What it does
Sinking shaft TBMs with real-time geological monitoring probe strata between shifts.
Your inspiration
Amid rapid urban expansion, land scarcity and limited space hinder sustainable development. Underground space offers a solution, easing issues from two-dimensional expansion. However, existing excavation methods struggle in complex strata—often failing to control power during mixed-ground tunneling, causing collapses. Thus, a specialized TBM for complex geology is needed.
How it works
The sinking vertical shaft tunneling machine based on real-time monitoring technology for complex strata can utilize stratum detection technology during each work shift to assess the strata for the next excavation work. This ensures that the excavation work aligns with the corresponding strata conditions, avoiding scenarios such as excavation collapse and inefficient digging. It can effectively reduce the damage to the tunneling machine's cutter head caused by hard strata, enhance excavation efficiency, and also handle the challenges of excavating complex strata, thereby increasing the tunneling mileage of the sinking vertical shaft tunneling machine.
Design process
First, conduct research on the structure and technical support of the design goals. Analyze the internal and external structures of the sunk vertical shaft tunneling machine to ensure there are no conflicts during subsequent design work. Then, investigate real-time monitoring technology for complex strata, distinguishing between hardware and software components, and outline the workflow of the input processing end. Lastly, based on the workflow of the input processing end, propose improvements to the overall workflow to identify existing problems in the tunneling process and present ideas for design solutions, integrating feasibility and workflow insertion. Subsequently, analyze competing products in terms of numerical data and advantages, processing the researched parameter information in a more intuitive manner, thereby defining the product's design positioning and planning the subsequent design process in advance. Finally, based on the product's design positioning, carry out preliminary designs for aspects such as the product's VI (Visual Identity) and structure, refining and detailing all solutions, finalizing the product's main color scheme and other color options.
How it is different
The sinking vertical shaft tunneling machine can use real-time monitoring technology of complex strata to detect the geological hardness and distribution of the strata that will be encountered during the next excavation in advance. Based on the obtained results, it can control the excavation trajectory, rotation speed of the main tunneling unit, and replace the tunneling head to excavate the vertical shafts of different strata distributions and geological hardness. Compared to current tunneling machines, which primarily excel in shallow excavation and soft geological excavation, but have made little progress in deep excavation and complex strata, this technology can leverage strata monitoring combined with different tunneling heads and measures to reduce damage to the main unit when excavating hard strata.
Future plans
(1) The sinking vertical shaft tunneling machine, due to its large size, still has room for optimization in terms of installation and recovery, and innovations in process design can be made to address issues during the installation or transportation processes; (2) In terms of cross-section excavation, the sinking vertical shaft tunneling machine can optimize product structure for horizontal excavation radius and cross-section shape issues, to meet various excavation requirements for different cross-sectional structures.
