Underground Smart Parking System (Open-Caisson Technology)
The Underground Smart Shaft Parking System represents a revolutionary premium leap in urban sub-surface engineering. Designed as an invisible high-density car garage completely embedded below grade, it utilizes a sophisticated rectangular or circular vertical shaft layout. By keeping only sleek reception lobbies on the ground level and tucking the massive mechanical matrix entirely underground, this state-of-the-art system addresses critical city grid footprint limitations while preserving surface green spaces, urban parks, and architectural aesthetics.
1. Operating Principle: Multi-Axis Sub-Surface Logistics
The shaft system shifts the entirety of high-volume car storage to deep underground layers, functioning as a fully automated vertical elevator grid. The automated operation follows a synchronized mechanical sequence:
· Sleek Ground-Level Terminal Lobbies: Drivers easily enter and park their vehicles inside streamlined, modern reception terminals built cleanly on the surface plane. No underground ramp driving is ever required.
· High-Speed Vertical Shaft Transport: An intelligent robotic transporter takes absolute custody of the vehicle from the terminal. A centralized heavy-duty lifting platform lowers the car into a multi-tiered shaft, typically configured with 4 to 6 subterranean floors of high-density storage berths.
· Simultaneous 3-Axis Motion Routing: To minimize transit cycles and retrieve vehicles rapidly, the system coordinates three distinct movements simultaneously: rapid vertical lifting, precise lateral shifting, and smooth platform rotation. The vehicle is delivered to its allocated underground berth or brought up facing forward in a fluid, single-stroke wave.
2. Proprietary Civil Construction: Patented Sinking Well Innovation
What sets Dayang's underground system apart is our highly disruptive, proprietary civil engineering approach. Backed by more than 30 national patents (including 7 core invention patents), the foundation utilizes an advanced Prefabricated Assembly + Sinking Well (Open-Caisson) construction technique:
· Factory-Assembled Heavy Steel Shells: The massive shaft linings and structural steel shells are pre-engineered and completely assembled under strict quality control at our specialized factory production site.
· Simultaneous Extraction & Sinking: During site deployment, excavation and caisson sinking are executed at the exact same time. The structure sinks under its own controlled weight as soil is extracted from the core.
· Zero Slope Excavation & Multi-Decade Preservation: Unlike traditional construction, there is absolutely no need for wide slope cutbacks, expansive soil anchoring, or massive perimeter shoring walls around the foundation.
· Ultra-Short Construction Window with Zero Structural Impact: This specialized technique slashes the required civil construction window dramatically and creates virtually no settlement risk or vibrational impact to adjacent historical buildings, existing foundations, or buried municipal utilities.
3. Technical Mechanical Configurations
To ensure absolute durability down to the 6th underground tier, the system employs high-specification commercial-grade mechanical components:
Engineering Parameter | Mechanical System Specifications | Operational Benefit to Developer |
Drive Form Architecture | Heavy-duty Commercial Traction Drive System managed by precision variable-frequency inverters. | Delivers exceptionally high vertical transit speeds, smooth harmonic acceleration, and maximum energy savings. |
Vehicle Exchange Mechanisms | Customizable options: High-Speed Interlocking Comb-Tooth Systems OR Smart Robot Tire-Clamp Wheel Dollies. | Eliminates individual parking pallets, accelerates car swap sequences, and reduces down-shaft mechanical maintenance. |
Intelligent Orientation | Heavy-duty 180-degree integrated mechanical turntable within the lifting network. | Ensures vehicles are automatically turned underground so they emerge at the surface terminal facing forward, eliminating reversing. |
4. High-Value Strategic Applications
Because the system is invisible from the surface and causes zero damage to surrounding infrastructures during installation, it is specified by municipal engineers for:
· Urban Roads & Multi-Lane Boulevards: Built vertically beneath roadside greenbelts, sidewalks, or setbacks without disrupting heavy city traffic lines or requiring road closures.
· Public Parks, Plazas, & Civic Squares: Preserves precious surface landscape aesthetics, flora, and pedestrian recreation zones completely, hiding hundreds of cars directly beneath the turf.
· Tight Inter-Building Gaps & Historic Core Infills: Deploys safely inside tight courtyards or narrow passageways between existing structures where standard excavation or above-ground towers are completely illegal or physically impossible.
