Description

Technical Field

[0001] The utility model relates to the technical field of pile foundation detection, in particular to a self-balancing multi-directional detection device for pile foundations. Background Art

[0002] With the continuous development of my country's economic construction, the construction of infrastructure such as high-rise buildings, large railways, highway bridges and offshore projects is increasing. The requirements for foundation engineering design for various types of infrastructure construction are becoming increasingly higher. Pile foundations are widely used in foundation design due to their good bearing capacity and seismic performance. How to determine the bearing capacity of a single pile is a key issue faced in pile foundation design.

[0003] In actual engineering applications, on-site in-situ tests are considered to be the most reliable method for determining bearing capacity. Traditional static load tests are divided into two types: one is the pile loading method. When the measured bearing capacity is large, it will be limited by factors such as excessive transportation of piled loads and long construction time of the load-bearing platform, affecting the convenience and safety of the test; the second static load test method is the anchor pile method. The anchor pile method is difficult to control the load during installation, and multiple anchor piles and reaction beams must be set up, which is expensive and has certain risks. That is, when the bearing capacity of the foundation pile is currently tested, the operation is cumbersome, time-consuming and labor-intensive. Therefore, a self-balancing multi-directional detection device for the foundation pile is needed. Utility Model Content

[0004] The purpose of the utility model is to provide a self-balancing multi-directional detection device for pile foundations, so as to solve the problems of the existing pile foundation detection device proposed in the above background technology in that the operation is cumbersome, time-consuming and labor-intensive.

[0005] To achieve the above object, the present invention provides the following technical solution: a self-balancing multi-directional detection device for a foundation pile, comprising a foundation pile body and an external docking plate, wherein the external docking plate is fixed to the top end of the outer side of the foundation pile body;

[0006] Also includes:

[0007] The top of the foundation pile body is connected to the reference beam, and threaded holes are provided on both sides of the top of the reference beam, and fixing screws are threadedly connected inside the threaded holes, and one end of the fixing screws extends to the inside of the outer docking plate, and reference piles are fixed on both sides of the bottom end of the reference beam, and a static load tester is connected to the left side of the bottom end of the reference beam. The interior of the foundation pile body is connected to a load box, and upper displacement rods are fixed on both sides of the top of the load box, and lower displacement rods are fixed on the top of the load box between the upper displacement rods, and displacement rod casings are sleeved on the outer sides of the upper and lower displacement rods, and a high-pressure oil pipe passes through the interior of the load box, and one end of the high-pressure oil pipe extends to the outside of the foundation pile body and is connected to a pressurized oil pump, and the pressurized oil pump is arranged at the bottom end of the outer docking plate.

[0008] Preferably, the bottom ends of the reference beams are uniformly connected to magnetic bases, and the bottom ends of the magnetic bases are connected to displacement sensors, and fixing mechanisms are provided between the magnetic bases and the reference beams.

[0009] Preferably, two fixing mechanisms are provided at the bottom end of the magnetic base, and the fixing mechanisms each include a socket, and the sockets are both provided at the top end of the reference beam, and locking blocks are connected to both sides of the sockets, and plug blocks are provided inside the sockets between the locking blocks, and the plug blocks are fixed to the bottom end of the magnetic base.

[0010] Preferably, the inserting block is made of rubber, and notches are provided on both sides of the inserting block. A protrusion is provided on one side of the locking block, and the protrusion and the notch are engaged with each other.

[0011] Preferably, main ribs are fixed on both sides of the top and bottom ends of the load box, and guide ribs are welded to one side of the main ribs, and one end of the guide ribs is connected to one side of the load box.

[0012] Preferably, a support ring is sleeved on the bottom end of the outer side of the foundation pile body, and support ribs are evenly fixed to the bottom end of the support ring, and a ground cone is fixed at one end of each of the support ribs.

[0013] Preferably, four supporting ribs are provided on the supporting ring, and the supporting ribs are distributed in a ring shape on the supporting ring.

[0014] Compared with the prior art, the present invention has the following beneficial effects: the self-balancing multi-directional detection device for pile foundations is not only simple, convenient and safe to detect, but also the displacement sensor for pile foundation detection can be freely disassembled and assembled, and the operation is convenient;

[0015] Install the displacement rod casing into the main body of the pile, then pour concrete into the main body of the pile, then lead the high-pressure oil pipe out of the main body of the pile, and use the pressure oil pump to fill the load box with oil to achieve pressurization. As the oil pressure gradually increases, the load box will produce corresponding deformation, thereby applying force upward and downward to the pile body of the main body of the pile, forming a pair of balanced forces. During the loading process, displacement sensors are used to collect data such as pile displacement and load in real time. During this process, the main body of the pile can be tested in all directions, and then the bearing capacity of the main body of the pile can be accurately tested. The overall testing process is simple and safe.

Displacement rod casings are also sleeved on the upper and lower displacement rods to prevent them from being corroded and damaged by materials such as concrete and mud.

[0017] The reference beam is overlapped on the main body of the pile and fixed through the threaded hole with a fixing screw to fix the reference beam and the external docking plate. This helps to ensure that the reference beam will not be displaced or deformed by external forces during the main body of the pile inspection. The reference beam provides a horizontal reference plane, reducing the interference of external factors on the test process, thereby ensuring the reliability and accuracy of the inspection.

[0018] Insert the plug into the socket accordingly, and make the notch on the outside of the plug engage with the convex block on the outside of the socket, and then the magnetic base can be installed on the corresponding reference beam. By utilizing the mutual adsorption effect between the magnetic base and the displacement sensor, the displacement sensor can be conveniently installed on the reference beam. The magnetic base and the displacement sensor can be conveniently removed by performing the reverse operation later. During the bearing capacity test of the foundation pile body, there is no need to spend a lot of time to fix and adjust the displacement sensor, and convenient maintenance and cleaning can be carried out later to keep the displacement sensor in good working condition to ensure the accuracy of the test.
