Description

Technical Field

[0001] This utility model belongs to the field of construction protection technology, and specifically relates to a vibratory compaction construction protection device. Background Technology

[0002] In foundation engineering construction, vibro-compaction is a commonly used method for foundation reinforcement due to its advantages such as strong adaptability, large treatment depth, and fast construction speed. However, the large amount of high-frequency mechanical vibration waves generated during vibro-compaction can propagate through the foundation soil to the surrounding area. Without effective vibration isolation measures, it can easily cause structural damage or uneven settlement to existing buildings in the vicinity, and in severe cases, may lead to safety problems such as wall cracking and foundation misalignment.

[0003] In existing technologies, steel plates are typically used to create a certain degree of isolation zone between the construction area and the protected building through methods such as inserting steel plates and grouting for wall protection. However, such solutions have the following shortcomings: First, ordinary steel plate vibration isolation structures lack effective internal filling and sealing mechanisms, failing to achieve good vibration isolation and sealing effects, allowing vibration waves to still propagate and spread through the gaps in the plates. Second, gaps often occur between adjacent steel plates due to on-site construction errors, with varying widths at the top and bottom, and no adaptive adjustment mechanism, resulting in incomplete filling and reduced overall vibration isolation effect. Third, existing steel plate hoisting structures are relatively simple, lacking convenient foam filling interfaces and automatic sealing devices, leading to problems such as inconvenient construction grouting, poor sealing performance, and leakage and pollution after grouting, making it difficult to meet the requirements of both construction efficiency and vibration isolation sealing in complex construction environments. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a vibratory impact construction protection device that can achieve good vibration isolation and sealing effect and is easy to install, so as to solve the technical problems such as unstable vibration isolation effect, unreliable gap filling and complicated glue injection operation in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vibratory compaction construction protective device, comprising a hollow steel plate, wherein the hollow steel plate is welded from inner and outer plates, the bottom of the hollow steel plate is provided with a conical surface, and the top of the hollow steel plate is symmetrically welded with ear plates;

[0006] The hollow steel plate has uniformly spaced foam injection holes on its surface, and the hollow steel plate has uniformly welded injection guide ribs inside. The injection guide ribs support the inner and outer plates and guide the foam.

[0007] The hollow steel plate has inner protrusions on both sides, and foamed adhesive is left to fill the gaps between the inner protrusions and the inner walls of the inner and outer plates. All the outer surfaces of both sides of the hollow steel plate have mounting grooves, and soft sealing strips are slidably installed inside the mounting grooves. The soft sealing strips are used to fill and seal the gaps between two adjacent hollow steel plates.

[0008] Furthermore, an isolation plate is installed inside the mounting groove, and sliding rods are evenly slidably installed on the surface of the isolation plate. Multiple sliding rods are stacked one on top of the other, and a fixing plate is provided at the outer end of each sliding rod. The width of the fixing plate is the same as the width of the mounting groove.

[0009] Furthermore, the soft sealing strip is installed on the surface of multiple fixing plates, which are positioned outside the isolation plate.

[0010] Furthermore, a spring is fitted onto the surface of the slide bar, the spring being positioned between the isolation plate and the fixed plate, and the spring applying an outward force to the fixed plate.

[0011] Furthermore, a pressing plate is horizontally arranged at one end of the slide rod away from the fixed plate, a rotating rod is rotatably installed on one side inside the mounting groove, and a swing plate is arranged on one side of the rotating rod. The swing plate is used to press and fix the pressing plate.

[0012] Furthermore, the rotating rod passes through the upper surface of the hollow steel plate, and a fixed cap is provided at the top of the rotating rod. A locking bolt is screwed through one side of the fixed cap, and the end of the locking bolt is screwed onto the hollow steel plate. The rotating rod maintains a fixed angle through the locking bolt.

[0013] Furthermore, a sealing plate is uniformly and rotatably installed on one side of the inner wall of the hollow steel plate. The sealing plate corresponds one-to-one with the foam injection hole. A rotating shaft is provided on one side of the sealing plate. The rotating shaft is positioned above the foam injection hole and penetrates the surface of the hollow steel plate. A groove is formed on the surface of the rotating shaft.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention features multiple mounting grooves on the outer side of a hollow steel plate. Within these grooves are a sliding rod, a fixing plate, a soft sealing strip, a separating plate, a spring, a rotating rod, a pressing plate, and a swinging plate, forming an adaptive sealing assembly. Before installation, rotating the rotating rod causes the soft sealing strip to retract, facilitating the insertion of the hollow steel plate into the ground. After installation, releasing the locking bolts causes the soft sealing strip to automatically extend and adhere tightly to adjacent steel plates, effectively filling the gaps. This structure overcomes the problems of inconsistent gap widths and incomplete filling between steel plates in existing technologies, which lead to vibration wave diffusion, thus improving vibration isolation continuity and overall protection.

[0016] This invention, by welding guide ribs inside a hollow steel plate, guides the even distribution of the foam during the injection process, avoiding dead corners in the filling; at the same time, by setting internal protrusions and filling seams in the cavity, effective space is reserved for the flow of the foam, making the filling layer dense and continuous, improving the equipment's ability to buffer and absorb vibration waves; and solves the problems of uneven filling and poor vibration isolation ability of existing steel plates.

[0017] This invention features a sealing plate structure corresponding to the injection hole. The sealing plate sinks under its own weight to automatically seal the injection hole. During the glue injection operation, it can be temporarily opened with the help of the groove structure of the rotating shaft. After the glue injection is completed, it can automatically reset and close. This design ensures that the foaming glue does not leak after injection and avoids sewage backflow during on-site construction, improving the reliability of the seal and effectively solving the problems of difficult glue injection and poor sealing in the prior art.

[0018] This utility model simplifies on-site construction steps and improves construction efficiency by using ear plates and conical structures in conjunction with hoisting and driving operations. At the same time, the protective structure formed by the combination of multiple hollow steel plates is stable as a whole and has a tight connection. It can build a continuous and complete vibration isolation wall between the construction area and the building, thereby effectively blocking the structural damage caused by vibration impact construction to the surrounding buildings and meeting the vibration isolation and protection needs in complex construction environments.

[0026] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0027] refer to Figures 1-6 As shown, a vibratory compaction construction protective device includes a hollow steel plate 1, which is welded from inner and outer plates to form a closed structure to accommodate foamed filling material. The bottom of the hollow steel plate 1 has a conical surface 11 with a tapered angled structure, facilitating insertion into the soil layer under the action of a vibratory hammer to form a preliminary vibration isolation barrier. Symmetrically welded ear plates 12 are provided on the top of the hollow steel plate 1, each ear plate having a lifting hole for use with a lifting machine hook to complete the lifting operation, achieving rapid positioning and efficient construction. Multiple hollow steel plates 1 are combined to form a protective wall structure, enabling physical isolation of vibration waves between the building and the construction area during vibratory compaction construction.

[0028] The hollow steel plate 1 has uniformly opened foam injection holes 13 on its surface. The foam injection holes 13 are used to inject foam and form an internal filling buffer layer. The hollow steel plate 1 has uniformly welded glue injection guide ribs 14 inside. The glue injection guide ribs 14 are vertically distributed inside the cavity, connecting the inner plate and the outer plate. They are used to guide the foam to be evenly distributed during the glue injection process, prevent glue accumulation or blind spots, and at the same time enhance the structural stability of the inner and outer plates, avoiding resonance deformation of the plate due to construction vibration.

[0029] Both sides of the hollow steel plate 1 are provided with inner protrusions 15, which are evenly distributed in the vertical direction to form a filling boundary during the injection of foam adhesive, thereby enhancing the directional aggregation effect of the filler adhesive. Foam adhesive filling gaps are left between the inner protrusions 15 and the inner walls of the inner and outer plates. The filling gaps are closed spaces, which make the foam adhesive filling more compact, thereby enhancing the isolation effect of the protective equipment against vibration waves. Both outer surfaces of the hollow steel plate 1 are provided with mounting grooves 16. The mounting grooves 16 are long groove-shaped structures that run through the outer side of the plate body and are used to accommodate telescopic sealing components. Soft sealing strips 4 are slidably installed inside the mounting grooves 16. The soft sealing strips 4 are made of flexible polymer material and have good deformation adaptability. They are used to fill and seal the gaps between two adjacent hollow steel plates 1, effectively preventing vibration waves from spreading through the gaps and improving the overall vibration isolation performance.

[0030] refer to Figure 6As shown, an isolation plate 17 is installed inside the mounting groove 16. The isolation plate 17 is a partition structure that is tightly attached to the inner wall of the mounting groove. It is used to limit the sliding path of the sliding component and serve as a basis for separating the components. Sliding rods 3 are evenly slidably installed on the surface of the isolation plate 17. There are multiple sliding rods 3, which are stacked one on top of the other to form a parallel distribution structure. The sliding rods 3 are cylindrical structures that pass through the isolation plate 17 and can slide horizontally within the isolation plate 17. They are used to drive the external sealing assembly to move telescopically. A fixing plate 32 is provided at the outer end of the sliding rod 3. The fixing plate 32 is a rectangular plate with the same width as the mounting groove 16. It is used to install and support the soft sealing strip 4 to ensure that it can stably extend or retract during the sliding process.

[0031] refer to Figure 4 and Figure 5 As shown, the soft sealing strip 4 is installed on the surface of multiple fixing plates 32. The soft sealing strip 4 is fixed to the outer surface of the fixing plate 32 by bonding or slotting, and is distributed at the front end and edge of the fixing plate 32. The fixing plate 32 is placed outside the isolation plate 17 and is used to push the soft sealing strip 4 out to both sides of the hollow steel plate 1 under the action of force, thereby realizing the function of sealing and filling the plate gap and adapting to the changes in gap width.

[0032] refer to Figures 4-6 As shown, a spring 5 is fitted on the surface of the slide bar 3. The spring 5 is a helical compression spring, which is placed between the isolation plate 17 and the fixed plate 32 to provide a continuous outward elastic force to push the fixed plate 32 to move outward. The spring 5 can be compressed and deformed according to the force, thereby adjusting the outward expansion of the fixed plate 32 and the soft sealing strip 4 to meet the automatic adjustment sealing requirements under different gap conditions, and improve the overall construction adaptability and protection effect.

[0033] refer to Figure 4 and Figure 5 As shown, a pressing plate 31 is horizontally arranged at the end of the slide rod 3 away from the fixed plate 32. The pressing plate 31 is a sheet-like structure, parallel to the axial end of the slide rod 3, and perpendicularly connected to the slide rod 3. A rotating rod 6 is rotatably installed on one side of the mounting groove 16. The rotating rod 6 passes through the positions of multiple slide rods 3 and achieves centralized control through rotation. A swing plate 61 is arranged on one side of the rotating rod 6. The swing plate 61 is an arc-shaped curved surface structure. By rotating, it contacts multiple pressing plates 31 and applies lateral pressing force, so that multiple slide rods 3 slide inward at the same time, thereby driving the fixed plate 32 to retract into the isolation plate 17, completing the pre-shrinking state of the soft sealing strip 4, which facilitates the smooth insertion of the hollow steel plate 1 into the foundation before construction.

[0034] refer to Figure 1 and Figure 4As shown, the rotating rod 6 penetrates the upper surface of the hollow steel plate 1, and the through hole is set on the central axis of the top of the plate. A fixed cap 62 is set on the top of the rotating rod 6. The fixed cap 62 is used to fix the axial position of the rotating rod 6 and prevent it from rotating unexpectedly during construction. A locking bolt 63 is screwed through one side of the fixed cap 62. The end of the locking bolt 63 is screwed into the threaded hole on the upper part of the hollow steel plate 1. The rotating rod 6 maintains a fixed angle through the locking bolt 63 to ensure that the soft sealing strip 4 is in a contracted state during the insertion process, and to prevent installation difficulties or structural interference caused by premature unfolding.

[0035] refer to Figure 1 and Figure 2 As shown, a sealing plate 2 is uniformly and rotatably installed on one side of the inner wall of the hollow steel plate 1. The sealing plate 2 is a circular baffle structure and is set one-to-one with each foam injection hole 13. A rotating shaft 21 is set on one side of the sealing plate 2. The rotating shaft 21 is vertically connected to the center of the sealing plate 2. The rotating shaft 21 is placed above the foam injection hole 13 and extends to the outer side of the surface of the hollow steel plate 1. After the rotating shaft 21 passes through the surface of the hollow steel plate 1, a slotted groove is opened on its exposed part. During the glue injection operation, a flathead screwdriver is inserted into the groove to rotate and drive the sealing plate 2 to rotate, thereby opening or closing the foam injection hole 13. After the glue injection is completed, the sealing plate 2 can fall back due to its own weight and return to the closed state, effectively preventing the foam from leaking out or the backflow of external sewage, and further ensuring the integrity and sealing of the internal structure of the hollow steel plate 1.

[0036] The working principle of this utility model is as follows: The hollow steel plate 1 is hollow by welding the inner and outer plates and keeping the inside sealed. Due to the weight of the sealing plate 2, it will be vertically downward to seal the foam injection hole 13. During production, foam is injected into the hollow steel plate 1 through the foam injection hole 13. When injecting the glue, the sealing plate 2 can be rotated by the slotted groove on the surface of the rotating shaft 21 through the slotted screwdriver, so that the sealing plate 2 no longer seals the foam injection hole 13, so that the foam gun can be inserted into the foam injection hole 13. After the glue is injected, when the foam gun is pulled out, the sealing plate 2 will reseal the foam injection hole 13 to prevent the foam from leaking out and to prevent sewage from entering the hollow steel plate 1 through the foam injection hole 13 during use.

[0037] Then, the hollow steel plate 1 is hoisted to the construction site using a crane and ear plate 12, and inserted into the ground using a vibratory hammer to block the vibration waves during vibratory compaction. Due to the presence of multiple springs 5, the fixing plate 32 has an outward force, which in turn causes the soft sealing strip 4 to also have an outward force. However, before insertion, the rotating rod 6 needs to be rotated to simultaneously compress multiple pressing plates 31 via the swing plate 61, thereby pulling the sliding rod 3 inward, causing the soft sealing strip 4 to completely retract into the installation groove 16. The angle of the swing plate 61 is fixed by locking the bolts 63. After the hollow steel plate 1 is installed in place, there will inevitably be a gap between two adjacent hollow steel plates 1, and due to… Construction differences can lead to inconsistent gaps between the two hollow steel plates 1, with the gaps potentially exhibiting inconsistent vertical dimensions. In this case, loosening the locking bolts 63 to fix the rotating rod 6 and rotating the swing plate 61 to the side away from the sliding rod 3 allows the fixed plate 32 to move outward due to the presence of the spring 5. This causes the soft sealing strip 4 to extend beyond the side of the hollow steel plate 1 and abut against the other hollow steel plate 1. The soft sealing strip 4 is made of soft material and is compressed by multiple springs 5, thus allowing it to deform to a certain extent and fill the gap between the two adjacent hollow steel plates 1. This prevents vibration waves from spreading through the gaps and reduces the impact on surrounding buildings during construction.

[0038] During construction, hollow steel plates 1 are inserted in rows between the construction site and the building, so that multiple hollow steel plates 1 are combined to form an isolation wall, and the width of the isolation wall is greater than the width of the protected building.

[0039] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
