Abstract: A fabricated rapid construction platform for a bridge, wherein the construction platform comprises a fixing frame, an upper-layer tubular pile position control structure (6), a lower-layer tubular pile position control structure (7), and a console; the fixing frame comprises a bottom rail platform (1), supporting posts (3), a top operation platform (2), and several supporting legs (4); the upper-layer tubular pile position control structure (6) and the lower-layer tubular pile position control structure (7) are provided between the bottom rail platform (1) and the top operation platform (2); the upper-layer tubular pile position control structure (6) comprises two sub-structures arranged symmetrically about the central axis of a second through hole, and each sub-structure comprises a braking device (61), a vertical control arm (63), and a horizontal control arm (62).

Abstract: A drone-based insect sample-collection system is disclosed, comprising a drone, a flight-control module and a sample-collection module. The flight-control module comprises a communication unit to transmit or receive signal to/from a user and a control unit to control the route of flight and collection site for the drone. The sample-collection module comprises a container, a gate-controlling unit, a chemicals-releasing unit and an optical-sensing unit. The container is provided with a gate which is controlled by the gate-controlling unit. The chemicals-releasing unit releases one or multiple chemicals to attract insects into the container. The optical-sensing unit is provided in the container and generates different signal according to the sensed light intensity. As the amount of the insect inside the container increases to gradually block the light intensity that the optical-sensing unit could sense, the signal generated by the optical-sensing unit is varied and transmitted to the gate-controlling unit.
