Description

Technical Field

[0001] The present invention relates to the field of slope protection structures, and specifically to an ecological bamboo integrated slope protection structure and its construction method. Background Art

[0002] Traditional slope protection projects mostly use building materials such as steel and concrete, focusing on the safety of slopes, while often neglecting the attention to ecological functions. With the popularization of the concepts of environmental protection and sustainable development, how to restore the ecological functions of slopes while ensuring their safety has become a new design goal. Ecological slopes combine safety, ecology and landscape, and have become an important method for slope protection. Existing ecological slopes are mainly divided into plant type and plant-engineering composite type. Although plant roots can enhance the strength of soil masses, their reinforcement effect is mainly in the surface layer, and it will cause the reduction of the shear strength of shallow soil masses during rainfall, which is easy to cause local landslides. Therefore, there are certain limitations in single plant slope protection, and the combination of plant slope protection and engineering slope protection has become the current mainstream method. In addition, the support of the shallow surface layer of the slope protection is crucial for whether the slope protection can withstand soil landslides. The current support system is usually concrete, and concrete itself has a large impact on environmental pollution. The extensive use of concrete in slope protection goes against the concepts of environmental protection and high-quality development.

[0003] The prior art such as the construction method of an ecological integrated slope protection system with the Chinese publication number 202310303222.X: provides a construction method of an ecological integrated slope protection system, belonging to the field of civil engineering. The ecological integrated slope protection system is a "shallow plant root-deep composite anchor" integrated slope protection system. The integrated slope protection system includes: composite anchors, including bamboo anchors and bamboo strips connected to each other; the bamboo strips are connected between the bamboo anchors and form a spatial grid structure system with the bamboo anchors on the slope surface; an FRP reinforcement layer, which is wrapped around the vegetation section and the anchoring section of the bamboo anchor; an anchoring agent, including vegetation grouting material and ordinary grouting material; easily growing plants and roots, including herbaceous plants and shrub plants; plant nutrients, including growth hormones and water retention agents. The present invention can stabilize the slope, improve the safety performance of the slope, beautify the environment, be green and environmentally friendly, save energy and reduce emissions, and achieve the dual goals of ecological safety. The interaction between roots and soil can be used as a homogeneous anisotropic "composite soil mass", thereby improving the strength and surface stability of the slope soil layer.

[0004] However, in the prior art, during the protection process, the bamboo strips on the slope protection surface are extremely prone to corrosion, damage, and failure. Moreover, the bearing capacity of the bamboo strips is significantly smaller than that of the complete bamboo tubes. There are significant limitations in the conditions for using them as slope protection, and they are too monotonous as landscapes, resulting in a significant reduction in the flexibility of layout and being difficult to replace flexibly. The consideration of preventing soil landslides in this patent is inappropriate. Pure bamboo strips have obvious disadvantages in terms of anti-corrosion and mechanical properties. The application scenario in slope protection should be that there is no possibility of landslides in the soil slope itself. And during the drainage process, usually when water flows down from above the landslide, it is easy to cause soil erosion. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide an ecological bamboo integrated slope protection structure and its construction method to solve the technical problems of easy corrosion of the slope protection bamboo strips and inconvenient drainage of water.

[0006] To achieve the above object, the present invention provides the following technical solution: An ecological bamboo integrated slope protection structure includes a soil nail gasket and multiple groups of bamboo tubes. Gasket ears are connected to the periphery of the soil nail gasket. Double-layer steel sleeves are installed at both ends of the bamboo tubes. The double-layer steel sleeve is composed of a steel outer cylinder and a steel inner cylinder, and the bamboo tube is clamped between the steel outer cylinder and the steel inner cylinder. Opposing bolts are provided on the inner walls of the steel outer cylinder and the steel inner cylinder to fix and limit the bamboo tube. A nested steel ring is installed between the bamboo tube and the steel outer cylinder. Connection ears are connected to the ends of the double-layer steel sleeve, and prestressed holes are provided in the middle of the double-layer steel sleeve among multiple connection ears. The double-layer steel sleeve is fixedly connected to the gasket ear through the connection ear. FRP prestressed tendons are installed inside the bamboo tube, and both ends of the FRP prestressed tendons pass through the prestressed holes and extend to the outside of the bamboo tube. Prestressed tendon bases are connected to the outside of both ends of the bamboo tube located outside the double-layer steel sleeve. A drainage branch pipe is installed at the bottom end of the soil nail gasket and extends into the soil. A drainage main pipe is installed inside the soil, and the drainage branch pipe is fixed inside the drainage main pipe and extends into the interior of the drainage main pipe. Drainage grooves are provided on the outside of the drainage branch pipe and are connected to the drainage main pipe.

[0007] By adopting the above technical solution, it is convenient to build supports at different positions. During the building process, the double-layer cylinder sleeve is used to fix and limit the ends of the bamboo tubes, improving the stability of the support. And during the building process, the bamboo tubes can be fixed and limited by the soil nails and the drainage branch pipes, improving the installation effect.

[0008] The present invention is further provided that a locking collar is connected to the top end of the soil nail gasket, and the locking collar is sleeved on the outside of the soil nail and fixedly connected to the soil nail.

[0009] Preferably, it is convenient to fixedly connect the soil nail gasket and the soil nail, improving the stability.

[0010] The present invention is further configured such that the soil nail gasket is hexagonal, and six groups of gasket ears are installed on the outer side of the soil nail gasket. Corresponding to each group of soil nail gaskets on the outer side, six groups of bamboo tubes are connected, and the bamboo tubes are of a hexagonal structure.

[0011] Preferably, it is convenient to form a hexagonal support structure and improve stability.

[0012] The present invention is further configured such that the soil nail gasket is quadrilateral, and four groups of gasket ears are connected to the outer side of the soil nail gasket. Corresponding to each group of soil nail gaskets on the outer side, four groups of bamboo tubes are connected, and the bamboo tubes are of a quadrilateral structure.

[0013] Preferably, it is convenient to form a quadrilateral support structure and reduce the usage cost.

[0014] The present invention is further configured such that shear bars are correspondingly installed on the outer side of the connecting ears. After the shear bars are fitted with the gasket ears, the shear bars fix the shear bars and the gasket ears together.

[0015] Preferably, it is convenient to fix the double-layer steel sleeve to the soil nail gasket.

[0016] The present invention is further configured such that a prestressed tendon fastener is connected to the outer side of the prestressed tendon base. The prestressed tendon fastener is snap-fitted with the FRP prestressed tendon, and the prestressed tendon fastener limits the prestressed tendon base.

[0017] Preferably, it is convenient to support the bamboo tubes, thereby improving the strength of the bamboo tubes.

[0018] The present invention is further configured such that a bamboo strip vegetation grid is installed between the bamboo tubes. Fixing strips and strip bolts are connected to the outer wall of the bamboo tubes. The end of the bamboo strip vegetation grid is fitted to the outer side of the bamboo tubes. The fixing strips fix the end of the bamboo strip vegetation grid to the outer wall of the bamboo tubes, and the strip bolts fix and lock the fixing strips.

[0019] Preferably, it is convenient to plant vegetation in the soil between each group of bamboo tubes, and further reduce the effect of soil erosion.

[0020] The present invention is further configured such that a cover plate is inserted at the bottom end of the soil nail gasket. A water inlet is provided on the side surface of the cover plate, and a filter screen is provided on the outer wall of the water inlet. A rotating ring is sleeved on the outer side of the cover plate, and a plurality of scraping blades and fan blades are provided on the outer wall of the rotating ring.

[0021] Preferably, it can conveniently filter the incoming water, and drive the scraping blades to clean the impurities attached to the water inlet by rotating the rotating ring.

[0022] The present invention is further configured such that a support frame is connected inside the drain branch pipe, a fixing ring is connected to the top end of the support frame, a support ring is connected to the bottom end of the support frame, and a plurality of fixing rivets are installed on the outer side of the support ring. The support frame is fixedly connected to the cover plate through the fixing rivets, and the support frame is located on the side of the drain trough.

[0023] Preferably, it is convenient to fix and limit the drain branch pipe, and at the same time limit and guide the soil nails.

[0024] A construction method for an ecological bamboo integrated slope protection structure includes the following steps:

[0025] Step 1: Connect the double-layer steel sleeve with the bamboo pipe. The circular hole between the outer steel cylinder and the inner steel cylinder is closed at one end and open at the other end. There are prestressed holes at the closed part of the inner steel cylinder to facilitate the passing of the FRP prestressed tendon. Insert the wall of the bamboo pipe between the outer steel cylinder and the inner steel cylinder of the double-layer steel sleeve device, drill holes in the double-layer steel sleeve device to form through holes in the bamboo pipe, then insert the tension bolts and tighten them, and the tension bolts do not pass through the axis of the bamboo pipe.

[0026] Step 2: Squeeze the bonding glue between the bamboo pipe and the outer steel cylinder, and then insert the nested steel ring into the possible gaps between the bamboo pipe and the outer steel cylinder. After the double-layer steel sleeves are installed at both ends of the bamboo pipe, insert the FRP prestressed tendon into the bamboo pipe, and clamp one end of it with the prestressed base at this end of the double-layer steel sleeve.

[0027] Step 3: Apply a prestressing force to the other end to form a prestress with the double-layer steel sleeves at both ends of the bamboo pipe, and tighten the FRP prestressed tendon to form a complete component.

[0028] Step 4: Install the main drain pipe into the slope, then insert each drain branch pipe into the main drain pipe, and connect the connecting ears and gasket ears of each component reliably through the shear bars to form the entire assembled bamboo slope protection system. Install bamboo strip vegetation grids between each bamboo slope protection, and then plant in the grids.

[0029] Step 5: Insert bamboo pipes around each soil nail gasket at an angle perpendicular to the slope surface to form a circle, and firmly tie the bamboo pipes near the double-layer steel sleeve with the fixing strip and strip bolts. Then, snap the bottom end of the soil nail gasket onto the cover plate.

[0030] Step 6: Then pass the soil nail through the soil nail gasket, insert the soil nail into the drain branch pipe, and the bottom end of the soil nail passes through the support frame and inserts into the lower soil. The support frame initially fixes the soil nail, and then the soil nail continues to be inserted into the soil to further limit the soil nail. Rotate the soil nail gasket to fix it at the top end of the drain branch pipe, and then lock the soil nail through the locking collar.

[0031] In summary, the present invention mainly has the following beneficial effects:

[0032] 1. Through the soil nail gasket and the double-layer steel sleeve provided in the present invention, the end of the bamboo tube can be preliminarily fixed. Subsequently, through the gasket ears around the soil nail gasket, it is clamped and fixed with the FRP prestressed tendons connected to the double-layer steel sleeve. According to requirements, multiple groups of bamboo tubes are formed into the required shape to protect the slope. After the slope protection is assembled, the soil nail gasket is limited by the drain branch pipe and the soil nail, thereby further fixing the slope protection. And when replacing the bamboo tube, it can be disassembled by disassembling the double-layer steel sleeve, and the disassembly is relatively convenient.

[0033] 2. The present invention also passes through the drain branch pipe and the drain main pipe provided. During rainy weather, the water at the top of the slope can be discharged through the drain main pipe. The water on the slope will enter the drain branch pipe through the water inlet on the side of the cover plate and enter the drain main pipe through the drain groove on the side of the drain branch pipe, thereby also discharging the rainwater on the slope and improving the drainage efficiency.

[0055] Please refer to Figures 8 to 13 , a drain branch pipe 10 is installed at the bottom end of the soil nail gasket 1. The drain branch pipe 10 extends into the soil. A drain main pipe 11 is installed inside the soil. A shielding cover plate 1101 is connected to the top port of the drain main pipe 11. The shielding cover plate 1101 shields large and small impurities from the outside. The drain branch pipe 10 is fixed inside the drain main pipe 11 and the drain branch pipe 10 extends into the drain main pipe 11. Drainage grooves 1001 are provided on the outer side of the drain branch pipe 10 and are connected to the drain main pipe 11. A cover plate 12 is inserted at the bottom end of the soil nail gasket 1. A water inlet 1201 is provided on the side of the cover plate 12. A filter screen is provided on the outer wall of the water inlet 1201. A rotating ring 1202 is sleeved on the outside of the cover plate 12. Multiple scraping blades 1203 and fan blades 1204 are provided on the outer wall of the rotating ring 1202, which can facilitate the discharge of water flow and reduce the accumulation of water flow on the slope.

[0056] In the above embodiment, specifically, please refer to Figure 9 , a locking collar 102 is connected to the top end of the soil nail gasket 1. The locking collar 102 is sleeved on the outside of the soil nail 9, and the locking collar 102 is fixedly connected to the soil nail 9.

[0057] In the above embodiment, specifically, please refer to Figures 5 to 7, a bamboo strip vegetation grid 7 is installed between bamboo tubes 8.

[0058] In the above embodiment, specifically, please refer to Figure 11 and Figure 13 , a support frame 13 is connected inside the drainage branch pipe 10. The top end of the support frame 13 is connected with a fixing ring 1301, the bottom end of the support frame 13 is connected with a support ring 1302, and a plurality of fixing rivets 1303 are installed on the outside of the support ring 1302. The support frame 13 is fixedly connected with the cover plate 12 through the fixing rivets 1303. The support frame 13 is located on the side of the drainage groove 1001.

[0059] The second embodiment:

[0060] Please refer to Figures 14 to 15 , which is the second embodiment of the present application. The specific difference is the soil nail gasket 1. The soil nail gasket 1 is quadrilateral, and four groups of gasket ears 101 are connected to the outside of the soil nail gasket 1. Four groups of bamboo tubes 8 are connected to the outside of each soil nail gasket 1, and the bamboo tubes 8 are of a quadrilateral structure, which is convenient for building supports on slopes in different environments.

[0061] When the present invention is installed, first, the double-layer steel sleeve 2 is connected to the bamboo tube 8. One section of the circular hole between the steel outer cylinder 201 and the steel inner cylinder 202 is closed and the other section is open. There is a prestressed hole 206 at the closed part of the steel inner cylinder 202 to facilitate the passing of the FRP prestressed tendon 3. The wall of the bamboo tube 8 is inserted between the steel outer cylinder 201 and the steel inner cylinder 202 of the double-layer steel sleeve 2. Drilling holes are made in the double-layer steel sleeve 2 device to form through holes for the bamboo tube 8, and then the tie bolts 203 are inserted and tightened. The tie bolts 203 do not pass through the axis of the bamboo tube 8 to facilitate the passing of the FRP prestressed tendon 3. Then, bonding glue is squeezed into the space between the bamboo tube 8 and the steel outer cylinder 201, and then the nested steel ring 204 is inserted into the possible gaps between the bamboo tube 8 and the steel outer cylinder 201. After the double-layer steel sleeves 2 are installed at both ends of the bamboo tube 8, the FRP prestressed tendon 3 is passed through the bamboo tube 8. One end of it is clamped with the double-layer steel sleeve 2 at this end through the prestressed base 4, and a pre-tension is applied to the other end so that the double-layer steel sleeves 2 at both ends of the bamboo tube 8 together form prestress, and the FRP prestressed tendon 3 is tightened to form a complete component.

[0062] Then, according to the needs of each group, the drainage main pipe 11 is first installed inside the slope, and then the drainage branch pipes 10 of each group are plugged into the drainage main pipe 11 to realize the assembly. The connecting ears 205 and the gasket ears 101 are reliably connected through the shear rods 207 to form the entire assembled bamboo slope protection system. Bamboo strip vegetation grids 7 are installed between each bamboo slope protection, and vegetation is planted in the grids. Bamboo tubes 8 are inserted around each soil nail gasket 1 at an angle perpendicular to the slope surface to form a circle, and the bamboo tubes 8 are firmly tied to the double with fixing strips 5 and strip bolts 6. The soil nail 9 is inserted into the drainage branch pipe 10, and the bottom end of the soil nail 9 is inserted into the soil below through the support frame 13. The support frame 13 preliminarily fixes the soil nail 9, and then the soil nail 9 continues to be inserted downward into the soil, thereby further limiting the soil nail 9. The soil nail gasket 1 is then rotated to fix the soil nail gasket 1 on the top of the drainage branch pipe 10, and then the soil nail 9 is locked by the locking ring 102 to achieve the limitation of the soil nail gasket 1.

[0063] When it rains, the water flow at the top of the slope will enter the drainage main pipe 11 through the shielding cover 1101 and be discharged through the drainage main pipe 11. Some of the water flowing downward along the slope will first encounter the cover 12 and enter the interior of the drainage branch pipe 10 through the water inlet 1201. The drainage branch pipe 10 flows into the interior of the drainage main pipe 11 through the drainage groove 1001 on the side to discharge the water flow. During use, the water flow will continuously impact the fan blades 1204, driving the rotating ring 1202 to rotate. The rotating ring 1202 drives the scraper 1203 to clean impurities attached to the surface of the water inlet 1201, thereby improving the water inlet effect.

Then insert the tension bolts and tighten them, and the tension bolts do not pass through the axis of the bamboo tube. Step 2: Squeeze bonding glue between the bamboo tube and the outer steel cylinder. Then insert a nested steel ring into the possible gap between the bamboo tube and the outer steel cylinder. After the double-layer steel sleeves are installed at both ends of the bamboo tube, insert the FRP prestressed tendon into the bamboo tube and clamp one end of it with the prestressed base at this end. Step 3: Apply a pre-tension force to the other end to form a prestress with the double-layer steel sleeves at both ends of the bamboo tube, and tighten the FRP prestressed tendon to form a complete component. Step 4: Install the main drain pipe into the slope. Then insert each group of drain branch pipes into the main drain pipe. Connect the connecting ears and gasket ears of each component reliably through shear bars to form the entire assembled bamboo slope protection system. Install the bamboo strip vegetation grid between each bamboo slope protection, and then plant in the grid. Step 5: Insert bamboo tubes around each soil nail gasket at an angle perpendicular to the slope surface to form a circle, and firmly tie the bamboo tubes to the vicinity of the double-layer steel sleeve with fixing strips and strip bolts. Then snap the bottom end of the soil nail gasket onto the cover plate. Step 6: Subsequently, pass the soil nail through the soil nail gasket, insert the soil nail into the drainage branch pipe, and the bottom end of the soil nail passes through the support frame and is inserted into the underlying soil. The support frame initially fixes the soil nail, and then the soil nail continues to be inserted downward into the soil to further limit the soil nail. Rotate the soil nail gasket and fix the soil nail gasket at the top of the drainage branch pipe, and then lock the soil nail through the locking collar.
