Description

[0001] This invention relates to the field of slope reinforcement technology, specifically to a slope reinforcement device for deep foundation pit excavation. Background Technology
[0002] Slope reinforcement refers to the active or passive reinforcement and protection of slope soil to prevent unstable damage such as landslides, collapses, slippage, and excessive deformation of artificial or natural slopes (such as foundation pit slopes, mountain slopes, and roadbed slopes). This is achieved through engineering measures such as setting up support structures, applying anchoring forces, improving soil properties, and enhancing overall stability.

They have insufficient adhesion and contact friction with the soil, limited reinforcement range, and lack an elastic buffer and adaptive adjustment linkage structure, which easily leads to stress concentration, slippage, and displacement problems. This results in poor device versatility, poor reinforcement stability, and the need for a large amount of manual on-site adjustment, leading to high construction costs, low efficiency, and difficulty in effectively preventing slope instability and damage such as landslides and collapses.

Detailed Implementation
[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 protection scope of the present invention.
[0020] Example 1 (Referring to Figures 1 to 10): The first embodiment of the present invention provides a slope reinforcement device for deep foundation pit excavation. This device includes a base 101 and fixing holes 102. The fixing holes 102 are symmetrically formed through the inner wall of the base 101. An adjustment mechanism 200 is provided on the top of the base 101, and a reinforcement mechanism 300 is provided on the side of the adjustment mechanism 200 away from the base 101. The adjustment mechanism 200 includes a drive motor 201 fixedly connected to the upper surface of the middle part of the base 101, and... The drive assembly 202 is disposed on the top of the base 101; the reinforcement mechanism 300 includes a reinforcement plate 301 symmetrically fixed inside the drive assembly 202, a reinforcement rod 302 slidably connected between the inner walls of the two reinforcement plates 301, a flipping assembly 303 disposed on the reinforcement plate 301, a hinge plate 304 symmetrically rotatably disposed inside the flipping assembly 303, a reinforcement assembly 305 fixedly disposed on the hinge plate 304, and a mounting plate 306 fixedly disposed on the reinforcement assembly 305.
[0021] Example 2, referring to Figures 1 to 6, is the second embodiment of the present invention. This embodiment differs from the first embodiment in that the drive assembly 202 includes a drive telescopic plate 202a symmetrically fixedly connected to the upper surface of the drive motor 201, a groove 202b penetrating the inner wall of the top end of the drive telescopic plate 202a, a drive wheel 202c rotatably connected to the top end of the drive telescopic plate 202a, a connecting plate 202d fixedly connected to the outer wall of the drive wheel 202c, and a connecting plate 202d fixedly connected to the two connecting plates 202d. The system includes an adjusting rod 202e between one end of the drive telescopic plate 202a, an adjusting rod 202f that is slidably connected to the inner walls of both ends of the adjusting rod 202e, a slot 202g on the outer wall of the end of the adjusting rod 202f away from the adjusting rod 202e, an adjusting plate 202h that is fixedly connected to the inner wall of the end of the adjusting rod 202f away from the adjusting rod 202e, a locking block 202i that is fixedly connected to the inner wall of the adjusting plate 202h, and a connecting plate 202j that is fixedly connected to the outer wall of the bottom end of the locking block 202i.
[0022] Furthermore, an electrical connection is established between the drive motor 201 and the external controller. The power transmission end of the drive motor 201 is connected to the power drive equipment inside the drive telescopic plate 202a and the drive wheel 202c through a conductive line. The horizontal width of the groove 202b is the same as the horizontal width of the connecting plate 202d, and the end of the connecting plate 202d near the drive wheel 202c slides inside the groove 202b.
[0023] It should be noted that the rotation angle range of the drive wheel 202c is 0 degrees to 90 degrees, which can drive the connecting plate 202d to achieve precise angle flipping, ensuring that the reinforcement mechanism 300 can fit the slope inclination angle.
[0024] During use: First, the operator places the device in the desired position, then fixes the ground nail to the ground through the fixing hole 102. Next, the operator pulls the two adjusting discs 202h, causing them to slide inside the adjusting rod 202e away from the connecting plate 202d. This causes the adjusting rod 202f to move the slot 202g synchronously, which in turn moves the locking block 202i synchronously. The locking block 202i then moves the connecting plate 202j synchronously, allowing the connecting plate 202j to unfold the reinforcement mechanism 300 during its movement. This unfolded reinforcement mechanism 300 can adapt to different pit slope lengths. Finally, the operator controls the drive motor 201 to start working via an external controller. By energizing the electric drive device installed inside the drive telescopic plate 202a and drive wheel 202c through conductivity, the drive telescopic plate 202a moves vertically up and down as needed. Then, the drive wheel 202c drives the connecting plate 202d to start rotating, causing the connecting plate 202d to flip downward with the drive wheel 202c as the axis. This causes the connecting plate 202d to drive the adjusting rod 202e to flip downward synchronously, which in turn causes the adjusting rod 202e to drive the adjusting rod 202f to move synchronously. The adjusting rod 202f then drives the locking block 202i to move synchronously through the locking slot 202g. The locking block 202i then drives the reinforcement mechanism 300 to move closer to one side of the pit slope through the connecting plate 202j, thus reinforcing the pit slope with the reinforcement mechanism 300.
[0025] By cooperating with the drive telescopic plate 202a, drive wheel 202c, adjustment rod one 202e and adjustment rod two 202f in the adjustment mechanism 200, the vertical height, tilt angle and horizontal unfolding length of the reinforcement mechanism 300 can be adjusted in multiple dimensions. It can adapt to deep foundation pit slopes of different depths, inclinations and widths, greatly improving the adaptability of the device to different foundation pit working conditions. There is no need to customize reinforcement structures for different slopes, reducing construction adaptation costs.
[0026] Referring to Figures 5 to 10, this is the third embodiment of the present invention. This embodiment differs from the second embodiment in that the flipping assembly 303 includes a rectangular groove 303a formed on the outer wall of the reinforcing plate 301, a hinge plate 303b fixedly connected to the inner wall of the top of the rectangular groove 303a, a slide rod 303c fixedly connected to the lower surface of the hinge plate 303b, a spring 303d sleeved on the outer wall of the slide rod 303c, a slider 303e slidably connected to the outer wall of the slide rod 303c, an abutment plate 303f fixedly connected to the side wall of the slider 303e, an abutment groove 303g penetrating the inner wall of the abutment plate 303f, a locking plate 303h slidably connected to the inner wall of the spring 303d, and a locking plate 303h fixedly connected to the locking plate 303h away from the abutment plate 303d. The hinge plate 303i at one end of 3f; the reinforcing component 305 includes a U-shaped frame 305a fixedly connected between the outer walls of the two hinge plates 304, a groove 305b symmetrically opened on the inner wall of the top end of the U-shaped frame 305a away from the hinge plate 304, a U-shaped frame 305c slidably connected to the inner wall of the groove 305b, a connecting plate 305d symmetrically fixedly connected to the inner walls of the U-shaped frame 305c and the connecting plate 305d, a fixing rod 305e symmetrically arranged between the U-shaped frame 305a and the U-shaped frame 305c, a slider 305f slidably connected to the outer wall of the fixing rod 305e, a spring 305g fixedly connected to the outer wall of the slider 305f, and an abutment tooth plate 305h fixedly connected to the outer wall of the slider 305f.
[0027] Furthermore, the reinforcing plate 301 is fixedly connected to the bottom outer wall of the connecting plate 202j, the size of the slider 303e is adapted to the size of the rectangular groove 303a, the spring 303d is fixedly connected between the slider 303e and the hinge plate 303b, the bottom end of the slide rod 303c is fixedly connected to the bottom end of the rectangular groove 303a, and the clamping plate 303h is inclined upward towards the contact plate 303f with the hinge plate 2 303i as the base point.
[0028] It should be noted that: slider 303e and rectangular groove 303a are in clearance fit, and there is no jamming during sliding. Spring 303d is a compression spring. Initially, it is naturally extended. When slider 303e slides upward, it is compressed. Subsequently, it can be elastically reset to return slider 303e to its initial position. The tilt angle of the locking plate 303h is 30 to 45 degrees. This tilt angle setting ensures that when it slides in the abutment groove 303g, it can effectively convert the flipping force of the hinge plate 303i into the upward sliding force of the abutment plate 303f, avoiding force loss.
[0029] Furthermore, hinge plate 304 is rotatably connected to hinge plate 303b and hinge plate 303i respectively, fixed rod 305e is fixedly connected to connecting plate 305d set on U-shaped frame 305a, fixed rod 305e is slidably connected to connecting plate 305d set on U-shaped frame 305c, and spring 305g is fixedly connected between adjacent slider 2 305f and between slider 2 305f and connecting plate 305d.
[0030] It should be noted that: Spring 2 305g is a tension spring. In its initial state, it is naturally contracted. When U-shaped frame 1 305a and U-shaped frame 2 305c move away from each other, spring 2 305g is stretched. Its elastic tension can make the contact tooth plate 305h fit tightly against the slope soil, thus improving the reinforcement effect.
[0031] Furthermore, the mounting plate 306 is fixedly connected to the outer wall of the U-shaped frame 305c at the end away from the U-shaped frame 305a. Five abutting teeth 305h are provided, and the abutting teeth 305h at the beginning and end are fixedly connected to the U-shaped frame 305a and the mounting plate 306 respectively.
[0032] It should be noted that the five contact tooth plates 305h are arranged linearly and equidistantly. The ends of the tooth plates are designed with spikes to increase the contact friction with the slope soil and prevent slippage and displacement during the reinforcement process. Furthermore, the adjacent contact tooth plates 305h are connected in a movable manner and can bend adaptively with the slope surface.
[0033] During use: As the adjusting rod 202f moves the connecting plate 202j away from the center of the adjusting rod 202e via the slot 202g and the block 202i, the connecting plate 202j causes the two reinforcing plates 301 to move away from each other. This causes the reinforcing plates 301 to move synchronously with the hinge plate 303b via the rectangular slot 303a. The two hinge plates 303b then move away from each other via the hinge plate 304, causing the U-shaped frame 305a and the U-shaped frame 305c to slide away from each other within the sliding groove 305b. During this movement, the connecting plate 304... 305d pulls the spring 305g, which is fixedly connected to it, to extend. Simultaneously, the U-shaped frame 305a, through the connecting plate 305d, which is fixedly connected to it, causes the fixed rod 305e to slide inside the connecting plate 305d, which is fixedly connected to the U-shaped frame 305c. Since the forces are mutual, the process of the connecting plate 305d pulling the spring 305g to extend also causes the spring 305g, which is fixedly connected to the slider 305f, to extend synchronously. This causes the slider 305f to simultaneously unfold the contact tooth plate 305h, allowing the contact tooth plate 305h to unfold to a length suitable for the slope of the foundation pit. This expands the contact range against the foundation pit slope and improves the protection against the slope. The effect of strengthening the foundation pit slope: As the connecting plate 202j moves the strengthening plate 301 closer to the side of the foundation pit slope, the bottom end of the contact tooth plate 305h contacts the foundation pit slope first. This causes the contact tooth plate 305h to synchronously rotate the slider 2 305f fixedly connected to its bottom end. The slider 2 305f then drives the fixed rod 305e to synchronously rotate the U-shaped frame 1 305a and U-shaped frame 2 305c. The U-shaped frame 1 305a and U-shaped frame 2 305c then synchronously rotate the hinge plate 2 303i through the hinge plate 304. This causes the hinge plate 2 303i to move the clamping plate 303h closer to the slider 1 303e inside the contact groove 303g. The contact groove 303g drives the contact plate 303f and the slider 303e to slide upward inside the rectangular groove 303a, so that the slider 303e slides upward synchronously on the outer wall of the slide rod 303c. During the movement, the slider 303e compresses the spring 303d, and at the same time, the U-shaped frame 305a and the second U-shaped frame 305c flip away from the reinforcing plate 301 with the hinge plate 303b as the axis. This causes the top of the contact tooth plate 305h to flip towards the side closer to the pit slope, so that the contact tooth plate 305h can completely contact the pit slope with different inclinations, thereby improving the adaptability of the device.
[0034] Through the linkage between the flipping component 303 and the reinforcement component 305, the elastic compression and reset of the spring 303d, the elastic tensile force of the spring 305g, and the spiked structure design of the contact tooth plate 305h can make the contact tooth plate 305h adaptively conform to the slope soil with different curved surfaces and form a tight contact. This not only expands the contact range of the slope reinforcement, but also increases the contact friction with the soil, effectively improving the reinforcement stability and anti-slip effect of deep foundation pit slopes.
