This application improves the convenience of connecting the reinforcement piles, thereby increasing the efficiency of construction operations.

[0004] Although the above-mentioned prior art solutions can achieve the relevant beneficial effects through the structure of the prior art, they still have the following defects:

[0005] 1. The reinforced pile is a simple cylindrical structure with a smooth surface. After being inserted into the soft soil foundation, the connection between the outer wall of the reinforced pile and the soil layer is low. After being compressed, the reinforced pile is easy to settle, and the reinforced support capacity is low;

[0006] 2. The connection method between the reinforcement piles is cumbersome and time-consuming. In addition, the reinforcement piles are often distributed in an array. The above connection can only connect the reinforcement piles in the same row, and cannot connect two adjacent rows.

[0007] Regarding the above-mentioned related technologies, the inventor believes that the reinforcement piles are simple cylindrical structures with smooth surfaces. After being inserted into the soft soil foundation, the connectivity between the outer wall of the reinforcement pile and the soil layer is low. The reinforcement piles are prone to settlement after being compressed, and the reinforcement support capacity is low. The connection method between the reinforcement piles is cumbersome and the construction is time-consuming. Moreover, the reinforcement piles are often distributed in an array. The above connection can only connect the reinforcement piles in the same row, and cannot connect the two adjacent rows.

[0008] In view of this, we propose a highway soft soil foundation reinforcement structure. Utility Model Content

Then, the anti-sinking mechanism 3 is controlled from the top of the reinforcement pile 1, so that the anti-sinking mechanism 3 extends from the outer wall of the reinforcement pile 1 and is laterally inserted into the soft soil layer, thereby improving the connection strength between the reinforcement pile 1 and the soft soil layer, thereby improving the bearing capacity. Concrete is poured into the connecting cavity 2 through the pouring hole 5. After the concrete is cured, the strength of the reinforcement pile 1 is increased, and the reinforcement effect is improved. The reinforcement piles 1 between rows are easily connected through the connecting mechanism 4, thereby further improving the anti-sinking effect.

[0037] Reference Figures 1 to 3 The anti-sinking mechanism 3 includes a through slot 31. The circumferential outer wall of the reinforcement pile 1 is provided with a plurality of through slots 31 communicating with the connecting cavity 2. A rotating shaft 32 is rotatably connected between the inner wall of one end of the through slot 31. A plug plate 33 is fixedly sleeved on the rotating shaft 32, and a torsion spring is installed between the top and bottom of the rotating shaft 32 and the through slot 31. A screw 34 is rotatably connected in the connecting cavity 2. A limiting cylinder 35 is threadedly sleeved on the screw 34. The circumferential outer wall of the limiting cylinder 35 movably fits the inner wall of the plurality of plug plates 33. An extrusion block 36 is fixedly installed on the top of the limiting cylinder 35. The extrusion block 36 is a frustum structure, and the small diameter end of the frustum is connected to the limiting cylinder 35. A fixing plate 37 is fixedly installed between the inner wall of the connecting cavity 2 at the top of the extrusion block 36, and a guide rod 38 is fixedly installed on the top of the extrusion block 36. The rod 38 slides through the fixed plate 37. Before the reinforcement pile 1 is inserted into the soft foundation, the screw 34 is rotated to make the limiting cylinder 35 move up, and the extrusion block 36 does not contact the plug plate 33. At this time, the rotating shaft 32 is acted upon by the torsion spring so that the plug plate 33 is accommodated in the connecting cavity 2, and the inner side of the plug plate 33 is attached to the outer wall of the limiting cylinder 35. The outer side of the plug plate 33 is aligned with the outer wall of the circumference of the reinforcement pile 1, thereby facilitating the insertion of the reinforcement pile 1 into the soft foundation. After insertion, the screw 34 is rotated, the limiting cylinder 35 moves downward, and the outer wall of the truncated cone of the extrusion block 36 gradually squeezes the plug plate 33, so that the plug plate 33 is rotated out of the through groove 31 and inserted into the soft soil layer, thereby increasing the vertical connection area of ​​the reinforcement pile 1 with the soil layer, increasing the anti-settling ability of the reinforcement pile 1, and thus improving the bearing capacity reinforcement effect of the foundation.

The knob 7 is rotated and clamped in the countersunk hole 6, and the top of the knob 7 is provided with a cross groove. The thickness of the knob 7 is less than the depth of the countersunk hole 6, so that when the reinforcement pile 1 is inserted into the soft soil foundation, it is convenient to knock the top of the reinforcement pile 1 with a hammer, etc., which facilitates the insertion of the reinforcement pile without touching the knob 7. After insertion, the screw 34 is driven to rotate by the knob 7, so that the inserting plate 33 is inserted into the soil layer.

The operation is fast, and all the reinforcement piles 1 are connected to each other, thereby improving the reinforcement effect.

[0040] Furthermore, after the reinforcement pile 1 is inserted into the soft soil foundation, the top of the foundation is filled with soil, sand and gravel, as in the comparative case.

[0041] Working principle: Before the reinforcement pile 1 is inserted into the soft soil foundation, the screw 34 is rotated to make the limiting cylinder 35 move up, and the extrusion block 36 does not contact the plug plate 33. At this time, the rotating shaft 32 is acted upon by the torsion spring so that the plug plate 33 is accommodated in the connecting cavity 2, and the inner side of the plug plate 33 is attached to the outer wall of the limiting cylinder 35. The outer side of the plug plate 33 is aligned with the outer wall of the circumference of the reinforcement pile 1, thereby facilitating the insertion of the reinforcement pile 1 into the soft soil foundation. After insertion, the screw 34 is rotated, the limiting cylinder 35 moves down, and the outer wall of the truncated cone of the extrusion block 36 gradually squeezes the plug plate 33, so that the plug plate 33 is rotated out of the through groove 31 and inserted Into the soft soil layer, thereby increasing the vertical connection area between the reinforcement pile 1 and the soil layer, increasing the anti-settling ability of the reinforcement pile 1, thereby improving the bearing capacity reinforcement effect of the foundation. After the reinforcement pile 1 is inserted into the soft soil foundation, the plug 43 is inserted into the connecting ear 41 and locked by the connecting bolt 44, so as to quickly connect the reinforcement piles 1 between the rows. The operation is fast, and all the reinforcement piles 1 are connected to each other to improve the reinforcement effect. Finally, concrete is poured into the connecting cavity 2 through the pouring hole 5. After the concrete is cured, the strength of the reinforcement pile 1 is increased, thereby improving the reinforcement effect.
