Description

Technical Field

[0001] The utility model relates to the technical field of pile driving, in particular to a high-frequency vibration prevention pile driving structure for complex strata. Background Technique

[0002] In modern construction, pile driving operation is an important part of infrastructure construction. Especially when driving piles in complex strata, due to the non-uniformity of the strata and the influence of high-frequency vibration, the pile driving process is often accompanied by problems such as excessive vibration and uneven settlement. These problems not only affect the construction efficiency but also may cause damage to the surrounding environment. Therefore, it is particularly important to develop a structure that can effectively reduce high-frequency vibration and improve the stability of pile driving.

[0003] There are various types of pile driving structures in the prior art.

The main reason is that these structures do not fully consider the stratum characteristics in design, resulting in limited vibration damping effect, complex structure and high cost.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figure 1-2 , a high-frequency vibration prevention pile sinking structure for complex strata, including a pile sinking body 1, and a vibration guide assembly is arranged outside the pile sinking body 1.

[0023] Among them, the vibration guiding assembly includes a plurality of first steel rods 2. The number of the first steel rods 2 is two. The two first steel rods 2 are evenly distributed around the midpoint axis of the pile sinking body 1. An outer steel ring 3 is provided at one end of the first steel rod 2 away from the pile sinking body 1. A plurality of vibration guiding frames 4 are provided at the top of the outer steel ring 3. The vibration guiding frame 4 and the vibration guiding plate 7 are respectively a rigid vibration guiding frame and a steel vibration guiding plate. A second steel rod 5 is provided at the bottom of the vibration guiding frame 4. A vibration guiding spring 6 is provided at the bottom of the second steel rod 5. A vibration guiding plate 7 is provided at the bottom of the vibration guiding spring 6. A plurality of steel balls 8 are provided at the bottom of the vibration guiding plate 7. A steel plate 9 is provided at the bottom of the steel balls 8. A plurality of damping shock absorbers 10 are provided at the bottom of the steel plate 9. The number of the damping shock absorbers 10 is eight. The eight damping shock absorbers 10 are evenly distributed around the midpoint axis of the top of the soil inserting member 11. An inserting member 11 is provided at the bottom of the damping shock absorber 10. The bottom end of the inserting member 11 is tapered.

[0024] In this embodiment, the soil inserting member 11 can be inserted into the ground to provide a more stable installation for the pile sinking and can further reduce the vibration of the pile sinking.

[0025] In addition, the number of the steel balls 8 is eight. The eight steel balls 8 are evenly distributed around the midpoint axis of the bottom of the vibration guiding plate 7. Since the number of the steel balls 8 is eight and they are evenly distributed around, they can well absorb the vibration force and transmit it evenly downward.

[0026] The working principle of this embodiment is as follows:

[0027] During the pile sinking operation, the pile sinking body 1 is first placed at a predetermined position. Subsequently, the high-frequency vibration energy is transmitted to the vibration guiding frame 4 through the vibration guiding assembly. The vibration guiding frame 4 and the vibration guiding plate 7 work together to disperse and guide the vibration energy to the steel balls 8. The steel balls 8 are evenly distributed around the bottom of the vibration guiding plate 7 and can effectively absorb and disperse the vibration energy, reducing the direct impact on the pile sinking body 1. The steel plate 9 below the steel balls 8 further stabilizes the transmission path of the vibration energy, ensuring uniform energy distribution. The damping shock absorbers 10 below the steel plate 9 play a key shock absorption role. They are evenly distributed around the midpoint axis of the top of the soil inserting member 11 and can absorb the remaining vibration energy, preventing the vibration from being transmitted to the ground, thereby protecting the surrounding environment from damage. The tapered bottom end of the soil inserting member 11 helps the pile sinking structure to penetrate deeper into the formation, improving the stability and bearing capacity of the pile sinking.
