The invention belongs to the technical field of hydraulic engineering drainage, and particularly relates to a drainage device for hydraulic engineering construction, which comprises a delivery pump, the input end of the delivery pump is connected with a connecting pipe, flanges are arranged at the joints of the connecting pipe and the input end of the delivery pump, a filter sleeve is arranged at one end of the connecting pipe away from the flange I, and a filter mechanism is arranged in the filter sleeve; by arranging the filtering mechanism, impurities in water can be automatically filtered, the impurities are prevented from being directly sucked into the conveying pump, normal operation of the conveying pump is protected, the impurities can be concentrated to the joint of the two filtering plates, when a cleaning plate is attached to the surfaces of the filtering plates and moves, the impurities between the two filtering plates are cleaned, the filtering plates are prevented from being blocked, and the service life of the filtering plates is prolonged. And the number of times of frequent blockage cleaning can be reduced, continuous and efficient work is facilitated, impurities on the surface of the filter plate can be fully cleaned, the cleaning effect is further improved, and the water drainage efficiency and quality of the water conservancy project can be improved.

本发明属于水利工程排水技术领域，具体是一种用于水利工程施工用排水装置，包括输送泵，输送泵输入端连接有连接管，连接管与输送泵输入端连接处均设置有法兰，连接管远离法兰一的一端设置有过滤套，过滤套内设置有过滤机构；本发明通过设置过滤机构，能够自动过滤水中的杂物，避免杂物被直接吸入输送泵内，保护输送泵的正常运行，能够使杂物向两个过滤板连接处集中，当清理板贴合在过滤板表面并移动时，清理两个过滤板之间的杂物，防止过滤板堵塞，能够减少频繁清理堵塞的次数，便于持续高效进行工作，能够对过滤板表面的杂物进行充分的清理，进一步提高清理效果，能够提高水利工程排水的效率和质量。
