Description

Technical Field

[0001] This invention belongs to the field of pile foundation construction technology, specifically relating to an adjustable pile foundation construction device and its usage method. Background Technology

[0002] In the construction process, the construction of pile foundations is particularly important, as it relates to the overall quality of the railway. During the pile foundation construction process, in order to prevent the inner wall of the pile hole from collapsing, it is necessary to install a protective casing inside the pile hole for support, so as to facilitate the normal progress of subsequent pile foundation construction. For example, the existing patent with publication number CN214423376U discloses "a pile foundation engineering construction device, belonging to the field of pile foundation construction, the key technical point of which is to include a steel protective casing" and the existing patent with publication number CN209741833U discloses "a pile foundation engineering construction device, including several protective casing units". It can be seen that the use of protective casings is a common construction scheme in the pile foundation construction process, and such protective casings as pile foundation construction devices have been widely used in the pile foundation construction process.

[0003] Existing casings, as a common pile foundation construction device, have limited length and cannot be adjusted to lengthen or shorten according to different pile hole depths, resulting in low overall flexibility. Although existing technologies can use multiple casings stacked on top of each other to change the overall length, this method has poor overall stability and is cumbersome in practical application. Therefore, this invention proposes an adjustable pile foundation construction device and its usage method. Summary of the Invention

[0004] The purpose of this invention is to provide an adjustable pile foundation construction device and its usage method to solve the problem mentioned in the background art that the length of the casing cannot be adjusted to lengthen or shorten according to different pile hole depths in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an adjustable pile foundation construction device, comprising a central cylinder and two end cylinders movably sleeved at both ends of the central cylinder, allowing adjustment of the overall length of the device through sliding of the end cylinders. Each of the two end cylinders has an inner cylinder groove for insertion into the central cylinder. The end of the central cylinder is inserted into the inner side of the inner cylinder groove. An adjustment mechanism is provided between the central cylinder and the end cylinders. The adjustment mechanism includes a rectangular insert, a rectangular slot, a rod, and a circular slot. Rectangular slots are provided on the front and rear surfaces of the end cylinders for insertion of the rectangular insert. The rod is fixed to... The inner surface of the rectangular insert block can move along with the rectangular insert block. Multiple circular slots are provided on both the front and rear surfaces of the central cylinder for the insertion of the end of the insert rod. The rectangular insert block is installed in the rectangular slot, and the end of the insert rod passes through and is inserted into one of the circular slots, providing a stable limiting function between the central cylinder and the end cylinder. Side sliders are movably provided on the inner surface of the rectangular insert block relative to the top and bottom of the insert rod. Two rectangular notches are symmetrically provided on one side of the inner wall of the rectangular slot for the side sliders to enter. A limit rod is fixed to one side of the inner wall of the rectangular notch. One end of the slider is embedded in a rectangular notch and fitted onto a limiting rod for stable positioning of the rectangular insert. The outer surface of the rectangular insert has a corresponding actuating structure for the side slider. This actuating structure includes an inner groove, a spring, an inner slider, a connecting block, and a lever. Both ends of the rectangular insert have inner grooves, and the inner slider is movably mounted within each groove via a spring. The inner slider can be reset by the spring after being pushed. The other end of the side slider passes through the inner groove and is fixed to the inner slider, allowing it to slide together with the inner slider. The outer surface of the rectangular insert has a connecting rod... The rectangular insert has a connecting groove. The toggle block is located on the outer surface of the rectangular insert. A connecting block is fixed to one side of the inner slider. The connecting block passes through the connecting groove to the outer surface of the rectangular insert and is fixed to the toggle block. The side slider can be moved by the toggle block to release the restriction on the rectangular insert, thereby realizing the disassembly and assembly of the rectangular insert and facilitating subsequent sliding adjustment of the end tube. The inner slider has a cylindrical groove, and one end of the spring is embedded in the cylindrical groove to ensure the stable installation of the spring. The inner surface of the rectangular insert also has an inner slide rail, which corresponds to the side slider, allowing the side slider to slide smoothly.

[0006] Preferably, a rotating block is rotatably mounted on the outer surface of the rectangular insert, and the rotating block is located between the two levers. The rotating block can be rotated 90 degrees to a vertical position to block and limit the two levers, preventing them from being accidentally pushed during daily use and ensuring the installation stability of the rectangular insert. A central rod is fixed to the outer surface of the rectangular insert relative to the two levers, and the rotating block is rotatably sleeved on the central rod. The rotating block can be rotated to a horizontal position to allow normal lever manipulation. Rubber pads are embedded and fixed to the top and bottom of the outer surface of the rectangular insert relative to the central rod, and the surface of the rubber pads has an integral circular rubber protrusion. Rectangular locking holes are opened on both ends of the rotating block for auxiliary limiting when the rotating block is rotated to a vertical position.

[0007] A method for using an adjustable pile foundation construction device includes the following steps:

[0008] Step 1: First, simultaneously move the two levers on the outer surface of the rectangular insert towards the center of the rectangular insert, causing the side slider to also move towards the center of the rectangular insert, ultimately separating the side slider from the limiting rod and releasing the limiting effect on the rectangular insert.

[0009] Step 2: At this point, pull the rectangular insert out from the inside of the rectangular slot, and move the end of the insert rod out of the circular slot to release the connection limit between the end tube and the center tube.

[0010] Step 3: Adjust the distance between the two end tubes according to the depth of the pile hole to be inserted. When adjusting, slide the end tube on the surface of the center tube to adjust the length of the entire device. After adjusting to the appropriate length, move the two levers and push the rectangular insert into the inside of the rectangular slot, so that the end of the insert rod is inserted into the circular slot in another position. This will limit the distance between the end tube and the center tube again. Then release the levers, so that the spring pushes the inner slider back and the side slider can be fitted on the limiting rod, thus achieving stable limiting of the rectangular insert and completing the stable installation of the rectangular insert.

[0011] Step 4: After adjusting the length of the device, it can be lowered directly into the pile hole to be constructed using external hoisting equipment. The end tube and center tube will then provide stable support to the inner wall of the pile hole.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: by setting an adjustable cylindrical support consisting of two end tubes and a central tube, the length of the device can be adjusted to be stretched or shortened according to different pile hole depths, which greatly improves the overall flexibility of the device. At the same time, the overall length adjustment method is very simple and stable, and easy for operators to adjust on site, thereby providing support for the inner wall of pile holes at different depths and ensuring the smooth progress of subsequent pile foundation engineering in the pile hole.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example

[0023] Please see Figures 1 to 7 The present invention provides a technical solution: an adjustable pile foundation construction device, including a central cylinder 2 and two end cylinders 1 movably sleeved at both ends of the central cylinder 2. The end cylinders 1 can slide at the ends of the central cylinder 2 to realize the adjustment of the overall length of the device. The inner sides of the two end cylinders 1 are provided with inner cylinder grooves 5 corresponding to the central cylinder 2 for the smooth insertion and sliding of the central cylinder 2. The end of the central cylinder 2 is inserted into the inner side of the inner cylinder groove 5. An adjustment mechanism is provided between the central cylinder 2 and the end cylinders 1.

[0024] The adjustment mechanism includes a rectangular insert 3, a rectangular slot 6, a rod 11, and a circular slot 4. The front and rear surfaces of the end cylinder 1 are provided with rectangular slots 6 corresponding to the rectangular insert 3 for installation. The rod 11 is welded to the inner surface of the rectangular insert 3. The front and rear surfaces of the center cylinder 2 are provided with multiple circular slots 4 corresponding to the rod 11 for insertion. The rectangular insert 3 is installed in the rectangular slot 6, and the end of the rod 11 passes through and is inserted into one of the circular slots 4, thus achieving connection and limiting between the center cylinder 2 and the end cylinder 1. Side sliders 15 are movably provided on the inner surface of the rectangular insert 3 relative to the top and bottom of the rod 11. Two rectangular notches 16 corresponding to the side sliders 15 are symmetrically provided on one side of the inner wall of the rectangular slot 6 for the side sliders 15 to enter. A limiting rod 17 is welded to one side of the inner wall of the rectangular notch 16. One end of the side slider 15 is embedded in the rectangular notch 16 and fitted onto the limiting rod 17, thus achieving installation of the rectangular insert 3. To ensure the installation stability of the rectangular insert 3, the outer surface of the rectangular insert 3 is provided with a toggle structure corresponding to the side slider 15. The toggle structure includes an inner groove 12, a spring 13, an inner slider 14, a connecting block 18, and a toggle block 7. Both ends of the rectangular insert 3 are provided with inner grooves 12, and the inner slider 14 is movably installed in the inner groove 12 through the spring 13. The other end of the side slider 15 passes through the inner side of the inner groove 12 and is fixed to the inner slider 14. The inner slider 14 can slide together with the side slider 15. The outer surface of the rectangular insert 3 is provided with a connecting groove 19 corresponding to the connecting block 18. The toggle block 7 is provided on the outer surface of the rectangular insert 3. The connecting block 18 is welded to one side of the inner slider 14, and the connecting block 18 passes through the connecting groove 19 to the outer surface of the rectangular insert 3 and is fixed to the toggle block 7. The inner slider 14 and the side slider 15 can slide together by toggle the toggle block 7, thereby realizing the disassembly and assembly of the rectangular insert 3, so as to facilitate the subsequent sliding adjustment of the end cylinder 1.

[0025] In this embodiment, preferably, the inner slider 14 has a cylindrical groove inside, and one end of the spring 13 is embedded in the cylindrical groove to improve the installation stability of the spring 13. The inner surface of the rectangular insert 3 also has an inner slide corresponding to the inner slide groove 12. The inner slide corresponds to the side slider 15 and allows the side slider 15 to pass through and slide.

[0026] In this embodiment, preferably, a rotating block 8 is rotatably mounted on the outer surface of the rectangular insert 3, and the rotating block 8 is located between the two levers 7. During daily use, the rotating block 8 can be rotated to a vertical position, thereby providing support between the two levers 7 and preventing the levers 7 from being accidentally pushed. When the levers 7 need to be moved later, the rotating block 8 can simply be rotated back to a horizontal position. A central rod is fixed between the two levers 7 on the outer surface of the rectangular insert 3, and the rotating block 8 is rotatably sleeved on the central rod, allowing the rotating block 8 to rotate smoothly. Rubber pads are embedded and fixed on the outer surface of the rectangular insert 3 at the top and bottom of the central rod, and the surface of the rubber pads is provided with an integral circular rubber protrusion 9. Rectangular locking holes 10 corresponding to the circular rubber protrusions 9 are opened on both ends of the rotating block 8. When the rotating block 8 is rotated to a vertical position, the circular rubber protrusions 9 will lock into the rectangular locking holes 10 to limit the rotating block 8.

[0027] A method for using an adjustable pile foundation construction device includes the following steps:

[0028] Step 1: First, move the two pry bars 7 on the outer surface of the rectangular insert 3 towards the center of the rectangular insert 3 at the same time, causing the connecting block 18 to slide with the inner slider 14 and compress the spring 13, causing the side slider 15 to move with the inner slider 14 and separate the side slider 15 from the limiting rod 17, thereby releasing the limitation on the rectangular insert 3 and the insert rod 11.

[0029] Step 2: At this time, pull the rectangular insert 3 out from the inside of the rectangular slot 6, so that the end of the insert rod 11 moves out of the circular slot 4, thereby releasing the connection limit between the end tube 1 and the center tube 2.

[0030] Step 3: Adjust the distance between the two end cylinders 1 according to the depth of the pile hole to be inserted. When adjusting, slide the end cylinder 1 on the surface of the center cylinder 2 to change the distance between the two end cylinders 1, thereby adjusting the length of the entire device. After adjusting to the appropriate length, move the two levers 7 to make the side slider 15 slide with the inner slider 14. Then push the rectangular insert 3 into the inside of the rectangular slot 6 and make the end of the insert rod 11 insert into the circular slot 4 in other positions. This will limit the distance between the end cylinder 1 and the center cylinder 2 again. At this time, the side slider 15 will also be inserted into the rectangular notch 16. Release the levers 7 to make the spring 13 push the inner slider 14 back and make the side slider 15 spring back. Finally, the side slider 15 can be put on the limiting rod 17 to achieve stable limiting of the rectangular insert 3 and complete the installation of the rectangular insert 3.

[0031] Step 4: After adjusting the length of the device, it can be lowered directly into the pile hole to be constructed using external hoisting equipment. The end tube 1 and the center tube 2 will provide stable support for the inner wall of the pile hole.

[0032] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
