[0002] A large amount of construction wastewater will be generated in construction projects. If the construction wastewater cannot be discharged in time, it will affect safe production. Therefore, the construction wastewater needs to be discharged in time using a drainage device. In order to avoid impurities in the wastewater clogging the pipes, a drainage device is needed to filter the impurities in the wastewater before discharging. After searching, the patent with application number 202320224718.3 discloses a construction engineering drainage device, which belongs to the technical field of construction engineering drainage. A construction engineering drainage device includes a box body, and a mounting frame is installed on the inner side of the box body near the middle, and a through hole is passed through the middle of the mounting frame.
