。[Detailed description of the invention] [Industrial application field] Automatically measures the soil quality of the face, the presence of foreign objects, the state of collapse, etc. using electromagnetic waves to prevent mechanical or construction troubles and improve efficiency and rationality. This invention made it possible to carry out construction in a variety of ways.

壊にまで至る恐れがある。Construction management for shield excavation must always consider the condition of the excavated ground and manage it in a way that suits the ground. but,
Unlike the hand-dug shield construction method, the conventional mechanical sealed shield construction method has a structure in which the shield machine has a partition wall that prevents direct visual inspection of the ground. For this purpose, the ground investigation results and the discharged soil,
Due to the load of the shield machine, etc., it is necessary to carry out construction while assuming excavated ground. However, with this method, it is difficult to accurately grasp soil conditions such as changes in strata, the presence or absence of obstacles (driftwood, large gravel, buried objects, etc.), or construction conditions such as loosening of the face, over-drilling, and collapse. The current situation is that there are delays. This not only prevents smooth excavation, but in the worst case, it may lead to failure of the shield machine or collapse of the face.

によって問題点を解決しようとする発明である。It is not possible to accurately grasp soil conditions such as changes in strata, the presence of obstacles, or construction conditions such as loosening of the face, over-excavation, and collapse, which not only delays response and impedes smooth excavation, but in the worst case scenario. This may lead to failure of the shield machine or collapse of the face. In order to overcome these problems, this invention attempts to solve the problems by using a face detection device that uses an electromagnetic wave device and a particle size measuring device to more accurately know the condition of the ground during excavation. .

At the same time, the soil collected from the chamber is sent to a particle size measuring device, and the particle size signal obtained by the display device for the particle size measuring device is sent to the image processing device and data processing device to determine the soil quality of the face ground at the face. This problem was solved by capturing the differences in reflected electromagnetic waves due to differences, the occurrence of driftwood, boulders, etc., the creation of cavities due to collapse, etc., and supplementing the electromagnetic wave exploration results with particle size signals.

る。The transmitting/receiving antenna device attached to the cutter face of the sealed shield machine repeatedly sends and receives data to the face under the control of the display device, and this is due to differences in the soil quality of the face ground, the occurrence of driftwood, boulders, etc., the creation of cavities due to collapse, etc. The difference between the reflected electromagnetic waves is captured and this input signal is sent to a display device or image processing device for image processing and display. In addition, to determine the soil quality, the grain size signal obtained by passing the soil collected from the chamber through a grain size measuring device is sent to a display device, and the grain size signal processed by the display device is input to an image processing device to supplement the exploration results using electromagnetic waves. It is something to do. The above exploration data is displayed on the screen and recorded by the data processing device. The electromagnetic wave detection mechanism uses a display device and an image processing device to analyze electromagnetic waves emitted from a transmitting antenna of an antenna device and performs image processing to make a determination.
