Pneumatic Serial Device for Deep Soil Material Injection

The device segments the soil treatment process into multiple depth zones using a telescopic probe that can be extended to different depths. The probe is divided into segments that can be independently positioned at target depths, allowing the system to address both shallow and deep soil layers effectively, thereby resolving the contradiction between operation efficiency and application depth range.

The invention transitions from two-dimensional surface treatment to three-dimensional deep soil treatment by introducing vertical depth as a new dimension. The telescopic probe enables material application at various depths (0-30 meters), adding the depth dimension to the traditional surface-level spraying approach, thus expanding the application range while maintaining operational efficiency.

The device replaces traditional mechanical mixing methods (hoes, plows, excavators) with a pneumatic spraying system. Compressed air is used to inject materials directly into the soil at the target depth, eliminating the need for mechanical digging and mixing operations. This substitution reduces labor intensity while achieving uniform material distribution through controlled pneumatic injection rather than forceful mechanical mixing.

The invention employs pneumatic principles to deliver materials to the soil. Compressed air flows through the telescopic probe and injects materials directly into the soil matrix at the desired depth. This pneumatic delivery system eliminates the need for manual or mechanical mixing, reducing labor intensity while achieving uniform distribution through the natural diffusion and dispersion of materials carried by the air stream.

The device merges multiple functions into a single integrated system. The telescopic probe combines the functions of hole drilling, material delivery, and mixing into one operation. The pneumatic system simultaneously performs material injection and soil disturbance, eliminating the need for separate drilling and injection steps. This merging of operations reduces process complexity and accelerates the treatment cycle while maintaining deep soil treatment capability.

The telescopic probe is pre-assembled and positioned at the target depth before material injection begins. The probe structure is prepared in advance with the appropriate depth configuration, allowing immediate material delivery without the need for on-site hole drilling during the treatment process. This preliminary preparation simplifies the overall process and reduces the time required for deep soil treatment.

The pneumatic system uses dynamic pressure adjustment rather than constant high pressure. The compressed air pressure is regulated to match the specific depth and soil conditions being treated, using less energy for shallow applications and increasing pressure only when necessary for deep penetration. This dynamic pressure control reduces overall air consumption and energy use while maintaining effective material delivery to deep soil layers.

The system changes the pneumatic parameters (pressure, flow rate) based on the target depth and soil conditions. For deeper soil treatment, higher pressure and flow rates are used, while shallower applications use lower parameters. This parameter adjustment optimizes energy consumption by applying sufficient force only when and where needed, rather than using high pressure throughout all operations, thus reducing overall air pressure consumption while achieving the required penetration depth.
