▎ 摘　　要

NOVELTY - The device has a first hollow sleeve (3) provided with a first sensor (2). A second hollow sleeve (6) is provided with a second sensor (7). A third hollow sleeve (10) is provided with a third sensor (11). A fourth hollow sleeve (4) is provided with a fifth sensor (5). A fifth hollow sleeve (9) is provided with a sixth sensor (8). A sixth hollow sleeve (13) is provided with a fourth sensor (12). An outer side of the first hollow sleeve is welded with a fourth hollow sleeve (4) and a sixth hollow sleeve (13). A side of the second hollow sleeve is fixedly connected with the first slide rail (14). Another side of the second hollow sleeve is fixedly connected with the second slide rail (15). An end of the fifth sensor is slidingly connected with the first slide rail. An end of the sixth sensor is glidingly connected with the second slide rail. USE - Device for monitoring six-degree-of-freedom graphene tunnel tube sheet staggered cracks. ADVANTAGE - The device combines the angular displacement meter and the displacement meter, so that measurement convenience and rapidness can be improved. The blowing device can avoid flying of crushed stone by a cover cylinder when the crushed block gravel is blown off. The monitoring device monitors tunnel pipe sheet staggered crack six-degree of freedom through the second sensor, the third sensor and the first sensor to obtain displacement amount of a measured object space in three-dimensional direction through the fourth sensor. DETAILED DESCRIPTION - A side of the third hollow sleeve is fixedly connected with a third slide rail (16). An end of the fourth sensor is slidingly connected with the third slide rail. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of a Device for monitoring six-degree-of-freedom graphene tunnel tube sheet staggered cracks.
