Description

TECHNICAL FIELD

[0001] The utility model relates to the field of highway protection, especially to a mountainous area along river highway roadbed protection structure. BACKGROUND

[0002] The importance of mountainous area along river highway roadbed protection lies not only in ensuring the stability and safety of the highway, but also in protecting the ecological environment, promoting economic development, and responding to the challenges brought by climate change. Through scientific and reasonable protection measures, the damage of natural disasters to the highway can be effectively reduced, the service life of the highway is prolonged, and strong support is provided for mountainous area traffic and economic development.

[0003] In the prior art, although a certain land protection effect can be achieved on both sides of the roadbed during use, the existing roadbed protection device on both sides lacks convenient disassembly and poor anti-loosening effect. In view of this, the mountainous area along river highway roadbed protection structure is proposed to solve the above problems. UTILITY MODEL CONTENTS

[0004] The utility model aims at the problems in the background art and provides a mountainous area along river highway roadbed protection structure.

[0005] The technical scheme of the utility model is a mountainous area along river highway roadbed protection structure, which comprises a mounting column, a through hole, a rivet and a fence, the inside lower half of the mounting column is fixed with through holes arranged in a ring array, the inside of the through hole is provided with a limiting ring with an elastic mechanism, the inside of the limiting ring is rotatably installed with a rivet, the upper end of the mounting column is provided with a mounting groove, the inside of the mounting groove is inserted with a plug rod, the upper end of the plug rod is fixed with a fence, and the distance between the fence cross frame and the two mounting columns is controlled.

[0006] When the device is used, the corresponding positions on both sides of the roadbed are found, the mounting column is vertically inserted, the mounting column is embedded into the baffle and contacts with the road surface, then the distance between the two mounting columns is controlled, the fence is inserted into the mounting groove at the upper end of the two mounting columns, the rubber plug moves downward and is hammered downward by a hammer, the rubber plug contacts with the eaves of the rivet cap, the rivet is expanded and inserted into the inside of the road surface at the lower end, a secondary fixed position is formed, and the fence will not rebound under the friction of the rubber plug, manual force is needed to remove it, the fence moves downward, the grid also inserts into the road surface at the lower end, and a line area formed between the fence and the mounting column has high protection effect, which can reduce the loosening of the roadbed surface and increase the protection effect of the mountainous area along river highway roadbed, and has high practicability.

[0007] Preferably, a rubber stopper is fixed at the lower end of the insertion rod. The diameter of the rubber stopper is slightly larger than the inner diameter of the mounting groove. The lower surface of the rubber stopper is designed with an arc shape. By utilizing the interference design of the rubber stopper, the rubber stopper can be pressed down to the maximum stroke by the fixing rivet with the help of friction, so that it enters the roadbed and increases the embedding stability of the mounting post.

[0008] Preferably, a spring is fixed inside the through hole, and the upper end of the spring is fixedly connected to the lower end of the limiting ring.

[0009] Preferably, the inner wall of the limiting ring is provided with an internal thread, which is rotatably connected to the rivet. The upper end of the rivet is provided with a cap, which fits against the upper surface of the limiting ring. The upper surface of the cap is arc-shaped. The internal thread design allows the rivet to be tightly connected to the limiting ring by rotation, ensuring that the rivet is more stable when inserted into the road surface.

[0010] Preferably, when the spring is in its natural state, the lower surface of the rivet is flush with the lower end of the through hole. This design, where the lower surface of the rivet is flush with the lower end of the through hole when the spring is in its natural state, ensures that the rivet can be inserted smoothly into the road surface, avoiding the protruding part of the rivet front end, which would affect the smooth insertion of the mounting post.

[0011] Preferably, the lower end of the mounting column is fixed with a conical head, and the upper end of the mounting column is provided with a corresponding groove on the opposite side. The groove design allows the fence to be inserted as close to the ground as possible, ensuring that the grid is inserted to the appropriate depth.

[0012] Preferably, handles are fixed to the outer walls on both sides of the mounting column, and baffles are fixed to the outer wall of the lower half of the mounting column. The handles are designed to facilitate operation by construction personnel during installation and disassembly.

[0013] Preferably, the lower end of the enclosure is fixed with a grid arranged in a linear array. The lower end of the grid is tapered. The linear array arrangement of the grid can effectively increase the contact area between the enclosure and the roadbed, further improve the protective effect, and reduce the movement of soil at the lower end of the ground.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] I. This utility model utilizes rivets with a downward-sloping design inside the mounting column. After the enclosure is inserted into the mounting column, the rivets can expand outward in a conical shape, increasing the stability of the mounting column. Furthermore, with the spring design, the rivets can spring back when the mounting column is removed, enabling the quick removal of the mounting column.

[0016] Second, based on the first beneficial effect, after the fence is inserted into the installation column, the linear array of grids at the lower end of the fence will insert into the ground, so that the straight area between the installation columns forms a good anti-soil flow effect, achieving good protection and increasing the service life of the road surface.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0028] Example 1

[0029] Please see Figures 1-4 As shown, this embodiment is a roadbed protection structure for a riverside highway in mountainous areas, including mounting posts 1, through holes 4, rivets 15 and enclosures 8. The inner wall of the lower half of the mounting post 1 is fixed with through holes 4 arranged in a ring array. The through holes 4 are provided with a limiting ring 12 with an elastic mechanism. The rivets 15 are rotatably installed inside the limiting ring 12. The upper end of the mounting post 1 is provided with a mounting groove 10. A rod 7 is inserted into the mounting groove 10. The upper end of the rod 7 is fixed with enclosures 8. Enclosures 8 are used to frame the distance between two mounting posts 1.

[0030] When using this device, locate the corresponding positions on both sides of the roadbed, vertically insert the mounting post 1, and embed it downwards until the baffle 2 contacts the road surface. Then, control the distance between each pair of mounting posts 1, and insert the enclosure 8 into the mounting groove 10 at the upper end of the two mounting posts 1. The rubber plug 6 moves downwards and is hammered downwards. The rubber plug 6 contacts the cap 16 of the rivet 15, and the rivet 15 extends and inserts into the road surface at the lower end, forming a secondary fixing position. Under the friction of the rubber plug 6, the enclosure 8 will not spring back and can only be removed by manual force. At the same time as the enclosure 8 moves downwards, the grille 9 will also insert into the road surface at the lower end. The area formed by the enclosure 9 and the mounting post 1 has a highly efficient protective effect, which can reduce the loosening of the roadbed surface and increase the protection effect of the roadbed of mountainous riverside highways. It has high practicality.

[0031] Example 2

[0032] Please see Figures 1-4 As shown, this embodiment, based on embodiment 1, further includes: a rubber stopper 6 fixed at the lower end of the insertion rod 7. The diameter of the rubber stopper 6 is slightly larger than the inner diameter of the mounting groove 10. The lower surface of the rubber stopper 6 is arc-shaped. By utilizing the interference design of the rubber stopper 6, the rubber stopper 6 can be pressed down to the maximum stroke by the friction force of the fixing rivet 15, so that it enters the roadbed and increases the embedding stability of the mounting post 1.

[0033] A spring 14 is fixed inside the through hole 4. The upper end of the spring 14 is fixedly connected to the lower end of the limiting ring 12. When the enclosure 8 is removed, the rubber plug 6 is pulled out of the mounting groove 10. Under the action of the spring 14, the rivet 15 can be retracted into the through hole 4, which facilitates the quick removal of the mounting column 1.

[0034] The inner wall of the limiting ring 12 is provided with an internal thread 13, which is rotatably connected to the rivet 15. The upper end of the rivet 15 is provided with a cap 16, which fits against the upper surface of the limiting ring 12. The upper surface of the cap 16 is arc-shaped. The design of the internal thread 13 allows the rivet 15 to be tightly connected to the limiting ring 12 by rotation, ensuring that the rivet 15 is more stable when inserted into the road surface. The arc-shaped design of the upper surface of the cap 16 can better contact the rubber stopper 6, ensuring that the rivet 15 can smoothly extend downward into the road surface when hammered, further improving the stability and protective effect of the device.

[0035] When the spring 14 is in its natural state, the lower surface of the rivet 15 is flush with the lower end of the through hole 4. This design ensures that the lower surface of the rivet 15 is flush with the lower end of the through hole 4 when the spring 14 is in its natural state, so that the rivet 15 can be inserted smoothly into the road surface, avoiding the front end of the rivet 15 from protruding and affecting the smooth insertion of the mounting post 1.

[0036] The lower end of the mounting column 1 is fixed with a conical head 3, and the upper end of the mounting column 1 is provided with a corresponding groove 11 on the opposite side. The design of the groove 11 makes it easy for the enclosure 8 to be inserted as close to the ground as possible, so that the insertion depth of the grille 9 is appropriate.

[0037] Handles 5 are fixed to the outer walls on both sides of the mounting post 1, and baffles 2 are fixed to the outer wall of the lower half of the mounting post 1. The design of the handles 5 makes it convenient for construction personnel to operate during installation and disassembly, thereby improving construction efficiency. The design of the baffles 2 can effectively prevent the mounting post 1 from sinking excessively when inserted into the roadbed, ensuring that the installation depth of the mounting post 1 is consistent, and further improving the stability and protection effect of the device.

[0038] The lower end of the enclosure 8 is fixed with a grid 9 arranged in a linear array. The lower end of the grid 9 is tapered. The linear array of the grid 9 can effectively increase the contact area between the enclosure 8 and the roadbed, further improve the protection effect, and reduce the movement of soil at the bottom of the ground. The tapered design of the lower end of the grid 9 makes it easier to insert the grid 9 into the roadbed, reduces the insertion resistance, and ensures that the grid 9 can be smoothly inserted into the roadbed and form a protective area in a straight line with the installation post 1.

[0039] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
