Double Shield Tunnel Boring Machines (TBMs) Overview
Double shield tunnel boring machines (TBMs) are a critical component in the construction of large-scale underground tunnels. These machines are designed to excavate and support tunnel walls simultaneously, providing a continuous shield during the boring process. This method enhances safety and efficiency, particularly in urban environments where ground stability is crucial. The double shield TBM operates by employing two distinct shields: a primary shield that supports the excavation front and a secondary shield that protects the tunnel behind the cutterhead. This dual-shield system allows for the installation of tunnel linings and other structural supports as the machine advances. The ability to perform excavation and lining installation in one continuous operation minimizes disruption to the surrounding environment and infrastructure, making double shield TBMs highly suitable for complex urban and suburban projects.
Open Type Double Shield TBMs
The open type double shield tunnel boring machine is designed for use in soil and soft ground conditions. This type of TBM features an open shield design, allowing for efficient excavation in less stable ground conditions. The machine utilizes a series of segmented steel liners to support the tunnel face during the excavation process. The open type double shield TBM is well-suited for projects where soil stability is a concern, as it provides continuous support to the excavation face and reduces the risk of ground collapse. The open shield design also facilitates the use of various excavation tools, such as rotary cutters or grippers, to adapt to different soil types. This flexibility makes the open type double shield TBM a popular choice for urban tunneling projects, where varying ground conditions can pose significant challenges.
Closed Type Double Shield TBMs
Closed type double shield tunnel boring machines are engineered for use in more challenging ground conditions, including hard rock and mixed face conditions. The closed shield design offers enhanced protection for the excavation crew and equipment by enclosing the entire excavation area. This design minimizes the risk of ground collapse and protects against water inflow, which is particularly important in areas with high water tables. Closed type TBMs are equipped with advanced hydraulic and mechanical systems to manage the excavation process and support the tunnel face. These machines are often used in projects where ground conditions are highly variable or where significant ground support is required. The closed shield design ensures a stable and safe working environment, making it suitable for large-scale infrastructure projects in both urban and remote areas.
Combination Type Double Shield TBMs
Combination type double shield tunnel boring machines incorporate features from both open and closed shield designs, offering a versatile solution for a range of ground conditions. This type of TBM is equipped with an adaptable shield system that can be configured to suit different soil and rock conditions encountered during excavation. The combination design allows for the use of open shield features in softer ground and closed shield features in more challenging conditions. This flexibility enables the TBM to efficiently handle varying ground conditions without the need for extensive modifications. The combination type double shield TBM is particularly useful for projects that traverse through diverse geological formations or where the ground conditions are unpredictable. Its adaptable design ensures that the machine can maintain operational efficiency and safety throughout the tunneling process.
Segmental Lining Double Shield TBMs
Segmental lining double shield tunnel boring machines are specifically designed to install pre-cast concrete segments as the machine advances through the tunnel. This type of TBM features a lining system that enables the simultaneous excavation of the tunnel and the installation of structural linings. The segmental lining TBM is equipped with a segment erector that positions and secures the pre-cast segments in place, ensuring a precise and consistent tunnel lining. This method provides immediate structural support to the tunnel, reducing the risk of ground collapse and improving the overall stability of the excavation. Segmental lining double shield TBMs are commonly used in projects where rapid tunnel construction is required, and where the tunnel needs to be supported immediately to maintain safety and structural integrity. This type of TBM is particularly beneficial for urban tunneling projects where timely completion and minimal disruption are essential.
