[0002] Geocells mainly wrap the soil with vertical sheets to increase the modulus and shear strength of reinforced soil. In order to ensure the quality of geocell measurements, the elastic-viscoplastic properties of geocells need to be tested.

[0003] At present, when testing the elastic-viscoplastic properties of geocells, the method of stretching geocells is often used. By applying a certain pressure to the geocell, the geocell is continuously stretched until it is stretched and broken, thereby obtaining the elastic-viscoplastic data of the geocell. However, in this process, it is necessary to cut out samples of suitable sizes before conducting experiments. In addition, the two ends of the sample need to be fixed on two stretching mechanisms during the experiment. At the same time, the remaining waste after cutting the sample cannot be processed in time.

When measuring the tensile strength of the geocell material, the cut geocell sample is placed on the top surface of the limiting ring 6, and then the telescopic member 14 is started to extend, thereby driving the top plate 2 to descend until the top plate 1 covers the top surface of the bottom plate 2. At this time, the bottom surface of the pressure ring 3 is pressed tightly against the top surface of the geocell sample, thereby forming a closed space between the top surface of the geocell sample and the pressure ring 3. Then the booster 15 is started, and the pressure in the space inside the pressure ring 3 gradually increases. The geocell sample begins to expand after being compressed, and the pressure is continuously applied until the geocell sample ruptures, thereby measuring the tensile strength of the geocell sample.

[0044] The driving mechanism is installed between the top plate 1 and the bottom plate 2 and is used to drive the placement plate 4 to move when the top plate 1 is raised or lowered. The inner walls of the measuring slot 7 adjacent to the entrance and exit are provided with slide grooves 17 arranged along the length direction thereof. The driving mechanism includes two screw rods 11 respectively rotatably connected to the two slide grooves 17, two moving blocks 33 respectively sleeved on the outer shafts of the two screw rods 11, a movable rack 9 installed on the outer wall of the bottom plate 2 on the side facing the entrance and exit through a reset member, and an abutment plate 8 fixed on the top plate 1. One end of the two moving blocks 33 is respectively connected to the bottom plate 2 on the outer wall of the bottom plate 2 on the side facing the entrance and exit. The outer walls of both sides of the placement plate 4 are fixedly connected, one end of the two screws 11 extends to the outside of the bottom plate 2 and is fixed with a transmission gear 10 meshing with the movable rack 9. The bottom surface of the abutment plate 8 is a right-angled triangle structure, and one end of the movable rack 9 abuts against the inclined surface of the abutment plate 8. A mounting groove 35 arranged along the length direction of the movable rack 9 is provided on the outer wall of the bottom plate 2 facing the entrance and exit. The reset member includes a sleeve rod 36 fixed inside the mounting groove 35 along the length direction thereof, a slider 34 movably sleeved on the outer periphery of the sleeve rod 36, and a spring 2. One end of the slider 34 is in contact with the outer wall of the bottom plate 2 facing the entrance and exit. The outer side of the movable rack 9 is fixed, one end of the spring 2 is fixed to the slider 34, and the other end of the spring 2 is fixed to the inner wall of one side of the mounting groove 35. When the screw 11 rotates, the movable block 33 can be driven to move, and the movement of the movable block 33 can drive the placement plate 4 to move. When the inclined surface of the bottom surface of the abutment plate 8 abuts against one end of the movable rack 9, the top plate 1 drops, and the abutment plate 8 drops accordingly, thereby squeezing the movable rack 9 to the side away from the abutment plate 8, and the spring 2 is also compressed. At this time, the movable rack 9 moves and drives the two transmission gears 10 When the movable rack 9 rotates forward, the two screw rods 11 also rotate forward, thereby driving the moving block to move toward the side close to the movable rack 9, and then the placement plate 4 can be gradually retracted into the measuring slot 7. On the contrary, when one end of the movable rack 9 abuts against the inclined surface of the abutment plate 8, as the top plate 1 moves upward, the spring 2 gradually recovers its deformation, thereby driving the movable rack 9 to move toward the side close to the abutment plate 8. At this time, the two screw rods 11 can be driven to flip, thereby driving the placement plate 4 to move to the outside of the placement slot 7, thereby achieving the purpose of automatically popping out the placement plate 4.

[0045] The cutting mechanism includes a fixed platform 29 installed just above the base 19, a cutting plate 27 and a mounting plate 23 fixed on the top of the fixed platform 29, a pressing plate 24 rotatably connected to the outer wall of one side of the mounting plate 23 through a connecting piece, a lifting plate 25 arranged just above the cutting plate 27 and an annular knife 26 installed on the bottom surface of the lifting plate 25, a handle 41 is fixed to the end of the pressing plate 24 away from the mounting plate 23, the lifting plate 25 is installed on the outer wall of the mounting plate 23 through an elastic member, the lifting plate 25 is located below the pressing plate 24, and an abutting column 40 abutting against the bottom surface of the pressing plate 24 is fixed on the top surface of the lifting plate 25, a cutting groove 42 is provided on the top surface of the cutting plate 27, a limiting groove 47 arranged in the vertical direction is provided on the side of the mounting plate 23 close to the pressing plate 24, the elastic member includes a limiting column 46 fixed in the limiting groove 47 in the vertical direction, a movable sleeve is arranged on the limiting column 46, one end of the connecting block 45 is fixedly connected to the lifting plate 25, the top of the spring one is fixedly connected to the bottom of the connecting block 45, and the bottom of the spring one is fixedly connected to the bottom of the limiting groove 47. A connecting groove 39 arranged in the horizontal direction is opened on one side of the mounting plate 23. The connecting member includes a connecting shaft connected to the inside thereof by rotation along the length direction of the connecting groove 39 and a movable block sleeved on the outer periphery of the connecting shaft, and one end of the movable block is fixedly connected to one end of the pressing plate 24 close to the mounting plate 23. When cutting, the geocell material is placed in the cutting groove 42, and then the pressing plate 24 is pressed downward. The pressing plate 24 presses the abutting column 40 downward, thereby causing the lifting plate 25 to descend, and the annular knife 26 descends accordingly and enters the cutting groove 42 to complete the cutting of the geocell material. After the cutting is completed, the handle 41 is released, and under the action of the elastic force of the spring one, the lifting plate 25 automatically bounces upward.

[0046] The crushing mechanism is installed on the fixed platform 29 and is used to crush the waste generated during the cutting process of the cutting mechanism. The bottom surface of the cutting groove 42 is provided with a discharge hole 43, the interior of the fixed platform is provided with a crushing chamber 44, and the top surface of the fixed platform is provided with a through hole connected to the discharge hole 43, and the through hole is connected to the crushing groove. The crushing mechanism includes two crushing rollers 30 arranged in the crushing chamber 44, and both ends of the two crushing rollers 30 are rotatably connected to the crushing chamber 44 through the rotating shaft 22. One end of the rotating shaft 22 of the two crushing rollers 30 close to the side of the support column 12 extends to the outside of the mounting platform 29, and the outer periphery of the two rotating shafts 22 are sleeved with mutually meshing connecting gears, one of which is The rotating shaft 22 on one end of a crushing roller 30 away from the support column 12 also extends to the outside of the mounting platform 29 and is fixed with a handwheel 28. A handle is fixed at a position deviating from the center of the circular surface of one side of the handwheel 28. The setting of the handle is convenient for turning the handwheel 28. A discharge groove is provided at the bottom of the crushing chamber 44. After cutting is completed, the waste is put into the crushing chamber, and then the handwheel 28 is turned by holding the handle, thereby driving the rotating shaft 22 fixed thereto to rotate, and the rotating shaft 22 then drives a crushing roller 30 fixed thereto to rotate, and then the crushing roller 30 drives another crushing roller 30 to rotate in the opposite direction thereof, so that the waste can be crushed for subsequent processing and recycling.

[0047] In this embodiment, the telescopic member 14 is a hydraulic cylinder or an electric push rod.

[0048] The implementation principle of this embodiment is: when measuring the tensile strength of the geocell material, the cut geocell sample is placed on the top surface of the limiting ring 6, and then the telescopic member 14 is started to extend, thereby driving the top plate 2 to descend until the top plate 1 covers the top surface of the bottom plate 2. At this time, the bottom surface of the pressure ring 3 is pressed tightly against the top surface of the geocell sample, thereby forming a closed space between the top surface of the geocell sample and the pressure ring 3, and then the booster 15 is started. The booster 5 conveys air to the inside of the pressure ring 3, so that the pressure in the space inside the pressure ring 3 gradually increases. At this time, the geocell sample begins to expand after being compressed, and the geocell sample is continuously pressurized until it breaks, so that the tensile strength of the geocell sample can be measured;

[0049] When the top plate 1 is lifted, the placement plate 4 is in a pop-up state. At this time, the geocell sample to be tested can be conveniently placed on the top surface of the limit ring 6 in the measuring groove 7. In the process of the top plate 1 descending, when the inclined surface of the bottom surface of the abutment plate 8 abuts against one end of the movable rack 9, the top plate 1 descends, and the abutment plate 8 descends accordingly, thereby squeezing the movable rack 9 to the side away from the abutment plate 8, and the spring 2 is also compressed accordingly. At this time, the movable rack 9 moves and drives the two transmission gears 10 to rotate forward, and the two screws 11 also rotate forward accordingly, thereby driving the moving block to move to the side close to the movable rack 9, and then the placement plate 4 can be gradually retracted into the measuring groove 7 until one end of the movable rack 9 abuts When the long side of one side of the abutment plate 8 is reached, the placement plate 4 has been completely retracted into the inner side of the measuring groove 7, and the continued descent of the abutment plate 8 will not drive the movable rack 9 to move until the top plate 1 covers the top surface of the bottom plate 1. After the measurement is completed, the telescopic member 14 is started to contract, the top plate 1 gradually rises, and the abutment plate 8 moves up synchronously with the top plate 1. When one end of the movable rack 9 moves back to contact the inclined surface of the abutment plate 8, then, as the top plate 1 continues to rise, the spring 2 gradually recovers its deformation, thereby driving the movable rack 9 to move to the side close to the abutment plate 8. At this time, the two screws 11 can be driven to flip, thereby driving the placement plate 4 to move to the outside of the placement groove 7, thereby achieving the purpose of automatically ejecting the placement plate 4.

[0050] By using the cutting mechanism, samples of a size that meets the test requirements can be cut out, and the remaining waste materials can be put into the crushing chamber, and then the handle is held to rotate the hand wheel 28, thereby driving the rotating shaft 22 fixed thereto to rotate, and the rotating shaft 22 in turn drives a crushing roller 30 fixed thereto to rotate, and then the crushing roller 30 drives another crushing roller 30 to rotate in the opposite direction, so that the waste materials can be crushed for subsequent processing and recycling.

[0051] Embodiment 2:

[0052] Combination Figure 3 , Figure 5 and Figure 6The present embodiment is further improved on the basis of the embodiment 1 in that: a cavity 21 is provided inside the support column 12, one end of a rotating shaft 22 close to the support column 12 extends into the cavity 21 and is fixed with a ratchet 37, a piston plate 18 is installed inside the cavity 21, the piston plate 18 divides the inside of the cavity 21 into an air storage cavity located above the piston plate 18 and a buffer cavity located below the piston plate 18, the top of the piston plate 18 is fixedly connected to the top of the cavity 21 through a spring 3, an air delivery pipe 16 connected to the inner side of the measuring groove 7 is fixed to the bottom of the bottom plate 2, the other end of the air delivery pipe 16 extends to the inner side of the air storage cavity, the outer ring of the piston plate 18 is connected to the cavity 21 inner ring is matched, and a tooth plate 20 is fixed to the bottom surface of the piston plate 18. A plurality of ratchet teeth matching the ratchet 37 are installed on the side of the tooth plate 20 close to the ratchet 37. A pressure relief hole connected to the outside is opened at the bottom of the buffer chamber. When the spring three is in a relaxed state, the ratchet teeth are not in contact with the ratchet 37. At this time, the rotation of the crushing roller 30 will not be hindered by the ratchet teeth. When the pressure inside the air storage chamber increases, the piston plate 18 can be driven to descend, so that the ratchet teeth 37 can be driven to rotate forward after the ratchet teeth are engaged with the ratchet 37, and then the crushing roller 30 can be mobilized to rotate, so that the energy of the exhaust gas in the pressure mechanism can be used to drive the crushing roller 30 to rotate.

[0053] The implementation principle of this embodiment is: when the geocell sample is ruptured during the test in the pressure-applying mechanism, a large amount of air will enter the air storage chamber through the air pipe 16 in an instant, and when the pressure in the air storage chamber increases, the piston plate 18 is driven to descend, and the spring three is stretched accordingly. When the ratchet teeth engage with the ratchet 37, the ratchet 37 is driven to rotate during the descent of the piston plate 18. When the piston plate 18 moves downward, the air in the buffer chamber is discharged through the pressure relief hole, and then the air pressure in the air storage chamber will rapidly decrease. Under the action of the spring three, the piston plate 18 gradually moves upward until it returns to its original position. During the upward movement of the piston plate 18, the ratchet teeth do not drive the ratchet 37 to rotate.
