Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of hydraulic engineering, and particularly relates to a protection structure design for a reservoir slope, and is especially an innovative solution for improving the stability of a reservoir slope and meeting the demand for rapid construction. BACKGROUND

[0002] Traditional reservoir slope protection is mostly achieved by means of concrete walls, gabion nets or natural vegetation, but these methods have problems such as long construction period, high cost, difficult maintenance or limited protection effect. In particular, under extreme weather conditions such as heavy rain and earthquakes, traditional protection structures are easily damaged, affecting the safety of the reservoir. Therefore, it is particularly important to develop a new protection structure that can be quickly installed and effectively enhance the stability of the slope.

[0003] Among them, the patent file CN201921167390.6 a kind of green protection structure of reservoir slope, the patent proposes a kind of green protection structure of reservoir slope, including slope body, protection net, frame, sliding rod, stop lever, fixed seat, baffle, hanging rod, backboard, side plate and front plate etc. Among them, the slope body is provided with protection net on the inclined surface, and the frame is arranged in the slope body, the upper and lower sides of the frame are provided with through holes, the sliding rod is slidably connected to the left side of the frame, and the stop lever is rotatably connected to the right side of the sliding rod by a rotating shaft. The fixed seat is fixedly connected to the left end of the sliding rod, the baffle is rotatably connected to the front and rear sides of the fixed seat, the hanging rod is fixedly connected to the backboard, and the backboard is connected with the side plate and the front plate to form a space for planting landscape plants. The technical scheme enables the device to be retracted into the frame when not in use, facilitating transportation. When in use, the stop lever can be extended through the through holes, increasing the contact area with the slope and improving the stability of the device. At the same time, the backboard and the front plate are provided with landscape plants, which beautify the environment and enhance the protection effect of the slope.

[0004] But there is the shortcoming of inconvenient assembly:

[0005] The protection structure of the patent is composed of multiple components, and the assembly process is relatively complex. In particular, the connection and cooperation between the sliding rod, stop lever, fixed seat, baffle and other components require high precision, and a large amount of adjustment and calibration work may be required during assembly. In addition, due to the large number of components, it is easy to miss or incorrectly install during assembly, affecting the stability and protection effect of the overall structure.

[0006] And there is a potential problem of insufficient strength:

[0007] Although the protective structure of this patent takes stability and protection effect into account in design, in actual application, if material selection is improper or construction process is not rigorous, it may lead to insufficient strength of the overall structure. Especially the key components such as frame body, sliding rod and stop rod, if the material strength is not enough or the connection is not firm, damage may occur under extreme load or deformation, thereby affecting the overall performance and safety of the protective structure.

DETAILED DESCRIPTION

[0029] The present application will be further described in detail below with reference to the accompanying drawings, so that those skilled in the art can implement it according to the description.

[0030] It should be noted that the experimental methods described in the following embodiments are conventional methods, and the reagents and materials, unless otherwise specified, can be obtained from commercial channels; in the description of the present application, the orientation or positional relationship indicated by the terms is based on the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element must have a particular orientation, be constructed and operated in a particular orientation, therefore it cannot be understood as a limitation on the present application.

[0031] like Figs. 1-6 As shown, this utility model provides a reservoir slope protection structure, including: a steel structure lattice beam 1 made of high-strength steel, wherein the lattice beam 1 is divided into standard sections 11 and connecting sections 12. The standard sections 11 have a uniform length, and the connecting sections 12 are equipped with a quick-locking mechanism for quick connection between the lattice beams 1. The cross-section of the lattice beam 1 is trapezoidal or rectangular, and the surface is coated with an anti-corrosion coating. Optionally, the steel is selected from Q235, Q345, and Q460 steel. Q235 steel is a common carbon structural steel with characteristics such as low price, good machinability, and excellent weldability. Preferably, the high-strength steel is selected from Q345 and Q460 steel, which have higher strength and toughness and can withstand greater loads and deformations.

[0032] In the above technical solution, the lattice beam 1 is made of high-strength steel, with a trapezoidal or rectangular cross-section to increase its resistance to bending and torsion. The beam surface is coated with an anti-corrosion layer to extend its service life. The lattice beam 1 is divided into standard sections 11 and connecting sections 12. Standard sections 11 have a uniform length, facilitating mass production and transportation; connecting sections 12 are designed with a quick-locking mechanism, eliminating the need for welding or extensive bolt connections, significantly reducing splicing time. This technical solution utilizes the quick-locking mechanism of connecting sections 12 to achieve rapid and accurate connections between lattice beams 1, greatly reducing on-site construction time.

[0033] Another technical solution also includes a soil anchoring system, in which each transverse lattice beam is fixed by anchor rods 2 pre-embedded in the slope soil, and the ends of the anchor rods 2 are connected to the lattice beams by special joints 3.

[0034] In the above technical solution, each transverse lattice beam is fixed by anchor rods 2 pre-embedded in the slope soil. The ends of the anchor rods 2 are connected to the lattice beams through special joints 3 to ensure structural stability.

[0035] In another technical solution, the lattice beams are stacked and installed at a preset inclination angle to form a multi-layered protection system.

[0036] In the above technical solution, the lattice beams are stacked at a certain angle to form a multi-layered protection system, effectively dispersing soil pressure and improving the overall stability of the slope. The combination of the multi-layered lattice beam structure and the soil anchoring system in this technical solution effectively enhances the slope's resistance to sliding and erosion.

[0037] The lattice beams are installed in a preset inclination, which means that each layer of lattice beams has a certain inclination angle relative to the previous layer. This stacking method not only increases the number of protective layers of the slope, but also makes the entire protection system more stable and three-dimensional. The preset inclination is determined according to the inclination angle of the slope, the characteristics of the soil, and the expected protection effect. Through reasonable inclination design, it can ensure that the lattice beams and the slope form a good fit, thereby more effectively resisting soil erosion and slope instability and other safety hazards. The lattice beams are connected to each other by anchor rods and other means to form a whole stable protection system. This connection method not only enhances the connection strength between the lattice beams, but also makes the entire protection system more coordinated and efficient.

[0038] In another technical solution, the quick locking mechanism is a thumb turn type lock 4.

[0039] The basic structure and working principle of the thumb turn type lock 4 are as follows:

[0040] 1. Knob: This is the directly operated part, designed in a shape that is easy to grip and rotate, usually circular or with a raised design for easy finger operation. The knob is fixedly connected with the internal threaded rod, and when the knob is rotated, it drives the threaded rod to move.

[0041] 2. Threaded rod: connected with the knob, with external threads that can cooperate with the internal threaded hole at the other end of the lock. When the knob is turned, the threaded rod will move axially under the action of the threads, thereby achieving locking or loosening.

[0042] 3. Locking washer: located at the end of the threaded rod, used to contact the surface of the fixed part. The locking washer usually has an anti-slip design to increase friction and ensure that it does not easily loosen in the locked state.

[0043] 4. Spring: an optional design, some designs may contain a spring that can provide additional reset force when loosening the lock, allowing the knob to automatically return to the initial position for the next operation.

[0044] 5. Guide mechanism: to ensure that the threaded rod moves stably along a straight line during rotation without deviation or jamming, the lock usually has a guide slot or guide sleeve structure inside.

[0045] 6. Housing: protects the internal components and provides an installation platform for users. The housing needs to have enough strength to withstand the pressure generated during locking.

[0046] In this technical solution, the quick locking mechanism is a thumb turn type lock 4, such as Figs. 2-4As shown, including the operating components (knob 41), with the operating components fixed connection connecting piece (rotary rod 42 and a pair of protrusions 43 provided on the side wall of the rotary rod 42), lock body 44 (fixedly installed on the side wall of the lattice beam design position), locking washer 45 (connecting plate, provided with two connecting holes, respectively for two rotary rods 42 to pass through, corresponding to the connecting hole, the side wall of the lattice beam is provided with a through hole with size and distance adaptation), the lock body 44 is provided with a radial groove 46, so that the rotary rod 42 rotates and drives the protrusion 43 to rotate into the groove 46 to realize clamping locking. The lock body 44 is provided with a guide hole 48 communicated with the groove 46, and the rotary rod 42 and the protrusion 43 can be inserted into the guide hole 48 at a certain angle. Among them, the anti-skid layer 47 can also be laid on the surface of the groove 46.

[0047] In another technical scheme, the upper and lower adjacent two vertical lattice beams are connected through the connecting plate and the quick locking mechanism.

[0048] In the above technical scheme, the quick locking mechanism is also a thumb turn type lock 4, as shown in Fig. 5 Among them, the connecting plate is provided in the form of a groove, and a channel steel can also be used. The connecting plate is clamped at both ends of the connecting section of the upper and lower adjacent two vertical lattice beams, and then locked and fixed by the thumb turn type lock 4.

[0049] In another technical scheme, the special joint 3 is provided with a connecting part matched with the connecting section, and a gap is sleeved on the exposed end of the anchor rod, and a concrete layer is formed by pouring concrete between the connecting part and the exposed end of the anchor rod.

[0050] In the above technical scheme, the specific steps of connecting the anchor rod, the lattice beam and the special joint 3 together generally include the following main links:

[0051] 1. Preparation work: First, the slope needs to be measured and laid out, the slope surface needs to be trimmed, and the rock slag, floating soil or dangerous rock on the slope surface and the slope bottom needs to be removed.

[0052] 2. Anchor hole construction: using a drilling machine to drill a slope anchor hole at the marked position on the slope.

[0053] 3. Planting anchor rod: planting anchor rod in the hole of slope anchor hole and pouring cement slurry. Before the anchor rod is put into the anchor hole, the quality and length of the anchor rod should be checked, and the length of the anchor rod should be consistent with the depth of the hole. When placing, the rod body should be prevented from bending and torsion, and the grouting pipe and the centering support or isolation frame should not be damaged.

[0054] 4. Hoisting lattice beam unit: excavating the lattice beam unit groove, and leveling the bottom surface of the groove. Hoisting makes the connecting sections of the adjacent two horizontal lattice beams butt joint, and the anchor holes on the connecting sections are sleeved on the corresponding anchor rods.

[0055] 5. Anchor rod and lattice beam connection: anchor rod is anchored into the lattice beam with a length of 40d, and the flange plate is installed to the connecting section of the two transverse lattice beams, a cylinder is provided on the center hole of the flange plate, the cylinder is sleeved around the anchor rod at intervals, and grouting is performed in the cylinder.

[0056] 6. Tensioning and locking: tensioning and locking the anchor rod. The tensioning equipment should be calibrated before tensioning; the compressive strength of the grouting body and the lattice beam concrete should not be less than 80% of the design strength.

[0057] 7. Anchor head treatment: grouting material is poured into each cylinder through the pre-buried grouting pipe, to the surface of the lattice beam, covering the top of the anchor plate. The anchor rod located on the upper part of the anchor pad is locked with a nut, and the concrete protective cover is filled and sealed at the anchor pad, anchor rod and nut.

[0058] 8. Acceptance test: perform anchor rod acceptance test, the maximum test load is 1.5 times the design axial uplift capacity of the anchor rod.

[0059] 9. Anchor sealing: after the anchor cable is tensioned and locked, the outer anchor head should be sealed and treated, and the thickness of the concrete protecting the anchor head should not be less than 5 cm.

[0060] These steps need to be strictly followed according to the construction technical specification and design requirements to ensure the stability and safety of the structure.

[0061] In this technical solution, as shown in Fig. 6 The special joint 3 includes a flange plate 31 and a cylinder 32 arranged on the flange plate 31. The flange plate 31 is flange-connected and fixed with the connecting section, and the cylinder 32 is fixed with the anchor rod through the concrete layer 33. The special joint 3 can be customized according to different anchor rods and lattice beam sizes to adapt to various complex slope environments and protection needs. Using the special joint 3 can simplify the construction process, improve the construction efficiency, and reduce the construction cost. Through the special joint 3 and the reliable connection mode, a firm combination can be formed between the anchor rod and the lattice beam, ensuring the stability and safety of the entire protection system.

[0062] Example 1:

[0063] High-strength steel material is selected as the lattice beam material, the cross section is designed as a trapezoidal shape, each standard section has a length of 3 meters, and the connecting section is designed with a quick locking mechanical fastener.

[0064] Grooves are excavated on the slope surface at a predetermined angle, anchor rods are implanted and grouted to solidify.

[0065] The lattice beams are installed in multiple layers, the standard section and the connecting section are connected by using the quick locking mechanism, ensuring that each layer of lattice beam is tightly fitted, and the anchor rod is fixed through the special joint 3.

[0066] After all lattice girder installation is completed, whether the connecting part is firm is checked, and the necessary adjustment and reinforcement are carried out.

[0067] (Actual situation can be adjusted specific parameter, such as lattice girder size, anchor rod length and spacing etc., to meet different slope protection needs.)

[0068] Although the embodiments of the present application have been disclosed as above, it is not limited to the application listed in the specification and the embodiments, and it can be fully applied to various fields suitable for the present application. For those skilled in the art, other modifications can be easily realized, and therefore the present application is not limited to specific details and the figures shown and described herein.
