The utility model relates to an auxiliary tool for collecting sticky eggs in a spawning pond, which is combined with the prior art, does not need to use the impact of water flow and other tools, and is characterized in that two to four workers are arranged in the spawning pond side by side from the outer edge of the spawning pond four hours after spawning of parent fishes, respectively hold a large shovel and move forwards along one direction by inclining 45 degrees along the bottom of the spawning pond; meanwhile, pushed water flow drives the fertilized eggs to drift to a concealed pipe in the middle of the spawning pond and flow into an egg collecting box along with fall, the head of the large shovel is smooth and fine, the bottom of the spawning pond is polished by a terrazzo, the fertilized eggs cannot be damaged, and the whole operation is convenient and fast, time-saving, labor-saving and water-saving.

This invention discloses a dismantling device and method for the substructure of a bridge, belonging to the technical field of bridge dismantling equipment. It includes self-locking casters, a lifting platform, a support platform, a support panel, an insertion device, a rotating device, a drilling device, a top-support device, a release device, a transmission device, and a removal device. The insertion device and the rotating device are mounted on the support platform. The drilling device is connected to the insertion device. Two top-support devices are symmetrically arranged on the support panel. The release device and the removal device are both mounted on the support panel. The transmission device is also mounted on the removal device. This device provides a convenient method for dismantling square timber and back bracing by using screws or similar methods to limit their position on the side of the bridge abutment. By saving time and effort and releasing most of the required pulling force to the ground, the stability and operational efficiency of this device are improved.
