Background Technique

[0002] Tunnel shield construction is a method of constructing tunnels in the ground using a shield machine. It is a mechanized construction method in which the shield machine is pushed forward in the ground, the soil is excavated by a cutting device in front of the excavation face, transported out of the tunnel by an earth removal machine, and jacked forward by jacks at the rear, and precast concrete segments are assembled to form the tunnel structure.

[0003] Shield tunneling technology is widely used in the construction of subway interval tunnels due to many advantages such as high safety, fast tunneling speed, and small soil disturbance. However, the underground construction environment is extremely complex. If there are adverse geological conditions such as building pile foundations, river flood control piles, sunken ships, underground pipelines, cavities, and underground rivers in front of the shield machine during tunneling, it will greatly affect the construction quality, safety, and progress of the tunnel. Therefore, if the geological conditions in front are detected in advance during the tunneling process of the shield machine and the geological data of the pre-penetrated strata for shield construction are accurately understood, not only can corresponding technical measures be formulated in advance according to the geological conditions in front, but also the efficiency of tunnel tunneling construction can be effectively improved.

[0004] However, the current real-time tunnel geological advanced detection technology for shield machines is relatively single, inconvenient to use in the closed space between the shield machine and the heading face, and the detection accuracy of the detection device is relatively low.
