[0024] The technical solution in the embodiment of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows:

[0025] Embodiment 1:

[0026] This embodiment introduces a specific structure of a deep cement mixing pile reinforcement structure. Figure 1-Figure 3 As shown, it includes an inner reinforcement plate 2 arranged on the reinforcement plate 2 and a cement mixing pile body 1, and a soil layer body 3 is arranged outside the cement mixing pile body 1;

[0027] Before the cement mixing pile body 1 is buried in the soil layer 3, obstacles are removed and pits are filled in accordance with the existing ground processing method, and then the cement mixing pile body 1 is processed in the soil layer 3, and one end of the cement mixing pile body 1 is exposed from the top of the soil layer 3, and the reinforcement plate 2 is sleeved on the outside of the cement mixing pile body 1 so that its inner wall fits with the outer wall of the cement mixing pile body 1. After the reinforcement plate 2 is knocked into the soil layer 3, the reinforcement plate 2 can be buried in the soil layer 3 in combination with the cement mixing pile body 1;

[0028] Secondly, in order to guide the reinforcement plate 2 to be buried inside the soil layer 3 and reduce the burying resistance of the soil layer 3, as shown in FIG. Figure 3 As shown, a guide ring 10 is integrally formed at the center of the bottom of the reinforcement plate 2. By utilizing the tip of the bottom of the guide ring 10, when the reinforcement plate 2 is penetrated into the soil layer 3, the resistance is smaller. When the reinforcement plate 2 is hammered and buried, the soil can be discharged to the surroundings with the help of the guide ring 10, and finally the guide ring 10 forms a positioning area 5 on the top of the cement mixing pile body 1;

[0029] At the same time, when the guide ring 10 is completely buried in the soil layer 3, the struck reinforcement plate 2 can continue to be buried in the soil layer 3, and finally the reinforcement plate 2 forms a support area 4 on the top of the soil layer 3. At this time, the interior of the support area 4 is connected to the interior of the positioning area 5;

[0030] Furthermore, in order to further improve the structural strength of the reinforcement plate 2, as Figure 3 As shown, a support ring 8 is integrally formed at the center of the top of the reinforcement plate 2. After the inner walls of the guide ring 10 and the support ring 8 are fitted with the outer wall of the cement mixing pile body 1, the reinforcement plate 2, the support ring 8 and the guide ring 10 can be used to form support around the cement mixing pile body 1.

[0031] In some examples, a plurality of overflow notches 7 are processed inside the reinforcement plate 2. By making the plurality of overflow notches 7 equally spaced around the center of the reinforcement plate 2, the plurality of overflow notches 7 connect the spaces at the top and bottom of the reinforcement plate 2, so that the soil that cannot be compacted can be squeezed out from the overflow notches 7 during the process of the guide ring 10 and the reinforcement plate 2 discharging soil to the surrounding areas.

[0032] At the same time, because the cross-sections of the multiple overflow grooves 7 are all isosceles trapezoids, and the narrow ends of the overflow grooves 7 are facing the bottom of the reinforcement plate 2, after the soil on the soil layer 3 is squeezed out from the overflow grooves 7, it can be connected with the soil at the bottom of the reinforcement plate 2 with the help of the soil inside the overflow grooves 7, thereby increasing the resistance of the reinforcement plate 2 to move toward the top outside the cement mixing pile body 1, thereby ensuring the effect of the reinforcement plate 2 supporting the cement mixing pile body 1 inside the soil layer 3.

[0033] By adopting the above technical solution:

[0034] The above-mentioned design is to provide a reinforcement plate 2 with a guide ring 10 on the bottom outside the cement mixing pile body 1. When the cement mixing pile body 1 is formed inside the soil layer 3 and the reinforcement plate 2 is sleeved on the outside of one end of the cement mixing pile body 1 exposed from the top of the soil layer 3, the guide ring 10 and the reinforcement plate 2 can be buried in the soil layer 3 by knocking, forming a positioning area 5 and a support area 4 respectively. The soil that cannot be compacted during the burial of the guide ring 10 and the reinforcement plate 2 is discharged from the bottom of the overflow groove 7 to the top. The soil inside the overflow groove 7 is connected with the soil at the bottom of the reinforcement plate 2, thereby increasing the resistance of the reinforcement plate 2 to the movement of the outside of the cement mixing pile body 1 toward the top, thereby ensuring the effect of the reinforcement plate 2 supporting the cement mixing pile body 1 inside the soil layer 3. At this time, only one end of the cement mixing pile body 1 at the top of the soil layer 3 is raised, which will not affect the subsequent construction work of the building. By laying soil on the top of the reinforcement plate 2, the top of the soil layer 3 will not be concave.

[0035] Embodiment 2:

[0036] Based on Example 1, this example introduces the specific structure of the reinforcement plate 2. The top of the reinforcement plate 2 is processed with multiple reinforcement ribs 6, and the tops of the multiple reinforcement ribs 6 are processed with the same impact ring 9.

[0037] Among them, one end of the plurality of reinforcing ribs 6 is welded and fixed to the outer wall of the support ring 8, and the plurality of reinforcing ribs 6 and the plurality of overflow notches 7 are arranged alternately. By utilizing the plurality of reinforcing ribs 6, the connection strength between the support ring 8 and the reinforcing plate 2 can be enhanced, and the ability of the reinforcing plate 2 to resist deformation around can be increased;

[0038] Secondly, by making the top of the impact ring 9 flush with the top of the support ring 8, a striking point can be provided for the embedding work of the reinforcement plate 2 and the guide ring 10, and the end face of the impact ring 9 can be used to provide a reference for the embedding degree of the reinforcement plate 2.

[0039] By adopting the above technical solution:

[0040] The above-mentioned design processes multiple reinforcing ribs 6 between the top of the reinforcement plate 2 and the outer wall of the support ring 8, and processes the same impact ring 9 on the top of the multiple reinforcing ribs 6. During the process of burying the reinforcement plate 2 and the guide ring 10, the impact ring 9 can be used to provide a knocking point, and the multiple reinforcing ribs 6 can enhance the connection strength between the support ring 8 and the reinforcement plate 2, and increase the ability of the reinforcement plate 2 to resist deformation around it, thereby ensuring the structural strength of the reinforcement plate 2.

[0041] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
