Description

Technical Field

[0001] The utility model relates to the technical field of road construction, in particular to a municipal road structure with an anti-settlement function. Background Art

[0002] Common roads are generally built by first compacting the land to form a soil base, and then laying asphalt concrete, cement concrete, stone slabs or cement bricks on the soil base. They have the advantages of flatness, high strength and good durability.

[0003] To prevent the impact of road subsidence caused by rainwater infiltration and erosion of the soil layer, Chinese utility model patent publication number CN218478978U discloses an anti-subsidence municipal road structure, which includes a concrete layer and a soil layer disposed below the concrete layer. Several retaining plates are embedded in the soil layer, with the width of the retaining plates perpendicular to the surface of the soil layer. The retaining plates intersect to form a soil grid to restrict soil flow. The retaining plates have a number of drainage holes on their surfaces for drainage, and the bottom surfaces of the retaining plates are provided with foundation piles for fixing the retaining plates. The foundation piles are set in the ground below the soil layer. This scheme uses several mutually reinforcing soil grids composed of retaining plates to separate the soil layer into several blocks. When rainwater impacts the soil layer, the retaining plates are used to confine the loose soil within the soil grids, making it more difficult for soil to be lost and thus preventing road subsidence.

[0004] However, in this solution, the upper connecting groove on the connecting bar needs to be aligned with the retaining plate in order to be plugged into each other. After the foundation pile is driven into the ground, if the connecting bar is offset during the pile driving process, it will be difficult to rotate the foundation pile that has been driven into the ground, and the retaining plate and the connecting groove cannot be plugged into each other, and the first fixing pin needs to be used for connection, which is time-consuming and labor-intensive.

[0029] The following will clearly and completely describe the technical solutions of the present invention through detailed embodiments and in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Please refer to Figures 1 to 8 This embodiment provides a municipal road structure with anti-settlement functionality, comprising a concrete layer 1 and a soil layer 2. The concrete layer 1 is cast above the soil layer 2, and an anti-settlement structure is provided within the soil layer 2. The anti-settlement structure comprises a grid-shaped connecting frame and a plurality of foundation piles connected to the connecting frame. The cooperation between the connecting frame and the foundation piles enhances the anti-settlement effect. The connecting frame is formed by interconnected mounting rods 8 and connecting rods 9. The foundation pile comprises a pile body 4 and a top plate 3 rotatably connected to the top of the pile body 4. The top plate 3 is provided with mounting slots 10 for engaging and connecting the mounting rods 8 and a locking mechanism for locking the mounting rods 8. After the pile body is driven into the soil layer, the angle of the top plate can be freely rotated and adjusted, allowing the grid-shaped connecting frame to be plugged into all the mounting slots on the top plate without the need to laboriously rotate the pile body. During the connecting frame plugging process, the locking mechanism is automatically triggered to lock the mounting rods on the connecting frame into the mounting slots, thereby enhancing overall stability.

[0031] In some specific implementations, the concrete layer 1 can be cast by using wear-resistant concrete, which is a mixture of cement, fine aggregate, coarse aggregate, quartz sand and water.

[0032] In some specific embodiments, the top plate 3 and the pile body 4 are connected via a rotating mechanism. Figure 4 and Figure 5The rotation mechanism includes an annular cavity 29 and a swivel 31 coaxially distributed with the pile body 4. The annular cavity 29 is disposed above the pile body 4. A channel 28 is connected between the top wall of the annular cavity 29 and the top wall of the pile body 4. The top wall of the swivel 31 is fixedly connected to the bottom wall of the top plate 3 via a connecting ring 30. The swivel 31 is rotatably connected to the inner wall of the annular cavity 29, and the connecting ring 30 is rotatably connected to the inner wall of the channel 28. Thus, under the guiding cooperation of the swivel and the annular cavity, the top plate can be rotated, thereby adjusting the direction of the mounting slot on the top plate so that the mounting rod on the connecting frame can be aligned with the mounting slot for plug-in installation.

[0033] As an improved implementation method, Figure 5 As shown, the outer wall of the rotating ring 31 is rollingly connected with balls 32 that abut against the inner wall of the annular cavity 29. By providing some balls, the friction between the top plate and the pile body during rotation can be reduced, making the linkage smoother and reducing the wear rate of the components.

[0034] In some preferred embodiments, Figure 5 As shown, the top wall, bottom wall, outer wall and inner wall of the rotating ring 31 are all provided with balls 32, so as to reduce friction from multiple directions and improve the smoothness of rotation.

[0035] In some specific embodiments, reference Figures 1 to 3 The mounting rod 8 and the connecting rod 9 are arranged to be perpendicular to each other. The mounting rod 8 and the connecting rod 9 are made of stainless steel, which has the characteristics of strong hardness and strong corrosion resistance.

[0036] In some embodiments, reference Figure 1 、 Figure 2 and Figure 4 The lower end of the pile body 4 is provided with a pile tip 5, which can make the pile body easier to be driven into the soil layer.

[0037] As an improved embodiment, in order to improve the stability of the pile body, the pile body 4 is provided with a clamping mechanism. Figure 1 、 Figure 4 、 Figure 5 and Figure 8The latching mechanism includes a transmission rod 21 and at least one insertion rod 6. A transmission cavity 24 is defined within the pile body 4 for mounting the transmission rod 21. A slider 20, fixedly connected to the top of the transmission rod 21, is slidably coupled to the mounting groove 10. The bottom wall of the slider 20 is connected to the bottom wall of the mounting groove 10 via a third elastic member 22. A wedge-shaped transmission head 23 is fixedly coupled to the lower end of the transmission rod 21. The wedge-shaped transmission head 23 has an inclined surface facing the insertion rod 6. A third channel 25 is defined on the sidewall of the pile body 4, communicating with the transmission cavity 24. The insertion rod 6 is slidably coupled to the third channel 25. One end of the insertion rod 6 extends into the transmission cavity 24 and has an inclined surface facing the wedge-shaped transmission head 23. A connecting piece 26 is defined at the lower portion of the end of the insertion rod 6 near the wedge-shaped transmission head 23. The connecting piece 26 is connected to the inner wall of the transmission cavity 24 via a fourth elastic member 27. For example, the third elastic member 22 and the fourth elastic member 27 are springs. When the connecting frame is plugged into the top plate, as the mounting rod is inserted downward into the mounting groove and overcomes the spring force to push the slider downward, the downward movement of the slider drives the transmission rod and the wedge-shaped transmission head downward. When the wedge-shaped transmission head moves downward, it will use the guiding pushing effect of the inclined surface to push the cutting strip to the outside of the pile body, thereby allowing the cutting strip to be inserted into the soil layer, thereby improving the stability of the pile body.

[0038] In some preferred embodiments, Figure 8 As shown, the inserting rods 6 and the channel three 25 are each provided with two and symmetrically distributed. Thus, when the wedge-shaped transmission head moves downward, the two inserting rods can be driven simultaneously to be inserted into the soil layer in opposite directions, thereby further improving the stability of the pile body.

[0039] In some specific embodiments, such as Figure 8 As shown, the end of the cutting strip 6 away from the wedge-shaped transmission head 23 is provided with a plug 7 distributed outward, so that the cutting strip can be smoothly inserted into the soil layer.

[0040] In some specific embodiments, reference Figures 4 to 7The locking mechanism includes a linkage cavity 11 provided on the top plate 3 and a mounting bar 14 and a force bar 18 movably installed in the linkage cavity 11; a channel 12 slidably connected to the mounting bar 14 is communicated between the upper part of the linkage cavity 11 and the mounting groove 10, and the end of the mounting bar 14 away from the mounting groove 10 is connected to the inner wall of the linkage cavity 11 through an elastic member 15, and the bottom wall of the mounting bar 14 is fixedly connected to a positioning piece 16; a channel 2 13 slidably connected to the force bar 18 is communicated between the lower part of the linkage cavity 11 and the mounting groove 10, and the bottom wall of the force bar 18 is connected to the bottom wall of the linkage cavity 11 through an elastic member 2 19, one end of the force bar 18 extends into the mounting groove 10, and the other end of the force bar 18 is provided with a blocking bar 17 cooperating with the positioning piece 16; the side wall of the mounting rod 8 is provided with a connecting hole 33 plugged into the mounting bar 14. As an example, elastic member 15 and elastic member 2 19 are springs. In the initial state, the force bar extends into the mounting slot and is located below the slider. The blocking bar abuts the positioning piece and limits the positioning piece, and elastic member 1 is in a compressed state. When the connecting frame is plugged into the top plate, as the mounting rod is inserted downward into the mounting slot and overcomes the spring force, the slider moves downward. The downward movement of the slider pushes the force bar downward, overcoming the spring force, thereby causing the blocking bar to move downward and release the positioning piece. The mounting bar, under the elastic force of elastic member 1, moves into the mounting slot, allowing it to be inserted into the connecting hole on the mounting rod, thus locking the mounting rod.

[0041] The implementation process of this utility model:

[0042] In the initial state, if Figure 5 As shown, the stress bar 18 extends into the mounting groove 10 and is located below the slider 20 , the blocking bar 17 abuts against the positioning piece 16 and the blocking bar 17 limits the positioning piece 16 , and the elastic member 15 is in a compressed state.

[0043] refer to Figure 2 When it is necessary to pave the road, first use a pile driver to drive the pile body 4 into the soil layer 2, then rotate and adjust the angle of each top plate 3 so that the installation groove 10 is aligned with the installation rod 8, and then insert the installation rod 8 into the installation groove 10. In the process of plugging the installation rod 8 into the installation groove 10 on the top plate 3, as the installation rod 8 is inserted downward into the installation groove 10 and overcomes the spring force to push the slider 20 downward, on the one hand, as Figure 8 As shown, the slider 20 moves downward, driving the transmission rod 21 and the wedge-shaped transmission head 23 to move downward. When the wedge-shaped transmission head 23 moves downward, it will use the guiding and pushing effect of the inclined surface to push the cutting 6 to the outside of the pile body 4, so that the cutting 6 is inserted into the soil layer 2, thereby improving the stability of the pile body. On the other hand, Figure 5As shown, the downward movement of the slider 20 will also push the force-bearing bar 18 to overcome the spring force and move downward, thereby causing the blocking bar 17 to move downward and release the limit on the positioning piece 16. The mounting bar 14 moves into the mounting groove 10 under the elastic force of the elastic member 15, so that the mounting bar 14 can be inserted into the connecting hole 33 on the mounting rod 8 to complete the locking of the mounting rod.

[0044] Finally, if Figure 1 As shown, concrete is poured on the soil layer 2 to form a concrete layer 1.

[0045] In this way, after the pile body is driven into the soil layer, the angle of the top plate can be freely rotated to adjust the angle, so that the grid-shaped connecting frame can be plugged into the installation slots on all the top plates without the need to laboriously rotate the pile body. In the process of plugging the connecting frame, the installation strip can be automatically inserted into the connecting hole to complete the connection and lock the installation rod without the aid of other external connecting parts. It is convenient and quick, and the insertion strip is automatically inserted into the soil layer, thereby enhancing the stability of the structure and further improving the anti-subsidence effect.

Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by persons skilled in the art without departing from the spirit and technical concepts disclosed in this utility model shall be covered by the claims of this utility model.

[0047] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
