Description

Technical Field

[0001] This utility model belongs to the field of foundation surface repair technology, specifically relating to a curing agent uniform coating device for the surface of soft soil foundation with high water content. Background Technology

[0002] High water-rich soft soil is a special geological condition, characterized primarily by its high water content and soft soil properties. It generally refers to soils with extremely high water content and loose texture, a special form of soft soil. In engineering practice, fine-grained soils with a natural void ratio greater than or equal to 1.0 and a natural water content higher than the liquid limit are generally called soft soils, while high water-rich soft soil further emphasizes its high water content. The characteristics of high water-rich soft soil are mainly reflected in its high water content, large void ratio, high compressibility, low shear strength, and poor permeability. Its water content is usually much higher than that of ordinary soils, giving it high fluidity and plasticity. The large void ratio is due to the large gaps between soil particles caused by the high water content. High compressibility means that high water-rich soft soil is prone to compression deformation under external forces. Low shear strength is due to the weak cohesion between soil particles, resulting in generally lower shear strength in high water-rich soft soil. High-water-rich soft soil has poor permeability, making it difficult for water to flow through the gaps between soil particles. The foundation stability of high-water-rich soft soil is poor, prone to settlement and deformation, threatening the stability of buildings. The nature of soft soil means construction teams cannot directly work on it, increasing construction difficulty and affecting quality. Therefore, it is necessary to first solidify the soft soil to form a stable, load-bearing base layer. In-situ solidification and repair systems for soft soil play a role in solidifying soft soil by using a solidifying agent to bind with the soil, thereby enhancing soil strength. When the surface solidifying agent penetrates the surface of the high-water-rich soft soil foundation and reacts with cementitious materials, it can increase the foundation density and strengthen its hardness. However, when it comes to strengthening the foundation surface during the solidification process, there is a lack of effective and standardized treatment methods for external paving, and a lack of tools suitable for applying the solidifying agent to the foundation surface to achieve uniform and standardized paving. Utility Model Content

[0003] The purpose of this invention is to provide a curing agent uniform coating device for the surface of soft soil foundation with high water content, in order to solve the above-mentioned problems.

[0004] A curing agent uniform coating device for the surface of soft soil foundation with high water content includes a bottom container and two clamping push plates. The bottom container is horizontally arranged, the top of the bottom container is a first inlet opening, the inner cavity of the bottom container is a curing agent receiving cavity, and a discharge gap is machined on one side of the bottom of the bottom container, which is connected to the curing agent receiving cavity. The two clamping push plates are respectively vertically arranged on both sides of the first inlet opening, and the bottom of each clamping push plate is fixedly connected to the top side of the bottom container.

[0005] Each clamping push plate includes a support plate and a push-pull plate. The support plate is an inverted L-shaped plate. The vertical end of the support plate is fixedly connected to the top side of the bottom container. The horizontal end of the support plate is inclinedly provided with a push-pull plate. The high side of the push-pull plate is fixedly connected to the support plate, and the low side of the push-pull plate is the suspended side. The push-pull plate has an elongated hole along its thickness direction. An installation gap is formed between the two clamping push plates.

[0006] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0007] This invention achieves a standardized curing agent spreading process without damaging the foundation surface by using a bottom-mounted container and two clamping push plates in cooperation. Workers simply pour the curing agent slurry into the curing agent container and move the equipment by holding the push plates on the clamping push plates. The curing agent slurry flows evenly onto the foundation surface through the discharge gaps. As the bottom-mounted container is pushed forward, it completes the uniform spreading process on the predetermined area of ​​the foundation surface, ensuring a uniform thickness of the curing agent after spreading. This standardized spreading operation contributes to a uniform flatness and smoothness of the curing agent slurry on the foundation surface, reducing waste of curing agent due to improper operation.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model is described below with reference to specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. The structures, proportions, sizes, etc., illustrated in the accompanying drawings are only for illustrative purposes to aid those skilled in the art and are not intended to limit the implementation conditions of this utility model. Therefore, they do not have substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to the size, without affecting the effects and objectives achieved by this utility model, should still fall within the scope of the technical content disclosed in this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0021] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the solution according to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0022] Specific implementation method one: Combining Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 This embodiment describes a bottom container 1 and two clamping push plates 2. The bottom container 1 is horizontally positioned and is a rectangular box with an open top. The top of the bottom container 1 is the first inlet opening 1-1. The inner cavity of the bottom container 1 is a curing agent receiving cavity 1-2. A discharge gap 3 is machined on one side of the bottom of the bottom container 1, and the discharge gap 3 is connected to the curing agent receiving cavity 1-2. The two clamping push plates 2 are vertically arranged side by side on both sides of the first inlet opening 1-1, and the bottom of each clamping push plate 2 is fixedly connected to the top side of the bottom container 1.

[0023] Each clamping push plate 2 includes a support plate 2-1 and a push-pull piece 2-2. The support plate 2-1 is an inverted L-shaped plate. The vertical end of the support plate 2-1 is fixedly connected to the top side of the bottom container 1. The horizontal end of the support plate 2-1 is inclinedly provided with the push-pull piece 2-2. The high side of the push-pull piece 2-2 is fixedly connected to the support plate 2-1, and the low side of the push-pull piece 2-2 is the suspended side. The push-pull piece 2-2 has an elongated hole 4 along its thickness direction. An installation gap 5 is formed between the two clamping push plates 2.

[0024] Furthermore, when using this curing agent uniform coating device, the staff pours the curing agent slurry into the curing agent receiving cavity 1-2 through the first inlet opening 1-1. The curing agent receiving cavity 1-2 is connected to the discharge gap 3 at the bottom of the bottom container 1. The curing agent slurry is released along the full length of the discharge gap 3, so that the curing agent slurry can flow evenly to the foundation surface at a fixed position, which is beneficial to improving the quality of uniform paving.

[0025] When the worker uses the push-pull plate 2-2 on the clamping push plate 2 to push or pull the curing agent uniform coating device, the curing agent slurry can be evenly released when it comes into contact with the surface of the water-rich soft soil foundation, which is conducive to achieving a uniform paving effect. The push-pull plate 2-2 has elongated holes 4 processed along its thickness direction. The worker can push or pull the device by holding the elongated holes 4, which is convenient for hand gripping. Other tools or driving devices can also be used in conjunction with the elongated holes 4 to lift or push the curing agent uniform coating device, making it convenient and labor-saving for the worker to operate during use.

[0026] Specific Implementation Method Two: This implementation method is a further limitation of Specific Implementation Method One, and also includes at least one feeding box 6. The top of the feeding box 6 is a second inlet opening. The feeding box 6 includes a grid bottom plate 6-1 and a square enclosure frame 6-2. The grid bottom plate 6-1 is fixedly connected to the bottom of the square enclosure frame 6-2. The top surface of the grid bottom plate 6-1 and the inner wall of the square enclosure frame 6-2 enclose a replenishment cavity 6-3. The feeding box 6 is detachably connected to the loading gap 5. The grid bottom plate 6-1 is attached to the bottom container 1. The replenishment cavity 6-3 is connected to the curing agent receiving cavity 1-2. The two outer walls of the feeding box 6 are respectively attached to the inner walls of the two clamping push plates 2. The feeding box 6 is filled with a replenishment curing agent slurry. The replenishment curing agent slurry has the same composition as the curing agent slurry and is only a replenishment slurry for the curing agent slurry. The addition of the volume-enhancing box 6 facilitates the formation of a supplementary volume for the bottom container 1.

[0027] Furthermore, an installation gap 5 is formed between the two clamping push plates 2, allowing the feed box 6 to be placed onto the bottom container 1 through the installation gap 5. The width of the feed box 6 is matched with the width of the installation gap 5 to achieve a stable clamping effect of the two clamping push plates 2 on the feed box 6.

[0028] Furthermore, the inner wall of the clamping push plate 2 can also be machined with protrusions or grooves, and the feeding box 6 can also be machined with grooves or protrusions for detachable connection with the inner wall of the clamping push plate 2, thereby improving the stable connection between the two clamping push plates 2, the feeding box 6 and the bottom container 1 and preventing them from falling off.

[0029] The grid bottom plate 6-1 on the filling box 6 is set on the square enclosing frame 6-2. The top surface of the grid bottom plate 6-1 and the inner wall of the square enclosing frame 6-2 form the filling cavity 6-3. The bottom surface of the grid bottom plate 6-1 is in contact with the first inlet opening 1-1 on the bottom container 1. The worker pours the curing agent slurry into the filling box 6. The curing agent slurry flows into the curing agent receiving cavity 1-2 through the grid bottom plate 6-1, and at the same time flows to the surface of the high water-rich soft soil foundation through the discharge gap 3. This ensures that time and labor are saved during use. The filling box 6 can increase the reserve of curing agent slurry, which is suitable for the operation environment of paving the surface of high water-rich soft soil foundation in a large area.

[0030] Specific Implementation Method 3: This implementation method is a further limitation of Specific Implementation Method 2. When there are multiple feeding boxes 6, the multiple feeding boxes 6 are arranged sequentially from top to bottom within the feeding gap 5.

[0031] Furthermore, the filling box 6 itself is a rectangular frame structure with vertical connections. The bottom of the filling box 6 closest to the bottom container 1 is in contact with and connected to the first inlet opening 1-1 on the bottom container 1. When the worker pours in the curing agent slurry, the curing agent slurry flows into the filling box 6 and into the curing agent receiving cavity 1-2 through the grid bottom plate 6-1. When there are many filling boxes 6, more curing agent slurry can be stored. At the same time, repeated pouring operations are avoided during use, and continuous and large-area paving operations can be carried out at one time, which helps to improve the paving uniformity of one operation.

[0032] Specific implementation method four: This implementation method is a further limitation of specific implementation methods one, two or three. A scraper 7 is provided above the discharge gap 3. One side of the scraper 7 is detachably connected to the outer wall of the bottom container 1, and the other end of the scraper 7 is the suspended scraping side.

[0033] Furthermore, the workers pour the curing agent slurry from the first feed opening 1-1 into the curing agent receiving cavity 1-2. The curing agent slurry flows through the discharge gap 3 to the surface of the water-rich soft soil foundation. A scraper 7 is installed above the discharge gap 3. The workers use the push-pull plate 2-2 on the clamping push plate 2 to push or pull, thereby moving the device on the surface of the water-rich soft soil foundation. At the same time, during the movement, the suspended scraping side of the scraper 7 contacts the surface of the water-rich soft soil foundation to achieve an even coating state, ensuring that the smoothness and flatness of the surface of the water-rich soft soil foundation are improved.

[0034] By raising one clamping pusher plate 2, the other clamping pusher plate 2 with scraper 7 is lowered closer to the surface of the high water-rich soft soil foundation. This facilitates the scraper 7 to smooth the already laid curing agent to the required thickness, thus enabling the local repair and adjustment of the curing agent slurry being laid or already laid.

[0035] Specific Implementation Method Five: This implementation method is a further limitation of Specific Implementation Methods One, Two, Three, or Four. Two sliding rails 8 are arranged side-by-side at the bottom of the bottom container 1, each sliding rail 8 being detachably connected to the bottom surface of the bottom container 1. The sliding rail 8 is a strip-shaped track, easy to disassemble, with a small contact area with the surface of the water-rich soft soil foundation. It contacts the surface of the water-rich soft soil foundation through a sliding pushing mechanism, facilitating movement across the surface of the water-rich soft soil foundation where the curing agent slurry is spread, and reducing the contact and adhesion area between the bottom of the bottom container 1 and the curing agent slurry.

[0036] Furthermore, the bottom of the bottom container 1 is equipped with two slide rails 8. During the operation of the device, the curing agent slurry flows through the discharge gap 3 to the surface of the water-rich soft soil foundation. While the device is moved by the push-pull plate 2-2, the slide rails 8 cooperate with the push-pull plate 2-2, and the scraper 7 flattens the surface. This ensures that when the curing agent slurry is applied to the surface of the water-rich soft soil foundation for a second application, the slide rails 8 prevent sticking and reduce the appearance of marks, thus ensuring the smoothness and flatness of the surface of the water-rich soft soil foundation.

[0037] Specific Implementation Method Six: This implementation method is a further limitation of Specific Implementation Method One, Two, Three, Four or Five. An inclined plate 9 is provided inside the bottom container 1. The inclined plate 9 is inclinedly arranged inside the bottom container 1. The two ends of the inclined plate 9 are respectively attached to the inner walls of the two ends of the bottom container 1. The two sides of the inclined plate 9 are respectively attached to the inner walls of the two sides of the bottom container 1. A strip-shaped notch 10 is processed on the lower side of the inclined plate 9.

[0038] Furthermore, when the curing agent slurry is poured into the bottom container 1, the curing agent slurry flows into the strip-shaped opening 10 through the inclined plate 9. The curing agent slurry flows into the discharge gap 3 from the strip-shaped opening 10, and then flows to the surface of the water-rich soft soil foundation through the discharge gap 3. The scraper 7 is then used to spread it evenly to ensure the smoothness of the surface of the water-rich soft soil foundation, thereby reducing the residual curing agent slurry in the bottom container 1. At the same time, the paving is standardized and uniform without damaging the surface of the water-rich soft soil foundation.

[0039] Specific Implementation Method Seven: This implementation method is a further limitation of Specific Implementation Method Six. The setting of the inclined plate 9 can ensure that an S-shaped flow pattern is formed inside the bottom container 1. That is, the curing agent slurry flows from the high point of the inclined plate 9 to the low point, and flows through the strip-shaped notch 10 to the bottom of the bottom container 1, and finally flows out from the discharge gap 3, forming an S-shaped flow pattern. This increases the flow path of the curing agent slurry and helps to improve the quality and effect of uniform discharge.

[0040] Specific Implementation Method Eight: This implementation method further defines Specific Implementation Method Seven. A grid plate 11 is detachably connected to the strip-shaped notch 10. Multiple guide grooves 12 are machined on the surface of the inclined plate 9, with the lower ends of the multiple guide grooves 12 all facing the grid plate 11. When the grid plate 11 is configured with a plate body with large mesh openings, it is beneficial to provide a flow control effect through the mesh tension, slowing down the flow velocity. It is suitable for use in fine, low-flow local paving treatment of the surface of soft soil foundation with high water content.

[0041] In practical use, the workers pour the curing agent slurry into the bottom container 1. The curing agent slurry flows through the discharge gap 3 to the surface of the water-rich soft soil foundation. Then, the push-pull plate 2-2 is used to push or pull, so that the suspended scraping side of the scraper 7 contacts the surface of the water-rich soft soil foundation to achieve an even slab application. At the same time, the bottom container 1 is a rectangular box, which ensures that the slab area is large and the discharge position during the paving process is controllable and orderly.

[0042] During the paving process of a large area of ​​soft soil foundation with high water content, the grid plate 11 at the strip-shaped notch 10 can be removed to ensure that the curing agent slurry flows from the strip-shaped notch 10 into the discharge gap 3, and then flows to the surface of the soft soil foundation with high water content for paving.

[0043] When performing secondary repairs or small-area paving for supplementation, the grid plate 11 is installed at the strip opening 10, so that the curing agent slurry flows into the strip opening 10 through the grid plate 11, ensuring that the curing agent slurry can flow evenly into the discharge gap 3, forming a uniform and standardized paving state.

[0044] The basic working process of this utility model is as follows: the worker pours the curing agent slurry into the bottom container 1 through the first feed opening 1-1, and the worker holds the elongated hole 4 on the push-pull plate 2-2 to push or pull to move the equipment. The curing agent slurry flows to the surface of the water-rich soft soil foundation through the discharge gap 3.

[0045] This utility model relates to the process of applying slurry to the surface of a large area of ​​high-water-rich soft soil foundation: First, the curing agent slurry is poured into the bottom container 1. Then, the operator inserts and installs a corresponding number of slurry boxes 6 between the two clamping push plates 2. The corresponding number of slurry boxes 6 are installed on the bottom container 1 from top to bottom. Then, the operator pours the prepared curing agent slurry into the slurry box 6. The curing agent slurry flows into the bottom container 1 through the grid bottom plate 6-1 in the slurry box 6, and then flows to the surface of the high-water-rich soft soil foundation through the discharge gap 3 in the bottom container 1. The operator moves the device by holding the long hole 4 on the push-pull plate 2-2, thereby realizing the relevant operations of paving as needed.
