Description

Technical Field

[0001] This utility model relates to the field of vertical compressive strength testing technology for single piles, and in particular to a device for testing the vertical compressive bearing capacity of piles. Background Technology

[0002] The bearing capacity of a single pile refers to the maximum load that a single pile can withstand under load, ensuring the strength and stability of both the foundation soil and the pile itself, while maintaining allowable deformation to guarantee the normal use of the structure. Generally, piles are subjected to axial force, transverse force, and bending moment; therefore, the axial and transverse bearing capacities of a single pile must be studied and determined separately. The bearing capacity of a pile is the result of the interaction between the pile and the soil. Understanding the basic concepts of force transmission path between the pile and soil under axial load, the compositional characteristics of single pile bearing capacity, and the failure modes of single piles under stress is crucial for correctly determining the bearing capacity of a single pile.

[0003] Patent application CN210013254U discloses a device for testing the vertical compressive bearing capacity of a single pile, comprising a frame, a hydraulic press body and a base. The outer wall of the frame is fixedly connected to two symmetrically distributed support plates. The side wall of the support plates is provided with a circular through hole, and the hole wall of the circular through hole is interactively connected to a connecting rod. The opposite ends of the two connecting rods are fixedly connected to a protective mechanism. The upper surface of the frame is fixedly connected to an actuation mechanism.

[0004] The shortcomings of the above-mentioned single pile vertical compressive bearing capacity testing device are: 1. It has a complex structure, is cumbersome to operate, and has high maintenance and repair costs; 2. It protects the debris generated by the single pile collapse with an arc-shaped protective plate, but does not have a dust suppression function. The dust generated by the single pile collapse can easily prevent personnel from observing the condition of the single pile. In order to address the above problems, we have launched a pile vertical compressive bearing capacity testing device. Utility Model Content

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0026] The pile vertical compressive bearing capacity testing equipment disclosed in this utility model is mainly used in the scenario of testing the vertical compressive strength of a single pile.

[0027] Reference Figures 1 to 5 A pile vertical compressive bearing capacity testing device includes: a testing box 1, a first box door 2 rotatably connected to one side of the testing box 1, a placement groove 3 opened at the bottom of the inner wall of the testing box 1, a hydraulic cylinder 4 installed at the top of the inner wall of the testing box 1, a pressing plate 5 fixedly connected to the bottom of the hydraulic cylinder 4, a receiving groove 6 opened inside the placement groove 3, a fixing component installed inside the receiving groove 6, a filter groove 15 opened on one side of the testing box 1, through holes 18 equidistantly opened between the bottom of the placement groove 3 and the top of the filter groove 15, a filter component installed inside the filter groove 15, a second box door 19 rotatably connected to one side of the testing box 1, and a discharge port 26 opened on one side of the testing box 1.

[0028] In the above technical solution, considering the complex structure, cumbersome operation, and high maintenance and repair costs of the detection device, while the arc-shaped protective plate protects against debris generated by the collapse of a single pile, it lacks dust suppression capabilities. The dust generated by the collapse of a single pile can easily obstruct personnel from observing the condition of that pile. To address this issue, the specific operation is as follows: The pile is placed in the placement groove 3 and then fixed using a fixing component. The hydraulic cylinder 4 is then activated to move the pressing plate 5 downwards, pressing the pile to test its compressive strength. When the pile collapses, the filter component draws dust and impurities into the filter tank 15 for filtration, and the impurity particles are discharged from the outlet 26. The fixing component prevents the pile from shifting during the detection process, ensuring the pile remains in the optimal detection position, thus improving the accuracy and reliability of the detection. The filter component effectively adsorbs and captures dust and impurities generated during pile collapse, reducing dust concentration in the working area and facilitating observation by personnel.

[0029] Reference Figures 1 to 5In a preferred embodiment, the fixing assembly includes two lead screws 7, which are rotatably connected inside the receiving groove 6. Two mounting plates 8 are threaded to the outer side of the lead screws 7, and a clamping plate 9 is fixedly connected to one side of each mounting plate 8. A placement plate 28 is fixedly connected to one side of the detection box 1. A first motor 10 is provided on the top of the placement plate 28. A first gear 11 is fixedly connected to the outer side of the output shaft of the first motor 10. A second gear 12 is fixedly connected to the outer side of one of the lead screws 7, and the first gear 11 and the second gear 12 mesh. A pulley 13 is fixedly connected to the outer side of the lead screw 7, and a belt 14 is provided inside the pulley 13.

[0030] In the above technical solution, considering the problem of pile body shifting during compressive strength testing, which affects the testing, the specific operation is as follows: The pile body is placed in the placement groove 3, and then the first motor 10 is started to drive the first gear 11 to rotate. Utilizing the meshing relationship between the first gear 11 and the second gear 12, the second gear 12 and one of the lead screws 7 are further driven to rotate. Then, using the action of the pulley 13 and the belt 14, the two lead screws 7 are driven to rotate simultaneously, thereby driving the mounting plate 8 to move, so that the clamping plates 9 move closer to each other and clamp and fix the pile body from the placement groove 3. This reduces the risk of the pile body accidentally sliding or falling off during the test. At the same time, it can be adjusted according to pile bodies of different sizes, making it more flexible to adapt to different testing needs.

[0031] Reference Figures 1 to 5 In a preferred embodiment, the filter assembly includes a fixing plate 20, which is fixedly connected to the inside of the filter tank 15 at equal intervals. A filter screen 21 is slidably connected inside the filter tank 15. A connecting rod 22 is equidistantly arranged between the top and bottom of the fixing plate 20, and a spring 23 is arranged on the outside of the connecting rod 22. An exhaust fan 16 is arranged at the bottom of the inner wall of the filter tank 15, and a connecting pipe 17 is fixedly connected to one end of the exhaust fan 16. A second motor 25 is arranged on one side of the detection box 1, and one end of the output shaft of the second motor 25 extends into the inside of the filter tank 15 and is fixedly connected to a cam 24.

[0032] In the above technical solution, considering that the device protects against debris generated by the collapse of a single pile through an arc-shaped protective plate, but does not have a dust suppression function, the dust generated by the collapse of a single pile can easily prevent personnel from observing the condition of the single pile. To solve this problem, the specific operation is as follows: When a single pile collapses, the exhaust fan 16 is started to suck the dust into the filter tank 15, and then the filter screen 21 is used for filtration to isolate the impurities and debris on the filter screen 21. The filtered air is then discharged from the connecting pipe 17. Then, the second motor 25 is started to drive the cam 24 to rotate. The cam 24 pushes against the filter screen 21, and through the setting of the connecting rod 22 and the spring 23, the filter screen 21 can vibrate, shaking the impurities and debris on the surface to one side. Finally, it is discharged from the discharge port 26. By eliminating the interfering factors caused by dust, the operator can better observe and judge the condition of the pile, and improve the reliability and accuracy of the compressive strength test results.

[0033] Reference Figures 1 to 5 In a preferred embodiment, the first door 2 is provided with an observation window 27 inside; the observation window 27 allows the operator to observe the condition of the pile and the testing process in real time when conducting pile compressive strength testing, without having to open the equipment, thus improving the safety of the work.

[0034] Working principle: In use, the pile is placed in the placement groove 3, and then the first motor 10 is started to drive the first gear 11 to rotate. Utilizing the meshing relationship between the first gear 11 and the second gear 12, the second gear 12 and one of the lead screws 7 are further driven to rotate. Then, using the action of the pulley 13 and the belt 14, both lead screws 7 rotate simultaneously, thereby moving the mounting plate 8, causing the clamping plates 9 to move closer together and clamp the pile in place 3. Then, the hydraulic cylinder 4 is activated to move the pressing plate 5 downwards, pressing the pile to test its compressive strength. When the pile collapses... When interrupted, the exhaust fan 16 is started to draw dust into the filter tank 15, and then the filter screen 21 is used for filtration to isolate impurities and debris on the filter screen 21. The filtered air is then discharged from the connecting pipe 17. Then, the second motor 25 is started to drive the cam 24 to rotate. The cam 24 pushes against the filter screen 21, and the filter screen 21 can be vibrated by the connecting rod 22 and the spring 23, which shakes the impurities and debris on the surface to one side. Finally, it is discharged from the discharge port 26. All contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0035] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
