Description

A landslide-resistant highway slope reinforcement device Technical Field

[0001] This utility model relates to a landslide-resistant highway slope reinforcement device, belonging to the field of highway slope protection technology. Background Technology

[0002] With the large-scale construction of mountain expressways and riverside roadbeds, slope instability has become the primary geological problem threatening highway safety.

[0003] Traditional reinforcement structures include rigid, flexible, and composite structures. Rigid reinforcement structures, such as gravity retaining walls and prestressed cable-stayed frames, offer high load-bearing capacity and durability, but suffer from high construction and maintenance costs, long construction periods, poor geological adaptability, and severe ecological damage. Flexible reinforcement structures, such as geogrid-reinforced structures and three-dimensional vegetation nets, offer good terrain adaptability and eco-friendliness, but have limited load-bearing capacity, poor long-term durability, and are difficult to control in terms of quality. Composite reinforcement structures achieve a better balance between stability, economy, and ecology, but require meticulous design and strict construction control.

[0004] Therefore, designing a stable, economical, ecologically sound, modular, and easily controllable anti-landslide highway slope reinforcement device is an urgent technical problem to be solved. Summary of the Invention

[0005] Therefore, the purpose of this utility model is to provide a landslide-resistant highway slope reinforcement device that can overcome the shortcomings of the prior art.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] A landslide-resistant highway slope reinforcement device includes several prefabricated spliced ​​slope protection components installed on the slope. Multiple through holes are provided on the side of the prefabricated slope protection components, so that adjacent prefabricated slope protection components are connected to each other through connectors inserted into the through holes to form an integral slope protection structure. A first anti-slide pile is provided at the top of the slope, and a base is fixed to the toe of the slope through a second anti-slide pile. The top of the integral slope protection structure is connected to the first anti-slide pile through the extension of the connector, and the bottom is snapped to the base.

[0008] Furthermore, the precast slope protection component is a precast concrete slope protection component. The precast concrete slope protection component has matching protrusions and grooves on opposite sides, so that adjacent precast slope protection components are snap-fit ​​connected, and connectors are inserted into the through holes to splice each precast slope protection component into an integral slope protection structure.

[0009] Furthermore, planting grooves are provided in the middle of the prefabricated slope protection component.

[0010] Furthermore, the connector is a flexible connector.

[0011] Furthermore, the first anti-slide pile and the second anti-slide pile are wooden / stone piles or reinforced concrete piles.

The inclined surface of the T-shaped structure on the side closest to the precast slope protection component is perpendicular to the precast slope protection component, and the inclined surface is provided with a slot that is adapted to the precast slope protection component. The bottom of the precast slope protection component is connected to the base by the slot.

[0013] Furthermore, the base is an integral structure or a structure spliced ​​together from several base units.

[0014] Furthermore, it also includes several anchors that pass through the prefabricated slope protection components and penetrate deep into the slope body.

[0015] Furthermore, multiple anchoring holes are provided on the opposite side edges of the prefabricated slope protection component, and the anchors pass through the anchoring holes to anchor the prefabricated slope protection component to the slope body.

[0016] Furthermore, the anchor is a grouting anchor or a prestressed anchor.

[0018] This utility model features a simple structure and convenient, efficient construction. It connects several prefabricated slope protection components via connectors and anchors to form an integral slope protection structure with good adaptability and stability. Furthermore, this integral slope protection structure, through the combined action of the top anti-slide piles and the base at the slope toe, exhibits good load-bearing capacity and long-term durability. Construction quality is easily controlled, resulting in excellent anti-slide slope protection. In addition, planting vegetation within the prefabricated slope protection components not only provides excellent eco-friendliness but also further enhances slope stability.

[0024] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be understood that the preferred embodiments are for illustrative purposes only and are not intended to limit the scope of protection of the present invention.

[0025] Example 1

[0026] As shown in Figures 1 and 2, a landslide-resistant highway slope reinforcement device includes several prefabricated revetment components 1 installed on the slope. Multiple through holes are provided on the side of the prefabricated revetment components 1, so that adjacent prefabricated revetment components 1 are connected to each other through connectors 2 inserted into the through holes to form an integral revetment structure. A first anti-slide pile 3 is provided at the top of the slope, and a base 5 is fixedly connected to the toe of the slope through a second anti-slide pile 4. The top of the integral revetment structure is connected to the first anti-slide pile 3 through the extension of the connector 2, and the bottom is snapped to the base 5.

[0027] The precast slope protection component 1 is a precast concrete slope protection component, which can be a plain concrete precast component or a reinforced concrete precast component. Matching protrusions 101 and grooves 102 are provided on opposite sides of the precast concrete slope protection component, allowing adjacent precast slope protection components 1 to be snap-fitted together. Connectors 2 are inserted into through holes to splice the precast slope protection components 1 into an integral slope protection structure. The snap-fit ​​connection between adjacent precast slope protection components 1, and their interconnection via connectors 2, not only makes assembly and disassembly convenient and efficient but also ensures good overall structural stability.

[0028] Planting slots 103 are provided in the middle of the prefabricated slope protection component 1, which can not only plant green plants to ensure good ecological conditions, but also are lightweight and easy to operate and install.

[0029] The connector 2 is a flexible connector. The flexible connector can be a stainless steel chain, steel wire rope, or hybrid material rope, etc.

[0030] The first anti-slide pile 3 and the second anti-slide pile 4 can be wooden / stone piles, reinforced concrete piles, etc. Wooden / stone piles can be used for temporary projects or highway slope reinforcement for small landslides, while reinforced concrete piles have good bending resistance and can be used for highway slope reinforcement for medium and large landslides.

[0031] The base 5 is a precast concrete base, which can be a plain concrete precast base or a reinforced concrete precast base. The precast concrete base has a T-shaped structure that is narrower at the top and wider at the bottom. The inclined surface of the T-shaped structure near the precast slope protection component 1 is perpendicular to the precast slope protection component 1, and the inclined surface is provided with a slot 501 that is adapted to the precast slope protection component 1. The bottom of the precast slope protection component 1 is connected to the base 5 by the slot 501.

[0032] The base 5 can be a monolithic structure or a structure composed of several base units. The monolithic structure can be used for highway slope reinforcement in the case of small landslides; the base unit splicing structure can be used for highway slope reinforcement in the case of medium and large landslides.

[0033] Example 2

[0034] As shown in Figures 1 and 2, based on Embodiment 1, this embodiment provides a landslide-resistant highway slope reinforcement device, which also includes several anchors 6 that pass through the prefabricated slope protection component 1 and penetrate into the slope body.

[0035] Multiple anchoring holes are provided on the opposite side edges of the precast slope protection component 1. The anchors 6 pass through the anchoring holes to anchor the precast slope protection component 1 to the slope body. Adjacent precast slope protection components are snap-fitted together and connected to each other by connectors 2. At the same time, the anchors 6 are added to anchor them to the slope body, making the overall structure more stable.

[0036] The anchor 6 can be a grouting anchor, a prestressed anchor, etc. Grouting anchors can be used for the reinforcement of highway slopes with relatively stable rock strata, while prestressed anchors can be used for the reinforcement of highway slopes with large and medium-sized landslides or unstable rock strata.

[0037] The construction process for this device is as follows:

[0038] (1) Slope trimming and layout: clean up loose soil and loose rocks on the slope to ensure that the slope is flat. Layout the anti-slide piles and anchor holes at the design intervals on the top, toe and body of the slope, and mark the installation position of the prefabricated slope protection component 1.

[0039] (2) Drilling: The diameter of the anchor bolt hole is 10-20 mm larger than the diameter of the anchor bolt. The hole depth needs to penetrate the potential slip surface and enter the stable stratum. The hole inclination angle is perpendicular to the slope or slightly inclined downwards at 5°-10° to facilitate grouting.

[0040] (3) Install anchor bolts, insert anchor bolts after cleaning the hole, and cure for at least 24 hours after grouting;

[0041] (4) Install the prefabricated slope protection component 1, fit the prefabricated slope protection component 1 into the exposed part of the anchor rod, connect the adjacent prefabricated slope protection components 1 with snaps, and connect them to each other through flexible connectors. At the same time, the flexible connectors near the top of the slope are reserved with an extension section.

[0042] (5) Install base 5 at the toe of the slope. The slot 501 of base 5 is engaged with the bottom of the bottom prefabricated slope protection component 1. Use the second anti-slide pile 4 to fix base 5 at the toe of the slope.

[0043] (6) Construct the first anti-slide pile 3 at the top of the slope, and connect the reserved extension section of the flexible connector to the first anti-slide pile 3;

[0044] (7) Plant green plants inside the prefabricated slope protection component 1.

[0045] The above description is merely a preferred embodiment of the present utility model and is not intended to restrict the present utility model in any way. Any simple modifications, equivalent changes, and alterations made to the above embodiments without departing from the technical solution of the present utility model and based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
