Description

Technical Field

[0001] This invention relates to the field of collapse accident rescue technology, specifically to a reinforcement structure for collapse accident rescue panels and its application method. Background Technology

[0002] Collapse accidents are frequent in construction, mining, road repair, and natural disaster relief. These accidents are often accompanied by soil burial and structural damage, posing a serious threat to the lives of trapped personnel and posing significant challenges to rescue operations. Collapse rescue platforms, as one of the core rescue equipment, are mainly used to quickly erect protective support structures in collapse areas, isolate dangerous areas, prevent secondary collapses, and create safe working spaces for rescuers. They can also serve as platforms for transporting trapped personnel and rescue supplies. Their structural stability directly determines the safety and efficiency of rescue operations.

[0003] Existing collapse rescue panels are mostly one-piece designs. While one-piece rescue panels have high rigidity, they are large in size and heavy in weight, resulting in poor flexibility in transportation and on-site deployment. They are difficult to adapt to collapse pits of different sizes or irregular rescue scenarios. Furthermore, the connecting parts between existing rescue panels are mostly designed with fixed lengths, which cannot be flexibly adjusted according to different spacing between rescue panels. This results in poor adaptability and makes it difficult to meet the reinforcement needs of collapse pits of different sizes, thus having poor practicality. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a reinforcement structure for a collapse accident rescue panel and its usage method, which can effectively solve the problems in the prior art.

[0005] The technical solution adopted in this invention is: a reinforcement structure for a collapse accident rescue panel, including a foundation pit, a plurality of sets of reinforcement components are arranged inside the foundation pit, a reinforcing plate is provided on the outer surface of the reinforcement components, a connecting component is provided between two sets of reinforcement components, a supporting component is provided on the outer surface of the connecting component, a positioning groove is provided at one end of the reinforcing plate near the reinforcement component, a locking bolt is provided on the top of the reinforcement component, and an installation groove is provided on the side of the reinforcing plate near the connecting component.

[0006] Preferably, the reinforcement component includes a first rescue plate and a second rescue plate. Both the first and second rescue plates have protrusions fixedly installed at the ends near the reinforcing plate. The first rescue plate has an insert fixedly installed at the end near the second rescue plate. The second rescue plate has a slot at the end near the first rescue plate.

[0007] The above technical solution, by splitting the rescue plate into a first rescue plate and a second rescue plate, facilitates the transportation and handling of the equipment, and allows for flexible deployment in narrow foundation pit scenarios.

[0008] Preferably, the cross-section of the protrusion is adapted to the cross-section of the positioning groove, and the protrusion can be inserted into the positioning groove. Locking bolts three are provided on both the upper and lower sides of the reinforcing component. The locking bolts three penetrate the reinforcing plate and extend into the first rescue plate and the second rescue plate.

[0009] By using the above technical solution, and by setting the cross-section of the protrusion to match the cross-section of the positioning groove, it is easy to quickly align and install the reinforcing plate on the surface of the reinforcement component, reduce assembly steps, prevent relative displacement between the two, and enhance the linkage load-bearing capacity of the reinforcement component and the reinforcing plate.

[0010] Preferably, the insert block is adapted to the slot, the insert block and the slot are plugged in, and a locking bolt is provided on the outer side of the first rescue plate and the second rescue plate. The locking bolt passes through the second rescue plate and extends into the inside of the insert block.

[0011] The above technical solution, through the matching of the plug and the slot, and the plug-in installation of the plug and the slot, facilitates the rapid splicing of the first and second rescue plates, reduces the difficulty of on-site assembly, adapts to the emergency needs of rescue scenarios, and forms an integrated structure of the first and second rescue plates after splicing by the locking bolt penetrating through the second rescue plate and extending into the plug, improves the load-bearing capacity of the rescue plates, avoids loosening and separation at the splicing point, and prevents secondary collapse of the foundation pit from causing secondary injuries to the trapped personnel.

[0012] Preferably, the cross section of the reinforcing plate is composed of two "cross" shapes, and each end of the reinforcing plate is provided with a positioning groove.

[0013] The above technical solution, by setting the cross section of the reinforcing plate to be composed of two "cross" shapes, can effectively increase the bending and compression resistance of the reinforcing plate, further improve the stability of the reinforcement component, and by providing positioning grooves at each end of the reinforcing plate, it is easy to quickly connect the reinforcing plate with the reinforcement component during installation, thereby improving assembly efficiency.

[0014] Preferably, the connecting assembly includes a supporting main rod and an extension rod. The outer surface of the supporting main rod is provided with several sets of limiting holes at equal intervals. A fixing block is fixedly installed at one end of the supporting main rod and the extension rod near the reinforcing assembly. A connecting seat is rotatably installed on the side of the fixing block away from the supporting main rod and the extension rod. A positioning block is fixedly installed at the end of the connecting seat away from the fixing block. Two sets of locking bolts are symmetrically arranged on one side of the connecting seat. A cavity is provided on the side of the extension rod near the supporting main rod. A limiting post is slidably connected to the outside of the cavity. A return spring is provided between the limiting post and the extension rod.

[0016] Preferably, the main support rod and the extension rod are slidably connected, the positioning block and the mounting groove are adapted to each other, the positioning block and the mounting groove are plugged in, and the limiting post can be inserted into the limiting hole.

[0017] Through the above technical solution, the sliding connection between the main support rod and the extension rod ensures smooth length adjustment. The locking of the adjusted length is achieved by the engagement of the limiting post and the limiting hole, which prevents the connecting components from deforming during rescue operations. The plug-in adaptation between the positioning block and the mounting groove facilitates quick alignment and installation of the connecting components with the reinforcing plate, reducing installation errors and improving installation efficiency. Furthermore, the connection strength between the connecting components and the reinforcing plate is further improved by the locking bolts penetrating the connecting seat and extending to the reinforcing plate.

[0018] Preferably, the support component includes a first reinforcing block and a second reinforcing block. The first reinforcing block is fixedly equipped with buckles at both ends near the second reinforcing block, and the second reinforcing block is provided with buckle grooves at both ends near the first reinforcing block. The outer sides of the first and second reinforcing blocks are provided with slots, and the outer sides of the first and second reinforcing blocks are provided with connecting blocks.

[0019] Preferably, the buckle and the buckle groove are adapted to each other, the buckle and the buckle groove are connected by a snap-fit, the cross section of the mating block is adapted to the combined cross section of the two sets of buckle grooves, and the mating block and the two sets of buckle grooves are connected by a tenon and mortise joint.

[0020] The above technical solution, by setting up a split design for reinforcing block one and reinforcing block two, facilitates the installation on the outside of the connecting component. The two reinforcing blocks can be quickly spliced ​​by the cooperation of the buckle and the slot. The tenon and mortise connection between the mating block and the slot further strengthens the splicing strength, forming a wrap-around support for the connecting component.

[0021] The present invention also provides a construction method for an integrated construction device for grouting of foundation pit walers, comprising the following steps: S1: Clean the installation area of ​​the collapsed foundation pit, level the base, and remove sharp debris.

[0022] S2: Align the insert at the end of the first rescue plate with the slot of the second rescue plate, and push it in smoothly in the horizontal direction until the end faces of the two plates are tightly fitted. Then, tighten the locking bolt through the second rescue plate and into the insert, until there is no relative wobbling between the two plates, thus completing the splicing and fixing of a single set of reinforcement components.

[0023] S3: Take the reinforcing plate, align the positioning groove of the reinforcing plate with the protrusions at both ends of the single set of reinforcement components, and screw in the locking bolts to ensure that the reinforcing plate and the reinforcement components fit tightly.

[0024] S4: Adjust the length of the main support rod and extension rod according to the width of the pit, and rotate the connecting seats on the fixing blocks at both ends of the connecting assembly to a suitable angle so that the positioning block at the end of the connecting seat is aligned with the mounting groove of the reinforcing plate and inserted to quickly install the adjustment assembly.

[0025] S5: Take the first and second reinforcing blocks of the support component, align the buckles at both ends of the first reinforcing block with the buckle groove of the second reinforcing block, press to make the buckles snap into the buckle groove, realize the snap connection between the two, wrap around the outer surface of the connecting component, and align the mating block with the buckle groove on the outside of the first and second reinforcing blocks and snap it in to quickly fix the first and second reinforcing blocks.

[0026] S6: After the rescue is completed, dismantle the equipment in the order of construction steps S5 to S2.

[0027] Compared with the prior art, the present invention provides a reinforcement structure for a collapse accident rescue slab and its application method, which has the following beneficial effects: 1. The collapse accident rescue panel uses a reinforced structure, which splits the rescue panel into a first rescue panel and a second rescue panel, facilitating transportation and handling, and enabling flexible deployment in narrow foundation pit scenarios. It uses plug-in blocks and slots for easy matching and quick splicing of the first and second rescue panels, reducing on-site assembly difficulty and adapting to the emergency needs of rescue scenarios. A locking bolt runs through the second rescue panel and extends into the plug-in block, forming an integrated structure of the first and second rescue panels after splicing, improving the load-bearing capacity of the rescue panel, preventing loosening and separation at the splice, and preventing secondary collapse of the foundation pit from causing secondary injuries to trapped personnel. 2. The collapse accident rescue panel uses a reinforced structure. The sliding connection between the main support rod and the extension rod ensures smooth length adjustment. The locking of the limit post and the limit hole ensures a stable lock on the adjusted length, preventing the connecting components from deforming during rescue operations. The plug-in fit between the positioning block and the installation slot facilitates quick alignment and installation of the connecting components with the reinforcing plate, reducing installation errors and improving installation efficiency. The locking bolts penetrate the connecting seat and extend to the reinforcing plate, further enhancing the connection strength between the connecting components and the reinforcing plate.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example 1: As Figure 1 - Figure 11 As shown, the present invention provides a reinforcement structure for a collapse accident rescue panel, including a foundation pit 1. Several sets of reinforcement components 2 are arranged inside the foundation pit 1. A reinforcing plate 3 is provided on the outer surface of the reinforcement component 2. A connecting component 4 is arranged between two sets of reinforcement components 2. A supporting component 5 is provided on the outer surface of the connecting component 4. A positioning groove 6 is provided at one end of the reinforcing plate 3 near the reinforcement component 2. A locking bolt 7 is provided on the top of the reinforcement component 2. An installation groove 8 is provided on the side of the reinforcing plate 3 near the connecting component 4.

[0032] Specifically, the reinforcement component 2 includes a first rescue plate 201 and a second rescue plate 202. Both the first rescue plate 201 and the second rescue plate 202 have protrusions 203 fixedly installed at their ends near the reinforcing plate 3. An insert 204 is fixedly installed at the end of the first rescue plate 201 near the end of the second rescue plate 202, and a slot 205 is provided at the end of the second rescue plate 202 near the end of the first rescue plate 201. The advantage is that by splitting the rescue plate into the first rescue plate 201 and the second rescue plate 202, it facilitates transportation and handling, and allows for flexible deployment in narrow pit scenarios.

[0033] Specifically, the cross-section of the protrusion 203 is adapted to the cross-section of the positioning groove 6, allowing the protrusion 203 to snap into the positioning groove 6. Locking bolts 7 are provided on both the upper and lower sides of the reinforcing component 2, penetrating the reinforcing plate 3 and extending into the first rescue plate 201 and the second rescue plate 202. The advantage is that by ensuring the cross-section of the protrusion 203 matches the cross-section of the positioning groove 6, the reinforcing plate 3 can be quickly aligned and installed on the surface of the reinforcing component 2, reducing assembly steps. Simultaneously, it prevents relative displacement between the two, enhancing the linkage load-bearing capacity of the reinforcing component 2 and the reinforcing plate 3.

[0034] Specifically, the insert 204 is compatible with the slot 205, and the insert 204 and slot 205 are installed by plugging in. Locking bolts 206 are provided on the outer sides of the first rescue plate 201 and the second rescue plate 202, penetrating the second rescue plate 202 and extending into the insert 204. The advantage is that the compatibility of the insert 204 with the slot 205, and the plug-in installation, facilitates the rapid assembly of the first rescue plate 201 and the second rescue plate 202, reducing on-site assembly difficulty and meeting the emergency needs of rescue scenarios. Furthermore, the locking bolts 206 penetrating the second rescue plate 202 and extending into the insert 204 form an integrated structure for the assembled first rescue plate 201 and the second rescue plate 202, improving the load-bearing capacity of the rescue plates, preventing loosening or separation at the joint, and preventing secondary collapse of the pit 1 that could cause secondary injuries to trapped personnel.

[0035] Specifically, the cross-section of the reinforcing plate 3 is composed of two "cross" shapes, and each end of the reinforcing plate 3 has a positioning groove 6. The advantage is that by setting the cross-section of the reinforcing plate 3 to be composed of two "cross" shapes, the bending and compressive strength of the reinforcing plate 3 can be effectively increased, further improving the stability of the reinforcement component 2. Furthermore, the positioning groove 6 at each end of the reinforcing plate 3 facilitates quick docking with the reinforcement component 2 during installation, improving assembly efficiency.

[0036] Example 2: Figure 2 - Figure 11 As shown, this is an improvement on the previous embodiment.

[0037] Specifically, the connecting component 4 includes a supporting main rod 401 and an extension rod 402. The outer surface of the supporting main rod 401 has several sets of limiting holes 403 spaced evenly. A fixing block 404 is fixedly installed at the end of both the supporting main rod 401 and the extension rod 402 near the reinforcing component 2. A connecting seat 405 is rotatably installed on the side of the fixing block 404 away from the supporting main rod 401 and the extension rod 402. A positioning block 406 is fixedly installed at the end of the connecting seat 405 away from the fixing block 404. Two sets of locking bolts 407 are symmetrically arranged on one side of the connecting seat 405. A cavity 408 is formed on the side of the extension rod 402 near the supporting main rod 401. A limiting post 409 is slidably connected to the outside of the cavity 408. A return spring 410 is provided between the limiting post 409 and the extension rod 402. The advantage is that the connecting component 4 further enhances the load-bearing capacity between the two reinforcing components 2.

[0038] Specifically, the main support rod 401 and the extension rod 402 are slidably connected, the positioning block 406 is adapted to the cross-section of the mounting groove 8, and the positioning block 406 and the mounting groove 8 are plugged in. The limiting post 409 can be inserted into the limiting hole 403. The advantages are that the sliding connection between the main support rod 401 and the extension rod 402 ensures smooth length adjustment, and the plugging of the limiting post 409 into the limiting hole 403 achieves a stable lock on the adjusted length, preventing the connecting component 4 from deforming during rescue operations. The plugging adaptation of the positioning block 406 into the mounting groove 8 facilitates quick alignment and installation of the connecting component 4 with the reinforcing plate 3, reducing installation errors and improving installation efficiency. Furthermore, the second locking bolt 407 penetrates the connecting seat 405 and extends to the reinforcing plate 3, further improving the connection strength between the connecting component 4 and the reinforcing plate 3.

[0039] Example 3: Figure 3 - Figure 11 As shown, this is an improvement on the previous embodiment.

[0040] Specifically, the support component 5 includes a first reinforcing block 501 and a second reinforcing block 502. Both ends of the first reinforcing block 501 near the second reinforcing block 502 are fixedly installed with buckles 503. Both ends of the second reinforcing block 502 near the first reinforcing block 501 are provided with buckle grooves 504. Both the first reinforcing block 501 and the second reinforcing block 502 are provided with slots 505 on their outer sides. Both the first reinforcing block 501 and the second reinforcing block 502 are provided with connecting blocks 506 on their outer sides.

[0041] Specifically, the buckle 503 is adapted to the groove 504, and the buckle 503 and the groove 504 are connected by a snap-fit. The cross-section of the mating block 506 is adapted to the combined cross-section of the two sets of grooves 505, and the mating block 506 and the two sets of grooves 505 are connected by a mortise and tenon joint. The advantage is that by setting the split design of the first reinforcing block 501 and the second reinforcing block 502, it is easy to install on the outside of the connecting component 4. The quick splicing of the two reinforcing blocks is achieved by the cooperation of the buckle 503 and the groove 504. The mortise and tenon joint between the mating block 506 and the groove 505 further strengthens the splicing strength, forming a wrap-around support for the connecting component 4.

[0042] Working principle: During use, the foundation pit 1 at the collapse accident site is first initially cleared, removing loose soil, rocks, debris, and other obstacles. Then, the insert block 204 and slot 205 are fitted together, and the insert block 204 and slot 205 are plug-in installed, facilitating the rapid assembly of the first rescue plate 201 and the second rescue plate 202. This reduces on-site assembly difficulty and meets the emergency needs of rescue scenarios. A locking bolt 206 penetrates the second rescue plate 202 and extends into the insert block 204, forming a unified structure between the first rescue plate 201 and the second rescue plate 202. This improves the load-bearing capacity of the rescue plates, prevents loosening and separation at the joint, and prevents further collapse of the foundation pit 1. The secondary collapse caused secondary injuries to the trapped personnel. By ensuring that the cross-section of the protrusion 203 matches the cross-section of the positioning groove 6, the reinforcing plate 3 can be quickly aligned and installed on the surface of the reinforcement component 2, reducing assembly steps and preventing relative displacement between the two. This enhances the linkage load-bearing capacity of the reinforcement component 2 and the reinforcing plate 3. By setting the cross-section of the reinforcing plate 3 to consist of two "cross" shapes, the bending and compression resistance of the reinforcing plate 3 can be effectively increased, further improving the stability of the reinforcement component 2. Then, according to the spacing between the two sets of reinforcement components 2, the length of the connecting component 4 is adjusted, and the limiting post 409 on the outside of the extension rod 402 is pressed, compressing the return spring 410 to disengage the limiting post 409. Adjust the overall length of the sliding extension rod 402 by moving it away from the limiting hole 403 of the main support rod 401 until the positioning blocks 406 at both ends of the connecting component 4 are aligned with the mounting groove 8 of the reinforcing plate 3. Release the limiting post 409, and the return spring 410 pushes the limiting post 409 into the corresponding limiting hole 403 to complete the length locking. Insert the positioning blocks 406 at both ends of the connecting component 4 into the mounting groove 8 of the reinforcing plate 3 to achieve plug-in engagement. Rotate the connecting seat 405 to adjust the connection angle so that the main support rod 401, extension rod 402 and reinforcing plate 3 are balanced by force. Then tighten the two sets of locking bolts 407 on one side of the connecting seat 405 to fix the connecting seat 405 and the fixing block 404. The relative positions are adjusted to prevent the connecting component 4 from rotating or shifting. Finally, reinforcing block 1 501 and reinforcing block 2 502 are respectively attached to the outside of the connecting component 4, so that the buckle 503 of reinforcing block 1 501 is aligned with the buckle groove 504 of reinforcing block 2 502. Pressing is used to achieve fastening and fixation, forming support for the connecting component 4. Then, the mating block 506 is aligned with the buckle groove 505 on the outside of reinforcing block 1 501 and reinforcing block 2 502, and embedded into the buckle groove 505 using the tenon and mortise connection method. This can effectively improve the overall connection of reinforcing block 1 501 and reinforcing block 2 502, avoid separation at the splice, and at the same time distribute the local concentrated load of the connecting component 4 to prevent the connecting component 4 from bending and deforming.
