DETAILED DESCRIPTION

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0027] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0028] Example 1

[0029] The following is further described in conjunction with specific embodiments. Figures 1-6As shown, the present invention is a geogrid laying device for construction, comprising a laying base 1, a wheel 11 being installed at the bottom of the laying base 1, a pulling handle 12 being provided at one end of the laying base 1, and two mounting seats 13 being provided at the other end of the laying base 1, a reel 14 for reeling in a geomembrane roll being placed between the two mounting seats 13, the reel 14 being an air-expanding roller, and the geomembrane roll being fixed by inflating the reel 14 after the geomembrane roll is sleeved on the reel 14, and then the two ends of the reel 14 are respectively placed on the mounting seats 13 on both sides, and the laying base 1 is pulled by pulling the handle 12, so that the geogrid can be reeled in. The laying base 1 is also provided with a penetration mechanism 2 for vertically inserting positioning steel nails into the ground, the penetration mechanism 2 being located on the side of the reel 14 away from the pulling handle 12, and a placement mechanism 3 for placing positioning steel nails and guiding the positioning steel nails into the penetration mechanism 2 being provided at the top of the laying base 1. The positioning steel nails are distributed in rows on the placement mechanism 3. During the pushing process, the positioning steel nails are introduced into the penetration mechanism 2 one by one, and then inserted into the ground through the penetration mechanism 2, so that the laid geogrid can be fixed.

[0030] Reference Figure 2 、 Figure 3 As shown, the penetration mechanism 2 includes a first support seat 21 and a second support seat 22 mounted between two mounting seats 13. A delivery tube 23 is disposed on both sides of the first support seat 21. The delivery tube 23 is generally flat, allowing the positioning steel nail to move along the extension direction of the delivery tube 23 without deviation. The delivery tube 23 includes an inclined guide tube 231 and a vertical guide tube 232 disposed at the bottom end of the inclined guide tube 231. The second support seat 22 is disposed directly above the vertical guide tube 232. A downward pressing member 24 is disposed on the second support seat 22. A notch 233 for inserting the downward pressing member 24 is provided at the connection between the vertical guide tube 232 and the inclined guide tube 231. After the positioning steel nail enters the conveying pipe 23, it first enters the vertical guide pipe 232 from the inclined guide pipe 231. At this time, the positioning steel nail is vertical, with the bottom end in contact with the ground and the top end located in the vertical guide pipe 232. The pressing member 24 is activated to press the top end of the positioning steel nail, so that the bottom end of the positioning steel nail can be penetrated into the ground. In this embodiment, the pressing member 24 includes a pressing cylinder 241, a pressing seat 242 and a pressing bar 243. The pressing cylinder 241 is fixedly mounted on the second support seat 22. The pressing seat 242 is horizontal and fixedly connected to the piston rod of the pressing cylinder 241. The pressing bar 243 is vertical and fixedly connected to the pressing seat 242. The pressing bar 243 is located just above the notch 233. When the pressing cylinder 241 drives the pressing bar 243 to move through the pressing seat 242, the pressing bar 243 can enter the notch 233 and apply pressure to the positioning steel nail so that the positioning steel nail is inserted into the ground.

[0031] Reference Figure 2 、 Figure 4 As shown, the placement mechanism 3 includes two vertical seats 31, a support shaft 32 is arranged between the two vertical seats 31, and both ends of the support shaft 32 are provided with arc guide rails 33 for placing positioning steel nails, and the end of the arc guide rail 33 away from the support shaft 32 is lower than the end of the arc guide rail 33 close to the support shaft 32 and faces the vertical guide tube 232. A conveying component 34 is provided between the two arc guide rails 33 for blocking the positioning steel nails and conveying the positioning steel nails one by one to the inclined guide tube 231. The positioning steel nails are arranged in rows on the arc guide rail 33. The initial state remains stable under the blocking effect of the conveying component 34. The positioning steel nails have a tendency to move to the lowest end of the arc guide rail 33 under the action of their own weight. When the geogrid needs to be positioned, the conveying component 34 is used to convey one positioning steel nail on the arc guide rails 33 on both sides to the inclined guide tube 231 at the same time. After passing through the inclined guide tube 231, the positioning steel nail can enter the vertical guide tube 232, and then the positioning steel nail can be penetrated into the ground through the pressing piece 24.

[0032] Reference Figure 4 As shown, the conveying assembly 34 includes a conveying shaft 341, which is rotatably installed between the two arc-shaped guide rails 33 and is located at the end of the arc-shaped guide rail 33 away from the support shaft 32. Both ends of the conveying shaft 341 are distributed with multiple toggle pieces 342 along their own circumferential direction. A driving member 4 for driving the conveying shaft 341 to rotate is provided between the pulling handle 12 and one of the arc-shaped guide rails 33. When the driving member 4 drives the conveying shaft 341 to rotate, one of the toggle pieces 342 toggle the positioning steel nail into the inclined guide tube 231. In the initial state, one of the toggle pieces 342 is vertical and located in the arc guide rail 33, which blocks the positioning steel nails. When the positioning steel nails need to be transported to the inclined guide tube 231, the driving member 4 drives the conveying shaft 341 to rotate a specified distance, so that the toggle piece 342 originally located in the arc guide rail 33 leaves the arc guide rail 33, and the positioning steel nails located at the end of the arc guide rail 33 enter the inclined guide tube 231. At the same time, the next toggle piece 342 moves into the arc guide rail 33, blocking the next positioning steel nail, thereby realizing the process of transporting the steel nails in each arc guide rail 33 one by one.

[0033] Reference Figure 4 、 Figure 5As shown, the driving member 4 includes a fixed seat 41 welded to one side of the arc guide rail 33, and a limiting slide groove 411 is provided in the fixed seat 41 along its own length direction, and a sliding block 42 is slidably installed in the limiting slide groove 411, and a return spring 412 is connected between the sliding block 42 and the end wall of the limiting slide groove 411; a rubber sheet 43 is fixedly connected to the top of the sliding block 42, and a rubber block 44 is provided on the conveying shaft 341, and the rubber sheet 43 is in contact with the rubber block 44, and a pulling bar 45 is provided between the rubber sheet 43 and the pulling handle 12. When the pulling bar 45 drives the rubber sheet 43 to move, the rubber sheet 43 abuts against the rubber block 44 and can drive the conveying shaft 341 to rotate through the rubber block 44. When the positioning steel pins in the arc-shaped guide rail 33 need to be output to the inclined guide tube 231, the pull bar 45 is pressed downward, causing the pull bar 45 to pull the rubber sheet 43. Since the pull bar 45 is subjected to downward pressure, the rubber sheet 43 can be tightly attached to the rubber block 44. Therefore, the rubber sheet 43 can be moved while the rubber block 44 is rotated by a specified angle, thereby rotating the conveying shaft 341 and driving the paddle piece 342 to move accordingly. When the pull bar 45 is released, the return spring 412 drives the sliding block 42 back to its initial position, and the rubber sheet 43 moves synchronously. Since the pull bar 45 is no longer subjected to downward pressure, the rubber sheet 43 will not be tightly attached to the rubber block 44 during this process, and thus will not cause the conveying shaft 341 to rotate in the opposite direction.

[0034] Reference Figure 5 As shown, to further enhance the stability of the conveying shaft 341 after it has completed its movement, a blocking member 46 is disposed between the fixed base 41 and the conveying shaft 341 to prevent the conveying shaft 341 from rotating in the opposite direction. The blocking member 46 comprises a ratchet 461 and a pawl 462. The ratchet 461 is coaxially disposed on the conveying shaft 341, and the pawl 462 is rotatably disposed on the fixed base 41. The fixed base 41 is provided with a pressing spring 463 for forcing the pawl 462 to press against the ratchet 461. Due to the limiting action of the pawl 462, the ratchet 461 can only rotate in one direction. Therefore, the conveying shaft 341 can only rotate when the pull bar 45 pulls the rubber sheet 43, and will not rotate at other times, thereby providing high stability and reliability.

[0035] Reference Figure 2 、 Figure 4As shown, the support shaft 32 is rotatably mounted between the two vertical seats 31, and the laying base 1 is provided with a positioning seat 15 for supporting and fixing the position of the arc-shaped guide rail 33. The positioning seat 15 is slidably arranged on the laying base 1 along the width direction of the laying base 1. The top of the positioning seat 15 is provided with a positioning slot 151, and the bottom of the arc-shaped guide rail 33 is provided with a positioning block 331 that matches the shape of the positioning slot 151. During the process of installing the geomembrane roll on the unwinding roller 14, it is necessary to place the unwinding roller 14 on the mounting seat 13 or remove it from the mounting seat 13, and rotate the arc guide rail 33 as a whole upward to avoid the arc guide rail 33 from hindering the placement or removal of the unwinding roller 14; after the installation of the unwinding roller 14 is completed, the arc guide rail 33 is rotated downward and the end of the arc guide rail 33 is placed on the inclined guide tube 231, and then the positioning seat 15 is slid in the direction close to the arc guide rail 33 and the positioning block 331 is inserted into the positioning slot 151, so that the arc guide rail 33 can be positioned, thereby improving the stability of the arc guide rail 33.

[0036] Reference Figure 1 、 Figure 5 As shown, a cutting mechanism 5 is also disposed between the two mounting seats 13. The cutting mechanism 5 includes a cutting assembly 51 for cutting the geogrid and a support plate 52 for supporting the geogrid. The geogrid is sandwiched between the cutting assembly 51 and the support plate 52. The cutting assembly 51 includes a cutting seat 511, within which is a mounting slot 5111. The mounting slot 5111 houses a cutting block 512 and a motor-screw assembly 513 for driving the cutting block 512. The cutting block 512 is provided with a cutting blade 514 on one end facing the support plate 52. When the geogrid needs to be cut after laying, the motor-screw assembly 513 is activated to drive the cutting block 512. The cutting block 512 then drives the cutting blade 514 to move synchronously to cut the geogrid. The support plate 52 is provided with a raised portion 521. A cutting slot 522 is defined along the length of the raised portion 521 for inserting the cutting blade 514. The provision of the raised portion 521 can keep the portion of the geogrid placed on the raised portion 521 in a taut state, thereby facilitating the cutting process.

[0037] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
