Description

Technical Field

[0001] This utility model relates to the field of vibration technology, specifically to a vibration component and a high-frequency vibration curing device for soft substrates. Background Technology

[0002] In existing highway construction, weak base soil is often encountered. This type of soil has characteristics such as large quantity, high water content, large void ratio, low permeability, high compressibility, low shear strength and bearing capacity.

[0003] To achieve the separation of water and soil in soft soil foundations, existing technologies typically employ dredging and replacement or vacuum preloading during construction. However, dredging and replacement involves large-scale excavation and is costly, while vacuum preloading requires specialized equipment and has a long construction period, neither of which can quickly achieve the separation of water and soil in soft soil foundations.

[0004] Therefore, there is an urgent need for a new technology for water and soil separation with controllable cost. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention aims to provide a vibration component and a high-frequency vibration solidification device for soft soil foundations. By employing this solution, water and soil can be separated sequentially in the silt layer and soil layer using an extended vibration rod at a specific vibration frequency and with a specific arrangement of the vibration rod, thereby achieving efficient and economical soft soil foundation treatment.

[0006] This utility model is achieved through the following technical solution:

[0007] A vibration assembly, comprising:

[0008] At least one vibrating rod for series connection, wherein the two ends of the vibrating rod are respectively provided with a first internal thread groove and a first external thread section, and a first electrode interface that can be electrically connected by contact is provided between the bottom side of the first internal thread groove and the top end of the first external thread section; the first electrode interface is used to rotate the centrifugal rotor inside the vibrating rod.

[0009] An insulating protective sleeve is connected to the end of the vibrating rod and is used to enclose the first internal thread groove or the first external thread section of the end of the vibrating rod.

[0010] Compared to existing technologies that cannot quickly separate water and soil in soft foundation soils characterized by large reserves, high water content, high porosity, low permeability, high compressibility, and low shear strength and bearing capacity, this invention provides a vibration assembly. This solution uses elongated vibrating rods to sequentially separate water and soil in silt and soil layers at specific vibration frequencies and with appropriate rod arrangements, achieving efficient and economical soft soil foundation treatment. Specifically, the solution includes at least one vibrating rod connected in series. Each vibrating rod has a first internal threaded groove and a first external threaded section at both ends, allowing several vibrating rods to be connected in series to extend their length. The vibrating rod used in this solution is an eccentric vibrating rod, containing a motor, a centrifugal rotor, and an eccentric shaft. The motor controls the centrifugal rotor to drive the eccentric shaft, thus vibrating the rod. The motor's operation and speed adjustment can be intelligently controlled, all existing technologies, and will not be elaborated upon here. This solution addresses the limitations of existing eccentric vibratory rods by providing first electrode interfaces on both the bottom side of the first internal threaded groove and the top of the first external threaded section. The first electrode interface on the bottom side of the first internal threaded groove is connected to the motor power supply inside the vibratory rod via an internal wire, and is also connected in parallel with the first electrode interface on the bottom first external threaded section via the same internal wire, facilitating power connection to the next vibratory rod. The topmost vibratory rod is powered by an external power supply and the control platform equipment. During use, an insulating protective sleeve can be used to seal the bottommost end of the vibratory assembly to prevent leakage.

[0011] In practical applications, due to the complex composition of silt, consisting of particles of varying sizes and exhibiting a significant hierarchical distribution, it presents a layered structure transitioning from silt to clay from top to bottom. This multiphase composite system contains 30-70% pore water, with organic matter and clay forming a colloidal structure. Therefore, after inserting a vibratory rod, the weak base soil becomes unevenly distributed due to differences in physical properties (such as density, particle size, and flowability). Vibration can disrupt the adsorption forces between soil particles, causing them to rearrange and form a denser structure, thereby accelerating water drainage. This leads to stratification of the material structure. Initially, silt and organic matter form a dense impermeable layer. After vibration, heavier particles sink, while the lighter mixture of organic matter and water floats to the top. Continued vibration in the later stages disrupts the soil layer structure, allowing water to flow through the gaps between particles to the bottom layer. Changes in the pore water pressure distribution in the soil promote water flow and drainage, thus accelerating foundation consolidation. The extended vibrating rod provided by this utility model can first be operated to stir and vibrate the surface of the silt over a large area, causing turbid mud water to be separated from the surface. Then, the water is pumped out a second time to reduce the water content of the silt to below 30%. Subsequently, the vibrating rod is extended so that it can be connected into a long rod and driven deep into the soil. Through continuous vibration, the soil particles are arranged more compactly, and water is more easily discharged. Finally, the soil forms a plastic mud block that meets the load-bearing requirements.

[0012] In a further step, to achieve a closed connection, one end of the insulating protective sleeve has a second internal thread groove, which is used to adapt and connect with the first external thread section.

[0013] Both the bottom surface of the first internal thread groove and the end face of the first external thread section are covered with an insulating rubber layer; channels for the first electrode interface to extend are provided on the insulating rubber layers on both the bottom surface of the first internal thread groove and the end face of the first external thread section. In this design, insulation is achieved by setting an insulating rubber layer, such as a rubber gasket. The insulating rubber layer is elastic and slightly higher than the first electrode interface. After the first external thread section and the first internal thread groove are connected in place, the corresponding first electrode interface is just connected and energized, and the insulating rubber layer is compressed relative to it, sealing and isolating the electrode interface from the external environment. In addition, a sealing ring can be set at the end of the second internal thread groove of the insulating protective sleeve to form a seal. The insulating protective sleeve has a certain degree of hardness and can withstand impacts with hard objects in the soil; the vibrating rod is fully sealed with a waterproof rating of IP68.

[0014] In a further improvement, to facilitate the insertion of the vibrating rod, the other end of the insulating protective sleeve is spherical.

[0015] A further improvement is that, to facilitate real-time monitoring of the moisture content of each soil layer, the outer wall of the vibrating rod is equipped with a soil moisture sensor.

[0016] A further solution, to facilitate graded control based on the humidity of each layer, also includes a control terminal. This control terminal is used to independently control the operation of the motor inside a specific vibrating rod based on the signal from the soil moisture sensor on that rod. In this solution, when the soil moisture sensor on a particular vibrating rod detects that the nearby soil moisture has decreased to a certain threshold, the motor inside that rod can be controlled to reduce its speed or stop completely based on the feedback signal, thereby reducing the vibration frequency and saving electricity. Since the soil moisture typically increases from top to bottom during the vibration process across different soil layers, the vibration frequency and soil moisture of the vibrating rod will generally increase accordingly from top to bottom during the later stages of construction.

[0017] Furthermore, this invention also provides a device for mass-arraying vibrating rods, including a base with a plurality of vibrating components evenly spaced on the bottom surface of the base. By connecting a plurality of vibrating components in parallel on the base, the separation efficiency can be improved by increasing the vibrating rod area per unit area.

[0018] As a further alternative, as an optional arrangement, several of the vibration components are arranged in a rectangular or circular array on the bottom surface of the base.

[0019] A further solution, as a detachable connection method, is to have several joints evenly distributed at intervals on the bottom surface of the base, and the outer wall of each joint has a second external thread section that matches the first internal thread groove.

[0020] In a further step, to achieve electrical connection, the connector also has a second electrode interface on its end face. This second electrode interface can achieve electrical connection by contacting the first electrode interface. Each connector can also be connected to an external power supply device or control platform via a power cord.

[0021] A further improvement, to facilitate controllable operation of the entire high-frequency vibration solidification soft soil foundation device in soft base soil via excavator control, includes two opposing lugs on the top surface of the base. These lugs form a bucket linkage structure with the excavator's connecting end. In this design, the two opposing lugs on the base can be hinged to the excavator's boom, connecting rod, and rocker arm, thereby controlling the vibration direction and depth.

[0022] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0023] 1. This utility model provides a vibration component and a high-frequency vibration curing device for soft soil. By using this solution, water and soil can be separated sequentially in the silt layer and soil layer by means of an extended vibrating rod, with a specific vibration frequency and vibrator arrangement, thereby achieving efficient and economical soft soil foundation treatment.

[0024] 2. This utility model provides a vibration component and a high-frequency vibration solidification soft soil device. First, the vibrating rods are operated to agitate and vibrate the surface of the silt over a wide area, causing turbid mud and water to precipitate from the surface. A second pumping process is then performed to reduce the silt's moisture content to below 30%. Subsequently, by connecting and lengthening multiple solidification soft soil devices in series, several vibrating rods are driven deep into the soil in a grid pattern. Through continuous vibration, the soil particles are more compacted, and water is more easily drained, ultimately forming a plastic mud block that meets load-bearing requirements.

Detailed Implementation

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0035] Example 1:

[0036] This embodiment 1 provides a vibration component, such as... Figures 1-3 As shown, it includes:

[0037] At least one vibrating rod 1 for series connection, the two ends of the vibrating rod 1 are respectively equipped with a first internal thread groove and a first external thread section 14, and a first electrode interface 13 that can be electrically connected by contact is provided between the bottom side of the first internal thread groove and the top end of the first external thread section 14; the first electrode interface 13 is used to rotate the centrifugal rotor inside the vibrating rod 1.

[0038] An insulating protective sleeve 12 is connected to the end of the vibrating rod 1 and is used to enclose the first internal thread groove or the first external thread section 14 of the end of the vibrating rod 1.

[0039] Compared to existing technologies that cannot quickly separate water and soil in soft foundation soils characterized by large volume, high water content, high porosity, low permeability, high compressibility, and low shear strength and bearing capacity, this invention provides a vibration assembly. This solution utilizes an extended vibrating rod 1 to sequentially separate water and soil in the silt and soil layers at a specific vibration frequency and arrangement, achieving efficient and economical soft soil foundation treatment. Specifically, the assembly includes at least one vibrating rod 1 connected in series. Each vibrating rod 1 has a first internal threaded groove and a first external threaded section 14 at both ends, allowing multiple vibrating rods 1 to be connected in series to extend their length. The vibrating rod 1 used in this solution is an eccentric vibrating rod 1, containing a motor, a centrifugal rotor, and an eccentric shaft. The motor controls the centrifugal rotor to drive the eccentric shaft, thus vibrating the vibrating rod 1. The motor's operation and speed adjustment are intelligently controlled, all existing technologies, and will not be elaborated upon here. This solution addresses the existing eccentric vibrating rod 1 by providing a first electrode interface 13 on both the bottom side of the first internal thread groove and the top of the first external thread section 14. The first electrode interface 13 on the bottom side of the first internal thread groove is connected to the motor power supply inside the vibrating rod 1 via an internal wire, and is also connected in parallel with the first electrode interface 13 on the bottom first external thread section 14 via the internal wire, facilitating power connection with the next vibrating rod 1. The topmost vibrating rod 1 is powered by an external power supply and the control platform equipment. During use, the bottommost end of the vibrating assembly can be insulated and sealed with an insulating protective sleeve 12 to prevent leakage.

[0040] In addition, to prevent the vibration connection of the vibrating rod 1 from loosening, a spring washer is added at the connection point. During installation, tighten the vibrating rod 1 until the spring washer is completely flattened. After being flattened, it generates a continuous elastic force, maintaining the friction between the connection points of the vibrating rod 1 at both ends of the thread and preventing loosening.

[0041] In practical applications, due to the complex composition of silt, consisting of particles of varying sizes and exhibiting a significant hierarchical distribution, it presents a layered structure transitioning from silt to clay from top to bottom. This multiphase composite system contains 30-70% pore water, with organic matter and clay forming a colloidal structure. Therefore, after the insertion of vibrating rod 1, the weak base soil becomes unevenly distributed due to differences in physical properties (such as density, particle size, and flowability). Vibration can disrupt the adsorption forces between soil particles, causing them to rearrange and form a denser structure, thereby accelerating water drainage. This leads to stratification of the material structure. Initially, silt and organic matter form a dense impermeable layer. After vibration by vibrating rod 1, heavier particles sink, while the lighter mixture of organic matter and water floats to the top. Continuous vibration in the later stages disrupts the soil layer structure, allowing water to flow through the gaps between particles to the bottom layer. Changes in the pore water pressure distribution in the soil promote water flow and drainage, thereby accelerating foundation consolidation. The extended vibrating rod 1 provided by this utility model can first be operated to stir and vibrate the surface of the silt over a large area, causing turbid mud water to be separated from the surface. Then, the water is pumped out a second time to reduce the water content of the silt to below 30%. Subsequently, the vibrating rod 1 is extended to form a long rod that is driven deep into the soil. Through continuous vibration, the soil particles are arranged more compactly, and water is more easily discharged. Finally, the soil forms a plastic mud block that meets the load-bearing requirements.

[0042] In some embodiments, to achieve a closed connection, one end of the insulating protective sleeve 12 has a second internal thread groove 15, which is used to adapt and connect with the first external thread section 14.

[0043] Both the bottom surface of the first internal thread groove and the end face of the first external thread section 14 are provided with an insulating rubber layer 16; channels for the first electrode interface 13 to extend are provided on the insulating rubber layer 16 on the bottom surface of the first internal thread groove and the end face of the first external thread section 14. In this solution, insulation is achieved by setting the insulating rubber layer 16, such as a rubber gasket. The insulating rubber layer 16 is elastic and slightly higher than the first electrode interface 13. After the first external thread section 14 and the first internal thread groove are connected in place, the corresponding first electrode interface 13 is just connected and energized, and the insulating rubber layer 16 is squeezed relative to it, sealing and isolating the electrode interface from the external environment. In addition, a sealing ring can be set at the end of the second internal thread groove 15 of the insulating protective sleeve 12 to form a seal. Its insulating protective sleeve 12 has a certain hardness and can withstand impacts with hard objects in the soil; the vibrating rod 1 is fully sealed with a waterproof rating of IP68.

[0044] In some embodiments, the other end of the insulating protective sleeve 12 is spherical to facilitate the insertion of the vibrating rod 1.

[0045] In some embodiments, a soil moisture sensor 11 is provided on the outer wall of the vibrating rod 1 to facilitate real-time monitoring of the moisture content of each soil layer.

[0046] In some embodiments, to facilitate graded control based on the humidity of each layer, a control terminal is also included. This control terminal is used to independently control the operation of the motor inside a specific vibrating rod 1 based on the signal from the soil moisture sensor 11 on that vibrating rod 1. In this scheme, when the soil moisture sensor 11 on a specific vibrating rod 1 detects that the nearby soil moisture has decreased to a certain threshold, the motor inside that vibrating rod 1 can be controlled to reduce its speed or stop completely based on the feedback signal, thereby reducing the vibration frequency and saving electricity. During the vibration process in each soil layer, the soil moisture typically increases sequentially from top to bottom. Therefore, in the later stages of construction, the vibration frequency and soil moisture of the vibrating rod 1 generally increase accordingly from top to bottom.

[0047] Example 2:

[0048] This embodiment 2 also provides a high-frequency vibration curing soft substrate device, such as... Figures 4-6 As shown, it includes:

[0049] The base 2 has several vibration components evenly distributed at intervals on its bottom surface. These vibration components, connected in parallel on the base 2, can be deployed over a wide area of ​​the soil layers via a grid, improving separation efficiency.

[0050] In some embodiments, as an optional arrangement, several of the vibration components are arranged in a rectangular or circular array on the bottom surface of the base 2.

[0051] In some embodiments, as a detachable connection method, a plurality of connectors 21 are evenly distributed at intervals on the bottom surface of the base 2, and the outer wall of the connector 21 has a second external thread section that is adapted to the first internal thread groove.

[0052] In some embodiments, to enable electrical connection, the end face of the connector 21 is further provided with a second electrode interface, which can achieve electrical connection by contacting the first electrode interface 13. Each connector 21 can be connected to an external power supply device via a power cord.

[0053] In some embodiments, to facilitate controllable operation of the entire high-frequency vibration solidification soft soil foundation device in soft base soil by controlling it with an excavator, two oppositely arranged ear plates 22 are also provided on the top surface of the base 2. The two ear plates 22 can form a bucket linkage 4 structure with the excavator connection end. In this scheme, the two opposite ear plates 22 on the base 2 can be hinged to the excavator's stick 3, linkage 4, and rocker arm 5, thereby controlling its vibration direction and vibration depth.

[0054] Specific working principle:

[0055] like Figure 6As shown, taking pond silt as an example: First, the surface water is pumped out, and after the bottom silt is exposed, the pump is turned off. To ensure the safety of construction workers and prevent them from falling into the silt and causing accidents, workers can use an excavator to operate the bottom plate. One or more vibrating rods 1 can be connected in parallel on the bottom plate to agitate the silt surface over a wide area. After vibration, turbid muddy water is released from the surface, and the water is pumped out again to reduce the silt moisture content to below 30%. Then, the vibrating rods 1 are connected in series to form a long rod and driven deep into the soil. Several locations are then arranged in parallel to form a grid, supplemented by a certain number of drainage boards. These drainage boards are existing conventional plates used for water collection and drainage, ensuring that the discharged water can be collected and discharged in a timely manner. Through continuous vibration, the soil particles are made more compact, and water is more easily discharged. Finally, the soil forms plastic mud blocks that meet the load-bearing requirements.

[0056] In addition, if it is silt from a small pond, after the second pumping, the water content of the silt will be significantly reduced. If there is no leakage during the transfer process, it can be directly excavated and transported for replacement.
