Description

Technical Field

[0001] The invention relates to the technical field of rural road construction, in particular to a slope retaining support mechanism for rural road construction. Background Art

[0002] Due to the particularity of the geographical environment of rural roads, it is necessary to protect the slope soil during the construction of rural roads to avoid geological disasters such as landslides, collapses, and collapses. Therefore, the use of slope retaining support mechanisms can protect the slopes from damage and erosion by natural forces, thereby ensuring the quality and safety of rural road construction.

[0003] For example, the patent name disclosed in the prior art with the announcement number "CN114775654B" is "A Highway Slope Support Structure", which discloses that through the cooperation of the various water-guiding cavities and water-guiding pipes, it is convenient for workers to use water pumps to guide the water needed by plants to various planting troughs in dry weather, which not only avoids the labor loss of manual watering, but also ensures that plants in every place can be watered. The telescopic water-guiding mechanism can be used to adjust the nozzle to be telescopic, so that the nozzle can be retracted when not in use to avoid the nozzle being eroded by external dust. At the same time, the rotation control mechanism can be used to control the nozzle to rotate and spray after the nozzle is extended, thereby improving the spraying effect of the nozzle, so that the plants in the planting trough can be better hydrated. The water storage tank can be used to collect rainwater for reuse in the later watering. The patent name disclosed in "CN117449330A" is "A Highway Slope Support System", which discloses that support piles pass through a support frame and extend into a highway roadbed. The support piles are hollow pile structures, and their tail ends are open. A top pile is inserted into the support piles, and a movable top block is provided on the side wall of the support pile. When the top pile is inserted into the support pile, the movable top block is pushed out radially outward along the support pile and inserted into the roadbed soil. A horizontal extension plate is provided at the bottom of the support frame. There are multiple horizontal extension plates, and a transverse supporting mechanism is provided between two adjacent horizontal extension plates. The transverse supporting mechanism applies an external force horizontally toward the highway roadbed to the support frame. When the movable top block structure is adopted, the process of driving the top pile into the support pile and pushing out the movable top block is easier, avoiding the situation where the top pile is blocked by hard objects such as gravel in the soil and cannot be driven into the support pile, thereby improving construction efficiency and ensuring the stability of the support frame in the roadbed.

[0004] When the slope retaining support mechanism in the above-mentioned prior art is in use, the supporting piles are passed through the supporting frame and extended into the highway roadbed to perform slope support operations. This will cause the supporting frame and the supporting piles to be fixed. If the supporting frame moves during the support process, the supporting piles will be driven to move together, which will lead to poor stability of the slope support of the entire slope retaining support mechanism. Therefore, we propose a slope retaining support mechanism for rural road construction to solve the above-mentioned problems. Summary of the Invention

This will make the supporting frame and the supporting piles fixed. If the supporting frame moves during the support process, the supporting piles will be driven to move together, which will lead to the poor stability of the entire slope retaining support mechanism in slope support.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a slope retaining support mechanism for rural road construction, comprising a wire mesh assembly fixed to the front side of the slope by an anchor rod, and a grouting plug for inserting into the slope is installed through the interior of the wire mesh assembly, and a sleeve is installed on the outside of the front end of the grouting plug, an outer support frame is installed on the outer side of the wire mesh assembly, and the rear end of the expansion screw inside the outer support frame passes through the wire mesh assembly and is inserted into the slope, and the outer support frame and the sleeve are adjacent to the side surface around the sleeve and slotted with a plug-in frame, and the plug-in frame is snap-connected with the sleeve.

[0007] Preferably, grooves are provided on all four sides of the outer side of the sleeve plate, and the front side of the groove is open.

[0008] Preferably, a first guide rod is symmetrically installed inside the outer supporting frame, and a plug-in frame is slidably connected to the outer side of the first guide rod, and the plug-in frame is inserted into the groove.

[0009] Preferably, a sliding rod is fixed inside the plug-in frame, an extrusion plate is slidably connected to the outside of the sliding rod, the extrusion plate is in contact with the sleeve plate, a fixing piece is installed on one side of the plug-in frame, and a through hole is opened inside the fixing piece.

[0010] Preferably, a rotating plate is installed inside the outer support frame through a rotating rod, a vortex spring is connected to the upper outer side of the rotating rod, one end of the rotating plate is arranged on the rear side of the expansion screw, and a boss is fixed on the outer side of the other end of the rotating plate, and the boss is inserted into the through hole, and the diameter of the through hole is larger than the diameter of the boss.

[0011] Preferably, the outer support frame is arranged in a "well"-shaped structure.

[0012] Preferably, the outer support frame is arranged in a plurality of modular and independent rectangular shapes.

[0013] Preferably, a row of transverse plates is installed on the front side of the outer support frame.

[0014] Preferably, a fixed plate in a mirrored "L" shape is fixed below the outer support frame, and a second guide rod is installed in the internal groove of the horizontal part of the fixed plate, and the outer side of the second guide rod is slidably connected to an auxiliary plate arranged on the front side of the horizontal plate, the highest point of the auxiliary plate is higher than the highest point of the horizontal plate, a guide block is fixed to the front side of the auxiliary plate, and the front side of the guide block is inclined, and a third guide rod is installed in the internal groove of the vertical part of the fixed plate, the outer side of the third guide rod is slidably connected to the support plate, the rear side of the support plate is internally connected to an extrusion roller that is in contact with the guide block, and a row of extended steel bars is fixed to the front side of the support plate.

[0015] Preferably, the outer sides of the sliding rod, the first guide rod, the second guide rod and the third guide rod are all nested and connected with return springs, one end of the return spring on the outer side of the first guide rod is connected to the plug-in frame, one end of the return spring on the outer side of the sliding rod is connected to the extrusion plate, and one end of the return spring on the outer side of the second guide rod is connected to the auxiliary plate.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: when the outer support frame moves in the later stage, the grouting pipe will not be moved with it, thereby improving the stability of the entire slope retaining support mechanism for slope support, preventing slope soil from sliding and affecting rural road construction operations. The specific contents are as follows:

[0017] By installing the expansion screws that pass through the outer support frame inside the slope, the outer support frame can be stably installed on the outside of the slope. The outer support frame and the grouting pipe are set independently. Therefore, when the outer support frame moves in the later stage, the grouting pipe will not move with it. This improves the stability of the slope retaining support mechanism for the slope, and prevents the slope soil from sliding and affecting the rural road construction work.

[0018] At the same time, when the expansion screw is installed in the slope, it pushes the rotating plate, causing the rotating plate to rotate with the rotating rod as the center, thereby separating the protruding column from the fixing part, and then automatically driving the plug-in frame to move outward into the corresponding groove through the stored force of the return spring on the outside of the first guide rod. Therefore, the stored force of the return spring on the outside of the sliding rod automatically drives the extrusion plate to move backward, causing the extrusion plate to apply a backward thrust to the sleeve plate, thereby further improving the stability of the grouting insert in the sleeve plate when inserted into the slope, thereby further improving the stability of the entire slope retaining support mechanism for the slope support.

[0019] The setting of the plug-in frame facilitates the good engagement and connection between the outer support frame and the sleeve plate, thereby facilitating the subsequent separation of the outer support frame and the sleeve plate, so as to facilitate the replacement of the outer support frame or the sleeve plate;

[0020] The external support frame is designed as multiple independent modular frames, which makes it easy to replace a single damaged external support frame, and to transport and carry multiple external support frames, so as to facilitate the subsequent assembly operation;

[0021] The materials laid during highway construction automatically drive the extended steel bars to move downward, so that the extended steel bars drive the extrusion roller to move downward, and the extrusion roller applies a backward thrust to the guide block, thereby causing the guide block to drive the auxiliary plate to move backward, so that the auxiliary plate can apply a backward thrust to the cross plate and the outer support frame, thereby further improving the stability of the outer support frame during installation, facilitating improving the support effect of the outer support frame on the slope, thereby further improving the stability of the slope, and further preventing the slope soil from sliding and affecting the rural road construction operation.

[0034] 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.

[0035] See also Figures 1-11 , the present invention provides the following technical solutions:

[0036] Example 1: The slope retaining support mechanism for rural road construction in this embodiment improves the stability of the slope support and prevents the slope soil from sliding and affecting the rural road construction. For the specific structure, refer to the attached Figures 1-8As shown, it includes a wire mesh component 1 fixed to the front side of the slope by an anchor rod, and a grouting plug 2 for inserting into the slope is installed inside the wire mesh component 1, and a sleeve plate 3 is installed on the outside of the front end of the grouting plug 2, an outer support frame 4 is installed on the outer side of the wire mesh component 1, and the rear end of the expansion screw 5 inside the outer support frame 4 penetrates the wire mesh component 1 and is inserted into the slope, and the outer support frame 4 and the sleeve plate 3 are adjacent to each other. The side surface is grooved and installed with a plug-in frame 6, and the plug-in frame 6 is snap-connected with the sleeve plate 3. The outer side of the sleeve plate 3 is provided with a groove 31, and the front side of the groove 31 is open. The inner side of the outer support frame 4 is symmetrically provided with a first guide rod 7, and the outer side of the first guide rod 7 The side is slidably connected with a plug-in frame 6, and the plug-in frame 6 is inserted into the groove 31. A sliding rod 61 is fixed to the inside of the plug-in frame 6, and an extrusion plate 62 is slidably connected to the outside of the sliding rod 61. The extrusion plate 62 is in contact with the sleeve plate 3. A fixing part 63 is installed on one side of the plug-in frame 6, and a through hole is opened inside the fixing part 63. A rotating plate 8 is installed inside the outer support frame 4 through a rotating rod 81. A vortex spring 82 is connected to the upper outside of the rotating rod 81. One end of the rotating plate 8 is arranged on the rear side of the expansion screw 5, and a boss 83 is fixed to the outside of the other end of the rotating plate 8. The boss 83 is inserted into the through hole. The diameter of the through hole is larger than the diameter of the boss 83. The outer support frame 4 is arranged in a "well" shape.

[0037] First, a hole is drilled at a specific position of the slope using external drilling equipment. There are two types of holes drilled, one is a large hole and the other is a small hole. Then, multiple grouting plugs 2 that pass through the wire mesh component 1 are inserted into the drilled large holes in sequence. Later, slurry is injected into the grouting plugs 2 through the equipment, so that the slurry flows into the slope through the flow hole in the grouting plugs 2, further improving the stability of the installation of the grouting plugs 2. Since this part is a prior art, it will not be introduced in detail here. Then, the anchor rods on the upper and lower sides of the wire mesh component 1 are inserted into the slope for fixation, and then the outer support frame 4 in a "well" shape is laid on the outside of the wire mesh component 1. (At this time, due to the depth of the groove for placing the plug-in frame 6 in the outer support frame 4, The depth is less than the depth of the groove 31, so that the extrusion plate 62 in the plug-in frame 6 is in an extruded state, and the distance between the extrusion plate 62 and the plug-in frame 6 is close. The return spring on the outside of the sliding rod 61 is in an extruded state to store force). Take the expansion screw 5 and insert it into the through groove reserved in the outer support frame 4. Then, rotate the expansion screw 5 while moving backward so that the rear end of the expansion screw 5 is inserted into the small hole in the slope, thereby fixing the outer support frame 4 well. When the expansion screw 5 moves backward, the expansion screw 5 will apply a certain thrust to the rotating plates 8 on both sides, so that the rotating plate 8 rotates with the rotating rod 81 as the center of the circle. The vortex spring 82 stores force, and when the rotating plate 8 rotates, the boss 83 is driven from the fixing piece 63, so that the boss 83 is separated from the fixing piece 63. At this time, the plug-in frame 6 is automatically driven to move outward by the stored force of the return spring on the outside of the first guide rod 7. Then, the plug-in frame 6 stably slides into the corresponding groove 31 on the outside of the first guide rod 7. At this time, the stored force of the return spring on the outside of the sliding rod 61 in the plug-in frame 6 automatically drives the extrusion plate 62 to move backward, so that the extrusion plate 62 moves stably backward on the outside of the sliding rod 61, so that the extrusion plate 62 is in close contact with the sleeve plate 3. (The elastic coefficient of the return spring on the outside of the first guide rod 7 is greater than the elastic coefficient of the return spring on the outside of the sliding rod 61. Therefore, the friction generated when the extrusion plate 62 contacts and moves with the outer support frame 4 can be overcome. Friction, and then the stored force of the return spring on the outside of the first guide rod 7 can well drive the plug-in frame 6 and the extrusion plate 62 to move outward into the corresponding groove 31), and apply a backward thrust to the sleeve plate 3 to prevent the sleeve plate 3 from driving the grouting plug 2 to move in the later stage, thereby further improving the stability of the grouting plug 2 in the sleeve plate 3 when inserted into the slope, thereby further improving the stability of the entire slope retaining support mechanism for slope support, and even if the outer support frame 4 moves in the later stage, since the front side of the groove 31 is opened, the outer support frame 4 will not drive the grouting plug 2 to move together, thereby improving the stability of the entire slope retaining support mechanism for slope support, and preventing the slope soil from sliding and affecting the rural road construction operation.

[0038] Example 2: The slope retaining support mechanism for rural road construction in this embodiment discloses another structure of the outer support frame 4 based on the embodiment 1. The specific structure is shown in the attached figure. Figure 9 As shown, the outer support frame 4 in this embodiment is arranged in a plurality of modular and independent rectangular shapes. Through such a modular design, when the surface of one of the outer support frames 4 is damaged, the single damaged outer support frame 4 can be easily replaced without replacing the entire outer support frame 4. At the same time, it is also convenient to transport and carry multiple outer support frames 4, occupying a smaller area to meet different usage requirements.

[0039] Example 3: The slope retaining support mechanism for rural road construction in this embodiment can further improve the stability of the outer support frame 4 when supporting the slope, and further prevent the slope soil from sliding and affecting the rural road construction work. The specific structure is shown in the attached Figure 10-11 As shown, a row of transverse plates 41 are installed on the front side of the outer support frame 4, and a fixed plate 9 in a mirror image "L" shape is fixed below the outer support frame 4, and the internal slot of the horizontal part of the fixed plate 9 is installed with a second guide rod 10, and the outer side of the second guide rod 10 is slidably connected with an auxiliary plate 11 set on the front side of the transverse plate 41, and the highest point of the auxiliary plate 11 is higher than the highest point of the transverse plate 41, and a guide block 111 is fixed on the front side of the auxiliary plate 11, and the front side of the guide block 111 is arranged in an inclined shape, and the internal slot of the vertical part of the fixed plate 9 is installed with a third guide rod 13, and the third guide rod 13 is installed. A support plate 12 is slidably connected to the outer side of the rod 13, and an extrusion roller 122 that is in contact with the guide block 111 is connected to the inner side of the rear side of the support plate 12. A row of extended steel bars 121 is fixed to the front side of the support plate 12. The outer sides of the sliding rod 61, the first guide rod 7, the second guide rod 10 and the third guide rod 13 are all nested and connected with return springs. One end of the return spring on the outer side of the first guide rod 7 is connected to the plug-in frame 6, one end of the return spring on the outer side of the sliding rod 61 is connected to the extrusion plate 62, and one end of the return spring on the outer side of the second guide rod 10 is connected to the auxiliary plate 11.

[0040] First, the fixing plate 9 is fixed to the road surface next to the slope by screws, and the extended steel bar 121 is set above the rural roadbed. At this time, there is a certain distance between the extended steel bar 121 and the upper surface of the rural roadbed to be constructed. Then, when the rural roadbed is constructed, concrete, cement, sand and gravel and other materials are poured onto the rural roadbed so that the height of the materials is higher than the highest point of the extended steel bar 121. These materials are then compacted and shaped by external equipment. Then, these materials drive the extended steel bar 121 to move downward, and the extended steel bar 121 drives the support plate 12 and the squeezing roller 122 to move downward. When the squeezing roller 122 moves downward, it presses against the guide block 111 with an inclined front side. A backward thrust is applied so that the guide block 111 drives the auxiliary plate 11 to move backward together. At this time, the auxiliary plate 11 moves backward stably on the outside of the second guide rod 10, and then the auxiliary plate 11 contacts the cross plate 41, applying a backward thrust and auxiliary supporting force to the cross plate 41 and the outer support frame 4. Therefore, the stability of the installation of the outer support frame 4 can be further improved, which is convenient for improving the support effect of the outer support frame 4 on the slope, and further improving the stability of the slope support of the entire slope retaining support mechanism, avoiding affecting the later rural road construction operations. At the same time, the extended steel bars 121 can also provide a certain support force for the highway roadbed, which will not affect the highway construction operations, thereby completing a series of tasks.

[0041] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
