TECHNICAL FIELD
[0001] The present application relates to the technical field of greening, in particular to an anchor rod for fixing a vegetation blanket. BACKGROUND
[0002] The existing vegetation blanket for slope prevention cannot be well fixed on the complex terrain slope, and thus a vegetation blanket fixing member is needed. As the name implies, the vegetation blanket fixing member is a fixing member for fixing the vegetation blanket on the slope. The vegetation blanket fixing member in the prior art generally uses steel as the main raw material. After the vegetation blanket fixing member is fixed on the slope, the vegetation blanket fixing member is directly inserted into the soil, and the vegetation blanket fixing member has no reinforcing structure. When strong wind or soil collapse occurs, the vegetation blanket still has the problem of poor stability. CONTENT OF THE UTILITY MODEL
[0003] The anchor rod for fixing a vegetation blanket provided by the embodiments of the present application can improve the fixing effect on the vegetation blanket.
[0004] The anchor rod for fixing a vegetation blanket provided by the embodiments of the present application can improve the fixing effect on the vegetation blanket.
[0005] In the scheme, the anchor rod is inserted into the soil more easily by setting a pointed end at the lower end of the anchor rod, and the insertion difficulty of the anchor rod is reduced. By setting the pressing element on the anchor rod, when the anchor rod is inserted into the soil, the anchor rod is in contact with the vegetation blanket through the pressing element, the contact area between the anchor rod and the surface of the vegetation blanket is increased, and the pressing element provides a downward pressure to the vegetation blanket, so that the vegetation blanket can be more stably laid on the slope. In order to improve the installation stability of the anchor rod inserted into the soil, a barb element is arranged on the outer side of the anchor rod. Since the lower end of the barb element is hinged to the anchor rod, the barb element can rotate relative to the anchor rod. In addition, the anchor rod is provided with a blocking portion at the lower end of the barb element, and the blocking portion can limit the rotation angle of the barb element and the anchor rod within an acute angle range. When the anchor rod is inserted into the soil, the barb element is extruded by the soil and rotates upward and closes to the anchor rod, which facilitates the insertion of the anchor rod into the soil. When the anchor rod is inserted into the soil together with the barb element, the anchor rod is subjected to an external force away from the soil side. The barb element is located in the soil and generates a reaction force with the soil. The barb element has a tendency to rotate away from the anchor rod, which increases the resistance to the extraction of the anchor rod, thereby preventing the anchor rod from being extracted from the soil, and the anchor rod is more stably embedded in the soil. That is, when the vegetation blanket is subjected to an external wind force or a disturbance force caused by local collapse of the soil, the anchor rod will not be easily extracted due to the barb element arranged on the outer side of the anchor rod, thereby improving the installation stability of the vegetation blanket and improving the fixing effect of the vegetation blanket.
[0006] In some embodiments, a resilient element is arranged between the barb element and the outer wall of the anchor rod. When the anchor rod is inserted into the soil, the barb element is extruded by the soil and rotates toward the anchor rod, and the resilient element accumulates elastic force.
[0007] In the above technical scheme, the arrangement of the resilient element can increase the force between the barb element and the anchor rod. When the anchor rod is inserted into the soil, the barb element is extruded by the soil and rotates toward the anchor rod. At this time, the resilient element accumulates elastic potential energy. When the anchor rod is subjected to an external force away from the soil side, the barb element generates a reaction force with the soil. At this time, the elastic potential energy is gradually released and has a force to drive the barb element to rotate outward, which facilitates the opening of the barb element, thereby providing greater reaction force to the anchor rod, preventing the anchor rod from being extracted, and better providing anchoring force to the vegetation blanket.
[0008] In some embodiments, the number of barb elements is multiple, and the multiple barb elements are distributed at intervals around the circumference of the anchor rod. The multiple barb elements located on the circumference of the anchor rod form a group of reinforcing units.
[0009] In the above technical scheme, by setting the number of barb elements to multiple, the multiple barb elements are arranged on the outer side of the anchor rod to cooperate together, so that the anti-pulling ability of the circumferential side of the anchor rod is more uniform, and the anchor rod does not have weak points, that is, the anchor rod is not prone to local collapse or tilting, and the fixing effect of the vegetation blanket is good.
[0010] In some embodiments, the number of reinforcement units is set to multiple, and the multiple reinforcement units are distributed at intervals along the length direction of the anchor rod.
[0011] In the above technical solution, by setting the number of reinforcement units to multiple, the multiple reinforcement units work together to provide stronger pull-out resistance to the anchor rod, thereby achieving a better fixing effect on the vegetation blanket.
[0012] In some embodiments, the barb is shaped like a wedge, with an inclined surface facing one side of the anchor rod. From the tip to the clamping member, the distance between the wedge and the anchor rod gradually increases.
[0013] In the above technical solution, by adopting the shape of a wedge-shaped barb with an inclined surface, when the anchor rod is subjected to an external force away from the soil, the barb and the anchor rod are distributed at an acute angle. Under the action of the inclined surface of the barb, the distance between the wedge and the anchor rod gradually increases from the tip to the clamping part. Compared with the barb being a rod-shaped structure, this increases the angle between the barb and the anchor rod. The wedge-shaped block also increases the contact area between the barb and the soil, resulting in a greater reaction force between the barb and the soil, thus improving the fixing effect on the vegetation blanket.
[0014] In some embodiments, the anchor bolt further includes a fastening ring fitted onto the anchor bolt. The fastening ring provides circumferential restraint to multiple barbs in the same set of reinforcement units to hold the multiple barbs against the anchor bolt.
[0015] In the above technical solution, by setting the fastening ring, during the transportation of the anchor bolt, the fastening ring can provide circumferential restraint on multiple barbs in the same group, keeping the multiple barbs close to the anchor bolt, preventing the anchor bolt from spreading outward, improving safety during transportation, avoiding barbs from pricking workers, and also reducing the area occupied by the anchor bolt, which is also conducive to the storage and transportation of the anchor bolt.
[0016] In some embodiments, the clamping element includes a clamping frame and a fastener. The clamping frame has a mounting hole through which it is inserted into the anchor rod, and the fastener is used to clamp the clamping frame to the vegetation blanket.
[0017] In the above technical solution, by setting up a clamping frame, the clamping frame is inserted into the anchor rod through the mounting hole. After the anchor rod is inserted into the soil, the clamping frame is attached to the vegetation blanket. Under the action of the fastener, the clamping frame is pressed against the vegetation blanket, providing a clamping effect to the vegetation blanket, increasing the contact area between the anchor rod and the vegetation blanket, and improving the fixing effect of the vegetation blanket.
[0018] In some embodiments, the fastener is threaded into the anchor bolt.
[0019] In the technical scheme, the fastener is threadedly connected with the anchor rod, the fastener is rotated, the fastener is in contact with the top of the compression frame, the compression frame is provided with a limiting action, the compression frame can be compressed on the vegetation blanket, and the length direction position of the fastener on the anchor rod can be finely adjusted by rotating the fastener, the insertion depth of the anchor rod can be selected according to actual conditions, and the installation flexibility is higher.
[0020] In some embodiments, the shape of the compression frame is any one of a circle, a cross, a field, a back or a square.
[0021] In the technical scheme, the shape of the compression frame can be any one of a circle, a cross, a field, a back or a square, and the flexibility is high, and the actual conditions can be selected.
[0022] In some embodiments, the shape of the tip portion is a cone.
[0023] In the technical scheme, the shape of the tip portion is a cone, the cone-shaped tip portion is easier to be inserted into the soil, the difficulty of inserting the anchor rod into the soil is reduced, and the working difficulty of the worker is reduced.
[0024] Other features and advantages of the present application will be described in detail in the following specific embodiments. BRIEF DESCRIPTION OF DRAWINGS

[0038] In the scheme, the pointed end 11 is arranged at the lower end of the anchor rod 10, the pointed end 11 is more conducive to the insertion of the anchor rod 10 into the soil body, and the insertion difficulty of the anchor rod 10 is reduced. The pressing piece 20 is arranged on the anchor rod 10, after the anchor rod 10 is inserted into the soil body, the anchor rod piece 100 is in close contact with the vegetation blanket 200 through the pressing piece 20, the contact area between the anchor rod piece 100 and the surface of the vegetation blanket 200 is increased, the pressing piece 20 provides a downward pressure to the vegetation blanket 200, and the vegetation blanket 200 can be more stably laid on the slope. In order to improve the installation stability of the anchor rod 10 inserted into the soil body, the barb piece 30 is arranged on the outer side of the anchor rod 10, the lower end of the barb piece 30 is hinged to the anchor rod 10, the barb piece 30 can rotate relative to the anchor rod 10, the anchor rod 10 is provided with a blocking part at the lower end of the barb piece 30, the blocking part can limit the rotation angle between the barb piece 30 and the anchor rod 10 to be within an acute angle range, so that when the anchor rod 10 is inserted into the soil body, the barb piece 30 is extruded by the soil body and rotates upward and closes to the anchor rod 10, which is conducive to the insertion of the anchor rod 10 into the soil body. When the anchor rod 10 is inserted into the soil body together with the barb piece 30, the barb piece 30 is located in the soil body and generates a reaction force with the soil body when the anchor rod 10 is subjected to an external force away from the soil body, the barb piece 30 has a tendency to rotate away from the anchor rod 10, which increases the resistance to the pulling out of the anchor rod 10, thereby preventing the anchor rod 10 from being pulled out of the soil body, so that the anchor rod 10 is more stably embedded in the soil body.

The arrangement of the resilient member 41 can increase the force between the barb 30 and the anchor rod 10. When the anchor rod 10 is inserted into the soil, the barb 30 is pressed by the soil and rotates towards the anchor rod 10, and at this time the resilient member 41 accumulates elastic potential energy. When the anchor rod 10 is subjected to an external force away from the soil, the barb 30 will generate a reaction force with the soil, and at this time the elastic potential energy is gradually released to drive the barb 30 to rotate outward, which helps to open the barb 30, thereby providing greater reaction force to the anchor rod 10, preventing the anchor rod 10 from being pulled out, and better anchoring the vegetation blanket 200.
