BVEM Full Range of Vibroflotation Equipment System

BVEM has established a full range of vibroflotation equipment system, providing comprehensive solutions for various engineering projects and once again expanding the application scope of vibroflotation technology.

1. Dual Engines for Land Scenarios

· Excavator-integrated type: The vibroflotation main machine is deeply integrated with the excavator chassis. Utilizing the crawler mobility and precise operation advantages of the excavator, it realizes "stop-and-construct immediately". It is suitable for "space-constrained projects" such as urban old community reconstruction and mountain photovoltaic pile foundations, with a minimum construction radius that can be reduced to within 5 meters.

· Crane-suspended type: Relying on the lifting capacity of crawler cranes and truck cranes, it expands the vibroflotation depth (up to 71.63 meters) and pile diameter (maximum 1.5 meters). Equipped with a multi-connected vibroflotation module (the "multi-pile simultaneous vibration" equipment in the figure), it increases the construction efficiency by 200%, focusing on "large-scale pile foundation projects" such as ports, wharves, and high-speed railway hubs.

2. Breakthrough in Marine Scenarios: "Offshore Vibroflotation Plant" Adapted to Barges

For marine engineering such as offshore structures, artificial island soft foundation treatment, and submarine tunnels, BVEM has built a "vibroflotation equipment-barge integration system" to break through the barriers of the marine environment:

· Carrier revolution: A self-propelled barge (or modified engineering ship) is used as a mobile platform. The vibroflotation equipment is rigidly connected to the barge deck through intelligent guide rails, and is equipped with an active wave compensation system. It can sense the hull swing angle in real-time (≤3° sea condition) and automatically adjust the attitude of the vibroflotation device, ensuring that the pile verticality deviation is ≤1% of the pile length, thus solving the problem of "precision construction under wave interference".

· Anti-corrosion black technology: The vibroflotation device adopts a "titanium alloy shell + ceramic sealing coating", with an annual corrosion rate of ≤0.01mm in a marine salt spray environment. The hydraulic system has a built-in seawater filtration and circulation module, which directly extracts seawater for cooling, reducing freshwater consumption by 80% and adapting to long-term offshore operations.

· Deep diving expansion: Equipped with an underwater vibroflotation robot (ROV collaboration), it can achieve construction at a water depth of 60 meters through armored cables. The vibroflotation device has built-in pressure and vibration dual sensors, which can transmit stratum compactness and pore water pressure data in real-time, supporting onshore remote control of the "vibration energy - filling speed" curve, and filling the technical gap in "deep-sea soft soil foundation treatment".

· Formation operation: Barges, material transport ships, and positioning ships form an "intelligent construction formation":

· The material transport ship accurately supplies materials to the vibroflotation equipment through a laser-aligned "automatic hopper" (weight error ≤5%).

· The positioning ship uses DGPS satellite positioning + underwater acoustic positioning for dual protection, controlling the pile position deviation within ±10cm.

· Multi-ship collaboration shortens the single pile construction cycle to 4 hours (traditional technology takes 8 hours), increasing efficiency by 100%.

3. Special Customized Type

For extremely soft soil (bearing capacity <50kPa) and high-salinity strata, "anti-corrosion vibroflotation devices" and "ultra-high pressure flushing systems" have been developed; for extreme environments such as polar regions and plateaus, "low-temperature endurance power packs" and "plateau pressurization modules" have been designed to break through natural condition restrictions.

Technical Core: From "Experience-based Construction" to "Intelligent Regulation"

Behind each piece of equipment is an integrated "perception - decision - execution" intelligent system:

· Stratum self-adaptation: The vibroflotation device has built-in pressure and vibration frequency dual sensors, which can identify stratum compactness in real-time (such as relative density of sand, void ratio of clay), and automatically adjust the "vibration energy - filling speed" matching curve to achieve "one-click adaptation" to complex strata.

· Construction visualization: Construction parameters (pile depth, compactness, filling amount) are superimposed through AR technology, allowing managers to monitor remotely. Abnormal data automatically triggers an early warning (such as immediate shutdown when pile deflection >1.5°), reducing the construction error rate to within 0.3%.

· Energy efficiency optimization: The "variable frequency motor + servo hydraulic" system is adopted, reducing energy consumption by 40% compared with traditional equipment; noise control technology enables the equipment to have a daytime noise ≤75dB and nighttime noise ≤55dB when constructing in residential areas, breaking through environmental protection restrictions.

From the "blossoming" of equipment forms to the "precision drip irrigation" of technical applications, BVEM takes "diversity" as the key to breaking the situation. It not only solves the practical problem of "how to choose vibroflotation equipment for different projects" but also promotes the upgrading of vibroflotation technology from a "foundation treatment method" to an "engineering system solution", providing a new paradigm for the "refined construction" of China's infrastructure.
