[0023] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0024] like Figures 1-5As shown, the foundation pit support and reinforcement device provided in this embodiment includes two metal support panels 1. The two metal support panels 1 are connected together by several screw-in support telescopic rods 2. Both ends of the screw-in support telescopic rods 2 are fixed to the two metal support panels 1 by fixing buckles 3. A first transverse splicing interface 4 is symmetrically arranged on the inner side of one end of the two metal support panels 1, and a second transverse splicing interface 5 that matches the first transverse splicing interface 4 is symmetrically arranged on the outer side of the other end of the two metal support panels 1. A longitudinal insertion block 6 is provided at the top of the two metal support panels 1, and the bottom of the two metal support panels 1 is set as spikes to facilitate better insertion of the bottom of the two metal support panels 1 into the foundation pit. The two metal support panels 1 facilitate the support and reinforcement of the soil on both sides of the foundation pit. The several screw-in support telescopic rods 2 facilitate the connection of the two metal support panels 1 together, and also facilitate the connection of the two metal support panels 1. The fixed support and the fixed buckle 3 facilitate the fixation of the two ends of the screw-in support telescopic rod 2 between the two metal support plates 1. The first transverse splicing interface 4 and the second transverse splicing interface 5 cooperate with each other to facilitate the transverse splicing and assembly of several of these devices, thereby adapting to foundation pits of different transverse lengths. The longitudinal access block 6 facilitates the longitudinal insertion and installation of the foundation pit support and reinforcement plate. The two metal support plates 1, several screw-in support telescopic rods 2, several fixed buckles 3, the first transverse splicing interface 4, the second transverse splicing interface 5, and the longitudinal access block 6 cooperate with each other, which allows for the overall splicing of several individual units, thereby enabling better support and reinforcement of the foundation pit. This also allows several foundation pit support and reinforcement devices to evenly resist the pressure from the inner wall of the foundation pit. At the same time, soil or sandbags can be filled between the two assembled metal support plates 1 to increase the weight of the device itself, thereby improving the support effect of the device.

[0025] Furthermore, such as Figure 2 and Figure 5 As shown, the first transverse splicing interface 4 includes a first splicing notch 7 symmetrically opened on the inner side of one end of the two metal support panels 1 and a first T-shaped splicing slider 8 disposed in the first splicing notch 7. The second transverse splicing interface 5 includes a second splicing notch 22 symmetrically opened on the outer side of the end of the two metal support panels 1 away from the first transverse splicing interface 4 and a first T-shaped splicing groove 9 disposed in the second splicing notch 22. The first splicing notch 7, the second splicing notch 22, the first T-shaped splicing slider 8 and the first T-shaped splicing groove 9 cooperate with each other to facilitate the transverse splicing and snapping of several metal support panels 1 together, thereby realizing that several of these devices can be connected together transversely, which allows the pressure of the foundation pit on the metal support panels 1 to be evenly distributed.

[0026] Furthermore, such as Figure 2 and Figure 5As shown, the first T-shaped splicing slider 8 and the first T-shaped splicing groove 9 are mutually fitted and adapted. Both metal support plates 1 are provided with sliding mounting grooves 10. Both ends of the screw-on support telescopic rod 2 are slidably fitted into the sliding mounting grooves 10. The sliding mounting grooves 10 facilitate the slidable installation of both ends of the screw-on support telescopic rod 2 between the two metal support plates 1.

[0027] Furthermore, such as Figure 3 As shown, the screw-on support telescopic rod 2 includes a storage support sleeve 11, a support screw 12 symmetrically rotated and screwed into the storage support sleeve 11, a snap-fit ​​mounting block 13 located at the end of the support screw 12, and a rotating groove 14 circumferentially cut into the central surface of the storage support sleeve 11. The storage support sleeve 11 facilitates the screwing and storage of the two support screws 12, and rotating the storage support sleeve 11 facilitates the free extension and retraction of the screw-on support telescopic rod 2. The snap-fit ​​mounting block 13 facilitates the installation of both ends of the screw-on support telescopic rod 2 between the two metal support plates 1. The rotating groove 14 facilitates the rotation of the storage support sleeve 11 by using a wrench, thereby realizing the contraction and extension of the two support screws 12 by the storage support sleeve 11.

[0028] Furthermore, such as Figure 3 and Figure 5 As shown, the upper and lower end faces of the snap-fit ​​mounting block 13 are provided with limiting and fixing sliders 15, and the sliding mounting groove 10 is provided with a limiting and fixing groove 16 that is adapted to the limiting and fixing sliders 15. The limiting and fixing sliders 15 and the limiting and fixing grooves 16 cooperate with each other to facilitate the snap-fit ​​mounting block 13 to be slidably installed in the sliding mounting groove 10.

[0029] Furthermore, such as Figure 4 As shown, the fixing buckle 3 includes a limiting block 17, a second T-shaped splicing slider 18 symmetrically arranged on the upper and lower ends of the limiting block 17, and a fixing bolt 19 rotatably screwed onto the limiting block 17. The limiting block 17 facilitates the installation of the fixing buckle 3 in the sliding mounting groove 10, and the fixing bolt 19 facilitates the fixing of the fixing buckle 3 in the sliding mounting groove 10, thereby achieving the limiting and fixing of the rotating support telescopic rod 2.

[0030] Furthermore, such as Figure 5 As shown, the inner side of the metal support panel 1 is provided with a second T-shaped splicing groove 20 that is compatible with the second T-shaped splicing slider 18. The limiting block 17 is fixedly installed in the sliding mounting groove 10 next to the snap-fit ​​mounting block 13 by fixing bolts 19. The second T-shaped splicing slider 18 and the second T-shaped splicing groove 20 cooperate with each other to facilitate the fixed snap-fit ​​installation of the limiting block 17 in the sliding mounting groove 10 next to the snap-fit ​​mounting block 13.

[0031] Furthermore, such as Figure 1As shown, a rubber sealing plate 21 is fitted into the empty space in the sliding mounting groove 10. The rubber sealing plate 21 can protect the empty space in the sliding mounting groove 10 and prevent workers from damaging the sliding mounting groove 10 during operation.

[0032] like Figures 1-5 As shown, the principle of the foundation pit support and reinforcement device provided in this embodiment is as follows: When using the device, the workers should first dig the required foundation pit at the construction site, then take out several of the devices according to the excavated foundation pit, then splice the several devices together end to end, and attach one side of the several devices spliced ​​together to one side of the foundation pit, and then press and drive the several devices spliced ​​together into the soil layer at the bottom of the foundation pit.

[0033] When assembling the device, first take out two metal support panels 1, then take out four screw-on support telescopic rods 2, and slide the four screw-on support telescopic rods 2 into the end corners of the sliding mounting grooves 10 inside the two metal support panels 1. Then, use the fixing buckles 3 to limit and fix both ends of the screw-on support telescopic rods 2 in the sliding mounting grooves 10 inside the two metal support panels 1. Finally, install the rubber sealing plate 21 in the empty space in the sliding mounting groove 10.

[0034] When assembling several of these devices end to end, it is necessary to ensure that the first splicing notch 7 in the first horizontal splicing interface 4 and the second splicing notch 22 in the second horizontal splicing interface 5 are correspondingly engaged and interlocked together. At the same time, it is also necessary to ensure that the first T-shaped splicing slider 8 and the first T-shaped splicing groove 9 are also mutually engaged and fixed together. When assembling this device, it is necessary to ensure that the second T-shaped splicing slider 18 and the second T-shaped splicing groove 20 are correspondingly engaged and interlocked together. At the same time, it is also necessary to ensure that the limiting and fixing slider 15 and the limiting and fixing groove 16 are correspondingly engaged and interlocked together.

[0035] If the excavated pit is too deep, the pit support reinforcement plate can be installed by longitudinally inserting the longitudinal access block 6. The pit support reinforcement plate installed upward must have holes and slots that are compatible with the longitudinal access block 6. At this time, the two opposite pit support reinforcement plates can also be connected together by several screw-on support telescopic rods 2 and several fixed buckles 3 in a sliding and engaging manner.

[0036] When the width of the foundation pit excavated by the workers is narrow, the screw-on support telescopic rod 2 of a more suitable length can be replaced. This allows the two metal support plates 1 in the device to abut against the inner walls of the foundation pit on both sides after being opened. Then the device is pressed down so that the spiked parts at the bottom of the two metal support plates 1 can be embedded in the soil layer. This can provide more stable support and reinforcement for the foundation pit.

[0037] When the excavated pit is wide, the metal support plate 1 on either side of the device can be placed against the side of the pit, and then the device can be pressed down so that the spiked parts at the bottom of the two metal support plates 1 are embedded in the soil. When the soil at the work site is relatively loose, soil can be filled between the two metal support plates 1 in the device, and the filled soil can be pressed and compacted. When the soil at the work site is relatively loose, sandbags can be filled between the two metal support plates 1 in the device, which can increase the weight of the device itself, thereby providing more stable support and reinforcement for the pit.
