Description

Technical Field

[0001] This invention relates to slope protection technology, and more particularly to a slope protection arch frame. Background Technology

[0002] In the field of slope protection, arch frames (arch-shaped skeletons) are a commonly used slope protection technology, which can both stabilize the slope and resist erosion. An arch frame is composed of multiple arch units. One of the functions of the longitudinal beams on both sides of the arch unit is to guide water, draining rainwater from the top of the slope and the arch; the function of the arch beams is to intercept rainwater in the arch and then guide it into the longitudinal beams.

[0003] Precast block arches are assembled from different precast components to form an arch unit. In the early days, a large number of precast blocks were used. For example, according to the scheme disclosed in Chinese patent document CN 110565659 A, there are 5 types of blocks and 28 blocks are assembled, namely the "5+28" combination scheme.

[0004] In recent years, large-sized components have gradually replaced small-sized components. The solution disclosed in Chinese patent document CN 217870548 U uses three types of components and requires eight pieces to be assembled, i.e., a "3+8" combination; the solution disclosed in Chinese patent document CN211735446 U uses two types of components and requires four pieces to be assembled, i.e., a "2+4" combination, which greatly reduces the number of pieces to be assembled.

[0005] All the above solutions strive to reduce the number of splices and the types of components. Theoretically, an arch unit requires at least two spliced ​​components of one type, i.e., a "1+2" ​​combination. This is the limit in terms of quantity. The following six types of single components can each be spliced ​​into an arch unit, with a splicing quantity of 2, such as... Figure 1 As shown. However, the single component has a complex shape, is bifurcated, and has large horizontal and vertical dimensions, resulting in complex molds, difficult processing, and difficult transportation, making it impractical in reality.

[0006] The existing precast block arch frames have the following problems: 1. Either the number of splices is large and the construction is complicated, or the number of components is small and the shape is complicated; 2. Water seepage at the joints of components; 3. When the rain is heavy, the drainage capacity of the drainage channel is insufficient, resulting in overflow, rainwater flows into the slope, causing the soil to soften and the slope to collapse. Summary of the Invention

[0007] The purpose of this invention is to provide a two-component slope protection arch frame, which is composed of an optimized "2+3" scheme, resulting in fewer splices, fewer component types, and simpler shapes.

[0008] To address this, the present invention provides a two-component slope protection arch frame, comprising two types of components: an arch beam and longitudinal beams. During installation, the components are embedded into the slope, with their top surfaces flush with the slope surface. Both the arch beam and longitudinal beams are single strip structures. The longitudinal beam includes a body, a water-retaining edge, an upper connecting part, a lower connecting part, a left connecting part, and a right connecting part. The water-retaining edge is located on both sides of the top surface of the body, forming a water-guiding channel. The left and right connecting parts are located on both sides of the longitudinal beam, where the water-retaining edge is interrupted at the left and right connecting parts. The arch beam includes a body, a water-retaining edge, a left connecting part, and a right connecting part. The number of components constituting an arch unit is three: one arch beam and two longitudinal beams. The left connecting part of the arch beam is spliced ​​to the right connecting part of the longitudinal beam, and the right connecting part of the arch beam is spliced ​​to the left connecting part of the longitudinal beam. In the two spliced ​​longitudinal beams, the lower connecting part of longitudinal beam one is spliced ​​to the upper connecting part of longitudinal beam two.

[0009] Compared with existing precast block arch frames, the present invention has the following technical advantages / effects:

[0010] 1. This invention employs two components, meaning there are two types of components. The two components are similar in size and shape, with a single strip component having a large aspect ratio and requiring three joints. Among single strip components with a large aspect ratio, the minimum number of joints is 3, making the "2+3" combination the optimal solution. The strip component simplifies the component shape, avoiding a "branching" effect, thus simplifying the mold, making the product easier to process, facilitating transportation, reducing joints, speeding up construction, and lowering costs.

[0011] 2. Traditional component splicing generally uses a cement mortar bedding layer for connection. With slight deformation and settlement of the slope, the bedding layer will break, and the components will easily loosen and collapse, losing their protective function. The comparative technology uses a mortise and tenon splicing structure. Although the components are not easy to loosen, rainwater seeps into the soil through the splicing joints, leading to soil erosion and arch collapse. Compared with the comparative technology, the present invention uses a seepage-proof mortise and tenon structure, which does not require mortar connection. The joints are beautiful, the connection strength is improved, and rainwater cannot enter the slope through the joints.

[0012] 3. One of the functions of the arch frame is to collect and guide rainwater. When the amount of rainwater increases, the rainwater will overflow from the drainage channel of the arch frame, eventually leading to soil erosion, slope settlement, and arch frame collapse. The present invention adopts a "three-dimensional drainage" structure. Rainwater at the top of the slope is first discharged from the internal drainage cavity of the longitudinal beam. When the amount of rainwater increases, the water flows away from the drainage channel, the drainage volume is multiplied, and the infiltration of rainwater into the soil is reduced.

[0013] In addition to the objectives, features, and advantages described above, the present invention has other objectives, features, and advantages. The invention will now be described in further detail with reference to the figures. Attached Figure Description

[0056] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0057] Example 1

[0058] Combined with reference Figures 2 to 4 The two-component slope protection arch frame in this embodiment includes two types of components, namely longitudinal beam 10 and arch beam 20. The components are embedded into the slope body during installation, and the top surface of the components is flush with the slope surface.

[0059] Both longitudinal beam 10 and arch beam 20 are single strip structures. Longitudinal beam 10 is a straight strip, while arch beam 20 is a curved strip, and neither has branches.

[0060] The longitudinal beam 10 includes a longitudinal beam body 11, a longitudinal beam water-blocking edge 12, an upper connecting part 13, a lower connecting part 14, a left connecting part 15, and a right connecting part 16. The longitudinal beam water-blocking edge 12 is provided on both sides of the top surface of the longitudinal beam body 11 and forms a water guiding channel. The left connecting part 15 and the right connecting part 16 are symmetrically provided on both sides of the longitudinal beam, for example, at the middle or waist position of the longitudinal beam along the length direction. At the left and right connecting parts, the longitudinal beam water-blocking edge 12 is interrupted.

[0061] The arch beam 20 includes an arch beam body 21, an arch beam water-retaining edge 22, a left end joint 23, and a right end joint 24. The arch beam 20 is placed laterally during assembly, with the arch beam water-retaining edge 22 located below the top surface of the body. The joint surfaces of the left and right end joints of the arch beam 20 are both longitudinal end faces, meaning that these longitudinal end faces are parallel to the longitudinal beam body.

[0062] Each arch consists of three components: one arch beam 20 and two longitudinal beams 10. During assembly, the left end joint 23 of the arch beam is joined to the right end joint 16 of the longitudinal beams, and the right end joint 24 of the arch beam is joined to the left end joint 15 of the longitudinal beams. Simultaneously, the arch beam's water-retaining edge 22 connects to the longitudinal beam's water-retaining edge 12 located below the left / right end joints, thus guiding rainwater collected along the arch beam's water-retaining edge into the longitudinal beam's drainage channel.

[0063] In the two longitudinal beams that are spliced ​​together, the lower connecting part 14 of longitudinal beam one is spliced ​​with the upper connecting part 13 of longitudinal beam two.

[0064] Compared with existing multi-arch or single-component arch splicing methods, the two-component slope protection arch frame of this invention has the best overall effect: there are only two types of components, and the shapes are simplified, all of which are strip structures without branches. This results in fewer types of component molds and simpler structures, leading to lower component manufacturing costs; it is also convenient to transport and quick to hoist and install.

[0065] Example 2

[0066] Combined with reference Figures 5 to 7 In this embodiment, a waterproof mortise and tenon joint structure 100 is formed between the longitudinal beams. A waterproof mortise and tenon joint structure 200 is formed between the arch beam and the longitudinal beam.

[0067] In the first type of seepage-proof mortise and tenon joint structure 100, the first joint includes a first top cover 101 and two first locking grooves 102 located on the upper layer. The two first locking grooves 102 are symmetrically opened on opposite sides of the first top cover 101. The second joint includes a first seepage-proof bottom plate 103, a first seepage-proof sidewall 104, and two first locking posts 105 located on the lower layer. The first seepage-proof sidewall 104 is located on the left / right side of the first seepage-proof bottom plate 103 and is arranged on the same side as the longitudinal beam water-retaining edge 12. Its top is flush with the longitudinal beam water-retaining edge 12 and becomes an integral part. The two first locking posts 105 are located above the first seepage-proof bottom plate 103 and are arranged symmetrically on the left and right. When the two components are spliced, the locking grooves and locking posts can be vertically inserted together. The first top cover 101 covers the first seepage-proof bottom plate 103. In the slope application scenario (slope), the upper edge of the top surface of the seepage-proof bottom plate is higher than the joint line, thus forming a seepage-proof mortise and tenon joint structure.

[0068] In the second type of anti-seepage mortise and tenon joint structure 200, the connecting part on the arch beam 20 includes a second top cover 201, the end of which forms a second tenon 202. The connecting part on the longitudinal beam 10 includes a second anti-seepage bottom plate 203 extending outward from the inside of the longitudinal beam body 11 and a second anti-seepage side wall 204 located on the lower side of the second anti-seepage bottom plate. The second anti-seepage side wall 204 is at the same height as the water-blocking edge 12 of the longitudinal beam and forms an integral part. The second anti-seepage side wall 204 on the lower side and the water-blocking edge 12 on the upper side of the longitudinal beam form a second mortise groove 205 that is smaller on the outside and larger on the inside. When the two components are spliced, the second top cover 201 covers the second anti-seepage bottom plate 203, and the second tenon 202 and the second mortise groove 205 can be vertically inserted together to form an anti-seepage mortise and tenon joint structure.

[0069] In this embodiment, the upper cover directly covers the lower impermeable base plate, achieving the purpose of preventing water seepage. In one example, a layer of polymer mixture slurry is brushed onto the impermeable base plate, and after solidification, the leakage gap between the top cover and the impermeable base plate is blocked. In another example, in the slope application scenario (slope), the upper edge of the top surface of the impermeable base plate is higher than the joint line, so that rainwater entering the leakage gap will not flow back into the slope.

[0070] Example 3

[0071] Combined with reference Figures 8 to 10 In this embodiment, a waterproof mortise and tenon joint structure 300 is formed between the longitudinal beams. A waterproof mortise and tenon joint structure 400 is formed between the arch beam and the longitudinal beam.

[0072] In the anti-seepage mortise and tenon joint structure 300, the first joint of the longitudinal beam is located on the upper layer, including the third top cover 301 and two third locking posts 302 located on the side walls of the third top cover. The water-blocking edge extends continuously above the longitudinal beam body 11 and the third top cover 301. The third locking post 302 is a protruding structure protruding from the side of the top cover. The second joint is located on the lower layer, including the third anti-seepage bottom plate 303 and two third ear seats 304 located on both sides of the third anti-seepage bottom plate. The third anti-seepage bottom plate 303 and the third top cover 301 are both the same width as the longitudinal beam body 11. The two third ear seats 304 are symmetrically arranged on both sides of the third anti-seepage bottom plate 303 and are higher than the third anti-seepage bottom plate 303. Each ear seat in the two third ear seats 304 has a third locking groove 305 on its inner side wall. A pair of third locking posts 302 and a pair of third locking grooves 305 can be vertically inserted together. The top cover just covers the anti-seepage bottom plate, thus forming an anti-seepage mortise and tenon joint structure.

[0073] In the anti-seepage mortise and tenon joint structure 400, the connecting part on the arch beam includes a fourth top cover 401, the end of which forms a fourth tenon 402. The connecting part on the longitudinal beam includes a fourth anti-seepage base plate 403 extending outward from the side of the longitudinal beam body 11, and an upper anti-seepage side wall 404a and a lower anti-seepage side wall 404b located on the upper and lower sides of the fourth anti-seepage base plate. The lower anti-seepage side wall 404b is at the same height as the water-blocking edge 12 of the longitudinal beam and forms an integral part. The lower anti-seepage side wall 404b and the upper anti-seepage side wall 404a form a fourth mortise groove 405 that is smaller on the outside and larger on the inside. When the two components are spliced, the fourth top cover 401 covers the fourth anti-seepage base plate 403, and the fourth tenon 402 and the fourth mortise groove 405 can be vertically inserted together to form a mortise and tenon joint structure.

[0074] The longitudinal beam body 11 has a longitudinal drainage cavity 17 inside, and the longitudinal drainage cavity 17 is connected in the upper and lower longitudinal beams that are spliced ​​together.

[0075] In this embodiment, the longitudinal drainage channel 17 is a row of circular cross-section channels, and the longitudinal drainage channel 17 only penetrates the fourth top cover 401.

[0076] Example 4

[0077] like Figure 11 and Figure 12 As shown, in this embodiment, the longitudinal drainage channel 17 passes through both the third top cover 301 and the third seepage-blocking bottom plate 303. At this time, only the upper half 17a of the longitudinal drainage channel 17 is retained on the top cover, and the lower half 17b is retained on the third seepage-blocking bottom plate 303. When the third top cover 301 and the third seepage-blocking bottom plate 303 are stacked together, there will be gaps in the drainage channel at the interface, resulting in leakage.

[0078] To solve this problem, for example... Figure 11As shown, in this embodiment, a conduit 18 is introduced into one side of the top cover and inserted into the longitudinal drainage channel 17, so that a closed channel is formed under the top cover, which can prevent leakage from the interface gap.

[0079] Example 5

[0080] This embodiment provides a seepage-proof mortise and tenon joint structure 500, which can be used for the connection between longitudinal beams and longitudinal beams, as well as for the connection between longitudinal beams and arch beams.

[0081] Combined with reference Figure 13 and Figure 14 In the mortise and tenon joint structure 500, the first joint consists of two layers: the upper layer is the fifth top cover 501, and the lower layer is the mortise and tenon structure 502. The second joint only has a lower layer, which includes a fifth seepage-blocking bottom plate 503 and a mortise and tenon structure 504. The mortise and tenon structure 504 is located at the front end of the fifth seepage-blocking bottom plate 503. For clarity of view, the original seepage-blocking sidewalls on both sides of the fifth seepage-blocking bottom plate 503 have been removed.

[0082] exist Figure 13 In the middle, the first mortise and tenon structure 502 is a dovetail tenon, and the second mortise and tenon structure 504 is a dovetail groove. When the two components are spliced, they can be vertically inserted together to form a mortise and tenon joint structure. The top cover covers the seepage-proof bottom plate and the mortise and tenon joint structure, thus forming a seepage-proof mortise and tenon joint structure.

[0083] exist Figure 14 In the middle, the first mortise and tenon structure 502 is a dovetail groove, and the second mortise and tenon structure 504 is a dovetail tenon. When the two components are spliced, they can be vertically inserted together to form a mortise and tenon joint structure. The top cover covers the seepage-proof bottom plate and the mortise and tenon joint structure, thus forming a seepage-proof mortise and tenon joint structure.

[0084] Example 6

[0085] Combined with reference Figure 15 and Figure 16 In this embodiment, the lower connecting part 14 of the longitudinal beam includes two first connecting lugs 141 symmetrically arranged on the left and right sides of the outer side of the longitudinal beam body 11, and the upper connecting part 13 includes two second connecting lugs 142 symmetrically arranged on the left and right sides of the outer side of the longitudinal beam body 11. When the two longitudinal beams are spliced ​​together, a pair of first connecting lugs 141 and a pair of second connecting lugs 142 are fixedly connected together by bolts.

[0086] In addition, arch beams and longitudinal beams can be connected by mortise and tenon joints or by concealed mortise and tenon joints with a top cover.

[0087] Example 7

[0088] Combined with reference Figures 17 to 19The arch frame in this embodiment includes a top beam 30. The top beam 30 is located at the top of the slope and guides the rainwater collected at the top of the slope into the drainage channel of the longitudinal beam for discharge. When the longitudinal beam is provided with a longitudinal drainage cavity 17, the rainwater is preferentially guided into the longitudinal drainage cavity 17. When the rainwater is not discharged in time, it is diverted and discharged by the drainage channel.

[0089] A seepage-proof connection can be achieved between the top beam and the longitudinal beams. Among them, Figure 17 The diagram shows a mortise and tenon joint structure 100 between the top beam 30 and the longitudinal beam 10 to prevent seepage. Figure 18 and Figure 19 This illustrates a waterproof mortise and tenon joint structure 300 formed between the top beam 30 and the longitudinal beam 10. The difference between the two lies in the fact that, in... Figure 18 In the middle section, the longitudinal drainage cavity 17 of the longitudinal beam is located above the impermeable bottom slab, and rainwater from the top beam is introduced into the longitudinal drainage cavity 17 through the slope. Figure 19 In the middle, the lower half 17b of the longitudinal drainage cavity 17 is opened on the seepage-proof bottom plate of the longitudinal beam, and the rainwater from the top beam is introduced into the lower half 17b through the slope.

[0090] In addition to the top beam, a sloping top can also be cast in place, leaving a drainage interface to connect with the connecting part on the longitudinal beam, so that the rainwater collected on the sloping top can be discharged through the longitudinal drainage cavity 17.

[0091] Example 8

[0092] Combined with reference Figures 20 to 22 The difference between this embodiment and embodiment two is that a longitudinal drainage channel 17 is also provided in the longitudinal beam 10. Only the upper half 17a of the longitudinal drainage channel 17 is retained on the first top cover 101, and only the lower half 17b is retained on the first seepage-blocking bottom plate 103.

[0093] The above description is merely an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

The seepage-blocking bottom plate and the top cover are the same width as the main body. The mortise and tenon structure 5 is a pair of locking pins, and the mortise and tenon structure 6 is a pair of ear seats. The ear seats are located on both sides of the seepage-blocking bottom plate and are higher than the seepage-blocking bottom plate. The inner side wall of the ear seats is provided with locking grooves. The locking pins and locking grooves can be vertically inserted together. The top cover just covers the seepage-blocking bottom plate, thus forming a seepage-proof mortise and tenon joint structure.

6. The two-component slope protection arch frame according to any one of claims 1 to 5, characterized in that, The longitudinal beam has a longitudinal drainage channel running through the entire beam. In the spliced ​​longitudinal beams, the longitudinal drainage channels are connected to each other to discharge rainwater collected at the top of the slope.

7. The two-component slope protection arch frame according to claim 6, characterized in that, The longitudinal drainage channel is a row of circular cross-section channels. The lower connecting part of the longitudinal beam has a top cover, and the upper connecting part of the longitudinal beam has a seepage-blocking bottom plate. The longitudinal drainage channel only penetrates the top cover, or the longitudinal drainage channel penetrates both the top cover and the seepage-blocking bottom plate.

8. The two-component slope protection arch frame according to claim 7, characterized in that, When the longitudinal drainage channel passes through both the top cover and the bottom plate, a conduit is provided on one side of the top cover. The conduit is inserted into the longitudinal drainage channel, so that a closed channel is formed below the top cover.

9. The two-component slope protection arch frame according to claim 6, characterized in that, Between the spliced ​​arch beams and longitudinal beams, the joints form a seepage-proof mortise and tenon joint structure. In this structure, the joint on the arch beam includes a top cover, the end of which forms a tenon. The joint on the longitudinal beam has two types. The first type includes a seepage-blocking bottom plate extending outward from the side of the longitudinal beam body and seepage-proof sidewalls located on the upper and lower sides of the bottom plate. The lower seepage-proof sidewall is at the same height as the water-retaining edge of the arch beam and forms an integral part therewith. This lower seepage-proof sidewall is integrated with the upper seepage-proof sidewall. The first type of joint consists of a tenon and mortise structure with a smaller outer surface and a larger inner surface, i.e., a mortise and tenon groove. The second type of joint includes a seepage-blocking bottom plate extending outward from the inside of the longitudinal beam body and a seepage-proof side wall located on the lower side of the seepage-blocking bottom plate. The seepage-proof side wall on the lower side is at the same height as the water-blocking edge of the arch beam and forms an integral part. The seepage-proof side wall on the lower side and the water-blocking edge of the longitudinal beam on the upper side form a tenon and mortise structure with a smaller outer surface and a larger inner surface, i.e., a mortise and tenon groove. When the two components are spliced, the top cover just covers the seepage-blocking bottom plate, and the tenon and mortise and tenon groove can be vertically inserted together to form a tenon and mortise mating structure.

10. The two-component slope protection arch frame according to claim 6, characterized in that, The longitudinal beams that are spliced ​​together are fixedly connected by bolts.
