Description

Technical Field

[0001] This utility model relates to the field of road construction technology, and in particular to a roadbed reinforcement device. Background Technology

[0002] Geogrids can be laid to enhance the strength of highway and railway subgrades and reduce subgrade settlement. Geogrids can also be used for foundation treatment in special environments such as slope protection, dams, mining engineering and wetlands. When used for subgrade reinforcement, geogrids form a mesh reinforcement layer in soft soil foundations, which significantly improves the shear strength and overall stiffness of the soil, effectively enhances the tensile strength of the soil, reduces settlement and improves overall stability.

[0003] In local roadbed reinforcement operations, geogrids are laid in a modular combination. The connection of modular geogrids requires the use of tools such as wire, straps, and bolts to connect adjacent geogrids. The connection process is cumbersome and requires a lot of time. For geogrids with frames, it is difficult to change the connection angle between two frame geogrids, which makes it impossible for the geogrid to bend according to the terrain in order to better fit the roadbed.

The centers of the first limiting frame and the second limiting frame are fixed by bolts. The reinforcement frame has a square structure. Both ends of the frame rods of the reinforcement frame are movably connected to hinge seats. The hinge seats are made by hinged connection of two connecting frames.

[0006] Furthermore, the reinforcing frame has an external guide rail inside the frame poles, and a frame guide opening on the outer surface of the frame poles, which connects to the external guide rail.

[0007] Furthermore, two connecting plates are welded together inside the outer guide rail of the frame. The connecting plates are perpendicular to the frame rods of the reinforcing frame, and a connecting plate screw hole is opened through the center of the connecting plate.

[0008] Furthermore, the docking frame is slidably connected inside the frame guide, and a frame guide plate is fixedly connected to the outer end of the docking frame.

[0013] This utility model provides a roadbed reinforcement device, which has the following beneficial effects:

[0014] When the modular frame geogrid of this invention is used for roadbed reinforcement, the geogrid is supported and stretched by the reinforcement frame, which can prevent the modular geogrid from deforming under pressure. The multi-directional tensile geogrid is further reinforced by the first and second limiting frames. It can be used for local roadbed reinforcement, or multiple modules can be spliced ​​together to form a roadbed reinforcement layer with a larger coverage area, thus reinforcing a larger area of ​​the roadbed.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] Example 1: Please refer to Figures 1 to 7 :

[0030] This utility model proposes a roadbed reinforcement device, comprising: a reinforcement frame 1, a multi-directional geogrid 2 fixedly connected inside the reinforcement frame 1, and a first limiting frame 3 and a second limiting frame 4 with a cross-shaped structure welded inside the frame 1. The first limiting frame 3 and the second limiting frame 4 are located above and below the multi-directional geogrid 2, respectively. The multi-directional geogrid 2 has a mesh structure. The first limiting frame 3 and the second limiting frame 4 are fixed at their centers by bolts. The reinforcement frame 1 has a square structure, and hinge seats are movably connected to both ends of the internal support of the frame rods of the reinforcement frame 1. The hinge seats are two connecting frames. 5. The geogrid is made by hinge; the geogrid is supported and stretched by the reinforcing frame 1, which can prevent the modular geogrid from deforming under pressure. The multi-directional geogrid 2 is further reinforced by the first limiting frame 3 and the second limiting frame 4. It can be used for local roadbed reinforcement, or multiple modules can be spliced ​​to form a roadbed reinforcement layer with a larger coverage area to reinforce a larger area of ​​roadbed. The first limiting frame 3 and the second limiting frame 4 are fixed by bolts, which can firmly clamp the multi-directional geogrid 2 and prevent the multi-directional geogrid 2 from falling off.

[0031] In this embodiment, an outer guide rail 101 is provided inside the frame pole of the reinforcing frame 1, and a frame guide opening 102 is provided on the outer surface of the frame pole of the reinforcing frame 1. The frame guide opening 102 is connected to the outer guide rail 101. Two connecting plates 103 are welded inside the outer guide rail 101. The connecting plates 103 are perpendicular to the frame pole of the reinforcing frame 1, and a connecting plate screw hole 104 is provided through the center of the connecting plate 103. The outer guide rail 101 is slidably connected to the connecting frame guide plate 501 and the inner support plate 502 of the guide plate, which plays a guiding role, making the installation of the connecting frame 5 faster and more stable.

[0032] In this embodiment, the docking frame 5 is slidably connected inside the frame guide 102. The outer end of the docking frame 5 is fixedly connected to the frame guide plate 501. The frame guide plate 501 is located inside the outer guide rail 101 of the frame and is perpendicular to the docking frame 5. Two inner support plates 502 are vertically welded to the other side of the frame guide plate 501. The inner support plates 502 are parallel to the connecting block plate 103. The inner support plates 502 and the frame guide plate 501 are slidably connected inside the outer guide rail 101 of the frame. The two docking frames 5 are hinged to form a hinge seat for docking the edges of the two reinforced frames 1. After the two reinforced frames 1 are docked, the two docking frames 5 can rotate and the angle between the two reinforced frames 1 can be adjusted according to the terrain structure so that the reinforced frames 1 can be more stably covered in the roadbed.

[0033] In Example 2, based on Example 1, an inner support plate 502 has a through-hole 503 at its center, which is coaxial with the connecting plate screw hole 104. A connecting frame positioning bolt 504 is screwed into both inner support plate screw holes 503, and its end is screwed into the connecting plate screw hole 104. When docking the two reinforced frames 1, the two docking connecting frames 5 are connected to the frames of the two reinforced frames 1 respectively, so that the connecting frame guide plate 501 is inserted into the outer guide rail 101 of the frame. The docking connecting frame 5 is pushed towards the connecting plate 103, so that the connecting plate 103 fits against the inner support plate screw hole 503. Then, the connecting frame positioning bolt 504 is rotated using a tool, so that the threaded part of the connecting frame positioning bolt 504 is screwed into the connecting plate screw hole 104, thus achieving the fixed installation of the docking connecting frame 5. This allows the two reinforced frames 1 to adjust their angle as the two docking connecting frames 5 are hinged, resulting in a stable docking effect and high docking efficiency.

[0034] The working principle of this embodiment is as follows: First, the reinforcement frame 1 is laid flat in the roadbed that needs to be reinforced. The multi-directional tensile geogrid 2 can increase the strength of the roadbed and reduce the settlement of the roadbed. When a large area of ​​roadbed reinforcement is required, the two adjacent reinforcement frames 1 are brought into contact, so that the edges of the two reinforcement frames 1 are close together. The hinge seat is then taken out, and the two connecting frames 5 in the hinge seat are inserted into the frame guide 102 of the frame rod edge of the two reinforcement frames 1 respectively, and pushed inward so that the connecting plate 103 is attached to the inner support plate screw hole 503. Then, the connecting frame positioning bolt 504 is rotated by a tool so that the threaded part of the end of the connecting frame positioning bolt 504 is screwed into the connecting plate screw hole 104, thereby realizing the fixed installation of the connecting frame 5. The other end of the connecting edge of the two reinforcement frames 1 is connected in the same way so that the two reinforcement frames 1 can adjust the angle with the hinge of the two connecting frames 5, so that the reinforcement frames 1 can bend and adjust with the roadbed structure to more stably fit and reinforce the roadbed.
