Description

Technical Field

[0001] The present application belongs to the technical field of tunnel construction and is applied to the construction of tunnel slope retaining walls. It specifically relates to a tunnel ecological slope structure that integrates environmental protection, landscaping, support, and overall forming construction. Background Art

[0002] Traditional tunnel slope protection is divided into civil engineering retaining wall protection and environmentally friendly landscape plant protection. Retaining wall protection alone only addresses the safety concerns of tunnel entrance and exit slopes, which damage the original soil and rock formations, but fails to consider the comprehensive construction of the slope. Greening the slope alone only addresses the initial vegetation restoration and landscape fragmentation issues of the project, but fails to consider the sustainability of the slope ecosystem. Only by integrating civil engineering structures, environmental protection, and landscape design, and integrating multiple construction methods, can a multifunctional slope structure be achieved. Utility Model Content

[0003] The purpose of this application is to provide a tunnel ecological slope structure to solve the problem that a single slope construction cannot comprehensively manage the tunnel slope.

[0004] The purpose of this application is achieved through the following technical solutions:

The extension portion is tied and connected to the trough structural steel bars of the upper-level planting trough, and the extension portion is cast in the concrete of the upper-level planting trough.

[0013] Furthermore, the anchor rod includes an anchor rod reinforcement and a grouting body in the anchor hole. The anchor rod reinforcement is located in the grouting body, and the outer end of the anchor rod reinforcement is connected to the planting groove.

[0026] The present application will be further described below with reference to specific embodiments and accompanying drawings.

[0027] refer to Figures 1 to 3 As shown, a tunnel ecological slope structure includes a tunnel slope 1, a foundation 2, a planting trough 3, an anchor rod 4, soil and vegetation 5, and a surface drainage ditch 6.

[0028] The tunnel slope 1 is a side slope and / or an upslope, that is, the slope structure can be constructed on the side slope, on the upslope, or on both the side slope and the upslope at the same time, and can be flexibly selected according to the actual situation on site.

[0029] Regardless of the side slope or the back slope, the tunnel slope 1 is at least one of the slopes on one side, both sides and the upper side of the tunnel entrance. That is, according to the actual situation on site, it can be applied to multiple locations, and the working location can be flexibly selected to ensure structural safety from multiple angles while having a good greening and aesthetic effect.

[0030] The tunnel slope 1 is equipped with several planting troughs 3 arranged in a stepped pattern along the slope. These troughs contain soil and vegetation 5, forming a supporting structure for the surrounding slope. They also serve as a container for greenery, achieving a slope structure that integrates environmental protection, landscape, support, and safety. The planting troughs 3 not only retain soil and protect the slope, but also provide greenery and plant life. They also store water, eliminating the need for frequent watering and maintenance. They can also serve as backup drainage ditches when the intercepting ditch at the top of the slope is overloaded.

[0031] The planting trough 3 is connected to the anchor rod 4, and the anchor rod 4 is anchored on the tunnel slope 1. The anchoring effect of the anchor rod 4 is utilized to improve the fixing effect of the planting trough 3 on the slope, thereby ensuring the stability and reliability of the overall structure.

[0032] Foundation 2 supports the lowest level of planting troughs 3, which in turn support the next level. This step-by-step support structure reduces the need for support personnel and scaffolding materials, resulting in a lightweight, stepped ecological slope with low requirements for foundations and subgrades, allowing for unlimited stacking heights depending on conditions. Foundation 2 is located at the bottom of the tunnel slope 1. It is an enlarged structure larger than the planar outline of the planting troughs 3 to increase bearing capacity and transmit downward pressure from above.

[0033] The planting trough 3 is a reinforced concrete structure, and the cross-section of the planting trough 3 is a right-angled trapezoidal structure. The right-angled side of the right-angled trapezoidal structure faces the tunnel slope 1, that is, inward, and the long bottom of the right-angled trapezoid is the upper groove opening. For the planting trough 3 supported by the upper and lower steps, the lower bottom of the upper-level planting trough just acts on the upper bottom of the lower-level planting trough, and the upper bottom of the upper-level planting trough does not block the upper groove opening of the lower-level planting trough, does not affect the planting function, and has better stability.

[0034] The planting trough 3 consists of concrete and trough reinforcement 301. One end of the trough reinforcement 301, facing the tunnel slope 1 (the right-angled side of the right-angled trapezoidal structure), has an extension 302 extending out of the concrete. This extension 302 is tied and connected to the trough reinforcement 301 of the previous planting trough 3 and cast within the concrete of the previous planting trough 3. The reinforced concrete connection between the upper and lower planting troughs 3 improves overall stability.

[0035] The anchor rod 4 includes an anchor bar 401 and a grouting material within the anchor hole. The anchor bar 401 is located within the grouting material, and the anchoring of the anchor bar 401 to the tunnel slope 1 improves the stability of the planting trough 3. The outer end of the anchor bar 401 is provided with a bent portion 402, which is tied and connected to the trough structure steel bar 301 of the planting trough 3. The bent portion 402 is cast in the concrete of the planting trough 3 to achieve a reliable connection between the anchor bar 401 and the planting trough 3.

[0036] The ground drainage ditch 6 is used to store and drain the accumulated water on the ground.

[0037] The workflow of this application:

[0038] 1. According to the particularity of linear engineering, the scope of the slope is determined in combination with the construction drawings and construction plan, and then the surface is cleared and subsequent danger removal work is carried out.

[0039] 2. Based on the geological conditions of the slope in the geological survey report, calculate the anchor length and steel bar size, make a plane layout, use an anchor drill to drill holes in the slope, place anchor steel bars and reserve steel bar joints (bends), then pour cement mortar and tie it to the anchor steel bars to form a whole.

[0040] 3. Pour plain concrete at the foot of the slope to expand the foundation to increase the bearing capacity and the downward pressure transmitted from above.

[0041] 4. Tie and connect the trough structure reinforcement and the anchoring reinforcement, and reserve a first-level planting trough insert (extension part) in the upright section of the trough structure reinforcement (the right-angled side of the right-angle trapezoidal structure). Close the mold and pour concrete. When the strength reaches 100%, the planting trough at this level can be used as a construction platform to construct the next-level planting trough. Repeat the construction until the top of the slope.

[0042] 5. Select vegetation based on environmental protection and landscape design and plant it in planting troughs to form an ecological protection slope.

[0043] The aforementioned basic examples and their further selected examples can be freely combined to form multiple embodiments, all of which are embodiments that can be adopted and claimed for protection in this application. In this application, each selected example can be arbitrarily combined with any other basic examples and selected examples.

[0044] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
