Description

Technical Field

[0001] The present application relates to the technical field of slope support, and in particular to a slope support structure and a support method. Background Art

[0002] Slope support technology is mainly a technology for supporting and protecting the surrounding environment during civil engineering construction. It is an important measure to improve the quality and safety of foundation pit construction in civil engineering. It also ensures the stability of the soil around the foundation pit and meets the requirement of sufficient space for basement construction, which is a necessary condition for earthwork excavation and basement construction.

[0003] Anchor rods are indispensable for slope support. Existing anchor rods usually include drill bits, hollow anchor pipes, centering devices, connecting sleeves and other structures. The drill bit is installed at one end of the hollow anchor pipe, and mechanical equipment is used to drive the hollow anchor pipe to rotate, so that the drill bit rotates to achieve drilling. However, the diameter of the drill bit in the prior art is larger than the diameter of the anchor rod body. For example, Chinese patent No. CN114197465B discloses a prefabricated prestressed anchor rod construction structure, including a drill bit, a hollow mother anchor pipe and a hollow child anchor pipe. The drill bit is connected to one end of the hollow mother anchor pipe, and the outer wall of the drill bit is provided with grouting holes. The outer walls of the hollow mother anchor pipe and the hollow child anchor pipe are provided with A thread is arranged, the outer diameter of the hollow sub-anchor pipe is smaller than the inner diameter of the hollow mother anchor pipe, one end of the hollow sub-anchor pipe is telescopically arranged inside the hollow mother anchor pipe, the length of the hollow sub-anchor pipe is greater than the length of the hollow mother anchor pipe, and a hole is punched on the slope by rotating the drill bit to form a grouting hole, the diameter of the grouting hole is the same as the diameter of the drill bit, and after the drilling is completed, slurry is introduced into the anchor rod, and finally the slurry flows into the grouting hole through the grouting port on the drill bit, and the anchor rod is fixed when the slurry solidifies.

[0004] In the above-mentioned related technologies, since the diameter of the drill bit is larger than the diameter of the anchor body, the diameter of the grouting hole formed in the slope is the same as the diameter of the drill bit. After the drill bit drills the hole, due to the gap between the inner wall of the grouting hole and the surface of the anchor, when there is no grouting, the mud on the inner wall of the grouting hole will fall off, causing the grouting hole to be blocked, which is very inconvenient when grouting into the grouting hole. Summary of the invention

[0005] In order to facilitate the introduction of slurry into the grouting holes, the present application provides a slope support structure and a support method.

[0006] The present application provides a slope support structure and a support method using the following technical solutions:

[0007] A slope support structure and support method, including an anchor rod inserted into the slope and a drill bit fixed on the anchor rod, the anchor rod and the drill bit are both configured as hollow structures, and a grouting port connected to the drill bit is opened on the anchor rod, the drill bit is provided with a sealing component for sealing the grouting port, the drill bit is provided with a cleaning ring for cleaning the soil between the inner wall of the grouting hole and the outer surface of the anchor rod, and the drill bit is provided with a driving component, and the driving component is used to drive the sealing component to move; when the sealing component no longer seals the grouting port, the slurry in the drill bit enters between the inner wall of the grouting hole and the outer wall of the anchor rod through the grouting port, and the slurry will push the cleaning ring to move along the length direction of the anchor rod.

[0008] By adopting the above technical solution, when the anchor rod and the drill bit are inserted into the soil in the slope, the driving assembly drives the sealing assembly to move, so that the sealing assembly no longer blocks the grouting port, and then slurry is introduced into the anchor rod and the drill bit, and the slurry enters the grouting hole through the grouting port. Then, the slurry flowing into the grouting hole will push the cleaning plate to move. When the cleaning plate moves, it will push the soil between the inner wall of the grouting hole and the outer wall of the anchor rod to move away from the drill bit, thereby reducing the soil in the grouting hole on the one hand, and on the other hand, by blocking the grouting port, it can reduce the possibility of soil entering the drill bit or blocking the grouting port during drilling.

[0009] Optionally, the sealing assembly includes a first sealing plate hinged on the inner wall of the grouting port, a mounting plate slidably connected to the inner wall of the drill bit, and the first sealing plate hinged on the mounting plate, one end of the second sealing plate close to the first sealing plate is hinged to the first sealing plate, and a pushing assembly for pushing the first sealing plate to rotate is provided in the drill bit.

[0010] By adopting the above technical scheme, when the grouting port needs to be opened, the pushing component is directly driven to rotate the first sealing plate, and then the first sealing plate drives the second sealing plate to rotate. At this time, the mounting plate moves away from the anchor rod, and then the grouting port is opened, and the slurry enters the grouting hole through the grouting port, thereby achieving the purpose of facilitating the driving of the first sealing plate to rotate. In addition, due to the rotation of the first sealing plate and the second sealing plate, the first sealing plate and the second sealing plate will rotate into the slope, and then a certain rotation space will be formed between the first sealing plate and the second sealing plate, and the slurry will also enter the rotation space at this time, further improving the strength of the anchor rod and the slope inside the drill bit.

[0011] Optionally, the driving assembly includes a connecting rod hinged on the first sealing plate and a movable plate slidably connected to the drill bit, and the side of the movable plate abuts against the inner wall of the drill bit; when grouting is injected into the anchor rod, the slurry will push the movable plate to move in the drill bit.

[0012] By adopting the above technical solution, when grouting is injected into the anchor rod, the slurry will push the movable plate to move, and the movement of the movable plate will drive the connecting rod to rotate. The rotation of the connecting rod will drive the first sealing plate to rotate. Then, since the first sealing plate and the second sealing plate are hinged, the second sealing plate and the mounting plate will be driven to move, thereby facilitating the opening of the grouting port. At this time, the first sealing plate and the second sealing plate are set at an angle.

[0013] Optionally, a moving block is fixedly mounted on the cleaning ring, and a spiral groove for clamping the moving block is provided on the surface of the anchor rod.

[0014] By adopting the above technical solution, while the slurry pushes the moving plate to move, under the action of the spiral groove and the moving block, the moving plate will rotate, thereby cleaning the soil between the inner wall of the grouting hole and the surface of the anchor rod.

[0016] By adopting the above technical solution, in the initial state, under the action of the support spring, the movable plate will not move, and the grouting port is blocked. Then, when grouting is required, the slurry pushes the movable plate to move. At this time, the thrust of the slurry is greater than the elastic force of the support spring, the support spring is compressed, and then the grouting port is opened, so that the movable plate can be more stable when in use.

[0017] Optionally, an insertion rod is provided on the mounting plate, and the insertion rod is arranged along the axial direction of the anchor rod. The cleaning ring is provided with an insertion groove for inserting the insertion rod, and the anchor rod is provided with a fixing component for fixing the position of the insertion rod.

[0018] By adopting the above technical solution, when drilling a hole in the slope, the insertion rod is placed in the insertion groove, and then the fixing assembly fixes the position of the insertion rod, so that the cleaning ring can be more stable when drilling.

[0019] Optionally, the fixing assembly includes a fixing rod slidably connected to the anchor rod, the fixing rod moves in a direction perpendicular to the axis of the anchor rod, the insertion rod is provided with a fixing groove for inserting the fixing rod, and the inner wall of the anchor rod is provided with an adsorption assembly for placing the fixing rod in the fixing groove.

[0021] Optionally, the adsorption assembly includes an adsorption magnet fixed in the anchor rod and an adsorption plate fixed on the fixed rod, the adsorption magnet fixes the adsorption plate on the inner wall of the anchor rod, and the fixed rod is in the fixed groove. The movable plate is provided with a pushing assembly for pushing the adsorption plate away from the adsorption magnet.

[0022] By adopting the above technical solution, when drilling, the adsorption magnet adsorbs the adsorption plate, and the fixing rod is in the fixing groove, which makes it more convenient to fix the position of the plug-in rod.

[0023] Optionally, the pushing assembly includes a connecting rod fixedly mounted on the movable plate and a pushing rod fixed on the connecting rod, the connecting rod is arranged along the axial direction of the anchor rod, the pushing rod gradually inclines from the direction approaching the movable plate toward the direction away from the connecting rod, a pushing groove is provided on the fixed rod, the pushing rod is in the pushing groove, when the slurry pushes the movable plate to move, it drives the connecting rod and the pushing rod to move, and the pushing rod pushes the fixed rod to move in the direction away from the fixed groove.

DETAILED DESCRIPTION

[0037] The following is combined with Figure 1-5 This application is described in further detail.

[0038] First aspect

[0039] The present application embodiment discloses a slope support structure. Figure 1-5 A slope support structure includes an anchor rod 01 and a drill bit 02 arranged on the anchor rod 01, the drill bit 02 and the anchor rod 01 are both arranged as hollow structures, and a baffle 03 and a nut 04 are arranged at one end of the anchor rod 01 away from the drill bit 02, the baffle 03 is used to abut against the slope, the nut 04 is passed through the anchor rod 01 and is threadedly connected to the anchor rod 01, and the baffle 03 can be abutted against the slope by rotating the nut 04, and an opening is arranged at one end of the anchor rod 01 away from the drill bit 02, so as to facilitate the slurry to be passed into the anchor rod 01 and the drill bit 02 through a grouting pump.

[0040] Reference Figure 1-5 A grouting port 05 is provided on the drill bit 02, through which the slurry is easily passed from the drill bit 02 into the grouting hole 001. At the same time, a plugging component 1 is provided on the drill bit 02, and the plugging component 1 is used to plug the grouting port 05, so that when drilling, the mud can be reduced from entering the drill bit 02 through the grouting port 05, and on the other hand, the mud can be reduced from clogging the grouting port 05.

[0041] Reference Figure 1-5The sealing assembly 1 includes a first sealing plate 11 hinged on the inner wall of the grouting port 05, a mounting plate 12 slidably connected to the drill bit 02, and a second sealing plate 13 hinged on the mounting plate 12. The second sealing plate 13 is hinged on the first sealing plate 11 at one end away from the first sealing plate 11. When the grouting port 05 is sealed, the first sealing plate 11 and the second sealing plate 13 are in the same straight line. When the grouting port 05 needs to be opened, the first sealing plate 11 is directly rotated, and then the first sealing plate 11 drives the second sealing plate 13 to rotate. At this time, the mounting plate 12 will move toward the end face of the drill bit 02. Thereby, the first sealing plate 11 and the second sealing plate 13 are formed in a herringbone structure. During the rotation of the first sealing plate 11 and the second sealing plate 13, a rotation space 06 will be formed between the first sealing plate 11, the second sealing plate 13 and the surface of the drill bit 02. Then, during grouting, the slurry will enter the rotation space 06, and the solidified slurry will support the first sealing plate 11 and the second sealing plate 13. At the same time, since the first sealing plate 11 and the second sealing plate 13 are set at an angle, the first sealing plate 11 and the second sealing plate 13 are rotated into the slope soil at this time, further improving the fixation of the drill bit 02 position, making the anchor rod 01 more firmly in the slope; in this embodiment, three grouting ports 05 and sealing components 1 are provided, and the three sealing components 1 are evenly spaced along the circumference of the drill bit 02. Through the provision of three grouting holes 001, it can be more convenient for the slurry in the drill bit 02 to flow into the grouting holes 001.

[0042] Reference Figure 1-5 A driving assembly 1 is provided in the drill bit 02, and the driving assembly 1 is used to drive the first plugging plate 11 to rotate, so as to facilitate opening the grouting port 05. The driving assembly 1 includes a moving plate 21 slidably connected in the drill bit 02 and a connecting rod 22 hinged on the moving plate 21. The connecting rod 22 is hinged on the first plugging plate 11 at one end away from the moving plate 21, and the side of the moving plate 21 abuts against the inner wall of the drill bit 02. Then, during grouting, the slurry in the drill bit 02 can push the moving plate 21 to move, and the moving plate 21 can drive the connecting rod 22 to rotate when it moves. Under the action of the connecting rod 22, the first plugging plate 11 is pushed to rotate, and the first plugging plate 11 rotates and drives the second plugging plate 13 to rotate when the first plugging plate 11 rotates. At the same time, the second plugging plate 13 drives the mounting plate 12 to slide on the drill bit 02, so as to facilitate opening the grouting port 05. At the same time, a support spring 3 is arranged in the drill bit 02, one end of the support spring 3 is fixed on the movable plate 21, and the other end is fixed on the drill bit 02. Under the action of the support spring 3, when the drill bit 02 and the anchor rod 01 are plugged in, the support spring 3 is used to position the movable plate 21, so that the first sealing plate 11 and the second sealing plate 13 can block the grouting port 05.

[0043] Reference Figure 1-5At the same time, a cleaning ring 31 is sleeved on the drill bit 02, and the outer diameter of the cleaning ring 31 is the same as the outer diameter of the drill bit 02. When the first sealing plate 11 and the second sealing plate 13 are rotated at a certain angle, the grouting port 05 is opened, and the slurry flowing out of the grouting port 05 will push the cleaning ring 31 to move away from the drill bit 02. When the cleaning ring 31 moves, the soil between the inner wall of the grouting hole 001 and the surface of the anchor rod 01 is cleaned, thereby reducing the soil in the grouting hole 001, and making the slurry in the grouting hole 001 better fit to the surface of the anchor rod 01; a moving block 32 is fixedly installed on the cleaning ring 31, and a spiral groove 33 is opened on the surface of the anchor rod 01, and the spiral groove 33 is arranged along the length direction of the anchor rod 01, and the moving block 32 is clamped in the spiral groove 33, and then when the slurry pushes the cleaning plate to move, under the action of the spiral groove 33, the cleaning ring 31 can be moved and rotated at the same time, so that it is more convenient to clean the soil in the grouting hole 001.

[0044] Reference Figure 1-5 A plug rod 4 is arranged on the mounting plate 12, and the plug rod 4 is arranged along the length direction of the anchor rod 01. The plug rod 4 is slidably connected to the drill bit 02. At the same time, a plug groove 41 is opened on the cleaning ring 31, and the plug groove 41 is arranged along the length direction of the anchor rod 01. The plug rod 4 is inserted into the plug groove 41; a fixing groove 42 is opened at one end of the plug rod 4 away from the mounting plate 12, and a fixing component 5 is arranged on the anchor rod 01. The fixing component 5 is used to fix the position of the plug rod 4. At this time, the position of the cleaning ring 31 is fixed by the plug rod, and then when the anchor rod 01 and the drill bit 02 are plugged in, the cleaning ring 31 is more stable.

[0045] Reference Figure 1-5 The fixing assembly 5 includes a fixing rod 51 slidably connected to the anchor rod 01, the fixing rod 51 slides in a direction perpendicular to the axis of the anchor rod 01, and an adsorption assembly 6 is arranged on the inner wall of the anchor rod 01, the adsorption assembly 6 is used to fix the position of the fixing rod 51, when the drill bit 02 and the anchor rod 01 are installed, the fixing rod 51 is in the fixing groove 42, and a pushing assembly 7 is arranged in the anchor rod 01, the pushing assembly 7 is used to drive the fixing rod 51 to disengage from the fixing groove 42, at this time the cleaning plate is no longer fixed, and then it is convenient for the slurry to push the cleaning ring 31 to move, and at the same time, because the fixing rod 51 is in the fixing groove 42 of the insertion rod 4, the position of the mounting plate 12 can be fixed, so that the first sealing plate 11 and the second sealing plate 13 have a better sealing effect on the grouting port 05.

[0046] Reference Figure 1-5 The adsorption component 6 includes an adsorption magnet 61 fixed on the inner wall of the anchor rod 01 and an adsorption plate 62 fixed on the fixing rod 51. The adsorption plate 62 is set to be made of iron material. The adsorption plate 62 can be adsorbed and fixed by the adsorption magnet 61, thereby achieving the purpose of fixing the position of the fixing plate.

[0047] Reference Figure 1-5 The pushing assembly 7 includes a connecting rod 71 and a pushing rod 72. The connecting rod 71 is arranged along the axial direction of the anchor rod 01. One section of the connecting rod 71 is fixed to the movable plate 21, and the other end is fixedly connected to the pushing rod 72. A pushing groove is provided on the fixed rod 51. The pushing groove is provided along the length direction of the fixed rod 51, and the pushing rod 72 is penetrated into the pushing groove. In this embodiment, the pushing rod 72 and the connecting rod 71 are arranged at an angle. The pushing rod 72 gradually moves away from the connecting rod 71 along the length close to the drill bit 02, and then the moving plate 21 can drive the connecting rod 71 to move when it moves. The movement of the connecting rod 71 drives the pushing rod 72 to move, and the fixed rod 51 is driven to move by the pushing rod 72. In this embodiment, the force of the pushing rod 72 pushing the fixed rod 51 is greater than the suction force of the adsorption magnet 61, so that it is convenient for the moving plate 21 to move and drive the fixed rod 51 to disengage from the fixed groove 42.

[0048] Reference Figure 1-5 An elastic rubber plate 8 is fixedly installed on the fixing rod 51, and the elastic rubber plate 8 abuts against the side wall of the fixing groove 42. As the movement of the movable plate 21 drives the mounting plate 12 and the connecting rod 71 to move at the same time, the elastic rubber plate 8 will be compressed without affecting the movement of the insertion rod 4, thereby achieving the purpose of facilitating the fixing rod 51 to disengage from the fixing groove 42.

[0049] The implementation principle of a slope support structure of the embodiment of the present application is as follows: when supporting the slope, the anchor rod 01 and the drill bit 02 are driven to rotate by a drilling machine. When the anchor rod 01 and the drill bit 02 are both inserted into the slope, slurry is introduced into the anchor rod 01 and the drill bit 02 by a grouting pump. Through the flow of slurry, the force of the slurry pushing the movable plate 21 is greater than the force of the supporting spring 3, and then the slurry in the drill bit 02 will push the movable plate 21 to move. When the movable plate 21 moves, it will drive the connecting rod 22 to rotate, and then the first sealing plate 11 is connected to drive the first sealing plate 11 to rotate. The first plugging plate 11 drives the second plugging plate 13 to rotate, and the grouting port 05 is opened at this time. When the moving plate 21 moves, it drives the connecting rod 71 and the pushing rod 72 to move. When the pushing rod 72 moves, it drives the fixed rod 51 to move, so that the force of the pushing rod 72 pushing the fixed rod 51 to move is greater than the suction force of the adsorption magnet 61 on the adsorption plate 62, so that the adsorption plate 62 is easy to separate from the adsorption magnet 61, and then the fixed rod 51 is separated from the fixed groove 42 under the action of the pushing rod 72, and then the position of the cleaning ring 31 is no longer fixed. At this time, the slurry in the drill bit 02 will enter the grouting hole 001 through the grouting port 05, and finally the slurry entering the grouting hole 001 will push the cleaning ring 31 to move, and under the action of the spiral groove 33, the cleaning ring 31 can move and rotate at the same time, so as to facilitate the cleaning of the soil between the inner wall of the grouting hole 001 and the inner wall of the anchor rod 01.

[0050] Second aspect

[0051] A slope support method comprises the following steps:

[0052] S1: insert the drill bit 02 and anchor rod 01 into the slope;

[0053] S2: injecting grout into the anchor rod 01, and the grout pushes the moving plate 21 to move inside the drill bit 02;

[0054] S3: When the moving plate 21 moves, it drives the connecting rod 22 to rotate, and then pushes the first blocking plate 11 and the second blocking plate 13 to rotate, so that the grouting port 05 is opened;

[0055] S4: The slurry enters the grouting hole 001 through the grouting port 05, and then the slurry entering the grouting hole 001 pushes the cleaning ring 31 to move.

[0056] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
