However, when the pile foundation is installed, the above technical solution only fixes the pile foundation and the ground to each other by a simple plug-in fit. If the soil on which the pile foundation is installed is relatively soft, the pile foundation's grip on the ground will be reduced, affecting the stability of the pile foundation.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0006] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a high-stability pile foundation, which solves the problem that when the pile foundation and the ground are fixed to each other, if the soil on which the pile foundation is to be installed is relatively soft, the grip of the pile foundation on the ground will be reduced, affecting the stability of the pile foundation.

[0008] By adopting the above technical scheme, when the pile basic body needs to be installed, the pile basic body is inserted into the reserved hole, and then the mobile pile is placed above the placement groove, and then pressure is applied to the mobile pile to drive the mobile pile to move downward along the placement groove and contact with a plurality of fixed rods. At this time, pressure is continued to be applied to the mobile pile. Since the bottom of the mobile pile is arranged obliquely, when the inclined surface of the bottom of the mobile pile and the fixed rod contact each other, the fixed rod will be affected and move toward the outside along the through hole, and drive a plurality of fixed rods to be inserted into the ground outside, and then the mobile pile and the pile basic body are fixed to each other through the clamping assembly, so as to achieve the effect of installing the pile basic body. By setting a plurality of fixed rods, the contact surface of the pile basic body in the ground can be increased, and at the same time, the gripping force between the pile basic body and the ground is increased, thereby improving the stability of the pile basic body. At the same time, by setting the fixing assembly, the separation between the fixed rod and the through hole can be avoided, thereby improving the stability of the fixed rod.

[0009] The utility model is further configured as follows: the fixing assembly includes a plurality of support plates rotatably connected to the side walls of the placement groove, a flexible strip is fixedly connected between two adjacent support plates, and when the flexible strip is in a natural state, the plurality of support plates are horizontally arranged with each other and contact with the fixing rod.

[0010] By adopting the above technical solution, when the fixing rod is located in the pile basic body, the setting of the plurality of flexible strips can drive the plurality of support plates to maintain a horizontal state, and at the same time, the plurality of fixing rods are lifted by the support plates, so as to achieve the effect of supporting the fixing rod.

When the mobile pile is inserted into the placement groove and contacts with the plurality of fixing rods, pressure is applied to the plurality of fixing rods, and at this time, the plurality of fixing rods are affected by the pressure and move outward along the through hole, and then continue to apply pressure to the mobile pile, and at this time, the plurality of support plates begin to rotate under the influence of the pressure, and at the same time, the flexible strips are driven to begin to deform, and at this time, the fixing rod is affected by the mobile pile and moves toward the outside along the through hole, so as to achieve the effect of supporting the fixing rod when the fixing rod is located in the placement groove, avoiding the separation of the fixing rod and the through hole, and at the same time, the setting of the flexible strips can drive the plurality of support plates to always abut against the mobile pile, and further improve the fixing effect of the mobile pile in the placement groove.

[0011] The utility model is further configured as follows: the clamping assembly includes a connecting rod fixedly connected to the bottom of the placement groove, the bottom of the movable pile is provided with a sliding groove for the connecting rod to be inserted, the side wall of the sliding groove is provided with a plurality of grooves, and limiting blocks are slidably connected in the plurality of grooves, the limiting blocks and the grooves are connected by a spring, the side wall of the connecting rod is provided with an annular groove, and when the spring is in a natural state, the limiting block and the annular groove are clamped with each other.

At this time, the spring located in the groove begins to deform and compress under the influence of the pressure of the limiting block. When the annular groove on the connecting rod moves to the same horizontal state as the limiting block, the spring loses its restriction and begins to deform and recover, and at the same time drives the limiting block into the annular groove and engages with the annular groove, thereby achieving the effect of fixing the mobile pile and the placement groove to each other.

[0013] The utility model is further configured as follows: a side of a plurality of the fixing rods away from the through hole is fixedly connected to a limiting plate, and the limiting plate is slidably connected to the supporting plate.

[0014] By adopting the above technical solution, the moving position of the fixing rod can be limited, thereby preventing the fixing rod from being separated from the through hole when moving outward.

[0033] A high stability pile foundation, such as Figure 1-Figure 5As shown, it comprises a pile basic body 1 and a pile support platform 2 connected to each other, a placement groove 3 is provided on the pile basic body 1, a movable pile 4 is slidably connected in the placement groove 3, the side wall of the movable pile 4 and the placement groove 3 fit each other, a plurality of through holes 5 are provided on the side wall of the pile basic body 1, a plurality of fixing rods 6 are slidably connected to the side walls of the through holes 5, a fixing component for preventing the fixing rods 6 and the through holes 5 from being separated from each other and a clamping component for fixing the position of the movable pile 4 are provided in the placement groove 3, the bottom of the movable pile 4 is obliquely arranged, when the pile basic body 1 needs to be installed, the pile basic body 1 is inserted into the reserved hole, and then the movable pile 4 is placed above the placement groove 3, and then pressure is applied to the movable pile 4 to drive the movable pile 4 to move downward along the placement groove 3 and to engage with a plurality of fixing rods 6. The fixed rods 6 are in contact with each other, and pressure continues to be applied to the movable pile 4. Since the bottom of the movable pile 4 is arranged obliquely, when the inclined surface at the bottom of the movable pile 4 and the fixed rod 6 are in contact with each other, the fixed rod 6 will be affected and move toward the outside along the through hole 5, and drive a number of fixed rods 6 to be inserted into the ground outside, and then the movable pile 4 and the pile basic body 1 are fixed to each other through the clamping assembly, so as to achieve the effect of installing the pile basic body 1. By setting a number of fixed rods 6, the contact surface of the pile basic body 1 in the ground can be increased, and at the same time, the gripping force between the pile basic body 1 and the ground is increased, thereby improving the stability of the pile basic body 1. At the same time, by setting the fixing assembly, the separation between the fixed rod 6 and the through hole 5 can be avoided, thereby improving the stability of the fixed rod 6.

[0034] like Figure 1-Figure 5As shown, the fixing assembly includes a plurality of support plates 7 rotatably connected to the side walls of the placement groove 3, and a flexible strip 8 is fixedly connected between two adjacent support plates 7. When the flexible strip 8 is in a natural state, the plurality of support plates 7 are horizontally arranged with each other and contact with the fixing rod 6. When the fixing rod 6 is located in the pile basic body 1, the plurality of flexible strips 8 are arranged to drive the plurality of support plates 7 to maintain a horizontal state, and at the same time, the plurality of fixing rods 6 are lifted up by the support plates 7, so as to achieve the effect of supporting the fixing rod 6. When the fixing rod 6 and the support plates 7 contact each other, the fixing rod 6 is affected by the support plates 7, so that the position of the fixing rod 6 cannot be offset downward, so as to achieve the effect of limiting the moving position of the plurality of fixing rods 6, avoiding the separation of the fixing rod 6 and the through hole 5. When the movable pile 4 is inserted into the placement groove 3 and contacts with the plurality of fixing rods 6, pressure is applied to the plurality of fixing rods 6. At this time, the plurality of fixing rods 6 are affected by the pressure and move outward along the through hole 5, and then continue to apply pressure to the movable pile 4. When the fixing rod 6 is in the placement groove 3, the fixing rod 6 can be supported by the supporting plate 7 to prevent the fixing rod 6 and the through hole 5 from being separated from each other. At the same time, the setting of the flexible strip 8 can drive the supporting plates 7 to always contact with the moving pile 4, thereby further improving the fixing effect of the moving pile 4 in the placement groove 3. The bottom of the supporting plates 7 is fixedly connected with a fixing block 17, and the side wall of the pile basic body 1 is provided with a through groove 18 for the fixing block 17 to be rotatably connected. When the supporting plate 7 and the side wall of the placement groove 3 contact each other, the fixing block 17 passes through the through groove 18 to the outside. When the moving pile 4 drives the supporting plate 7 to move, the supporting plate 7 will drive the fixing block 17 to rotate in the direction of the through groove 18 and insert the fixing block 17 into the ground, thereby further improving the fixing effect of the pile basic body 1 on the ground.

[0035] like Figure 1-Figure 5As shown, the clamping assembly includes a connecting rod 9 fixedly connected to the bottom of the placement groove 3, a sliding groove 10 for inserting the connecting rod 9 is provided at the bottom of the movable pile 4, a plurality of grooves 11 are provided on the side wall of the sliding groove 10, and a plurality of limiting blocks 12 are slidably connected in the grooves 11. The limiting blocks 12 and the grooves 11 are connected by springs 13. An annular groove 14 is provided on the side wall of the connecting rod 9. When the spring 13 is in a natural state, the limiting block 12 and the annular groove 14 are clamped with each other. After the movable pile 4 drives the fixed rod 6 to move outward, the movable pile 4 continues to be driven downward, and at the same time, the connecting rod 9 is driven to be inserted into the sliding groove 10 at the bottom of the movable pile 4, and the connecting rod 9 and the limiting block 12 are driven to contact each other, and then the movable pile 4 is moved. Applying pressure drives the movable pile 4 to continue to move downward, and drives the limiting block 12 to move toward the inside of the groove 11. At this time, the spring 13 located in the groove 11 begins to deform and compress under the influence of the pressure of the limiting block 12. When the annular groove 14 on the connecting rod 9 moves to the same horizontal state as the limiting block 12, the spring 13 loses its restriction and begins to deform and recover, and drives the limiting block 12 to enter the annular groove 14 and engage with the annular groove 14, thereby achieving the effect of fixing the movable pile 4 and the placement groove 3 to each other. The cross-section of the connecting rod 9 is rectangular. After the connecting rod 9 is inserted into the slide groove 10, it can drive the movable pile 4 to rotate, thereby improving the fixing effect between the movable pile 4 and the placement groove 3.

[0036] like Figure 1-Figure 5 As shown, a plurality of fixing rods 6 are fixedly connected to a limiting plate 15 on one side away from the through hole 5, and the limiting plate 15 is slidably connected to the supporting plate 7, which can limit the moving position of the fixing rod 6 and prevent the fixing rod 6 from being separated from the through hole 5 when moving outward. A film 16 is fixedly connected to the side wall of the pile basic body 1, and the film 16 covers a plurality of through holes 5. When the pile basic body 1 is placed in the reserved hole, the film 16 can be set to prevent the through hole 5 from being blocked by mud on the ground. At the same time, when the fixing rod 6 moves outward, the film 16 can be broken by the fixing rod 6, so as to achieve the effect of preventing the through hole 5 from being blocked while the fixing rod 6 can move outward normally, which is convenient for the fixing rod 6 to move. The side wall of the film 16 extends toward the through groove 18 and covers the through groove 18, which can prevent the through groove 18 from being blocked by mud on the ground, and facilitates the insertion of the fixing block 17 into the ground.

[0037] The utility model is used normally as follows: when the pile basic body 1 needs to be installed, the pile basic body 1 is inserted into the reserved hole, and then the movable pile 4 is placed above the placement groove 3, and then pressure is applied to the movable pile 4 to drive the movable pile 4 to move downward along the placement groove 3 and contact with a plurality of fixed rods 6. At this time, pressure is continued to be applied to the movable pile 4 to drive a plurality of fixed rods 6 to move toward the outside along the through hole 5, and drive a plurality of fixed rods 6 to be inserted into the ground outside, and then the movable pile 4 is continued to be driven to move downward, and at the same time, the connecting rod 9 is driven to be inserted into the slide groove 10 at the bottom of the movable pile 4, and the connecting rod 9 and the limiting block 12 are driven to contact each other, and then pressure is applied to the movable pile 4 to drive the movable pile 4 to continue to move downward, and the limiting block 12 is driven to the groove 11 The pile 4 and the pile body 1 are moved inwardly, and the spring 13 in the groove 11 begins to deform and compress under the influence of the pressure of the limiting block 12. When the annular groove 14 on the connecting rod 9 moves to the same horizontal state as the limiting block 12, the spring 13 loses its restriction and begins to recover its shape, and drives the limiting block 12 to enter the annular groove 14 and engage with the annular groove 14 to fix the movable pile 4 and the pile basic body 1 to each other, thereby achieving the effect of installing the pile basic body 1. By setting a plurality of fixing rods 6, the contact surface of the pile basic body 1 in the ground can be increased, and the gripping force between the pile basic body 1 and the ground can be increased, thereby improving the stability of the pile basic body 1. At the same time, by setting the fixing assembly, the separation between the fixing rod 6 and the through hole 5 can be avoided, thereby improving the stability of the fixing rod 6.
