[0001] This invention relates to the field of tunnel boring machine (TBM) construction technology, specifically to a modular TBM launching reaction frame and its construction method. Background Technology

[0002] Currently, most underground tunnel projects use the shield tunneling method, which requires a shield launching reaction frame during the shield's initiation. The shield launching reaction frame is an integral part of the shield machine; its function is to support the launching end of the shield and transfer the initial reaction force to the foundation. Specifically, during the shield launching phase, the shield launching reaction frame applies a relatively opposite force to reduce the initial reaction force of the shield machine, preventing damage to buildings and underground pipelines inside or around the tunnel.

[0003] Existing shield tunneling machine (TBM) launching reaction frames have fixed dimensions, only suitable for specific TBM projects with fixed diameters, making reuse difficult. This not only increases construction costs and causes significant waste, but also makes storage and transportation challenging. Therefore, this application proposes a modular TBM launching reaction frame and its construction method, achieving scalability in frame dimensions, improving the applicability and reusability of the reaction frame, reducing construction costs, and facilitating storage and transportation, effectively solving the aforementioned problems.
