Description

Technical Field

[0001] This application relates to the technical field of foundation load testing, and more particularly to a simulation device for foundation load testing. Background Technology

[0002] Load testing, as a key method for assessing the bearing capacity of foundations, is crucial for ensuring the safety of building projects. It tests the response of soil and foundation structures by applying actual or simulated loads, thus providing important data on soil stability and the rationality of foundation design. Accurate recording of load test results not only helps understand the behavior of the foundation under different conditions but also plays an irreplaceable role in optimizing design schemes and reducing engineering costs. Furthermore, this data is also an important basis for verifying the accuracy of theoretical models and numerical analyses, providing scientific assurance for subsequent building construction.

[0003] Existing soil load testing simulation devices are designed to mimic various properties of real-world soil, particularly the key parameter of density. These devices typically include a storage container in which various types of soil material can be laid and compacted to achieve the desired density. Once a suitable soil environment is obtained, simulated piles can be embedded within them. By applying pressure to the simulated piles using a jacking device, researchers can observe the changes and displacement of the simulated piles in soil with a specific density. This simulation method allows for detailed studies of different soil-foundation interactions without the need for expensive and time-consuming field tests.

[0004] However, existing foundation load testing simulation devices have significant limitations, especially in the preparation of repeated tests. After completing one test, to conduct the next test, the soil in the storage container must be completely removed, new loose soil must be laid, and then compressed to the target density. Current methods rely on manual labor or small excavation equipment for this operation, but performing such a task within the confined space of the storage container is both time-consuming and inefficient. More seriously, this approach increases the risk of accidental contact with the simulation device due to space constraints, potentially causing equipment damage and affecting the accuracy and reliability of the test results. Therefore, improving the efficiency and safety of this process is an important direction for improving existing foundation load testing simulation devices. Utility Model Content

[0005] This application provides a simulation device for foundation load testing, which solves the technical problem of difficulty in removing the storage container from the soil in existing foundation load tests, improves testing efficiency and avoids potential risks. The technical solution is as follows:

[0006] This application provides a simulation device for foundation load testing, comprising: a main body for setting up at a test site; a storage container having a first opening and being hollow inside, the first opening abutting against the main body to fasten the storage container to the main body, thereby allowing the storage container to contain soil; and a lifting mechanism disposed on the main body and connected to the storage container, the lifting mechanism being used to apply a first force to drive the storage container away from the main body, so that the soil inside the storage container is discharged through the first opening.

[0007] In one embodiment, the lifting mechanism includes: a first driving component mounted on the main body and located above the storage container; a transmission component connected to the first driving component, the first driving component driving the transmission component to rotate; a traction component wound around the transmission component and having a hook at its end; and a lifting ring on the storage container for connecting the hook, wherein the first force is a lifting force.

[0008] In one embodiment, the lifting mechanism includes: a second drive component mounted on the main body and located below the storage container; the second drive component has a retractable second piston rod; the storage container is provided with a lug, the second piston rod abuts against the lug, and the first force is a lifting force.

[0009] In one embodiment, it further includes: a first functional layer covering the inner wall of the storage container to increase the lubrication between the inner wall of the storage container and the soil.

[0010] In one embodiment, it further includes: a second functional layer, which is attached to the first functional layer and is used to wrap the soil in the storage container. The second functional layer cooperates with the first functional layer to drive the soil out of the first opening.

[0011] In one embodiment, the internal space of the storage container is cylindrical to form radial sides of the enclosing soil within the storage container.

[0012] In one embodiment, it further includes: a top-pressing device disposed on the main body and located above the storage container; the storage container is also provided with a second opening arranged opposite to the first opening, and the second opening corresponds to the top-pressing device; the top-pressing device can enter the interior of the storage container through the second opening to apply a second force to the soil inside the storage container.

[0013] In one embodiment, the jacking device is a jack with a retractable first piston rod that can extend into the storage container to compress the soil, and the second force is the load force applied to the soil by the first piston rod.

[0014] In one embodiment, the main body includes: a base having a bearing surface on top; a frame disposed above the base; a first opening fastened to the bearing surface; a pressing device disposed on the frame; a first drive component of the lifting mechanism disposed on the frame; or, a second drive component of the lifting mechanism disposed on the base.

[0016] Compared with existing technologies, the foundation load test simulation device proposed in the above technical solution can be stably set up on the test site, providing a reliable bearing platform for the storage container, thereby ensuring that the foundation load test can be carried out in a stable environment. The storage container has a first opening and is positioned with its bottom opening facing downwards to abut against the main body. This not only facilitates the containment of soil, but also allows the storage container to be detached from the main body by the first force applied by the lifting mechanism when soil needs to be replaced or removed. The soil then naturally flows out from the first opening due to gravity, greatly improving the efficiency of soil replacement. This design avoids the problem of requiring manual labor or small excavation equipment to operate in confined spaces, which not only saves a lot of manpower and resources, but also reduces the risk of equipment damage due to improper operation. Therefore, the foundation load test simulation device proposed in this patent application effectively solves the problems of low efficiency and potential risks in existing technologies, providing a more efficient and safer operating method, which is of great significance for improving the preparation and execution process of foundation load tests.

[0034] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0035] Reference Figures 1 to 4As shown, an embodiment of this application proposes a simulation device for foundation load testing. The simulation device may include: a main body 1 for setting up at the test site; a storage container 2, which has a first opening 21 and is hollow inside, the first opening 21 abutting against the main body 1 to fasten the storage container 2 onto the main body 1, so that the storage container 2 can contain soil; and a lifting mechanism 4, which is disposed on the main body 1 and connected to the storage container 2. The lifting mechanism 4 is used to apply a first force to drive the storage container 2 away from the main body 1 so that the soil in the storage container 2 is discharged through the first opening 21.

[0036] Specifically, in the technical solution adopted in this application, the main body 1 can be set up in the test site to support the storage container 2, thereby conducting foundation load tests on the main body 1. To address the problem of difficulty in removing soil from the storage container 2, the storage container 2 in this embodiment must include at least a first opening 21, which can be located at the bottom of the storage container 2. The storage container 2 is then placed on the main body 1 with the first opening 21 facing downwards. The structure of the main body 1 abuts against the outer edge of the first opening 21 of the storage container 2. With the cooperation of the main body 1, the storage container 2 can accommodate soil. The lifting mechanism 4 located above is connected to the storage container 2. When it is necessary to replace or remove the soil from the storage container 2, the lifting mechanism 4 can be operated to drive the storage container 2 away from the main body 1. Specifically, the main body 1 is disengaged by locking the container at the first opening 21, allowing the soil inside the storage container 2 to be discharged through the first opening 21 due to gravity. This effectively improves the efficiency of replacing or removing soil from the storage container 2 and saves a significant amount of manpower and resources.

[0037] Furthermore, refer to Figure 1 and Figure 2 As shown, in some embodiments, the lifting mechanism 4 includes: a first driving component 41a, mounted on the main body 1 and located above the storage container 2; a transmission component 42a, connected to the first driving component 41a, the first driving component 41a driving the transmission component 42a to rotate; a traction component 43, wrapped around the transmission component 42a, and a hook 44 is provided at the end of the traction component 43; the storage container 2 is provided with a lifting ring 23 for connecting the hook 44, and the first force is a lifting force.

[0038] Specifically, in the first embodiment of the lifting mechanism 4 adopted in this application, the lifting mechanism 4 can be an electric crane and may include: a first drive component 41a, specifically a drive motor mounted on the main body 1; a transmission component 42a, specifically a drum connected to the output shaft of the drive motor, with a spiral groove on the outer periphery of the drum; and a traction component 43, specifically a wire rope wound around the drum through the spiral groove, with a hook 44 disposed at the outer end of the wire rope. The storage container 2 is provided with a lifting ring 23 adapted to the hook 44. When it is necessary to replace or only remove the soil in the storage container 2, the hook 44 is inserted into the lifting ring 23, and the first drive component 41a is activated to drive the transmission component 42a to rotate, so that the traction component 43 is wound around the outer periphery of the transmission component 42a, thereby lifting the storage container 2 away from the main body 1. In order to enable the storage container 2 to be lifted smoothly based on the main body 1, two electric cranes can be configured in the simulation device for the foundation load test. The two electric cranes are arranged at intervals according to the diameter of the storage container 2, and the number of lifting rings 23 on the storage container 2 is also increased to two, corresponding to the number of electric cranes. The two lifting rings 23 are arranged opposite to each other on the storage container 2, so that the lifting force can be evenly distributed on the storage container 2.

[0039] Furthermore, refer to Figure 3 and Figure 4 As shown, in some embodiments, the lifting mechanism 4 includes: a second drive component 41b, mounted on the main body 1 and located below the storage container 2; the second drive component 41b has a retractable second piston rod 42b; the storage container 2 is provided with a lug 24, the second piston rod 42b abuts against the lug 24, and the first force is a lifting force.

[0040] Specifically, in the second embodiment of the lifting mechanism 4 in this application, the lifting mechanism 4 can also be a jacking device, which can also drive the storage container 2 to detach from the main body 1. Specifically, a second driving component 41b is provided below the main body 1 and the storage container 2. Unlike the first driving component 41a, the second driving component 41b can be a driving cylinder or a jack. The second driving component 41b has a retractable second piston rod 42b, which can abut against the bottom of the storage container 2. Specifically, a lug 24 for supporting the second piston rod 42b is provided on the outer surface of the storage container 2. When it is necessary to replace or simply remove the soil in the storage container 2, the second driving component 41b is activated to drive the second piston rod 42b to extend, so as to abut against the lug 24 and drive the storage container 2 to detach from the main body 1. To ensure the smooth lifting of the storage container 2 from the main body 1, two or more lifting devices can be configured in the foundation load test simulation device. Each lifting device is arranged in a one-to-one correspondence with the lugs 24 evenly distributed along the circumference of the storage container 2, so as to stably lift the storage container 2 away from the main body 1, thereby ensuring that the lifting force is evenly distributed on the storage container 2. In this embodiment, to further stabilize the connection between the lifting devices and the storage container 2, the second piston rod 42b can be fixedly connected to the corresponding lug 24. For example, the second piston rod 42b can be fixedly connected to the corresponding lug 24 by welding, or the second piston rod 42b can be detachably installed on the corresponding lug 24 using fasteners, thereby preventing the storage container 2 from sliding off the control of the lifting devices.

[0041] Where there are no significant limitations at the test site, the lifting mechanism 4 can be preferentially positioned above the storage container 2. Since the storage container 2 has a first opening 21 at its bottom for discharging soil, if the lifting mechanism 4 is positioned below the storage container 2, over time, the soil discharged from the storage container 2 may interfere with the normal operation of the lifting mechanism 4. However, if there is insufficient space above the test site, it may be impossible to position the lifting mechanism 4 above the storage container 2. In this case, the lifting mechanism 4 can be positioned below the storage container 2, using a lifting method to detach the storage container 2 from the main body 1, thus allowing the soil to be discharged through the first opening 21.

[0042] Furthermore, in some embodiments, it also includes: a first functional layer covering the inner wall of the storage container 2 for increasing the lubricity of the inner wall of the storage container 2.

[0043] Specifically, in the technical solution adopted in this application, the first functional layer can be a petroleum jelly coating. Before laying soil in the storage container 2, the petroleum jelly coating can be applied to the inner wall of the storage container 2, thereby effectively reducing the amount of soil adhering to the inner wall of the storage container 2 and improving the efficiency of removing soil from the storage container 2.

[0044] Furthermore, in some embodiments, it also includes: a second functional layer, which is attached to the first functional layer and is used to wrap the soil in the storage container 2. The second functional layer cooperates with the first functional layer to drive the soil out of the first opening 21.

[0045] Specifically, in the technical solution adopted in this application, the second functional layer can be a plastic film. Before laying soil in the storage container 2, the petroleum jelly coating can be applied to the inner wall of the storage container 2, and the plastic film can be attached to the inner wall with the petroleum jelly coating, thereby almost completely preventing soil from adhering to the inner wall of the storage container 2.

[0046] Furthermore, refer to Figures 1 to 4 As shown, in some embodiments, the internal space of the storage container 2 is cylindrical to form a radial side of the enclosing soil within the storage container 2.

[0047] Specifically, in the technical solution adopted in this application, the radial side of the storage container 2 can apply a more uniform reaction force to the soil, so that the soil in the storage container 2 can more closely resemble naturally formed or subsequently processed soil. It should be explained that, due to experimental requirements, the soil in the storage container 2 needs to be compacted using equipment such as a rammer to achieve the required density. During the compaction process, the soil is compressed, applying stress to the sidewall of the storage container 2. Simultaneously, the sidewall of the storage container 2 also applies opposite stress to the soil, causing a change in the soil's density. If the sidewall of the storage container 2 is the radial side in this embodiment, that is, the arc-shaped side, the stress applied to the radial side of the storage container 2 and the stress applied to the soil can be more uniform, thereby significantly improving the overall density quality of the soil. It is also important to note that traditional storage containers 2 are mostly rectangular. Because the inner walls of a rectangular storage container 2 have included angles, the stress exerted by the soil on the storage container 2 is uneven. During the adjustment of soil compaction, the storage container 2 cannot withstand the uneven stress and is prone to damage, affecting the progress of the experiment. Therefore, traditional rectangular storage containers 2 have strict stress-bearing requirements, and the materials used to manufacture them have high rigidity and toughness, making them very expensive. However, by using a cylindrical storage container 2, the stress exerted by the soil on the storage container 2 is more uniform, thus reducing the quality requirements for the storage container 2. This allows for the replacement of these more expensive materials, saving on the manufacturing and experimental costs of the simulation device.

[0048] Furthermore, refer to Figure 1 and Figure 3 As shown, in some embodiments, it further includes: a top-pressing device 3, disposed on the main body 1 and located above the storage container 2; the storage container 2 is also provided with a second opening 22 arranged opposite to the first opening 21, and the second opening 22 corresponds to the top-pressing device 3; the top-pressing device 3 can enter the interior of the storage container 2 through the second opening 22 to apply a second force to the soil inside the storage container 2.

[0049] Furthermore, in some embodiments, the top-pressing device 3 is a jack with a retractable first piston rod 31. The first piston rod 31 can extend into the storage container 2 to compress the soil, and the second force is the load force applied to the soil by the first piston rod.

[0050] Specifically, in the technical solution adopted in this application, in order to enable the simulation device to conduct load tests on the foundation of the soil simulated in the storage container 2, the simulation device also includes a jacking device 3, specifically a jack installed on the main body 1, located above the storage container 2; and the storage container 2 is provided with a second opening 22, which is arranged opposite to the first opening 21, so that the second opening 22 can face the jacking device 3, thereby facilitating the alignment of the first piston rod 31 of the jack with the second opening 22. When conducting a load test on the land, the first piston rod 31 can extend into the storage container 2 through the second opening 22 to compress the soil, thereby realizing the load test on the soil in the storage container 2.

[0051] Furthermore, refer to Figures 1 to 4 As shown, in some embodiments, the main body 1 includes: a base 11 with a bearing surface 111 on top; and a frame 12 disposed above the base 11.

[0052] The first opening 21 is fastened to the bearing surface 111; the top pressing device 3 is disposed on the frame 12; the first driving component 41a in the lifting mechanism 4 is disposed on the frame 12; or, the second driving component 41b in the lifting mechanism 4 is disposed on the base 11.

[0053] Specifically, in the technical solution adopted in this application, in order to achieve a height difference between the top pressure device 3 and / or the lifting mechanism 4 and the storage container 2, the main body 1 may include a base 11 and a frame 12 set on the base 11. The base 11 may be supported by reinforced concrete for laying in the test site. On the side of the base 11 away from the test site, there is a bearing surface 111 with a certain degree of flatness. The first opening 21 of the storage container 2 can be fastened to the bearing surface 111. When the tight fit is achieved, the soil required for the test can be contained through the storage container 2. Specifically, the soil can be transported into the interior of the storage container 2 through the second opening 22. The frame 12 can be set up on the test site. If the test site is to be protected from serious damage, the frame 12 can also be set up on the base 11. The part of the frame 12 that can be equipped with functional equipment is located above the base 11. When the top pressing device 3 and the electric crane are installed on the frame 12, a height difference can be formed with the storage container 2, so that the top pressing device 3 and the electric crane are set above the storage container 2.

[0054] Furthermore, refer to Figure 5 As shown, in some embodiments, the frame 12 includes: two columns 121, one end of which is provided with a mounting part, and the two columns 121 are arranged at intervals on the bearing surface 111 through the mounting parts; and a crossbeam 122 connected to the end of the two columns 121 away from the base 11.

[0055] Storage container 2 is located between two columns 121, with the second opening 22 facing the crossbeam 122; pressing device 3 is installed on the crossbeam 122, with the pressing device 3 located between the two columns 121 corresponding to the second opening 22; first driving component 41a is installed on the crossbeam 122, with the first driving component 41a located between the two columns 121; or, second driving component 41b, configured on the base 11, is located between the two columns 121.

[0056] Specifically, in the preferred embodiment of the technical solution adopted in this application, the frame 12 is erected on the base 11. The frame 12 includes at least two spaced columns 121, both of which are fixed to the base 11 by mounting portions at their ends. The mounting portions can be bosses adapted to the flatness of the base 11, and the bosses are provided with mounting holes, through which anchor bolts are driven into the base 11. A crossbeam 122 is connected to the end of the two columns 121 away from the base 11. Since the two columns 121 are spaced apart, the crossbeam 122 can be used to install the jacking device 3 and the electric crane, and the storage container 2 can also be located between the two columns 121 to realize load simulation tests and to remove the storage container 2 from the base 11 and out of the soil by the lifting mechanism 4.
