Description

Technical Field

[0001] The invention relates to the technical field of slope support structures, in particular to a trench excavation support device that improves slope stability. Background Art

[0002] Slope refers to the inclined slope with a certain angle set on both sides of the road and water conservancy to ensure the stability of the foundation during road and water conservancy operations. Special support structure equipment will be installed during the construction and excavation process to prevent the slope from loosening or collapsing during construction, thereby improving safety.

[0003] The existing Chinese patent application with publication number CN117266177A discloses a support device and a support method for a slope support project, comprising a slope, a concrete slope protection for support is provided on the slope surface of the slope, a concrete base for support is provided on the slope surface of the slope, a drainage structure for drainage is provided on the concrete slope protection and the concrete base, a protective member for protection is provided on the concrete slope protection and the concrete base, the drainage structure comprises a first drainage groove opened inside the concrete slope protection and a second drainage groove opened inside the concrete base, the first drainage groove is provided on the concrete slope protection and the concrete base, The water trough and the second drainage trough are arranged in a linear array, and the inner cavities of the first drainage trough and the second drainage trough are communicated. The drainage structure also includes a water accumulation pool opened inside the top of the concrete base; this invention uses a spiral turntable, at this time the turntable drives the threaded rod to move in the inner cavity of the square threaded cylinder, and the square threaded cylinder drives the slider to move along the outer surface of the slide rod. During this period, the rotating block rotates inside the second hinged ear with the rotating shaft as the axis, and the protective plate rotates inside the first hinged ear with the rotating rod as the axis until the protective plate is rotated to a suitable angle, thereby realizing the support and protection operation of the corresponding angle slope.

[0004] However, this slope support structure has the following defects when it is used:

[0005] 1. When existing slope support structures are used to support and protect the slopes of water conservancy projects or roads, they are generally erected in advance before excavation. However, the support structures erected in advance using traditional technology are difficult to cooperate with the excavator to carry out pit operations when excavating the underlying soil, affecting the normal progress of construction. At the same time, when the excavator is operating, the operating parts are prone to collision with the slope support structure, resulting in low safety of the operation.

[0006] 2. When existing slope support structures are used to support and protect the inner walls of roads and water conservancy excavations, most of the force is applied directly to the protective netting. When heavier soil directly impacts the protective netting, uneven impact points can cause significant damage to the mounting elements (through screws) of the netting, and in severe cases, even cause disconnection.

[0043] Compared with the existing technology, one or more of the above technical solutions have the following beneficial effects:

[0044] 1. In the trench excavation support equipment that improves the stability of the slope, the structures for supporting and fixing at horizontal, vertical and inclined angles are all jacks, which can effectively improve the stability and firmness of the support for the inner wall of the trench through the structure of the jack. At the same time, the design of the horizontal and vertical jacks can ensure that there are no obstructions in the space in the center of the two, making it convenient for the working arm of the excavator to pass through the part and carry out construction operations. And in the process of the horizontal jack operating to drive the horizontal inner support and the moving parts to move telescopically, the oblique jack installed on the top can automatically rotate and always form a triangle with the embankment column, the horizontal inner support and the moving parts, further improving the effect and ability of the embankment column to support and protect the inner wall of the trench;

[0045] 2. In the trench excavation support equipment that improves slope stability, the bottom of the protective net that supports the inner wall of the trench is supported by multiple groups of horizontal plates, center rods, and a group of vertical plates connected in a cross-connection. This can improve the support capacity of the protective net while dividing the protective part of the protective net into multiple parts. At this time, the sliding rods and guide cylinders (for support) set inside each group of protective parts can further improve the ability and effect of protecting each part of the protective net, and reduce the risk of the connection part of the protective net breaking when different parts of the protective net collapse. In addition, the sliding rods and guide cylinders used for protection can form a triangle with the horizontal plates, center rods, and vertical plates respectively to support the horizontal plates, center rods, and vertical plates, reducing the risk of damage or even breakage of the horizontal plates, center rods, and vertical plates due to the impact force when the soil layer collapses;

[0046] 3. In the trench excavation support equipment that improves slope stability, when the longitudinal jack operates to press the transverse inner support member and the moving member against the inner wall of the trench, the movement of the transverse inner support member and the moving member will drive the top-connected embankment column to move, and also drive the horizontal plate connected to the inner side of the embankment column through the assembly portion to move. At this time, when the horizontal plate is telescopically moved, the guide cylinder and sliding rod installed on its top will perform corresponding rotational and telescopic movements through the rotatably connected mounting base and top seat (the sliding rod slides inside the guide cylinder), and always form a triangle with the horizontal plate, center rod and vertical plate, ensuring that the support equipment of the present invention is applicable to support operations in trenches of different areas;

[0047] 4. In trench excavation support equipment designed to enhance slope stability, multiple metal protrusions on the sides of the transverse internal supports and movable members extend into the soil layer within the trench when installed, further enhancing their grip and retention of the soil within the trench. Furthermore, during the actual protection of the net, the support springs and telescopic springs provide a buffer against vibration and impact forces during support, enhancing the safety and service life of the support equipment during trench soil support.

[0069] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0070] See also Figures 1-12 A trench excavation support device for improving slope stability includes a right-angle support mechanism 10, a cross support assembly 20, a triangular stabilizing assembly 30, and a protective net 40. The right-angle support mechanism 10 is arranged inside the trench and supports the trench slope. A cross support assembly 20 is provided on the side of the cross support assembly 20 that contacts the slope. Multiple sets of triangular stabilizing assemblies 30 are installed inside the cross support assembly 20. The side of the cross support assembly 20 is provided with a triangular stabilizing assembly 30 on the side of the right-angle support mechanism 10. The protective net 40 on the surface is in conflict with the trench slope, wherein the right-angle support mechanism 10 includes a foundation pit support assembly 50, the foundation pit support assembly 50 is arranged inside the trench and in conflict with the inner wall of the trench, and the top of the foundation pit support assembly 50 is detachably installed with a side support assembly 60 by screws, and the side support assembly 60 is provided with two groups, and a cross support assembly 20 is installed between the two groups of side support assemblies 60, and a protective net 40 is provided on the side of the side support assembly 60.

[0071] The working principle is as follows: When protecting the slopes of roads or water conservancy projects, the foundation pit support assembly 50 is first installed on the inner wall of the trench being constructed and automatically adjusted to match the size of the trench to ensure that the four sets of edge portions of the foundation pit support assembly 50 can contact and fit with the four inner walls of the trench, ensuring the stability and firmness of the installation of the foundation pit support assembly 50 and the trench. At the same time, the center of the foundation pit support assembly 50 is set to be hollow, which does not affect the subsequent excavator operating parts extending into the trench for excavation and other operations. In addition, when the foundation pit support assembly 50 is in operation, the side support assembly 60 and cross support assembly 20 installed at its top edge can be adjusted to move and telescope accordingly, and always contact the inner wall of the trench. After the adjustment is completed, the corresponding size of the protective net 40 is installed using screws. The protective net 40 reduces the probability of slope collapse during construction and improves construction safety. Moreover, during the construction process, the cross-arranged cross support assembly 20 and the multiple sets of triangular stabilization assemblies 30 supporting the cross support assembly 20 can reduce the risk of fracture at the connection of the protection net 40 due to soil collapse, and further enhance the ability and effect of the protection net 40 to support the slope soil layer.

[0072] Specific reference Figure 11 and Figure 12 The cross support assembly 20 includes a horizontal plate 201, which is installed on the side of the side support assembly 60, and is internally slidably connected to a center rod 202 extending to the outside, and the other side of the center rod 202 extends to the inside of another set of horizontal plates 201; an inner through hole 203, the inner through hole 203 is opened at the center of the center rod 202, and a movable protrusion 204 is installed inside, and the movable protrusion 204 is installed on the left and right sides of the vertical plate 205, and a support disc 206 installed on the side of the movable protrusion 204 is provided at the center of the side of the vertical plate 205, and the side of the support disc 206 is in contact with the protective net 40, wherein the left and right sides of the vertical plate 205 are in contact with the center rod 202, and a triangular stabilizing assembly 30 is provided at the angle between the connecting part of the horizontal plate 201 and the vertical plate 205.

[0073] In this embodiment, one end of the center rod 202 located inside the horizontal plate 201 protrudes outward and constitutes an extension portion 2021. The extension portion 2021 passes through the guide groove 2022 and is slidably connected to the side of the horizontal plate 201. The guide groove 2022 is opened on the inner wall of the horizontal plate 201 and is arranged close to one side of another group of horizontal plates 201. The design of the guide groove 2022 can guide and limit the moving extension portion 2021, so that the extension portion 2021 can only move in one direction inside the guide groove 2022, thereby improving the stability and firmness of the support for the protective net 40.

[0074] In the trench excavation support device for improving slope stability of the present invention, when the side support assembly 60 is in operation, the horizontal plate 201 mounted on its side moves. At this time, the center rod 202, which is slidably connected within the horizontal plate 201, slides and remains slidably connected to the horizontal plate 201 (via the extension 2021 and the guide groove 2022). Simultaneously, a set of vertical plates 205 and multiple sets of horizontal plates 201 arranged in a cross-connection divide the portion supporting the protective net 40 into multiple groups, facilitating support and protection of various portions of the protective net 40.

[0075] Specific reference Figure 11 and Figure 12 The triangular stabilizing assembly 30 includes a mounting base 301, which is mounted on the top of the horizontal plate 201 by screws and is internally rotatably connected to a sliding rod 302, which extends to the interior of the guide cylinder 303 and is slidably connected to the inner wall of the guide cylinder 303; side protrusions 304, which are mounted on both sides of the bottom of the guide cylinder 303 and are externally rotatably connected to a mounting top seat 305, which is mounted on the side of the vertical plate 205 by screws.

[0076] In this embodiment, a group of guide cylinders 303 are rotatably connected to the left and right sides of the mounting top 305, and a telescopic spring 3031 is arranged inside the guide cylinder 303, wherein one end of the telescopic spring 3031 is connected to the inner wall of the guide cylinder 303 through damping, and the other end of the telescopic spring 3031 is connected to the side of the sliding rod 302, and wherein the guide cylinder 303 and the sliding rod 302 respectively form a triangle with the horizontal plate 201 and the vertical plate 205. Through the design of the telescopic spring 3031, compression or stretching operations can be performed when the sliding rod 302 is telescopically moved, and the connection state with the sliding rod 302 is always maintained, thereby improving the stability of the protective net 40 when supporting it.

[0077] In the trench excavation support equipment for improving slope stability of the present invention, the horizontal plate 201 and the vertical plate 205 for support can be reinforced by the triangular sliding rod 302 and the guide cylinder 303, thereby avoiding the problem of the vertical plate 205 and the horizontal plate 201 being broken due to the impact force of the soil layer. At the same time, the various parts separated by the vertical plate 205 and the horizontal plate 201 are supported and protected, reducing the probability of different parts being sunken due to the impact force of the soil layer, thereby improving the support effect of the protective net 40 on the soil layer. In addition, during the movement of the horizontal plate 201, the sliding rod 302 and the guide cylinder 303 connected in rotation can be rotated and telescopically moved synchronously (the sliding rod 302 slides inside the guide cylinder 303), and the horizontal plate 201 and the vertical plate 205 are always supported in a triangular state.

[0078] Specific reference Figure 5 and Figure 6 The foundation pit support assembly 50 includes a transverse inner support member 501, which is arranged inside the trench and has a reinforcement portion 502 installed on one side. The reinforcement portion 502 conflicts with the trench slope and extends to the inside of the trench slope through multiple sets of metal protrusions 503. The other side of the transverse inner support member 501 is hollow and has a transverse jack 504 installed on the inside; a transverse moving member 505, which is arranged on the other side of the transverse inner support member 501 and has an inner groove 5051 on the side close to the transverse jack 504. The inner groove 5051 is connected to the output end of the transverse jack 504. A transverse groove 506 is provided at the top of the connection between the support member 501 and the transverse moving member 505, and the transverse groove 506 is arranged on the outside of the transverse jack 504. A reinforcement part 502 is installed on the side of the transverse moving member 505 away from the inner groove 5051, and multiple groups of metal protrusions 503 on the side of the reinforcement part 502 are pressed against the other side of the groove slope. In addition, there are two groups of transverse inner support members 501 and transverse moving members 505, and a longitudinal connecting assembly 507 is provided between the two groups of transverse inner support members 501 and transverse moving members 505. Side support assemblies 60 are installed on the top of the transverse inner support members 501 and the transverse moving members 505.

[0079] In conjunction with the above-mentioned transverse internal support structure, the longitudinal connecting assembly 507 includes a longitudinal internal support member 5071, which is installed on the inner side of the transverse internal support member 501 and the transverse moving member 505, and a longitudinal jack 5072 is installed on the side away from the transverse internal support member 501 and the transverse moving member 505, wherein the output end of the longitudinal jack 5072 extends to the outer side of the longitudinal internal support member 5071 and is connected to a longitudinal moving member 5073, which is installed on the inner side of the transverse internal support member 501 and the transverse moving member 505, and wherein a longitudinal groove 5074 is provided at the top of the connection between the longitudinal internal support member 5071 and the longitudinal moving member 5073, and the longitudinal groove 5074 is arranged on the outer side of the longitudinal jack 5072.

[0080] In this solution, the longitudinal jack 5072 can operate to drive the longitudinal moving part 5073 connected to its output end to move, so that the transverse inner support part 501 and the transverse moving part 505 connected to the longitudinal moving part 5073 can move longitudinally and contact the inner wall of the groove to realize the installation and fixing operation.

[0081] In the trench excavation support equipment for improving slope stability of the present invention, when the foundation pit support assembly 50 is installed inside the trench under construction, the transverse jack 504 can be operated to drive the transverse moving member 505 connected to its output end to move telescopically. The adjustment is based on the corresponding trench size, so that the transverse moving member 505 and the multiple sets of metal protrusions 503 provided on the side of the transverse inner support member 501 can extend into the soil layer on the inner wall of the trench, and the longitudinal movement of the transverse moving member 505 and the transverse inner support member 501 can be coordinated to achieve the entire installation operation. The design of the longitudinal groove 5074 and the transverse groove 506 can expand the space of the longitudinal jack 5072 and the transverse jack 504, facilitating the telescopic movement operation for extracting air for lifting, and at the same time allowing workers to observe the operating status of the two in real time.

[0082] Specific reference Figure 7 and Figure 8 The side support assembly 60 includes a side base 601, which is installed on the top of the horizontal moving member 505 and is internally rotatably connected to a bottom block 602 extending to the outside, and the bottom block 602 is installed on the bottom of the oblique jack 603 by screws; a connecting sleeve 604, the connecting sleeve 604 is connected to the output end of the oblique jack 603, and an oblique support arm 605 is installed on the side by screws, and the outer side of the oblique support arm 605 is rotatably connected to a sliding body 606, wherein the sliding body 606 is slidably connected to the inside of the embankment column 607, and the embankment column 607 is rotatably connected to the inner side of the rotating seat 608, and the rotating seat 608 is installed on the top of the horizontal inner support member 501 and is arranged close to the side of the reinforcement part 502.

[0083] In this embodiment, a guide rod 6071 is mounted at the center of the inner portion of the embankment column 607. A sliding body 606 is slidably connected to the outer side of the guide rod 6071. Support springs 6072 are disposed on the outer side of the guide rod 6071. The support springs 6072 are located on the upper and lower sides of the sliding body 606 and connected to the inner wall of the embankment column 607 via damping blocks. The design of the support springs 6072 provides support and cushioning for the upward and downward movement of the sliding body 606, reducing the degree of damage to the tilt jack 603 caused by impact forces and thereby increasing the service life of the tilt jack 603. Furthermore, the sliding body 606 can telescope within the embankment column 607, facilitating adjustment of the angle of the embankment column 607 and enabling support operations on trench inner walls with varying inclination angles.

[0084] In the trench excavation support device for improving slope stability of the present invention, when the support device is installed within the trench, the movement of the transverse moving member 505 drives the side base 601 mounted on top of it to move, allowing the bottom block 602 and the diagonal jack 603, which are rotatably connected via the side base 601, to rotate. Simultaneously, as the diagonal jack 603 rotates, the diagonal support arm 605, connected to its output end via the connecting sleeve 604, drives the sliding body 606, which is rotatably connected to its outer side, to move telescopically, ensuring a triangular support state for the dike column 607 and improving the supporting capacity of the dike column 607.
