Abstract: A ductile material, a method for manufacturing a ductile member, and an anti-collision device for bridge piers, wherein the ductile material includes specific components in parts by mass as follows: 50-62 parts of thermoplastic polyurethane, 11-33 parts of neodymium-iron-boron, 12-24 parts of nickel-titanium alloy, 2-3 parts of metal magnetic powder, and 1-2 parts of polypropylene or polyethylene or polylactic acid or polyetheretherketone. The use of the ductile material, the method for manufacturing a ductile member, and the anti-collision device for bridge piers facilitates navigation.

Abstract: A superhydrophobic self-luminous concrete material for 3D printing and a method for preparing the same, belonging to the field of building materials. The superhydrophobic self-luminous concrete includes: cement: 1000-1500 parts; quartz sand: 1000-1300 parts; silica fume: 50-100 parts; water: 300-400 parts; water reducing agent: 8-12 parts; cellulose ether: 1-2 parts; defoamer: 2-3 parts; fiber: 4-8 parts; luminous powder: 75-85 parts; reflective powder: 30-45 parts; metakaolin: 15-25 parts; metal filler: 0.015-0.040 parts; and a superhydrophobic coating. By combining 3D printing with the superhydrophobic self-luminous concrete material, the characteristics of energy saving, environment friendliness, high efficiency and low consumption of the 3D printing are highlighted, and the superhydrophobic self-luminous concrete material can be utilized to efficiently prepare fine and special-shaped components.

Abstract: A cable detection robot and a working method thereof, wherein the cable detection robot includes: a first main body, a second main body, and a rotatable mechanism. The first main body and the second main body each include a support, a driving apparatus, and a holding apparatus; the driving apparatus includes a first wheel and a driving motor, to drive the first wheel to move along a cable through the driving motor; the holding apparatus is symmetrically arranged on two sides of the support, each side includes a first servo motor, connecting to a supporting wheel group; the supporting wheel group is perpendicular to a surface of the cable, the holding apparatus holds or is separated from the cable through rotation of the first servo motor, and relative positions of the first main body and the second main body are adjusted through the rotatable mechanism to implement obstacle surmounting.
