Description

Technical Field

[0001] This utility model relates to the field of slope support technology, and in particular to a slope support device for excavating adjacent deep foundation pits in desert areas. Background Technology

[0002] The slope support device for adjacent deep foundation pit excavation in desert and Gobi areas is a support structure device used to prevent the slope of the foundation pit from collapsing, settling or sliding during the construction of adjacent deep foundation pits in desert and Gobi areas (i.e., arid and windy landform areas such as deserts, Gobi, and wastelands). This device combines the special geological conditions of the region (such as loose surface, little groundwater, and severe wind erosion) with the high-risk characteristics of deep foundation pit excavation, and is specially designed to improve construction safety and stability.

[0003] The existing equipment requires direct fixation of the slope during installation. Construction personnel must approach or enter the unstable slope area to operate, which poses a high risk of collapse due to loose soil or disturbance, resulting in significant construction safety hazards.

[0004] Therefore, given that the existing devices require direct fixation of the slope during installation, and construction personnel need to operate close to the unstable slope, resulting in high operational risks and a high risk of collapse due to loose soil or disturbance, there is an urgent need to design a new type of slope support device for deep foundation pit excavation in desert areas. Utility Model Content

[0005] To overcome the problems of existing devices requiring direct fixation of the slope during installation, which necessitates construction personnel operating close to the unstable slope, resulting in high operational risks and a high risk of collapse due to loose soil or disturbance, thus posing significant safety hazards.

[0006] The technical solution of this utility model is as follows: a slope support device for deep foundation pit excavation adjacent to desert areas, including an installation plate; it also includes a sliding groove on the left and right sides of the top of the installation plate, a sliding plate slidably connected inside the sliding groove, a rotating shaft connected to the front end of the sliding plate, a connecting block rotatably connected to the outer end of the rotating shaft, a support frame connected to the end of the connecting block away from the rotating shaft, a traction frame connected to the top of the sliding plate, a roller rotatably connected to the upper front side of the installation plate, the roller being movably connected to the support frame, a positioning groove being provided on the top of the installation plate, the sliding plate sliding on the sliding groove drives the rotating shaft to move, the rotating shaft moving drives the connecting block and the support frame to move, the support frame moving drives the roller to rotate inside the installation plate, when the sliding plate moves to the front of the sliding groove, the support frame rotates through the rotating shaft and thus falls down.

[0007] Preferably, by setting up sliding grooves, sliding plates, rotating shafts, and support frames on both sides of the top of the mounting plate, the support frame can move forward along the sliding grooves under the push of the sliding plates, and naturally hang down by rotating the rotating shaft after moving to the predetermined position. This allows the support device to be initially positioned and fixed in a safe area above the slope before the support structure for the slope is deployed, avoiding construction workers from directly performing installation work on the slope, further reducing the risks during construction, and significantly improving the overall safety and efficiency of construction.

[0008] Preferably, the mounting plate is connected to the left and right ends with fixing blocks, and fixing pins are movably connected inside the fixing blocks.

[0009] Preferably, the support frame has an internal cross plate, and a threaded nail is threadedly connected to the center of the internal part of the cross plate.

[0010] Preferably, auxiliary blocks are connected to the left and right ends of the support frame, and auxiliary pins are movably connected inside the auxiliary blocks.

[0011] Preferably, the support frame has two guide plates connected internally, an auxiliary frame connected to the outer end of the mounting plate, and a cross plate used to fix the support frame.

[0012] Preferably, the threaded nail rotates inside the cross plate to insert the threaded nail into the slope, and the auxiliary block is struck with an external hammer.

[0013] Preferably, the auxiliary block slides inside the auxiliary nail, thereby driving the auxiliary nail into the slope, and the guide plate is used to guide the direction of water flow.

[0014] The beneficial effects of this utility model are: 1. By setting up a sliding groove and sliding plate structure on the top of the mounting plate, combined with a rotating shaft and support frame at the front end, the support frame can move forward along the sliding plate along the sliding groove. After moving to the designated position, it can naturally droop by rotating the shaft. This allows the entire device to be accurately positioned and structurally fixed in a safe area above the slope before effectively supporting the slope. This design significantly reduces the need for construction personnel to work in unstable slope areas, effectively avoids the operational risks caused by loose soil or slippage, not only improves the safety of support operations, but also optimizes the construction process, improves installation efficiency and engineering quality control capabilities.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] Please see Figures 1-5 This utility model provides an embodiment of a slope support device for excavating deep foundation pits adjacent to desert areas, including an installation plate 1; it also includes sliding grooves 21 on the left and right sides of the top of the installation plate 1, a sliding plate 22 slidably connected inside the sliding grooves 21, a rotating shaft 23 connected to the front end of the sliding plate 22, a connecting block 24 rotatably connected to the outer end of the rotating shaft 23, a support frame 25 connected to the end of the connecting block 24 away from the rotating shaft 23, a traction frame 26 connected to the top of the sliding plate 22, a roller 27 rotatably connected to the upper front end of the installation plate 1, the roller 27 being movably connected to the support frame 25, a positioning groove 28 being provided on the top of the installation plate 1, the sliding plate 22 sliding on the sliding grooves 21 driving the rotating shaft 23 to move, the movement of the rotating shaft 23 driving the connecting block 24 and the support frame The support frame 25 moves, driving the roller 27 to rotate within the mounting plate 1. When the sliding plate 22 moves to the front of the slide groove 21, the support frame 25 rotates through the pivot 23 and falls down. By setting the slide groove 21, sliding plate 22, pivot 23 and support frame 25 on both sides of the top of the mounting plate 1, the support frame 25 can move forward along the slide groove 21 under the push of the sliding plate 22, and naturally fall down after moving to the predetermined position by rotating through the pivot 23. This allows the support device to be initially positioned and fixed in a safe area above the slope before the support structure for the slope is deployed, avoiding construction workers from directly installing on the slope, further reducing the risk during construction, and significantly improving the overall safety and efficiency of construction.

[0019] Please see Figures 1-5In this embodiment, the mounting plate 1 is connected to the left and right ends of the fixing block 31, and the fixing block 31 is movably connected to the fixing nail 32. The support frame 25 is connected to the inside of the cross plate 33, and the center of the cross plate 33 is threadedly connected to the threaded nail 34. The support frame 25 is connected to the left and right ends of the auxiliary block 35, and the auxiliary block 35 is movably connected to the inside of the auxiliary nail 36. Through the above structural design, the mounting plate 1 can be firmly fixed to the ground or the preset support platform. The cross plate 33 and the threaded nail 34 can effectively enhance the anchoring force of the support frame 25 on the slope. The auxiliary block 35 and the auxiliary nail 36 can achieve multi-point fixation of the slope under the auxiliary hammering action, which improves the structural stability and anti-slip ability of the device under complex geological conditions.

[0020] Please see Figures 2-5 In this embodiment, the support frame 25 has two guide plates 37 connected inside, and the outer end of the mounting plate 1 is connected to an auxiliary frame 38. A cross plate 33 is used to fix the support frame 25. The threaded nail 34 rotates inside the cross plate 33 to insert the threaded nail 34 into the slope. An external hammer is used to strike the auxiliary block 35, which slides inside the auxiliary nail 36 and knocks the auxiliary nail 36 into the slope. The guide plate 37 is used to guide the direction of water flow. By setting the guide plate 37, the direction of water flow can be reasonably guided during construction or rainwater erosion, avoiding direct water flow erosion of the support area and soil loss. At the same time, the combined effect of the threaded nail 34 and the auxiliary nail 36 can realize multi-point mechanical reinforcement of the slope, improve the overall erosion resistance and structural safety. This combined structure enhances the practicality and adaptability of the support device.

[0021] During installation, the mounting plate 1 is first placed on top of the slope. The fixing nail 32 is inserted into the fixing block 31 and tapped until it penetrates the soil. Then, the threaded nail 34 is rotated to separate from the positioning groove 28. Next, the traction frame 26 is pushed, causing the sliding plate 22 to slide. The sliding plate 22 slides forward along the chute 21, causing the rotating shaft 23 to move synchronously. The rotating shaft 23 further drives the connecting block 24 and the support frame 25 to move towards the slope. When the support frame 25 is pushed to the frontmost position of the chute 21, the rotating shaft 23 rotates, causing the support frame 25 to droop naturally, completing the deployment support of the slope from the upper area. The movement of the support frame 25 causes the roller 27 to rotate correspondingly on the upper front side of the mounting plate 1, enhancing the stability and guidance of the deployment process and preventing deviation. After deployment, the support frame 25, through its internal cross... The plate 33 and threaded nails 34 are fixed in contact with the slope. Operators can rotate the threaded nails 34 to extend them from the center of the cross plate 33 towards the slope and insert them into the slope soil to achieve initial anchoring. The auxiliary blocks 35 set at both ends of the support frame 25 can be used in conjunction with external hammering operations to make the auxiliary blocks 35 slide in the auxiliary nails 36 connected inside, thereby hammering the auxiliary nails 36 into the slope to further reinforce and stabilize the slope. At the same time, in order to deal with the problem of water erosion in the desert area, two guide plates 37 are set inside the support frame 25. The guide plates 37 are used to adjust the direction of water flow during construction or when encountering rain, to prevent water flow from directly eroding the support area, reduce the risk of soil loss, and improve the overall durability and environmental adaptability of the structure. The auxiliary frame 38 connected to the outer end of the mounting plate 1 can provide additional support and guidance functions during transportation, installation or construction.

[0022] Through the above steps, by setting a chute 21 on the top of the mounting plate 1, and combining the sliding plate 22, the front rotating shaft 23, and the support frame 25, the support frame 25 can move smoothly forward along the chute 21. After reaching the predetermined position, it automatically rotates and hangs down through the rotating shaft 23, realizing the pre-positioning and fixing of the support structure in the safe area above the slope. Then, the slope support operation is carried out. This structural design effectively avoids construction personnel from entering the slope area for high-risk operations, reduces safety hazards caused by slope loosening or slippage, simplifies the construction process, improves installation efficiency and the controllability of the overall project quality, and greatly enhances the safety and reliability of the support operation. This solves the problem that existing devices require direct fixing of the slope during installation, and construction personnel need to directly approach the unstable slope to operate, resulting in high operational risks and easy collapse due to soil loosening or disturbance, posing significant safety hazards.
