[0002] In the process of highway construction and maintenance, the treatment of soft soil foundation has always been an important challenge faced by engineers. Soft soil poses a serious threat to the stability and durability of roads due to its high water content, low bearing capacity and easy deformation. In order to ensure the long-term stability of the road structure, it is usually necessary to drive pipe piles into the soft soil foundation to provide sufficient bearing capacity and anti-deformation ability.

[0003] After searching, the patent document with application number 202310505117.4 discloses a bridge construction vibration pile driver, including a vibrator housing, the interior of the vibrator housing is movably connected with a support rod running through the upper and lower ends thereof, a fixed block is fixedly installed on the top of the outer surface of the support rod, and a pile clamp is fixedly installed on the bottom end of the support rod, a group of exciting springs are movably sleeved at the top of the outer surface of the support rod and located between the fixed block and the top of the vibrator housing, and another group of exciting springs are movably sleeved at the bottom of the outer surface of the support rod and located between the pile clamp and the bottom end of the vibrator housing. The bridge construction vibration pile driver provided in the present application can generate vibration along the central axis direction of the support rod when the eccentric block is triggered, thereby effectively reducing the vibration energy loss of the high vibration pile driver during operation.

[0004] However, traditional pile driving methods often have problems such as low efficiency, insufficient precision and great construction difficulty, especially in complex geological conditions, where these problems are more prominent.

[0005] With the continuous progress and innovation of engineering technology, the research and development of new pile driving equipment has become the key to solving the above problems. In this context, this patented technology came into being, aiming to provide a high-efficiency, accurate and easy-to-operate vibrating pile driver for soft soil foundation of highways. The pile driver adopts a number of innovative technologies, including a composite shock absorption system, an eccentric shaft and gear transmission mechanism, synchronous control of the clamping mechanism, hydraulic telescopic control of the positioning clamping rod, staggered setting and limit design of the positioning clamping rod, double clamping mechanism inside and outside the pile, and ball bearings to reduce sliding resistance.

[0006] The comprehensive application of these technologies enables the pile driver to efficiently and stably carry out pile driving operations in soft soil foundations, while ensuring the precise positioning and stable support of the piles. In addition, the introduction of the shock absorption system and ball design also effectively reduces the vibration and resistance during the construction process, improving the safety and comfort of operation. In short, this patented technology provides a new solution for the treatment of soft soil foundations of highways through a series of technological innovations, and is expected to play an important role in future road construction.

DETAILED DESCRIPTION

[0024] 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 in 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.

[0025] The utility model provides Figure 1 and Figure 2 A highway soft soil foundation vibrating pile driver shown in the figure comprises a vibrator 1, the upper end of the vibrator 1 is elastically connected to a lifting head 4 through a plurality of shock-absorbing slide bars 2 and a plurality of shock-absorbing springs 3, the vibrator 1 generates vibrations through the rotation of two eccentric shafts 7 inside, and the two eccentric shafts 7 are connected by gears, the eccentric shaft 7 on the left is connected to a vibration motor 6 through a connecting mechanism 8, and is driven by the vibration motor 6, the vibrator 1 reduces the influence of vibration on the lifting head 4 through a plurality of shock-absorbing slide bars 2 and a plurality of shock-absorbing springs 3, since the lifting head 4 is connected to the lifting rope through the lifting rope connecting head 5 at the center of the upper end, and is connected to the crane through the lifting rope, the vibrator 1 can reduce the influence of vibration on the lifting rope and the crane through the plurality of shock-absorbing slide bars 2 and a plurality of shock-absorbing springs 3, and the two clamping A rotating tooth connected to the lower end of the clamping motor 9 is provided between the racks of the mechanism 11, and the synchronous movement away and approaching is performed by the rotation of the rotating tooth. The rotating tooth is connected to the inside of the lower end of the clamping motor 9 through the rotation of the rotating shaft, and is located inside the center of the upper end of the limiting cross bar 10. The pile driver is clamped on the outside of the pipe pile by the claws of the two clamping mechanisms 11, and the two positioning clamping rods 12 are opened to both sides and rest on the inner wall of the pipe pile, so that the positioning clamping rods 12 can cooperate with the clamping mechanism 11 to clamp the pipe wall of the pipe pile, so that the pipe pile can be clamped on the whole and the pipe wall of the pipe pile at the same time by the two clamping mechanisms 11 and the two positioning clamping rods 12, so that the pile driver can clamp the pipe pile more firmly and stably, and at the same time, the pile driver can limit the upper end face of the pipe pile by the outer wall of the lower end of the limiting cross bar 10.

[0026] like Figure 3 and Figure 4As shown, the two positioning clamping rods 12 are connected to the left and right ends of the positioning oil box 13 through the outer hydraulic rod 15, the inner hydraulic rod 17 and the connecting slide block 19. Since the positioning oil box 13 is provided with hydraulic oil inside and is connected with the hydraulic control mechanism through the hydraulic pipe at the center of the front end, the two positioning clamping rods 12 can be telescopically controlled by the hydraulic control mechanism connected to the front end of the positioning oil box 13. The two outer hydraulic rods 15 are slidably connected to the inside of the positioning oil box 13 through the telescopic holes 14 on both sides, and the two outer hydraulic rods 15 are staggered front and back, so the telescopic movement of the two outer hydraulic rods 15 inside the positioning oil box 13 does not affect each other, and can be effective. The telescopic length of the positioning clamp rod 12 is effectively increased, and the two outer hydraulic rods 15 can be limited in position by two limiting rings 16 arranged on the outside, which can prevent the inner hydraulic rod 17 from slipping out from the inside of the adjusting oil box 13 and prevent the end of the outer hydraulic rod 15 located inside the adjusting oil box 13 from contacting the inner wall of the adjusting oil box 13, resulting in the hydraulic oil being unable to enter the inside.

Since the two positioning clamping rods 12 are arranged in an arc surface at one end close to the clamping mechanism 11, the two positioning clamping rods 12 can slide on the inner wall of the pipe pile to the left and right sides of the center of the pipe pile, so that the two positioning clamping rods 12 can be moved from the inner wall of the pipe pile. The part can limit the pipe pile, and at the same time, the adjusting oil box 13 can be positioned to the upper side of the center of the upper end of the pipe pile, so that the limiting cross bar 10 is positioned to the upper side of the center of the upper end of the pipe pile. At this time, the two clamping mechanisms 11 are controlled by the clamping motor 9 to slide toward the middle to clamp the pipe pile externally, so that the two clamping mechanisms 11 can not only clamp the pipe pile as a whole, but also cooperate with the two positioning clamping rods 12 to clamp the pipe wall of the pipe pile, and can position the pipe pile to the center of the lower end of the pile driver, so that the pile driver can stably sink the pipe pile and make the pipe pile more accurately driven into the predetermined position.

[0028] Preferably, a plurality of balls 20 are rollingly connected inside the arc surface of the positioning clamp rod 12 near one end of the clamping mechanism 11 , so that the positioning clamp rod 12 can convert sliding on the inner wall of the pile into rolling through the plurality of balls 20 , thereby reducing the opening resistance of the positioning clamp rod 12 .
