Abstract
Description
Technical Field
[0001] This utility model relates to the field of water conservancy ecological facilities technology, specifically, to an ecological reinforcement structure for deeply buried adjacent dangerous walls. Background Technology
[0002] In urban water conservancy projects, the surrounding environment is often relatively complex. There are often situations where the surrounding strata are unevenly distributed, the foundation is highly sensitive to settlement, and the surrounding underground pipelines are complex. However, due to local geological and ecological reasons, the vegetation cover on high slopes is poor. In cases of strong winds, rain, and wild animals, gravel rolling often occurs. The falling gravel poses a great safety hazard to road traffic. Due to the limitations of terrain and geological conditions, it is impossible to fully protect the surrounding slopes.
[0003] Currently, the main approach to addressing highway protection issues on steep slopes is through on-site inspections, regular maintenance, and the erection of safety warning signs or the installation of active and passive protective nets at key locations. However, this approach presents challenges due to the difficulty of conducting inspections and cleaning the active and passive protective nets.
[0004] For the reasons mentioned above, it is necessary to reinforce such dangerous walls at the edges. Those skilled in the art are seeking a reinforcement structure that is relatively low in cost and simple in construction. Utility Model Content
[0005] The purpose of this utility model is to address the shortcomings of existing technologies by providing an ecological reinforcement structure for deeply buried dangerous walls that offers good reinforcement effects, has a relatively simple structure, and has low modification costs.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is: an ecological reinforcement structure for deeply buried dangerous walls, including a buttress-type retaining wall, an ecological bag component, a concrete slope, a planting pipe, and a drainage ditch. The buttress retaining walls are evenly spaced on the upper part of the slope, and the bottom of the buttress retaining walls is continuously laid with a cast-in-place base plate. The ecological bag components are used to install the ecological bag components for planting plants between adjacent buttress retaining walls. The cast-in-place base slab is provided with a slope downwards from the wall base, and a concrete support layer is provided on the surface of the slope. The planting pipes are pre-embedded in the slope in a dispersed manner, and the planting pipes are used for planting plants; The drainage ditch is located at the lower edge of the slope and is used for drainage.
[0007] Preferably, the height of the buttress retaining wall is ≥1.5m.
[0008] Preferably, the buttress retaining wall has pre-embedded plant growth holes distributed in a plum blossom pattern.
[0009] Preferably, the ecological bag assembly includes a plurality of stacked ecological bags, the ecological bags being made of polypropylene, and the surface ecological bags being filled with alkaline soil or topsoil after removing impurities, in which fertilizer and plant seeds have been applied.
[0010] Preferably, the lower layer of the eco-bag is filled with sand and / or gravel.
[0011] Preferably, the concrete support layer is provided with plain shotcrete and wire mesh concrete sequentially from the bottom to the surface.
[0012] Preferably, the planting tubes are arranged in a quincunx pattern with a spacing of 0.4m*0.4m. The planting tubes are made of PVC pipe with a diameter ≥110mm and a length ≥10cm. The tubes are filled with planting soil, fertilizer and seeds.
[0013] Preferably, the slope ratio of the slope is 1:1.
[0014] Preferably, the bottom surface of the eco-bag is a sintered support end face.
[0015] Preferably, the plant is Bermuda grass.
[0016] This utility model has substantial features and advancements compared to existing technologies. Specifically, it sets up buttress-type retaining walls in the sections requiring protection, dividing the area to be reinforced into smaller segments. This ensures the stability of the reinforced structure, makes construction easier, and reduces costs. Simultaneously, ecological bags are installed within the intervals for planting vegetation, providing a green ecological effect. The lower slope is protected by a concrete support layer and planting pipes are added for planting vegetation, achieving the purpose of slope greening. A drainage ditch is set at the bottom to collect and drain slope water in a timely manner, preventing water accumulation from affecting safety. Through the protection of the above structure, it can effectively prevent the falling of gravel and rocks around the adjacent dangerous walls, protecting highway safety. Furthermore, due to the simple structure of the entire system, the construction difficulty is low, and the cost is relatively low. Attached Figure Description

[0020] The technical solution of this utility model will be further described in detail below through specific embodiments.
[0021] Taking the access road to the No. 3 Reservoir's underground water plant as an example, relevant experimental verifications were conducted. A section of the road near the Hong Kong and China Gas Company is above a wall originally built by Guangdong Water Resources Development Co., Ltd. Outside the wall are temporary prefabricated buildings belonging to Hong Kong and China Gas Company. The wall is approximately 43m long and 1.6m-2.5m high, with the road edge 3.5m from the wall. Part of the temporary prefabricated buildings of Hong Kong and China Gas Company are within the red line of the Shawan Interception and Drainage Project. The top of the wall has Hong Kong and China Gas Company's sewage pipes attached. The road under construction is 5m wide, with its outer edge 3.5m from the wall. The original terrain slope is 1:3 to 1:4, and the strata, from top to bottom, consist of miscellaneous fill, silty clay, and strongly weathered sand and gravel. The foundations of the wall and temporary prefabricated buildings are situated on a silty clay overburden layer.
[0022] The main difficulty in the construction of this project was that, during the on-site inspection, it was found that the dangerous wall had multiple horizontal or vertical cracks (crack width of about 5mm to 20mm), and the wall was already tilting outwards. The backfill soil inside the dangerous wall reached above the top of the wall, and the wall was tilting outwards due to the influence of soil pressure. The foundation of the prefabricated house used I-beams inserted into the soil, and the I-beam foundation was 0.3 to 0.5m away from the wall. Multiple cracks were found on the surface of the backfill soil. Other reinforcement methods would be difficult to achieve the final effect.
[0023] For the reasons mentioned above, this embodiment implements an ecological reinforcement structure for deeply buried adjacent dangerous walls, such as... Figure 1 and Figure 2 As shown, it includes a buttress retaining wall 1, an eco-bag component 2, a slope 4, a planting pipe 5, and a drainage ditch 6.
[0024] The buttress retaining walls 1 are evenly spaced on the upper part of the slope 4. The height of the buttress retaining walls is ≥1.5m. The bottom of the buttress retaining walls 1 is continuously laid with a cast-in-place base plate. The ecological bag components 2 are used to set between adjacent buttress retaining walls. The ecological bag components 2 are used to plant plants 3.
[0025] During construction, due to the presence of multiple horizontal or vertical cracks in the dangerous wall, and the wall already tilting outwards, the surrounding area was excavated and cleared before construction. After the foundation slab concrete was poured and reached the required strength, a lightweight buttress retaining wall 1 was constructed. The reinforced concrete buttress retaining wall was used to divide the section to be reinforced into smaller sections, and plant growth holes were pre-embedded in a quincunx pattern on the buttress retaining wall 1 to achieve the effect of blocking the lateral pressure transmitted from the dangerous wall.
[0026] The eco-bag assembly consists of several stacked eco-bags, supported by single-sided sintering using a non-woven needle-punching process on polypropylene material. The eco-bags are filled with alkaline soil or topsoil after removing weeds and other impurities. The bottom three layers of eco-bags are filled with sand and gravel in a soil:gravel ratio of 7:3, mixed with mushroom fertilizer to promote vegetation growth at a rate of 3 kg / m³. 3 Spraying Bermuda grass seeds at a density of 30g / m² into the soil 3 .
[0027] The planting of grass involves sowing grass seeds on the completed eco-bags and using the nutrient soil inside the eco-bags to provide nutrients for the grass. At the same time, the eco-bags have water absorption and retention effects, allowing the plants to grow effectively.
[0028] The cast-in-place base slab is provided with a slope 4 along the wall base downwards. The slope ratio of the slope is 1:1. A concrete support layer is provided on the surface of the slope 4. In specific construction, after the slope is repaired, 5cm of plain concrete is sprayed first, then a steel mesh is hung, and then 5cm of concrete is sprayed again after completion to achieve the effect of stabilizing the slope.
[0029] The planting pipes 5 are dispersed and pre-buried in the slope. The PVC planting pipes are arranged in a quincunx pattern with a spacing of 0.4m*0.4m on the slope. The planting pipes 5 are PVC pipes with a diameter of 110mm, with a horizontal and vertical spacing of 0.4m and a length of 10cm. They are staggered vertically. The original soil is dug 15cm deep at the bottom of the planting pipe. Planting soil is filled in the dug area and the area of the planting pipe. Firecracker flower seeds are sown in the planting soil, 0.5g per hole.
[0030] Once completed and the vegetation has grown, the project achieves both slope stabilization and a green ecological effect, while also utilizing rainwater and improving soil quality. The buttress retaining wall and its ecological design effectively reinforce the soil. It demonstrates advanced and superior features in terms of construction safety, progress, and economy, and has significant potential for wider application in similar projects.
[0031] Finally, it should be noted that: the preferred embodiments of this patent have been described in detail above, but this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
