If the pile body is completely buried in the soil and the bottom of the cap is in contact with the soil, it is called a low cap pile foundation. If the upper part of the pile body is exposed to the ground and the bottom of the cap is above the ground, it is called a high cap pile foundation.

[0003] The pile foundation embedded structure is a structure for embedding and fixing the pile foundation. The existing embedded structure uses too many support rods and limit frames when in use, and the fixing structure is too complicated. The installation is very inconvenient, which affects the work progress. The embedded structure is easily affected by external factors and the deadweight of the pile foundation itself, resulting in uneven settlement. Based on this, the utility model designs a pile foundation embedded structure to solve the above problems. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-4 The utility model provides a technical solution: a pile foundation embedded structure, including a pile foundation body 1 and a base 2, the base 2 has an installation cavity 3, the pile foundation body 1 is connected to the base 2 through the installation cavity 3, the bottom end of the base 2 is fixedly connected to the box-type base 12, and any two opposite sides of the base 2 are provided with a plurality of grooves 4. It is worth noting that any two opposite sides of the base 2 can be the left side and the right side, or the front side and the rear side. The pile foundation body 1 has a groove 25 corresponding to the grooves 4. A reset structure is provided inside the groove 2 5, and the reset structure includes a sleeve 6, a reset spring 7, a push rod 8 and a fixed block 9. The sleeve 6 is fixed inside the groove 2 5, one end of the reset spring 7 is fixed inside the sleeve 6, and the other end of the reset spring 7 is fixedly connected to the push rod 8. The end of the push rod 8 away from the reset spring 7 is fixedly connected to the fixed block 9. The pile foundation body 1 is inserted into the installation cavity 3, so that the fixed block 9 located inside the sleeve 6 is engaged with the groove 1 4 under the action of the reset spring 7 to form an engaging structure, so that the pile foundation body 1 is embedded in the base 2.

[0027] Among them, the inner diameter of the installation cavity 3 is equal to the outer diameter of the pile foundation body 1, so that the pile foundation body 1 and the base 2 are connected more tightly, the groove 1 4 and the groove 2 5 are set as rectangular grooves that cooperate with the fixing block 9, which is convenient for the fixing block 9 to move inside the groove 1 4 and the groove 2 5, and the end of the fixing block 9 away from the push rod 8 is arc-shaped. The arc-shaped design converts the vertical pressure into the lateral pressure. The sleeve 6 is provided with a sliding groove that cooperates with the reset spring 7 and the push rod 8, which is convenient for the reset spring 7 and the push rod 8 to slide inside the sleeve 6. The length of the fixing block 9 is greater than the length of the groove 1 4, ensuring that the fixing block 9 can be engaged in the groove On groove one 4, the sum of the lengths of the sleeve 6, the push rod 8 and the fixed block 9 is greater than the sum of the lengths of groove one 4 and groove two 5, so that the end of the push rod 8 connected to the return spring 7 is always located inside the sleeve 6, and the sum of the lengths of the fixed block 9 and the sleeve 6 is less than the length of the groove two 5, ensuring that the fixed block 9 can be completely retracted in the groove two 5. The fixed block 9 is fixedly connected to the base 2 by bolts 11 to improve the stability of the embedded structure. The base 2 and the fixed block 9 are both provided with screw holes 10 that cooperate with the bolts 11, and the fixed block 9 and the base 2 are connected as a whole through the connection of the bolts 11.

[0028] See also Figure 1 and Figure 2 The base 2 is fixed on the box-type base 12, and the box-type base 12 can better bear the vertical pressure brought by the pile foundation body 1. Two cavities 13 are symmetrically opened at the four ports of the box-type base 12. The cavity 13 enhances the compressive strength of the box-type base 12 and improves the compensation capacity of the box-type base 12. Among them, the box-type base 12 is in a "cross" shape. The "cross" shape design increases the contact area between the embedded structure and the foundation, and the connection is tighter. There is an inner partition wall between the two cavities 13 to ensure the integrity and rigidity of the box-type base 12.

[0029] The overall working principle is that the pile foundation body 1 is slowly placed in the installation cavity 3 by hoisting. During this process, the lowest fixed block 9 slowly touches the base 2. At the moment of contact, the fixed block 9 is squeezed by the base 2. Under the action of pressure, the fixed block 9 begins to move toward the sleeve 6, so that the push rod 8 squeezes the reset spring 7 in the slide groove inside the sleeve 6 until the end of the fixed block 9 away from the push rod 8 is completely retracted into the groove 2 5. As the pile foundation body 1 descends, when the lowest groove 2 5 and the uppermost groove 1 4 are at the same horizontal plane, under the action of the reset spring 7 , the push rod 8 pushes the fixing block 9 into the groove 4, and the above working process is repeated during the continued descent of the pile foundation body 1 until the bottom surface of the pile foundation body 1 contacts the top surface of the box-type base 12. At this time, all the fixing blocks 9 are pushed into the groove 4 under the action of the reset spring 7, and the base 2 and the fixing block 9 are both provided with screw holes 10 that cooperate with the bolts 11. The bolts 11 are fixed to the base 2 through the screw holes 10, and then the bolts 11 are tightened. At this time, the box-type base 12 and the cavity 13 jointly bear the vertical gravity of the pile foundation body 1, and the entire pile foundation is embedded in the structure to complete the pile foundation embedding work.

[0030] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable ordinary technicians in the field to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the essence of the content of the utility model should be included in the protection scope of the utility model.
