TBM tunnel boring machine is an advanced underground tunnel construction equipment that can efficiently and safely excavate various types of strata, and is widely used in tunnel construction projects such as urban subways, railways, and highways.
The working principle of TBM tunnel boring machine is based on mechanical excavation and rock fragmentation technology. It mainly consists of a cutterhead, a propulsion system, a support system, and a control system. The cutterhead is the core component of TBM, equipped with multiple cutting tools for cutting and crushing rocks. After the TBM is started, the cutterhead will rotate at a certain speed, cutting the rock and transporting it outside the tunnel through a conveyor belt. At the same time, the propulsion system generates thrust through hydraulic cylinders to push the TBM forward. The support system reinforces and supports the tunnel wall in real-time during the TBM advance process to ensure construction safety. The control system is responsible for monitoring and controlling various parameters of the TBM to ensure its normal operation.
TBM tunnel boring machine has many advantages, such as fast construction speed, high quality, safety and reliability. Compared with traditional blasting methods, TBM can reduce the damage to the surrounding environment, and lower the impact of noise and vibration. In addition, TBM can also achieve automated control, improve construction efficiency and management level.

The Blue Ocean Intelligent Installation LDJ400 series multifunctional tunneling machine is a specialized equipment used for non explosive excavation of tunnels. It mainly utilizes the high-frequency hammer or breaking hammer of the working department to impact and break rocks, the wedge or drill rod to pry and break rocks in the surrounding rock, and the heavy force of the free face under the surrounding rock. The high-frequency hammer is mainly used for rocks below 40MPa; the breaking hammer is used for mining rocks with higher hardness and poor development. (). The local control of mining+remote control of mining line can adapt to the excavation of 6-9.5 ? tunnels, and integrate the functions of frequent rock breaking, soft ? fast excavation, contour trimming, spray dust removal, etc. into the ? body. It is suitable for the construction of restricted blasting sections (such as airports, residential areas and wild ? animal protection areas), with strong adaptability. It can be applied to various types of surrounding rocks, and reduce over excavation and collapse. and so on.
TBM tunnel boring machine is an advanced tunnel construction equipment with broad application prospects. In future tunnel construction projects, with the continuous advancement and innovation of technology, TBM will play a greater role in promoting the development of the tunnel construction industry.
