Description

Technical Field

[0001] The invention relates to the field of highway bridge construction, and in particular to a pile foundation construction device based on bridge engineering. Background Art

[0002] A pile foundation is a deep foundation that connects the tops of several piles into a whole through a cap to jointly bear dynamic and static loads. A pile is a vertical or inclined foundation component set in the soil. Its function is to penetrate soft, highly compressible soil layers or water and transfer the load borne by the pile to a harder, denser or less compressible bearing layer of the foundation. We usually call the piles in the pile foundation foundation piles.

[0003] The pile foundation of a bridge is the load-bearing component of the bridge during the overall construction process. Structurally, it directly connects the foundation and the bridge deck. Since the pile foundation plays a very important role in the overall bridge, how to ensure that the pile foundation is firmly coordinated with the foundation has become a research topic in the field of construction.

[0004] The invention patent with Chinese patent application number 202410814555.3 discloses a pile foundation construction fixing device, which relates to the field of foundation pit construction, including a pile foundation construction base, the pile foundation construction base is used for anchoring with the ground, the pile foundation construction base is provided with a drill rod guide channel for locating the pile foundation hole, and both sides of the drill rod guide channel provided by the pile foundation construction base are provided with movable mechanisms for positioning and guiding the drill rod and can be movably arranged; the movable mechanisms all include a fixed base, the bottom end of the fixed base is connected and fixed to the pile foundation construction base on one side of the drill rod guide channel, and one end of the two fixed bases arranged oppositely is respectively provided with a guide hoop for positioning and guiding the drill rod, and the guide hoop and the fixed base are movably arranged. Through this fixing device, the "verticality" of the drill rod drilling can be observed and judged at any time, so that during the drilling of the foundation pit pile foundation, correction and adjustment can be made at any time, so as to ensure the "verticality" and quality requirements of the foundation pit pile foundation drilling. The technical solution proposed in the above invention improves the verticality of the pile foundation during the subsequent placement by ensuring the verticality of the pile foundation drilling. However, during the pile foundation placement process, there will still be external environmental factors such as crosswinds that may cause the verticality of the device to be unbalanced, thereby affecting the load-bearing performance and service life of the overall bridge in the later stage. Summary of the invention

[0005] Therefore, in order to solve the above technical problems, the present invention proposes a pile foundation construction device based on bridge engineering, which solves the technical problem that the pile foundation tilts during the process of sinking to the foundation due to external factors during bridge construction.

[0006] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a pile foundation construction device based on bridge engineering, comprising a support base for cooperating with a foundation, an auxiliary positioning device arranged on the support base, the support base is fixedly arranged on the foundation, the support base comprises an integrally formed support horizontal plate and a support vertical frame, the support vertical frame is arranged at the center position of the support horizontal plate, the support vertical frame and the support horizontal plate are perpendicular to each other, a first connecting through hole is arranged on the support vertical frame, the first connecting through hole penetrates the support vertical frame and continues to penetrate the support horizontal plate downward; The auxiliary positioning device is disposed in the first connecting through hole, and the auxiliary positioning device can be raised and lowered along the central axis direction of the first connecting through hole to receive the pile foundation.

[0007] Furthermore, the supporting transverse plate is provided with threaded holes on its four edges, and the supporting transverse plate is fixedly matched with the foundation by screws.

[0008] Furthermore, the auxiliary positioning device includes a connecting main pipe and a folding plate arranged at the end of the connecting main pipe. The folding plate is arranged on the connecting main pipe in a surrounding state. In an initial state, the angle between the folding plate and the central axis of the connecting main pipe is 45°-60°. When subjected to external force, the folding plate will shrink toward the central axis of the connecting main pipe until it is parallel to the central axis of the connecting main pipe.

[0009] Furthermore, a first guide groove is provided in the first connecting through hole, a first convex strip is provided on the outer circumferential side surface of the connecting main pipe, the first convex strip and the first guide groove are engaged with each other, a positioning hole is provided on the outer circumferential side surface of the supporting stand, the positioning hole is perpendicular to the first connecting through hole and passes through the first connecting through hole.

[0010] Furthermore, a second guide groove is provided on the inner circumferential side surface of the connecting main pipe, and projections of the second guide groove and the first guide groove on the vertical plane do not overlap each other.

[0011] Furthermore, a second convex strip is provided in the second guide groove, and the second guide groove vertically penetrates upward to the upper end of the connecting main pipe.

[0012] Furthermore, a driven gear is provided on the connecting main pipe in the second guide groove, the driven gear is provided at the top position of the second guide groove, the driven gear is provided with a first transmission tooth, the second convex strip is provided with a second transmission tooth, and the gathering plate is provided with a third transmission tooth. The first transmission tooth and the second transmission tooth are both meshed with the third transmission tooth, and the second convex strip and the gathering plate are provided at the left and right ends of the driven gear.

[0013] Furthermore, an elastic ball is provided on the second convex strip, and the elastic ball is arranged on one side of the second convex strip close to the inner side surface of the connecting main pipe. When the elastic ball is not subjected to force, it protrudes outward to a height higher than the surface of the second convex strip, and when subjected to force, it shrinks inward to a height flush with the surface of the second convex strip.

[0014] Furthermore, a buffer layer is provided on one side surface of the gathering plate close to the central axis of the connecting main pipe.

[0015] Furthermore, a vibration motor is integrated in the buffer layer, and the vibration motor automatically starts to perform vibration operation after the pile foundation enters the connection main pipe and releases the elastic ball.

[0016] By adopting the above technical solution, the beneficial effects of the present invention are: 1. Compared with the existing pile foundation construction devices for bridge projects, the advantage of the present invention is that it can ensure that the bridge pile foundation, especially the prefabricated beam bridge pile foundation, can be accurately positioned and kept in a vertical state during the installation process and firmly cooperate with the foundation. Specifically, during the installation process of the present invention, a support base is pre-arranged for stable cooperation with the foundation, and then the pile foundation below is hoisted from top to bottom to cooperate with the foundation, wherein the support base includes a support cross plate for improving the support performance and a support frame for receiving the pile foundation, wherein the support cross plate increases its stability by increasing the contact area with the foundation.

[0017] 2. The supporting horizontal plate in the present invention is stably matched with the foundation by fixing with screws on all sides, wherein the screw fixing method is a relatively stable and stable method in the field of building construction.

[0018] 3. The present invention further provides an auxiliary positioning device, which serves as a main function device and is connected to the support base in a movable connection manner, which is convenient for disassembly and assembly and on-site construction.

[0019] 4. The auxiliary positioning device in the present invention includes a connecting main pipe and a retracting plate, wherein the connecting main pipe is used to stably cooperate with the supporting base, and the function of the retracting plate is to be in an open state in the initial state, and the open state can produce a larger accommodation area on the horizontal plane, that is, it can have better tolerance for pile foundations lowered from high altitudes. Although the lowered pile foundation is affected by environmental factors such as crosswinds during the lowering process, it can be guaranteed that as long as it falls into the retracting area of ​​the retracting plate, it can continue to be lowered in a perfect state to cooperate with the foundation, and as the pile foundation is continuously lowered, the retracting plate will have a process of retracting toward the central axis of the connecting main pipe, and this process can assist the pile foundation to adjust its state, so that it continues to fall in a state perpendicular to the foundation, and when it falls to enter the first connecting through hole through the connecting main pipe, the connecting main pipe and the first connecting through hole jointly provide radial auxiliary positioning for the pile foundation, so that the pile foundation can be installed in a state completely perpendicular to the supporting base.

[0020] 5. The pile foundation in the present invention will pass through the retracting plate and then contact the elastic ball on the second convex strip during the lowering process, and the elastic ball will begin to play a positioning role, that is, when the elastic ball is subjected to the gravity generated by the falling of the pile foundation, it will drive the second convex strip to move downward, and the downward movement of the second convex strip will drive the driven gear to rotate, and further drive the third transmission tooth on the retracting plate to rotate. At this time, the retracting plate will synchronously produce an inward retracting action, and when the retracting plate retracts inward to surround the pile foundation, it stops working. At this time, the pile foundation continues to move downward, and the elastic ball that continues to be stressed will shrink inward into the second convex strip, which will not affect the falling installation process of the pile foundation.

[0021] 6. In the present invention, a buffer layer is provided on one side of the gathering plate close to the central axis of the connecting main pipe. The purpose of the buffer layer is to protect the outer surface of the pile foundation from damage while also protecting the gathering plate from damage, thereby providing a flexible contact surface for buffering between the two.

[0022] 7. The present invention integrates a vibration motor in the buffer layer, and the vibration motor works in conjunction with an elastic ball bearing, which serves as a starting point for driving the second convex strip to work. That is, when the folding plate contracts inward, the vibration motor starts to work, driving the folding plate to vibrate. The purpose of the vibration of the folding plate is to assist the pile foundation to quickly move toward the center when it contacts the side wall of the folding plate. At the same time, when the vibration of the folding plate is transmitted to the pile foundation, it can also shake off impurities on the outer surface of the pile foundation, so that it can smoothly enter the first connecting through hole on the connecting main pipe and the support base for construction and installation.
