Description

Technical Field

[0001] This utility model relates to the field of mountain support technology, specifically to a bamboo retaining wall. Background Technology

[0002] As my country's infrastructure construction continues to extend into mountainous and hilly areas with complex terrain, highway, railway, power, wind power, and water conservancy projects are increasingly expanding into terrains with significant elevation differences and limited space. Construction in these terrains often requires large-scale excavation, slope cutting, backfilling, and leveling of the original landform to meet the requirements of project layout and construction platforms. These operations generate substantial amounts of excavated soil and accumulated loads, not only altering the original surface stability but also significantly increasing local stress concentration and the risk of slope instability. Especially during the rainy season or under loose soil conditions, slopes are highly susceptible to geological disasters such as landslides and collapses, directly threatening project safety and construction progress. Therefore, to ensure the smooth progress of construction in mountainous areas, effective slope support measures must be implemented simultaneously in the early stages of construction to maintain soil stability, limit slope displacement, and reduce the probability of disasters.

[0003] Retaining piles are a type of deep-buried support structure. As a major component of retaining walls, they are widely used in mountain support engineering due to their relatively simple construction, versatile materials, and wide applicability. By inserting single or multiple rows of piles into the soil, they can effectively resist lateral earth pressure, thereby improving the overall stability of the slope. Currently, the most commonly used types of retaining piles in engineering include cast-in-place concrete piles and steel pipe piles. Although these structures have a certain load-bearing capacity, their use in mountainous environments has many limitations: cast-in-place concrete piles have a complicated construction process, requiring on-site formwork, pouring, and curing, and are greatly affected by terrain and climate conditions; while steel pipe piles have a high assembly efficiency, their material and processing costs are high, and they are highly dependent on transportation and hoisting equipment. Utility Model Content

[0004] In view of this, the present invention provides a bamboo retaining wall to solve the problems of long construction period and high material cost of traditional retaining piles.

[0005] In a first aspect, this utility model provides a bamboo retaining wall, comprising:

[0006] A plurality of bamboo retaining piles are spaced apart along a mountain slope. Each bamboo retaining pile includes a bamboo pile body, a fastening mechanism, a tensioning mechanism, and an anchoring mechanism. The fastening mechanism surrounds the outer wall of the bamboo pile body, and the plurality of fastening mechanisms are spaced apart along the length of the bamboo pile body. The tensioning mechanism includes a locking device, a tensioning rope, and a cone. The locking device and the cone are respectively in contact with the two end faces of the bamboo pile body, and the locking device is connected to the cone through the tensioning rope. The anchoring mechanism includes a stay cable and a ground nail. The ground nail is fixed in the soil on the side of the pile, and the ground nail is connected to the fastening mechanism through the stay cable.

[0007] A retaining plate is provided between two adjacent original bamboo retaining piles, and the two ends of the retaining plate are respectively connected to the fastening mechanism on the two original bamboo retaining piles.

[0008] Beneficial effects

[0009] The tensioning mechanism applies prestress axially to the original bamboo pile, effectively compacting the pile structure, preventing cracking and deformation, and enhancing its resistance to lateral earth pressure. The inclined anchoring mechanism further restricts pile displacement through a combination of ground nails and inclined cables, thus increasing the support strength of the original bamboo retaining pile.

[0010] By introducing raw bamboo as the main structure of retaining piles, and utilizing its lightweight, high strength, renewable, and easy-to-process characteristics, the construction process of retaining walls is effectively simplified, the construction cycle is significantly shortened, and the rapid deployment and installation of retaining walls is achieved.

[0011] In one optional embodiment, the locking device includes a locking device and a cover plate, the cover plate abutting against the end face of the original bamboo stake, the locking device being connected to the side of the cover plate away from the original bamboo stake, one end of the tension rope being connected to the cone head, and the other end passing through the bamboo membrane of the original bamboo stake and the cover plate along the axis of the original bamboo stake, and being connected to the locking device.

[0012] Beneficial effects

[0013] After the tensioning rope passes through the bamboo membrane and cover plate axially, it is reliably connected to the locking device. The cover plate and cone head apply stable prestress to both ends of the original bamboo pile, which enhances the connection strength between the tensioning mechanism and the original bamboo pile, prevents damage to the end structure of the original bamboo pile, and facilitates the rapid assembly and arrangement of the original bamboo retaining pile during construction.

[0014] In one alternative embodiment, the tensioning rope is a prestressed steel cable.

[0015] In one alternative implementation, the ground nail is connected to a fastening mechanism near the top of the original bamboo stake.

[0016] In one optional embodiment, the ground stake includes: a bearing plate, an anchor plate, and a central rib, wherein one end of the bearing plate and the anchor plate are connected, the central rib is disposed on the anchor plate, and the central rib is connected to the bearing plate.

[0017] In one alternative embodiment, the thickness of the anchor plate gradually decreases from the end closest to the bearing plate to the end furthest from the bearing plate.

[0018] Beneficial effects

[0019] The thickness of the anchor plate gradually decreases, which enhances the anchor plate's embedding ability in the soil, increases the frictional resistance between it and the surrounding soil, improves the anchoring effect of the ground nail, and prevents the ground nail from being pulled out of the soil or slipping.

[0020] In one alternative embodiment, a connecting hole is provided on the central rib, one end of the stay cable is connected to the connecting hole, and the other end is connected to the fastening mechanism.

[0021] In one optional embodiment, the fastening mechanism includes: a pair of arc-shaped clamps and fastening bolts, the inner wall of the arc-shaped clamps fitting against the internodes of the original bamboo pile, and the lower end of the arc-shaped clamps being engaged with the bamboo nodes of the original bamboo pile, the two ends of the arc-shaped clamps having through holes, and the fastening bolts passing through the through holes of the pair of arc-shaped clamps and connecting to the pair of arc-shaped clamps.

[0022] Beneficial effects

[0023] The inner wall of the arc-shaped clamp fits snugly against the nodes of the original bamboo pile, enhancing the fit and friction between the clamp and the bamboo. Its lower end is secured to the bamboo node, utilizing the natural protrusion structure of the bamboo node to form an axial stop, preventing the clamp from sliding along the pile axis and preventing the original bamboo from splitting.

[0024] In one alternative embodiment, the radius of the arc-shaped clamp is smaller than the internode radius of the original bamboo stake.

[0025] Beneficial effects

[0026] The clamp can form a certain pre-tightening force on the internodes of the original bamboo stake, which enhances the adhesion and friction between the fastening mechanism and the original bamboo stake. It can also be applied to original bamboo stakes with different internode sizes.

[0027] In one alternative embodiment, the retaining plate is a metal retaining plate. Attached Figure Description

[0040] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0041] The following is combined Figures 1 to 8 The following describes embodiments of the present invention.

[0042] According to an embodiment of the present invention, a bamboo retaining wall is provided, comprising: bamboo retaining piles 1 and retaining plates 2. Multiple bamboo retaining piles 1 are spaced apart along a mountain slope. Each bamboo retaining pile 1 includes: a bamboo pile body 11, a fastening mechanism 12, a tensioning mechanism 13, and an anchoring mechanism 14. The fastening mechanism 12 surrounds the outer wall of the bamboo pile body 11, and multiple fastening mechanisms 12 are spaced apart along the length of the bamboo pile body 11. The tensioning mechanism 13 includes a locking device 131, a tensioning rope 132, and a cone head 1. 33. The locking device 131 and the cone head 133 respectively abut against the two ends of the original bamboo pile body 11, and the locking device 131 is connected to the cone head 133 through the tension rope 132. The anchoring mechanism 14 includes: a cable 141 and a ground nail 142. The ground nail 142 is fixed in the soil on the side of the pile, and the ground nail 142 is connected to the fastening mechanism 12 through the cable 141. A set of retaining plates 2 is set between two adjacent original bamboo retaining piles 1. The two ends of the retaining plates 2 are respectively connected to the fastening mechanism 12 on the two original bamboo retaining piles 1.

[0043] The original bamboo stake 11 can be made of moso bamboo, which has a natural internode structure 112 and good axial strength. The fastening mechanism 12 is set on the outer wall of the internode 112 of the original bamboo stake 11, covering the outside of the internode 112 of the original bamboo stake 11, and multiple fastening mechanisms 12 are arranged at equal intervals along the length of the original bamboo stake 11.

[0044] The locking device 131 and the cone 133 are in close contact with the two ends of the original bamboo pile 11. The tension rope 132 connects the locking device 131 and the cone 133. By tensioning the tension rope 132, an axial tensile force is applied to the original bamboo pile 11, providing axial prestress to the original bamboo pile 11 and improving the load-bearing capacity of the original bamboo pile 11.

[0045] The anchoring mechanism 14 fixes the original bamboo pile 11 in the soil on the side of the slope where soil is piled up. The ground nail 142 is pre-embedded in the soil. One end of the inclined cable 141 is connected to the ground nail 142, and the other end is connected to the fastening mechanism 12 on the original bamboo pile 11, forming an inclined support structure, which effectively restricts the tilting and slippage of the original bamboo pile 11.

[0046] A set of retaining plates 2 are installed between two adjacent bamboo retaining piles 1. Multiple bamboo retaining piles 1 and retaining plates 2 are combined to form a closed or semi-closed bamboo retaining wall, which plays the role of blocking soil and sharing lateral pressure.

[0047] The original bamboo pile 11 is axially tensioned by a tensioning mechanism 13 to apply prestress, thereby improving the overall strength and compressive stability of the original bamboo pile 11 and effectively suppressing structural deformation. The anchoring mechanism 14 provides lateral support for the original bamboo pile 11 through the cooperation of ground nails 142 and stay cables 141, ensuring the stability and reliability of the original bamboo retaining wall under complex terrain conditions such as mountain slopes.

[0048] Bamboo retaining walls fully utilize the natural lightweight and high-strength properties of bamboo, making it not only readily available and inexpensive but also environmentally friendly and renewable, effectively reducing project costs. Furthermore, all components employ a prefabricated design, eliminating the need for heavy machinery during construction and making installation simple and quick, making it particularly suitable for mountainous areas with limited access.

[0049] In one embodiment, the locking device 131 includes a locking device 1311 and a cover plate 1312. The cover plate 1312 abuts against the end face of the original bamboo stake 11. The locking device 1311 is connected to the side of the cover plate 1312 away from the original bamboo stake 11. One end of the tension rope 132 is connected to the cone head 133, and the other end passes through the bamboo membrane 111 and the cover plate 1312 of the original bamboo stake 11 along the axis of the original bamboo stake 11 and is connected to the locking device 1311.

[0050] Specifically, the cover plate 1312 is directly attached to the upper end face of the original bamboo stake 11, serving as the mounting base for the wire locking device 1311. The wire locking device 1311 is located on the side of the cover plate 1312 away from the original bamboo stake 11, and is used to tighten and fix the tension rope 132. One end of the tension rope 132 is fixedly connected to the bottom surface of the cone head 133, and the other end passes through the inner bamboo membrane 111 and the cover plate 1312 along the central axis of the original bamboo stake 11, and is finally connected to the wire locking device 1311.

[0051] When assembling the original bamboo retaining pile 1, the tension rope 132 is tightened by tightening the locking device 1311 and pulling the cone head 133 in the axial direction of the original bamboo pile body 11, so that the cover plate 1312 and the cone head 133 apply pressure to the upper and lower end faces of the original bamboo pile body 11, so that the pile body is in a prestressed state and the overall strength of the original bamboo pile body 11 is increased.

[0052] In one embodiment, the tension rope 132 is a prestressed steel cable.

[0053] Specifically, prestressed steel cables have high strength and high elastic modulus mechanical properties, as well as good flexibility, making them easy to transport. They can apply continuous and stable tension force along the axis of the original bamboo pile 11, thereby improving the overall stiffness and compressive stability of the original bamboo retaining pile 1.

[0054] The prestressed steel cable not only enhances the connection strength between the tensioning mechanism 13 and the original bamboo pile 11, but also significantly improves the overall bearing capacity and durability of the original bamboo pile 11 under tension, reducing its deformation risk under slope lateral pressure.

[0055] In another embodiment, the tensioning rope 132 can also be made of galvanized steel wire rope. Galvanized steel wire rope has a multi-strand steel wire rope twisted structure, which has both high tensile strength and good corrosion resistance, and is suitable for outdoor humid or acidic / alkaline mountain environments.

[0056] In one embodiment, the fastening mechanism 12 includes a pair of arc-shaped clamps 121 and a fastening bolt 122. The inner wall of the arc-shaped clamps 121 is fitted with the internodes 112 of the original bamboo pile body 11, and the lower end of the arc-shaped clamps 121 is engaged with the bamboo nodes 113 of the original bamboo pile body 11. Through holes are opened at both ends of the arc-shaped clamps 121, and the fastening bolt 122 passes through the through holes of the pair of arc-shaped clamps 121 and is connected to the pair of arc-shaped clamps 121.

[0057] Specifically, the arc-shaped clamp 121 is made of metal, and its arc-shaped structure matches the outer surface of the internode 112 of the original bamboo pile 11. The inner wall of the arc-shaped clamp 121 fits against the position of the internode 112 of the original bamboo pile 11. Each pair of arc-shaped clamps 121 is symmetrically arranged on the outer periphery of the original bamboo pile 11 along the axis of the original bamboo pile 11. The lower end of the arc-shaped clamp 121 is engaged at the protruding bamboo node 113 of the original bamboo pile 11, and the naturally formed protrusion structure of the bamboo node 113 provides axial stop to prevent the clamp from sliding along the direction of the pile.

[0058] Each arc-shaped clamp 121 has through holes at both ends. A fastening bolt 122 passes through the through holes of a pair of arc-shaped clamps 121 and is locked with a nut, thereby firmly clamping the arc-shaped clamp 121 to the outer wall of the original bamboo stake 11, achieving circumferential constraint and fixation. The fastening bolt 122 can be selected with appropriate length and specifications according to the diameter of the bamboo joint 113 of the original bamboo stake 11. After tightening, it can provide sufficient clamping force, enhancing the fit and friction between the clamp and the original bamboo stake 11.

[0059] In one embodiment, the radius of the arc of the arc-shaped clamp 121 is smaller than the radius of the internode 112 of the original bamboo pile 11.

[0060] Specifically, the arc-shaped clamp 121 is attached to the internode 112 of the original bamboo pile 11, so that its inner wall applies a certain clamping force to the original bamboo pile 11 in the radial direction, thereby enhancing the fit and friction between the fastening mechanism 12 and the original bamboo pile 11.

[0061] Since there is a certain tolerance in the diameter of the internode 112 of the original bamboo pile body 11, and since the radius of the arc of the arc-shaped clamp 121 is slightly smaller than the radius of the internode 112 of the original bamboo pile body 11, there will be a certain flange gap when a pair of arc-shaped clamps 121 are fastened. This can accommodate bamboo joints 113 of different sizes and improve the adaptability of the fastening mechanism 12.

[0062] In one embodiment, the ground nail 142 is connected to a fastening mechanism 12 near the top of the original bamboo stake 11.

[0063] Specifically, the ground nail 142 is pre-driven into the stable soil layer of the slope's soil-filling area, forming a certain angle with the top of the original bamboo retaining pile 1, and traction is applied by diagonal tension. One end of the inclined cable 141 is fixedly connected to the ground nail 142, and the other end is connected to the fastening mechanism 12 installed at the top section 112 of the original bamboo pile 11, forming a stable triangular support structure.

[0064] In one embodiment, the ground nail 142 includes: a bearing plate 1421, an anchor plate 1422 and a central rib 1423. One end of the bearing plate 1421 and the anchor plate 1422 are connected, and the central rib 1423 is disposed on the anchor plate 1422 and connected to the bearing plate 1421.

[0065] Specifically, one end of the bearing plate 1421 and the anchor plate 1422 are connected to each other to form an L-shaped structure, which enhances the stress stability of the ground nail 142 in the soil; the cross section of the anchor plate 1422 is arc-shaped, and the central rib 1423 is set on the arc-shaped inner wall of the anchor plate 1422 and is integrally welded with the bearing plate 1421 and the anchor plate 1422.

[0066] The bearing plate 1421 is a horizontally positioned metal plate that forms surface contact with the surrounding soil after being driven into the ground. It primarily bears the tensile force transmitted from the original bamboo pile 11. Simultaneously, as the amount of soil piled on top of the bearing plate 1421 gradually increases, the ground nails 142 are further compacted and secured. The anchor plate 1422 is an inclined plate connected to the bearing plate 1421, inserted deep into the soil to provide good embedment depth and pull-out resistance. The central rib 1423 is longitudinally positioned along the central axis of the anchor plate 1422, enhancing the overall structural bending stiffness and dividing the soil into several blocks, thereby improving the torsional resistance of the ground nails 142 and providing stable support for the connection of the stay cables 141.

[0067] In one embodiment, the thickness of the anchor plate 1422 gradually decreases from one end near the bearing plate 1421 to the end away from the bearing plate 1421.

[0068] Specifically, the end of the anchor plate 1422 closest to the bearing plate 1421 has the maximum thickness to withstand the concentrated tensile force transmitted by the stay cable 141, while the end away from the bearing plate 1421 gradually thins out, and the end can transition into a pointed wedge or beveled structure, which helps to reduce resistance and increase the embedment depth of the ground nail 142 during the driving process into the soil, and increases the friction area and locking effect between the anchor plate 1422 and the soil.

[0069] The upper half of the central rib 1423 near the pressure plate 1421 has the same thickness, while the lower half away from the pressure plate 1421 has a gradually narrowing thickness.

[0070] In one embodiment, a connecting hole 1424 is provided on the central rib 1423, one end of the stay cable 141 is connected to the connecting hole 1424, and the other end is connected to the fastening mechanism 12.

[0071] Specifically, the connecting hole 1424 is opened in the middle area of ​​the upper half of the central rib 1423. The hole diameter is pre-designed according to the specifications of the cable 141 used to ensure that the cable 141 can be smoothly inserted and a firm connection can be achieved.

[0072] One end of the stay cable 141 passes through the connecting hole 1424 on the central rib 1423 and is fixed to the central rib 1423 by bolts, clasps or sleeves, etc. The other end of the stay cable 141 is connected to the arc-shaped clamp 121 on the original bamboo pile body 11 near the bearing plate 1421.

[0073] In one embodiment, the retaining plate 2 is a metal retaining plate 2.

[0074] Specifically, the retaining plate 2 is preferably made of galvanized steel plate or aluminum alloy material with good corrosion resistance, which can adapt to complex working conditions such as high humidity and strong acidity and alkalinity in mountainous environments.

[0075] The retaining plate 2 is rectangular in shape, with mounting holes at both ends to connect to the fastening mechanism 12 on the adjacent bamboo retaining pile 1. The retaining plate 2 is horizontally positioned between two adjacent bamboo retaining piles 1 and is fixed to the fastening mechanism 12 of each bamboo retaining pile 1 by fastening bolts 122 and nuts, forming a continuous retaining wall structure.

[0076] Installation method: Several arc-shaped clamps 121 are longitudinally installed on the outer wall of the original bamboo pile 11. One side of the top arc-shaped clamp 121 is fastened with bolts 122 and connected to the inclined cable 141. The nuts are tightened to press and fix the flange of the arc-shaped clamp 121. The tension rope 132 is passed through the small hole in the center of the bamboo membrane 111 from bottom to top through the original bamboo pile 11, with the top surface of the cone 133 pressing against the bottom bamboo node 113 of the original bamboo pile 11. The cover plate 1312 presses down on the top bamboo node 113 of the original bamboo pile 11. The top cover plate 1312 of the original bamboo pile 11 is hammered to drive the original bamboo pile 11 into the soil to a predetermined depth. Pre-tension is applied to the tension rope 132 through the cable locking device 1311 and fixed, pressing the cover plate 1312 tightly. Ground nails 142 are driven obliquely into the soil on the side of the pile, and one end of the inclined cable 141 is tied and fixed to the connecting hole 1424 of the central rib 1423. As the amount of soil piled up increases, the pressure on the bearing plate 1421 increases, increasing the anchoring stability of the ground nails 142. Retaining plates 2 are installed between two adjacent original bamboo piles 11. The two ends of the retaining plates 2 are fixedly connected to the fastening mechanism 12 on the original bamboo piles 11 by fastening bolts 122, completing the enclosure or linear structure layout of the retaining wall. The above steps are repeated according to the construction length to construct the entire retaining wall segment by segment.

[0077] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
