Description

Technical Field

[0001] This invention belongs to the technical field of underground engineering camouflage and ecological restoration, specifically involving an integrated construction method for camouflage and ecological restoration of the entrance of a cave-type data center. Background Technology

[0002] With the rapid development of global information technology, all industries inevitably face massive amounts of computer data storage and high-frequency computation, leading to an exponential increase in demand for information and data computing power. This has driven the rapid development of data center infrastructure. Against this backdrop, the nation has formulated the "Eastern Data, Western Computing" strategy, aiming to optimize the layout of data centers by constructing a new integrated computing network system encompassing data centers, cloud computing, and big data. Compared to surface data center facilities, underground data centers, such as cavern clusters, offer significant advantages including high concealment, resistance to attacks, low sensitivity to temperature and humidity environments, interference resistance, low pollution, and low energy consumption, making them an important development direction for new computing infrastructure.

[0003] However, the construction of underground data centers in cavern clusters is still in its early exploratory stages both domestically and internationally. The number of similar projects completed in my country is extremely small, and related technologies, standards, specifications, and engineering experience are severely lacking. As key protection targets during wartime or special periods, the concealment of data centers is crucial. Existing camouflage and protection methods for cavern data center entrances have the following prominent problems: First, traditional camouflage methods are often limited to simple painting or single-vegetation coverage, failing to deeply integrate with the natural form, texture, and color of the surrounding mountains. This results in obvious artificial traces, a visually jarring effect, and easy exposure of the project's location, making it difficult to meet the high security and confidentiality requirements of data centers. Second, conventional entrance construction causes significant disturbance to the surrounding mountains, vegetation, and soil environment, and lacks systematic ecological restoration measures, leading to a disconnect between the project and the natural landscape. Ecological restoration is difficult and ineffective, contradicting the concept of green and sustainable development.

[0004] Therefore, there is an urgent need to develop an integrated construction method that can organically combine engineering camouflage with ecological restoration, ensure a controllable construction process, and achieve a final effect that is highly integrated with the natural environment, in order to solve the technical problems of easily exposed entrances and significant ecological disturbances in underground data centers. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide an integrated construction method for camouflage and ecological restoration of the entrance of a cave-type data center. This method solves the technical problems of poor camouflage effect of the entrance of existing caves, easy exposure of the project location, large disturbance to the ecological environment during construction and difficulty in restoration. It realizes the unity of entrance camouflage and ecological restoration, and improves the concealment, security and environmental friendliness of the data center.

[0006] This invention provides an integrated construction method for camouflage and ecological restoration of the entrance of a cave-type data center, employing the following technical solution: An integrated construction method for camouflage and ecological restoration of the entrance to a cave-type data center includes the following steps: S1.

S7. Installation of climbing netting and planting of vegetation: Install climbing netting and plant climbing plants on the oblique cut surface of the cave entrance; S8. Shaft canopy camouflage and site greening: A reinforced concrete canopy is installed at the shaft opening, and the exposed surface is sprayed with camouflage stone paint. The top of the canopy is covered with artificial turf and filled with quartz sand. The disturbed area is covered with soil and greened.

[0007] Preferably, the cave entrance adopts a bamboo-cutting cave door, and its tilt angle basically matches the natural slope of the surrounding mountains.

[0008] Preferably, in step S2, the foundation treatment specifically involves: hanging 10mm diameter threaded steel bars on the slope, laying a single-layer bidirectional steel mesh with a mesh spacing of 200mm, and embedding 50mm long, 36×36×3mm angle steels in a quincunx pattern every 1500mm into the foundation, with 10cm protruding from the concrete surface. The steel mesh and angle steels are welded together, and 100mm thick C20 concrete is sprayed onto the slope.

[0009] Preferably, in step S2, the skeleton construction specifically involves: welding 36×36×3mm hot-dip galvanized angle steel to embedded parts at 1500mm intervals to form the main frame supporting the keel; welding 6mm round steel bars to Φ10mm threaded steel bars to form a rough shape, and laying galvanized mesh with 6mm×6mm holes and 1mm wire diameter on the surface of the shape; welding 150×150×10mm hot-dip galvanized plates to the existing retaining wall with embedded parts at 1500mm horizontal and vertical intervals; if there are no embedded parts, inserting M16×180mm chemical bolts for fixation; welding Φ10mm threaded steel mesh with a spacing of 750mm to the upper part of the retaining wall according to design requirements to construct the steel skeleton.

[0010] Preferably, in step S3, the shaping of the artificial rock and the setting of the planting troughs specifically involve: using a cement mortar spraying machine to spray the mortar from top to bottom, and then manually applying the mortar evenly to the framework for shaping, with an average overall thickness of 50mm and a local shaping thickness of 100mm; the planting troughs are arranged at a density of 100m². 2 There are 3 to 4 artificial stone facades.

[0011] Preferably, the planting trough is filled with breathable substrate or improved soil to a depth of not less than 40cm, and the climbing plants planted include at least one of windmill jasmine, ivy, star jasmine, and Virginia creeper.

[0012] Preferably, in step S5, the coloring uses natural mineral pigments or non-toxic and environmentally friendly coatings, and simulates the color of natural stone by brushing, spraying or manual color mixing; the anti-aging protection treatment is to coat the colored artificial stone surface with waterproof paint or anti-ultraviolet coating.

[0013] Preferably, in step S7, the climbing net is installed as follows: a post-installed embedded steel plate is installed on the oblique section of the tunnel entrance, fixed to the reinforced concrete outer wall of the tunnel using chemical anchors, the tension anchor is welded to the steel plate, and rust and corrosion prevention treatment is applied. The net is symmetrically arranged with a spacing of 250mm, centered on the tunnel centerline; both ends are tied to the transverse main load-bearing steel strands, which are 1×7 standard type with a nominal diameter of 21.6mm. Climbing plants are covered on the steel strands, with a plant weight limit of 0.3kN / m. 2 .

[0014] As a preferred embodiment, in step S8, the canopy is a reinforced concrete structure, and its top surface is covered with green artificial turf that mimics vegetation, with quartz sand filling the turf; after the area around the shaft opening is covered with soil, at least one of the following plants is planted: Chinese tallow tree, bamboo, grass seeds, and winter jasmine.

[0015] Preferably, in steps S2 to S5, the artificial rock skeleton, layered spraying, and artificial details together constitute the artificial rock structure. This structure, together with the bamboo-cut cave entrance, climbing vine net, vertical well canopy, and surrounding greenery, forms an integrated camouflage and ecological restoration system.

[0016] The construction principle of this invention is as follows: (1) Principle of camouflage at the entrance: By combining steel frame with shotcrete, a basic frame with sufficient strength and stability is constructed at the entrance and shaft opening. Through layered spraying, artificial shaping, surface carving and coloring, the artificial structure is simulated as the texture, cracks, folds and color layers of natural rocks, so that the entrance and the surrounding mountains form an integrated natural form. At the same time, climbing nets are set on the sloping surface of the bamboo-cut entrance and climbing plants are planted. Camouflage stone paint is sprayed on the exposed concrete surface, so that the artificial landscaping and natural vegetation can be quickly integrated and seamlessly connected with the surrounding natural environment, thereby effectively enhancing the concealment of the entrance and meeting the high confidentiality requirements of the data center. The shaft opening is mainly greened by backfilling around it. After backfilling, the surface is planted with grass species or low shrubs with strong local adaptability, so that it can naturally transition with the surrounding vegetation and avoid abruptness. A reinforced concrete canopy structure is set above the shaft. Camouflage stone paint is sprayed on the exposed concrete surface. The canopy roof is covered with green artificial turf and filled with quartz sand, etc., to form a "roof garden" style concealment effect, which further enhances the sense of nature. The combined effect of these multiple camouflage methods allows the entire project entrance to seamlessly integrate with the natural environment, thereby effectively meeting the data center's requirements for high confidentiality and concealment.

[0017] (2) Ecological Restoration Principles: After the construction of the artificial rockery at the entrance of the cave and the structure of the shaft, ecological restoration of the structure and its surroundings is carried out through soil improvement, vegetation configuration, and soil and water conservation measures. On the one hand, planting troughs are reserved or opened during the construction of the artificial rockery. The troughs are filled with breathable substrate or improved soil and planted with local weather-resistant climbing plants (such as star jasmine, ivy, star jasmine, Virginia creeper, etc.) so that the plant roots can gradually attach to the surface of the artificial rockery structure and form a stable plant community. On the other hand, the construction disturbance areas around the entrance of the cave and the shaft are covered with soil and mixed with grass seeds or planted with local suitable shrubs (such as Chinese tallow tree, bamboo, winter jasmine, etc.) to restore the surface vegetation. In addition, the climbing plants on the climbing net, the artificial turf on the roof of the shaft canopy, and the surrounding greening together constitute a multi-layered ecological cover layer, which effectively reduces soil erosion and accelerates the self-recovery of the ecosystem. By organically combining soil improvement, vegetation configuration, and water and soil conservation measures, the engineering structure can not only perform its camouflage function but also become an integral part of the regional ecosystem, thus achieving the integration of camouflage and ecological restoration.

[0018] The beneficial effects of this invention are: (1) Enhance camouflage and security: This invention integrates multiple technical means such as bamboo-cut cave entrance design, artificial rock mountain simulation, camouflage real stone paint spraying, and climbing vine net greening to deeply integrate the exposed structure of the cave entrance and shaft opening with the surrounding mountain shape, color and vegetation, effectively eliminating the visual abruptness of artificial structure, making the project integrated with the natural environment, greatly reducing the risk of being identified and exposed, and greatly improving the security and confidentiality of the cave-type data center.

[0019] (2) Achieving ecological restoration and environmental integration: This invention sets up planting troughs on the plastic stone facade and plants climbing plants, sets up artificial turf "roof gardens" on the top of the vertical shaft canopy, and covers the disturbed area with soil for greening, thus constructing a near-natural ecological community. This can not only quickly restore the vegetation cover of the construction disturbance area, stabilize the slope, and reduce soil erosion, but also promote the transition of artificial structures to natural ecosystems, achieve harmonious coexistence between engineering and the environment, and conform to the concept of green and sustainable development.

[0020] (3) Improved engineering quality and durability: This invention adopts a multi-layered, stable framework system consisting of reinforced concrete foundation, angle steel keel, steel mesh, and galvanized mesh, ensuring the strength and stability of the artificial rockery structure. Anti-aging protective treatment enhances the durability of the artificial rock surface color, reducing the frequency and cost of later maintenance. The integrated construction process design ensures close connection between each process, avoiding process conflicts and repetitive work, which is conducive to the control of overall project quality.

[0021] (4) Reduced construction costs and improved construction efficiency: This invention reduces additional costs caused by repairs, rework, and subsequent ecological restoration by implementing "simulation modeling - structural framework - ecological restoration" in an integrated and simultaneous manner. The streamlined construction organization improves efficiency, shortens the construction period, and reduces project management costs. At the same time, the use of climbing plants and greening to replace some permanent decorative structures reduces raw material consumption.

[0022] (5) Wide range of applications: This invention has achieved deep technical integration of engineering camouflage and ecological restoration in the field of cave-type data centers, forming a set of operable, replicable and effective construction methods; this method is particularly suitable for concealed projects with high requirements for ecological and environmental protection, such as rocky mountains and karst landforms, and has a good demonstration effect and broad prospects for promotion and application. It can be extended to other similar tunnel, national defense projects, important underground facilities and other entrance concealment and ecological management projects. Attached Figure Description

[0023] For ease of explanation, the present invention will be described in detail below with reference to specific embodiments and accompanying drawings.

[0024] Figure 1 This is a construction flowchart of an embodiment of the present invention. Detailed Implementation

[0025] The following are specific embodiments of the present invention described in conjunction with the accompanying drawings, further illustrating the technical solutions of the present invention. However, the present invention is not limited to these embodiments. Specific details, such as particular configurations and components, are provided in the following description merely to aid in a comprehensive understanding of the embodiments of the present invention. Therefore, those skilled in the art should understand that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present invention. Furthermore, for clarity and brevity, descriptions of known functions and structures have been omitted.

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this invention can be combined with each other.

[0027] This embodiment provides an integrated construction method for camouflage and ecological restoration of the entrance of a cave-type data center. The construction process is as follows: Figure 1 As shown, the specific steps are as follows: I. Construction Preparation and Surveying and Setting Out Based on the design drawings, the construction area for the entrances, shafts, and arch walls of the cave-style data center was cleared on-site. A total station was used for measurement and positioning, and the construction area was laid out as a grid, serving as the basis for subsequent framework construction and shaping. All incoming materials and equipment, including reinforcing steel, angle steel, cement, sand, gravel, stone paint, environmentally friendly pigments, artificial turf, quartz sand, as well as shotcrete machines, air compressors, and welding machines, were inspected to ensure they met quality requirements. Before construction, all relevant personnel underwent detailed technical briefings and safety training, clarifying construction techniques, quality standards, and safety precautions.

[0028] II. Foundation treatment and framework construction of the opening 1. Foundation Treatment: Clear loose soil and rocks from the slope surface, and fill and compact the soil in layers according to design requirements. On the treated slope surface, install 10mm diameter threaded steel bars, followed by a single-layer bidirectional steel mesh with a mesh spacing of 200mm. Every 1500mm, embed 50mm long, 36×36×3mm angle steel pieces into the foundation using a quincunx pattern, ensuring the angle steel protrudes 10cm above the concrete surface. Weld the steel mesh and angle steel pieces together. Apply a 100mm thick layer of C20 concrete to the slope surface and cure it in layers to form a stable foundation layer.

[0029] 2. Skeleton Construction: (1) Hot-dip galvanized angle steel with a specification of 36×36×3mm is welded to the embedded parts to form the main frame of the keel support, with a spacing of 1500mm between the angle steels.

[0030] (2) A rough framework is formed by welding 6mm diameter round steel bars and 10mm diameter threaded steel bars to shape the basic form of the rockery. A galvanized mesh with a hole diameter of 6mm×6mm and a wire diameter of 1mm is laid on the rough framework surface and fixed with tie wire or welding to provide an adhesion base for subsequent mortar shaping.

[0031] (3) For the original retaining wall around the opening, if there are embedded parts, hot-dip galvanized steel plates with specifications of 150×150×10mm should be welded to the embedded parts, and the horizontal and vertical spacing should be controlled at 1500mm. If there are no embedded parts in the original retaining wall, four M16×180mm chemical anchors should be inserted for fixation. On the upper part of the retaining wall, Φ10mm threaded steel mesh with a spacing of 750mm should be welded according to the design requirements to form a stable and complete steel reinforcement frame.

[0032] III. Artificial Stone Shaping and Planting Trough Setup Cement mortar is prepared by mixing cement, sand, and water according to the designed mix ratio. After being thoroughly mixed, the mortar is sprayed onto the framework in layers from top to bottom using a spraying machine. Before the mortar initially sets, it is manually applied evenly to the framework to shape it, creating the base form of an imitation mountain rock. The average overall thickness of the sprayed mortar and manual shaping is controlled at 50mm, but for areas where a more prominent shape is needed, the thickness can reach 100mm.

[0033] To achieve ecological restoration and integration with nature, planting troughs are randomly set on the artificial stone facade, with a density of approximately 3 to 4 planting troughs per 100 square meters of artificial stone facade.

[0034] IV. Artificial Detail Modeling While the sculpting mortar layer has initially set but not yet fully hardened, use electric carving tools and hand carving tools to finely carve the mortar surface, simulating the texture, cracks, folds, and layers of natural rocks to create a natural effect of undulating peaks and valleys. After carving, the surface of the sculpted stone is carefully refined to enhance the simulation effect. Use a wire brush to clean surface impurities, making the texture more natural and smooth.

[0035] V. Surface finishing and coloring of artificial stone After the artificial stone structure has completely cured and dried, surface treatment is carried out. First, according to the design effect, natural mineral pigments or non-toxic and environmentally friendly coatings are selected and applied to the sculpted artificial stone surface using methods such as brushing, spraying, or hand-mixing. The colors simulate the hues of local natural stone, such as gray, brown, and cyan. For a more natural simulation effect, different colors can be sprayed with a spray gun to create a sense of layering; at the same time, tools such as wire brushes and sponges can be used to gently scrub away excess pigment and enhance the natural texture of the stone. After coloring, a layer of waterproof paint or UV-resistant coating is applied to the surface of the artificial stone for anti-aging protection to enhance its weather resistance and prevent color fading and surface aging.

[0036] VI. Spraying of real stone paint on the exposed surface of the opening Thoroughly clean and repair the exposed concrete surfaces of the tunnel entrance and internal arch walls, then apply a special primer. After the primer dries, spray in sections a camouflage paint that coordinates with the color of the external artificial rock formations. Spraying must be even to ensure that the color, thickness, and texture create a continuous and unified concealment effect with the external natural mountain and artificial rock formations.

[0037] VII. Installation of climbing netting and planting of vegetation 1. Climbing Net Installation: On the sloping surface of the bamboo-cut entrance, install post-installed embedded steel plates (300×300×20mm) at the designed locations, securing them to the reinforced concrete outer wall of the tunnel using four M20 chemical anchors. Securely weld the tensioning anchors to the steel plates and perform overall rust and corrosion protection treatment. Using the tunnel centerline as a reference, symmetrically arrange the embedded plates on both sides at 250mm intervals. Tie transverse main load-bearing steel strands at both ends of the embedded plates. The steel strands are 1×7 standard type, with a nominal diameter of 21.6mm (Type 1860). Finally, cover the steel strands with climbing plants, with a designed plant weight limit of 0.3kN / m².

[0038] 2. Planting: Fill the planting troughs set in step three with well-aerated substrate or improved soil to a depth of not less than 40cm. Select at least one climbing plant such as star jasmine, ivy, star jasmine, or Virginia creeper for planting.

[0039] VIII. Shaft Canopy Camouflage and Site Greening 1. Shaft Canopy Camouflage: The shaft opening is constructed with a reinforced concrete canopy. All exposed concrete surfaces of the canopy are sprayed with a camouflage stone paint that harmonizes with the surrounding environment, ensuring uniform color and texture.

[0040] 2. Greening on the roof of the canopy: Apply a special adhesive evenly to the roof surface of the canopy, then lay green artificial turf that resembles vegetation, and fill the turf with quartz sand to protect the turf and enhance its durability, creating a "roof garden" effect.

[0041] 3. Site greening: Cover the platforms, slopes and other areas disturbed during construction such as shaft excavation with soil, and plant at least one plant such as Chinese tallow tree, Chinese bamboo, grass seeds and winter jasmine according to the local climate and soil conditions to complete the site ecological restoration.

[0042] In addition, the key points for construction quality control in this embodiment are as follows: (1) Foundation and framework treatment Foundation compaction: The foundation compaction, shotcrete strength and thickness shall meet the design requirements, and curing shall be carried out for no less than 7 days.

[0043] Frame welding quality: The welds are full and smooth, without cracks, slag inclusions or other defects, and the spacing and dimensional deviations meet the specifications.

[0044] (2) Plastic stone spraying and artificial shaping Thickness control: The plastic stone spraying is applied in layers, with each layer generally 100mm thick, to ensure uniform spraying and prevent hollow areas or delamination.

[0045] Mortar mix proportion: Cement, sand, stone and other raw materials are mixed according to the mix proportion determined by the laboratory; mud content, slump and strength and other indicators are strictly tested.

[0046] Artificial shaping: Simulate the shape before the mortar initially sets. When carving details, pay attention to the texture, layering and stability, and avoid cracks, peeling and other phenomena.

[0047] (3) Surface finishing and coloring Coloring materials: Environmentally friendly and non-toxic pigments or coatings are selected, and the color tone is coordinated with the surrounding natural environment to ensure uniform and long-lasting surface color.

[0048] Anti-aging treatment: Spray a waterproof layer or UV-resistant coating, check the coating uniformity and check for defects such as missed areas or blistering.

[0049] (4) Planting of ecological vegetation Plant survival rate: Select weather-resistant climbing plants such as ivy, water and maintain them regularly, and observe and record them regularly.

[0050] (5) Existing model Decorative materials such as real stone paint and environmentally friendly coatings need to be tested with small samples. Large-scale construction can only proceed after the owner, designer, supervisor and other units confirm that the color, texture and design effect are consistent.

[0051] (6) Handling of non-conformities If insufficient thickness of the sprayed grout layer, loose framework, obvious defects in appearance, or uneven color are found, rework or local repairs should be carried out immediately until acceptance is passed. For serious quality problems, root cause analysis and responsibility allocation should be conducted, and corresponding rectification and handling should be carried out to prevent similar problems from recurring.
