Description

Technical Field

[0001] This utility model relates to the field of consolidation technology, specifically a dual-drainage remolded soft soil consolidation device. Background Technology

[0002] A consolidation apparatus is an engineering device used to accelerate the drainage and consolidation of soil, silt, or other loose materials. It removes moisture from the material through mechanical pressure or vacuum negative pressure, thereby improving the material's density and load-bearing capacity.

[0003] In the actual use of existing consolidation apparatuses, after the consolidation operation is completed, the sample needs to be removed from the consolidation cylinder. Currently, there are two methods for soil sampling. One method is to manually lift and invert the entire consolidation cylinder and use external force to press the sample out. During this process, the operator needs to manually hold the consolidation cylinder for a long time (especially in large-sized or fully loaded conditions), resulting in high labor intensity and low work efficiency. The other method is to use temporary supports for auxiliary support, but the supports lack a fixed connection with the consolidation apparatus, which can easily cause the consolidation cylinder to slip due to vibration or displacement, resulting in sample damage or even equipment safety hazards. Therefore, a dual-drainage remolded soft soil consolidation apparatus is proposed to solve the above problems. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a dual-drainage reconstituted soft soil consolidation apparatus. This apparatus allows the consolidation cylinder to be moved onto a sampling frame for convenient sample collection, and enables rapid water drainage via a dual-drainage system. This solves the problem of sample removal from the consolidation cylinder after consolidation, a process currently employed by existing consolidation apparatuses. Two methods exist: one involves manually lifting and inverting the consolidation cylinder, applying external force to extract the sample. This requires prolonged manual support (especially for large or fully loaded cylinders), leading to high labor intensity and low efficiency. The other method uses temporary supports, but these lack a fixed connection to the consolidation apparatus, making the consolidation cylinder prone to slippage due to vibration or displacement, potentially causing sample damage or even equipment safety hazards.

[0006] (II) Technical Solution

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A dual-drainage reconstituted soft soil consolidation device includes a consolidation device body, a base and a consolidation cylinder installed on the surface of the consolidation device body, the consolidation cylinder being movably connected to the surface of the base, a spliced ​​pressing component extending to the inner side of the consolidation cylinder being provided on the outer side of the consolidation device body, two vertically arranged bearing columns being symmetrically fixedly installed on the surface of the consolidation device body, and a limiting frame being fixedly connected to the top of each of the two bearing columns, a detachable support component being provided on the outer side of the limiting frame, a first drainage pipe for draining filtered water being connected to the outer side of the base, and a second drainage pipe being provided above the spliced ​​pressing component.

[0008] The beneficial effects of this utility model are:

[0009] This dual-drainage remolded soft soil consolidation apparatus has the advantages of being able to move the consolidation cylinder onto the sampling frame for convenient sample collection, and being able to quickly drain water through a dual-drainage method.

[0010] Based on the above technical solution, the present invention can be further improved as follows.

[0011] Furthermore, the consolidation apparatus body includes a base plate, support rods, a pressure box, and a pressure rod. At least two support rods are vertically fixed on the upper surface of the base plate. The pressure box is fixedly connected to the top of the support rods. The pressure rod can be vertically moved through the top of the pressure box, and the lower end of the pressure rod is fixedly connected to the top of the spliced ​​pressing assembly.

[0012] Furthermore, filter sheets are respectively provided on the upper surface of the base and the lower surface of the spliced ​​pressing assembly. The longitudinal section of the base has a stepped structure, and the diameter of its upper step matches the inner diameter of the bottom of the consolidation cylinder.

[0013] The beneficial effect of adopting the above-mentioned further solution is that the filter can allow water to overflow from the experimental soil during the pressurization process.

[0014] Furthermore, the splicing pressing assembly includes at least two detachably connected splicing rods and pressing plates. Each splicing rod includes a main rod body, with an external threaded rod at the lower end and an internal threaded groove on the inner side that mates with the external threaded rod. The bottom end of the lowest splicing rod is fixedly connected to a pressing plate, and the top end of the highest splicing rod is fixedly connected to the lower end of the pressure rod. The diameter of the pressing plate matches the inner diameter of the consolidation cylinder.

[0015] The advantage of adopting the above-mentioned further scheme is that the spliced ​​pressing component can perform consolidation operations on the experimental soil.

[0016] Furthermore, the support assembly includes a horizontally arranged support base plate, a first pressure plate and a second pressure plate symmetrically arranged on both sides of the support base plate. The support base plate slides against the outside of the limiting frame through the first pressure plate and the second pressure plate. A discharge hole is provided at the top of the support base plate.

[0017] The advantage of adopting the above-mentioned further solution is that the support assembly can support the consolidated cylinder.

[0018] Furthermore, the bottom of the consolidation apparatus body is provided with four support legs arranged in a rectangular array, and the two bearing columns are symmetrically distributed on the outside of the consolidation cylinder. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] In the embodiments, by Figure 1-4The present invention discloses a dual-drainage remodeling soft soil consolidation device, comprising a consolidation device body 1, a base 2 and a consolidation cylinder 3 mounted on the surface of the consolidation device body 1, the consolidation cylinder 3 being movably connected to the surface of the base 2, a spliced ​​pressing component 4 extending to the inner side of the consolidation cylinder 3 being provided on the outer side of the consolidation device body 1, two vertically arranged bearing columns 11 being symmetrically fixedly installed on the surface of the consolidation device body 1, the top of each of the two bearing columns 11 being fixedly connected to a limiting frame 5, a detachable support component 6 being provided on the outer side of the limiting frame 5, a first drain pipe 7 for draining filtered water being connected to the outer side of the base 2, and a second drain pipe 8 being provided above the spliced ​​pressing component 4.

[0026] The first drain pipe 7 and the second drain pipe 8 are flexible hoses, and the second drain pipe 8 extends to the outside of the consolidation apparatus body 1. Thus, the water inside the consolidation cylinder 3 can be quickly discharged through the double drainage method, which improves the overall drainage efficiency.

[0027] The consolidation apparatus body 1 includes a base plate 101, support rods 102, a pressure box 103, and a pressure rod 104. At least two support rods 102 are vertically fixed on the upper surface of the base plate 101. The pressure box 103 is fixedly connected to the top of the support rods 102. The pressure rod 104 can be vertically moved through the top of the pressure box 103, and the lower end of the pressure rod 104 is fixedly connected to the top of the spliced ​​pressing assembly 4.

[0028] The pressure chamber 103 is equipped with a pressure system, which allows the pressure rod 104 to move up and down, thereby enabling the consolidation of the experimental soil.

[0029] The pressurization system has two modes: constant pressure and constant speed.

[0030] The constant pressure mode allows for adjustment of different loading speeds under a fixed pressure.

[0031] The constant speed mode allows for adjustment of pressure data at a fixed loading speed.

[0032] The upper surface of the base 2 and the lower surface of the spliced ​​pressing assembly 4 are respectively provided with filter sheets 9. The longitudinal section of the base 2 has a stepped structure, and the diameter of its upper step matches the inner diameter of the bottom of the consolidation cylinder 3.

[0033] The filter 9 located on the outside of the base 2 can filter water in the experimental soil to the inside of the base 2, and then discharge it through the first drain pipe 7. The filter 9 located on the outside of the spliced ​​pressing assembly 4 can filter water in the experimental soil to the top of the spliced ​​pressing assembly 4, and then suck it out through the second drain pipe 8.

[0034] The double drainage method can quickly drain water from the experimental soil, thereby improving the overall consolidation effect.

[0035] The splicing pressing assembly 4 includes at least two detachably connected splicing rods 41 and pressing plates 42. The splicing rod 41 includes a main rod body 411. The lower end of the main rod body 411 is provided with an external threaded rod 412 and the inner side is provided with an internal threaded groove 413 that mates with the external threaded rod 412. The bottom end of the lowermost splicing rod 41 is fixedly connected to the pressing plate 42, and the top end of the uppermost splicing rod 41 is fixedly connected to the lower end of the pressure rod 104. The diameter of the pressing plate 42 matches the inner diameter of the consolidation cylinder 3.

[0036] Since the splicing rod 41 can be reduced and increased, the overall length of the splicing pressing component 4 can be changed, allowing the pressing plate 42 to press the experimental soil at different heights, thus improving the flexibility of the overall consolidation of the device.

[0037] The support component 6 includes a horizontally arranged support base plate 61, a first pressure plate 62 and a second pressure plate 63 symmetrically arranged on both sides of the support base plate 61. The support base plate 61 slides against the outside of the limiting frame 5 through the first pressure plate 62 and the second pressure plate 63. A discharge hole 64 is opened at the top of the support base plate 61.

[0038] The first bearing plate 62 is positioned inside the limiting frame 5, and the second bearing plate 63 is positioned at the top of the limiting frame 5, thereby increasing the bearing capacity of the supporting base plate 61 and allowing it to collapse when placed above the consolidation cylinder 3, which then facilitates the sampling of experimental soil.

[0039] The bottom of the consolidation apparatus body 1 is provided with four support legs 10 arranged in a rectangular array, and two bearing columns 11 are symmetrically distributed on the outside of the consolidation cylinder 3.

[0040] Working principle:

[0041] When it is necessary to perform a consolidation operation on the experimental soil, the experimental soil is first saturated, and then the saturated experimental soil is added into the inner side of the consolidation cylinder 3. Then the device is started, and the experimental soil is consolidated and pressurized by pressing the pressing plate 42. The water generated during the pressurization process is discharged from the consolidation cylinder 3 through the first drainage pipe 7 and the second drainage pipe 8.

[0042] After the experimental soil has solidified, the pressing plate 42 is moved upward, and then the solidification cylinder 3 is lifted. During the solidification process, the experimental soil will be adsorbed on the surface of the solidification cylinder 3, so the experimental soil will also be lifted. When the solidification cylinder 3 is lifted above the limiting frame 5, the support component 6 is installed on the outside of the limiting frame 5. The solidification cylinder 3 is released, so that the solidification cylinder 3 can be placed on the top of the support base plate 61. Then, by moving the pressing plate 42 downward, the experimental soil adsorbed on the inside of the solidification cylinder 3 can be discharged through the discharge hole 64, which facilitates the soil collection operation.
