Description
Technical Field
[0001] This utility model relates to the field of building engineering technology, and in particular to a safety protection device for pile holes based on static pressure drilling and compaction. Background Technology
[0002] In modern foundation reinforcement engineering, static pressure compaction pile technology is widely used to improve the stability and enhance the bearing capacity of building foundations. This technology uses static pressure equipment to form pile holes and then fills the holes with compaction material for compaction. However, during construction, especially in the gap between hole formation and backfilling, the exposed pile hole diameter is relatively large, which can easily lead to safety hazards. For example, tools and equipment on site may fall into the pile hole, causing contamination or even blockage, and in severe cases, may cause construction delays. Furthermore, if construction workers inadvertently approach the pile hole, they may fall accidentally, posing a significant threat to their safety.
[0003] Currently, some construction sites use simple materials such as wooden boards and wire mesh to temporarily cover pile holes. However, this method has many problems: the size of the wooden boards or wire mesh is uncontrollable, and it is often difficult to find suitable ones to match various hole diameters. Even if a matching size can be found, its reusability is very poor, and it is not suitable for construction of pile holes of other diameters, making it difficult to adapt to various construction conditions. Furthermore, operators need to be in close contact with the pile hole to place or remove the covering, which poses a high safety risk near large mechanical static pressure drilling equipment.
[0004] Therefore, a safety protection device that is structurally stable, safe and reliable in operation, and adjustable in size is needed to improve construction efficiency and reduce safety hazards. Utility Model Content
[0005] The present invention aims to provide a safety protection device for pile holes based on static pressure drilling and compaction, which can adjust the size and has a simple locking operation.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0007] A safety protection device for pile holes based on static pressure drilling and compaction includes a protective cover, which includes a first cover body and a second cover body. The first cover body and the second cover body are detachably connected by a width adjustment component. The protective cover is provided with a rotating rod locking mechanism, which is used to limit the width adjustment component.
[0008] Furthermore, the width adjustment assembly includes a rotating adjustment rod, a fixed adjustment rod, and a limiting adjustment rod; one end of the rotating adjustment rod is rotatably disposed in the first cover body, and the other end is slidably sleeved in the second cover body; one end of the fixed adjustment rod is fixedly connected to the second cover body, and the other end is slidably sleeved in the first cover body; both ends of the limiting adjustment rod are slidably sleeved in the first cover body and the second cover body, respectively.
[0009] Furthermore, the rotating rod locking mechanism includes a locking component and a control component. The locking component is rotatably disposed within the first cover body, and the control component is disposed on the rotating adjusting rod.
[0010] Furthermore, the locking assembly is located inside the first cover body. The locking assembly includes a pressing block and a locking block. The locking block is connected to a rotating shaft inside the first cover body, and the pressing block is located on the outer wall of the rotating adjustment rod. The locking block is provided with a pressing platform that cooperates with the pressing block, and the locking block is also provided with a locking groove that cooperates with the fixed adjustment rod.
[0011] Furthermore, the control component is located between the first cover and the second cover. The control component includes an L-shaped control rod and a limiting block. The short rod of the L-shaped control rod is rotatably connected to the middle of the rotating adjustment rod. The limiting block is located in the middle of the limiting adjustment rod. The limiting block is provided with a limiting groove, and an auxiliary oblique opening is provided on the outside of the limiting groove. The long rod of the L-shaped control rod is detachably located in the limiting groove.
[0012] Preferably, the long rod of the L-shaped control lever is provided with multiple adjustment grooves, and the limiting groove is provided with an adjustment block, which corresponds to the multiple adjustment grooves; both the first cover and the second cover are provided with telescopic rods.
[0013] Furthermore, the protective cover is also equipped with hooks.
[0014] This utility model has the following beneficial effects:
[0015] 1. This utility model achieves flexible adjustment of the distance between the first cover and the second cover through the width adjustment component, adapting to different pile hole diameters; at the same time, after the width adjustment is completed, the rotating rod locking component achieves width limiting and self-locking functions through the cooperation of the pressing block and the locking block, improving the structural reliability after adjustment, thereby ensuring both safety and adaptability of the device. In addition, the design of the protective cover prevents large debris and personnel from falling into the pile hole, providing good safety protection.
[0016] 2. By adding telescopic rods to the first and second covers, and combining the multiple adjustment slots of the L-shaped control rod with the adjustment blocks in the limit slots, the size adjustment in another direction can be achieved, further improving the multi-directional adaptability of the protective cover.
[0017] 3. By setting up hooks, operators can use long-handled tools to place or remove protective covers at a safe location away from the borehole, reducing the risk of close contact with the pile hole and greatly improving construction safety.
[0018] 4. This utility model can complete the limit and lock by simply adjusting the L-shaped control rod. Under the premise of satisfying the adjustment function and structural stability, it is highly convenient to use. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0031] Example 1:
[0032] This embodiment provides a safety protection device for pile holes based on static pressure drilling and compaction, such as... Figures 1 to 5 As shown, the device includes a protective cover 1, which comprises a first cover body 11 and a second cover body 12. The first cover body 11 and the second cover body 12 are detachably connected by a width adjustment assembly 2. The protective cover 1 is equipped with a rotating rod locking mechanism 3, which limits the width adjustment assembly 2. The distance between the first cover body 11 and the second cover body 12 can be adjusted by the width adjustment assembly 2 to change the width of the protective cover 1, adapting to the different diameters of static pressure compaction pile holes. Since static pressure compaction pile holes are relatively large, the protective cover 1 can cover the pile hole to prevent large debris or workers from falling into it, thus avoiding accidents. Furthermore, the protective cover 1 of the safety protection device can adjust its width to adapt to the size of the pile hole. The rotating rod locking mechanism 3, while limiting the width adjustment assembly 2, also has a self-locking function, allowing for convenient limiting and self-locking after width adjustment, stabilizing the adjusted width and the overall structure of the safety protection device.
[0033] Furthermore, the width adjustment assembly 2 includes a rotating adjustment rod 21, a fixed adjustment rod 22, and a limiting adjustment rod 23. One end of the rotating adjustment rod 21 is rotatably disposed within the first cover 11, and the other end is slidably fitted within the second cover 12. One end of the fixed adjustment rod 22 is fixedly connected to the second cover 12, and the other end is slidably fitted within the first cover 11. Both ends of the limiting adjustment rod 23 are slidably fitted within the first cover 11 and the second cover 12, respectively. The rotating adjustment rod 21, the fixed adjustment rod 22, and the limiting adjustment rod 23 achieve an overall connection between the first cover 11 and the second cover 12, and allow the operator to manually adjust the width distance between the first cover 11 and the second cover 12.
[0034] Specifically, the rotating rod locking mechanism 3 includes a locking component 31 and a control component 32. The locking component 31 is rotatably disposed inside the first cover 11, and the control component 32 is disposed on the rotating adjusting rod 21.
[0035] Furthermore, the locking assembly 31 is disposed within the first cover 11. The locking assembly 31 includes a pressing block 311 and a locking block 312. The locking block 312 is connected to a rotating shaft 3121 within the first cover 11. The pressing block 311 is disposed on the outer wall of the rotating adjusting rod 21. The locking block 312 is provided with a pressing platform 3122 that cooperates with the pressing block 311, and the locking block 312 is also provided with a locking groove 3123 that cooperates with the fixed adjusting rod 22. When the rotating adjusting rod 21 rotates, the pressing block 311 on the rotating adjusting rod 21 rotates accordingly until the pressing block 311 abuts against the pressing platform 3122, causing the locking block 312 to rotate on the rotating shaft 3121. Consequently, the locking groove 3123 on the locking block 312 rotates upward and comes into contact with the fixed adjusting rod 22. The locking groove 3123 has a friction layer on the contact surface with the fixed adjusting rod 22. By using friction and pressing the pressing block 311, the fixed adjustment rod 22 is limited, thereby restricting its sliding and thus limiting the sliding adjustment between the first cover 11 and the second cover 12, that is, limiting the width adjustment component 2.
[0036] Furthermore, the control component 32 is located between the first cover 11 and the second cover 12. The control component 32 includes an L-shaped control rod 321 and a limiting block 322. The short rod of the L-shaped control rod 321 is rotatably connected to the middle of the rotating adjusting rod 21. The limiting block 322 is located in the middle of the limiting adjusting rod 23. The limiting block 322 has a limiting groove 3221, and an auxiliary oblique opening 3222 is provided on the outside of the limiting groove 3221. The long rod of the L-shaped control rod 321 is detachably disposed in the limiting groove 3221. The L-shaped control rod 321 can control the rotation of the rotating adjusting rod 21, and at the same time, the L-shaped control rod 321 itself can rotate circumferentially along the short rod. The downward rotation of the L-shaped control rod 321 can control the rotating shaft 3121 through the pressing block 311 on the rotating adjusting rod 21, thereby limiting and fixing the adjusting rod 22, and completing the control of the locking component 31. When the L-shaped control lever 321 is pressed down, the short lever can rotate circumferentially, allowing the long lever to use elastic deformation to engage with the limiting groove 3221 through the auxiliary oblique opening 3222, thus completing the self-locking of the control component 32.
[0037] Example 2:
[0038] Based on Example 1, in Example 2, as follows: Figure 6 and Figure 7 As shown, further, the long rod of the L-shaped control lever 321 is provided with multiple adjustment slots 3211, and the limiting slot 3221 is provided with an adjustment block 3223, which corresponds to the multiple adjustment slots 3211; both the first cover 11 and the second cover 12 are provided with telescopic rods 13. The first cover 11 and the second cover 12 are divided into two parts by the telescopic rods 13. Compared with the width adjustment assembly 2, width adjustment in another direction can be achieved. Through the cooperation of the multiple adjustment slots 3211 of the long rod of the L-shaped control lever 321 and the adjustment block 3223 in the limiting slot 3221, the telescopic rods 13 of the first cover 11 and the second cover 12 can be limited. The operation of the overall locking and limiting is very simple, requiring only the operation of the L-shaped control lever 321.
[0039] Furthermore, the protective cover 1 is also equipped with a hook ring 14, which allows workers to easily adjust the position of the safety protection device from a distance using a hook rod, facilitating the covering of the pile hole with the safety protection device or its removal. Of course, the width adjustment of the safety protection device needs to be completed in advance, but since the diameter of the compaction pile hole is known in advance during the design phase, adjusting the width of the safety protection device in advance is quite simple.
[0040] Specific application examples:
[0041] In modern foundation reinforcement engineering, static pressure drilling compaction pile construction is widely used. However, the exposed pile hole during the drilling and backfilling process poses a safety hazard due to the risk of large debris or personnel falling in, and traditional covering methods also present safety risks. This invention provides a safety protection device for static pressure drilling compaction pile holes with adjustable width, suitable for pile holes of different diameters. It allows for rapid covering, fixing, and remote removal of the hole opening protection without close contact with the hole opening, effectively reducing construction risks and improving efficiency. The following is a general method of using this invention:
[0042] 1. Pre-adjustment:
[0043] After the hole is formed, the construction personnel first adjust the width of the protective cover 1 according to the diameter range of the pile hole opening; by using the displacement of the rotating adjustment rod 21, the fixed adjustment rod 22 and the limiting adjustment rod 23, the distance between the first cover 11 and the second cover 12 is made to meet the coverage range required by the pile hole opening.
[0044] Rotating the L-shaped control lever 321, through its cooperation with the limiting groove 3221 and the adjusting block 3223, locks the adjusted size and self-locks the control component 32; at the same time, by utilizing the adjustment groove 3211 on the long rod of the L-shaped control lever 321 to cooperate with the limiting groove 3221, the extension length of the telescopic rod 13 on both the first cover 11 and the second cover 12 is locked.
[0045] 2. Device placement:
[0046] After adjustment, construction workers do not need to approach the hole directly. They can use a pre-prepared long-handled hook or rope to place the adjusted protective cover 1 above the pile hole through the hook ring 14, avoiding getting too close to large machinery and equipment.
[0047] 3. On-site safety assurance:
[0048] The protective cover 1 serves as a temporary cover during this stage, effectively preventing large debris, tools, materials, and unauthorized personnel from accidentally falling into the pile hole.
[0049] 4. Backfill preparation and removal:
[0050] When backfilling and compaction work is required, the operator can use a hook or rope to remove the protective cover 1 from a distance, thus removing the cover from the orifice, without having to be exposed close to the orifice and the machinery.
[0051] Through the above-described generalized application process, the construction team can fully utilize the safety protection device of this utility model for efficient, safe, and repeatable temporary protection of the borehole opening between drilling and backfilling, effectively reducing personnel safety risks.
[0052] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
