Fall dangerous place inquiry device of tunnel inner wall

摘要

(57) Abstract Topic Fall dangerous place of concrete of tunnel inner wallThe tunnel inner wall which can investigate rapidly efficientlyIt designates that the fall dangerous place inquiry device is offered as topic. SolutionsMicrowave sender 1 and this microwave sendingThe microwave which is generated with trust vessel 1 in tunnel inner wall 10 emissionIt reflects from transmission antenna section 2a and the tunnel inner wall 10 which it does,It is the reception antenna section 2b which receives microwave between specifiedEvery other locking, distribution facilities the sending and receiving antenna 2 which is done and aforementioned reception aThe receiver which the reflected wave which is received in ntena section 2b the reception is doneWith 3 and this receiver 3 the reception the reflected wave which is done image processingDoing, the computer 4 which has the display 4a which it displaysWith to consist of, from aforementioned transmission antenna section 2the tunnel inner wallEmits to 10 the microwave which, from tunnel inner wall 10 counterThe morphism abnormality of the reflected wave which is done, display of computer 4Fall of tunnel inner wall 10 it is dangerous by observing with 4a,As detected severe place, fall of the tunnel inner wall which is formed it is dangerousSevere place inquiry device.
