[0022] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, the gravel pile reinforcement device of the utility model comprises a reinforcement sleeve 1 with openings at both ends, a pile body filling through hole 2 which passes through from top to bottom is arranged in the middle of the reinforcement sleeve 1, and grid holes 3 distributed in a grid are arranged on the side wall of the reinforcement sleeve 1, and the grid holes 3 are connected with the pile body filling through hole 2.

[0024] The upper and lower ends of the reinforcement sleeve 1 are both opened, and the openings are connected to the pile body filling through hole 2, so that the pile body can be set in the pile body filling through hole 2. The grille holes 3 can ensure that the gravel and sand in the pile body filling through hole 2 are vibrated and compacted, and the air and moisture in the pile body can be discharged. In order to ensure the use effect of the grille holes 3, the cross-sectional shape is preferably circular, and the diameter is smaller than the diameter of the gravel to prevent the gravel from leaking along the grille holes 3.

[0025] The shape of the pile body is usually cylindrical, so the reinforcement sleeve 1 is cylindrical, and the pile body filling through hole 2 is also cylindrical. In order to ensure the use effect of the reinforcement sleeve, the material of the reinforcement sleeve 1 is preferably fiberboard, which has strong tensile strength, corrosion resistance, aging resistance and other characteristics, and is particularly suitable for use in soft sandwich roadbed.

[0026] For some gravel piles with higher height, the height of the pile body is also higher, and multiple reinforcement sleeves 1 need to be provided, and all the reinforcement sleeves 1 are connected together in sequence from bottom to top, such as Figure 1 As shown, the center lines of the pile filling through holes 2 in all the reinforcement sleeves 1 are on the same vertical straight line, ensuring the vertical verticality of the pile body.

[0027] The gravel pile is formed by vibrating and compacting gravel and sand. When the pile is high, the pile is constructed from bottom to top in sections, that is, after the construction of the lower section is completed, the upper section is constructed until all the piles are completed. In order to ensure the construction quality of the pile, reduce the possibility of deviation between the upper and lower sections, and ensure the verticality of the pile, Figure 1 , Figure 2 and Figure 3As shown, the utility model is provided with an anti-deviation positioning connector 4 on the outer wall of the reinforcement sleeve 1, the upper end of the anti-deviation positioning connector 4 extends to the top of the reinforcement sleeve 1, and the lower end of the anti-deviation positioning connector 4 extends to the bottom of the reinforcement sleeve 1, and the upper and lower adjacent reinforcement sleeves 1 are connected by the anti-deviation positioning connector 4. The anti-deviation positioning connector mainly plays a positioning connection role, so that the upper and lower adjacent reinforcement sleeves 1 do not deviate in the height direction, thereby reducing the possibility of the pile body in the upper and lower adjacent reinforcement sleeves 1 deviating. During the construction of gravel piles, first install the relatively lower reinforcement sleeve 1 in the gravel pile hole, then fill the reinforcement sleeve 1 with gravel and sand, and vibrate the gravel and sand to form the pile body after vibration compaction. The upper end of the pile body is flush with the upper end of the corresponding reinforcement sleeve 1, and then install the anti-deviation positioning connector 4 relatively on the upper side on the anti-deviation positioning connector 4 of the lower reinforcement sleeve 1 to achieve the connection between the upper and lower adjacent reinforcement sleeves 1, and finally fill the connecting section of the upper and lower adjacent reinforcement sleeves 1 and the relatively upper reinforcement sleeve 1 with gravel and sand, and vibrate the gravel and sand to form the pile body after vibration compaction, and so on, until the construction of the gravel pile is completed. Since the anti-deviation positioning connector is located on the outside of the reinforcement sleeve 1, it can also effectively increase the strength of the reinforcement sleeve 1.

[0028] In order to improve the use effect of the anti-deviation positioning connector 4, a preferred structure of the anti-deviation positioning connector 4 of the utility model is: Figure 2 , Figure 3 As shown, the anti-deviated positioning connector 4 includes at least three connecting ribs 5, all of which are evenly distributed on the outer wall of the reinforcement sleeve 1. A connecting sleeve 6 is provided at the upper end of the connecting rib 5, and the connecting ribs 5 of the upper and lower adjacent reinforcement sleeves 1 are connected together through the connecting sleeve 6. A connecting hole is provided in the middle of the connecting sleeve 6, and the connecting rib 5 relatively located at the lower side is provided in the lower half of the connecting hole, and the connecting rib 5 relatively located at the upper side is provided in the upper half of the connecting hole. The connecting sleeve 6 facilitates connecting the connecting ribs 5 of the upper and lower adjacent reinforcement sleeves 1 together. In order to ensure the use effect of the connecting rib 5, the connecting rib 5 is preferably a fiber reinforced steel bar.

[0029] The gravel pile comprises a pile body and the gravel pile reinforcement device mentioned above, wherein the pile body is matched and arranged in the pile body filling through hole 2 of the reinforcement sleeve 1 .

[0030] The reinforcement sleeve 1 wraps the pile body, reducing the possibility of lateral deformation of the pile body and loosening of gravel and sand, effectively improving the bearing capacity of the pile body, increasing the strength of the gravel pile, and further enhancing the reinforcement effect on the soft interlayer roadbed.

[0031] During the construction of the gravel pile of the utility model, firstly, the reinforcement sleeve 1 relatively located at the lower side is installed in the gravel pile hole, and then gravel and sand are filled into the reinforcement sleeve 1, and the gravel and sand are vibrated to form the pile body after vibration and compaction, and the upper end of the pile body is flush with the upper end of the corresponding reinforcement sleeve 1, and then the anti-deviation positioning connector 4 relatively located at the upper side is installed on the anti-deviation positioning connector 4 of the reinforcement sleeve 1 at the lower side to achieve the connection of the upper and lower adjacent reinforcement sleeves 1, and finally, gravel and sand are filled into the connecting sections of the upper and lower adjacent reinforcement sleeves 1 and the reinforcement sleeve 1 relatively located at the upper side, and the gravel and sand are vibrated to form the pile body after vibration and compaction, and so on, until the construction of the gravel pile is completed.

[0032] In order to further improve the bearing capacity of the gravel pile, the utility model is further provided with a plurality of load buffer pads 7, all of which are sequentially arranged in the pile body from bottom to top, and the load buffer pads 7 are preferably made of carbon fiber cloth.
