Description

Technical Field

[0001] This utility model belongs to the field of pile foundation extraction technology, specifically relating to a pile foundation extraction device for civil engineering. Background Technology

[0002] In civil engineering, the core function of pile foundations is to transfer the loads of gravity, wind, earthquakes and other factors from the superstructure to the soil or rock layers with high bearing capacity and low deformation deep underground, so as to ensure the safety and stability of the building and control settlement and displacement.

[0003] When it is necessary to pull out abandoned piles, the traditional extraction device usually adopts the method of lifting directly. However, the soil around the pile is relatively stable, and the power required for direct lifting is large and the time is long.

[0004] To address the problems raised in the background art, those skilled in the art have proposed a pile extraction device for civil engineering.

[0005] The information disclosed above in this background section is only intended to enhance the understanding of the background section of this utility model, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0006] The purpose of this utility model is to provide a pile foundation extraction device for civil engineering to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A pile extraction device for civil engineering includes:

[0009] The auxiliary mechanism includes a soil foundation and a pile foundation body inserted into the soil foundation. The pile foundation body has several base plates and insertion slots on its periphery. A column is fixedly installed on the upper surface of the base plate. A sliding groove is opened on the column. A built-in slider is slidably installed in the sliding groove. A crossbar is connected to the built-in slider. A downward hammering component is connected to the crossbar. A wedge-shaped auxiliary rod is inserted into the insertion slot. One end of the downward hammering component is in contact with the wedge-shaped auxiliary rod.

[0010] The extraction mechanism includes a collar installed on the periphery of the pile foundation body. The collar is an annular plate structure. Several compression components are fixedly installed on the periphery of the collar. One end of each compression component is provided with a compression plate. The compression plate is in compression fit with the periphery of the pile foundation body. Several hanging rings are provided on the collar, and lifting components are provided on the hanging rings.

[0011] Preferably, a lifting cylinder is fixedly installed on the lower surface inside the sliding groove. One end of the lifting cylinder includes a lifting rod, and one end of the lifting rod is connected to the built-in slider.

[0012] Preferably, the impact assembly includes a boom fixedly connected to the crossbar, and a vibratory hammer is connected to the end of the boom away from the crossbar.

[0013] Preferably, the extrusion assembly includes a jack fixedly mounted on a collar, one end of which includes a telescopic rod, and one end of the telescopic rod is fixedly connected to the extrusion plate.

[0014] Preferably, the lifting assembly includes a traction cable fixedly connected to the hanging ring, and a top plate is fixedly connected to the end of the traction cable away from the hanging ring.

[0015] Preferably, a hook is fixedly installed on the upper surface of the top plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] (1) This utility model sets up multiple hammering components and wedge-shaped auxiliary rods around the main body of the pile foundation. The wedge-shaped auxiliary rods can be inserted downward by the vertical excitation force generated by the high-speed rotation of the eccentric block generated by the vibratory hammer. This allows the wedge-shaped auxiliary rods to resonate with the surrounding soil, thereby creating gaps and reducing the side friction and end resistance between the main body of the pile foundation and the soil. This improves the effort required to pull the pile. When inserting the wedge-shaped auxiliary rods, high-pressure water can also be used to impact the insertion groove, which can further loosen the soil. The collar with the squeezing component can work with the lifting component to pull the main body of the pile foundation that has been loosened upward. The whole operation process is more labor-saving.

[0018] (2) By setting a top plate with hooks, the present invention can use a lifting device to hook it to the hooks. With the soil loosening measures of the auxiliary mechanism, the main body of the pile foundation can be continuously pulled upward. The jack with the compression plate installed horizontally on the collar can tightly fix the main body of the pile foundation and prevent it from falling off during the pulling process.

[0019] The above overview is for illustrative purposes only and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features of the present invention will become readily apparent from the accompanying drawings and the following detailed description.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1:

[0027] Please see Figures 1-4 As shown, a pile extraction device for civil engineering includes:

[0028] The auxiliary mechanism includes a soil foundation 1 and a pile foundation body 21 inserted into the soil foundation 1. The pile foundation body 21 has several base plates 2 and insertion slots 10 on its periphery. A column 3 is fixedly installed on the upper surface of the base plate 2. A sliding groove 4 is opened on the column 3. A built-in slider 5 is slidably installed in the sliding groove 4. A crossbar 6 is connected to the built-in slider 5. A downward hammering component is connected to the crossbar 6. A wedge-shaped auxiliary rod 9 is inserted into the insertion slot 10. One end of the downward hammering component is in contact with the wedge-shaped auxiliary rod 9.

[0029] The extraction mechanism includes a collar 13 installed on the side of the pile foundation body 21. The collar 13 is a ring plate structure. Several compression components are fixedly installed on the side of the collar 13. One end of the compression component is provided with a compression plate 16. The compression plate 16 is in compression fit with the side of the pile foundation body 21. Several hanging rings 17 are provided on the collar 13. Lifting components are provided on the hanging rings 17.

[0030] As can be seen from the above, this device, by setting up multiple downward hammering components around the pile foundation body 21 and wedge-shaped auxiliary rods 9, can insert the wedge-shaped auxiliary rods 9 downward through the vertical excitation force generated by the high-speed rotation of the eccentric block generated by the vibratory hammer 8. This allows the wedge-shaped auxiliary rods 9 to resonate with the surrounding soil, thereby creating gaps and reducing the lateral friction and end resistance between the pile foundation body 21 and the soil, thus improving the effort required to pull the pile. When inserting the wedge-shaped auxiliary rods 9, high-pressure water can also be used to impact the insertion groove 10, which can further loosen the soil. The collar 13 with the squeezing component can cooperate with the lifting component to pull the pile foundation body 21, which has already been loosened, upward. The entire operation process is more labor-saving.

[0031] Example 2:

[0032] Please see Figures 1-4 As shown, a lifting cylinder 11 is fixedly installed on the lower surface inside the sliding groove 4. One end of the lifting cylinder 11 includes a lifting rod 12, and one end of the lifting rod 12 is connected to the built-in slider 5.

[0035] Specifically, the lifting assembly includes a tension cable 18 fixedly connected to the hanging ring 17, with a top plate 19 fixedly connected to the end of the tension cable 18 away from the hanging ring 17.

[0036] Specifically, hooks 20 are fixedly installed on the upper surface of the top plate 19.

[0037] As can be seen from the above, by setting a top plate 19 with hooks 20, the present invention can use a lifting device to hook it to the hooks 20. With the soil loosening measures of the auxiliary mechanism, the pile foundation body 21 can be continuously pulled upward. The jack 14 with a compression plate 16 installed horizontally on the collar 13 can tightly fix the pile foundation body 21 and prevent it from falling off during the pulling process.
