Description

Technical Field

[0001] This invention relates to the field of civil engineering technology, specifically to a foundation pit slope protection and reinforcement device for civil engineering. Background Technology

[0002] In civil engineering construction, foundation pits need to be protected. Foundation pit support is a set of measures to support, reinforce and protect the side walls and surrounding environment of the foundation pit in order to ensure the safety of underground structure construction and the surrounding environment.

[0003] Patent CN113266018B discloses a foundation pit slope protection reinforcement device for civil engineering, including a base plate. A support column is fixedly installed at the top center of the base plate. A motor is fixedly installed inside the support column. A parts mounting cavity is opened on one side of the support column. A first threaded column is movably installed in the parts mounting cavity. The invention drives the first threaded column to rotate by the rotation of the motor inside the support column. When the first threaded column rotates, it drives the first threaded block to move. When the first threaded block moves, it drives the first connecting column to change the angle between itself and the support column. In this way, when the first connecting column moves, it drives the rotating block to move through the pin block and the sliding block. When the rotating block rotates, it rotates around the first fixed column until the rotating block can connect with the limiting ring block. This achieves the slope protection reinforcement effect of the first fixed plate and the second fixed plate.

[0004] The aforementioned patent describes a device that, when the first connecting column moves, drives the rotating block to move via the pin and sliding block. The rotating block rotates around the first fixed column until it connects with the limiting ring block, thereby reinforcing the slope with the first and second fixed plates. However, the device does not provide timely and effective support to the collapse point at the beginning of the collapse. As a result, it is difficult to block the potential energy of the collapse on both sides of the collapse point, and the potential energy during the collapse is not utilized, resulting in a waste of potential energy.

[0009] Preferably, the movable plate has a through groove in the middle, and the size of the through groove is larger than that of the push plate.

[0010] Preferably, each of the unidirectional mechanisms includes a push plate, a double-sided rack, a mounting sleeve, two torsion springs, two rotating shafts, two locking blocks, and two limiting posts. The push plate is disposed at one end of the connecting rod near the slope protection plate. The mounting sleeve is slidably disposed on the fixed plate. The double-sided rack is slidably disposed inside the mounting sleeve. The two limiting posts are fixedly disposed on both sides of the double-sided rack.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] (1) By setting up a reverse thrust mechanism, a fixed plate and a movable plate, this invention can effectively support the collapse point in time from the initial small-scale collapse, taking into account the characteristics of the foundation pit collapse. Timely support of the collapse point can effectively prevent the entire foundation pit from collapsing, avoiding a large number of casualties and property losses. Furthermore, by setting up the first long rod, the second long rod and all connecting rods, all one-way mechanisms are linked to extend and provide preventive support for the entire pit wall, maintaining the shape of the foundation pit. At the same time, the supporting force of a single reverse thrust mechanism or one-way mechanism is dispersed, ensuring the normal use of the device and increasing the overall bearing capacity of the pit wall.

[0016] (2) The present invention utilizes the potential energy of the foundation pit during collapse by setting up three racks, two first gears, two insert plates, two first racks, second gears, second racks, push plates and two fixed frames to provide support force to the collapse point without the need for an additional power source, thus reducing energy consumption. It is worth promoting in batches. Furthermore, by setting up the first wedge block, two insert plates, two second wedge blocks and limiting grooves, the insert plates and the limiting grooves in the two adjacent fixed plates are connected to form a whole, which distributes the excess collapse potential energy of the collapse point and makes the support of the collapse point more stable.

[0017] (3) By setting up a push plate, double-sided rack, torsion spring, locking block and limiting post, the present invention can ensure that the double-sided rack can only slide in one direction, avoid the phenomenon that the double-sided rack will retract after it extends out and hits the side wall of the foundation pit, increase its support stability, and by setting up a second long rod, all double-sided racks can move synchronously in linkage, which can provide pre-support for the uncollapsed points of the entire foundation pit, and prevent the occurrence of continuous collapse.

[0018] (4) In summary, the present invention can provide timely and effective support for the collapse point from the initial small-scale collapse. Timely support for the collapse point can effectively prevent the entire foundation pit from collapsing, avoiding a large number of casualties and property losses. Furthermore, it can utilize the potential energy during the collapse of the foundation pit, providing support to the collapse point without the need for an additional power source, reducing energy consumption. It is worth promoting in batches. Moreover, it can distribute the excess collapse potential energy at the collapse point, providing pre-support for the entire pit wall and preventing continuous collapse. Attached Figure Description

[0027] 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 scope of protection of the present invention.

[0028] Please see Figure 1-7 This invention provides an embodiment of a foundation pit slope protection and reinforcement device for civil engineering, comprising at least one slope protection plate 1, at least one fixed plate 2, at least one movable plate 3, two reverse thrust mechanisms 4, at least one one-way mechanism 5, an X-shaped linkage frame 6, at least one connecting rod 7, a first long rod 8, four connecting grooves 10, a second long rod 11, and at least one slider 13. At least one slope protection plate 1 is sequentially fixedly connected, at least one fixed plate 2 is correspondingly disposed on the back of at least one slope protection plate 1, at least one movable plate 3 is correspondingly disposed between the slope protection plate 1 and the fixed plate 2, and two linkage mechanisms are respectively disposed on the fixed plates 2 at two ends. The linkage mechanisms are fixedly connected to the corresponding movable plates 3. The X-shaped linkage frame 6 is rotatably mounted on the back of each fixed plate 2. The first long rod 8 is fixedly mounted at the ends of the two linkage mechanisms, and the bottom of the first long rod 8 is slidably engaged with one side of the X-shaped linkage frame 6. At least one end of the connecting rod 7 is fixedly mounted on the side wall of the first long rod 8. At least one one-way mechanism 5 is fixedly mounted on the other end of the corresponding connecting rod 7. The second long rod 11 is fixedly mounted at the end of each one-way mechanism 5. The four docking slots 10 are respectively mounted on both sides of the fixed plate 2 at the end. At least one slider 13 is respectively mounted at the rotatable connection point at the end of the X-shaped linkage frame 6. When the side wall of the foundation pit collapses, the slope protection plates 1 break and tilt, hitting the push mechanism 4 and the first long rod 8. The push mechanism 4 drives the movable plate 3 to move towards the foundation pit, hitting the collapsed area. At the same time, the first long rod 8 drives all the one-way mechanisms 5 to extend, hitting the entire surface of the foundation pit, preventing large-scale collapse and personnel injury.

[0029] Specifically, the bottom of the first long rod 8 is provided with a groove 12 for the slider 13 to slide.

[0030] Specifically, each of the reverse thrust mechanisms 4 includes a three-sided rack 41, two first gears 42, two insert plates 43, two first wedge blocks 44, two second wedge blocks 45, two first racks 46, second gears 47, second racks 48, a push plate 49, and two fixed frames 410. The three-sided rack 41 is slidably mounted on the fixed plate 2, and the two fixed frames 410 are mounted on the front side of the fixed plate 2. The two first gears 42 are rotatably mounted on the two fixed frames 410, and the two first gears 42 are respectively located on the three-sided rack 41. On both sides, two first wedge blocks 44 are fixedly mounted on the back of the movable plate 3, two insert plates 43 are slidably inserted into the corresponding insertion slots, two second wedge blocks 45 are fixedly mounted on the corresponding insert plates 43, two first racks 46 are fixedly mounted on the top of the corresponding second wedge blocks 45, the second gear 47 is rotatably mounted below the three-sided rack 41, the second rack 48 is mounted below the second gear 47, and the second rack 48 is slidably engaged with the fixed plate 2, and the push plate 49 is mounted at the end of the second rack 48 near the slope protection plate 1. The slope protection plate 1 abuts against the push plate 49, which drives the second rack 48 to move away from the slope protection plate 1. The movement of the second rack 48 drives the second gear 47 to rotate. The rotation of the second gear 47 drives the three-sided rack 41 and the movable plate 3 to move towards the slope protection plate 1 to abut against the slope protection plate 1 at the collapsed site. The movement of the three-sided rack 41 drives the first gear 42 to rotate. The rotation of the first gear 42 drives the two first racks 46 to slide inward. The sliding of the two first racks 46 drives the two second wedge blocks 45 to slide synchronously. The two second wedge blocks 45 slide against the two first wedge blocks 44. Furthermore, due to the setting of the docking groove 10 and the insert plate 43, the fixed plates 2 on both sides are connected and fixed, dispersing the collapse potential energy in one place and increasing its stability.

[0031] Specifically, the movable plate 3 has a through groove in the middle, and the size of the through groove is larger than that of the push plate 49.

[0032] Specifically, each of the unidirectional mechanisms 5 includes a push plate 51, a double-sided rack 53, a mounting sleeve 54, two torsion springs 55, two rotating shafts 56, two locking blocks 57, and two limiting posts 52. The push plate 51 is disposed at one end of the connecting rod 7 near the slope protection plate 1. The mounting sleeve 54 is slidably disposed on the fixed plate 2. The double-sided rack 53 is slidably disposed inside the mounting sleeve 54. The two limiting posts 52 are fixedly disposed on both sides of the double-sided rack 53. The two rotating shafts 56 are respectively rotatably disposed on both sides of the double-sided rack 53. The two locking blocks 57 are respectively fixedly disposed on the two rotating shafts 56. The two torsion springs 55 are sleeved on the two rotating shafts 56. The slope protection plate 1 tilts and contacts the corresponding push plate 49. The push plate 49 is contacted and drives the connecting rod 7 to move synchronously. The connecting rod 7 drives the first long rod 8 to move. The movement of the first long rod 8 drives each connecting rod 7 and the two second racks 48 to move synchronously. The movement of the second racks 48 drives the second gear 47 to rotate. The rotation of the second gear 47 drives the three-sided rack 41 and the movable plate 3 to move synchronously towards the slope protection plate 1. The movable plate 3 drives the second long rod 11 to move. The movement of the second long rod 11 drives each double-sided rack 53 to move. Due to the setting of the limiting column 52, the double-sided rack 53 cannot slide in the opposite direction, thus providing support for the collapse site. In addition, the one-way mechanism 5 and the reverse pushing mechanism 4 of the whole surface provide support for the collapse site.

[0033] Specifically, each of the card blocks 57 has an arc-shaped surface on its inner end.

[0034] Specifically, each of the fixed plates 2 has a mounting groove on its back for sliding at the rotating parts on both sides of the X-shaped linkage 6.

[0035] Specifically, each of the first wedge blocks 44 has a first inclined surface at its end, and each of the second wedge blocks 45 has a second inclined surface at its end, with the first inclined surface and the second inclined surface cooperating with each other.

[0036] Working principle: When the sidewall of the foundation pit collapses, the slope protection slabs 1 break and tilt, contacting the slope protection slabs 1. The slope protection slabs 1 then contact the push plate 49, which in turn moves the second rack 48 away from the slope protection slabs 1. The movement of the second rack 48 causes the second gear 47 to rotate, which in turn causes the three-sided rack 41 and the movable plate 3 to move towards the slope protection slabs 1 at the collapsed location. The movement of the three-sided rack 41 then causes the first gear 42 to rotate. The rotation causes the two first racks 46 to slide inward, and the sliding of the two first racks 46 causes the two second wedges 45 to slide synchronously. The two second wedges 45 slide and abut against the two first wedges 44. Due to the setting of the docking groove 10 and the insert plate 43, the fixing plates 2 on both sides are connected and fixed, dispersing the collapse potential energy in one place and increasing its stability. By tilting the slope protection plate 1 and abutting against the corresponding push plate 49, the push plate 49 is abutted and drives the connecting rod 7 to move synchronously. The connecting rod 7 drives the first long rod 8 to move. The movement of the long rod 8 drives each connecting rod 7 and the two second racks 48 to move synchronously. The movement of the second racks 48 drives the second gear 47 to rotate. The rotation of the second gear 47 drives the three-sided rack 41 and the movable plate 3 to move synchronously toward the slope protection plate 1. The movable plate 3 drives the second long rod 11 to move. The movement of the second long rod 11 drives each double-sided rack 53 to move. Due to the setting of the limiting column 52, the double-sided rack 53 cannot slide in the opposite direction, thus providing support for the collapsed area and resisting the entire surface of the foundation pit, preventing large-area collapse and personnel injury. It can also be used for protection and reinforcement according to the characteristics of the foundation pit collapse. When the foundation pit initially collapses at one point, the reverse thrust mechanism 4 and the one-way mechanism 5 are triggered in time. The potential energy of the collapse is used to link the reverse thrust mechanism 4 and the one-way mechanism 5 to support the collapse point in time. No matter which point collapses, the collapse point can be supported in time to avoid the collapse area being too large and the collapse potential energy being too large, which the reinforcement device cannot effectively block, thus causing incalculable losses and a large number of casualties.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
