Description

Technical Field

[0001] This utility model relates to the technical field of geogrid splicing tools, and more specifically, to a geogrid quick splicing and connection device. Background Technology

[0002] Geogrids, as a new type of geosynthetic material, have been widely used in many geotechnical engineering fields such as road construction, railway engineering, dam protection, and slope reinforcement due to their high strength, corrosion resistance, and good interlocking properties with soil. In the process of road paving, geogrids can effectively enhance the stability of the subgrade, distribute the road surface load, delay the occurrence of reflective cracks, and significantly extend the service life of the road. In railway subgrade treatment, it can prevent lateral displacement of the subgrade soil, improve the bearing capacity of the subgrade, and ensure the safety of railway operation.

[0003] However, the current splicing and connection methods of geogrids have many drawbacks. The traditional binding connection method usually uses iron wire to bind and fix adjacent geogrids. This method is not only cumbersome to operate, but also requires construction workers to spend a lot of time and energy to cut, wrap and tighten the iron wire, which greatly reduces construction efficiency.

[0004] While bolted splicing devices improve connection stability to some extent, the bolted connection process is equally complex. Construction workers need to pre-drill holes in the geogrid, then install bolts and nuts and tighten them. This process requires tools such as wrenches and demands high precision in the drilling position. In field construction environments, this complex procedure and reliance on tools significantly limit construction progress. Therefore, we propose a rapid splicing and connection device for geogrids. Utility Model Content

[0005] The purpose of this invention is to provide a quick splicing and connection device for geogrids to solve the defects mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A rapid splicing and connection device for geogrids includes multiple geogrid bodies, each with multiple exposed holes. Multiple splicing and fixing components are provided between adjacent geogrid bodies. Each splicing and fixing component includes a first insertion rod and a second insertion rod inserted through the corresponding exposed hole. An insertion cone is fixedly installed at the bottom end of both the first and second insertion rods. A color marking plate is fixedly installed on the top of both the first and second insertion rods. An upper force-bearing plate is fixedly installed at the top of both the first and second insertion rods. A horizontally positioned horizontal column is fixedly installed on the top of the first insertion rod. The second insertion rod is sleeved on the horizontal column and slidably connected to it.

[0008] Preferably, the first insertion rod and the second insertion rod are of equal height, and the color marking disk is a colored disk structure.

[0009] Preferably, both the first insertion rod and the second insertion rod abut against one side of the wall of the exposed hole, and the outer diameter of the insertion cone rod decreases sequentially from top to bottom.

[0010] Preferably, the upper force-bearing disk is disc-shaped, and the distance between the upper force-bearing disk and the color marking disk is between 1.5cm and 3cm.

[0011] Preferably, multiple inverted conical rods are fixedly installed on the rod bodies of both the first and second insertion rods, and the inverted conical rods are inclined upward at 45° to 60°.

[0012] Preferably, the second insertion rod is provided with a column hole, and the horizontal column passes through the column hole and is slidably connected to the column hole.

[0013] Preferably, an upper limit protrusion is fixedly installed on the upper surface of the end of the horizontal column rod away from the first insertion rod, and a lower through hole is provided on the bottom wall of the column rod hole, through which the upper limit protrusion protrudes.

[0014] Preferably, when the second insertion rod rotates 180° to the point where the lower through hole is above, the upper limit protrusion and the horizontal column pass through the column hole and the lower through hole. After the upper limit protrusion passes through the lower through hole, the second insertion rod continues to rotate 180° until it is vertically inserted into the soil.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model, by setting an insertion rod, an insertion cone rod, and an exposed hole, allows the splicing and fixing components to be quickly inserted into the geogrid and the soil for fixing operations, realizing rapid splicing between geogrids, facilitating operation, and achieving the effect of improving construction efficiency and shortening project time.

[0017] 2. This utility model, by setting a horizontal column, column hole, upper limit protrusion and lower through hole, allows the two insertion rods to slide and rotate flexibly when spliced, so as to realize reasonable insertion and fixing operation according to fixed position, and achieve the effect of convenient reasonable arrangement according to construction needs.

[0018] 3. By setting a color marking disc and an inverted conical rod, this utility model facilitates the identification of the position of the splicing and fixing components by construction personnel. On the other hand, the inverted conical rod can effectively prevent the insertion rod from loosening, thereby achieving convenient management of splicing operations and improving connection stability. This results in a solid and stable structure that is easy to observe the position of the splicing and fixing components. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-4 This utility model provides a technical solution: a geogrid quick splicing and connection device, including multiple geogrid bodies 1, with multiple exposed holes 10 inside each geogrid body 1. Multiple splicing and fixing components 2 are provided between each pair of adjacent geogrid bodies 1. Each splicing and fixing component 2 includes a first insertion rod 20 and a second insertion rod 21 inserted through the corresponding exposed hole 10. The bottom ends of the first insertion rod 20 and the second insertion rod 21 are fixedly installed with insertion cone rods 22. The outer diameter of the insertion cone rods 22 decreases from top to bottom. During construction, the insertion cone rods 22 at the bottom ends of the first insertion rod 20 and the second insertion rod 21 are aligned with the exposed hole 10 and inserted. The design of the outer diameter of the insertion cone rods 22 decreasing from top to bottom makes the insertion process smoother, allowing the splicing and fixing components 2 to quickly connect with the geogrid body 1 and the soil layer. The first insertion rod 20 and the second insertion rod 21 both abut against one side wall of the exposed hole 10, ensuring the stability of the initial installation.

[0028] In this embodiment, a color marking disk 24 is fixedly installed on the top of the first insertion rod 20 and the second insertion rod 21. The heights of the first insertion rod 20 and the second insertion rod 21 are equal. The color marking disk 24 has a colored disk structure and can be marked with bright colors. The color marking disk 24 facilitates construction personnel to quickly identify the location of the splicing and fixing component 2, thereby improving the accuracy of operation.

[0029] Specifically, an upper force-bearing plate 25 is fixedly installed at the top of both the first insertion rod 20 and the second insertion rod 21. The upper force-bearing plate 25 is disc-shaped, which facilitates the application of force by construction personnel to push the first insertion rod 20 and the second insertion rod 21 into the soil.

[0030] Furthermore, the distance between the upper force-bearing plate 25 and the color marking plate 24 is between 1.5cm and 3cm, allowing the geogrid body 1 to be further bound and fixed using external steel wires at this gap. Specifically, one end of the external steel wire is bound to the geogrid body 1, and the other end of the external steel wire is bound to the gap between the upper force-bearing plate 25 and the color marking plate 24 to achieve a further fixing effect.

[0031] In addition, a horizontal column 26 is fixedly installed on the top of the first insertion rod 20. The second insertion rod 21 is sleeved on the horizontal column 26 and slidably connected to the horizontal column 26. The second insertion rod 21 is provided with a column hole 27. The horizontal column 26 passes through the column hole 27 and slidably connects to the column hole 27, so that the relative positions of the first insertion rod 20 and the second insertion rod 21 can be flexibly adjusted, which is convenient for subsequent splicing operations.

[0032] It is worth noting that multiple inverted cone rods 23 are fixedly installed on the body of the first insertion rod 20 and the second insertion rod 21. The inverted cone rods 23 are set at an upward inclination of 45° to 60°. After being inserted into the soil, the upward inclination of the inverted cone rods 23 effectively prevents the first insertion rod 20 and the second insertion rod 21 from loosening, thereby enhancing the connection stability.

[0033] It is worth noting that an upper limit protrusion 261 is fixedly installed on the upper surface of the end of the horizontal column rod 26 away from the first insertion rod 20. A lower through hole 271 is provided on the bottom wall of the column rod hole 27. The upper limit protrusion 261 protrudes from the lower through hole 271. When the second insertion rod 21 rotates 180° until the lower through hole 271 is above, the upper limit protrusion 261 and the horizontal column rod 26 pass through the column rod hole 27 and the lower through hole 271. After the upper limit protrusion 261 passes through the lower through hole 271, the second insertion rod 21 continues to rotate 180° until it is vertically inserted into the soil. When both the first insertion rod 20 and the second insertion rod 21 are vertically downward, the second insertion rod 21 will not slip off the end of the horizontal column rod 26 due to the blocking effect of the upper limit protrusion 261.

[0034] In this embodiment, a rust-proof layer 28 is provided on the outer surface of the splicing and fixing component 2. The rust-proof layer 28 can play a role in rust prevention and protection, which helps to extend the service life.

[0035] When using the geogrid quick splicing and connection device of this utility model, the first step is to lay the geogrid body 1, arrange multiple geogrid bodies 1 in sequence according to the construction requirements, and reserve splicing space between adjacent bodies.

[0036] Then, the initial installation of the splicing and fixing component 2 is carried out. The second insertion rod 21 is rotated 180° until the lower through hole 271 is at the top. Then, the upper limit protrusion 261 and the horizontal column 26 are passed through the column hole 27 and the lower through hole 271. After the upper limit protrusion 261 passes through the lower through hole 271, the second insertion rod 21 is rotated 180° to a vertical position. When both the first insertion rod 20 and the second insertion rod 21 are vertically downward, the second insertion rod 21 will not slip off the end of the horizontal column 26 due to the blocking effect of the upper limit protrusion 261.

[0037] Next, the insertion cones 22 at the bottom of the first insertion rod 20 and the second insertion rod 21 are aligned with the exposed holes 10 of the geogrid body 1 and inserted. The construction workers apply force with the help of the upper force plate 25 to further insert the first insertion rod 20 and the second insertion rod 21 into the soil, and make the first insertion rod 20 and the second insertion rod 21 abut against the side wall of the exposed hole 10 to ensure stable installation and complete the splicing operation.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
