slope β of the sliding surface of the repaired slope.

[0008] As a preferred technical solution of this utility model, the thickness of the reverse compaction layer is 0.5-1.0m, and the compaction degree reaches 0.95 or higher.

[0009] As a preferred technical solution of this utility model, the soil and rock material for backfilling the reverse compaction layer is prepared in a manner of finer material at the top and coarser material at the bottom.

[0010] As a preferred technical solution of this utility model, the insert is made of high-strength steel, with a pointed corner at the bottom and an integral axially connected rib cap at the top, the outer diameter of the rib cap being larger than the outer diameter of the insert.

[0011] As a preferred embodiment of this utility model, a metal gasket adapted to fit the insert is fitted onto the insert rod.

[0012] As a preferred technical solution of this utility model, the modified slope surface is covered by multiple steel-plastic geogrids spliced ​​laterally; the steel-plastic geogrid is a biaxial tensile steel-plastic geogrid, and the protrusions at the joint of two adjacent steel-plastic geogrids are fixedly connected by sleeve compression members.

[0013] As a preferred technical solution of this utility model, the sleeve includes a square sleeve, and the protrusions of two adjacent steel-plastic geogrids are fitted into the square sleeve. The outer surface of the square sleeve is fixedly provided with a figure-eight shaped pressure plate along its horizontal axis. The ends of the pressure plate are symmetrically provided with sleeve holes. The sleeve holes are axially attached to the corresponding metal gaskets, and the inner diameter of the sleeve holes is the same as the inner diameter of the metal gaskets. The reinforcing bars are inserted into the soil layer of the trimmed slope by passing through the corresponding sleeve holes, metal gaskets and insertion holes in sequence.

[0014] As a preferred technical solution of this utility model, the outer surface of the square sleeve is vertically connected with a threaded groove in an integrated manner, and the pressing plate is axially sleeved with the threaded groove through a through hole in its middle, and the thickness of the pressing plate is the same as the height of the threaded groove; a threaded cap is screwed into the threaded groove.

[0015] The beneficial effects of this utility model are:

[0016] This invention improves the structural mechanical strength of the potential sliding surface and enhances the stability of the backfill by laying steel-plastic geogrid on the surface of the repaired slope and inserting reinforcing bars into the soil of the lower repaired slope and the reverse compaction layer of the upper backfill. The reverse compaction layer formed by the reverse base and its upper part has the opposite tendency to the slope direction of the treated slope, thus forming an artificial reverse slope, which can enhance the slope stability.

[0017] In particular, by forming a reverse base at the bottom of the modified slope, this design helps to change the natural sliding tendency of the slope, because the reverse base is opposite to the natural slope direction of the slope, thereby increasing the slope's resistance to sliding.

[0018] The setting of reverse compaction layers, with each layer maintaining the same slope aspect and angle as the reverse base, further enhances the overall stability of the slope. This multi-layer reverse compaction method can effectively disperse the shear stress inside the slope and prevent the slope from collapsing due to internal stress concentration.

[0019] The use of steel-plastic geogrids enhances the overall strength and rigidity of the support structure. This material has good tensile and shear properties, which can effectively distribute the soil pressure on the slope to a larger area, thereby reducing the risk of local slope failure.

[0020] The interlocking holes and reinforcing bars on the steel-plastic geogrid allow it to be more firmly fixed to the slope, preventing displacement due to external forces. The steel wires connecting the steel-plastic geogrids further enhance the connection strength between the two types of geogrids, making the entire support structure more stable and reliable.

[0021] Compared to other complex support structures, such as anti-slide piles, this support structure uses relatively simple materials and construction methods, which can greatly reduce construction difficulty and cost.

[0022] The reverse compaction layer is formed by backfilling soil and stone and compacting it. This construction method is simple and easy to implement, and does not require special construction equipment and technology, so it can greatly shorten the construction cycle.

[0023] The support structure uses environmentally friendly materials that will not cause pollution to the environment. At the same time, the structure can be combined with measures such as vegetation restoration to achieve ecological management and beautification of the slope. Attached Figure Description

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0033] Example 1

[0034] To address the technical problems in the background section, the following support structure for soil landslide control is proposed:

[0035] Combination Figure 1 and Figure 2 As shown, a support structure for soil landslide control includes a modified slope 1, a reverse base formed at the bottom of the modified slope 1, a layer of steel-plastic geogrid 3 laid on the surface of the modified slope, and insertion holes 31 are respectively opened between the grid points of the steel-plastic geogrid 3, and matching reinforcing bars 2 are inserted into the insertion holes 31; the top surface of the reverse base is formed by backfilling soil and rocks and compacting them from bottom to top to form multiple layers of reverse compacted layers 5, and the slope direction and slope angle of each layer of reverse compacted layer 5 are the same as those of the reverse base, and a layer of steel-plastic geogrid 4 is laid on it, and the steel-plastic geogrid 4 and the steel-plastic geogrid 3 are connected by steel wires.

[0036] By adopting the above technical solution, the support structure can effectively improve the structural mechanical strength of the potential sliding surface and enhance the stability of the backfill by laying steel-plastic geogrid 3 on the surface of the modified slope 1 and inserting reinforcing bars 2 into the soil of the lower modified slope 1 and the upper backfill reverse compaction layer 5 respectively. The reverse compaction layer 5 formed by the reverse base and its upper part tends to the opposite direction of the treated slope, forming an artificial reverse slope, which can enhance the slope stability.

[0037] In particular, by forming a reverse base at the bottom of the modified slope, this design helps to change the natural sliding tendency of the slope, because the reverse base is opposite to the natural slope direction of the slope, thereby increasing the slope's resistance to sliding.

[0038] The setting of the reverse compaction layer 5, with each layer having the same slope direction and angle as the reverse base, further enhances the overall stability of the slope; this multi-layer reverse compaction method can effectively disperse the shear stress inside the slope and prevent the slope from collapsing due to internal stress concentration.

[0039] The use of steel-plastic geogrid 3 and steel-plastic geogrid 4 enhances the overall strength and stiffness of the support structure. Both materials have good tensile and shear properties, which can effectively distribute the soil pressure on the slope to a larger area, thereby reducing the risk of local slope failure.

[0040] The combination of the insertion holes 31 and the reinforcing bars 2 on the steel-plastic geogrid 3 allows the steel-plastic geogrid 3 to be more firmly fixed on the slope, preventing it from shifting due to external forces; the steel-plastic geogrid 4 and the steel-plastic geogrid 3 are connected by steel wires, which further enhances the connection strength between the two geogrids, making the entire support structure more stable and reliable.

[0041] Compared to other complex support structures, such as anti-slide piles, this support structure uses relatively simple materials and construction methods, which can greatly reduce construction difficulty and cost.

[0042] The reverse compaction layer 5 is formed by backfilling soil and stone and compacting it. This construction method is simple and easy to implement, and does not require special construction equipment and technology, so it can greatly shorten the construction cycle.

[0043] The support structure uses environmentally friendly materials that will not cause pollution to the environment. At the same time, the structure can be combined with measures such as vegetation restoration to achieve ecological management and beautification of the slope.

[0044] The repaired slope 1 involves excavating and repairing the original landslide body and the soil on the sliding surface. The repaired slope 1 not only requires the complete removal of the soil above the sliding surface, but also the complete removal of the disturbed soil below the sliding surface, and the formation of a reverse base at the bottom.

[0045] like Figure 1 As shown, the base slope angle α7 of the reverse substrate is 5-10°.

[0046] By adopting the above technical solution, the base slope angle α7 should not be too large, generally 5 to 10°. In this way, the reverse base and the multi-layer reverse compaction layer 5 can better utilize the self-weight of the soil to form a stable gravity balance system. This design helps to reduce the sliding force generated by gravity on the slope, thereby improving the overall stability of the slope.

[0047] like Figure 1As shown, the slope γ8 of the treated slope formed by the reverse base and the multi-layer reverse compaction layer 5 is less than the slope β6 of the sliding surface of the repaired slope 1.

[0048] By adopting the above technical solutions, the slope gradient γ8 of the treated slope is less than the structural surface spatial characteristics formed by the slope gradient β6 of the slope after the sliding surface is repaired, which is beneficial to the stability of the slope. This makes the gravity distribution of the slope more reasonable. Under a gentler slope, the component of gravity on the soil and rock on the slope along the slope surface is reduced, thereby reducing the risk of slope sliding.

[0049] like Figure 1 As shown, the thickness of the reverse compaction layer 5 is 0.5-1.0m, and the compaction degree reaches 0.95 or higher.

[0050] By adopting the above technical solution, the reverse compaction layer 5 needs to be fully compacted to ensure the compaction degree of the backfill soil and the dip angle of the reverse compaction layer 5; the thickness of each layer of the reverse compaction layer 5 should not be too large, and 0.5 to 1.0m is more suitable; the top layer of the reverse compaction layer 5 can be consistent with or horizontal with the dip angle of the lower reverse compaction layer 5 according to actual needs.

[0051] The thickness of the reverse compaction layer 5 is controlled within the range of 0.5-1.0m, ensuring that each soil layer has sufficient thickness to resist shear force. At the same time, the compaction degree reaches above 0.95, which means that the voids inside the soil are effectively compressed and the contact between particles is closer, thereby improving the overall strength and shear strength of the soil. This helps to enhance the stability of the slope and prevent the soil from sliding due to shear failure.

[0052] like Figure 1 As shown, the soil and rock material backfilled in the reverse compaction layer 5 is prepared in a fine-to-coarse manner.

[0053] By adopting the above technical solution, the material mixing method of fine particles on top and coarse particles on the bottom helps to form a more stable soil structure. The fine particles (such as fine sand, silt, etc.) on top can form a relatively dense surface layer, which helps to prevent rainwater infiltration and surface runoff from eroding the slope and reduce soil erosion. The coarse particles (such as crushed stone, gravel, etc.) at the bottom can provide better support and enhance the slope's anti-sliding ability. The combination of fine and coarse particles can form a more compact soil particle arrangement, thereby improving the overall shear strength of the soil, which helps to resist the shear failure of the slope under external loads or internal stresses.

[0054] Example 2

[0055] Combination Figures 2-7 As shown, based on the above embodiments, this embodiment further provides the following:

[0056] In this embodiment, as Figures 2-4 As shown, the bottom of the insert 2 (made of high-strength steel) is provided with a sharp corner, and the top of it is integrally axially connected with a rib cap 21, the outer diameter of which is larger than the outer diameter of the insert 2.

[0057] By adopting the above technical solution, the bottom of the reinforcing bar 2 is provided with a sharp corner, which facilitates insertion into the soil and rock and forms an effective anchoring effect; the sharp corner design can increase the friction between the reinforcing bar 2 and the soil and rock and improve the pull-out resistance of the reinforcing bar 2; at the same time, the sharp corner can also break the weak parts in the soil and rock during the insertion process, so that the reinforcing bar 2 is more firmly embedded in the soil.

[0058] The top of the reinforcing bar 2 is axially connected with a reinforcing bar cap 21. The outer diameter of the reinforcing bar cap 21 is larger than that of the reinforcing bar 2, which allows the reinforcing bar 2 to better anchor the steel-plastic geogrid 3 to the surface of the trimmed slope 1. At the same time, the reinforcing bar cap 21 is set to a certain length so that it can be inserted into the backfill reverse compaction layer 5, which can better improve the structural mechanical strength of the potential sliding surface and enhance the stability of the backfill.

[0059] The reinforcing bar 2 is made of high-strength steel, which has excellent mechanical properties and corrosion resistance. It can withstand large tensile and compressive forces and is not prone to breakage or deformation. This helps to enhance the overall stability of the support structure and prevent the slope from sliding or collapsing under external loads or internal stress.

[0060] like Figure 3 and Figure 4 As shown, a metal gasket 22 that is compatible with the insertion rod 2 is fitted on it.

[0061] By adopting the above technical solution, the insert bar 2 is fitted with a metal gasket 22 to increase the contact area with the steel-plastic geogrid 3 and improve the anchoring effect; it also allows the exposed bar cap 21 of the insert bar 2 to be better pressed with the steel-plastic geogrid 3 after being inserted into the soil, and can protect the plastic geogrid 3 from damage during pressing.

[0062] like Figure 4 and Figure 7 As shown, the surface of the modified slope 1 is covered by multiple plastic geogrids 3 spliced ​​laterally; the steel-plastic geogrid 3 is a biaxial tensile geogrid, and the protrusions 32 at the joint of two adjacent steel-plastic geogrids 3 are fixedly connected by sleeve clamps 9.

[0063] By adopting the above technical solution, since the steel-plastic geogrid 3 is packaged in bundles, its width is fixed and its length is very long; during construction, multiple steel-plastic geogrids 3 can be used to lay horizontally spliced ​​according to the width of the slope 1 after the repair.

[0064] Biaxial tensile plastic geogrid adopts a square mesh structure with uniform mesh spacing. This structure can resist soil shear and friction forces, providing a more effective force bearing and diffusion ideal interlocking system for the soil.

[0065] The pressure fitting 9 can firmly fix the joint of two adjacent steel-plastic geogrids 3, preventing the geogrids from shifting or loosening under soil pressure or external loads, which helps to maintain the integrity and stability of the support structure.

[0066] like Figure 5 and Figure 7 As shown, the sleeve 9 includes a square sleeve 91, and the protrusions 32 of two adjacent steel-plastic geogrids 3 are fitted into the square sleeve 91. The outer surface of the square sleeve 91 is fixedly provided with a figure-eight shaped pressing plate 92 along its horizontal axis. The ends of the pressing plate 92 are symmetrically provided with sleeve holes 921. The sleeve holes 921 are axially attached to the corresponding metal gaskets 22, and the inner diameter of the sleeve holes 921 is the same as the inner diameter of the metal gaskets 22. The insert bar 2 passes through the corresponding sleeve holes 921, the metal gaskets 22 and the insertion holes 31 in sequence and is inserted into the soil layer of the trimmed slope.

[0067] By adopting the above technical solution, the pressure fitting 9, through its square sleeve 91 structure, can fit the protrusions 32 of two adjacent steel-plastic geogrids 3 together, realizing the rapid connection between the plastic geogrids 3; the pressure connecting piece 92 and its sleeve hole 921 can cooperate with the metal gasket 22 and be firmly fixed to the plastic geogrid 3 by the reinforcing bar 2; this connection method can enable multiple steel-plastic geogrids 3 to form a more compact and coordinated force-bearing system as a whole; when the slope is subjected to external loads or internal stress, it can better resist deformation and displacement, thereby improving the stability of the slope;

[0068] The use of the pressure fitting 9 simplifies the connection process between two adjacent steel-plastic geogrids 3; construction workers do not need to perform complicated welding, sewing or binding operations, but only need to fit the protrusions 32 of the steel-plastic geogrid 3 into the square sleeve 91, and fix it with the pressure connecting piece 92 in conjunction with the metal gasket 22 and the reinforcing bar 2; this connection method not only improves construction efficiency and reduces construction difficulty, but also reduces safety hazards during construction.

[0069] like Figure 6 As shown, the square sleeve 91 has an integral vertically connected threaded groove 911 in the middle of its outer facade. The pressing plate 92 is axially sleeved with the threaded groove 911 through a through hole 922 in its middle, and the thickness of the pressing plate 92 is the same as the height of the threaded groove 911. A threaded cap 93 is screwed into the threaded groove 911.

[0070] By adopting the above technical solution, the pressure plate 92 is axially sleeved with the threaded groove 911 of the square sleeve 91 through the through hole 922 in its middle, and the threaded cap 93 is screwed into the threaded groove 911. This structure can not only ensure the connection stability between the pressure plate 92 and the square sleeve 91, but also make the pressure plate 92 and the square sleeve 91 detachably connected. In this way, it can be easily disassembled and reinstalled when adjustment or inspection is required, which improves construction efficiency and maintenance convenience.

[0071] Working principle and usage process of this utility model:

[0072] When using this utility model, firstly, the landslide slope is trimmed to form trimmed slope 1, and a reverse base is constructed at its bottom; the construction of the reverse base must ensure that the base slope angle α is within the range of 5-10° to provide stable support;

[0073] Next, a layer of steel-plastic geogrid 3 is laid on the surface of the repaired slope 1. The grid of the steel-plastic geogrid 3 has insertion holes 31 for inserting reinforcing bars 2. The bottom of the reinforcing bars 2 has sharp corners to facilitate insertion into the soil layer, and the top is connected with a reinforcing bar cap 21 to prevent the reinforcing bars 2 from falling off. At the same time, metal gaskets 22 are fitted on the reinforcing bars 2 to increase the contact area with the plastic geogrid 3 and improve the anchoring effect.

[0074] Subsequently, backfilling with soil and rock materials is carried out from bottom to top on the top surface of the reverse foundation, and each layer is compacted to form a multi-layer reverse compaction layer 5. The thickness of each compaction layer is controlled at 0.5-1.0m, and the compaction degree must reach above 0.95. The soil and rock materials should be mixed in a way that is finer at the top and coarser at the bottom to ensure the stability and shear strength of the compaction layer. After each layer of reverse compaction layer 5 is backfilled and compacted, a layer of steel-plastic geogrid 4 is laid on it and connected to the plastic geogrid 3 with steel wires to form an integral support structure. This process is repeated until the top of the slope is reached. The uppermost reverse compaction layer 5 can be aligned with or level with the dip angle of the lower reverse compaction layers 5, depending on actual needs.

[0075] At the joint of two adjacent steel-plastic geogrids 3, a sleeve clamp 9 is used for fixing. The sleeve clamp includes a square sleeve 91 and a clamping plate 92. The protrusions 32 of two adjacent plastic geogrids 3 are fitted into the square sleeve 91. The sleeve hole 921 on the clamping plate 92 is attached to the metal gasket 22. The reinforcing bar 2 passes through the sleeve hole 921, the metal gasket 22 and the insertion hole 31 in sequence and is inserted into the soil layer, which further enhances the stability of the support structure.

[0076] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
