Abstract: A distributed optical fiber monitoring system for failure monitoring of a deep rock mass is applied to an underground chamber and can simultaneously monitor failure signals in axial and radial directions of the underground chamber, facilitating three-dimensional positioning of a failure source. The distributed optical fiber monitoring system includes a first optical fiber and a second optical fiber. The first optical fiber is deployed on a chamber wall along the axial direction of the underground chamber to monitor the failure signal distributed along the axial direction of the underground chamber. The second optical fiber mainly includes a peripheral optical fiber segment and a direction-changing transition segment. The peripheral optical fiber segment is deployed on the chamber wall along a cross-sectional profile of the chamber wall to monitor the failure signal distributed along the radial direction of the underground chamber.

Abstract: Disclosed are a grouting pipe and a construction method of a desert water storage area. An isolation layer can be constructed in any desert area to form the water storage area. A plurality of anchoring claws are arranged between an inner pipe and an outer pipe of a pipe body. The anchoring claw has a grouting flow channel for grouting into surrounding sand grains. When the grouting pipe is being laid, the anchoring claw is folded. During grouting, an elastic bag structure supports the anchoring claw. The pipe body can be firmly anchored in the sand grains. Slurry sprayed out of the anchoring claw moves from the pipe body by a certain distance, with a wider flowing range in the sand grains, and can meet and condense with slurries of other drilled holes, which facilitates better formation of the isolation layer, so that the desert water storage area is formed.

Abstract: Disclosed are an automatic labeling machine and an automatic labeling machine control method. The automatic labeling machine is used for adhering an identification label on a surface of a test tube. The automatic labeling machine comprises: a tube insertion port (80) used for inserting a test tube; a controller (4) used for determining the type of test tube to be inserted; and a prompting apparatus (3) connected to the controller (4) and used for outputting prompting information corresponding to the type of the test tube to be inserted. The problem of automatic labeling machines easily causing a test tube selection error in the prior art is solved.
