Description

Technical Field

[0001] The invention relates to the technical field of geocells, and in particular to a limiting and fixing device for geocells. Background Art

[0002] In projects such as slope protection, river protection, and vegetation retaining walls, geocells are often used to improve soil stability so that people can carry out greening construction or stabilization construction. When in use, geocells need to be spread out into a mesh shape, and limit fixtures are used to spread the geocells or connect two adjacent geocells to facilitate subsequent filling of loose materials. People often use bent metal rods to act as limit fixtures, but these limit fixtures have poor stability. Especially when filling materials, the limit fixtures are prone to offset or tilting, losing their limit fixing function. It is necessary to propose a solution to the above technical problems.

[0003] As disclosed in the patent document CN111455997A, the device penetrates two adjacent geocells through two sets of vortex rods on the outer sleeve, tightening the two geocells as the outer sleeve rotates. The positioning column is pushed to slide along the outer sleeve, so that the bottom end of the positioning column drives the folding sheet to insert into the soil and fold. Under the limit of the necking structure, the folding sheet is in a folded state and contacts the soil. This process effectively improves the connection effect between the two adjacent geocells, increases the contact area between the folding sheet and the soil, and increases the stability of the limiting and fixing device.

[0004] However, when the above-mentioned device is in use, the folding sheet is folded to increase the contact area with the soil, thereby improving the stability and limiting effect of the limiting and fixing device. Since the soil at the slope protection is relatively loose, the positioning column may still be pulled out of the soil by this method, affecting the efficiency of limiting and fixing the geocell. Summary of the Invention

[0005] The technical problems solved by this solution are:

[0006] How to solve the problem of improving the compactness of the soil around the fixed rod to prevent the fixed rod from being easily pulled out of the soil and affecting the limiting efficiency of the geocell.

[0007] The objectives of the present invention can be achieved through the following technical solutions: A limiting and fixing device for a geocell, comprising a fixing rod, a cavity being defined within the fixing rod, a fixing mechanism being provided at the bottom of the cavity for preventing the fixing rod from being separated from the soil, and a material injection mechanism being provided in the middle of the cavity for improving soil stability;

[0008] The fixing mechanism includes two openings formed on the outer walls on both sides of the fixing plug rod, and a fixing seat is fixedly installed on the inner wall of the fixing plug rod at a position corresponding to the opening, and a transmission rod is movably inserted into the interior of the fixing seat, and two flip units in contact with the soil are symmetrically provided on both sides of the transmission rod; when the transmission rod moves downward, the two flip plates are driven to rotate simultaneously by the shift rod, so that the two clamping plates are flipped and extended from the corresponding openings respectively. In the process of the two clamping plates flipping and extending from the openings, not only the stability of the fixing plug rod in the soil is guaranteed, but also the soil around the fixing plug rod is pushed upward by the clamping plate, so that the fixing plug rod continues to move downward a short distance, thereby further improving the stability of the fixing plug rod in the soil.

[0009] A further technical improvement of the present invention is that the flip unit includes a card plate rotatably connected to the inner wall of the fixed plug rod through a pin shaft, the bottom of the card plate is in contact with the fixed seat, and an inclined flip plate is fixedly installed on the top of the card plate, a slide groove is provided on the front of the flip plate, a shift rod is fixedly installed in the middle of the transmission rod, the shift rod is movably connected to the two slide grooves, and the size of the card plate is smaller than the size of the opening.

[0010] A further technical improvement of the present invention is that: a baffle is fixedly installed on the middle part of the transmission rod, a thrust spring is elastically arranged between the baffle and the fixed seat, a limit plate for guiding the transmission rod is also fixedly arranged on the inner wall of the fixed plug rod, the limit plate is in contact with the baffle, a magnet block is fixedly installed on the bottom of the transmission rod, and an iron plate corresponding to the position of the magnet block is fixedly installed on the bottom of the inner wall of the fixed plug rod.

[0011] A further technical improvement of the present invention is that: the injection mechanism includes a second piston fixedly connected to the top of the transmission rod, the second piston is slidably connected to the inner wall of the fixed plug rod, a first piston is slidably provided on the inner wall of the fixed plug rod above the second piston, a feed hole is provided on the side wall of the fixed plug rod between the first piston and the second piston, and a plurality of discharge holes are provided on the inner wall of the fixed plug rod below the second piston; the fixed plug rod is inserted into the soil by an external pushing device, and the knob is turned so that the threaded rod pushes the first piston to move slowly downward, and when the first piston moves below the feed hole, the first piston continues to move downward so that the first piston and the second piston are in contact. The air pressure in the area between the first and second pistons increases, thereby pushing the second piston downward, providing a downward thrust for the transmission rod. After the second piston moves to the bottom of the several discharge holes, due to the influence of the air pressure in the area between the first and second pistons, the diluted soil solidifier is first sprayed out from the several discharge holes to spray the soil around the fixed plug. After the air pressure drops, the diluted soil solidifier flows out from the several discharge holes, soaks the soil below it along the outer wall of the fixed plug, and cooperates with the external soil compacting tool to compact the soil around the fixed plug to avoid the situation where the fixed plug is loosened and thus pulled out of the soil, thereby improving the stability of the fixed plug.

[0012] A further technical improvement of the present invention is that the inner diameter of the feed hole is smaller than the thickness of the first piston.

[0013] A further technical improvement of the present invention is that a fixed block is fixedly installed on the top of the cavity of the fixed insertion rod, a threaded rod is connected to the internal longitudinal thread of the fixed block, a knob is fixedly installed on the top of the threaded rod, and the bottom of the threaded rod is rotatably connected to the top of the first piston.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] When the present invention is in use, the fixed plug rod is inserted into the soil by an external pushing device, and the knob is turned to cause the threaded rod to push the first piston to move slowly downward. When the first piston moves to the bottom of the feed hole, the first piston continues to move downward, so that the air pressure in the area between the first piston and the second piston becomes larger, thereby pushing the second piston to move downward, providing a downward thrust for the transmission rod. After the second piston moves to the bottom of several discharge holes, due to the influence of the air pressure in the area between the first piston and the second piston, the diluted soil solidifying agent is first sprayed from the several discharge holes to spray the soil around the fixed plug rod. After the air pressure is reduced, the diluted soil solidifying agent flows out from the several discharge holes, soaks the soil below it along the outer wall of the fixed plug rod, and cooperates with the external soil compacting tool to compact the soil around the fixed plug rod to avoid the situation where the soil is loose and the fixed plug rod is pulled out of the soil, thereby improving the stability of the fixed plug rod.

[0016] When the present invention is in use, when the transmission rod moves downward, the two flip plates are driven to rotate simultaneously by the shifting rod, so that the two clamping plates are flipped and extended from the corresponding openings respectively. In the process of the two clamping plates flipping and extending from the openings, not only the stability of the fixed insertion rod in the soil is guaranteed, but also the soil around the fixed insertion rod is pushed upward by the clamping plates, so that the fixed insertion rod continues to move downward a short distance, thereby further improving the stability of the fixed insertion rod in the soil.

[0026] See also Figure 1-Figure 4 As shown, the above-mentioned fixing mechanism 4 includes two openings 403 opened on the outer walls on both sides of the fixing plug rod 5, and a fixing seat 405 is fixedly installed at the position of the inner wall of the fixing plug rod 5 corresponding to the opening 403, and a transmission rod 401 is movably inserted inside the fixing seat 405. Two flip units in contact with the soil are symmetrically arranged on both sides of the transmission rod 401; when the transmission rod 401 moves downward, the two flip plates 409 are driven to rotate simultaneously by the shift rod 407, so that the two clamping plates 406 are flipped and extended from the corresponding openings 403 respectively. In the process of the two clamping plates 406 flipping and extending from the openings 403, not only the stability of the fixing plug rod 5 in the soil is guaranteed, but also the soil around the fixing plug rod 5 is pushed upward by the clamping plates 406, so that the fixing plug rod 5 continues to move downward a short distance, further improving the stability of the fixing plug rod 5 in the soil.

[0027] See also Figure 2 and Figure 3 As shown, the above-mentioned flip unit includes a card plate 406 that is rotatably connected to the inner wall of the fixed plug rod 5 through a pin shaft 408, the bottom of the card plate 406 is in contact with the fixed seat 405, and the top of the card plate 406 is fixedly installed with an inclined flip plate 409, and a slide groove 410 is provided on the front of the flip plate 409. A shift rod 407 is fixedly installed in the middle of the transmission rod 401, and the shift rod 407 is movably connected to the two slide grooves 410. The size of the card plate 406 is smaller than the size of the opening 403.

[0028] See also Figure 2 and Figure 4 As shown, a baffle 411 is fixedly installed in the middle of the above-mentioned transmission rod 401, and a thrust spring is elastically arranged between the baffle 411 and the fixed seat 405.

[0029] See also Figure 1 and Figure 5As shown, the above-mentioned injection mechanism 3 includes a second piston 304 fixedly connected to the top of the transmission rod 401, the second piston 304 is slidably connected to the inner wall of the fixed plug rod 5, and the first piston 301 is slidably provided on the inner wall of the fixed plug rod 5 above the second piston 304. A feed hole 302 is provided on the side wall of the fixed plug rod 5 between the first piston 301 and the second piston 304, and a plurality of discharge holes 303 are provided on the inner wall of the fixed plug rod 5 below the second piston 304; the fixed plug rod 5 is inserted into the soil by an external pushing device, and the knob 7 is turned to make the threaded rod 1 push the first piston 301 to move slowly downward. When the first piston 301 moves below the feed hole 302, the first piston 301 continues to move downward so that the first piston 301 and the second piston The air pressure in the area between 304 increases, thereby pushing the second piston 304 to move downward, providing a downward thrust for the transmission rod 401. After the second piston 304 moves to the bottom of the several discharge holes 303, due to the influence of the air pressure in the area between the first piston 301 and the second piston 304, the diluted soil solidifier is first sprayed out from the several discharge holes 303 to spray the soil around the fixed plug 5. After the air pressure is reduced, the diluted soil solidifier flows out from the several discharge holes 303, soaks the soil below it along the outer wall of the fixed plug 5, and cooperates with the external soil compacting tool to compact the soil around the fixed plug 5 to avoid the situation where the soil is loose and the fixed plug 5 is pulled out of the soil, thereby improving the stability of the fixed plug 5.

[0030] See also Figure 5 As shown, the inner diameter of the feed hole 302 is smaller than the thickness of the first piston 301 .

[0031] See also Figure 1 and Figure 5 As shown, a fixing block 6 is fixedly installed on the top of the cavity of the above-mentioned fixed insertion rod 5, and the internal longitudinal thread of the fixing block 6 is connected to the threaded rod 1, and a knob 7 is fixedly installed on the top of the threaded rod 1, and the bottom of the threaded rod 1 is rotatably connected to the top of the first piston 301.

[0032] See also Figure 1 As shown, the outer walls on both sides of the top of the above-mentioned fixed insertion rod 5 are symmetrically provided with limiting hooks 2 for fixing two adjacent geocells.

[0033] Working principle: When the present invention is in use, first, a certain amount of diluted soil solidifier is injected into the area between the first piston 301 and the second piston 304 from the feed hole 302 through an external pipe, so that the liquid level of the diluted soil solidifier is half of the distance between the first piston 301 and the second piston 304, a through hole is opened on the geocell unit where two adjacent geocells need to be connected, and the two limit hooks 2 on the fixed plug rod 5 are respectively engaged with the two through holes, and the fixed plug rod 5 is inserted into the soil through an external pushing device, and the knob 7 is turned to make the threaded rod 1 push the first piston 301 to move slowly downward. When the first piston 301 moves to the bottom of the feed hole 302, the first piston 301 continues to move downward, so that the air pressure in the area between the first piston 301 and the second piston 304 increases, thereby pushing the second piston 304 to move downward, providing a downward thrust for the transmission rod 401, and when the magnet block 412 is magnetically connected to the iron plate 404, at this time, the second piston 304 moves to the bottom of the plurality of discharge holes 303. The air pressure in the area between the plug 301 and the second piston 304 causes the diluted soil solidifier to be first sprayed out from the plurality of discharge holes 303 and sprayed on the soil around the fixed plug 5. After the air pressure is reduced, the diluted soil solidifier flows out from the plurality of discharge holes 303 and wets the soil below the fixed plug 5 along the outer wall of the fixed plug 5. The soil around the fixed plug 5 is compacted in cooperation with the external soil compacting tool to prevent the loose soil from causing the fixed plug 5 to be pulled out of the soil, thereby improving the stability of the fixed plug 5. When the transmission rod 401 moves downward, the two flip plates 409 are driven to rotate simultaneously by the shift rod 407, so that the two clamping plates 406 are flipped and extended from the corresponding openings 403 respectively. In the process of the two clamping plates 406 flipping and extending from the openings 403, not only the stability of the fixed plug 5 in the soil is ensured, but also the soil around the fixed plug 5 is pushed upward by the clamping plates 406, so that the fixed plug 5 continues to move downward a short distance, further improving the stability of the fixed plug 5 in the soil.
