Description

Technical Field

[0001] The utility model relates to the technical field of rail transit, in particular to a slope reinforcement inserting pipe and a slope reinforcement structure. Background Art

[0002] In the existing inclined slope reinforcement structure for geotechnical design engineering, the gripping strength of the reinforcement inserting pipe is not high, resulting in a weak reinforcement effect of the wire mesh on the inclined slope, and reducing the practicability of the inclined slope reinforcement structure for geotechnical design engineering.

[0003] In this regard, after retrieval, the publicly disclosed CN217325414U discloses an inclined slope reinforcement structure for geotechnical design engineering, including: an inclined slope, on the surface of which a reinforcement mesh layer is installed; a telescopic member, the telescopic member for fixing the reinforcement mesh layer is arranged on the inclined slope; a fixing member, the fixing member for fixing the telescopic member is arranged on the surface of the reinforcement mesh layer, and the telescopic member includes a telescopic sleeve arranged on the reinforcement mesh layer; when it is necessary to enhance the connection tightness between the reinforcement mesh layer and the inclined slope, the telescopic sleeve and the telescopic plate are abutted against the reinforcement mesh layer, so that the reinforcement inserting pipe is inserted into the inclined slope, and through the interaction between the piston rod and the air cylinder, gas is generated and expanded in the airbag, and then the fixing thorns are pushed to penetrate into the inclined slope, increasing the gripping strength of the reinforcement inserting pipe and improving the connection tightness between the reinforcement mesh layer and the inclined slope, with convenient installation, time-saving and labor-saving, and improving the practicability of the inclined slope reinforcement structure for geotechnical design engineering.

[0004] After the reinforcement inserting pipe disclosed in the above technology penetrates the reinforcement mesh layer and is inserted into the inclined slope, air is supplied into the airbag through structures such as a piston rod, and the airbag in the reinforcement inserting pipe is expanded to drive a plurality of corresponding fixing thorns to penetrate into the inclined slope for rooting and strengthening the fixing strength. The following deficiencies exist when this structure is in use:

[0005] 1. Since the airbag has a certain flexibility, the expansion direction in the reinforcement inserting pipe is difficult to control. When the geology of the inclined slope is relatively hard, it is difficult to stably penetrate and root for fixation, and the applicability and stability are not ideal;

[0006] 2. It is difficult to retract and reset the fixing thorns by using the airbag expansion method in the subsequent process, which is not convenient for the subsequent recycling work.

[0007] In view of this, this application proposes a slope reinforcement inserting pipe and a slope reinforcement structure. Utility Model Content

[0039] The embodiments of the technical solution of the present invention will be described in detail below with reference to the drawings. The following embodiments are only used to illustrate the technical solution of the present invention more clearly, so they are only examples and cannot be used to limit the protection scope of the present invention.

[0040] Please refer to Figures 1-8The utility model provides a slope reinforcement insert, comprising a tube body 1 and a buckle sleeve 2. One end of the tube body 1 is set as a conical sealing structure 11, and the other end is connected to the buckle sleeve 2. A drill cage 3 is embedded in the tube body 1, and the drill cage 3 includes a fixed plate 31, a rotating shaft 32, a support plate 33, a sliding plate 34, a driven shaft 35 and a drill bit 36. When the insert is inserted into the inclined slope 100 and the buckle sleeve 2 abuts against the surface of the inclined slope 100, the drill bit 36 ​​can be driven to rotate and feed by rotating the rotating shaft 32 to be exposed outside the tube body 1 and drill into the surrounding rock / soil around the tube body 1, and the gripping strength of the insert is increased by drilling and rooting. At the same time, the drill bit 36 ​​in the insert can also be rotated and retracted to be accommodated in the tube body 1, which is convenient for recycling.

[0041] Specifically, see Figures 4-5 , there are at least two fixed disks 31 and they are spaced apart along the axial direction of the tube body 1. The rotating shaft 32 passes through each fixed disk 31 and the buckle sleeve 2 in sequence and is rotatably connected to each fixed disk 31 and the buckle sleeve 2 respectively. In one embodiment, bearings, such as UCFL series seat bearings, can be installed on the fixed disk 31. Since only the fixed disks 31 at both ends of the drill cage 3 are needed to ensure the installation stability of the rotating shaft 32, bearings are not required at the buckle sleeve 2. The two ends of the support plate 33 are fixedly connected to the two adjacent fixed disks 31 respectively. At least one driven shaft 35 is rotatably connected to the support plate 33, and the driven shaft 35 is transmission-connected to the rotating shaft 32 through a reversing assembly 37. A drill bit 36 ​​that rotates synchronously with the driven shaft 35 is also installed on the end of the driven shaft 35 away from the rotating shaft 32. Obviously, multiple driven shafts 35 can be set on each support plate 33 and multiple drill bits 36 can be installed. In order to enhance the structural stability of the drill cage 3, at least two connecting rods that are rotationally symmetrical around the fixed disks 31 can be arranged between two adjacent fixed disks 31, and a cage-like structure is formed by the multiple connecting rods and the fixed disks 31 at both ends. A sliding plate 34 is also arranged between the drill bit 36 ​​and the support plate 33, and the two ends of the sliding plate 34 are respectively slidably connected to the two adjacent fixed disks 31. Preferably, a sliding guide groove 311 that is slidably connected to the end of the sliding plate 34 is opened on the surface of the fixed disk 31 to limit the sliding direction of the sliding plate 34. The driven shaft 35 penetrates the sliding plate 34 and then slides and plugs with the drill bit 36, and at least one driven shaft 35 is threadedly connected to the sliding plate 34 so that the sliding plate 34 slides as the driven shaft 35 rotates. Of course, it is also possible to design multiple driven shafts 35 that are respectively threadedly connected to the same sliding plate 34, but the installation accuracy and smoothness of use need to be considered. In particular, the sliding plate 34 is also movably connected to the rear end of the drill bit 36 ​​so that the drill bit 36 ​​can slide axially along the driven shaft 35 as the sliding plate 34 slides. The specific implementation structure can be referred to in the following embodiments. Accordingly, the outer circumference of the tube body 1 is also provided with through holes 12 corresponding to the extending direction of the drill bit 36, so that the drill bit 36 ​​rotates with the rotation shaft 32 and passes through the corresponding through holes 12, and is rotated and fed to be exposed outside the tube body 1 or rotated and retracted to be accommodated in the tube body 1. Embodiment

[0042] This embodiment aims to provide a commutation assembly 37 suitable for the slope reinforcement inserting pipe. Specifically, please refer to Figure 5 , the commutation assembly 37 includes a first bevel gear sleeved on the outer periphery of the rotating shaft 32 and a second bevel gear sleeved on the outer periphery of one end of the driven shaft 35 close to the rotating shaft 32, and the first bevel gear meshes with the second bevel gear. If the bevel gear commutation assembly 37 provided by this embodiment is adopted, at least two support plates 33 can be provided, and at least two support plates 33 are rotationally symmetric about the rotating shaft 32, and then multiple groups of drill bits 36 can be provided to insert the surrounding rock / soil outside the pipe body 1 from different orientations. Embodiment

[0043] This embodiment aims to provide another commutation assembly 37 suitable for the slope reinforcement inserting pipe. Specifically, two support plates 33 are provided and are parallel to each other. The commutation assembly 37 includes a worm gear sleeved on the outer periphery of the rotating shaft 32 and a worm wheel sleeved on the outer periphery of the driven shaft 35. The worm wheel is clamped between the two parallel support plates 33 and meshes with the worm gear. Among them, the structural form of the worm gear can refer to the utility model CN208963159U. Obviously, if the worm gear and worm commutation assembly 37 provided by this embodiment is adopted, the rotating shaft 32 can be eccentrically arranged relative to the pipe body 1 to ensure that the extending direction of the drill bit 36 intersects with the axis of the pipe body 1. In addition, if a worm gear and worm is used as the commutation assembly 37, drill bits 36 can be installed at both ends of the driven shaft 35, and the driven shaft 35 for driving the sliding plate 34 to slide can be designed with reference to the structure of a bidirectional lead screw, so as to drive the two sliding plates 34 to move towards or away from each other simultaneously. Embodiment

[0044] This embodiment aims to provide a linkage structure between the sliding plate 34 and the driven shaft 35, so that on the basis of the drill bit 36 rotating with the driven shaft 35, it can also slide axially along the driven shaft 35 with the sliding of the sliding plate 34. Please refer to Figure 5Or 8. A retaining ring 361 is provided on the outer wall of the tail end of the drill bit 36. A retaining piece 341 is detachably mounted on the side of the support plate 33 facing the drill bit 36, and the retaining ring 361 is clamped between the retaining piece 341 and the support plate 33. When the driven shaft 35 drives the sliding plate 34 to expand outward, the sliding plate 34 pushes the retaining ring 361 and the drill bit 36 to move outward; when the driven shaft 35 drives the sliding plate 34 to move inward, the retaining piece 341 provided on the sliding plate 34 pulls back the retaining ring 361 and the drill bit 36 to move inward. Optionally, coatings or lubricating greases with enhanced sliding properties can be applied to both sides of the retaining ring 361, so as not to affect the rotational movement of the drill bit 36 along with the driven shaft 35 when pushing or pulling back the drill bit 36. Obviously, the linkage structure between the sliding plate 34 and the driven shaft 35 can also be designed as follows, that is, a bearing is sleeved on the tail end of the drill bit 36, the inner ring of the bearing is fixedly connected to the drill bit 36, and the outer ring of the bearing is fixedly connected to the sliding plate 34, then the same technical effect can also be achieved.

[0045] As a further improvement to the above solution, in order to achieve the synchronous rotation of the drill bit 36 with the driven shaft 35 while not affecting the threaded connection between the driven shaft 35 and the sliding plate 34, the present application also designs a plug-in structure between the driven shaft 35 and the drill bit 36. Specifically, please refer to Figures 7-8 , a slot 362 is provided at the tail end of the drill bit 36, and the narrowest part of the slot 362 is larger than the diameter of the driven shaft 35. A square rotating rod 363 is arranged in the slot 362, and a square sliding groove 351 is opened on the surface of one end of the driven shaft 35 facing the drill bit 36, so that when the driven shaft 35 is inserted into the slot 362, the square rotating rod 363 is plugged into the square sliding groove 351. Among them, the square rotating rod 363 can be plugged into the front end of the drill bit 36 and fixed by a pin or a screw.

[0046] As a further improvement to the above solution, please refer to Figure 3 and 5 , at least one limiting block 313 is further provided on the outer edge of the fixed disk 31, and a limiting groove 13 for slidably connecting with the limiting block 313 is opened on the inner wall of the pipe body 1. Under the joint action of the limiting block 313 and the limiting groove 13, the relative positional relationship between the drill cage 3 and the pipe body 1 is restricted. Specifically, the rotational freedom of the drill cage 3 is restricted to prevent relative rotation between the two, which affects the alignment of the drill bit 36 with the through hole 12. The axial positioning of the drill cage 3 in the pipe body 1 can be achieved by providing ejector rods / ejector blocks on the buckle sleeve 2 and the plugging structure 11, so that the two ejector rods / ejector blocks on both sides respectively abut against the fixed disks 31 at both ends of the drill cage 3.

[0047] As a further improvement to the above solution, a groove 21 is provided on the side of the buckle sleeve 2 away from the pipe body 1. The end of the rotating shaft 32 penetrates through the buckle sleeve 2 and is accommodated in the groove 21. An internal hexagonal rotating sleeve 4 fixedly connected to the end of the rotating shaft 32 is further provided in the groove 21. The front end of the insertion pipe is tapered, which facilitates insertion into the slope by simple knocking or pressing. After insertion, the staff uses a hex wrench to drive the internal hexagonal rotating sleeve to rotate, thereby driving the corresponding rotating shaft 32 to rotate, and then driving the drill bit 36 to drill into the surrounding rock / soil outside the pipe body 1.

[0048] As a further improvement to the above solution, please refer to Figure 2 , to reduce the assembly difficulty of the reinforced insertion pipe, the pipe body 1 can be split into two. Thus, after the drilling cage 3 is assembled, the two half pipe bodies 1 are closed, and the buckle sleeve 2 and the sealing structure 11 are respectively fixedly connected to the pipe body 1 by screws. If the pipe body 1 is made of steel pipe, welding technology can also be used.

[0049] Please refer to Figure 9 , the present utility model further provides a slope reinforcement structure, including a reinforcement mesh layer 7, an outer pressing plate 5, a telescopic plate 6 and a slope reinforcement insertion pipe as described in any one of the above; the reinforcement mesh layer 7 is used for installation on the surface of the inclined slope 100, and at least the top and bottom ends of the inclined slope 100 are respectively provided with outer pressing plates 5 for fixing the reinforcement mesh layer 7. One end of the outer pressing plate 5 is further provided with a telescopic plate 6 that can expand and contract along its own extension direction. The end of the telescopic plate 6 away from the outer pressing plate 5 and the end of the outer pressing plate 5 away from the telescopic plate 6 are both provided with insertion holes, so that the slope reinforcement insertion pipe can be inserted into the inner side of the inclined slope 100 through the corresponding insertion holes to fix the outer pressing plate 5, the telescopic plate 6 and the reinforcement mesh layer 7. Applying this reinforcement insertion pipe to the existing slope reinforcement structure effectively improves the applicability and stability of the slope reinforcement structure.

[0050] The specific usage method of this slope reinforcement structure is as follows: First, lay the reinforcement mesh layer 7 on the surface of the inclined slope 100, and at least set the outer pressing plates 5 on the highest and lowest ends of the reinforcement mesh layer 7. Then, according to the laying range of the reinforcement mesh layer 7, pull and adjust the telescopic length of the telescopic plate 6 in the outer pressing plate 5 to achieve the adjustment of the fixed length. Then, insert the insertion pipe through the insertion hole on the telescopic plate 6 or the outer pressing plate 5 and through the reinforcement mesh layer 7, and insert it into the inclined slope 100. The front end of the insertion pipe is tapered, which facilitates insertion into the slope by simple knocking or pressing. After insertion, the staff uses a hex wrench to drive the internal hexagonal rotating sleeve to rotate, thereby driving the corresponding rotating shaft 32 to rotate, and then driving the drill bit 36 to drill into the surrounding rock / soil outside the pipe body 1. When subsequent unlocking is required, the staff can use a hex wrench to drive the internal hexagonal rotating sleeve to rotate in the reverse direction, so that the drill bit 36 is turned into rotation and retracted into the corresponding pipe body 1. Since this reinforcement insertion pipe has a stable mechanical driving force for retraction, it is convenient for subsequent stable contraction unlocking work, facilitating the recycling of the stabilizing mechanism, and improving the practicability.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the various embodiments of the present invention, and they should all be covered by the scope of the claims and the description of the present invention.
