Description

Technical Field

[0001] The invention relates to the technical field of pile foundation detection equipment, in particular to a self-balancing detection device for horizontal bearing capacity of a pile foundation. Background Art

[0002] Self-balancing detection of pile foundation horizontal bearing capacity usually refers to the use of self-balancing method to detect the horizontal bearing capacity of pile foundation in pile foundation engineering. This method is based on a static load test method that seeks loading reaction force inside the pile foundation. It is particularly suitable for scenarios where some traditional detection methods are difficult to achieve, such as water test piles, slope test piles, foundation pit bottom test piles, narrow site test piles, etc.

[0003] The principle of self-balancing pile foundation testing is that during the construction process, a special loading device, the load box, is finalized and manufactured according to the pile bearing capacity parameter requirements, and is placed at the bottom of the pile body or a specified position (usually the balance point of the pile body) to make the reaction forces of the upper and lower sections of the pile equal to maintain the loading. When the load box is in use, the opening in the middle of the load box needs to be sealed after the pouring is completed to ensure its performance during use. The size of the opening of the load box is related to the difficulty and effect of the sealing treatment. An opening that is too large may increase the difficulty of sealing and reduce the sealing effect, while an opening that is too small may cause inconvenience to the sealing operation, resulting in reduced engineering efficiency during use. Improvements need to be made to this problem. Summary of the invention

[0009] According to the above technical solution, the telescopic end of the bidirectional telescopic rod passes through the top of the fixed barrel and the bottom of the connecting tube and extends into the connecting tube to be fixedly connected to the bottom of the lifting plate, so that the bidirectional telescopic rod can drive the lifting plate when working.

[0010] According to the above technical solution, a sliding groove is opened in the lifting plate, and the lifting plate is slidably connected to the outer wall of the connecting tube through the sliding groove, so that the two-way telescopic rod can control the lifting plate to rise and fall on the outer wall of the connecting tube during operation.

A rotating frame 3 is fixedly connected to the side of the bottom of the deformable arc plate close to the connecting tube, and the side of the connecting push rod away from the connecting frame 3 is rotatably connected to the middle part of the rotating frame 3, so that the connecting push rod can be connected to the deformable arc plate through the rotating frame 3, and at the same time, the connecting frame 2 is connected to the deformable arc plate through the rotating frame 2.

At the same time, the size of the opening in the middle of the top sealing plate can be adjusted to avoid the opening being too large, which will cause the concrete to flow downward along the sealing top plate on the deformed arc plate during pouring, and avoid the opening being too large, which will cause uneven internal pressure distribution and affect the pouring effect. When the concrete pouring in the lower pile body is completed and needs to be sealed, the two-way telescopic rod is controlled to work, so that the two-way telescopic rod works to drive the lifting plate to move upward on the outer side of the connecting tube. When the lifting plate moves upward, the rotating frame 1 pushes the connecting frame 1, the connecting frame 2 and the connecting frame 3, so that the connecting frame 4 on the deformed arc plate rotates upward in the rotating block, so that the deformed arc plate and the rotating block are in the same horizontal plane. At this time, the sealing top plate and the circular plate are in the same plane, and multiple sealing top plates cooperate with the circular plate to seal the surface where they are located, so that the device can adjust the opening size as needed when in use, and has the function of adjusting the seal. Moreover, since the sealing top plate and the circular plate are provided on the upper and lower sides, when the sealing top plate on the lower side rotates, the top of the concrete in the lower pile body can be squeezed to make it compacted, and the sealing top plate and the circular plate on the top form a new bottom surface, so that the pouring will not be uneven due to depression during pouring, so that the work efficiency of the device is increased after it is put into construction; When performing the self-balancing test of the horizontal bearing capacity, the jack is controlled to work, and then the value fed back by the displacement meter is checked and recorded, so that the device can perform the self-balancing test of the horizontal bearing capacity of the pile foundation while working.

[0021] The sealing assembly 6 includes a connecting frame three 601, a connecting push rod 602, a deformable arc plate 603, a connecting frame four 604, a rotating block 605 and a sealing top plate 606. The connecting frame three 601 is hinged to the inner side of the connecting frame one 504, the connecting push rod 602 is fixedly connected to the top of the connecting frame three 601, the deformable arc plate 603 is rotatably connected to the side of the connecting push rod 602 away from the connecting frame three 601, the connecting frame four 604 is fixedly connected to the side of the deformable arc plate 603 close to the lifting plate 502, the rotating block 605 is fixedly connected to the outer side of the connecting push rod 602, and the sealing top plate 606 is fixedly connected to the top of the deformable arc plate 603.

[0022] The telescopic end of the bidirectional telescopic rod 501 passes through the top of the fixed barrel 405 and the bottom of the connecting tube 406 and extends into the connecting tube 406 to be fixedly connected to the bottom of the lifting plate 502, so that the bidirectional telescopic rod 501 can drive the lifting plate 502 when working.

[0023] A sliding groove is provided in the lifting plate 502, and the lifting plate 502 is slidably connected to the outer wall of the connecting tube 406 through the sliding groove, so that the two-way telescopic rod 501 can control the lifting plate 502 to rise and fall on the outer wall of the connecting tube 406 during operation.

[0024] The outer side of the bottom of the deformable arc plate 603 is fixedly connected to a rotating frame 2, and the connecting frame 2 505 is rotatably connected to the middle part of the rotating frame 2 on the side away from the connecting frame 1 504. The bottom of the deformable arc plate 603 is fixedly connected to a rotating frame 3 on the side close to the connecting tube 406. The connecting push rod 602 is rotatably connected to the middle part of the rotating frame 3 on the side away from the connecting frame 3 601, so that the connecting push rod 602 can be connected to the deformable arc plate 603 through the rotating frame 3, and at the same time, the connecting frame 2 505 is connected to the deformable arc plate 603 through the rotating frame 2.

[0026] When it is necessary to pour concrete, the two-way telescopic rod 501 is controlled to contract, so that the two-way telescopic rod 501 drives the lifting plate 502 to move downward on the outside of the connecting tube 406. At the same time, when the lifting plate 502 moves, the rotating frame 1 503 on the lifting plate 502 pulls the connecting frame 1 504. At this time, the connecting frame 1 504 pulls the connecting frame 2 505 and the connecting frame 3 601, so that the connecting push rod 602 on the connecting frame 3 601 drives the deformed arc plate 603 to rotate. Since the connecting frame 4 604 on the deformed arc plate 603 is rotatably connected to the middle part of the rotating block 605, the deformed arc plate 603 drives the sealing top plate 606 to approach the outer wall of the fixed barrel 405, and at the same time, the opening in the middle part of the load box 1 is enlarged, so that when pouring concrete, the pouring efficiency will not be reduced due to the opening being too small.

[0027] During pouring, the position of the lifting plate 502 is controlled by the two-way telescopic rod 501, so as to control the fitting angle between the deformable arc plate 603 and the outer side of the fixed barrel 405.

[0028] When the concrete in the lower pile body is poured and needs to be sealed, the two-way telescopic rod 501 is controlled to work, so that the two-way telescopic rod 501 works to drive the lifting plate 502 to move upward outside the connecting tube 406. When the lifting plate 502 moves upward, the rotating frame 1 503 pushes the connecting frame 1 504, the connecting frame 2 505 and the connecting frame 3 601, so that the connecting frame 4 604 on the deformed arc plate 603 rotates upward inside the rotating block 605, so that the deformed arc plate 603 and the rotating block 605 are in the same horizontal plane. At this time, the sealing top plate 606 and the circular plate 407 are in the same horizontal plane. The device has a flat surface, and a plurality of sealing top plates 606 cooperate with the circular plate 407 to seal the surface on which they are located, so that the size of the opening can be adjusted as needed when the device is in use, and it also has the function of adjusting the seal. Moreover, since the sealing top plates 606 and the circular plates 407 are arranged on the upper and lower sides, when the sealing top plate 606 on the lower side rotates, the top of the concrete in the pile body on the lower side can be squeezed to compact it, and the sealing top plate 606 on the top and the circular plate 407 form a new bottom surface, so that the pouring will not be uneven due to depression during pouring, so that the work efficiency is increased after the device is put into construction.
