Description

Technical Field

[0001] The invention relates to the technical field of construction devices, in particular to a soil hole reinforcement and support device. Background Art

[0002] Soil caves are special geological structures formed by the overlying layer of soluble rock strata under the action of subsidence. Their formation requires the presence of soil layers that are easily eroded, underground water flow channels, and dynamic conditions of frequent water level fluctuations. Soil cave reinforcement is achieved by providing certain support and reinforcement to the soil layer at the top of the soil cave to prevent the soil layer from collapsing and causing the soil cave to be buried. The soil layer is supported and reinforced by an arc-shaped support device to improve the stability inside the soil cave.

[0003] However, when the support device is reinforcing the soil hole, the support plate is fitted on the soil hole, and the support rod is placed in the middle of the soil hole to provide vertical support for the support plate at the upper end of the soil hole. The middle support rod easily divides the space of the soil hole into two channels on the left and right. The soil hole channel is too small to facilitate people to pass through the middle of the soil hole. In addition, the support plate is fitted at the upper end of the soil hole, and there is a gap in the connection between the support plates. The vibration generated during the excavation of the soil hole can easily cause the soil to fall from the gap, which can easily cause the pressure of the soil on the support plate to be unbalanced. As a result, the soil in some positions has a greater squeezing force on the support plate, which can easily bend the support plate, thereby causing the collapse of the soil hole. Summary of the Invention

[0004] The present invention provides a soil hole reinforcement and support device, which overcomes the deficiencies described in the background art.

[0005] The technical solution adopted by the present invention to solve its technical problem is: A soil hole reinforcement and support device includes a support plate, a fastening structure, a support structure, and an arc-shaped plate. The arc-shaped plate is fixed to the upper end of the support structure through the support plate. The fastening structure is arranged in an arc shape outside the arc-shaped plate and is disposed on the upper end of the support structure. The fastening structure abuts against the outer side of the arc-shaped plate. When the soil in the soil hole presses the fastening structure, the fastening structure presses the outer side of the arc-shaped plate. The fastening structure is provided with a force-bearing structure and a compression structure. Adjacent force-bearing structures are connected in an arc shape through the compression structure. The compression structure is against the outside of the arc plate. The arc plate is provided with holes corresponding to the position of the support plate. The two ends of the arc plate are fastened through the holes. When the force-bearing structure is squeezed by the soil, the force-bearing structures shrink and move closer together, and the compression structure is elastically pressed against the outside of the arc plate.

[0006] A better technical solution: The force-bearing structure is provided with a triangular block, a conversion structure and a force-bearing plate. The triangular block is arranged on the outside of the force-bearing plate. The side of the force-bearing plate is provided with a trapezoidal hole groove corresponding to both sides of the conversion structure. The conversion structure is pressed against the outside of the arc plate through the compression structure.

[0007] A better technical solution: The conversion structure is provided with a fixed bar, a first spring, a trapezoidal plate, an inclined block and a sliding rod. The fixed bar slides on the side of the trapezoidal plate through the inclined block. The sliding rod is connected to the side of the inclined block. The inclined block slides on the side of the trapezoidal plate through the sliding rod, and causes the sliding rod to squeeze the first spring. When squeezing between adjacent force-bearing plates, the fixed bar is driven to tilt and squeeze the trapezoidal plate. At this time, the sliding rod slides on the inner side of the trapezoidal plate and compresses the first spring, so that the trapezoidal plate drives the compression structure to press against the outer side of the arc plate.

[0008] A better technical solution: The compression structure is provided with an elastic plate, an inclined plate, a hollow structure and a connecting plate. The elastic plate is fitted between the connecting plate and the inclined plate, and the hollow structure is located inside the elastic plate. Under the extrusion of the trapezoidal plate, the connecting plate elastically presses the inclined plate against the outer side of the arc plate through the hollow structure.

[0009] A better technical solution: the elastic plate is provided with a metal plate, a load-bearing plate and a second spring, the second spring is connected to the inner side of the load-bearing plate and the metal plate, the load-bearing plate and the metal plate are arranged on the outer side of the load-bearing plate, when the soil in the soil hole squeezes the load-bearing plate, under the support of the metal plate, the load-bearing plate deforms inward and compresses the second spring.

[0010] A better technical solution: The support structure is provided with a deformation plate, an opening plate, a sealing plate and a triangular bar. The deformation plate is arranged on the side of the opening plate, and a triangular bar for arranging lamps is provided on the outside of the deformation plate. The sealing plate is attached to the inner side of the deformation plate, and the sealing plate forms a sealing state on the inner side of the opening plate. When the deformation plate bends inward, the sealing plate is compressed and buffered in the opening plate.

[0011] Compared with the existing technology, this technical solution has the following advantages: When the soil squeezes the stress-bearing structure in the present invention, the stress-bearing plates move and squeeze relative to each other, and then the fixed bar squeezes the trapezoidal plate through the inclined block. At this time, the inclined block drives the sliding rod to slide in the trapezoidal plate and compresses the first spring, so that the trapezoidal plate moves toward the compression structure under the squeezing of the inclined inclined block, so that the trapezoidal plate drives the compression structure to squeeze the outside of the arc plate, so that each stress-bearing plate is relatively fastened, and the soil pressure on the outside of the stress-bearing plate is converted into a uniform resistance pressure on the outside of the arc plate, preventing the outside of the arc plate from being easily deformed due to uneven soil pressure, so that the soil in the soil hole avoids the generation of gaps and squeezing balance under the tightening of the fastening structure, and prevents the soil in some positions from exerting a large squeezing force on the support plate, which easily bends the support plate and causes collapse.

[0012] When the soil is squeezed inward on the outside of the deformable plate, the deformable plate generates a downward gravity on the triangular bar through the supporting force of the triangular bar on the soil, and elastically moves toward the sealing plate through the deformable plate. The pressure of the soil is buffered under the sealing buffer of the sealing plate, and a downward stabilizing force is generated under the gravity of the soil supported by the straight edge of the triangular bar and the downward pressure of the soil gravity of the arc plate, thereby preventing the opening plate from being easily detached under the squeezing of the soil, and providing support for the soil above the arc plate.

DETAILED DESCRIPTION

[0022] like Figures 1 to 7As shown, the present invention proposes a soil hole reinforcement and support device, including a support plate 1, a fastening structure 2, a support structure 3 and a curved plate 4. The curved plate 4 is fixed to the upper end of the support structure 3 through the support plate 1. The fastening structure 2 is arranged in an arc shape on the outside of the curved plate 4 and is provided on the upper end of the support structure 3. The fastening structure 2 is against the outside of the curved plate 4. When the soil in the soil hole presses the fastening structure 2, the fastening structure 2 presses the outside of the curved plate 4. The fastening structure 2 is provided with a force-bearing structure 21 and a compression structure 22. Adjacent force-bearing structures 21 are connected in an arc shape through the compression structure 22. The compression structure 22 is against the outside of the arc plate 4. The arc plate 4 is provided with holes 401 corresponding to the position of the support plate 1. The two ends of the arc plate 4 are fastened through the holes 401. When the force-bearing structure 21 is squeezed by the soil, the force-bearing structures 21 shrink and move closer together, and the compression structure 22 elastically presses against the outside of the arc plate 4.

[0023] In addition, the load-bearing structure 21 is assembled through the compression structure 22. When the load-bearing structure 21 is subjected to the soil pressure of the soil hole, the load-bearing structure 21 is compressed inward. At this time, the soil pressure exerted on the load-bearing structure 21 is converted into the resistance force of the compression structure 22 on the arc plate 4, thereby preventing the arc plate 4 from being easily deformed by the direct pressure of the soil.

[0024] Among them, the force-bearing structure 21 is provided with a triangular block 211, a conversion structure 212 and a force-bearing plate 213. The triangular block 211 is arranged on the outside of the force-bearing plate 213. The side of the force-bearing plate 213 is provided with a trapezoidal hole groove, corresponding to both sides of the conversion structure 212. The conversion structure 212 is pressed against the outside of the arc plate 4 through the compression structure 22.

[0025] Moreover, when the load-bearing plates 213 are subjected to soil squeezing force, the conversion structure 212 is squeezed by the load-bearing plates 213 on both sides, so that the load-bearing plates 213 move relatively and the conversion structure 212 is squeezed toward the compression structure 22, so that the pressure of the soil is converted into a uniform pressure of the compression structure 22 on the outer side of the arc plate 4.

[0026] Among them, the conversion structure 212 is provided with a fixed bar 41, a first spring 42, a trapezoidal plate 43, an inclined block 44 and a slide rod 45. The fixed bar 41 slides on the side of the trapezoidal plate 43 through the inclined block 44, and the slide rod 45 is connected to the side of the inclined block 44. The inclined block 44 slides on the side of the trapezoidal plate 43 through the slide rod 45, and causes the slide rod 45 to squeeze the first spring 42. When squeezing between adjacent force-bearing plates 213, the fixed bar 41 is driven to tilt and squeeze the trapezoidal plate 43. At this time, the slide rod 45 slides on the inside of the trapezoidal plate 43 and compresses the first spring 42, so that the trapezoidal plate 43 drives the compression structure 22 to press against the outside of the arc plate 4.

[0027] Furthermore, the fixing bar 41 is a trapezoidal structure, and is slidably mounted corresponding to the trapezoidal hole groove on the load-bearing plate 213 .

[0028] The first spring 42 is compressed against the first spring 43 and the first spring 43 is compressed against the first spring 43. The first spring 42 is compressed against the first spring 43 and the first spring 43 is compressed against the first spring 43. The first spring 42 is compressed against the first spring 43 and the first spring 43 is compressed against the first spring 43. The first spring 42 is compressed against the first spring 43 and the first spring 43 is compressed against the first spring 43. The first spring 42 is compressed against the first spring 43 and the first spring 43 is compressed against the first spring 43. The first spring 42 is compressed against the first spring 43 and the first spring 43 is compressed against the first spring 43.

[0029] Among them, the compression structure 22 is provided with an elastic plate 221, an inclined plate 222, a hollow structure 223 and a connecting plate 224. The elastic plate 221 is fitted between the connecting plate 224 and the inclined plate 222, and the hollow structure 223 is located inside the elastic plate 221. Under the extrusion of the trapezoidal plate 43, the connecting plate 224 elastically presses the inclined plate 222 against the outer side of the arc plate 4 through the hollow structure 223.

[0030] In addition, the elastic plate 221 is made of rubber and has a certain degree of deformation elasticity, and the hollow structure 223 is made of aluminum alloy and has the characteristics of toughness and a certain degree of elastic deformation. In the present invention, when the connecting plate 224 drives the inclined plate 222 to press against the outer side of the arc plate 4 through the elastic plate 221, the hollow structure 223 is compressed inside the elastic plate 221 and generates an outward sealing elastic pressure, so that the middle of the inclined plate 222 forms a greater pressing force than the two sides of the inclined plate 222, so that the inclined plate 222 diverts the pressure of the trapezoidal plate 43 to the outer side of the arc plate 4 , and then the compression structure 22 forms an arc-shaped uniformly distributed force point on the outside of the arc plate 4, so that the pressure of the soil on the force structure 21 is converted into a uniform resistance force of the compression structure 22 on the outside of the arc plate 4. When one of the compression structures 22 is subjected to the pressure of the conversion structure 212, the adjacent force plate 213 will squeeze the conversion structure 212 on the other side, so that the arc-shaped force structure 21 is evenly tightened inward, forming a uniform resistance force on the outside of the arc plate 4, avoiding the uneven distribution of soil pressure on the outside of the arc plate 4 and easily causing deformation.

[0031] Among them, the elastic plate 221 is provided with a metal plate 11, a load-bearing plate 12 and a second spring 13. The second spring 13 is connected to the inner side of the load-bearing plate 12 and the metal plate 11. The load-bearing plate 12 and the metal plate 11 are arranged on the outside of the load-bearing plate 213. When the soil in the soil hole squeezes the load-bearing plate 12, under the support of the metal plate 11, the load-bearing plate 12 deforms inward and compresses the second spring 13.

[0032] In addition, the load-bearing plate 12 is made of rubber. With the support of the metal plate 11, the load-bearing plate 12 is bent and compressed toward the second spring 13, so that the outer side of the load-bearing plate 12 forms a certain supporting force on the soil, preventing the soil from sliding easily outside the load-bearing plate 213 and generating a gap.

[0033] Among them, the supporting structure 3 is provided with a deformation plate 31, an opening plate 32, a sealing plate 33 and a triangular bar 34. The deformation plate 31 is arranged on the side of the opening plate 32, and a triangular bar 34 for arranging lamps is provided on the outside of the deformation plate 31. The sealing plate 33 is attached to the inner side of the deformation plate 31, and the sealing plate 33 forms a sealing state on the inner side of the opening plate 32. When the deformation plate 31 bends inward, the sealing plate 33 is compressed and buffered in the opening plate 32.

[0034] In addition, one of the right-angled sides of the triangular bar 34 is in a horizontal state, and the soil will form a downward gravity pressing effect on the right-angled side of the triangular bar 34, and a support plate 1 is fixed to the upper end of the opening plate 32, and the position of the opening plate 32 corresponding to the fastening structure 2 is hollow, which facilitates the insertion of the fastening structure 2 into the upper end of the opening plate 32.

[0035] In addition, the deformable plate 31 is made of aluminum alloy and has a certain deforming force. In the present invention, when the soil is squeezed inward on the outside of the deformable plate 31, the deformable plate 31 generates a downward gravity on the triangular bar 34 through the supporting force of the soil by the triangular bar 34, and elastically moves toward the sealing plate 33 through the deformable plate 31, buffering the pressure of the soil under the sealing buffer of the sealing plate 33, and generating a downward stabilizing force under the gravity of the soil supported by the straight edge of the triangular bar 34 and the downward pressure of the soil gravity of the arc plate 4, thereby preventing the opening plate 32 from being easily detached under the squeezing of the soil, and at the same time providing supporting force for the soil above the arc plate 4, so that the supporting structures 3 on both sides of the soil hole can provide support to the upper arc plate 4 while preventing it from falling off, thereby avoiding the soil hole being divided into two channels due to the support rod set below the middle of the arc plate 4.

[0036] The above description is merely a preferred embodiment of the present invention and therefore cannot be used to limit the scope of the present invention. In other words, equivalent changes and modifications made according to the scope of the present invention and the contents of the specification should still fall within the scope of the present invention.
